1. HOW TO GET HELP
-------------------
If you have any problems, please read this file, the
HELPME!.DOC and other files in your DOC subdirectory, and the
Borland C++ manuals first. If you still have a question and
need assistance, help is available from the following sources:
1. Type
GO BCPPDOS - for questions pertaining to DOS
or
GO BCPPWIN - for questions pertaining to Windows
on the CompuServe bulletin board system for
instant access to the Borland forums with their libraries of
technical information and answers to common questions.
If you are not a member of CompuServe, see the enclosed
special offer, and write for full details on how to receive
a free IntroPak containing a $15 credit toward your first
month's on-line charges.
2. Check with your local software dealer or users' group.
3. Borland's TECHFAX service. Call (800) 822-4269 for a FAX
catalog of entries.
4. If you have an urgent problem that cannot wait and you have
sent in the license agreement that came with the package,
you may call the Borland Technical Support Department at
(408) 461-9133. Please have the following information ready
before calling:
a. Product name and serial number on your original
distribution disk. Please have your serial number ready
or we will be unable to process your call.
b. Product version number. The version number for Borland
C++ can be displayed by pressing Alt-H/A in the IDE.
c. Computer brand, model, and the brands and model numbers of
any additional hardware.
d. Operating system and version number. (The version number
can be determined by typing VER at the DOS prompt.)
e. Contents of your AUTOEXEC.BAT file.
f. Contents of your CONFIG.SYS file.
2. INSTALLATION
----------------
You MUST use the INSTALL program to install Borland C++. The
files on the distribution disks are all archived and have to be
properly assembled. You cannot do this by hand!
Installing to the same directory structure as a previous version
without erasing the directories is not recommended; you may
encounter problems due to old header files, libraries, memory
managers, or configuration files.
To start the installation, change your current drive to the one
that has the install program on it and type INSTALL. You will
be given instructions in a box at the bottom of the screen for
each prompt. For example, if you will be installing from drive
A:, type:
A:
INSTALL
- This INSTALL handles the installation of both the compiler
and debugger and tools in one operation, and allows several
new configuration options.
- Note: The list of files is contained in a separate file
called FILELIST.DOC, which will appear in the target
directory you specify during installation.
- After installation, make sure you insert \BORLANDC\BIN - or
whatever you selected as your BIN directory - into
your DOS path so the DLL and executable files can be found.
- If you have previously installed Resource Workshop, make sure
that you remove the directory of that version from your path. The
version included on these disks supercedes previous versions.
- If you use a Windows command shell other than Program Manager,
you may not get a Borland C++ group installed for Windows. If
you don't, use File|Run in Program Manager to run the following
command:
GROUPS GROUPS.B$$
You will then have a new group for Borland C++.
- After your initial installation, you can run INSTALL again to
add elements you omitted the first time. Select only the
things you want to add in the INSTALL options screen. Because
some things you may want to save could be overwritten, review
the following items to make sure you don't lose important
information:
1. Selecting CMD (the Command-line compiler) causes an
overwrite of any existing TURBOC.CFG & TLINK.CFG file
with path information provided in that INSTALL session.
Any switches that you have added will not be preserved.
2. By selecting any one of the following, the help file
paths and choices for THELP.CFG will reflect the current
session's installation choices:
a. CMD - command-line compiler
b. IDE - integrated environment
c. TD - Turbo Debugger
d. TASM - Turbo Assembler
e. TV - Turbo Vision
f. OWL - ObjectWindows library
3. If you have made any alterations to headers or startup files
they will be overwritten if any library models are selected.
4. Selecting the Create BorlandC++ Group option will add a
group to the desktop and insert the appropriate icons
into that group if this is a first time installation. If
this is a re-installation this option will insert the
appropriate icons into the existing group.
In general, any selection you make of something installed
earlier will cause an overwrite of the earlier version
without prompting.
An attempt to install to a network directory for which you
don't have delete rights will fail with the message "Invalid
directory." Make sure delete rights are secured before
attempting an installation to a network.
You should read the rest of this README file to get further
information about this release before you do the installation.
See also the files in the DOC subdirectory after installation
for general information not included in the manuals.
3. NEW FEATURES
----------------
- Borland C++ for Windows: A Windows-hosted IDE which produces
Optimized code. The same Optimization options available in BC.EXE
are in BCW.EXE.
- Color syntax highlighting: All IDEs now highlight your source
according to syntax. See the choices under Options|Environment|
Colors|Edit Window in the DOS IDE and Options|Environment|
Highlight in the Windows IDEs. This option is enabled by
Options|Environment|Editor|Syntax Highlighting.
- 386 code generation: An option has been added to produce 386
instructions in the generated code. Use -3 at the command line,
or Options|Compiler|Advanced Code Generation|80386 in the IDEs.
- The Object Data calling convention for improved efficiency of C++
code. See the User's Guide chapter, "The Command-line Compiler",
under the option -po for more information. This option is also
available under Options|Compiler|Optimizations|Object data calling
in the IDE.
- Windows 3.1 support: All executables and DLLs have been modified
appropriately for compatibility with Version 3.1 of Windows.
The ObjectWindows Library header files have been modified for
compatibility with the new Windows header files as well.
NOTE CONCERNING USE OF MICROSOFT WINDOWS 3.1 REDISTRIBUTABLES FOR
APPLICATIONS RUNNING ON MICROSOFT WINDOWS 3.0
This Borland language product contains everything you need to develop
applications to run on the most recent version of Microsoft Windows,
version 3.1. In some cases, you may need to copy and include in your
application one or more Microsoft "redistributable" files from a copy
of version 3.1 so that your application will also run on version 3.0.
Microsoft informs us that you may copy the redistributable files from
from Microsoft Windows 3.1 for this purpose. If you do so, you must
comply with the conditions stated in the Borland No-Nonsense License
Statement included in this package as if the redistributable files you
copy were a part of this Borland language product. Microsoft's
redistributable files in Windows 3.1 are:
winhelp.exe, winhelp.hlp, commdlg.dll, ddeml.dll, toolhelp.dll,
vtd.386, olecli.dll, olesvr.dll, ver.dll, lzexpand.dll,
expand.exe, regload.exe, stress.dll, dib.drv, markmidi.exe,
penwin.dll, and shell.dll.
If you do not find any of these files in the BIN directory, they
are also included in the Windows retail distribution, and installed
in your Windows directories.
- WinSpector, a postmortem Windows debugging tool that traps
general protection faults and provides information on where
the fault occurred and the state of the machine at the time.
- You can now increase the number of files that can be open
at one time in a DOS program by a simple modification of the
runtime library.
First, modify _NFILE.H in your INCLUDE directory by changing
the #define for _NFILE_:
#define _NFILE_ n
where n is the number of files you want to open. Make sure the
FILES statement in your CONFIG.SYS file specifies at least
this number.
Then compile the two files FILES.C and FILES2.C in the LIB
directory:
BCC -c -m<model> files.c files2.c
where <model> is the memory model you're using.
Then link them directly with the program which opens the files,
for instance:
BCC myfile.c files.obj files2.obj
If you want the change to apply to all modules, add
FILES.OBJ and FILES2.OBJ created above to the libraries
you use; from the LIB directory, type:
TLIB c<model> +-files.obj +-files2.obj
where <model> matches what you used for the BCC command
above.
DPMI
----
BC.EXE, BCC.EXE, MAKE.EXE, and TLINK.EXE are now hosted under
DPMI. These files replace both the files with the same name in
Borland C++ 2.0 and the BCX.EXE, BCCX.EXE, and TLINKX.EXE files
in the same product. There is no longer a TKERNEL.EXE file.
Important!
----------
You must have at least 1Mb of extended memory to run these programs.
If you encounter a "machine not in database" message while attempting
to run the compiler, run the DPMIINST program to add your machine
configuration to the DPMI server database.
This version includes a resident DPMI host program, DPMIRES.EXE,
that allows you to preload the server before invoking BC, BCC, or
any other DPMI-hosted executables. If you want to run such hosted
EXEs in a Windows Standard Mode DOS window, you should run
DPMIRES.EXE before loading Windows. To do this, enter the
following commands at DOS:
set DPMIMEM=MAXMEM 2000
dpmires
win /s
If you want to limit the amount of extended memory used by the
DPMI-hosted executables, an environment variable called DPMIMEM
can be set to do so. For instance, the command
set DPMIMEM=MAXMEM 2000
reserves about 2 Mb of memory for DPMIRES. The number after MAXMEM
can be adjusted, but cannot be lower than 1000.
DPMIRES should not be run before running Windows in Enhanced Mode.
Windows requires its own DPMI services.
The hosted executables cannot spawn each other when SHARE is loaded.
For instance, if you run MAKE on a file which in turn calls MAKE
again, you will get a sharing violation. In this specific case,
you can call the real mode version, MAKER, within the given makefile,
and a sharing violation won't occur.
Note to OS/2 users: To run any DPMI-hosted executables, like BC, BCC,
or TLINK, in a DOS Window, you need to enable DPMI for that window:
- Click the right mouse button on a DOS window icon in Command
Prompts
- Select Open|Settings|Session|DOS Settings|DPMI_DOS_API and select
ENABLED.
Note to EMM386.SYS users: To run DPMI-hosted EXEs, under the EMM386
included with Windows 3.1, you need to apply a patch to our files
as follows:
- Go to the BIN directory
- Type the following command:
patch server.dif dpmi16bi.ovl
You will now be able to run BC, BCC, etc.
4. IMPORTANT INFORMATION
-------------------------
- There is now only one version of the DOS IDE, BC.EXE, and
of the command-line compiler program, BCC.EXE. Because the
BCX and BCCX files are no longer in Borland C++, you'll need
to alter batch or make files that use those names.
- Borland C++ only supports Protected Mode Windows target
files. Make sure to use the /t option when using the Resource
Compiler if you want to enforce Protected Mode usage.
- When using Brief with THELP, make sure to use Brief's -p
switch to ensure that the THELP window will be visible.
- We recommend that you use the following mouse drivers with
this product:
Microsoft Mouse version 7.04 or later;
Logitech Mouse version 5.01 or later;
Genius Mouse version 9.06 or later.
- If you use MAKE or the IDE's Project Make to invoke the Resource
Compiler, the .RC files you wish to compile MUST be in the same
directory as your project or makefile. This is because the Microsoft
Resource Compiler does not properly handle relative path names, and
returns a misleading error message that refers to an incorrectly
spelled version of your .RC file.
- If you get a "floating point formats not linked" message at
runtime, put the following somewhere in your source files:
extern void _floatconvert();
#pragma extref _floatconvert
This will force inclusion of floating point formats, which
may not be linked to reduce executable size.
- Make sure that you use the -WE switch (Options|Compiler|Entry|
Windows <DLL> explicit functions exported in the IDE) when
using the fastcall modifier. The same applies when using the
fastcall compilation option (-pr on the command line,
Options|Compiler|Entry|Register in the IDE.) Also see the first
entry on using fastcall with main() in "COMPILER" below.
- If the Windows 3.0 home directory precedes the Borland C++ BIN
directory in your path, attempting to access Help will result in the
message "This version of Help file not supported." To enable
Help, either reorder your path or copy WINHELP.EXE to your Windows
3.0 directory.
- This compiler uses more strict checking of C++ syntax and argument
matching than previous versions. You can expect more warning
and error messages based on the ANSI C++ version 3.0 standard.
- If you receive a "bad object record" message from the linker when
building OWL or container class library applications, you are
probably using the Borland C++ version 3.0 class libraries and/or
OWL libraries. Make sure your library path specifies version 3.1
libraries for those applications.
COMPILER
- When using fastcalls (-pr command line option) you are
required to explicitly use the C calling convention, "cdecl",
for main. For example:
int cdecl main( )
In Borland C++ 3.0 the compiler did not correctly name main when
fastcalls were used, with the result that you were not
required to cdecl main (in all cases). This is a dangerous
condition and the compiler now (correctly) names main,
resulting in a linker error in Borland C++ 3.1 for those Borland C++
3.0 compiled programs that didn't cdecl main.
Please correct any "non-cdecl main" definitions, if compiled
with fastcalls.
- In Borland C++ 3.0 the compiler allowed conversions from "const void*"
to "void *", contrary to ANSI; for Borland C++ 3.1 this is no
longer allowed. In addition, several other conversions
regarding const variables have also been restricted. If you
are a user of the const keyword, expect that you may have
conversions that were allowed to exist with Borland C++ 3.0 that
will need to be changed in order to compile using Borland C++ 3.1.
- In Borland C++ 3.0 the following syntax was allowed-
class foo{
...
} // note that the semicolon is missing here
f(){
...
}
The new compiler now requires the semicolon to be added after
the class declaration. The compiler would interpret the
example above as an attempt to return a class declaration to
f().
- A new implicit conversion rule is now enforced for constructors.
From page 573 of The C++ Programming Language 2nd Edition:
"When no constructor for class X accepts the given type, no
attempt is made to find other constructors or conversion
functions to convert the assigned value into a type acceptable
to a constructor for class X."
For example,
class X { /* ... */ X(int); };
class Y { /* ... */ Y(X); };
Y a = 1; // illegal: Y(X(1)) not tried
Note that this rule only applies to constructors with ONE parameter.
- The inport/outport functions have been changed to accept an
unsigned parameter instead of an int. The new prototypes are:
unsigned inport(unsigned)
unsigned char inportb(unsigned)
void outport(unsigned, unsigned)
void outportb(unsigned, unsigned char)
- We have new resource compiler and linker components:
BRCC is the Borland Resource Compiler. RLINK is the resource
linker/binder. BRC.EXE calls BRCC.EXE and RLINK.EXE, and is an
equivalent to Microsoft's Windows 3.1 RC. New features that
may not be found in other products include:
- Binding of multiple RES files is supported under RLINK.
- Resource ID conflicts are detected and resolved during
binding.
For more information, see the file MANUAL.RW located in your
\BORLANDC\DOC directory.
- There is currently support in ObjectWindows for STRICT and
non-STRICT versions of OWL programs for Borland C++ versions
3.0 and 3.1. Simply define the macros WIN30 or WIN31, and add a
definition for STRICT if you need STRICT compliance. For
more details see WIN31.DOC in the DOC directory and
OWL31.DOC in the OWL\DOC directory.
- The default extension for source files to the command-line
compiler is .CPP; that is, if you enter
BCC -c test
the compiler will search for test.cpp, and give an error if a
file of that name cannot be found. If you want to have the
command-line compiler assume a .c extension and C language
source, use the command-line option -P-c. For more
information, see "The command-line compiler" in the User's
Guide.
- Note that the Generate COMDEFs choice under
Options|Compiler|Code Generation and the -Fc command-line
option are only supported in the C language. Linker errors
will result if you attempt to use a communal variable in C++.
- The macros min() and max() are not defined when stdlib.h is
compiled as C++ (to allow their use in 3rd party libraries,
etc.).
- Note that files with the extension .SYM can come from at least
two different sources: Borland's precompiled headers, and the
output of Microsoft's MAPSYM or Borland's TMAPSYM programs,which
can also be used by SYMDEB and other debuggers.
These files do not have compatible formats, so collisions
should be avoided by renaming the precompiled header file
with -H=<filename> on the BCC command line, or as a BCC transfer
option in the IDE.
- There is now full support of distance modifiers (near and
far) used for class member pointers. Here are two sample
declarations and their meanings:
void (A::* far var) ();
this is a far variable 'var' of type 'void (A::*)()';
void (far A::* var) ();
this is a 'default distance' variable 'var' of type
'void (far A::*)()'
- You must use "smart callbacks" - -WS from the command line,
Options| Compiler|Entry/Exit Code|Windows smart callbacks in
the IDE - if your application uses classes whose code is in a
DLL. This applies especially in the case of a class
implemented in an EXE which is derived from another
implemented in a DLL, which normally applies for users of OWL
and other object-oriented class libraries.
- If you use C++ templates, and use a separate TLINK command
line rather than letting BCC invoke TLINK, you should make
sure that you turn on case-sensitive links with the /c switch.
IDE
- When debugging a mouse application the Options|Debugger|Display
Swapping option should be set to "Always" for best results.
- Defines entered under Options|Compiler|Code Generation entered
with semicolons don't apply to RC project items. If you need to
make multiple definitions for resource compilation in the IDE,
enter separate defines in the Project Local Options, for example:
-dDEF1 -dDEF2=1
- In the DOS IDE, the mouse cursor is turned off during compilation
for performance improvements.
- If you run File|Printer setup from BCW.EXE (or another Windows
application which has printer setup support) under the Windows
3.0 debugging kernel, you will get a System Error from Windows.
You must switch to the NODEBUG version to run this option.
- The initial block marking behavior in the IDE is determined
by which version of the IDE is used first after installation.
Invoking BCW.EXE first will cause Windows-style block marking
conventions to be in effect; otherwise the standard DOS IDE
behavior will be used. You can change the behavior by
selecting Options|Environment| Editor and changing the
settings for Persistent blocks and Overwrite blocks.
- The first time you open certain projects in Borland C++ for
Windows (BCW), you will get a dialog indicating that one or
more items will be converted. This will occur for all Windows
projects existing prior to BC 3.1 and for all DOS projects
that you open in BCW. The purpose of the dialog is to
indicate to you that certain changes need to be made to the
project to allow it to compile properly for Windows. DOS
projects that are opened in BCW will need to be changed to
target Windows, and many projects will need to generate 80286
code rather than 8088 code. You have several options
regarding saving the changes:
Don't auto save project
Warn before saving project
Save project now
The first option will be the most likely choice for DOS C++
programs that you bring up in BCW in order to browse classes.
When you close the project, it won't be saved, so that you don't
lose the options you have already set.
If you select the second option, you will be given the choice of
saving the project when you close it.
The last option saves the project with the new settings
immediately. For your current Windows projects, you will
probably want to choose this option so that this dialog will no
longer come up for the project.
- The RC.EXE included in this release targets Windows 3.1. You
will need to include the -30 option for RC files in any project
intended to run under Windows 3.0. Use Options|Transfer|Resource
Compiler|Edit|Command line, and change the entry to:
-30 $RC
If you use PRJ2MAK on a project which uses this option,
you will need to edit the resulting .MAK file, and move
the "-30" option to the RC line which links the .RES
file to the .EXE file. For instance, the line output by
PRJ2MAK may look like:
rc filename.res filename.exe
..
rc -30 <other options> filename.res filename.rc
Change this to
rc -30 filename.res filename.exe
..
rc <other options> filename.res filename.rc
Resource Workshop
- 256-Color bitmaps and RLE4 compression:
Due to problems with many 256-color display drivers for Windows
3.x, saving a bitmap with the RLE4 compression feature of
Resource Workshop enabled can fail to produce valid output files.
Under Windows, the display driver is responsible for providing
RLE compression when it is requested. However, because many
display drivers do not implement this feature correctly, we
recommend that you take the following steps when attempting to
use RLE4 compression:
1. Save the bitmap with the compression option set to "None".
This ensures that you will have a usable copy of your bitmap
if the remaining steps are not successful.
2. Set the compression option to "RLE4".
3. Select Resource|Save Resource As and save the bitmap under a
different file name.
4. Select File|Open Project and load the compressed version of
the bitmap.
If you cannot load the compressed bitmap, you must use the
uncompressed bitmap file you saved in step 1.
If your 256-color driver fails to compress the bitmap correctly,
contact the display driver vendor.
Flood-fill with the paint bucket tool
-------------------------------------
Because of problems inherent to display drivers, flood-filling a
section of a bitmap using the paint bucket tool can fail to
produce the desired result.
Resource Workshop provides an alternate version of the flood-fill
algorithm that is slower but more reliable than the version
provided by most Windows 3.x display drivers.
You can enable Resource Workshop's flood-fill algorithm by adding
a flag called "RWS_OwnFloodFill" to the Icon editor section
([RWS_Icon]) of WORKSHOP.INI. Set the flag to 1.
The edited section of WORKSHOP.INI should look something like
this:
[RWS_Icon]
RWS_OwnFloodFill=1
PercentLeft=50
ZoomLeft=8
ZoomRight=1
bVert=1
Contact the display driver vendor if you experience flood-fill
problems.
WinSight
- WinSight traces messages received by GetMessage or SendMessage. It
does not trace messages sent directly by function call such as
WM_INITDIALOG.
- Please note that messages displayed as "dispatched" are actually
intercepted at the time of GetMessage, not DispatchMessage.
EXAMPLE PROGRAMS
- When you are running any example programs that come with .PRJ
files, if you didn't use the standard directories when you
installed Borland C++ you will have to change the .PRJ file
to reflect your actual directory setup. Do this from inside
Borland C++ with Alt-O/D.
- When run under the Windows 3.1 debug kernel, many OWL examples will
cause a message to be displayed like these:
USER: Invalidation with fErase==FALSE prevents WM_ERASEBKGND
Kernel: GlobalCompact(FFFFFFFF), discarding segments
These messages are valid runtime warnings, but they don't
indicate improper implementation; they are supplied for the
information of the user or programmer under the debug kernel.
- To build the help file for the HELPEX example, go to the
EXAMPLES\WIN30 directory and type
hc helpex
LINKING C++ WITH C
- Linking C++ modules with C modules requires the use of a
linkage specification. Prototypes for C functions within C++
modules must be in one of the following forms:
extern "C" declaration
extern "C" { declarations }
For example, if a C module contains these functions:
char *SCopy(char*, char*);
void ClearScreen(void)
they must be declared in a C++ module in one of the
following ways:
extern "C" char *SCopy(char*, char*);
extern "C" void ClearScreen(void);
or
extern "C" {
char *SCopy(char*, char*);
void ClearScreen(void);
}
Failure to do so will result in "Undefined symbol" errors
during link. For further examples, see the standard header
files.
OPTIMIZATIONS
- When Ignore Aliasing is used - Options|Compiler|Optimization|
Assume no pointer aliasing , or -Oa from the command line -
some initializations could be skipped. This applies
only when Copy propagation -Op or Options|Compiler|Optimization|
Copy propagation is used as well (which is the case when
using -O2 or Options|Compiler|Optimization|Fastest Code.) The
following case illustrates the issue:
len = 0;
read(help_file, (char *)&len, 1);
read(help_file, (char *)title, len);
The initializion of len to the value 0 above will probably
not be reflected in the first call to read() if aliases are
ignored. If the initialization of len were guaranteed by the
call to read(), the first line would be unnecessary, and the
value in len would be assigned and passed to the second read
correctly. We recommend that you avoid using these options
together when explicit initializations are used in code
sequences like these.
TURBO DEBUGGER AND TOOLS
Debugging Multiple Applications under Turbo Debugger for Windows
================================================================
You can debug multiple applications under TDW as follows:
1. Load the first program to be debugged into TDW.
2. Once the application is loaded, press the F3 key to
display the Load Module Source or DLL Symbols dialog box.
3. In the DLL Name text entry box, enter the name of the
.EXE or DLL to add. If the .EXE or DLL resides in
another directory, you need to provide the full path.
4. Press the Enter key. TDW adds the program name to the
DLLs & Programs list box and puts the !! symbol after it.
5. Close the Load Module Source or DLL dialog box, return to
the Module window, and set any necessary breakpoints in
the first program.
6. Press F9 to run the first program.
7. Switch to the Windows Program Manager while the first
program is running and run the second program in the
usual way.
8. You see the display switch back to TDW with the CPU
window showing the start-up information of the second
application. Close the CPU window.
9. In the Module window, set any necessary breakpoints in
the second application, then press the F9 key to run it.
This method is useful for debugging DDE conversations or any
other inter-program communication in the Windows
environment.
TDW.INI, the Windows initialization file for TDW and TPROFW
===========================================================
TDW.INI is located in your local Windows directory. It is the
Windows initialization file used by TDW, TPROFW, and WREMOTE.
TDW.INI specifies the name and location of the Debugger DLL and
the video driver DLL (if any) in the [TurboDebugger] section.
It can also contain two other sections:
o [VideoOptions], where you put settings for the video DLL, if any
o [WRemote], where WRSETUP puts settings for remote debugging
and profiling
[TurboDebugger] section
-----------------------
WINDEBUG.DLL has been replaced by TDWIN.DLL. TDWIN.DLL can be
located anywhere you wish (usually the main Windows directory).
The DebuggerDLL entry must specify the full path to TDWIN.DLL.
For example, if TDWIN.DLL is in the WINDOWS3.1 directory, its
TDW.INI entry is
[TurboDebugger]
DebuggerDLL=c:\windows3.1\tdwin.dll
The VideoDLL entry indicates a video support DLL for 8514 or
Super VGA, because TDW doesn't support these video modes by
default. This entry must specify the full path to the DLL. You
can set various video options for the DLL in the
[VideoOptions] section. See the next section for a complete
explanation of video DLL and options settings.
SVGA support, the VideoDLL entry, and the [VideoOptions] section
----------------------------------------------------------------
TDW and TPROFW handle most of the popular 2, 4, 16, and 256-color
high-resolution Super VGA modes. If your card isn't supported
correctly, you need to use a special Super VGA (SVGA) DLL.
Currently, six DLLs are supplied with your language compiler to
support various SVGA and 8514 video cards and modes. These DLLs are
described in the next section. For information on how to specify the
Video DLL or its options, see the sections "The VideoDLL entry" and
"The [VideoOptions] section," which follow the "Video DLLs" section.
Video DLLs
----------
All the video DLLs described in this section are designed to work
with the most current Windows screen drivers for your video card. If
you're not sure if you're using the latest drivers, contact your video
card manufacturer for more information.
From time to time we have new DLLs for new video cards. These DLLs,
when available, can be downloaded from Compuserve, BIX, GEnie, and our
local BBS (408-439-9096). As new video cards and modes appear on the
market, we will be creating new DLLs for them. If the card you use
isn't supported by one of our DLLs, please contact Tech Support for
the latest video DLL information. Our main Tech Support phone number
is 408-461-9133.
ATI.DLL
-------
Works with the ATI VGA Wonder and XL cards in certain video modes.
The latest ATI Drivers from ATI Technologies Inc. require the
following TDW.INI file entries:
Resolution ATI.DLL Int2FAssist
-----------------------------------
| 640X480 | Yes | Yes |
-----------------------------------
| 800X600 | Yes | Yes |
-----------------------------------
| 1024X768 | No | No |
-----------------------------------
EXPLANATION: ATI.DLL is required in all video modes except
1024 X 768 (this mode is directly supported by TDW and TPROFW).
When the DLL is used (VideoDLL=ATI.DLL), Int2FAssist should be
set to "yes" in the [VideoOptions] section.
TSENG.DLL
---------
Supports TSENG ET-3000 /ET-4000 based cards in certain
video modes.
The latest TSENG drivers are available from the Microsoft
Windows Driver Library on CompuServe. They require the
following TDW.INI file settings:
Resolution TSENG.DLL Int2FAssist
-------------------------------------
| 640X480 | Yes | Yes |
-------------------------------------
| 800X600 | No | No |
-------------------------------------
| 1024X768 | No | No |
-------------------------------------
EXPLANATION: TSENG.DLL should only be used with 640 X 480 X 256
resolution (set VideoDLL=TSENG.DLL and put a "Int2FAssist=Yes"
entry in the [VideoOptions] section). TDW and TPROFW directly
support the other TSENG resolutions.
TDVESA.DLL
----------
Supports any video card that does VESA emulation, whether
through a TSR or video card firmware. Use this DLL with
all resolution settings.
NOTE: You can run VESATEST.EXE from either DOS or
Windows to see if your system provides the proper
VESA functions. If the emulation is not loaded, TDW
(or TPROFW) will display an error message indicating that
the video DLL isn't supported by the current configuration.
The TDVESA.DLL has been tested with the following video
cards:
o Video Seven VRAM II--uses V7VESA TSR supplied with card
o Weitek Power Windows--emulates VESA with firmware.
DUAL8514.DLL
-------------
Supports any dual-screen 8514 cards. This DLL is only for
systems that have two-color monitors, one attached to the VGA
card and one attached to the 8415/A card. It speeds up
performance by preventing TDW (or TPROFW) from doing some
things that aren't required in dual-monitor mode.
NOTE: Using this DLL is not the same as invoking TDW
with the -do parameter, which only specifies using a
monochrome screen.
STB.DLL
-------
Supports the MVP2 series of multi-screen video cards.
ULTRA.DLL
---------
Supports ATI Graphics cards, 8514 Ultra and Vantage cards
(8514/Ultra, 8514/Vantage, Graphics/Ultra, and Graphics/Vantage),
and 8514-based cards configured for a single monitor (including
most IBM 8514/A cards). If you use this DLL with an IBM 8514/A
card, set "ATI=no" in the [VideoOptions] section of TDW.INI.
The VideoDLL entry
------------------
To use an SVGA DLL, simply edit the TDW.INI file that the installation
program puts in your main Windows directory. You can modify TDW.INI
with any ASCII text editor. Under the section heading [TurboDebugger]
there is an option called "VideoDLL". This entry should equal the
path and filename of the DLL you want to use for SVGA support (see the
example later in this file).
If there's an error loading the DLL or if the DLL doesn't support
the selected card or mode, TDW (or TPROFW) reports the error in a
Windows dialog box. When this happens, TDW (or TPROFW) unloads the
DLL and exits. If this situation occurs, remove the DLL's name from
the VideoDLL line in the TDW.INI file or select a video mode that is
supported by that DLL.
The [VideoOptions] section
--------------------------
There are options you can set for the current video DLL. You list
these options under the [VideoOptions] heading in any order you like.
The following list shows all the video options:
o SaveWholeScreen -- default = no
o Int2FAssist -- default = no
o DebugFile -- default = <blank>
o IgnoreMode -- default = no
o ATI -- default = yes
o Rows -- default = 25
o RestoreTextScreen -- default = yes
DebugFile can be either blank or set to a specific filename. The other
four settings must be either "yes" or "no". Rows must be 25 or 50.
SaveWholeScreen (ATI, TSENG, TDVESA)
---------------
This option, normally set to "no", determines whether the entire
screen (512k - 64k from 8 planes) is saved (the entire graphics
screen is cleared when switching to it) or if only the top 32K of
planes 0 through 3 is saved (the entire screen is NOT cleared when
switching modes.)
Saving the whole screen is not usually necessary, but is provided
in case you're using a nonstandard card that requires that the whole
screen be saved. It also provides support for the Alt-F5 key
combination under Int2FAssist mode.
Int2FAssist (ATI, TSENG)
-----------
This option, normally set to "no", tells the DLL to make a special
Int 2F call before switching video modes. This call tells the current
Windows screen driver what's happening. The desired side-effect of this
call is to make Windows tell all its child windows to repaint
themselves. This option is provided mainly to support some ATI Wonder
and TSENG chip set video modes.
DebugFile (ALL DLLs)
---------
The video DLL normally doesn't log any debugging information. If
you're having problems using a particular DLL, you can use the
DebugFile option to specify the path and filename of a log file.
You can use the information logged to this file if you need to
contact Borland's Technical Support.
The information logged is:
o the date and time you ran TDW or TPROFW
o the version & location of the DLL
o the name of the current Windows screen driver
o the state of all TDW.INI options
o a listing of all calls and parameters to the DLL's functions
IgnoreMode (ATI, TSENG)
----------
This option only applies when the video DLL is ATI.DLL or TSENG.DLL.
It tells the DLL to not do any mode or card checking and to force the
Int2FAssist option on. This option is useful for cards that aren't
directly supported by an official DLL yet, such as Paradise, Video-7,
Trident, or any other video card without a graphics coprocessor.
(With this option enabled, the functionality is identical to the
temporary ALL.DLL that we offered in the past.)
ATI (ULTRA)
---
This option is only used by ULTRA.DLL and is on by default. If you
disable it, you can use ULTRA.DLL on regular IBM 8514/A cards.
ROWS (ALL DLLs)
----
This option is only used if you use a configuration file to change
the number of rows to 43/50 from 25. If you choose to have TDW
start in 50-line mode, set the Rows option to 50 in the TDW.INI file.
RestoreTextScreen (DUAL8514, STB)
-----------------
This option is valid only with DUAL8514.DLL and STB.DLL. The
settings are:
o Yes - restores TDW's (or TPROFW's) screen after exiting.
o No - does not touch TDW's (or TPROFW's) screen at all.
o Clear - forces the screen to clear upon exiting TDW (or TPROFW).
Video DLL example
-----------------
If you have an ATI VGA Wonder card and you want it to save
the entire screen and log information to a file named
C:\WINDOWS\TDVIDEO.LOG, the TDW.INI file will look something
like this:
[TurboDebugger]
DebuggerDLL=c:\windows3.1\tdwin.dll
VideoDLL=c:\borlandc\bin\ati.dll
[VideoOptions]
SaveWholeScreen=yes
DebugFile=c:\windows\tdvideo.log
Technical information
---------------------
TDW, upon loading, looks for the video DLL in the following
locations in the following order:
1. The same directory TDW (or TPROFW) is running from
2. The Windows main directory
3. The location specified in TDW.INI
If it finds the file, TDW (or TPROFW) accesses the DLL as needed.
TDW (or TPROFW) makes calls to the DLL to handle the entire video
screen-switching context. The DLL accomplishes the screen switching
by allocating a buffer as it gets loaded. Graphics screen contents
are then saved to this buffer when TDW (or TPROFW)_enters text mode.
The DLL restores the graphics screen from this buffer when TDW
(or TPROFW) exits text mode. Memory allocated for the buffer is freed
when the DLL is unloaded.
Seeing the user screen of an application
----------------------------------------
Some video modes might require some special handling. The Int2FAssist
option allows these modes to work correctly on most systems. The
behavior is as follows:
When you set "Int2FAssist=yes", the DLL notifies Windows to tell
all sub-windows on the screen to repaint themselves while the user
application is running. This allows the user screen to be viewed
when stepping, tracing, or running your application. It will not,
however, switch to the user screen when you press the Alt-F5 key
combination because TDW is still in control (TDW doesn't allow Windows
to process any messages at this point.)
If you also set "SaveWholeScreen=yes", pressing the Alt-F5 key
combination shows the user screen. (The DLL will now copy the screen
back for you.) The drawback to enabling SaveWholeScreen is that it
will take longer to step or trace if TDW needs to switch back to
the user screen for that particular instruction. Also, extra messages
will be passed to your application that normally wouldn't be passed.
This may affect the debugging of certain pieces of code (like finding
a bug in an owner-draw control). In these cases, you won't want to use
this option on the current video mode.
Using TDW in Dual Monitor Monochrome Mode
----------------------------------------
If TDW is activated using the -do switch, there is no need for
a video DLL or a value in the VideoDLL section of TDW.INI. The
value in VideoDLL should be removed as follows:
[Debugger]
VideoDll=
The [WRemote] section
---------------------
If you run WRSETUP to configure WREMOTE, the settings are
saved in the WRemote section of TDW.INI. In previous versions,
these settings were saved in the WRemote section of
WREMOTE.INI. If you have a previous version of TDW or TPROFW
and want to preserve your WREMOTE settings, you can append the
contents of WREMOTE.INI into TDW.INI. Be sure to include the
[WRemote] section heading.
The settings for the [WRemote] section are described in the
"Turbo Debugger User's Guide" in Appendix E, "Remote
Debugging" starting on page 386.
Known Problems
==============
- TD386 and TF386 currently do not support machines with over
16M of memory. You must disable any extra memory to use
these programs.
- On page 10 in Chapter 1 of the "Turbo Profiler User's Guide,"
there is a statement that Pascal versions of the PRIMEn.C
programs are included on disk. Only the C versions of these
sample programs are included on the distribution disks.
- Some mouse drivers are incompatible with TD and will
cause the mouse cursor to get scrambled when debugging DOS
graphics applications on a second monitor (-do option). If
that happens, you can try a different driver or turn off the
mouse in TD by using the -p- option on the TD command line.
The mouse will still be active in the target application.
- If you have any lines in your SYSTEM.INI that rename DLLs, such as
"sound.dll=mysound.drv", TDW might display the error "Can't find
sound.dll" when it loads a program that uses the DLL. To solve this
problem, use the -wd command switch to disable TDW's DLL checking when
you load such a program.
- The first time a program is run under TDW or TPROFW, mouse
messages are processed normally. However, on every subsequent
execution of that program, you must press a key on the
keyboard before mouse messages can be processed.
- TSENG ET-4000 video chip set and Windows 3.1 problems
Under Windows 3.1, if you use the standard Windows VGA or
SuperVga driver with a video card that uses the TSENG
ET-4000 chip set, you might encounter a number of problems
with running TDW on a single monitor.
o The hardware cursor (the white cursor displayed in all
dialog boxes that require text input) is invisible, but
you can still debug your program.
o On certain TSENG 4000-based cards (such as the Diamond
Speedstar VGA card), when you launch TDW the default
character set is replaced by graphic characters.
To overcome this problem please contact Microsoft Corp and ask
for the updated TSENG drivers that were NOT shipped with
Windows 3.1. They are also located in the Microsoft Forum (GO
MSOFT) under the Microsoft Software Library heading in
CompuServe.
Filenames Date
--------- ----
TSENG1.EXE 4/6/92
TSENG2.EXE 4/6/92
TSENG3.EXE 4/6/92
TSENG4.EXE 4/6/92
In the meantime, you can use one of the following alternatives:
- Run Windows Setup and replace your Windows 3.1 VGA or SVGA driver
with the Version 3.0 VGA driver supplied with Windows 3.1.
- Start TDW from the DOS command line. For example,
WIN TDW myprog
- Each time you launch Windows, run a full screen DOS session
and type "exit" to close it. After you do this, when you run
TDW, it will use the correct character set.
CLASS LIBRARY
- If you used the add(), addAt(), or getItemsInContainer()
member functions of the Array class in Borland C++ 2.0
applications, note that their behavior has changed slightly.
The following rules apply to these and related functions:
1. add() will insert its argument at the lowest available
location in the Array. This location is known as the
"insertion point".
2. detach() will remove its argument from the Array, and if
that Object is located below the insertion point, it
will move the elements above the Object being removed
and below the insertion point down one position, so that
the elements below the insertion point remain
contiguous. The insertion point, of course, moves down
one.
3. if the location specified in a call to addAt() is below
or at the insertion point, the elements above the
specified location and below the insertion point are
moved up one position, and the Object is inserted. The
insertion point moves up one.
4. if the location specified in a call to addAt() is above
the insertion point, the Object is inserted at that
location, replacing any Object that may have been placed
there previously.
5. getItemsInContainer() returns the number of elements
below the current insertion point. If you use addAt()
to add elements above the insertion point, they will not
affect the value returned by getItemsInContainer().
This is a change from the behavior in the previous
version of the class library.
- Two versions of the class library sources are provided; one
using an implementation using C++ templates, and one not using
templates. The small and dynamic link libraries are provided, and
a makefile is provided to build other models.
ObjectWindows Library
- You must rebuild the class libraries in the appropriate model
for the intended OWL model if they don't already exist - see
paragraph above.
- Due to restrictions on code size, compact model is no longer
supported for OWL applications.
- Note that you must use the TWindow member function AssignMenu
to assign a window's Attr.Menu member and to load a menu for
that window.
- You must alter project files and makefiles to indicate
compatibility with either Borland C++ version 3.0 or 3.1.
Add WIN30 for OWL projects from Borland C++ 3.0, or WIN31
for projects created under Borland C++ 3.1, to the defines
under Options|Compiler|Code Generation in the IDE, or passing
-DWIN30 or -DWIN31 to MAKE.
- World of ObjectWindows video users need to make modifications
to their Borland C++ 3.0 make or project files in order to
successfully compile their OWL code with Borland C++ 3.1. You
must define the WIN30 flag when compiling the OWL Video code.
In MAKEFILE.INC add the text, "-DWIN30" to the four 'CFLAGS'/
'CFLAGSD' lines. In all project files, you must go to Options|
Compiler|Code Generation and put WIN30 in the Defines combo box
field (at the bottom of this dialog).
Please see OWL31.DOC for additional information on ObjectWindows
Library.
TURBO VISION
- For information on the Help compiler, and how to build a help
document, please refer to the comments in the file TVHC.CPP in
the help directory. Also, see TVDemo for an example of how to
add help to your applications.
- Due to the complex interactions among the Turbo Vision classes,
certain situations can arise involving deletion of objects that
cannot be properly handled through destructors. Therefore, we
provide a static member function void destroy( TObject * ) to
the class TObject. Whenever an object of a type derived from
TObject is to be deleted, the function destroy() should be called
instead. This will take care of terminating the object,
correctly freeing the memory that it occupied. For example:
TDialog *dlg = new TDialog( ... );
//delete dlg; // DON'T DO THIS
destroy( dlg ); // DO IT THIS WAY
- The Turbo Vision Source Code is provided for your use and
modification. IMPORTANT: Borland Technical Support will not
answer questions or provide any assistance relating to this
product. Essentially, the Sources are provided "as is" and you
are on your own.
- In order to build the library, you must have Tasm available.
- When building or modifying the library it is better to place
debug info in only those modules in which you are interested.
If you place debug info all the modules, Tlink may not be able
to link your application.
- In order to build an overlayed Turbo Vision application with
Borland C++ 3.1, make sure you observe the following:
1. You need to rebuild the Turbo Vision library with
overlays. Change to the SOURCE directory under TVISION
and enter the command
make -DOVERLAY -B
This will produce a new version of TV.LIB which will
support overlays. It will also produce two .OBJ files,
SYSINT.OBJ and TEVENT.OBJ. These two files contain code
for TV's interrupt handlers, so they cannot be
overlayed.
2. When building an overlayed application, you must be sure
to link with the three files SYSINT.OBJ, TEVENT.OBJ, and
TV.LIB. The two .OBJ files must not be in overlays.
You also need to specify local virtual tables.
Your command line should look something like this:
bcc -ml -Vs -B -Yo myfile -Yo- sysint.obj tevent.obj -Yo tv.lib
See the Programmer's Guide for details on the meanings
of the various -Yo switches.
3. To improve performance, increase the size of the global
variable __ovrbuffer to 0x2000 or greater.
RUNTIME LIBRARY SOURCE
The Borland C++ Runtime Library Source Code is provided for
your use and modification. IMPORTANT: Borland Technical
Support will not answer questions or provide any assistance
relating to this product. Essentially, the Sources are
provided "as is" and you are on your own. If you find what you
think is a genuine problem with the source code, however, we
would like to hear about it. See "How to Get Help" above.
See CRTL.DOC for more information on building the Runtime
Library from source.
5. TESTING YOUR EXPANDED MEMORY: EMSTEST.COM
---------------------------------------------
Included with Borland C++ is a program to test your Expanded
Memory hardware and software. If you have problems using
Borland C++ with your EMS, type EMSTEST at the DOS prompt and
follow the instructions.
