WinG and Borland C++

I've just recompiled my 16-bit WinG app with Borland C++. There's a
documented bug with WinG which insists that it is loaded before
Toolhelp.dll. I have successfully done this with Visual C++ 1.52, does
anyone know how to do it with Borland C++ 4.5?

I am building using a .ide file, I linked to wing.dll by adding wing.lib to the project manually using add node, toolhelp.dll appears to be linked automatically as part of the standard libraries.

Thanks
Nathaniel

Do you use .mak (make) or .ide (project expert) files?Do you link toolhelp.lib & wing.lib at compile-time or load toolhelp.dll and wing.dll at run-time?

There is no toolhelp.lib in Borland's standard libraries. So compiler cannot (and does not) link automatically toolhelp.dll to your application.If you do not call toolhelp.dll in your program then there is no problem at all (according MS, problem exists if you use toolhelp.dll).You can check if compiler links toolhelp.lib by clicking 'Project->Generate makefile' and then searching for 'toolhelp.lib' in this file.

If you find 'toolhelp.lib' in .mak file, please post this file as comments.

You're right - it does not link to toolhelp.lib. However, my program calls various toolhelp.dll functions including timeSetEvent, the Borland standard libraries must import toolhelp.dll so there is no need for toolhelp.lib. So the problem is reduced to one of linking to wing.lib before the standard libraries. Presumably the only way to do this is to edit the makefile manually?

timeSetEvent is exported by winmm.dll, not by toolhelp.dll.

It seems that you should not care about toolhelp.dll.

Here is a list of exported functions for  toolhelp.dll:

      CLASSFIRST                      
      CLASSNEXT                      
      GLOBALENTRYHANDLE              
      GLOBALENTRYMODULE              
      GLOBALFIRST                    
      GLOBALHANDLETOSEL              
      GLOBALINFO                      
      GLOBALNEXT                      
      INTERRUPTREGISTER              
      INTERRUPTUNREGISTER            
      LOCALFIRST                      
      LOCALINFO                      
      LOCALNEXT                      
      MEMMANINFO                      
      MEMORYREAD                      
      MEMORYWRITE                    
      MODULEFINDHANDLE                
      MODULEFINDNAME                  
      MODULEFIRST

You can check this list by right-clicking on toolhelp.dll in explorer and then selecting 'Quick view' (for Win95/NT 4.0).

Toolhelp.dll is not documented by MS and Borland C does not link it.

Of course, you can manually change order of linking by editing makefile and then use make.exe instead of project manager to make project. But in my opinion there in no need to do so.
