Several years ago, my company purchased a copy of the Version 3.0 GCL for MFC, Charting Tools and Real-Time Graphics Tools for Windows. The Quinn-Curtis DLLs function properly with MFC 4.2. Now that I am developing with Visual Studio VC++ 7.0, are there replacement DLLs that are compatible with MFC 7.0 and the GCL v3.0 libraries?
The DLL's are the same. What you need to do is re-compile the GCL libraries using the Visual Studio 7.0 compiler. This links in the version of MFC that ships with Visual Studio 7, rather than the ones that we ship, which linksin MFC from Visual Studio 6. The wct32dr3 and wrt32dr3 DLLs do not need to be re-compiled because they have no references to MFC in them.
All installations include GCL library source. Using Visual Studio 7.0, load the *.dsw projects in the QCW32\mfclib\source directory and do a Build | Batch Build | Select All | Rebuild on each. This remakes the GCL libraries and copies them to the QCW32\mfclib subdirectory.
