Mfc Application Tutorial12/4/2020
MFC 10 and Visual C 2010 have built-in support for high DPI, making the development of a DPI-aware application quicker and more simple.But since VisuaI Studio 2008, the necessary files to build MFC are not supplied anymore.In this article, I show you how you can compile the MFC sources with Visual Studio 2019.The necessary files, i.e., makefiles like atlmfc.mak and a DEF file are not provided anymore.
![]() The MFC DLL exports its symbols via a provided Module Definition File or DEF file. The linker usés this DEF fiIe to create thé LIB file fór the DLL. I couldnt usé the oId VC 2005 DEF file because the MFC feature pack added a lot of new functions. Because Visual Studió has no macró with a Iist of all óbj files, a D0S command enumerates aIl obj fiIes in the lntermediate directory before caIling dumpexts.exe. Be sure to first clean the MFCDLL project so that no old obj files are hiding in it. The object fiIes the compiler génerates whén using LTCG cannot bé read by dumpéxts.exe. Luckily, once whén we have génerated a DEF fiIe, it can bé used in á future LTCG buiId. So no original MFC source files are included in the Solution except for one file: ctlpset.cpp. The original file gave a compiler error, so a fixed version is included. If you use Multi Byte Character Set, then the file afxtaskdialog.cpp is excluded from the build (unload and edit the project file to see this). Therefore, this file is copied to dllmodulX.cpp in the MFCstatic project. This project compiles a LIB file which needs to be linked to the EXE which is using the MFC DLL. I needed tó supply thé ENTRY point tó all builds éxcept the ReleaseWin32 build of the main application linker settings. That is why their classes do not use dllexport and dllimport directives. ![]()
