On the link editor to add MFC extension DLL yourself to do, the DLL interface classes, but in another program called, always can't contain the interface class, clearly.lib file has been loaded,
Fatal error C1083: cannot open include file: "ExtDLLClass. H" : No to the file or directory

This just a mistake, try to link the LIB file, write the name wrong VS will be unable to find a.lib file, so proved.lib file is loaded, but the header file is unable to contain,
Teaching CD give the source code can run normally, what do I really wrong,
