I can understand CString not working since it changed after v6.0 and I
don't think there is a hashing function available, by default, to handle
CStrings. You could try using CMapStringToString for the first one or
CMapEx. What type of object is CMyClass? Could be a similar problem.

You may need a hashing function for your own class as well. These links
have examples:

I'm trying to move an MFC application from VS6 to VS2005, but I can't
compile
CMaps that use classes e.g.
CMap <CString, CString &, CString, CString &> map1;
CMap <class CMyClass, class CMyClass &, DWORD, DWORD &> map2;
Always complains with error C2440

Any suggestions?
Thanks
