我的MFC dll工程想用WTL的东西，但是为什么一包含atlapp.h就出现下面的错误
error C2664: 'CreateCompatibleDC' : cannot convert parameter 1 from 'struct HDC__ *' to 'class CDC *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
error C2065: 'SelectBitmap' : undeclared identifier
error C2440: '=' : cannot convert from 'int' to 'struct HBITMAP__ *'
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
但是用WTL appwizard生成的就不会有错误就究竟是为什么呢？

虽然名称可能一致
WTL都能看到源代码(静态链接),可以直接COPY
