Give up early rather than late. Encapsulate your shared library
in a DLL with a C interaface or a COM DLL. Then you won't
have to deal with C++ source compatibility issues...

Alternatively, consider wrapping that Ultimate grid as an ActiveX
Control. Better yet - check if it's already available in that form
from the original vendor (it likely is). Then no need to deal with
MFC altogether...

Hi,

I have defined a class header as follows:

class CTest : public CWindowImpl<CTest CRichEditCtrl>,
public CRichEditCommands<CTest>

I have the above within a MFC application which is necessary because class
CTest will be part of a static library which needs to be used within a WTL
application used by programmer A and used with a MFC application used by
myself. Unfortunately, I cannot alter the MFC application to be WTL
because
it uses Ultimate Grid which is MFC. Hence reason why I am integrating WTL
code within a MFC application. Also, programmer A has to use WTL to avoid
MFC dependencies.

I receive the following errors:

Any assistance would be appreciated.
