Cannot Convert from CProgressWnd to CProgressWnd

I have a recursive function that takes a parameter of CProgressWnd. In the middle of the function there is a call to itself:

RetrieveFileNamesFrom(AddPath,backupLog,wndProgress);

It throws the error mentioned in the question title. I'm not sure why it would have a problem converting from itself to itself?? Anyone know why this is?

ptrennum,
Also, please post the class declaration for CProgressWnd.

Error:

DEclaration:

Please post the class declaration for CProgressWnd.

Particularly the constructors for class CProgressWnd.

Also please post the code for function 'CZip::RetrieveFileNamesFrom'
