Solution 1

A WCHAR is a 16 bit character and your CString needs to be the same type. If your program is not being compiled for Unicode then you should use CStringW to ensure it is compatible with the source.

This pretty much sums it up... the CString has to be wide to be compatible.

Why do you need to convert it, you can display CStringW just the same as ordinary CString, as long as you use the wide version of any display function.
