calling code with MFC in non MFC environment
-
I am developing a COM based exe that needs some already available functionality ( which exists in the form a static library using MFC ( MFC statically linked ) ). The API's exposed by the static library use primitive data types such as int , unsigned char etc . However when I include the static library in the COM project, it gives me a linker error about some CString's used . This is how the code is organized static library header file mystatic.h
int LibFunc1( int in, char *out) ;static library source file mystatic.cppint LibFunc1( int in, char *out) { .. CString s = "Hello"; }Com Component using static library#include "mystatic.h" .. .. LibFunc1(x, y)I am wondering if there is a better way of re-using this as I dont want to rewrite the static library logic . Help is appreciated.Engineering is the effort !

What version of MFC is the library linked with? If CString is the only class you use, it's no longer part of MFC, and can be used without MFC. Mark

I have stated CString as an eg however the static library uses other classes such as CStringArray , CArray etc

Cool. What are the exact linker errors? From the code you've shown, the COM module shouldn't know anything about a CString in the library code. Mark
