COM ATL DLL Query

[navraj]

Hi
I am trying to create a COM ATL DLL in that i add a method where i used the CDatabase class to access SQL. The problem is i must have the header file <afxdb.h> since i have added this header file its giving me an error on compilation saying "Windows.H is already included. MFC apps must not #include <windows.h>. May i know what is the problem

Something else is going on. windows.h can be included mutliple times since it, like all professional headers, has an inclusion guard.

Maybe you could post the exact error.

nothing..... u have to add/select "MFC support" while creating the COM Object.
