Create a static project and compare the project's setting (code generation, linking ect..) between them. so you'll know what to change.

Do the same thing what KaplanDani sad, but You must change include files from that static projrct to Your project.
See the difference in "stdafx.h" file.

Hi!
you must sets same option for using MFC (first tab in tne lib project settings window) as you use in the project where you want use your lib. Note runtime library settings also must be same (dynamic or static, single/multi threaded)
