Creating an MFC DLL Project
An MFC DLL is a binary file that acts as a shared library of functions that can be used simultaneously by multiple applications. The easiest way to create an MFC DLL project is to use the MFC DLL Wizard.
The appearance of features in the IDE can depend on your active settings or edition, and might differ from those described in Help. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see.
