This topic provides information to help you determine the kind of DLL to build.

Different Kinds of DLLs Available
Using Visual C++, you can build Win32 DLLs in C or C++ that do not use the Microsoft Foundation Class (MFC) library. You can create a non-MFC DLL project with the Win32 Application Wizard.
http://msdn.microsoft.com/en-us/library/9se914de.aspx

The MFC library itself is available, in either static link libraries or in a number of DLLs, with the MFC DLL Wizard. If your DLL is using MFC, Visual C++ supports three different DLL development scenarios:

Building a regular DLL that statically links MFC

Building a regular DLL that dynamically links MFC

Building an MFC extension DLL, which always dynamically link MFC
