compiling a DLL

First , thank you for a great tool. 

I'm using the EXE-cutable right now, but would like to compile a DLL , however no luck so far. 
Compiling the exe in VC++ was easy 'cause there was already a project file for it, but I'm having trouble
doing the same for the DLL. I'm not a C++ guru, well, far from it, so if anybody can help me , that'd be great. 

I'm getting a 

fatal error C1083: Cannnot open include file: 'config.h': No such file or directory.

No matter where I create the project and where the config.h file is relative to the project directory, it
doesn't work.

Any help is appreciated.

Thank you

Jano
