Ok, thanks. I've found an Tutorial on this Page
https://forum.lowyat.net/topic/1344941/all and tried it Step by Step, but at Step 3: Compiling a DLL it stops.
I've tried to Compile a dll with VC++ 2008/2010 Express and get only errors, nothing will work.
Is something written wrong in the Tutorial?
Maybe anybody have a another working Tutorial?
