- Taylor Hillegeist (26/50) Aug 25 2014 So, I figured it out! I used the wrong example for mydll.def.

I used the wrong example for mydll.def. --------------------------------------------- LIBRARY MYDLL DESCRIPTION 'My DLL written in D' EXETYPE NT CODE PRELOAD DISCARDABLE DATA WRITE EXPORTS DllGetClassObject 2 DllCanUnloadNow 3 DllRegisterServer 4 DllUnregisterServer 5 ---------------------------------------------- The above will cause errors: even though it makes you think that it should be mydll.def it is not. ---------------------------------------------- LIBRARY "mydll.dll" EXETYPE NT SUBSYSTEM WINDOWS CODE SHARED EXECUTE DATA WRITE ---------------------------------------------- The above is the correct .def contents Thanks all!
