When I make a DLL in MSVC 6.0 using __declspec(dllexport), the names of the functions show up with some extra chars, which specifies parameters and stuff in the dependency viewer. I noticed that no Windows, DirectX or any other DLL functions show up like that, they just show the normal, undecoreated name of the functions. How do I create DLLs where the function names show up as they do in code, and might this be the reason why my DLLs don''t want to work when used in VB?

to kill name mangling, use extern "C" on your exports.

to kill leading underscore and trailing @<stack bytes>, if you have them, create a def file and use EXPORTS statement to export functions by their actual names.

How do I use DEF files (like syntax or something)? I''ve never needed them before, so my knowledge of them is kind of limited...

you open the docs and read them. sample def file:

  
LIBRARY Cool

EXPORTS

InitializeCool
TerminateCool
DoSomethingCool

where the XXXCool functions are exported by cool.dll.

then modify linker options in your project settings to use the def file you''ve created.
