O.P. Visual C++ 6.0 DLLs
I'm trying to make a DLL, but I keep getting "Cannot find entry point <function name> in <dllname>" errors. I've followed instructions from various website, but they all cause the same errors.
Can sombody zip up an example project for me so I can see where I'm going wrong?

O.P. RE: Visual C++ 6.0 DLLs
I'm trying to make one of my own... I've made the .cpp, h and def files and followed the instructions given on website. The DLL makes ok, but I can't call it from within VB

RE: Visual C++ 6.0 DLLs
Are you sure your exported functions are in the def file?
They should be, then compile and copy to the same directory as your VB exe.

RE: Visual C++ 6.0 DLLs
Hmm.. They may be mangled by your compiler. To find out, download dependencywalker from www.dependencywalker.com, and open your DLL.
More information of name mangling here: http://en.wikipedia.org/wiki/Name_mangling

It is mangled. Click F10 in Dependency Walker to unmangle all function names.
If it wouldn't be mangled it would be:

RE: Visual C++ 6.0 DLLs
Does your DLL has a DllMain function?

O.P. RE: Visual C++ 6.0 DLLs
code:
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
