DLL trouble

[christheprogrammer]

Does anyone know a good FAQ for DLL building? I am having major problems figuring it out. i.e. Is the DLL the only file required at runtime? I am actually building DLL's to extend Python.

Thanks a million

there is also a Lib file what you can use for load the dll by default. There could be also a tlb file, but it also is not required. John Fill

In project settings under the link tab make sure you included the .lib file and the dll is in the same folder as the executable, system32, or in a pre-defined path

Oh one thing more. Pay attention if you use components and how are you linking, statically or dinamically John Fill

Thanks all,
I think I am just having trouble with Python loading the DLL, I got my DLL to build successfully and also the LIB file. Does anyone happen to know how to load these into Python using 'import x' ?
Cheers

Is error on loading or in callind dll functions? If is the second try to declare cunctions with __cdecl or __stdcall and see which one will work. John Fill

Sorry I don't understand what _cdecl or _stdcall are or where to use them...

for example instead of
int xxx();
you declare
__stdcall int xxx();
or
#extern "C" int xxx();
or
__cdecl int xxx();
also don't forget about
__declspec(dllexport) before function declaration is a requirement. John Fill
