Issues with GetProcAddress from my DLL

[Shaitan00]

Probably a pretty newbie question but I'm having a hard time how to correctly use GetProcAddress to gain access to a function in a DLL I wrote...

 

The following is in the a.dll file I created (the function I wish to expose):

 

A.cpp

BOOL DoWork (LPCTSTR a, DWORD b = 5000, BOOL c = TRUE, UCHAR d = 10, UCHAR e = 0)

[/Code]

 

A.h

[Code]
A_DLLPORT BOOL DoWork (LPCTSTR a, DWORD b, BOOL c, UCHAR d, UCHAR e);
[/Code]

 

Now, in my actual application I am trying to load the dll function DoWork as follows:

[Code]
HMODULE hModule = LoadLibrary ("a.DLL");
if (!hModule)
{
return;
}

BOOL (*DoWork) (LPCTSTR) = GetProcAddress (hModule, "DoWork");
if (!DoWork)
{
FreeLibrary (hModule);
return;
}

if (DoWork(something))
{
// do something //
}
FreeLibrary (hModule);
[/Code]

 

But this code doesn't compile, I get the following error:

error C2440: 'initializing' : cannot convert from 'int (__stdcall *)(void)' to 'int (__cdecl *)(const char *)'

This conversion requires a reinterpret_cast, a C-style cast or function-style cast

 

At this point its a litte hit-and-miss, I'm doing some reading and searching on how to properly use GetProcAddress() but I can't find examples that illustrate using it in the context I am trying to ...

 

Any help, ideas, or hints would be greatly appreciated...

Thanks,

C++ isn't even close to being my strong point so anything I say is suspect, however I think the problem is the fact you aren't casting the return from GetProcAddress to the correct type.

 

Something like

typedef BOOL (*DoWorkFunc)(LPCTSTR , DWORD , BOOL , UCHAR , UCHAR );

DoWorkFunc pDoWorkFunc = GetProcAddress (hModule, "DoWork");

might be closer to the right answer.
