dll no workie

[nabeels786]

VB keeps saying "cannot find entry point", even when there is one!


heres the code

// fileshredderDLL.cpp : Defines the entry point for the DLL application.
//

#include "stdafx.h"
#include "fileshredderDLL.h"

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;
}

// This is the constructor of a class that has been exported.
// see fileshredderDLL.h for the class definition
CFileshredderDLL::CFileshredderDLL()
{ 

}
int CFileshredderDLL::test(){
	return 1;
}

int TEST2(){
	return 1;
}


// This is an example of an exported variable
FILESHREDDERDLL_API int nFileshredderDLL=0;

// This is an example of an exported function.
FILESHREDDERDLL_API int fnFileshredderDLL(void)
{
	return 42;
}

i try calling test(), TEST2(), and fnFileshredderDLL(void) from VB, and from each of there, it doesnt work

another ? - do i put all of my functions in the CFileshredderDLL class, or outside of the class?


thanks alot -

All of your functions need to be __stdcall to work in VB.

Might solve the problem, dunno =).

nope didnt work

[nabeels786]

i found a guide, and did it that way

the DLL is only 24kb


vs. the 100kb+ the other one was givin

You can't use C++ classes in VB unless you implement them as COM objects, so much is sure.

And as Zaei said, all functions must be __stdcall.
Remove the FILESHREDDER_API, it helps you nothing for VB. Write a .def file instead.
