Cannot load 32-bit DLL "name" (Error 1753)

TheMSsForum.com: The Microsoft Software Forum

Hi,

I created a dll using MFC AppWizard(dll). I had a test program writen
in VC++ 6. The dll worked fine with the test program. But I got
"Cannot load 32-bit DLL "name" (Error 1753)" in FoxPro. I am new to
VFP. Could anyone shed some light on this? Thanks in advance,

Carol

Can you post the code that's throwing this error?

Here is the code. Thanks

in .cpp:
long __cdecl MyDLLFunction()
{
}

in .def:
LIBRARY MyDll
EXPORTS
MyDLLFunction@1

in VFP:
DECLARE LONG MyDLLFunction IN "J:\Carol\MyDll.dll"
ReturnCode=MyDLLFunction()

Hi,

Perhaps a missing dependent dll ? Open MyDll.dll with \Program
Files\Microsoft Visual Studio\Common\Tools\DEPENDS.EXE to verify.

It may help to
#include <windows.h>

and define the function as
long __declspec(dllexport) MyDLLFunction()

I think DECLARE cannot handle the way you export the function as
ordinal number (MyDLLFunction@1).

And you definately need the skeleton for a DLL, a LibMain Function
of this kind:


BOOL WINAPI __declspec(dllexport) LibMain(HINSTANCE hDLLInst, DWORD
fdwReason, LPVOID lpvReserved)
{
switch (fdwReason)
{
case DLL_PROCESS_ATTACH:
// The DLL is being loaded for the first time by a given
process.
// Perform per-process initialization here. If the
initialization
// is successful, return TRUE; if unsuccessful, return FALSE.


break;
case DLL_PROCESS_DETACH:
// The DLL is being unloaded by a given process. Do any
// per-process clean up here, such as undoing what was done in
// DLL_PROCESS_ATTACH. The return value is ignored.


break;
case DLL_THREAD_ATTACH:
// A thread is being created in a process that has already
loaded
// this DLL. Perform any per-thread initialization here. The
// return value is ignored.

break;
case DLL_THREAD_DETACH:
// A thread is exiting cleanly in a process that has already
// loaded this DLL. Perform any per-thread clean up here. The
// return value is ignored.

break;
}
return TRUE;
}

Bye, Olaf.
