Hello All,

I can't seem to call a DLL that I've written in Visual C++ without getting a General Protection Fault.
The problem is when I try to pass parameters. Functions that don't have parameters work fine.

C++ Code:

long SameNumber(long lReturnThis)
{

return lReturnThis;

}

Paradox Code:

Uses NetworkInfo

SameNumber(lNumber CLONG) CLONG

endUses

var

lResult LongInt

endvar

lResult = SameNumber(111) ; This is where the GPF occurs

What am I missing here?
Any help would be GREATLY appreciated.
Cheers,
John

Back again!
I found the solution to my own problem.
It was to do with the code produced by the Microsoft C++ compiler/linker.
By default Microsoft C++ compiles functions using the __cdecl parameter calling convention. The rest of the known world uses the __stdcall parameter calling convention.
As a result all the was needed was to change the function definitions in the C++ code, recompile and all was golden.

Before:

long SameNumber(long lReturnThis)

After:

long __stdcall SameNumber(long lReturnThis)

Cheers all. Have a good day!
John
