How to export dll function for VB

I'm trying to get a basic c++ dll written for use with a VB app but i'm stuck on what to put in the header. I don't want to use a def file and i think you have to use stdcall if calling it from VB. Any ideas ?

For example here's a function for the cpp file,

Code:

---

extern "C" __declspec(dllexport) long __stdcall FuncC( int JobNo )
{
        MessageBox(NULL, "_FuncC@4", "FuncC", MB_OK);
        return 0;
}

---

So what do i add to the header to export this ?

btw : i'm using devc++ which is probably a slightly different case from VC++.
