IS IT EVEN POSSIBLE???

I have a C program with a function that I would like to be able to call from Visual Basic. I am guessing the way to do this would be to make a DLL with MS Visual C++ (which I have), but I haven't the faintest clue as how to go about doing this. What would be the simplest, easiest, and quickest way to accomplish my objective?

Go to new Win32 Dll Project and put this in the code section:

void _stdcall Msg(HWND handle)
{ 
MessageBox(handle,"SomeText","Message",MB_OK);
}

Create a .def file in your project which contains:

LIBRARY "dllname.dll"
EXPORTS
Msg 1

This function displays a message box. To call it from VB use this:

Private Declare Sub Msg Lib "dllname.dll" (ByVal handle As Long)

Private Sub Command1_Click()
Msg Form1.hWnd
End Sub
