I want to call a DLL function that will return me a device handle, but i'm
having problems with the argument type.

The C Header file has this declarations:

typedef void *FT_HANDLE;

int  M_createC(OUT FT_HANDLE *ftCont);

In Visual Basic I did this:

Public Declare Function M_createC Lib "myLib.dll" ( _
      ByRef ftContext As Any) As Long

sub temp()

   Dim rc As Long
   Dim g_Context As Long

   rc = M_createC(g_Context)  <-- The Error is: "Bad DLL calling convention"

End Sub

Can you help me with this ? How can I call this DLL function ?

Thanks in advance
