I use the C++.NET to write a dll and call this dll using VB6.

VC++ Code

#include "stdafx.h
BOOL APIENTRY DllMain( HANDLE hModule,
                      DWORD  ul_reason_for_call,
                      LPVOID lpReserve
                   

   return TRUE

extern "C" __declspec(dllexport) int SPS_Add ( int i1, int i2

    int  sum

    sum = i1 + i2
    return (sum)

VB Code

Sub Mai
   Declare Function SPS_Add Lib "SPS.dll" (ByVal i1 As Integer, ByVal i2 As Integer) As Intege
 
 Dim a1 As Integer, a2 As Integer, sum As Intege
 Dim temp1 As Strin

 a1 =
 a2 =

 sum = SPS_Add(a1, a2
 temp1 = a1 & " + " & a2 & " = " & su
 MsgBox temp
End Su

I run the VB and get an error: "Bad DLL Calling Convention.".    What is wrong
