用VC++2008建立了一个动态链接库,希望能供VB2008调用,但总是出错(VB2008与VC2008皆为速成版),下面是代码部分,请各位耐心看完.

---------------这是AddDll.cpp中的代码----------------

#include "winuser.h"

#include "stdafx.h"

#include "AddDll.h"

// 这是我的测试函数。

ADDDLL_API int __stdcall fnAddDll(int a, int b) { return a+b; }

--------------------------这是AddDll.h中的代码----------------------

#ifdef ADDDLL_EXPORTS

#define ADDDLL_API __declspec(dllexport)

#else #define ADDDLL_API __declspec(dllimport)

#endif extern ADDDLL_API int __stdcall fnAddDll(int a,int b);

------------------------这是def中的代码---------------------

LIBRARY AddDll EXPORTS fnAddDll @1

-------------------------这是VB2008中的代码----------------

Public Class Form1 Private Declare Function fnAddDll Lib "AddDll.dll" (ByVal a As Integer, ByVal b As Integer) As Integer

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim a As Integer

Dim b As Integer

Dim c As Integer

c = fnAddDll(a, b)

MsgBox(c)

End Sub

End Class

-------------------------------这是VB2008应用程序运行之后的提示--------------------------

Unable to find an entry point named 'fnAddDll' in DLL 'D:\Visual C++ 2008\AddDll\Release\AddDll.dll'.

这个提示大概是说找不到所调用函数的入口.就想用VC++2008写DLL,然后用VB2008进行调用,但是无论怎么努力都出错,本人是刚接触VS系列,希望 各位高手,能抽出空闲给出解答,最好能给出VC2008写DLL的步骤以及VB2008调用的详细步骤与说明,小生在此先谢过了.
