n         方法2：

它是将类导出，但必须要有LIB文件，这种方法是静态调用!简单

 

DLL文件：MainDll.cpp

//---------------------------------------------------------------------------

 

#include <vcl.h>

#include <windows.h>

#pragma hdrstop

#pragma argsused

 

#include "MainDllTest.h"

//---------------------------------------------------------------------------

 

BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fwdreason, LPVOID lpvReserved)

{

  return 1;

}

//---------------------------------------------------------------------------

//下面是类的代码

TStaticClass::TStaticClass()

{

    FTimesCalled    = 0;

    m_AlreadySaidHi = false;

}

//---------------------------------------------------------------------------

TStaticClass::~TStaticClass()

{

 

}

//---------------------------------------------------------------------------

void __fastcall TStaticClass::SayHi(void)

{

    ShowMessage("调用DLL中类成功!");

    FTimesCalled++;

    m_AlreadySaidHi = true;

    ShowMessage("再试一次");

}

 

//下面是导出函数

//---------------------------------------------------------------------------

void __stdcall Say(char *WhatToSay)

{

    ShowMessage("来自EXE调用DLL中的函数\n" + (String)WhatToSay);

}

//---------------------------------------------------------------------------

 

DLL文件：MainDll.h

//---------------------------------------------------------------------------

 

#ifndef MainDllTestH

#define MainDllTestH

//---------------------------------------------------------------------------

//写个导出类
