如何在OD加载程序遇到入口点之前执行代码之二：静态装载DLL

编译器：VS2010

需要的知识：DLL的编写和使用

1.dllmain.cpp

// dllmain.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
					 )
{
	switch (ul_reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
		MessageBoxA(NULL,"DLL_PROCESS_ATTACH","TEST",MB_OK);
		break;
	case DLL_THREAD_ATTACH:
	case DLL_THREAD_DETACH:
	case DLL_PROCESS_DETACH:
		MessageBoxA(NULL,"DLL_PROCESS_DETACH","TEST",MB_OK);
		break;
	}
	return TRUE;
}

DLL_PROCESS_ATTACH:表示该DLL第一次装载进进程空间中执行的代码

DLL_PROCESS_DETACH:表示该DLL脱离进程空间时候执行的代码

MessageBoxA函数在windows.h头文件中

2.dllTesxt.cpp

#include "stdafx.h"
#include "dllTest.h"
#include <iostream>
using namespace std;
void Show(){
	MessageBoxA(0,"DIAT","",MB_OK);
}

3.dllTest.h
