使用SetWindowsHookEx的WM_PAINT挂钩 [英] WM_PAINT Hook using SetWindowsHookEx

问题描述

我的代码在这里

// hook.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <windows.h>
#include <iostream>

using namespace std;

LRESULT CALLBACK GetMsgProc(int code, WPARAM wParam, LPARAM lParam);

int _tmain(int argc, _TCHAR* argv[]){
int __;
cout << "Hallo World" << endl;
SetWindowsHookEx(WH_GETMESSAGE, GetMsgProc, 0, 0);
cin >> __;
return 0;
}

LRESULT CALLBACK GetMsgProc(int code, WPARAM wParam, LPARAM lParam){
cout << code << endl;
return 0;
}

我正在尝试获取WM_PAINT事件...此刻我正在尝试捕获所有事件.我在哪里失踪?

I am trying to get WM_PAINT event... at the moment I am trying to trap all the events. Where I am Missing ?

推荐答案

请阅读文档.它清楚地说明了为什么您的用法不正确，尤其是对于最后两个参数.如果要挂接每个线程，则需要提供一个模块 http://msdn.microsoft.com/zh-我们/图书馆/ms644990(v=vs.85).aspx

Read the documentation please. It clearly states why your usage is incorrect especially with regard to the last two parameters. If you want to hook every thread you need to provide a module http://msdn.microsoft.com/en-us/library/ms644990(v=vs.85).aspx
