【整理】c# 调用windows API（user32.dll）

User32.dll提供了很多可供调用的接口,大致如下(转自http://blog.csdn.net/zhang399401/article/details/6978803) using System;    using System.Collections.Generic;    using System.Linq;    using System.Text;    using System.Runtime.InteropServices;       namespace WindowsAPI

转整理分享C#通过user32.dll模拟物理按键操作的代码

对系统模拟按键方面的知识和按键映射代码做了一下梳理,在这里分享出来,适用于开发自动操作工具和游戏外挂. 主代码: public const int KEYEVENTF_EXTENDEDKEY = 0x0001; //Key click flag public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag [DllImport("user32.dll")] private static extern void keybd_event(

Python 调用 user32.dll

import ctypes h = ctypes.windll.LoadLibrary("C:\\Windows\\System32\\user32.dll") h.MessageBoxW(0, u'内容', u'标题', 0)

看看 user32.dll里有哪些导出函数,大家都会,但准确性???以MS dumpbin为标准,要做出来结果一模一样,才表示代码完全正确. 直接上代码: 1 // ListExport.cpp : Defines the entry point for the console application. 2 // 3 #include "stdafx.h" 4 #include <windows.h> 5 #include <winnt.h> 6 7 exter

Win32 API中的user32.dll中的ShowWindow方法参数整理

在使用ShowWindow方法来设置窗体的状态时,由于不知道参数值,用起来非常容易混乱,所以整理了以下其参数的枚举值,方便以后的的使用.   public class User32API { #region ShowWindow 方法窗体状态的参数枚举 /// <summary> /// 隐藏窗口并激活其他窗口 /// </summary> public const int SW_HIDE = 0; /// <summary> /// 激活并显示一个窗口.如果窗口被最小
