怎么用C#实现一个对另外程序发键盘消息,就象按建精灵功能的.只是那个不能切屏

[yoyolee_lcj]

看过用SendMessage不过没有什么完整点例子,看了一头雾水

如何用程序实现键盘和鼠标的模拟？
there is an example how to use keybd_event in C#,maybe help you
using System;
using System.Runtime.InteropServices;
using System.Text;

namespace ConsoleApplication8{
class Class1{
[STAThread]
static void Main(string[] args){
// Display current status of keys.
Console.WriteLine(
"**BEFORE**\r\nCAP: {0}\r\nSCR: {1}\r\nNUM: {2}",
Keyboard.GetState(VirtualKeys.VK_CAPITAL)?"ON":"OFF",
Keyboard.GetState(VirtualKeys.VK_SCROLL)?"ON":"OFF",
Keyboard.GetState(VirtualKeys.VK_NUMLOCK)?"ON":"OFF"
);
//Toggle all the keys:
Keyboard.SetState(
VirtualKeys.VK_CAPITAL,
!Keyboard.GetState(VirtualKeys.VK_CAPITAL)
);
Keyboard.SetState(
VirtualKeys.VK_SCROLL,
!Keyboard.GetState(VirtualKeys.VK_SCROLL)
);
Keyboard.SetState(
VirtualKeys.VK_NUMLOCK,
!Keyboard.GetState(VirtualKeys.VK_NUMLOCK)
);
// Display new status of keys.
Console.WriteLine(
"\r\n**AFTER**\r\nCAP: {0}\r\nSCR: {1}\r\nNUM: {2}",
Keyboard.GetState(VirtualKeys.VK_CAPITAL)?"ON":"OFF",
Keyboard.GetState(VirtualKeys.VK_SCROLL)?"ON":"OFF",
Keyboard.GetState(VirtualKeys.VK_NUMLOCK)?"ON":"OFF"
);
Console.ReadLine();
}
}
public enum VirtualKeys: byte{
VK_NUMLOCK = 0x90,
VK_SCROLL = 0x91,
VK_CAPITAL = 0x14
}
class Keyboard{
const uint KEYEVENTF_EXTENDEDKEY = 0x1;
const uint KEYEVENTF_KEYUP = 0x2;
[DllImport("user32.dll")]
static extern short GetKeyState(int nVirtKey);
[DllImport("user32.dll")]
static extern void keybd_event(
byte bVk,
byte bScan,
uint dwFlags,
uint dwExtraInfo
);
public static bool GetState(VirtualKeys Key){
return (GetKeyState((int)Key)==1);
}
public static void SetState(VirtualKeys Key, bool State){
if(State!=GetState(Key)){
keybd_event(
(byte)Key,
0x45,
KEYEVENTF_EXTENDEDKEY | 0,
0
);
keybd_event(
(byte)Key,
0x45,
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
0
);
}
}
}
}
//and you can do mouse_event operation like it.

建议你参考 一下 《Microsoft C＃程序设计》（北大出版社，上下册带光盘160元），里面关于 鼠标和键盘的东西有详细的论述

对于模拟键盘，除了利用keybd_event，更简单的是使用sendkeys，而且keybd_event已经被sendinput取代。

具体代码参考：

对于模拟鼠标，只好用SendInput，
