Windows下控制鼠标移动和点击的C语言实现

用VC控制台程序来实现。其实这个程序实现的关键就是调用windows api中的user32.dll中的两个函数就搞定了，废话不多说，直接上代码。以下是代码中的两个关键函数封装，完整可运行代码请到http://download.csdn.net/detail/zjuman2007/9922444下载。

//this macro already defined
//const int MOUSEEVENTF_MOVE = 0x0001;      //移动鼠标
//const int MOUSEEVENTF_LEFTDOWN = 0x0002;  //模拟鼠标左键按下 
//const int MOUSEEVENTF_LEFTUP = 0x0004;    //模拟鼠标左键抬起 
//const int MOUSEEVENTF_RIGHTDOWN = 0x0008; //模拟鼠标右键按下 
//const int MOUSEEVENTF_RIGHTUP = 0x0010;   //模拟鼠标右键抬起 
//const int MOUSEEVENTF_MIDDLEDOWN = 0x0020;//模拟鼠标中键按下 
//const int MOUSEEVENTF_MIDDLEUP = 0x0040;  //模拟鼠标中键抬起 
//const int MOUSEEVENTF_ABSOLUTE = 0x8000;  //标示是否采用绝对坐标
