C语言标准库总结，用作平时不断总结...

1、windows.h

1. MessageBox 弹框

   #include <stdio.h>
   #include <windows.h>
   int main()
   {
   	//说明：n表示弹框点击按钮的返回的数字。第四个参数表示弹框样式(0~6)
       int n = MessageBox(0,"内容","标题",6);
       return 0;
   }
   

2. WinExec / ShellExecute 执行、打开

   #include <stdio.h>
   #include <windows.h>
   int main()
   {
   	//打开Xshell软件
       WinExec("D:\\java\\Xshell\\Xshell.exe",1);
       ShellExecute(0,"open","D:\\java\\Xshell\\Xshell.exe",0,0,1);
       //打开百度
       ShellExecute(0,"open","http://www.baidu.com",0,0,1);
       return 0;
   }
   

3. FindWindow 查找窗口

   #include <stdio.h>
   #include <windows.h>
   int main()
   {
       HWND h;//定义一个窗口句柄变量，用以存储找到的窗口句柄
       h = FindWindow(NULL,"a.txt - 记事本");//获得窗口名为"a.txt - 记事本"的窗口句柄
       SendMessage(h,WM_CLOSE,0,0);//调用SendMessage函数，发送一个WM_CLOSE（关闭）消息给wnd窗口句柄。
       return 0;
   }
   

4. GetCursorPos 获取鼠标坐标

   #include <stdio.h>
   #include <windows.h>
   int main()
   {
       POINT curpos;//一个可以存储点坐标的结构体变量
       while (true)
       {
           GetCursorPos(&curpos);//获取鼠标位置
           printf("%d,%d\n", curpos.x, curpos.y);//打印坐标
           Sleep(1000);//睡眠1s
       }
       return 0;
   }
