windows编程之窗口抖动

仅仅让黑窗口抖动以供小白娱乐

 #include<stdio.h>
 #include<windows.h>

 int main()
 {
     RECT rect;//RECT定义了一个矩形结构体，存储矩形边框
     HWND hwnd = NULL, oldhwnd = NULL;//窗口句柄

     int x, y, width, height;
     int i;

     system("title Hello World!");//标题：Hello World

     for (i = ; i < ; i++)
     {
         hwnd = GetForegroundWindow();//获取活动窗口的句柄

         if (hwnd != oldhwnd)
         {
             GetWindowRect(hwnd, &rect);//获取指定窗口位置
             x = rect.left;
             y = rect.top;
             width = rect.right - x;
             height = rect.bottom - y;
             oldhwnd = hwnd;//保存新获取的句柄窗口
         }

         MoveWindow(hwnd, x - , y, width, height, TRUE);
         Sleep();
         MoveWindow(hwnd, x - , y-, width, height, TRUE);
         Sleep();
         MoveWindow(hwnd, x , y-, width, height, TRUE);
         Sleep();
         MoveWindow(hwnd, x , y, width, height, TRUE);
         Sleep();

         system("cls");//刷新缓冲区
         printf("对方给您发送了一个加长版窗口抖动\n");
     }

     return ;
