windows编程之窗口抖动

仅仅让黑窗口抖动以供小白娱乐

 

 1 #include
 2 #include
 3 
 4 int main()
 5 {
 6     RECT rect;//RECT定义了一个矩形结构体，存储矩形边框
 7     HWND hwnd = NULL, oldhwnd = NULL;//窗口句柄
 8 
 9     int x, y, width, height;
10     int i;
11 
12     system("title Hello World!");//标题：Hello World
13 
14     for (i = 0; i < 50; i++)
15     {
16         hwnd = GetForegroundWindow();//获取活动窗口的句柄
17 
18         if (hwnd != oldhwnd)
19         {
20             GetWindowRect(hwnd, &rect);//获取指定窗口位置
21             x = rect.left;
22             y = rect.top;
23             width = rect.right - x;
24             height = rect.bottom - y;
25             oldhwnd = hwnd;//保存新获取的句柄窗口
26         }

28         MoveWindow(hwnd, x - 5, y, width, height, TRUE);
29         Sleep(20);

38         printf("对方给您发送了一个加长版窗口抖动\n");
