C语言实现窗口抖动

#include "stdafx.h"#include <stdio.h>#include<Windows.h>int main(){  int shake_time = 50; //休眠的时间，为5毫秒  int shake_distance = 10; //移动了10像素  RECT rect; //RECT是一个矩形结构体，相当于保存了一个矩形的四条边的坐标  HWND window = NULL, oldwindow = NULL; //两个窗口句柄  int x, y, width, height; //用来保存窗口横纵坐标和宽度、高度的变量  int i;  //抖50次吧  for (i = 0; i < 10; i++) {    window = GetForegroundWindow(); //拿到活动窗口    if (window != oldwindow) {      //获取指定窗口的位置      GetWindowRect(window, &rect);      x = rect.left;      y = rect.top;      width = rect.right - x;      height = rect.bottom - y;      oldwindow = window;    }    MoveWindow(window, x - shake_distance, y, width, height, TRUE); //移动窗口，向左移动了10像素，下同    Sleep(shake_time); //休眠time毫秒，线程休眠    MoveWindow(window, x - shake_distance, y - shake_distance, width, height, TRUE);    Sleep(shake_time);    MoveWindow(window, x, y - shake_distance, width, height, TRUE);    Sleep(shake_time);    MoveWindow(window, x, y, width, height, TRUE);    Sleep(shake_time);  }  return 0;}
