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 = 0; i < 50; 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 - 5, y, width, height, TRUE);
        Sleep(20);
        MoveWindow(hwnd, x - 5, y-5, width, height, TRUE);
        Sleep(20);
        MoveWindow(hwnd, x , y-5, width, height, TRUE);
        Sleep(20);
        MoveWindow(hwnd, x , y, width, height, TRUE);
        Sleep(20);

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

    return 0;
