在windows环境下更改某软件的窗口位置

#include<stdio.h>

#include <time.h>

void main()

HWND win = FindWindowA("StandardFrame", "阿里旺旺");//获取窗口

int i = 0;
while (1)

POINT pt;
pt.x = pt.y = 0;//初始化
GetCursorPos(&pt);//获取位置

int data = rand() % 4;
switch (data)
{
case 0:
SetWindowPos(win, NULL, pt.x-500, pt.y-500, 0, 0, 1);//1禁止改变窗口大小
break;　　//如果x+的话，是向右移动，如果y+的话是向下移动。
case 1:
SetWindowPos(win, NULL, pt.x + 500, pt.y - 500, 0, 0, 1);//1禁止改变窗口大小
