c++ 模拟鼠标消息不成功

代码如下 希望能对计算器进行随机操作 但是没反应
#include "windows.h"
#include "winuser.h"
#include "iostream.h"
#include "cstdlib"
#include "ctime"

int main(int argc, char *argv[])
{
HWND hwnd3;
RECT rect;
while(1)
{
hwnd3=FindWindow(NULL,"计算器");
GetWindowRect(hwnd3,&rect);
int x1=rect.right;
int x2=rect.left;
int y1=rect.bottom;
int y2=rect.top;
srand(time(0));
int i,j;
for(int k=0;k<100;k++){
i=rand()%(x1-x2);
j=rand()%(y1-y2);
if(PostMessage(hwnd3, WM_LBUTTONDOWN, MK_LBUTTON, MAKELONG(i,j)))
cout<<MAKELONG(i,j)<<endl;
PostMessage(hwnd3, WM_LBUTTONUP, MK_LBUTTON, MAKELONG(i,j));
}
}
return 0;
}

win自带的计算器不支持外部消息~
