postmessage问题出在哪里？

[zhanghen888]

向窗口发送模拟“向下”的按键，为何没有反映
if (CreateProcess("E:\\ct\\Cargador.exe",NULL,NULL,
NULL,FALSE,0,NULL,"E:\\ct",&si,&pi)) {
dwProcessId = pi.dwProcessId;
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
hwnd=FindWindow(0,"推箱子");

Sleep(10000);
PostMessage(hwnd,WM_KEYDOWN,0x00000028,0x01500001);

PostMessage(hwnd,WM_KEYUP,0x00000028,0x01500001);
Sleep(1000);
PostMessage(hwnd,WM_KEYDOWN,0x00000028,0x01500001);

PostMessage(hwnd,WM_KEYUP,0x00000028,0x01500001);
Sleep(1000);
PostMessage(hwnd,WM_KEYDOWN,0x00000028,0x01500001);

PostMessage(hwnd,WM_KEYUP,0x00000028,0x01500001);

那个程序可能不是处理这个事件
我看用keybd_event来的保险些

我曾经也用PostMessage尝试也失败了，可能是我自己对PostMessage和SendMessage没用弄明白的缘故，不过我用keybd_event,例子如下：
模拟一次回车Press
keybd_event( 13, 0, 0, 0);// press Enter
keybd_event( 13, 0, KEYEVENTF_KEYUP, 0);

最好用SendMessage
PostMessage不判断是否成功就会返回。

检查一下：
hwnd=FindWindow(0,"推箱子");
看看hwnd是否为空。

先检查窗口是否找到,然后用sendmessage检查是否成功.
