WinCE进程ID获取窗口句柄

HWND hwndFind = NULL;

/*
1、枚举所有顶层窗口（不包括子窗口），并将窗口句柄依次传给回调函数
2、枚举结束条件：枚举完成或回调函数返回FALSE*/
BOOL bRt = EnumWindows(EnumWindowsProc, dwProcessId);

//回调函数
BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
    DWORD dwPI;

    GetWindowThreadProcessId(hwnd, &dwPI);
    if ( dwPI == (DWORD)lParam )
    {
        hwndFind = hwnd;
        return FALSE;
    }

    return TRUE;
}

MSDN说明：

• The EnumWindows function does not enumerate child windows. 

• This function is more reliable than calling the GetWindow function in a loop. An application that calls GetWindow to perform this task risks being caught in an infinite loop or referencing a handle to a window that has been destroyed.
