    Window not showing

    for some reason another window isnt showing in my program..hwnd shows but hwnd2 doesnt..

    Code:
    HWND hwnd , hwnd2;
    Code:
    hwnd = CreateWindowEx(0, szClassName, _T("Test") ,
    					  WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, CW_USEDEFAULT, CW_USEDEFAULT,
    					  425, 350, HWND_DESKTOP, NULL,
    					  hThisInstance, NULL);
    this is the main window...also the program is unicode

    Code:
    hwnd2 = CreateWindow(
    			szClassName,
    		    _T("test") ,
    			WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU,
    			CW_USEDEFAULT, CW_USEDEFAULT,
    			425, 350,
    			hwnd, NULL,
    			hThisInstance, NULL);
    thats the window im trying to get to show.

    Code:
    		ShowWindow(hwnd , SW_SHOW);
    		ShowWindow(hwnd2 , SW_SHOW);
    		UpdateWindow(hwnd);
    		UpdateWindow(hwnd2);
    it seems all perfect but wont show

    Since both windows are top level windows, try passing NULL as the parentHwnd argument to both calls.

    Are you sure they are not just overlapping? The styles you are using do not have a title bar or sizing border. Try adding WS_CAPTION.

    If the return value from CreateWindow or CreateWindowEx is NULL then you can use GetLastError to get more information about that error.

    I can't replicate the problem with the information you have supplied so all I can suggest is that you create a very minimal, compilable example and see if that gives you the same results. If it does then post/attach that code so we can take a look at it.
