how to detect if window media player is running in full screen mode

How can I check if window media player is running in full screen mode & topmost in c++ MFC?
What I used is this logic:
I compared media player full screen coordinates to that of monitor coordinates.If they are same implies media player is in fullscreen.But it has one flaw.Whenever there are control(for play,pause) displayed in full screen in media player, coordinates are not coming same as that of monitor.

Need any other logic to implement this.

Code:

Need a C++ code to implement this logic.

Hi igor

can you add some explanation to your solution suggested.
I need a c++ code to implement that logic.

First of all, it's not clear from your OP whether the WMP is created by your app as WMPPlayer object, or you're talking about standalone WMP app running on the desktop.

My guess is you create WMP player object programmatically, so you can inspect the object property fullScreen. To give you "a c++ code" I need to know details how the WMP object was created, as well as how you access it at runtime. Code snippet would be very useful, first of all for you.

What about the CWnd::GetWindowPlacement method? If CWnd is maximized, the showCmd member of WINDOWPLACEMENT is SW_SHOWMAXIMIZED.

Hi igor,

The application I am working on is a MFC standalone application. Not using a IWMPlayer object etc. I need to take some action based on the applications running in fullscreen on Windows. For example if mspaint is opened in fullscreen or any other application is opened in fullscreen. Below is the code snippet

testFullScreenApp()
{
HWND hForeGndWnd = ::GetForegroundWindow();
if (hForeGndWnd == NULL)
{
return FALSE;
}

RECT deskRect = {0};
HWND hDesktopWnd = ::GetDesktopWindow();
if (hDesktopWnd)
{
::GetClientRect(hDesktopWnd, &deskRect);
}

WINDOWINFO wi = {0};
::GetWindowInfo(hForeGndWnd, &wi);

if ((wi.rcClient.left == wi.rcWindow.left && wi.rcWindow.left == deskRect.left) &&
(wi.rcClient.top == wi.rcWindow.top && wi.rcWindow.top== deskRect.top) &&
((wi.rcWindow.right-wi.rcClient.right <= 2) && wi.rcWindow.right == deskRect.right) &&
((wi.rcWindow.bottom-wi.rcClient.bottom <= 2) && wi.rcWindow.bottom == deskRect.bottom))
{

return TRUE;
}
}

This logic works fine for all applications except windows media player. If windows media player on desktop is running in fullscreen then this logic fails whenever there is display controls (play, pause etc) is in picture and works if they are not.

Please do the needful.

Sorry I can not help you with this. Fullscreen window is not obliged to be flagged maximized, BTW.

As you have a handle to the required window, what about using ::GetWindowPlacement such as

Code:

---

WINDOWPLACEMENT  wp = {0};
wp.length = sizeof(WINDOWPLACEMENT);
if (::GetWindowPlacement(hForeGndWnd, &wp)) {
      if (wp.showCmnd == SW_SHOWMAXIMIZED) {
        return TRUE;
      }
}

If GetWindowPlacement is not of help, what are the co-ordinates being returned when media player is full screen but control for play, pause etc is displayed? You will probably need to determine if foreground window is media player (from screen title) and then have seperate check for these co-ordinates.

Why do you need to know if full screen - what does your program do with the info? If media player window, you could maximise it and then return TRUE.

Code:

---

::ShowWindow(hForeGndWnd, SW_SHOWMAXIMIZED);
