Find info about a window

I found out the Yahoo Messenger window that notifies you when someone signs in or out is the only window that actually appears on top of a full screen movie or game and won't force you to exit full screen.

So my question is how can I find out what makes this window behave like this? I tried Spy++ but nothing interesting came up.

There are different ways to do this. Some video card drivers on older versions of windows will behave differently.

1) Grab the desktop hwnd and paint to it.

HWND hwnd = GetDesktopWindow();
HDC hdc = GetDC(hwnd);
RECT rect = {};

GetClientRect(hwnd, &rect); // dimensions of the primary monitor are rect.right,rect.bottom

// Use hdc to paint whatever you want to the screen

2) Just create a top-most window without a titlebar and use the WS_EX_TOPMOST style. Then draw whatever you want on it

CreateWindowEx(WS_EX_TOPMOST, ...);

Could be using the windows notification API (I don't have Yahoo messenger, so I'm not sure). Here's some more information about the notification area:
