If you need to receive all messages sent to a window in another application, you must use C++ to write a system hook.

There are a couple of Win32 API functions, IsIconic() and IsZoomed(), which you can P/Invoke to determine whether a window is minimized or maximized, respectively.

Their signatures are as follows:

[DllImport("user32.dll")]
static extern bool IsIconic(IntPtr hWnd);

[DllImport("user32.dll")]
static extern bool IsZoomed(IntPtr hWnd);

So, assuming you've been able to obtain the handle of the window you want to test (using Process.MainWindowHandle or otherwise), then these functions can tell you what the current window state is.
