From where do you get a handle to your window?
If it is your applications main window, (if you are using e.g. mainwindow.run()) you shouldn't try to get a handle to your window in class constructor (unless you explicitly call Open() or OpenMain() -- which, in this case (if you already call run() in your apps main()) you shouldn't use).

You could use instead something safer:

HWND MainWindow::GetHandle()
{
return GetHWND(); // use IsOpen() to check before calling;
}

or

HWND MainWindow::GetHandle()
{
return IsOpen() ? GetHWND() : null; // handle null as an error;
}

and call whenever it's needed.
