Creates a window and a worker thread.
virtual HRESULT PrepareWindow( );
Return Values
Returns NOERROR if successful; E_FAIL if unsuccessful.
Remarks
The base window class creates a window and a worker thread. The worker thread is responsible for pulling messages from the window's input queue and dispatching them as appropriate. The window and its thread are created by CBaseWindow::PrepareWindowand destroyed in CBaseWindow::DoneWithWindow. The window should also be initialized and uninitialized through CBaseWindow::InitialiseWindowand CBaseWindow::UninitialiseWindow, respectively. Having prepared a window and initialized it, the window can be sized using CBaseWindow::ActivateWindowand subsequently hidden using CBaseWindow::InactivateWindow.
