CBaseWindow Class (Windows Embedded CE 6.0)

1/6/2010

This class creates a window and a worker thread.

The worker thread pulls messages from the window's input queue and dispatches them as appropriate.

The window and its thread are created by the CBaseWindow::PrepareWindow member function and destroyed by the CBaseWindow::DoneWithWindow member function.

The window should also be initialized by the CBaseWindow::InitialiseWindow member function and uninitialized by the CBaseWindow::UninitialiseWindow member function.

After preparing and initializing a window, size it by using the CBaseWindow::ActivateWindow member function; hide the window using the CBaseWindow::InactivateWindow member function.
