How to Replace a View in a Splitter Window

SUMMARY

1. A ReplaceView() function can be created which replaces a view in a CSplitterWnd pane with another. The function replaces a view but uses the same CDocument object. This function can be helpful if a programmer wants to keep the same frame window and document for a splitter pane, and only wants to delete a view in a pane and replace it with another.
2. The CDocument variable m_bAutoDelete can be used to prevent the destruction of a CDocument object if all views of the document are destroyed.
3. The CWnd::PreCreateWindow() function can be used to prevent the main application from having a thick frame, thus preventing the user from resizing the main application window.
4. By trapping the WM_SETCURSOR, WM_MOUSEMOVE, and WM_LBUTTONDOWN messages of a CSplitterWnd, you can fix the splitter bars in a splitter window so that they can't be moved by the user.
5. CSplitterWnd panes can contain regular CWnd objects and are not limited to the use of CViews. This sample places a dialog in the first pane.
6. CWnd::CenterWindow() can be used to position windows at the center of the screen.
