The Microsoft Foundation Classes (MFC), used with:

Microsoft Visual C++, 32-bit Editions, version 4.0
SUMMARY
The SPLIT32 sample demonstrates the following Microsoft Foundation Class
(MFC) programming concepts:
- 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.
- The CDocument variable m_bAutoDelete can be used to prevent the
destruction of a CDocument object if all views of the document
are destroyed.
- 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.
- 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.
- 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.
- CWnd::CenterWindow() can be used to position windows at the center
of the screen.

NOTE: The following Microsoft Software Library samples, which also replace
various views, are also available:
- VWRPLC32 (MDI)
- COLLECT (MDI)
- ENROLL (SDI)
- VSWAP32 (SDI)
To understand what the sample does, first execute the program. You will see
a main application window with a splitter window (CSplitterWnd) in its
client area. A selection dialog will be displayed in the first pane and a
view will be displayed in the second pane.
Click on the View 1 and View 2 buttons. Notice that the view in the second
pane will switch from one to the other. The view is changing, but after
looking at the source you'll see that the document stays the same.
