Scrolling Support for ATL Composite Controls

Here's a class that I wrote that adds scrolling support to any ATL Composite Control.

The following steps are needed to add scrolling...

1. Include the ScrollImpl.h file

#include "ScrollImpl.h"

2. Add CScrollImpl to your inheritance tree

public CScrollImpl

3. Add the following entry to your Message Map

CHAIN_MSG_MAP(CScrollImpl)

4. Add a message handler for WM_INITDIALOG and add the following line to OnInitDialog...

SetScrollSize( m_hWnd, xScrollPos, yScrollPos );

5. Set xScrollPos to the position that you want horizontal scrolling to start and yScrollPos for the position you want vertical scrolling to start.
