  • SB_LINEUP   Scroll one line up.

  • SB_PAGEUP   Scroll one page up.

  • SB_THUMBPOSITION   Scroll to the absolute position. The current position is provided in nPos.

Remarks

The Clipboard owner’s OnVScrollClipboard member function is called by the Clipboard viewer when the Clipboard data has the CF_OWNERDISPLAY format and there is an event in the Clipboard viewer’s vertical scroll bar. The owner should scroll the Clipboard image, invalidate the appropriate section, and update the scroll-bar values.

Note   This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
