This message is sent when the clipboard contains a data handle for the CF_OWNERDISPLAY format (that is, the clipboard owner should display the clipboard contents) and an event occurs in the clipboard-application's vertical scroll bar.

Parameters

Contains a handle to the clipboard-application window.

lParam
