◄CWnd► ◄Up► ◄Contents► ◄Index► ◄Back► ──Microsoft Foundation Classes────────────────────────────────────────────── afx_msg void OnVScrollClipboard( CWnd* pClipAppWnd, UINT nSBCode, UINT nPos ); Parameter Description <pClipAppWnd> Specifies a pointer to a Clipboard-viewer window. The pointer may be temporary. <nSBCode> Specifies one of the following scroll-bar codes: Value Description SB_BOTTOM Scroll to lower right. SB_ENDSCROLL End scroll. SB_LINEDOWN Scroll one line down. SB_LINEUP Scroll one line up. SB_PAGEDOWN Scroll one page down. SB_PAGEUP Scroll one page up. SB_THUMBPOSITION Scroll to the absolute position. The current position is provided in <nPos>. SB_TOP Scroll to upper left. <nPos> Contains the scroll box position if the scroll-bar code is SB_THUMBPOSITION; otherwise, <nPos> is not used. Remarks If the CWnd owns the Clipboard, the 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. OnVScrollClipboard should scroll the Clipboard image, invalidate the appropriate section, and update the scroll-bar values. The Clipboard owner should use the ◄Invalidate► or ◄InvalidateRect► member function or repaint as desired. The scroll-bar position should also be reset. This message-handler member function calls the ◄Default► member function. Override this member function in your derived class to handle the ◄WM_VSCROLLCLIPBOARD► message.
