afx_msg void OnHScrollClipboard( CWnd* pClipAppWnd, UINT nSBCode, UINT nPos );
pClipAppWnd

nSBCode
Specifies one of the following scroll-bar codes in the low-order word:
| 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, not used.
The Clipboard owner's OnHScrollClipboard 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 horizontal scroll bar. The owner 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 functions, 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_HSCROLLCLIPBOARD message.
