推荐答案

您需要使用

You need to use the CScrollView[^] class; try a Google search for examples.

如果您将CScrollView用于该应用程序，则只需
调用以下方法

If you used the CScrollView for the application then just
call following method

void CScrollBarDlg::OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar) 
{
	// TODO: Add your message handler code here and/or call default
	int CurPos = m_ScrollBar.GetScrollPos();
	// Determine the new position of scroll box.
	switch (nSBCode)
	{
	case SB_LEFT:      // Scroll to far left.
		CurPos = 0;
		break;
	case SB_RIGHT:      // Scroll to far right.
		CurPos = 122;
		break;
	case SB_ENDSCROLL:   // End scroll.
		break;
	case SB_LINELEFT:      // Scroll left.
		if (CurPos > 0)
			CurPos--;
		break;
	case SB_LINERIGHT:   // Scroll right.
		if (CurPos < 122)
			CurPos++;
		break;
	case SB_PAGELEFT:    // Scroll one page left.
		{
			// Get the page size. 
			SCROLLINFO   info;
			m_ScrollBar.GetScrollInfo(&info, SIF_ALL);
   
			if (CurPos > 0)
				CurPos = max(0, CurPos - (int) info.nPage);
		}
		break;
	case SB_PAGERIGHT:      // Scroll one page right
		{
			// Get the page size. 
			SCROLLINFO   info;
			m_ScrollBar.GetScrollInfo(&info, SIF_ALL);
			if (CurPos < 122)
				CurPos = min(122, CurPos + (int) info.nPage);
		}
		break;
	case SB_THUMBPOSITION: // Scroll to absolute position. nPos is the position
		CurPos = nPos;      // of the scroll box at the end of the drag operation.
		break;
	case SB_THUMBTRACK:   // Drag scroll box to specified position. nPos is the
		CurPos = nPos;     // position that the scroll box has been dragged to.
		break;
	}
	// Set the new position of the thumb (scroll box).
	m_ScrollBar.SetScrollPos(CurPos);
	
	CDialog::OnVScroll(nSBCode, nPos, pScrollBar);
}




///////bit you use CEditCntrl then Define the object of scrollview like CSrollbar and add following code in OnDraw() method

m_ScrollBar.SetScrollRange(0, 122);
