字画卷动类的实现代码

// public API

   // create the window; remove WS_VSCROLL to avoid showing scrollbar, remove WS_TABSTOP to disable keyboard scrolling.
   BOOL Create(const RECT& rect, CWnd* pParentWnd, UINT uStyle = WS_CHILD|WS_VISIBLE|WS_VSCROLL|WS_TABSTOP|WS_GROUP, UINT nID = 0);
   // activate/deactivate wrapping mode:
   void SetWrapping(BOOL bWrap);
   // Sets the color used for the background (if no pattern is set) or margins (if pattern is set and not tiled)
   void SetBgColor(COLORREF clrBg);
   // Sets the color used for text
   void SetFgColor(COLORREF clrBg);
   // Sets the font; size is in points, see LOGFONT documentation for weight constants
   void SetFont(const CString& strName, int nSize, int nWeight);
   // Sets the text to be displayed
   void SetText(const CString& strText);
   // Sets the bitmap to be displayed above the text
   CBitmap* SetLogo(CBitmap* pbmpLogo);
   // Sets the background pattern
   CBitmap* SetPattern(CBitmap* pbmpPattern, BOOL bTile);
   // Sets the time between frames (autoscrolling speed) (will revert to default if less than 0) (milliseconds)
   void SetScrollDelay(int nScrollDelay);
   // Sets the delay when autoscrolling pauses (will disable pausing if set less than scroll delay) (milliseconds)
   void SetScrollPause(int nScrollPause);

1.引入工程 CScrollerCtrl 类
2.

CScrollerCtrl  m_scroller;

3.在OnInitDialog中

    m_scroller.SetPattern(CBitmap::FromHandle((HBITMAP)::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_BITMAP2), IMAGE_BITMAP, 0,0, LR_SHARED)), FALSE); //设置的是背景图案
    m_scroller.SetBgColor(RGB(255,255,255)); //设置背景颜色
    m_scroller.SetFgColor(RGB(0,127,0)); // 设置前景色

  
   m_scroller.SetLogo(CBitmap::FromHandle((HBITMAP)::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_BITMAP3), IMAGE_BITMAP, 0,0, LR_SHARED)));// 画册logo
   // text
   CString strIntro;
   strIntro.LoadString(IDS_TEST);
   m_scroller.SetText(strIntro);   //设置内容

   CRect rect;
   GetClientRect(&rect);
   m_scroller.Create(rect, this);

    SetScrollDelay(1000);//设置卷动速度
