1.导入4个位图图像到当前工程内，建立四个基础变量，

private:
  int m_moveY;   
  int m_moveX;   //移动距离
  CBitmap m_bitmap[4];  //存储图像
  int m_nCurBitmap;  //索引

分别用于存储移动距离，存储图像，当前图像索引位置。

2.构造函数初始化：

CmyImage008View::CmyImage008View()
  {
    // TODO: add construction code here
    static int bitmap[]={IDB_BITMAP1,IDB_BITMAP2,IDB_BITMAP3,IDB_BITMAP4};
    m_moveX=20;
    m_moveY=10;
    m_nCurBitmap=0;
    for(int i=0;i<4;i++)
    {
      m_bitmap[i].LoadBitmapW(bitmap[i]);
    }
  }

3.完成OnDraw()函数

void CmyImage008View::OnDraw(CDC *pDC )
  {
    CmyImage008Doc* pDoc = GetDocument();
    ASSERT_VALID(pDoc);

    /*  if (!pDoc)
    return;  */
    CDC MDC;
    MDC.CreateCompatibleDC(pDC);
    CBitmap *pOldBitmap;
    BITMAP bm;
    pOldBitmap=(CBitmap*)MDC.SelectObject(&m_bitmap[m_nCurBitmap]);
    m_bitmap[m_nCurBitmap].GetBitmap(&bm);
    pDC->BitBlt(m_moveX,m_moveY,bm.bmWidth,bm.bmHeight,&MDC,0,0,SRCCOPY);
    MDC.SelectObject(pOldBitmap);
    MDC.DeleteDC();
    // TODO: add draw code for native data here
  }

4.完成OnCreat函数

int CmyImage008View::OnCreate(LPCREATESTRUCT lpCreateStruct)
  {
    if (CView::OnCreate(lpCreateStruct) == -1)
      return -1;

    // TODO:  Add your specialized creation code here

    //return 0;
    SetTimer(1,1000,NULL);
  }

5.完成OnTimer函数

void CmyImage008View::OnTimer(UINT_PTR nIDEvent)
  {
    // TODO: Add your message handler code here and/or call default
    CClientDC dc(this);
    m_nCurBitmap^=1;
    if(m_nCurBitmap>=2)
    {
      m_moveX+=10;
      if(m_moveX>300)
        m_nCurBitmap-=2;
    }
    else
    {
      m_moveX-=10;
      if(m_moveX<=10)
        m_nCurBitmap+=2;
    }
    OnDraw(&dc);
    InvalidateRect(NULL,TRUE);


    CView::OnTimer(nIDEvent);
  }

6.完成OnDestroy函数

void CmyImage008View::OnDestroy()
  {
    CView::OnDestroy();
    KillTimer(1);
    // TODO: Add your message handler code here
  }

完成后的头文件为：

// myImage008View.h : interface of the CmyImage008View class
//

#pragma once

{
