编写打印功能遇到困难，实在解决不了，特来求助，急……

打印分页问题：
vc/mfc默认提供的“打印预览”里面有一个按纽是“下一页”，但是当我要打印的东西超过一页时，那个“下一页”的按纽根本不起作用。那么要如何实现分页打印的功能呢？

[livedeal]

在OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)里设置打印的页数
pInfo->SetMaxPage (nMaxPage);

void CXcjc::OnXcjcPrint()
{
int nCount=m_ctlXcjcList.GetItemCount();
if(nCount<=0)
{
AfxMessageBox("没有要打印的内容!");
return;
}
CString strCdbh1,strCdbh2;
strCdbh1=_T("");
strCdbh2=_T("");
int j=0;
for(int i=0;i<nCount;i++)
{
strCdbh2=m_ctlXcjcList.GetItemText(i,0);
if(strCdbh1!=strCdbh2)
{
strCdbh1=strCdbh2;
j++;
}
}
PRNINFO PrnInfo = {0};
PrnInfo.hListView = m_ctlXcjcList.m_hWnd;
PrnInfo.hWnd = this->m_hWnd;
PrnInfo.IsPrint = FALSE;
PrnInfo.nCurPage = 1;
PrnInfo.nMaxLine = j*4;
if(m_strWtbh.GetLength()>1)
sprintf(PrnInfo.szTag,"%s",m_strWtbh.GetBuffer(1));
CPreParent DlgPreView;
DlgPreView.SetCallBackFun(DrawInfo, PrnInfo);
DlgPreView.DoModal();
}
void CXcjc::DrawInfo(CDC &memDC, PRNINFO PrnInfo)
{
if(memDC.m_hDC == NULL)
return;
int nCurPage = PrnInfo.nCurPage; //当前页
BOOL IsPrint = PrnInfo.IsPrint; //是否打印
int nMaxPage = PrnInfo.nCountPage; //最大页码
HWND hWnd = PrnInfo.hWnd;
HWND hList = PrnInfo.hListView;
CString csRFinality;
CString csLFinality;
csRFinality.Format("第 %i 页/共 %i 页", nCurPage, nMaxPage);

TCHAR szTitle[] = TEXT("现场检测采样记录");

int xP = GetDeviceCaps(memDC.m_hDC, LOGPIXELSX); //x方向每英寸像素点数
int yP = GetDeviceCaps(memDC.m_hDC, LOGPIXELSY); //y方向每英寸像素点数

int xPix = xP*10/240; //每 mm 宽度的像素
int yPix = yP*10/240; //每 mm 高度的像素
int fAdd = 5*yPix; //每格递增量
int nTitle=10*fAdd;
int nTop = 2*fAdd; //第一页最上
int nLeft = 15*xPix; //最左线
int nRight = xPix*(B5_W-20); //最右线
int nBottom = nTop+B5_ONELINE*fAdd;//底
int nTextAdd = 2*xPix;//文字起始位置
int iStart = (nCurPage - 1)*40;
这段代码是起打印输出作用，不知如何起到打印换页作用？

[heroful]

以上代码是定义打印输出作用，其内容采用
memDC.MoveTo(rt2.right, rt2.top);
memDC.LineTo(rt2.right, rt2.bottom);移动顺序
