实现简单打印预览功能

打印预览实现流程:
     首先调用CFormView::OnFilePrintPreview,再依次调用自己的所重写的虚函数OnPreparePrinting(CPrintInfo* pInfo)、OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)、OnPrint(CDC* pDC, CPrintInfo* pInfo)、CFormView::OnPrint(pDC, pInfo);,当关闭打印预览时调用OnEndPrinting(CDC* pDC, CPrintInfo* pInfo)  ,结束打印。
部分代码:
  ON_COMMAND(ID_FILE_PRINT_PREVIEW, CFormView::OnFilePrintPreview)
  BOOL CElectronValveView::OnPreparePrinting(CPrintInfo* pInfo)
{
 // default preparation
  pInfo->SetMinPage(1); //设置打印文件起始页 
  pInfo->SetMaxPage(1); //设置打印文件终止页
  return   DoPreparePrinting(pInfo);

void CElectronValveView::OnBeginPrinting(CDC* /*pDC*/, CPrintInfo* /*pInfo*/)
{
 // TODO: add extra initialization before printing
  m_ChartCtrl.GetBottomAxis()->GetGrid()->SetColor(BlackColor);//设置栅格颜色为黑色,不然打印的时候太淡
  m_ChartCtrl.GetLeftAxis()->GetGrid()->SetColor(BlackColor);
}
void CElectronValveView::OnEndPrinting(CDC* /*pDC*/, CPrintInfo* /*pInfo*/)
{
 // TODO: add cleanup after printing
 m_ChartCtrl.GetBottomAxis()->GetGrid()->SetColor(BlueColor);//恢复颜色,不然控件中也是这个颜色了。
 m_ChartCtrl.GetLeftAxis()->GetGrid()->SetColor(BlueColor);
}
void CElectronValveView::OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
 // TODO: add customized printing code here
 CMainFrame* pMain=(CMainFrame *)AfxGetApp()->m_pMainWnd 
 CDC *pCurrentDC = GetDC();        // will have dimensions of the client area
 CSize PaperPixelsPerInch(pDC->GetDeviceCaps(LOGPIXELSX), pDC->GetDeviceCaps(LOGPIXELSY));
 //获得打印纸设备每英寸的像素数,应该是一样的。
    CSize ScreenPixelsPerInch(pCurrentDC->GetDeviceCaps(LOGPIXELSX), pCurrentDC->GetDeviceCaps(LOGPIXELSY));
 //应该是获得屏幕的每英寸的像素数,应该是一样的
 
 CSize m_PaperSize,m_LogicalPageSize;
 m_PaperSize = CSize(pDC->GetDeviceCaps(HORZRES), pDC->GetDeviceCaps(VERTRES));
 //把纸张所得的像素对应的屏幕大小得到。
 m_LogicalPageSize.cx = ScreenPixelsPerInch.cx * m_PaperSize.cx / PaperPixelsPerInch.cx * 3 / 4;
 m_LogicalPageSize.cy = ScreenPixelsPerInch.cy * m_PaperSize.cy / PaperPixelsPerInch.cy * 3 / 4;
 
 //这里必须这样设,是为了和ChartCtrl中的打印对应起来。
    pDC->SetMapMode(MM_ANISOTROPIC);
    pDC->SetWindowExt(m_LogicalPageSize);
    pDC->SetViewportExt(m_PaperSize);    
    pDC->SetWindowOrg(0, 0);   
 
 CRect rcClient,rcClient1;
 GetClientRect(&rcClient1); //得到的仍然是打印预览显示客户区的大小
 rcClient=pInfo->m_rectDraw;//打印纸的客户区
 double ratioX,ratioY;
 ratioX=(double)rcClient.right/(double)rcClient1.Width();
 ratioY=(double)rcClient.bottom/(double)rcClient1.Height();
 int nWid,left,right;
 CFont *pOldFont;
 CFont fnBig,fnBig1;
 CPen Pen,*OldPen;
 
 //画主框
 Pen.CreatePen(PS_SOLID,2,RGB(0,0,0));
 OldPen=pDC->SelectObject(&Pen);
 pDC->Rectangle(20,20,m_LogicalPageSize.cx-20,m_LogicalPageSize.cy-20);
 pDC->SelectObject(OldPen);

 //画标题栏
 pDC->MoveTo(20,60);

 //最后一栏
 fnBig.DeleteObject();
 fnBig.CreatePointFont(130,"宋体",pDC);
 pDC->SelectObject(&fnBig);
 pDC->TextOut(m_LogicalPageSize.cx-180,m_LogicalPageSize.cy-20-20,"审核:");
 pDC->SetTextAlign(TA_LEFT);

 CPoint offset(16,110);
 m_ChartCtrl.Print1(offset,pDC,pInfo,0);//调用chart类来画表格和曲线
 fnBig.DeleteObject();

 CFormView::OnPrint(pDC, pInfo);
}
本程序利用ChartCtrl来实现绘制表格和曲线。
