Printing from within an ODBC SDI application

What is the best way to print a database in Access that I'm using in my ODBC SDI application? I don't have any sample code to do this. I don't want to see the data on the screen in the CView. I'm just using edit boxes to view the different fields of the records, scrolling and searching for a desired record. All works fine. The printing aspect seems a little more frightening.:)) Thanks for any help in this area.

You have to access each record at a time and print the individual fields. All this involves a bit of manual coding. Could you tell me how many fields are there(and their data types)?
thanks

Here is a sample that might be of use.
Make sure Print and Print Preview Options are set.
Use classwizard to map the following messages in the View class

//Comment out OnBeginPrinting and OnEndPrinting
#if 0
void CMyAppView::OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)
{
      // TODO: Add your specialized code here and/or call the base class
      
      //CFormView::OnBeginPrinting(pDC, pInfo);
}

void CMyAppView::OnEndPrinting(CDC* pDC, CPrintInfo* pInfo)
{
      // TODO: Add your specialized code here and/or call the base class
      
      //CFormView::OnEndPrinting(pDC, pInfo);
}

#endif

void CMyAppView::OnPrepareDC(CDC* pDC, CPrintInfo* pInfo)
{
      // TODO: Add your specialized code here and/or call the base class
      pDC->SetMapMode(MM_LOENGLISH);      
      //CFormView::OnPrepareDC(pDC, pInfo);
}

BOOL CMyAppView::OnPreparePrinting(CPrintInfo* pInfo)
{
      // TODO: call DoPreparePrinting to invoke the Print dialog box
      return DoPreparePrinting(pInfo);
}

void CMyAppView::OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
      // TODO: Add your specialized code here and/or call the base class
      CString str;
      CAbsprojDoc *pDoc=(CAbsprojDoc *)m_pDocument;
      pDC->SetMapMode(MM_TWIPS);
      CFont font;
      TEXTMETRIC tm;
      int nHeight;
      font.CreateFont(-180,0,0,0,400, FALSE, FALSE,
               0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,
               CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,
               DEFAULT_PITCH|FF_MODERN,"Courier New");
      CFont *pOldFont=(CFont *)(pDC->SelectObject(&font));
      pDC->GetTextMetrics(&tm);
      PrintPageHeader(pDC); //for any report header
      CPoint point(36,-1440);
      CString str1="SECTION",str2="DIFF NO.",str3="RANK",str4="COMMENTS";
      str.Format("%-65s%-10s%-8s%s",str1,str2,str3,str4);
      pDC->TextOut(point.x,point.y,str);
      nHeight=tm.tmHeight + tm.tmExternalLeading;
      point.y-=2*nHeight;
      pDC->MoveTo(point.x,point.y);
      CSize sz=pDC->GetTextExtent(str);
      pDC->LineTo(point.x+sz.cx,point.y);
      //assuming that a pointer to the recordset exists
      m_pSet->MoveFirst();
      while(!m_pSet->IsEOF()){
            point.y-=2*nHeight;
            //assume that there are 4 fields and all of type text
            //namely m_question,m_rank,m_grade,m_comment
            //for other datatypes, they must be converted to CString
            str.Format("%-65s%-10s%-8s%s",
                        m-pSet->m_question,
                        m_pSet->m_rank,
                        m_pSet->m_grade,
                        m_pSet->m_comment);
            pDC->TextOut(point.x,point.y,str);
            m_pSet->MoveNext();
      }
      PrintPageFooter(pDC);
      pInfo->m_bContinuePrinting=FALSE;
      pDC->SelectObject(pOldFont);
      //CFormView::OnPrint(pDC, pInfo);
}

//This function was manually added to the view class
void CMyAppView::PrintPageHeader(CDC *pDC){
      CString str;
      CMyAppDoc *pDoc=(CMyAppDoc *)m_pDocument;
      CPoint point(0,0);
      str="Quality System Self Assessment";
      pDC->TextOut(point.x,point.y,str);
      TEXTMETRIC tm;
      pDC->GetTextMetrics(&tm);
      int nHeight=tm.tmHeight + tm.tmExternalLeading;
      point.y -= nHeight;
      pDC->MoveTo(point.x,point.y);
      CSize sz=pDC->GetTextExtent(str);
      pDC->LineTo(point.x+sz.cx,point.y);
}

void CSummary::PrintPageFooter(CDC *pDC){
      CString str;
      CTime tNow;
      tNow=CTime::GetCurrentTime();
      str=tNow.Format("Dated:%A, %B %d, %Y");
      CPoint point(0,-14000);
      pDC->TextOut(point.x,point.y,str);
}


I hope this helps. Thanks and a Merry Christmas and Happy New Year to you.

Hello again! regarding this question, I have tried this approach and everything is fine except that in the print preview( and on printer) I am not controlling the number of lines per page and everything writes to the same page, overlapping. I have found some code on pagination, however unclear, but I will work on it further...and I will be purchasing a book tomorrow "Programming Microsoft Visual C++ Fifth edition which hopefully will assist me in my studies. Thanks for the sample you sent...I have studied it and understand what is going on now. I will grade on your return, since I can only do one think at a time here I believe...I can't add a comment and grade at the same time. Bye for now!
