saving info from CPrintDlg

Hi...
Basically I need to use CPrintDialog once to find which printer will be used.  I then want to save this info and when the next time my program is run, load this info, and then just skip (or at least not display) the CPrintDialog.
I guess I need to know what data to save and then how to use it after loading it back up.

My current code is this:


void CPrintdDlg::OnButtonPrint()
{
// TODO: Add your control notification handler code here

      
int i, i2;
BOOL truth = TRUE;      
CString string1, string2, string3;
CStdioFile cfile;
CFileException fileException;
HDC hdcPrn;

if(pstring.IsEmpty() != 0)
{
   i = MessageBox("You have not selected a file!", "Stop!",        MB_OK);
   return;
}

if ( !cfile.Open( pstring, CFile::modeRead, &fileException ))
{
   i = MessageBox("There is no such file!!!", "Error", MB_OK);
      
   TRACE( "Can't open file %s, error = %u\n",
                pstring, fileException.m_cause );
return;
}

// THIS IS THE CODE THAT NEEDS TO BE ALTERED
CPrintDialog *printDlg = new CPrintDialog(FALSE,PD_ALLPAGES | PD_NOPAGENUMS | PD_HIDEPRINTTOFILE | PD_NOSELECTION);

printDlg->DoModal();

hdcPrn = printDlg->GetPrinterDC();
  if (hdcPrn != NULL)
  {
      CDC *pDC = new CDC;
      pDC->Attach (hdcPrn);      // attach a printer DC
      TEXTMETRIC tm;
      pDC->SetMapMode(MM_TEXT);
      pDC->GetTextMetrics(&tm);
     int width1 = pDC->GetDeviceCaps (PHYSICALWIDTH);
//     int vertical1 = pDC->GetDeviceCaps(VERTSIZE);
    vertical1 = pDC->GetDeviceCaps(PHYSICALHEIGHT);
    int paper_length = vertical1 / (tm.tmHeight     + tm.tmExternalLeading);
    int paper_width  = width1 / tm.tmMaxCharWidth;

    i = 0;

    pDC->StartDoc(pstring);     // begin a new print job




   while(truth == TRUE)
   {
        pDC->StartPage();          // begin a new page
        i = 0;
        string1.Empty();
        string2.Empty();
                  string3.Empty();
                  while( (i<paper_length-4) && (truth == TRUE) )
                  {
                        i++;
                        string2.Empty();
                        
                        if(string3.IsEmpty() == 1)
                              truth = cfile.ReadString(string2);
                        else
                        {
                              string2 = string3;
                              string1.Empty();
                              string3.Empty();
                        }
                        i2 = string2.GetLength();



                        if(i2 < paper_width-2)
                        {
                              pDC->TextOut(0, (i*(tm.tmHeight+tm.tmExternalLeading)), string2);// write the string in pbuf
                              string3.Empty();
                        }
                        else
                        {
                              
                              string1 = string2.Left(paper_width-2);
                              string3 = string2.Right(string2.GetLength() - paper_width+2);
                              

                              pDC->TextOut(0, (i*(tm.tmHeight+tm.tmExternalLeading)), string1);// write the string in pbuf

                        }
                        
                  }

                  pDC->EndPage();            // end a page

            }


        pDC->EndDoc();             // end a print job
        pDC->Detach();             // detach the printer DC
        delete pDC;
            delete printDlg;
      
      }

What you need to save are three strings,

1. the name of the currently selected printer driver, CPrintDialog::GetDriverName();
2. the name of the currently selected printer device, CPrintDialog::GetDeviceName();
3. the name of the currently selected printer port, CPrintDialog::GetPortName().

I suggest you save them into a INI file by using ::WritePrivateProfileString() or CWinApp::WriteProfileString().

The next time, you can read the three strings from the INI file and call the following function to create the printer DC.
BOOL CDC::CreateDC( LPCSTR lpszDriverName, LPCSTR lpszDeviceName, LPCSTR lpszOutput, const void FAR* lpInitData );
Then you can use the DC to print as you have done.
