Using the Print Dialog’s Selection Button

pInfo->m_pPD->m_pd.Flags&~PD_NOSELECTED

pInfo->m_pPD->m_pd.Flags|PD_SELECTED

(PRINTDLG CPrintDialog::m_pd )

Adding Default Pagination Support

CSIZE size;

CPrintInfo pi;

if(AfxGetApp()->GetPrinterDeviceDefault(&pi.m_pPD->m_pd))

{ 

  1.   HDC hDC=pi.m\_pPD->m\_pd;
  3.   if(hDC==NULL)
  5.          hDC=pi.m\_pPD->CreatePrinterDC();
  7.   else
  9.   \{ 
  11.          CDC dc;
  13.          dc.Attach(hDC);
  15.          size.cx=dc.GetDeviceCaps(HORZRES);
  17.          size.cy=dc.GetDeviceCaps(VERTRES);
  19.          ::DeleteDC(dc.Detach());
  21.   \}

}

Enumerating Printers

#include

  1.     ![Image 1][]…

DWORD dwSize,dwPrinter;

::EnumPrinters(PRINT_ENUM_LOCAL,NULL,5,NULL,0,&dwSize,&dwPrinter);

BYTE *pBuffer=new BYTE[dwSize];

::EnumPrinters(PRINT_ENUM_LOCAL,NULL,5,pBuffer,dwSize,&dwSize,&dwPrinter);

if(dwPrinter!=0)

{ 

  1.   PRINTER\_INFO\_5 \*pPrinter=(PRINTER\_INFO\_5\*)pBuffer; // in Windows NT or Windows 2000, use PRINTER\_INFO\_4 structures instead
  3.   for(DWORD i=0;i<dwPrinter;i++)
  5.   \{ 
  7.         pComboBox->addString(i,pPrinter->pPrinterName);
  9.         pPrinter++;
  11.   \}

}

  1.     ![Image 1][]…

//a printer selected from combobox and create printerdc

CString nStrPrinterName;

int nIndex=pComboBox->GetCurSel();

pComboBox->GetLBText(nIndex,nStrPrinterName);

CDC dc;

dc.CreateDC(NULL,nStrPrinterName,NULL,NULL);
