Adding Default Pagination Support

CSIZE size;

CPrintInfo pi;

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

{

      HDC hDC=pi.m_pPD->m_pd;

      if(hDC==NULL)

             hDC=pi.m_pPD->CreatePrinterDC();

      else

      {

             CDC dc;

             dc.Attach(hDC);

             size.cx=dc.GetDeviceCaps(HORZRES);

             size.cy=dc.GetDeviceCaps(VERTRES);

             ::DeleteDC(dc.Detach());

Enumerating Printers

#include<winspool.h>

        …

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)

{

      PRINTER_INFO_5 *pPrinter=(PRINTER_INFO_5*)pBuffer; // in Windows NT or Windows 2000, use PRINTER_INFO_4 structures instead

      for(DWORD i=0;i<dwPrinter;i++)

      {

            pComboBox->addString(i,pPrinter->pPrinterName);

            pPrinter++;

      }

}

        …

//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);
