Open Print Dialog using C++

Open Print Dialog using C++ :

The following code example demonstrates how to use the PrintDialog control to set the AllowSomePages, and Document properties. To run this code you have to paste this code into some button click event.

Following header file should be include foe windows OS:


#include "windows.h"

Example Code :

void CDemo_PrintDlg::OnBnClickedPrint()
{
    BOOL            printDlgReturn = FALSE;
   HDC                printerDC = NULL;
   PRINTDLG        printDlgInfo = {0};
   LPWSTR            localPrinterName = NULL;
   PDEVMODE        returnedDevmode = NULL;
   PDEVMODE        localDevmode = NULL;
   int                localNumberOfCopies = 0;

     // Initialize the print dialog box's data structure.
    printDlgInfo.lStructSize = sizeof( printDlgInfo );
    printDlgInfo.Flags =
    // Return a printer device context.
    PD_RETURNDC
    // Don't allow separate print to file.
    // Remove these flags if you want to support this feature.
    | PD_HIDEPRINTTOFILE       
    | PD_DISABLEPRINTTOFILE
    // Don't allow selecting individual document pages to print.
    // Remove this flag if you want to support this feature.
    | PD_NOSELECTION;

    // Display the printer dialog and retrieve the printer DC.
    printDlgReturn = PrintDlg(&printDlgInfo);

   // Check the return value.
   if (TRUE == printDlgReturn)
   {
  
    // Get the HDC of the selected printer
    printerDC = printDlgInfo.hDC;
   
  
    //  Lock the handle to get a pointer to the DEVMODE structure.
    returnedDevmode = (PDEVMODE)GlobalLock(printDlgInfo.hDevMode);

    localDevmode = (LPDEVMODE)HeapAlloc(
                        GetProcessHeap(),
                        HEAP_ZERO_MEMORY | HEAP_GENERATE_EXCEPTIONS,
                        returnedDevmode->dmSize);

    if (NULL != localDevmode)
    {
        memcpy(
            (LPVOID)localDevmode,
            (LPVOID)returnedDevmode,
            returnedDevmode->dmSize);

           localPrinterName = localDevmode->dmDeviceName;

      
        localNumberOfCopies = printDlgInfo.nCopies;   
    }
    else
    {
        // Unable to allocate a new structure
    }

    //  dialog box.
    if (NULL != printDlgInfo.hDevMode)
    {
        GlobalFree(printDlgInfo.hDevMode);
    }
 }
 else
 {
     // The user cancelled out of the print dialog box.
 }
}
