Exempel

Följande kodexempel visar hur du använder PrintDialog kontrollen för att ange AllowSomePagesegenskaperna , ShowHelpoch Document . Om du vill köra det här exemplet klistrar du in följande kod i ett formulär som innehåller en PrintDialog kontroll med namnet PrintDialog1 och en knapp med namnet Button1. Det här exemplet kräver att knappens Click händelse och PrintPage händelsen docToPrint för har anslutits till de händelsehanteringsmetoder som definierats i det här exemplet.

// Declare the PrintDocument object.
System::Drawing::Printing::PrintDocument^ docToPrint;

// This method will set properties on the PrintDialog object and
// then display the dialog.
void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   // Allow the user to choose the page range he or she would
   // like to print.
   PrintDialog1->AllowSomePages = true;
   
   // Show the help button.
   PrintDialog1->ShowHelp = true;
   
   // Set the Document property to the PrintDocument for 
   // which the PrintPage Event has been handled. To display the
   // dialog, either this property or the PrinterSettings property 
   // must be set 
   PrintDialog1->Document = docToPrint;
   if ( docToPrint == nullptr )

   // If the result is OK then print the document.
   if ( result == ::DialogResult::OK )

Kommentarer

När du skapar en instans av PrintDialoganges läs-/skrivegenskaperna till initiala värden. En lista över dessa värden finns i PrintDialog konstruktorn. Om du vill hämta skrivarinställningar som har ändrats av användaren med PrintDialoganvänder du PrinterSettings egenskapen .

Mer information om hur du skriver ut med Windows Forms finns i översikten System.Drawing.Printing namnområde. Om du vill skriva ut från ett Windows Presentation Foundation program läser du namnområdet System.Printing.
