Ejemplos

En el ejemplo de código siguiente se muestra cómo usar el PrintDialog control para establecer las AllowSomePagespropiedades , ShowHelpy Document . Para ejecutar este ejemplo, pegue el código siguiente en un formulario que contenga un PrintDialog control denominado PrintDialog1 y un botón denominado Button1. En este ejemplo se requiere que el evento del Click botón y el PrintPage evento de docToPrint se hayan conectado a los métodos de control de eventos definidos en este ejemplo.

// 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 )
         System::Windows::Forms::MessageBox::Show(  "null" );

   ;
   ;
   if ( PrintDialog1 == nullptr )
         System::Windows::Forms::MessageBox::Show(  "pnull" );

   ;
   ;
   System::Windows::Forms::DialogResult result = PrintDialog1->ShowDialog();
   System::Windows::Forms::MessageBox::Show( result.ToString() );
   ;
   ;
   
   // If the result is OK then print the document.
   if ( result == ::DialogResult::OK )
   {
      docToPrint->Print();
   }

}

// The PrintDialog will print the document
// by handling the document's PrintPage event.
void document_PrintPage( Object^ /*sender*/, System::Drawing::Printing::PrintPageEventArgs^ e )
{
   // Insert code to render the page here.
   // This code will be called when the control is drawn.
   // The following code will render a simple
   // message on the printed document.
   String^ text = "In document_PrintPage method.";
   System::Drawing::Font^ printFont = gcnew System::Drawing::Font( "Arial",35,System::Drawing::FontStyle::Regular );
   
   // Draw the content.
   e->Graphics->DrawString( text, printFont, System::Drawing::Brushes::Black, 10, 10 );
}

// Declare the PrintDocument object.
