Examples

The following code example demonstrates how to use the PrintDialog control to set the AllowSomePages, ShowHelp, and Document properties. To run this example, paste the following code into a form that contains a PrintDialog control named PrintDialog1 and a button named Button1. This example requires that the button's Click event and the PrintPage event of docToPrint have been connected to the event-handling methods defined in this example.

// 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.
private System.Drawing.Printing.PrintDocument docToPrint = 
    new System.Drawing.Printing.PrintDocument();

// This method will set properties on the PrintDialog object and
// then display the dialog.
private 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;

    DialogResult result = PrintDialog1.ShowDialog();

    // 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.
private 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 = new System.Drawing.Font
        ("Arial", 35, System.Drawing.FontStyle.Regular);

    // Draw the content.
    e.Graphics.DrawString(text, printFont, 
        System.Drawing.Brushes.Black, 10, 10);

Remarks

When you create an instance of PrintDialog, the read/write properties are set to initial values. For a list of these values, see the PrintDialog constructor. To get printer settings that are modified by the user with the PrintDialog, use the PrinterSettings property.

For more information about printing with Windows Forms, see the System.Drawing.Printing namespace overview. If you want to print from a Windows Presentation Foundation application, see the System.Printing namespace.
