PrintPageEventArgs.HasMorePages Property

• Reference

Definition

In this article

Gets or sets a value indicating whether an additional page should be printed.

public:
 property bool HasMorePages { bool get[]; void set[bool value]; };

public bool HasMorePages { get; set; }

member this.HasMorePages : bool with get, set

Public Property HasMorePages As Boolean

Property Value

true if an additional page should be printed; otherwise, false. The default is false.

Examples

The following code example assumes a Button named printButton and a PrintDocument named pd have been created on a Form. Make sure the Click event for the Button is associated with the printButton_Click method and the PrintPage event of the PrintDocument is associated with the pd_PrintPage method in the example. The printButton_Click method from the example calls the Print method raising the PrintPage event, and prints the .bmp file specified in the pd_PrintPage method. To run this example, change the path to the bitmap you want to print.

Use the System.Drawing, System.Drawing.Printing, and System.Windows.Forms namespaces for this example.

private:
   // Specifies what happens when the user clicks the Button.
   void printButton_Click[ Object^ /*sender*/, EventArgs^ /*e*/ ]
   {
      try
      {
         pd->Print[];
      }
      catch [ Exception^ ex ] 
      {
         MessageBox::Show[ "An error occurred while printing", ex->ToString[] ];
      }
   }

   // Specifies what happens when the PrintPage event is raised.
   void pd_PrintPage[ Object^ /*sender*/, PrintPageEventArgs^ ev ]
   {
      // Draw a picture.
      ev->Graphics->DrawImage[ Image::FromFile[ "C:\\My Folder\\MyFile.bmp" ],
         ev->Graphics->VisibleClipBounds ];
      
      // Indicate that this is the last page to print.
      ev->HasMorePages = false;
   }

// Specifies what happens when the user clicks the Button.
 private void printButton_Click[object sender, EventArgs e] 
 {
   try 
   {
     // Assumes the default printer.
     pd.Print[];
   }  
   catch[Exception ex] 
   {
     MessageBox.Show["An error occurred while printing", ex.ToString[]];
   }
 }
 
 // Specifies what happens when the PrintPage event is raised.
 private void pd_PrintPage[object sender, PrintPageEventArgs ev] 
 {      
   // Draw a picture.
   ev.Graphics.DrawImage[Image.FromFile["C:\\My Folder\\MyFile.bmp"], ev.Graphics.VisibleClipBounds];
      
   // Indicate that this is the last page to print.
   ev.HasMorePages = false;
 }

' Specifies what happens when the user clicks the Button.
Private Sub printButton_Click[sender As Object, e As EventArgs] _
Handles printButton.Click
    Try
       pd.Print[]
    Catch ex As Exception
        MessageBox.Show["An error occurred while printing", _
            ex.ToString[]]
    End Try
End Sub    

' Specifies what happens when the PrintPage event is raised.
Private Sub pd_PrintPage[sender As Object, ev As PrintPageEventArgs] _
Handles pd.PrintPage

    ' Draw a picture.
    ev.Graphics.DrawImage[Image.FromFile["C:\My Folder\MyFile.bmp"], _
        ev.Graphics.VisibleClipBounds]
    
    ' Indicate that this is the last page to print.
    ev.HasMorePages = False
End Sub
