If Printer Dialog Cancelled, Then Don't Print?

Question

If I run this code, and press cancel on the PrintDialog, it still prints. How can I tell if the use pressed cancel?

PrintDocument document = new PrintDocument();
PrintDialog dialog = new PrintDialog();

dialog.ShowDialog();
document.PrinterSettings = p.PrinterSettings;
document.Print();

Addendum

WebBrowser w = new WebBrowser();
w.ShowPrintDialog(); //.ShowPrintDialog returns a void, how can I deal with this?

You can check the result of the ShowDialog method:

if (dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
   //Print
}

What can I do with WebBrowser.ShowPrintDialog? It returns a void and not a DialogResult. – sooprise Feb 15 '11 at 18:55

ShowDialog returns a dialog result enumeration. It will either be OK, or Cancel.

PrintDocument document = new PrintDocument();
PrintDialog dialog = new PrintDialog();

if(dialog.ShowDialog() == DialogResult.Ok)
{
    document.PrinterSettings = p.PrinterSettings;
    document.Print();
}

Unfortunately I don't thing there is a way to handle this. What would you like to do with the result? i.e. if the dialog was cancelled, what code would execute? – Craigt Feb 16 '11 at 05:49

The answers above are correct for System.Windows.Forms.PrintDialog. However, if you're not building a Forms application, the PrintDialog you will use is System.Windows.Controls.PrintDialog. Here, ShowDialog returns a bool?:

var dialog = new System.Windows.Controls.PrintDialog();

if (dialog.ShowDialog() == true)
{
    // Print...
}

If Printer Dialog Cancelled, Then Don't Print?
