Application.Exit After Event Fires -- dotnet windows forms

Where should I place the Application.Exit?

The current order of events are as follows:
1. the form loads using InitializeComponent (only two controls are loaded, a
button and the webbrowser control).

2. In the Form1_Shown I click the button
private void Form1_Shown(object sender, EventArgs e)
{
button1.PerformClick();
}

3. The button click event loads a url into the browser control and wires the
print event for document completed.
private void button1_Click(object sender, EventArgs e)
{
try
{
string[] args = Environment.GetCommandLineArgs();
string URL = args[1].Trim();

if (!URL.StartsWith("http://") && !URL.StartsWith("https://"))
{
URL = "http://" + URL;
}
webBrowser1.Navigate(new Uri(URL));
webBrowser1.DocumentCompleted += new
WebBrowserDocumentCompletedEventHandler(PrintDocument);

}
catch (Exception ex)
{
}
}

4. the print event fires, but IMPORTANT: the actual document does not start
printing until all these events are fired???
private void PrintDocument(object sender,
WebBrowserDocumentCompletedEventArgs e)
{
try
{
// Print the document now that it is fully loaded.
((System.Windows.Forms.WebBrowser)sender).Print();

//WebBrowserReadyState state = webBrowser1.ReadyState;
//webBrowser1.ShowPrintDialog();

// Dispose the WebBrowser now that the task is complete.
((System.Windows.Forms.WebBrowser)sender).Dispose();

//System.Windows.Forms.Application.Exit();

}
catch (Exception ex)
{
}
}

5. then the default dispose fires
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);

//System.Windows.Forms.Application.Exit();
}

6. The print job now starts? All my code is done executing when this occurs.

As you can see, I've tried calling Application.Exit in both 4 and 5 and they
are both too early. I guess what I am looking for is another event, one in
the winforms that runs after the print job has finished.

I'm sure its an easy solution, I just dont work with winforms often.

Thanks Again

There's always an easy way. Use a MessageBox to ask the user if the
document is done printing. when the user presses Yes (Ok or whatever)
execute the Application.Exit().

This is another way:
I've added a just WebBrowser and a Timer to the form. I set the
Interval property of the timer to 2000 (2 secs). My code looks like
this:

private void Form1_Load(object sender, EventArgs e)
{
this.webBrowser1.Navigate("http://www.google.com");
}

private void webBrowser1_DocumentCompleted(object sender,
WebBrowserDocumentCompletedEventArgs e)
{
this.webBrowser1.Print();
this.timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
this.timer1.Stop();
Application.Exit();
}

This works. Thank You for your help. I still wish there was a more eloquent
solution with a Print Finished event, etc. I'll have to set the timer
interval pretty high in order to guarantee the app doesn't exit before the
printing; the higher the timer value the more sluggish the application.

Thanks again
