Resolved Problem programming ProgressBar into my web browser

[sega dude]

I am having a problem programming a ProgressBar into my web browser. I don't get any build errors but once the web page starts to load I get thrown an exception. http://img200.imageshack.us/img200/8923/bwexception.png This is the code im using.

Private Sub WebBrowser1_ProgressChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserProgressChangedEventArgs) Handles WebBrowser1.ProgressChanged
        ToolStripProgressBar1.Value = e.CurrentProgress
    End Sub

How do I get this to work? Why is this happening?

The issue is that the CurrentProgress is greater than the ProgressBar's maximum value. I am not sure if there is a better way or not, but this works:

Change this:

Private Sub WebBrowser1_ProgressChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserProgressChangedEventArgs) Handles WebBrowser1.ProgressChanged
    ToolStripProgressBar1.Value = e.CurrentProgress
End Sub

To this:

Private Sub WebBrowser1_ProgressChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserProgressChangedEventArgs) Handles WebBrowser1.ProgressChanged
    ToolStripProgressBar1.Maximum = e.MaximumProgress
    ToolStripProgressBar1.Value = e.CurrentProgress
End Sub

Hope this helps

I added that line of code and it gets a bit farther but now I get another exception.

Sorry, try this:

Private Sub WebBrowser1_ProgressChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserProgressChangedEventArgs) Handles WebBrowser1.ProgressChanged
    If e.MaximunProgress = -1 Or e.CurrentProgress = -1 Then Exit Sub
    ToolStripProgressBar1.Maximum = e.MaximumProgress
    ToolStripProgressBar1.Value = e.CurrentProgress
End Sub

That worked. Thank you Joshdbr. I ended up having to change the maximum value to a really high # but it works using that code.
