how can i have my program click a button in browser page using the browser control. I want to do this but can't find a solution.  anyone have any ideas?

Example:  have text box in a windows form with a submit button on the windows form.  When you fill in a search term in the text box, click on the submit button, the windows form should open up google in a web browser control and show the results, but actually use the google homepage to do so, not the google api.

Here is how to do it with the WebBrowser control embedded on yor form in VB.Net 2005:

Public Class Form1

    Private firstPage As Boolean = True

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        firstPage = True
        WebBrowser1.Navigate("www.google.com")
    End Sub

    Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        If firstPage Then
            firstPage = False
            WebBrowser1.Document.All.Item("q").InnerText = TextBox1.Text
            WebBrowser1.Document.All.Item("btnG").InvokeMember("Click")
        End If
    End Sub

End Class

so my understanding is that btnG is the name of the submit form.  If the forms button name is random, would this still be possible?
