text changed event keeps firing?

I am having trouble to stop a textchanged event from firing. I have a timer that controls part of the code but the part that fires the event is not. Why would something like this happen and if possible how can I make sure the event only fires once per text changed and not constantly?.

thank you in advance


this code is within a timer control but how or what can i do to update the textbox without using a timer? the textchanged event only fires when newly added text is added of course but it is added by the timer checking the webbrowser control in intervals of 500ms.

Dim allelem As HtmlElementCollection = WebBrowser1.Document.All
       For Each webelem As HtmlElement In allelem
           If webelem.GetAttribute("id") = "div" Then
               Dim logtext As String = webelem.InnerText
               Dim loghtml As String = webelem.InnerHtml
               RichTextBox1.Text = logtext
               RichTextBox2.Text = loghtml
           End If
       Next
