Disabling the notification window in the WebBrowser control

Question

I am using VS 2005 and the WebBrowser control. When I use the component to go to the specified page, I get a script error, for example, "JavaScript script error on this page" and two buttons: yes or no execution script. How to prevent warning windows and continue browsing without these messages?

Answer 1

Try

WebBrowser1.ScriptErrorsSuppressed = true; 

Answer 2

try it

 HtmlElement head = WebBrowser1.Document.GetElementsByTagName("head")[0]; HtmlElement scriptEl = WebBrowser1.Document.CreateElement("script"); IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement; string alertBlocker = @"window.alert = function () { }; window.confirm=function () { };"; element.text = alertBlocker; head.AppendChild(scriptEl); WebBrowser1.ScriptErrorsSuppressed = true;

  Private Sub WebBrowser1_StatusTextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles WebBrowser1.StatusTextChanged On Error Resume Next Dim head As HtmlElement = WebBrowser1.Document.GetElementsByTagName("head")(0) Dim script As HtmlElement script = WebBrowser1.Document.CreateElement("script") script.SetAttribute("type", "text/javascript") Dim alertBlocker As String = "window.alert = function () { }; window.confirm=function () { }; " script.SetAttribute("text", alertBlocker) head.AppendChild(script) End Sub
