How to inject Javascript in WebBrowser control?

Question

I\'ve tried this:

string newScript = textBox1.Text;
HtmlElement head = browserCtrl.Document.GetElementsByTagName(\"head\")[0];
HtmlElement scriptEl = browser         


        

Answer 1

If you need to inject a whole file then you can use this:

With Browser.Document
   Dim Head As HtmlElement = .GetElementsByTagName("head")(0)
   Dim Script As HtmlElement = .CreateElement("script")
   Dim Streamer As New StreamReader()
   Using Streamer
       Script.SetAttribute("text", Streamer.ReadToEnd())
   End Using
   Head.AppendChild(Script)
   .InvokeScript()
End With

Remember to import System.IO in order to use the StreamReader. I hope this helps.
