WebBrowser.Navigate("javascript: ... - when js code execution will end

hi
i am executing javascript code on loaded page by

Code:

---

webBrowser.Navigate("javascript: code here");

---

is there a way to notify my app that javascript code execution ended ?

Well 2 possible ways :

1) The WebBrowser.DocumentCompleted event
2) The WebBrowser.ReadyState property

well actually iam using gecko browser, i tought it will have similar properties, now i know thats not true :)
1 way - not working in both webbrowser and gecko
2 there is no readystate in gecko browser, there is isBusy but its not working either,
i was to lazy to test readystate on Webbrowser, but thx anyway
