Login with webbrowser Problem

[Phipu]

Good evening together.

I want to log on the web page on http://108.hosttech.ch/user/index.php
the web browser. This is usually not a problem but I can not get the login button automatically vers / click

So far I have this;

WebBrowser1.Document.All ("user name"). SetAttribute ("value", "***********")
        WebBrowser1.Document.All ("password"). SetAttribute ("value", "************")
        WebBrowser1.Document.GetElementById ("?? Name ??"). InvokeMember (" click ")

Thanks for the help
