How to open a URL in a webservice

Hi,

In my infopath form, I created a submit data connection, when the form is submitted, it calls a webservice. How should I launch a webpage from this webservice.

I tried the following, but it didn't work

System.Diagnostics.Process.Start("http://www.microsoft.com/");

And then I tried the client side script: System.Web.UI.ScriptManager.RegisterClientScriptBlock, but how do I get the current control or type for its parameter?

Or should using another method?

Please advice, your help would be greatly appreciated.
