So I am trying to use the search bar on the the face book page and I am stuck. I don't even know if Facebook allows it. This is what I am using right now. It places the text in the box, but it wont invoke the click

Code:
Try
            WebBrowser1.Document.GetElementById("q").SetAttribute("Value", txtEmail.Text) 'Fills the Search field on the website
            WebBrowser1.Document.GetElementById("Search").InvokeMember("click") 'Submits the information filled
        Catch ex As Exception

        End Try
