Dim req As HttpRequest         'Set up an http request connection
  
	Dim hc As HttpClient
	Dim PostUrl As String ="http://www.google.com"

    hc.Initialize("")
	req.InitializeGet(PostUrl)

    hc.Initialize("hc")
	hc.Execute(req, 1)

	Wait for hc_ResponseSuccess (Response As HttpResponse, TaskId As Int)         'We got connection and data !!

	Dim resultString As String
	resultString = Response.GetString("UTF8")   'This holds the returned data
    
	Dim wb As WebView
	wb.Initialize("")
	wb.LoadHtml(resultString)
	Response.Release
	Activity.AddView(wb,0,0,100%x,100%y)
