Check internet connection, pop up dial-up networking dialog

[sleepyant]

Hi, how can I check the internet connection and pop-up a Dial-Up Networking
dialog when there isn't any?

I've tried the following:

Dim myReq As HttpWebRequest
Try
myReq = WebRequest.Create("http://www.yahoo.com/")
myReq.GetResponse()
Catch ex As Exception
----------------> pop up Dial-Up network here
End Try

The checking part is ok so far. But it can't automatically dial up or prompt
for dial up.
I need your advice on the correct way in doing this stuff. Thanks.
