Check Internet connection, prompt dial-up dialog. Pls Help!

[sleepyant]

Hi, I've posted this question on several forum but have no response. So I
hope anyone who have any idea what I'm talking about please give your
solution or advice.

My problem is I need to check the internet connection and pop-up a Dial-Up
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
----------------> prompt for Dial-Up dialog 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. Your help is much
appreciated. Thanks.

Process.Start("rundll32.exe", "shell32.dll,Control_RunDLL ncpa.cpl,,0");

This will open the "Network Connections" control panel. This is not exactly
dial-up dialog but at least it's one step closer :)

Thanks all. Appreciate your help. If I use "wininet.dll", do I need to
distribute "wininet.dll" together in my application setup? Or it is already
exist in existing windows OS and won't have any 'dll hell' issue? Thanks
again.

Paul, I copied the code from the link you provided and tried it out. It did
successfully detect if a connection was there or not, but failed on the following
line:
x = Shell("rundll32.exe rnaui.dll,RnaDial",
AppWinStyle.NormalFocus, False)

I did a search for rundll32.exe and rnaui.dll , neither file exists on my XP
machine. Since DUN does work on this machine, I can only assume that these items
are replaced with other files in XP. So the question becomes then, what command
should be substituted for this line to work with XP-SP2?

Thanks, and that did work. I had to use the coding version that included username and
password, otherwise the connection immediately hung up. Step one in replacing DUN GUI
