I am writing a smart client application that needs to monitor the users
dial-up connection status. If the user disconnects, I need to prompt them to
reconnect, or quit the application. I tried using the following WMI query

wmiDialupDisconnect = New ManagementEventWatcher("SELECT * FROM
MSNDIS_NotifyAdapterRemoval")

but it does not work. Does anyone have any ideas how I can monitor a users
dial-up connection status?
 
Hi,

I do not know about achieving this from WMI, I am sure it can be done. From
the windows API you should take a look at RasDial, RasEnumConnections and
RasConnectionNotification, these should provide the functionality you are
looking for,

Hope this helps

Hi bradley,

Based on my understanding, you want to monitor the internet connection
status of certain system.

We may use InternetGetConnectedState WIN32 API to get the internet
connection status, for more information, please refer to:

present on the local machine"
