I have set a feature in my program that uses the Winsock control to be able to reconnect to the internet if disconnected. This is for a DUN (Dialup network) connection. How i do this is by a timer which fires every 30 secs to check if the DUN connection is still established.
This works fine BUT if the user has a Cable Modem it the program will think that since it is not connected via DUN that it is not connected to the net, however, with a cable modem you are always connected to the internet. Is there a check i can do to see if the user has ANY kind of internet connection (besides DUN) and if he/she does and the connection is lost i want to be able to pop up an error message indicating connection was lost. Thanks
