I have a big snow today, and time is really fast, I'm going to work, I have to go to work in a few days.
API: InternetGetConnectedState
DeconnectedState Lib "Wininet" (Byval CONNECTIONDESCRIPTION AS INTEGER, BYVAL TMP AS INTEGER) AS Boolean
BConnect = InternetGetConnectedState (0, 0)
I now use my mobile phone dial-up test to check the status correctly. How is the situation connected to the LAN after work?
