Description
This function attempts to make a connection to the internet if there is no connection available.
Internet Explorer < v5 only reports the status of the default Internet connectoid. If a nondefault connectoid is connected, InternetGetConnectedState always returns FALSE (unless a LAN connection is used).
On Windows Vista and later it is recommended that you call INetworkListManager::GetConnectivity() instead.
