// Function:  SetInetStateConnected

// Synopsis:  Sets the Inet Option to tell wininet that we are connected.
//            Normally this isn't an issue but if the user has IE set to offline
//            mode, then cmdl cannot get use the wininet APIs to make a
//            phonebook request.  Thus, we will tell Wininet we are connected.
//
// Arguments: HINTERNET hInternet - inet handle to call InternetSetOption on.
//
// Returns:   Nothing
