Question

static BOOL SetSystemProxyPacUrl( wchar_t* proxy_full_addr)

    INTERNET_PER_CONN_OPTION_LISTW list;
    BOOL bReturn;
    DWORD dwBufSize = sizeof(list);
    // Fill out list struct.
    list.dwSize = sizeof(list);
    // Set three options.

        list.pOptions[0].Value.pszValue = NULL;
    }
    DWORD ConnectedState = 0;
    LPDWORD lpdwFlags = (LPDWORD)&ConnectedState;
    char ConnectedName[4096] = {'0',};
    LPTSTR lpszConnectionName = (LPTSTR)ConnectedName;
    BOOL internetconn = InternetGetConnectedStateEx(lpdwFlags, lpszConnectionName, 4096, NULL);
    if ((ConnectedState & INTERNET_CONNECTION_LAN) == INTERNET_CONNECTION_LAN ){
        list.pszConnection = NULL;
    }else{
        list.pszConnection = lpszConnectionName;
    }
    // Set the options on the connection.
    bReturn = InternetSetOption(NULL,INTERNET_OPTION_PER_CONNECTION_OPTION, &list, dwBufSize);
    // Free the allocated memory.
    delete[] list.pOptions;
    InternetSetOption(NULL, INTERNET_OPTION_SETTINGS_CHANGED, NULL, 0);
    InternetSetOption(NULL, INTERNET_OPTION_REFRESH, NULL, 0);
    return bReturn;
