Retrieving the Properties of a Connection (JScript)

[Internet Connection Firewall may be altered or unavailable in subsequent versions. Instead, use the Windows Firewall API.]

The following JScript code enumerates the connections on the local computer. For each connection, the code obtains a sharing configuration interface for the connection, and retrieves the properties for the connection.

    // create net sharing manager
    var objShare = new ActiveXObject("HNetCfg.HNetShare.1");

    if (objEveryColl != null) {
        varCount = objEveryColl.Count;
        if (varCount > 0) {
            // convert to built-in Java-style enumerator
            var e = new Enumerator (objEveryColl);
            e.moveFirst();
            for (; !e.atEnd(); e.moveNext()) {

                // get an INetConnection interface (not an ole-automation object)
                var objNetConn = e.item();
                if (objNetConn != null) {

                    // find the right connection, by examining the NetConnectionProps
                    var objNCProps = objShare.NetConnectionProps (objNetConn);

                        str +=   "Name: "         + objNCProps.Name +

                        // add code here; for example, to enable the firewall on a named connection:
