Subject: Creating and configuring a new conference room
Hi,
I am trying to create and configure a new conference room, so it'll be persistant and logged, with max 100 users.
I have tried to use both CreateReservedRoom and JoinRoom, but none worked.

This is my code:

            MucManager muc = new MucManager(xmppCnn);

            //muc.CreateReservedRoom(roomJid);

            muc.JoinRoom(roomJid, "a");

            muc.GrantOwnershipPrivileges(roomJid, xmppCnn.MyJID);

            Field f_form = new Field(FieldType.Hidden);
            f_form.Var = "http://jabber.org/protocol/muc#roomconfig";
            f_form.Value = "FORM_TYPE";

            Field f_persistent = new Field(FieldType.Boolean);
            f_persistent.Var = "muc#roomconfig_persistentroom";
            f_persistent.Value = "1";

            Field f_log_msgs = new Field(FieldType.Boolean);
            f_log_msgs.Var = "roomconfig_enablelogging";
            f_log_msgs.Value = "1";

            Field f_max_users = new Field(FieldType.List_Single);
            f_max_users.Var = "muc#roomconfig_maxusers";
            f_max_users.Value = "100";

            Data data = new Data(XDataFormType.form);
            data.AddField(f_form);
            data.AddChild(f_persistent);
            data.AddChild(f_log_msgs);
            data.AddChild(f_max_users);

            agsXMPP.protocol.x.muc.iq.owner.OwnerIq oIq = new agsXMPP.protocol.x.muc.iq.owner.OwnerIq(IqType.set, roomJid);
            oIq.Query.AddChild(data);
            xmppCnn.Send(oIq);

Also, I have managed to RequestConfigurationForm, but I couldn't edit the query's children nodes (only added another line with diff. value), and submitting it didn't work.

Will appreciate any help,
-Dan

You should create the room with JoinRoom first. Then wait until you get presence from the room.
After you got presence and no errors you can assume that the room is created.

Then use RequestConfigurationForm to request the configuration form. Fill out the form and send it back to the server.
You have to send all fields, not only a diff. In agsXmpp.Ui there is a xdata control which handles this for you. You can either use this control, or study the code and create you own control or forms.

I can't seem to get it to work.
Here is the full info:

My code (sorry for the lame string replaces - a temporary solution)
            MucManager muc = new MucManager(xmppCnn);
            muc.JoinRoom(roomJid, "a");

            //...
            //...wait for presence...
            //...

            IQ configForm;

            muc.RequestConfigurationForm(...);

            //... getting response, placing the response IQ in variable configForm.

            //replacing the default room settings XML (temporary string replacing solution)
            configForm.Query.InnerXml = configForm.Query.InnerXml.Replace("var=\"muc#roomconfig_maxusers\" type=\"list-single\"><value>30","var=\"muc#roomconfig_maxusers\" type=\"list-single\"><value>100");
            configForm.Query.InnerXml = configForm.Query.InnerXml.Replace("var=\"muc#roomconfig_persistentroom\" type=\"boolean\"><value>0", "var=\"muc#roomconfig_persistentroom\" type=\"boolean\"><value>1");

            xmppCnn.IqGrabber.SendIq(configForm, GeneralIQHandler);

            muc.LeaveRoom(roomJid, "a");



The "fixed" XML sent at xmppCnn.Send:
- <iq xmlns="jabber:client" from="atest_m58_199@conference.danpc" to="dannntesttt@danpc/agsXMPP" type="result" id="agsXMPP_5">

Am I doing anything wrong?
should I change something else in the config-form before I submit it?

Thanks for your help,

No response is received, which is strange.

your string replace cannot work because you have to create a new Iq which is totally different.
Please look at the component I suggested and XEP-0004 which shows you how to deal with xdata forms.

Sorry, I have looked both at XEP-0004 specification, and on agsxmpp.ui, and I still cant get it to work.

XEP-0004 deeply describes XMPP protocol for this method, but not how to execute it with agsXMPP.
And about the agsXmpp.ui component, to edit a config form it display it in ui, and then builds the config form again from the UI form - I'm working on a server process, and there must be a faster way to edit the xml.

Once I have the config form IQ, what are the 2-3 commands I need to execute in order to change a setting and resubmit?

Anyway, I see that this question was already asked several times on this forum - never with a working code example.
Will it be possible to get a simple code example on configuring a new conference room?

When you request the configuration form then you get a result like this:
  1. <iq from='test2@conference.ag-software.de' to='...' id='agsXMPP_23' type='result'>
  2.     <query xmlns='http://jabber.org/protocol/muc#owner'>
  3.         <x xmlns='jabber:x:data' type='form'>
  4.             <!-- form content is here -->
  5.         </x>
  6.     </query>
  7. </iq>

Then you process the form, fill it out, and send it back in a new Iq with a new id of type set to the room. It doesn't matter if you process the from with a Ui or not. The result is always the same.

  1. <iq id="agsXMPP_24" to="test2@conference.ag-software.de" type="set">
  2.     <query xmlns="http://jabber.org/protocol/muc#owner">
  3.         <x type="submit" xmlns="jabber:x:data">

On Success you to get a response of type result with the same id as your request.
  1. <iq from='test2@conference.ag-software.de' to='...' id='agsXMPP_24' type='result'>
  2.     <query xmlns='http://jabber.org/protocol/muc#owner'/>
  3. </iq>
Here is a small code example:
  1. private void SendRoomConfig()
  2. {
  3.     agsXMPP.protocol.x.muc.iq.owner.OwnerIq oIq = new agsXMPP.protocol.x.muc.iq.owner.OwnerIq();
  4.     oIq.Type = IqType.set;
  5.     oIq.To = new Jid("room1@conference.ag-software.de");
  6.  
  7.     agsXMPP.protocol.x.data.Data xForm = new Data();
  8.     xForm.Type = XDataFormType.submit;
  9.     /*
  10.         add more code here to fill out all fields in the form.
  11.     */
  12.     oIq.Query.AddChild(xForm);
  13.  
  14.     XmppCon.IqGrabber.SendIq(oIq, new IqCB(OnRoomConfigResult));
  15. }
  16.  
  17. private void OnRoomConfigResult(object sender, IQ iq, object data)
  18. {
  19.     if (iq.Type == IqType.result)
  20.     {
  21.         // success   
  22.     }
  23.     else if (iq.Type == IqType.error)
  24.     {
  25.         // error
  26.     }
  27. }
