Subject: MiniClient Error

In the miniclient example, of which I have not modified, I am having a problem, sending out and receiving chat.

I use pandion as the other client for the test. I send a chat request to the miniclient from pandion then reply back, repeat this one more time and the system breaks with the following error.

Any suggestions?

m_NetworkStream.BeginWrite(bData, 0, bData.Length, new AsyncCallback(EndSend), null);

Error

Unable to write data to the transport connection: Cannot access a disposed object.
Object name: 'System.Net.Sockets.Socket'..

Below is the block of code this is in

    /// <summary>
      /// Send data to the server.
      /// </summary>
      public override void Send(byte[] bData)
      {
      base.FireOnSend(bData, bData.Length);

      // .NET 2.0 SSL Stream issues when sending multiple async packets
      // http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=124213&SiteID=1
      if (m_PendingSend)
      m_SendQueue.Enqueue(bData);
      else
      {
      m_PendingSend = true;
      m_NetworkStream.BeginWrite(bData, 0, bData.Length, new AsyncCallback(EndSend), null);
      }
      }

Hello,

it looks like your connection got closed for some reason when you send this message.
Coud you paste your debug XML? Or track down when the object gets disposed?
Its also possible that Pandion sends message events which are not covered in the MiniClient.

this debug looks ok. Did you try to set a breakpoint in the OnMessage handler to see what happens?

Scenario

1. Start MiniClient in Debug (With breakpoint on onmessage)
2. Login to Test Account
3. Start Pandion on remote machine
4. Login to Test Account
5. Send a message from Pandion to MiniClient
6. MiniClient received ok and display message. (Incoming Breakpoint breaks correctly)
7. Send another message.
8. MiniClinet does not receive the message.
9. NO Incoming Breakpoint

I have tested the server and the accounts by putting trying two pandion clients with each account logged in and they work great.

Any suggestions?

Bryan

Subject: PS

When I try the MiniClient against the miniclient. All works

So its the communication between the MiniClient and pandion client. Seems wierd?

Can you try this and let me know. All you will need to do to reproduce is use a pandion client and the miniclient. It will error out.

Hi,

did you put a breakpoint on both message callbacks?
There is one in the main form and there is on in the message form.
I will try this scenario tomorrow myself with a pandion client. Now its nap time ;-)

Hello,

i downloaded pandion and send several messages. I had no problems.
I tried the sample source from the download page with VS 2003, and i tried the latest developer code on VS2005. Everythink ok for me.
Did you login both clients with the same user ID or with a different user ID?

Wierd!

Different ID's

I am using http://www.jivesoftware.org/wildfire/ as the server if that makes a difference.

I am using 2005 to compile the application. Hmm. . .

I will download and the latest examples and library again and test.

I was pretty sure I had the latest. But will check.

in this line: XmppCon.Show = (ShowType) Enum.Parse(typeof(ShowType), cboStatus.Text);

Can you help me? where is the problem?

Thank you

Hello,

this is a bug in the MiniClient for the offline status.
Please update the ComboBox event to the following code:

private void cboStatus_SelectedValueChanged(object sender, System.EventArgs e)
{
    if (XmppCon != null && XmppCon.Authenticated)
    {
      if (cboStatus.Text == "online")
      {
      XmppCon.Show = ShowType.NONE;
      }
      else if (cboStatus.Text == "offline")
      {
      XmppCon.Close();
      }
      else
      {
      XmppCon.Show = (ShowType)Enum.Parse(typeof(ShowType), cboStatus.Text);
      }
      XmppCon.SendMyPresence();
    }
}
