Subject: can't receive callbacks when using thread on Form Application
I'm evaluating MatriX trial version (ver 1.4.4).
I had trouble when the worker thread(not UI thread) on Windows Form Application calls MatriX API.

I create worker thread from UI thread, and call connect method from the worker thread ,
then Matrix callback only "OnValidateCertificate" and "OnBeforeSasl"( not callback even OnSendXml ).

The cases,  not using thread(call connect method directly from UI thread), and not using Forms ( call from TestCase )
are successful.

Matrix trial version has any restrictions for UI application?


I attached sample project file to reproduce this problem.
If you run, please change the line(64-67) of Program.cs.

Thanks.

I can confirm that there is a problem.

In MatriX you can pass a Dispatcher objet which Matrix is using to invoke all events to make your UI thread safe. So you don't have to invoke all MatriX events because MatriX does this job already.

When you set no dispatcher manual then MatriX is using Dispatcher.CurrentDispatcher as the Dispatcher object. This fails with your threads.

Do you have an idea how you can pass a correct Dispatcher? For a test I disabled our dispatching in the code and it works fine with your threads. If we can find no other solution then I must add a property which disabled the automatic invokes in MatriX.

I also find no other quick solution.
I will add a new property as soon as I have finished teh task I am currently working on. I come back to you in this thread.

I have uploaded a new binary for the full .NET Framework to the latest builds. There is a new property AutoInvoke. When you set this to false before you call Open all your examples works fine for me.

Please let me know if this solves your problem.

Hi Alex, Yasu,

Could you guys give an example of using AutoInvoke to make multithread client work?

Thanks!

download the latest version and add the following to your code:

  1. xmppClient.AutoInvoke = false;

Hi Alex,

I've download the matriX again from http://www.ag-software.net/matrix-xmpp-sdk/download/. The new one is the same as the one I had, both of them are dated 11/4/2011 11:46 am and they do not have AutoInvoke defined (it seems that you implented it around 12/16/2011). Where to download the latest version?

Thanks!
