Help onThreading and RaiseEvent ????

[Serge Calderara]

Dear all

I have an assembly named Comm.dll which is in charge of handling tcp communication. Inside that assembly I have function which is pooling every 500ms the TCP port for incoming data. That function as been place in a thread that we could named TH1
When data has been detected on TCP port, TH1 raise an event named DataArrive

Then I have a main application window which refer to that comm.dll assembly and whcih has a delegate function responding the DataArrive event raise by TH1. We will call that delegate function GetDataFromTh

When GetDataFromTh1 is called, I process the incoming data and depending of the arrive data I raise en event named DataProcessed inside that delegate function name

Doing this, it gets my all system hanging. Only the mouse is working.

The question is : do we have the right to raise an event in a delegate which is raise in a different thread.

WHat is really happenning and is there any other solution

Reagrds and thanks for your hel
