Firing Events from Modile containing a Threads code

[Guest]

Hi

Ive been advised to use events in my app. I have a worker thread that listens for UDP packets. It converts the incoming UDP Byte array into a Packet object. This then gets placed onto a ReceivedPackets Queue. Im not too familiar with Events but need to know how to get my thread to fire the event and my form, could 1 of 9 forms, to detect that event has been fired and handle it

I know that I should use "RaiseEvent" in the Thread. The thread has been declared in a Module. How do I put it all together? I guess the forms need something like "AddHandler EventName, New EventHandler Addressof procedureToRun" but donr know how to put it all together. I tried but the Thread was complaining of an "End of statement expected" compilor error

Also, If Ive received 2 packets with a 200ms interval between them and hence the event gets fired twice, what happens? does the app wait for the first procedure to finish executing and then call the method again in response to the second event firing? Can this cause potential delay/problems in my app

Im using VB.NET but C# will suffice

Thanks.

response to the second event firing? Can this cause potential delay/problems
in my app?

I've got no idea how VB used Modules. Logically they make no sense to me,
as they don't seem to reside inside any particular class. Personally I'd
move the code to a class and make it static (Shared) if necessary. I think
that's probably all a Module is doing anyway.

Thanks Chris,

But the article doesnt mention anything about raising events from Modules.

I have a method that is declared in a module and is run in a thread
(listenForUDPPackets). I want to fire an event from the method in the Thread
and the form can handle it. Any Ideas?
