Hello,
I am developing a software which communicates over the CAN network. It
has a thread to transmit and another to receive the messages. After
sending some messages the transmit thread holds till it receives a
response from the network. Also the messages trans/received have to be
displayed on the GUI in real time.

For holding the transmit thread, I am using AutoResetEvent.Wait()
When the response is received I am using AutoResetEvent.Set()

For Displaying the messages in real time i am using Virtual ListView
for updating the GUI.

Now the transmit thread sometimes does not recognise that a message is
received, even when the AutoResetEvent is Set.

I think the problem is due to processing of Display and the processing
of AutoResetEvent. I think both the messages for display and autorest
are put in the message queue of the OS, which will process them
sequentially. If the display takes more time to update then the
processing of autoresetevent will take more time.

Is there any solution to this problem?
I think i need to look ahead at two fronts
1. Either change the way i update the GUI with the messages, so that i
may have to change to something other than Virtual ListView
2. Or Find some other way to unblock the transmit thread when i
receive the message.

Please help.
Thanks in advance.

If the transmit and receive never run at the same time, why do you use
separate threads?
