Its not locked, I have the mechanisms in place to take care of deadlocks. The problem i had before was the main thread was doing the reading of messages that it hangs the UI. nonetheless thanks for replying to my question. ^^

Ok I put the message processing in the thread and it works better now. I still have to put that silly sleep statement though... by the way, there are several messages. 1 of them comes in at 1Hz while the other at 4Hz i tried sleep(50) only the one sending at 4Hz shows up, i put sleep(500) it works ok, but am missing some messages for the 4Hz, which is not much of a problem but I am curious is there a optimum sleep time to put in my case?

i tried that before, the user interface hangs there.

ok, i understand, so i should code in such a way that processing of the message is done in the thread while the main thread(mfc) should just receive the message and display only?

you mean the ReadData is not on the main thread?

roger that, sorry for the insufficient data

thanks for your answer andrew,
i put in the serial reading timeout and removed the sleep statement and put in some crt check statements (before the delete msgblk and new msgblk). This resulted in the program crashing straight away, just before the delete msgblk at the CRT check.

how do you do that? sending and receiving in a thread

Zsefv2 27-Oct-11 22:31pm View

thanks for the reply, thats what i did to fix the problem. Totally removed the serial com operations from the GUI thread and put them on the thread I spun.

can some kind soul put some code here so i can refer etc?

Zsefv2 26-Oct-11 22:11pm View

ok, i spin up a thread then suspend it, then when the event of data arrives on the com port, i resume the thread. is that it? then what if another set of data arrives on the com port? the thread would still be running?

Zsefv2 24-Oct-11 8:22am View

hmmm, let me get you, so in the initialization phase i startup the receive thread then suspend it? so on data arrived i resume it?

what do u mean by letting the thread use WaitCommEvent? are there examples i can follow?

Zsefv2 24-Oct-11 8:20am View

yeah the mutex was actually it was not there at the beginning... the shared data being the list control?

Zsefv2 19-Sep-11 23:19pm View

ok thanks...
