Hi,
I'm developing a new app.
I'm using threads, I have used it before, but I'm not sure of some
issues when threading as I'm not an expert with this.
I'll go with a direct example of what I'm doing, I know that is not
very correct, but it's the only way I know, so if someone knows how to
do it better, please tell me.

When I click some button i create a new thread:

private sub button1_click(.....)
t=new thread(addressof listenevents) ' t is a global variable
end sub

public sub listenevents
while true
' here is code of a socket listening to a port and processing all
received data
end while
end sub

When I want to stop the socket listener, in other button I have this:

private sub button2_click(.....)
t.suspend()
end sub


The problem is that I know that this method is deprecated, so I suppose
it's not the correct way of doing this code, can anybody help??
Thanks
 
Hello Jordi,

What kind of behavior are you looking for here? Do you want to essentially
end the thread permanently? If so then use the .Abort() sub to end the thread.
 
The problem is that inside the infinite loop of the thread, as the
socket stops the execution until it receives some data from the port,
if I make a thread.abort() I receive an exception from the socket, 'cos
it stops in a wrong way...
I've found that if I make a disconnect from the socket, I can execute
the next statement inside the loop and find if the socket has
disconnected, so I can know if I have to end the loop.
I've passed through this immediate problem this way, but I'll have to
find a good tutorial about threads to learn more about them...
Thanks
