Hi Noam
...definitely no need to synchronize in a "single threaded app".
Multi threaded:
Main thread: Just add content to TMemo
Other threads: Use synchronize (Executes a method call within the main
thread)

Hi,
OK...
Make sense but if you have a few TWSocets running at the same time
and from every connection writing to a shared TMemo you do not
need to synchronize it somehow ?
OK, maybe my problem was different.
Thanks for elaborating this.
BR,
Noam.

Can you please explain "there is definitely no such issue" ?
I had a problem similar to this:
I had a thread sending ping's to a list of IP's to check if devices are
online.
Please read again what I said: His program isn't multithreaded.
If you use threads, then you can NOT acces any GUI item - such as a TMemo -
from your thread. VCL is not "thread safe".
I was told by a friend that the reason for that happening is that window
is not an RT OS and will time slice the operation.
This is not related at all to a real time operating system or not.
Am I missing here something ?
I don't know. Maybe you forgot that TWSocket component multitask without
using threads. It simply uses events. And as such don't need to use
synchronization objects. Of course if you use TWSocket in a thread, you are
back to the difficulties of multithreading. And you may actually built a
slower application to make a long story short.
