Hello,

Is it good manner to synchronize TidTCPServer OnConnect, onDisconnect and
OnExecute events using critical section as following:




procedure Tinterf_TCP.AserverSocketConnect(AContext: TIdContext);
begin
.........
 try
 EntercriticalSection(cs);

 Do some job in main thread

 finally
 LeaveCriticalSection(cs);
 end;

end;





procedure Tinterf_TCP.AserverSocketDisconnect(AContext: TIdContext);
begin
.........
 try
 EntercriticalSection(cs);

 Do some job in main thread

 finally
 LeaveCriticalSection(cs);
 end;

end;


procedure Tinterf_TCP.AserverSocketExecute(AContext: TIdContext);
begin
.........
 try
 EntercriticalSection(cs);

 Do some job in main thread

 finally
 LeaveCriticalSection(cs);
 end;

end;

No, because using a critical section like that is not enough to ensure
thread safety with the main thread, especially if UI components are
involved.

Use the TIdSync class instead.

What is UI component?

I have no experience with this class. How to use it in my case? For example 
I would like to log events:







procedure Tinterf_TCP.Logit(info:string);
begin

.........

end;





procedure Tinterf_TCP.AserverSocketConnect(AContext: TIdContext);
begin
.........
Logit('connect')
 end;

UI = user interface.  I was referring to any visual component.

Have you looked at the Indy documentation yet?  Also, go to
http://www.deja.com and search through the newsgroup archives, as
examples have been posted many times before.

I have posted logging examples many times before.
