Hello Widita,
Those access violations never happened when LineMode is false...
Does anyone know the solution for this problem?
LineMode True or False has on itself nothing to do with AV. So on base
on this information nobody can give solution. There is something wrong
with your code but
Hello!
Yes, I'm going to use such long delimiter because I need to send binary
data...
If you're sending binary data, don't play with delimiters, but send the
data size first (as a 4-byte longint), then actual data. Client first waits
for data size, then waits for the data_size bytes and
WSocket will always trigger exactly one OnDataAvailable per line received.
Is this completely true. I'm sure in the past I've had a receive call
return multiple lines, something like This is one line'#13#10'this is the
next'#13#10'. And I had to split multiple lines, and process
so I can't call application.processmessages at all?
what can I call if I need my user interface updated? for example I changed a
Label's caption and need it refreshed when accepting data?

Sure you can, but not from an event handler or you'll have problem reentering

I want to ask about line mode again,
You're welcome :-)
Is it right that in Line mode:
- DataAvailable will only be called when the data
received contains delimiter.
Right.
- DataAvailable could be called containing more than one line at a
time, we must splitting each line

Hello Widita,

But your protcol will fail if this string is in the binary data you
send. Dont tell me the chance is low. Think on Murphy's law: if it is
possible then it will happen.

Hello Wilfried,
But you also could create a delimiter #00#00 and search if exists in
you data, then try #00#01 ... then #00#02 and if you reach #FF#FF add
a third delimiter #00#00#00, #00#00#01, #00#00#02 ... until you
finally found a delimiter that do not exists.
Of course this is not a really

Can I send directly everytime I call the client.Send(@sf, sizeof(sf))?
Does TWSocketServer have any property that allow me to send everything
without buffered first?

Yes, but pay attention to dynamic data which is represented by pointers.
Sending a pointer to a remote site is useless !
Dynamic data are long strings, objects,

What do you mean by buffering first ?

Yes and no :-)

Hello Surabaya,
if you send binary with LineMode there are many way to manage it.
The simplest : use BASE64 e-mail attachement style that is nice as
designed to work ascii lined mode but increase size of data about
+40% (as all binary e-mail attachements do by the way).
You could
