Hi Ann,
Of course TDNSQuery is running in TCP mode and MultiThreaded is set
to True.
Do you execute it in a separate thread context ? Because that can be the
reason of access violation. A component create / destroy should be in
same thread context.

i've an application to write, a client and a server.
i've choosen to use the HTTP protocol to enable communication through them.
Hence, i'll use the THttpServer as my server front-end.
my question is the following :
some requests may use some database stuff (SQLite). It shouldn't be
I have a similar design, but I also have a pointer to the thread in the
THttpConnection so that the connection can set a flag on the thread if the
connection is dropped before the thread has finished the work and risk using
a freed connection.
This design could serve several connections/threads

Not completely true about nullification :)
Let's say there would be a really up-to-date version of the documentation

Hello:
With POP3, there is no notion of folders or any organization of
messages. It is just reads a single file. When you said that your ISP
added a spam folder, what do you mean? Did they add this to a WebMail
application? If so, this has nothing to do with the POP3 server.
Hello Guillaume,
Until know what I use to do is to create a worker thread and send jobs
(with pointer to socket client object) and then worker send back a
message to socket thread with pointer of data to send back to client.
So all socket things is done from same thread.

hello,lists,
I have a pair of Client-Server Socket programs.When the client have finished
writing the datas,it should call the 'close()' to close the socket-end for
client.And,when the server receive the EOF coming from client,it should call
the 'close()' the close socket-end for server.Then the

Ok so you do nearly same as me. But at the end of threaded job I

What you're doing is transfering a socket from main thread
context to your work thread context.
My purpose is not the following. What i mean is executing
all the SQL stuff within the thread,
and the connection stuff within the main thread.
That's what I do with my MidWare threaded
