After that my application can't get information from clients, clients can connect, but AThread->Connection->ReadStream(mems, -1, true) can read nothing! I recompiled with old indy9 pack and got good result. What is the difference?

You are specifying true for the AReadUntilDisconnect parameter. There is a bug in the current snapshot where ReadStream() does not exit properly when the connection is closed. It keeps looping. Inside of ReadStream(), change this code: if not (E is EIdConnClosedGracefully) or not AReadUntilDisconnect then begin raise; end; To this: if (E is EIdConnClosedGracefully) and AReadUntilDisconnect then begin Break; end else begin raise; end; Gambit Back to top Vladimir Zhuchko Guest Posted: Sun Aug 06, 2006 1:22 am    Post subject: Re: Trouble with the Last Indy9v with the CB6 vs. old Indy9 Remy Lebeau (TeamB) wrote: Quote: "Vladimir Zhuchko" <zhuchko (AT) jinr (DOT) ru> wrote in message news:44d48b8a$1 (AT) newsgroups (DOT) borland.com...

I tested this, now the application isn't freezing, but ReadStream does not working yet. I returned to the old version.

Gambit The problem is simple, before changes the application was frozen within this function (ReadStream), but after application is working, but ReadStream reads nothing.

Quote: No, not so. After recompiling of the project with the old indy9 ReadSream is working well! The only way for EIdConnClosedGracefully to be thrown is for the socket to have returned 0 bytes received during the loop. Since the loop also writes all pending data to the output stream, there is no way for ReadStream() not to return all available data when a disconnect occurs. If you look at the source code for ReadStream() in Indy 9 and 10, they are virtual identical. Your problem has to be elsewhere. So again, I ask you to provide SPECIFIC DETAILS about what EXACTLY you think is not working properly.
