Hi SZ, You were right, many thanks. And modifications automatically done when opening BCB6 projects in CB2007 edi seem to work fine. Waoooh ! Regards Gerard Colo Logic Systems [EMAIL PROTECTED]

After downloading and unpacking it, I found instructions in the readme.txt file, but the topics are stopping after "CBuilder 2006". If the answer to the previous question is yes, can I apply instructions for CBuilder 2006 to CBuilder 2007 ?

I think the latest v6 beta includes a package project for it. If not, it's not a big deal to build yur own project.

I am already working with a slow server connection and the Microsoft Vista?TCP autotuning made the connection even slower, slow enough to TIMEOUT.? I wasn't?experiencing a TIMEOUT with XP.? After I disabled autotuning, chimney, and rss my application worked on Vista just as it worked on XP. (netsh interface tcp set global autotuning=disabled netsh interface tcp set global chimney=disabled netsh interface tcp set global rss=disabled) ? I do have a new question:? I could not determine if HttpCli component has a TIMEOUT property.? My current TIMEOUT implementation is as follows: ? bHttpCliBusy := True;? // This variable get set to False in HttpCli1 OnRequestDone HttpCli1.GetAsync; ? // Procedure that waits for either 30 seconds to elapse or?bHttpCliBusy=False Client1BusyTimeout(30); Is there a different way to implement a Timeout with the HttpCli1. ? Thank you. ? ------------------------------ Message: 5 Date: Thu, 19 Jun 2008 19:10:31 +0200 From: "Arno Garrels" <[EMAIL PROTECTED]> Subject: Re: [twsocket] Vista is the culprit and TIMEOUT implementation To: "ICS support mailing" <twsocket@elists.org> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset="iso-8859-1" Cyman73 wrote: > (netsh interface tcp set global autotuning=disabled > netsh interface tcp set global chimney=disabled > netsh interface tcp set global rss=disabled) Good to know, but I guess it's more a problem with older routers instead of a general Vista bug. Why did you disable tcp chimney as well, is it realy required? > I do have a new question: I could not determine if HttpCli component > has a TIMEOUT property.

And what happens on downloading a big file or when data is received very slow? It's much better to write GetTickCount() into a variable anytime something is received and let a timer check this variable, for example, every 5 seconds. -- Arno Garrels ------------------------------ Message: 6 Date: Thu, 19 Jun 2008 21:35:49 +0200 From: "Francois PIETTE" <[EMAIL PROTECTED]> Subject: Re: [twsocket] Socket throughput optimizations To: "ICS support mailing" <twsocket@elists.org> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=original >> Here are a few ideas to get high performances: >> 4) Enlarge winsock buffers >> 5) Enlarge TWSocket send buffer (BufSize property) to mach actual network >> packet size.

Memory allocation is a [relatively] slow process and tend to fragment memory which makes it even slower. Using FastMM enhance the behaviour but it is still there. Long strings and dynamic array are just dynamic memory allocation whitout naming it. Contribute to the SSL Effort.
