Re: [twsocket] THttpCli and redirected links bug - continued
I experienced the same RequestDone error and asked about it previously. I
handled it by checking de StatusCode. On a RequestDone with StatusCode = 0,
it's not the final one and more will follow. However, I seem to end up with
clients that never generate a RequestDone anymore... That means clients that
never finish, which stalls the complete download process.
I hope we can start the discussion again. Thanks.

Btw, I use C++ builder 6 too... Is this a builder-specific bug?

First, i have not read the messages you write this follow up to.
This is a follow up. I wanted to report what appears to be a
related issue to the bug in THttpCli when a link is
redirected. It seems that the RequestDone is called twice.
This has already been reported and I've implemented a work
around in my program.
If you get data together with the redirection, mabe it is not a bug that
you
get requestdone twice?
I've discovered another issue in that it doesn't seem that
the RcvdStream is being cleared. For example, when a link is
requested using THttpCli and it is redirected, there can be
garbage at the beginning of RcvdStream.
RcvdStream should only contain the document obtained from the
redirected link and nothing from the original link that
caused the redirection.
I am using the latest release version and C++Builder 6.
I have reproduced this problem in my application using this
link provided by a user:
http://net1test.rhmware.com/marketingprimer
I have worked around this issue by clearing RcvdStream when
the LocationChange event is called using:
if (HttpCli-RcvdStream) {
HttpCli-RcvdStream-Seek(0,soFromBeginning);
}
If LocationChange is triggered before you have received all the data from
first request,
maybe you should clear the stream in requestdone instead,?
By the way, I hope the above is sufficient to clear the
stream but I'm not sure that it is. If it isn't can anyone
state the correct way to clear/reset a steam? I can't find it
in the documentation.
This only sets the position in the stream, in this case to the start of
the
stream. Then when you receive data, the data is written from the start of
the stream, overwriting previous data if there are any. If you use a
TMemoryStream, you can use Clear or SetSize, this will also delete old
data.
You can also delete the stream and make a new stream.

[twsocket] SMTP server adding personalized mail headers
Hello, I need to add in a special SMTP server some headers in special mails, so that users can easy classify them with rules in their email reader. I see that many programs add headers and all are prceided with X-, like: X-Text-Classification: normal X-POPFile-Link: http://mail:8080/jump_to_message?view=4479 Is this normal / best way to do ? If so I think to have domain name in it to be exclusive. Any advice is welcome of course. -- Rgds, Wilfried http://www.mestdagh.biz -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] BgException when a tcp client application is started byanother application
Hello Francois, I found the problem by examining all the socket event handlers. You are right. It's a date time conversion function that gets an invalid environment parameter when run from another app. I think the reason madExcept didn't catch it is because BgExcept caught it? Anyway, thanks a lot! -- Best regards, Jack Wednesday, September 28, 2005, 2:36:34 PM, you wrote: BgException: EConvertError: Invalid argument to date encode You pass an invalid argument to some date encode function.

Re: [twsocket] BgException when a tcp client application is started byanother a
I think the reason madExcept didn't catch it is because BgExcept caught it? I bought MadExcept earlier this week and have been playing with it. It's really designed for applications without any try/except handlers, and misses anything already caught in that way, unless you add the function HandleException into each and every such except handler, including all components. At least that's my experience so far. But the traces it provides can be useful in locating the function causing problems. My main problem is GetHeapStatus which fails with an access violation on too many of our PCs.

In that case the best way is calling the CleanupRcvdStream method.
It's not accessible so I'm just going to use something like
HttpCli-RcvdStream-Size=0;
At the moment I'm busy to solve a problem with the SSL version.
I keep this message in evidence and I'll look into this problem asap.
Thanks. Good luck. :-)
