ICS will never actually freeze your application, though with very fast transfers it happens that the GUI freezes since Windows puts WM_PAINT messages into the message queue only when the queue is empty. So it's IMO a good idea to use a worker thread to keep your GUI responsive. In order to detect timeouts you do not need a worker thread, just use a TTimer to check whether something was received or sent in intervals. In OnProgress event you could simply set a flag which is reset in OnTimer event. -- Arno Garrels to overcome this problem I thought that I can, - Create a thread to make the ftp transfer - Assign OnProgress event, and in this event handler PostMessage to the main application window, - In main thread if message from thread does not come for long time, kill the thread and restart the uploading by creating another thread instance. Is this approach is a proper solution or what would you suggest?

Re: [twsocket] Simple SMTP text emails rejected for virus or spam
It's possible that their filter recognize the X-Mailer header,
try to remove or overwrite it in OnHeaderLine event.
Also if the mail used multiple parts the MIME boundaries could
be recognized as well. Many spammers use ICS.
Regarding the hard coded boundary strings I suggest to make
them (or parts) component properties.

Re: [twsocket] Ftp freezing
I am using tftpcli in passive mode to upload files, while uploading a file, for some reason if a connection problem occurs in the middle of the transfer, the program freezes , There is no reason inside ICS which could freeze the program since it uses async operation. Please try the same upload using FtpTst sample application delivered with ICS to see if it comes from your own coding. If it occurs with FtpTst, then do some more testing: 1) Try on several other computers 2) Check your security products such as firewall, anti malware and similar. Some are bugged and make async winsock operation blocking ! to overcome this problem I thought that I can, - Create a thread to make the ftp transfer - Assign OnProgress event, and in this event handler PostMessage to the main application window, - In main thread if message from thread does not come for long time, kill the thread and restart the uploading by creating another thread instance.

Re: [twsocket] Simple SMTP text emails rejected for virus or spam
It is likely that - despite what they say - your IP or hostname is
blacklisted.
You should try to send the email, with the exact same program, from another
computer (or even several computers) using another ISP. If the problem
happend from anywhere, then it is a problem of the mail itself. For example,
each eamil sent by ICS contains a header line X-Mailer: ICS SMTP Component
V7.26. Maybe their anti spam check that line for some strange reason. You
can easily change that lin by going into the source code.

Re: [twsocket] Async in 1GBit LAN, high CPU?
Hello Arno, 1GB networks are very difficult to tune as many hardware behind the network cards can't handle such high speed, for example hard drives on client machines usually can't handle full 1Gb speed reception and will stay at average 80-100Mb only this making different bottlenecks on the machine that could go 100% CPU when it should not. Also an other thing, if you force 10Mb or 100Mb on one side you may encouter some problem if other side is set to auto-negotiate as the other side will always try to re-negotiate to higher speed (and them produce a lot of garbage due to negotiation). regards.

Thanks for the input Francois. I have indeed tested by sending through an alternate gateway and other methods. Same problem. Also, when I attempt to reroute through a gate SMTP, my gateway SMTP logs show that the IP blockage has been removed and that the target SMTP server responds with the virus/spam error instead of host rejection. So, I think they are correct that there is no IP blockage anymore.

Re: [twsocket] Simple SMTP text emails rejected for virus or spam
Well, I finally resolved this issue. What a pain. In the end, the problem was just character data that GoDaddy didn't like. It would have been nice if their SMTP response had said something like, Invalid character data detected, instead of, Rejected due to spam or virus content. But, maybe I am asking too much? ;) Specifically, the problem was that GoDaddy doesn't like parenthesis [( and )] in the from field. I was using parenthesis to designate the email address content from the friendly name, like, Some User (u...@domain.com). I use that format so that users will see a more readable name in their mail client (Outlook, etc). Changing to brackets, like Some User u...@domain.com, fixed the problem. Go figure. Historically, I have used both and never had a problem. In this case, the SMTP profile was stored in an encrypted XML file for my service, so the was giving my problems in the beginning with the XML tags. Hence, I used parenthesis instead. Odd that GoDaddy didn't like it. I have never had a problem with that format in the from field. Oh well, like I said, a more relevant message would have saved two days of my time, as well as their tech's time. BTW, I thought this was rather indicative of GoDaddy's persona. Most servers I have had to log, respond to the SMTP data request with something like, 354 Start mail input; end with CRLF.CRLF, or something informative like that. However, GoDaddy's response is, 354 go ahead punk, make my day. Really. Kind of tells ya something, huh? :) Thanks for the input.

[twsocket] Conflicts between multiple instances
Is there a problem having multiple instances of ICS socket objects on the same thread? I have a Delphi app (single threaded) with different ICS-based objects in various units. I saw today what looked like crossover functionality between some of them. I'm getting TTimer access violation errors that only occur if I am simultaneously running a TTnCnx client in one unit and a TWSocketServer server in the other ... AND ... the errors only occur after I have made and closed a connection to the server. If the TTnCnx client is not active, I can make and break connections to the sever indefintely without any TTimer issues. If the server is not running, TTnCnx works fine indefinitely. But, if both are active and I make and break a single server connection, after a predictable amount of time (~3min) I will get repetitive TTimer access violations. Does ICS use any singletons in a thread (globals) or anything that might tie these two uses together somehow? -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
