[twsocket] From Fastream and Dod to List: ICS Server/client TCP proxy failing to obeying Windows log off
Hello, My code at http://www.fastream.net/alpha/SecureTunnelClient.zip -according to Dod- causes problems when run for days on Gmail when windows tried to log off. I have no clue what is wrong as it does not occur on my Win Vista x64. The only special thing about the code is the tray icon but that does not seem to be related at all. He is using Win2000. Any idea?

Already done last week. However Digest is more similar to Basic, the only difference to Basic is that at least one challenge is required to build the Authorization header line. The key is the PrepareNextStep method where the class receive the header line to get all information needed and set the required properties. With digest you would have to parse the server challenge at this point, and check whether it is syntactically correct and reset the nounce count (nc) value/property to zero. For each subsequent Authorization header which is created using the _same challenge the nc has to be incremented by one. Problem is however that if a proxy sends 407 after you already got a server challenge the Autorization header was not received by the server so next time the Autorization header is created the nc must not be incremented otherwise the server may see gaps nc=0001, nc=0003 etc (this is currently no problem since a challenge is not yet reused). [...] Also see my latest changes in the ICS v7 repository. I'll do that but first I must change how the component works. Will you be adding your changes to v7?

Re: [twsocket] breakpoint in NTDll
Wilfried said... NTdll.DBGBreakPoint int 3 ret What OS and version? I can't remember exactly what version it was, but I seem to recall that, quite some time ago, MS accidentally released a WinSock (or some related DLL) build into production that still had a hard break in it from one of the testers. It was really annoying, because it was actually in the MS code and would break under certain circumstances when running in debug mode. Like I said, I don't remember what build and all, but seems like it was an NT version some years back. But, from your info, it sure looks like the same issue. Anyway, if that is the case, there is nothing you can do but just live with it or upgrade the OS. :) -- 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
Re: [twsocket] breakpoint in NTDll
Hi, Wilfried, If my guess is correct and I'm not mistaken the issue is not specific to TWSocket, but to the way how Borland and MS live together. I've stumbled upon it several years ago in an application without ICS components (WinXP + BCB5). I don't remember exactly what solution was applied that time, but what I've found just now - http://cc.codegear.com/Item.aspx?id=15804. Please check if it helps in your case.

I guess not many). The only reason for this is creating attachment (file to be encoded) while it is actually encoded, but then, using the mechanism available in ICS is a waste of disk space (already encoded original data still reside on disk). I think that all users will use simple files containing ready data that is not going to be changed during encode process. Supporting other scenarions is overkill, at least for me. If you don't agree, then what if you buffer (in TBufferedFileStream) 1024 bytes, encode first 50, then (somehow) next 100 bytes changes? You still have outdated 100 bytes in the buffer. Then what? Bug, no matter what! So why should you care about size change, if you don't care about actual file changes? I don't think that you're going to support *that* scenario. -- Piotr Dałek enigmati...@interia.pl -- Promocja w Speak Up. 3 miesiace angielskiego gratis.
