[twsocket] q1) Doing udp communications through firewalls... q2) relaying
Hi List, I've been using ICS for a number of years and I've found it to be quite good. I like the model and the stability. But I have to questions Q1) Has anybody on the list experience with going machine->machine over the internet directly with UDP? as in STUN (i believe) Q2) I have a custom Jabber like server which we want to adapt for mass notifications to a set of connected clients. Are there any existing like implentations perhaps open-source?

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Here some more hits on WXVAULT.DLL and Embassy software. We found that the crash during the splash screen loading in AC10 on a Dell Precision 390 was caused the presence of wxvault.dll. The solution is to remove the EMBASSY software that McAfee depends on. I don't think it will disturb your AV or firewall, but it seems to disrupt the spamkiller. Well, I solved the problem. I ran the Dependency Walker utility and | profiled the WKSDB.EXE application, and it started right up. The DW | log indicated that there were failures/conflicts/whatever with a | module called WXVAULT.DLL, which is a part of the Embassy Security | Center that came installed on my new laptop, courtesy of the good | people at Dell. The Embassy software is 139 MB of security overkill | that I can't understand, much less use; so I uninstalled it and | re-started my computer. And VOILA! The Works database program fired | right up!

Re: [twsocket] Freeze when using smtp after recreating itsparentform
I'm not sure, but I think the body of the email is automaticly encoded to
quoted printable (the plain text part), I think others in this list knows
better than me, long time ago I coded with the mail-components. If you use
html-mail, then you can encode all chars like this (C++, allthough I have
not tested this encoding on the body of the mail, only the header. Remember
that you need to set the content-type according to the encoding of the body
of the mail):
String Misc::MiscEncodeQuotedPrintable(WideString text)
{
wchar_t tmp;
for (int i = 1; i <= text.Length(); i++)
{
tmp = text[i];
if (tmp > 126||tmp==95||tmp==61||tmp==63)
{
text.Delete(i,1);
WideString qpID = "=" + AnsiString::IntToHex(tmp,2).UpperCase() ;
text.Insert(qpID, i);
i += qpID.Length() - 1;
}
}
String returnString=text;
return returnString;
}
It might be that you need to change all spaces to underscore between the
for-loop and returning the text, at least if the text is in the subject you
must do that.
If you use this form in the subject, the use the following form
String Subject = "=?iso-8859-1?Q?" +
Misc::MiscEncodeQuotedPrintable(OP_UTF8Decode(source)) + "?=";
To change the html-part of the mail, you can use this:
String Misc::WideStringToHTMLEncoding(WideString html)
{
wchar_t tmp;
for (int i = 1; i <= html.Length(); i++)
{
tmp = html[i];
if (tmp > 126)
{
html.Delete(i,1);
WideString htmlID = "&#" + String(tmp) + ";";
html.Insert(htmlID, i);
i += htmlID.Length() - 1;
}
}
String ret = html;
return ret;
}
This form can hold any possible char in html.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
> ProcessExplorer: > I only find two dll's that I'm not certain what they do: > - detoured.dll > - wxvault.dll (Embassy Trust Suite by Wave Systems. Apparently > installed > by default by Dell) Google for both DDL-names, you will get plenty of hits. detoured.dll, I bet that this is the culprit: http://research.microsoft.com/sn/detours/ Detours is a library for intercepting arbitrary Win32 binary functions on x86 machines. Interception code is applied dynamically at runtime. Detours replaces the first few instructions of the target function with an unconditional jump to the user-provided detour function. Instructions from the target function are preserved in a trampoline function. The trampoline function consists of the instructions removed from the target function and an unconditional branch to the remainder of the target function. The detour function can either replace the target function or extend its semantics by invoking the target function as a subroutine through the trampoline. Detours are inserted at execution time. The code of the target function is modified in memory, not on disk, thus facilitating interception of binary functions at a very fine granularity. For example, the procedures in a DLL can be detoured in one execution of an application, while the original procedures are not detoured in another execution .. For instance Messenger Plus! uses detoured.dll If so, remove Messenger Plus! and try again. Messenger Plus! is an add-on for MSN Messenger. Messenger Plus! installs an OPTIONAL adware called C2Media which is also known as LOP.com. %PROGRAM_FILES%\messenger plus! live\detoured.dll Search your HDD for detoured.dll if Messenger Plus! is not installed, try to find the application that use it!!. BTW: Interesting sample: http://www.codeproject.com/internet/DnsHijack.asp Also upload your wxvault.dll for a online check to http://www.virustotal.com/flash/index_en.html and http://www.avira.com/en/support/verdachtige_dateien_und_sonstige_uploads.html --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html Henrik wrote: > Hi Arno! > > ProcessExplorer: > I only find two dll's that I'm not certain what they do: > - detoured.dll > - wxvault.dll (Embassy Trust Suite by Wave Systems.

WSocketForceLoadWinsock immediately load the DLL. If you down't want that, call WSocketForceLoadWinsock the first time you send a mail. Note that loading winsock has almost no impact on a system with TCP/IP network since the DLL is already loaded into the system. Loading it for another application (yours) only map it into the application virtual memory space without really loading anything. Only the data segment is private to each application and this doesn't load anything from disk. Contribute to the SSL Effort.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hi Bjørnar! I've not been experiencing any problem with character replacement (å->e, ä->d and ö->v) with ICS components, only Indy 9 and only when passing through ms exchange it seems, but I tried Your suggestion and it works like a charm with Indy 9!

Quoted printable sounds interesting as well because one of our customers report character replacing problems also with the body when sending (Indy) automated emails to a customer of theirs in Norway... Apparently all Swedish characters å, ä and ö are substituted with ?. Perhaps it is possible to use Quoted printable on the whole body? If You want you can send me the code to my private address.

To summarize the problem: When trying to switch from Indy to ICS using a company standard "e-mail unit" with a single function: SendEmail(host, address...) that takes care of creating a status form with the smtp component, our applications were starting to freeze on some machines at our customers when emails where to be sent the second time. We have now discovered that: Yes, the error do not arise when using WSocketForceLoadWinsock or having the smtp component on the main form (or creating a dummy smtp component at runtime and let it exist while the application is running). So we've found a workaround but feels a bit unsatisfied not finding what causes the problem. As I've mentioned before I'm not very initiated in the fields that ICS is handling for me and now I feel like a real rookie because I'm not that initiated in dll-using either... You say that it has no adverse effect using WSocketForceLoadWinsock in my case: but doesn't the use of WSocketForceLoadWinsock on applications startup mean that the dll is loaded the whole time the applications is running? I don't know if that has some bad effects like bigger memory usage or so but at least it doesn't feel that satisfying to have the dll loaded all the time even if the application is not going to use it. Also if I have to manually load the dll on application startup the whole idea to use one simple function to send emails get lost. That was why I used the some what strange (I admit that) work around to create an application wide dummy smtp component the first time the function is called. The dummy makes it possible to call the email function as many times You want when the application is running and hopefully it is deleted when application is closed?!

[twsocket] Need help with THttpCli
Hello,
We want to reuse THttpCli after a request ends (either aborted or
normal) in a MR HTTP reverse proxy. We also want to reuse non-aborted
sockets so as to keep the socket open in another repository thread.
Here is my logic:
I first override,
void __fastcall httpClient::StateChange(THttpState NewState)
{
if(!httpServerClient || httpServerClient->skipHTTPClientEvents)
int tester = 10;
else
THttpCli::StateChange(NewState);
}
//---
void __fastcall httpClient::SetReady()
{
if(!httpServerClient || httpServerClient->beganDetach ||
httpServerClient->responseEnded)
StateChange(httpReady);
else
THttpCli::SetReady();
}
//---
void __fastcall httpClient::TriggerRequestDone()
{
if(!httpServerClient || httpServerClient->beganDetach ||
httpServerClient->responseEnded)
{
if(FOnRequestDone)
THttpCli::FOnRequestDone(this, FRequestType,
FRequestDoneError);
}
else
THttpCli::TriggerRequestDone();
}
//---
so that no more messages post after ThreadDetach();.
Then I check for whether THttpCli is aborted. If it is aborted, I
check if it is still connected (HTTPClient->Connected). If so, I
simply delay ThreadDetach until OnSessionClosed. If not I simply
abort(); and then ThreadDetach().
Now the problem is THttpCli is so much unstable in closing, it acts
very unpredictably! When I reattach in another client, I mostly see it
is not really threaddetach'ed! (That is after threaddetach, GetHandle
is called somewhere) or sometimes the delayed threaddetach does not
work.
Francois, we would be happy to pay you the 70Euros/hr for 2 hours if
you could write a stable reuse routine for THttpCli (and we will be
donating the code).
Best Regards,
SZ
