[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

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! (Do You mean that You use that approach also with ICS smtp components?) 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. I must say I really like the help I've received in this forum and I would really like to be able to switch to ICS. It is sad that we couldn't solve the dll loading error that appears on some machines... Thank You very much!

Re: [twsocket] Freeze when using smtp after recreating itsparentform
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). 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
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.

I use the same component and send norwegian, swedish and even
chinese chars in the subject (but Outlook can't show chinese

Use Quoted printable or Base64 to encode special chars.
Example for Base64 could be like this (C++):
HtmlSmtpCli1-HdrSubject = =?utf-8?B? +
Base64Encode(UTF8Encode(SubjectInputFromUserEdit-Text)) + ?=;

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!
