Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hello Dan! Yes, Wilfried Mestdagh helped me with that. He actually read my mail and understood why my own strange workaround worked. (Thank You Wilfried!) Both Wilfried and I are professional developers though, and we do not feel very comfortable using workarounds in opposite to find the actual error. After days of investigation, (and tries to make everyone understand that it was ICS way of coexist with other good applications that was the problem), I had to look at it with financial eyes and had to let go and choose another solution. Thank You for all the help! Best Regards Henrik Ps. You can read in earlier mails why I do not want the dll to be loaded at all time. Since I regrettable no longer use ICS I'm unsubscribing to this email list for the time being. -Ursprungligt meddelande- Från: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] För Dan Skickat: den 25 januari 2007 22:44 Till: 'ICS support mailing' Ämne: Re: [twsocket] Freeze when using smtp after recreating itsparentform I thought it was figured out that dynamically unloading and reloading the dll was the problem, which other components probably don't do, and I think you were given a workaround that worked...to load it manually so that the loaded count always stays above 0 and it remains loaded.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hi Arno! As I've said before Arno, You're a funny guy, though I'm sure unintentionally. Doesn't seem so long ago You kept going on with viruses and trojans and didn't even seem to read the note I made about that we were able to duplicate ICS's problems with the environment on a _brand new_ computer... :-) Never the less I'm glad You've come to Your senses but I had to draw the line somewhere. Perhaps I can look in to this in the future but as it is now I've invested far too many days trying to find the solution to the problem. // Henrik Ps. By the way Arno, it's not that constructive to blame everyone else before sitting down and actually think the problem through. I've mentioned this to You before. I think You could learn a great deal from Wilfried Mestdagh there. In my experience he is very constructive in his way of encircle the problem. In this example: As You know there are many solutions out there in the same fields as ICS that do not have any problems with certain environments that evidently causes problem for ICS. Even though sincere I don't think it promotes ICS that You suggest that ICS-using developers every time there comes up a new environment causing problem for ICS, and after they on the customer side have had to trace down what new application or what ever that that causes problems for ICS this time, is forced to turn to the computer manufacturer or external application developer and ask them to remake their part before ICS is going to work... Especially when other competitors has products that works in the same environment. Well this was just a personal opinion. Thanks once again for the help.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Can't help myself... just have to comment this... (sorry) You can read in earlier mails why I do not want the dll to be loaded at all time. 1) You didn't want a dll linked to _your application_ even when you can be pretty sure that the DLL itself is already loaded in memory at all times whether you use it or not 2) You can be sure that outher components load the same DLL at startup time and are linked to your application during the entire execution. Note that this is the standard behaviour of all DLL-handling. If your programs are not sprinkled with LoadLibrary() calls, you now have a lot of work in front of you so you can save memory in your applications... So... Who do we blame for all the trouble? Yes.. The one whoever came with the overambiscious idea to support dynamic loading of the Winsox-DLL(?) ... :-D -- 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

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
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
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!

Well I've tried to assure You of this in earlier emails. Of course it must be some environmental condition that makes ICS hang since the same application works on some and hangs on some. (If it makes You feel better You can even call it external differences :-).) But the point is that as long as ICS makes the application hang on SOME healthy computers, its impossible to use as a part of our applications. We have too many customers world wide to take that risk. I know that it is easier not believing but it _is_ possible to duplicate this error on proven healthy computers. At our company we have been able to duplicate the freeze on not one but TWO of our test computers where one of them are NEW. Have you scanned with a different AV tool yet, i.e. Norton AV trial? Have you checked for spyware and trojan horses? Well I hope that Dell, in this case, doesn't sell infected computers but just to try make a believer out of You I now (once again I might add) tested both computers for virus with: Norman, McAfee and Trend Micro.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
I tested the NUMPROC=1 but with no difference I'm afraid... Well, perhaps we've done what we can for now. As I've said before: Thank You very much for Your efforts! I can not spend so many more days on this now (the same for You I would imagine) I have not read the whole thread but I saw that using WSocketForceLoadWinsock solve the problem. Why not using it ? It has no adverse effect in your case. It would be annoying only when your application has to run whenever winsock is installed or not. Those days, it is hard to find a system where TCP/IP stack is not installed ! Contribute to the SSL Effort.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
I use the same component and send norwegian, swedish and even chinese chars in the subject (but Outlook can't show chinese in the subject on my computer). 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)) + ?=; If you have a GUI-component that can handle WideStrings, then you can have any language in the subject using the above form. First the unicode-string is UTF8-encoded, then it is Base64-encoded and I think this form can hold any possible char. If you use Quoted printable instead you would save a little space because only the char's above 126 or so is encoded, I have code for this too if you ar interested.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hi again Wilfried and thank You for Your endurance! I'm sorry to say that using the IP address doesn't do the trick. A difference is that no log entry is made at all the second time connecting before the application hangs. Since I really appreciate Your effort Wilfried I reinstalled the TCP stack to 'prove' that the error is not at that end. And once again I'm sad to say; the reinstallation did not get the error go away on none of the both test computers where I can duplicate my customers reported application hang. Perhaps it is a good thing since these two are both brand new computers with the latest updates and so on. One thing that troubles me is that smtp-components from other vendors works fine also on the computers where ICS gets into trouble. If I for instance use the same test with Indy everything works fine! What is ICS doing that none of the other smtp components or applications are not? I'm out of ideas since a long time now, but a BIG clue to this problem must be that it doesn't happen the first time the component is created (= dll loaded). It is the subsequent times that something can go wrong. This means that You can start lots of SmtpTest-applications at the same time and connect them without getting into trouble. It is only when you're trying to connect multiple times from the same application that You get the hang on these computers.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hi again Wilfried! The other computer where the example application hangs also has an Intel Dual Core CPU and Win XP. (According to Arno he had tested the example procedure we have been talking about on a computer with Intel Dual Core and XP without any problems. I don't know if he really got the description of the example setup though since he continued to talk about external issues... :-) Indy and many others use blocking calls to winsock while ICS uses the non blocking calls. Is this also true with SyncSmtpCli? (because the same problem occurs using that) I suggest you keep on using the ForceLoadWinsock...

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hello Henrik, It could be an error in the Winsock load/unload of ICS. Or a windows bug for the dynamically load / unload. Or a winsock bug because of the dual cpu. Or some combination. The latter is easy to test. Put in boot.ini: /NUMPROC=1 or /ONECPU and reboot. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html 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

Hi Bjørnar! Thanks for Your input!

My company have made software based on ICS that run on W95, W98, NT, W2000, WXP and Vista. The components used is HttpCli, SMTPCli, HtmlSMTPCli, POP3Cli, HttpServer, SocketServer and WSocket (including the SSL-versions of the components). I have no problems on any platforms. The only time I have had problems, have been other components that needs for example Mime32.dll or other dll's that come from installing programs that is not standard in the platform. Or maybe to old winsock. Some times I have had trouble when freeing a component from inside an eventhandler for the component, or freeing a form that contains a component that is still working, but that is bad programming, even if it made problems only on some of the platforms. Regards Bjørnar am not willing to accept that it isn't possible to use ICS components on all computers.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Arno and others, More facts and thoughts that perhaps can shed some light on the error or point someone with more knowledge on ICS than me in the right direction: * You don't have to actually _send_ an email to get the error. It also happens if You just connect. To try this: - create form - press connect - close and free form (not application) - create form again - press connect and the program hangs * My workaround so far is to create another smtp component that exists all the time the application is running. I now discovered that this is also true with the Wsocket component. For instance put it on the main form and everything works on all computers. * Could it have something to do with disconnecting the connection? If we put a none used smtp component or none used wsocket component on the main form it automatically takes care of something that else get lost when the smtp component is freed on these computers? (And when the smtpform is created the second time its already there.) * I've now tried the earlier described demo program on 7 different computers. The error is shown on two of them. Both new Dell Precision with Win XP Intel Core Duo processor. * That everything works the first time indicates an internal component problem rather than external (firewalls, anti virus applications and so on) Thanks again guys!

I'm thankful for all the help I can get so if it is possible for You to investigate this I'm very grateful! I sending the files to Your private mail. If some one else want to test this please feel free to email me for the files or do the following procedure: * Open Your favorite demo of MailSnd, MimeTst or MailHtml.

Write the following in the buttons OnClick method: procedure TForm2.Button1Click(Sender: TObject); begin SmtpTestForm := TSmtpTestForm.Create(Application); try SmtpTestForm.ShowModal; finally SmtpTestForm.Release; end; end; * Click on the Delphi menu: Project-Options, and remove the SmtpTestFrom from the Auto-createForms list. * Run the application and click Button1.

Hi Wilfried and thanks for a fast reply! I'm sending You the new demo. At my end it does not make any change removing the application wide exception handler.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Well ok, strange sense of humor anyway since its pretty obvious that the virus solution is not the rescue this time. I don't blame him though. I myself speculate wildly and tend to grasp the all mighty virus solution when it is something that I can't explain or duplicate at my end when my customers have problems. Since I'm the only one of us that so far has found a computer where I can duplicate this behavior, You have to trust me when I say it not a virus causing this! Except that we've been working as a computer consultant since 1988 and experienced all kinds of viruses first hand at our customers (meaning we _know_ how to protect from, and detect, malignant software), it is too many facts already mentioned to really believe that it could be anything like that. For instance: - Why would a virus be designed to bee in the way for just ICS and not Indy - Why would a virus care if You use standard ICS demo application or if you launch the same application from a main form. - Why would a virus let You send as many emails You want the first time you start an application and use the create/free -approach and mess with You the second time. - Why would a virus stop messing with You if it detects that there are two smtp components or that the winsock dll is loaded manually :-) Well You get the grip...

Henrik, am not willing to accept that it isn't possible to use ICS components on all computers.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
I have not paid very much attention to this duscussion, but I want to say something about using ICS on many diffent computers and different platforms. My company have made software based on ICS that run on W95, W98, NT, W2000, WXP and Vista. The components used is HttpCli, SMTPCli, HtmlSMTPCli, POP3Cli, HttpServer, SocketServer and WSocket (including the SSL-versions of the components). I have no problems on any platforms. The only time I have had problems, have been other components that needs for example Mime32.dll or other dll's that come from installing programs that is not standard in the platform. Or maybe to old winsock. Some times I have had trouble when freeing a component from inside an eventhandler for the component, or freeing a form that contains a component that is still working, but that is bad programming, even if it made problems only on some of the platforms. Regards Bjørnar am not willing to accept that it isn't possible to use ICS components on all computers. I won't accept that too, but nobody from this list has confirmed the problem and nobody seems to know how to solve it.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Question: We do understeand the word 'Freeze' the right way ? Form cannot moved, closed, application cannot quit, etc... Right ? It was writen in some previous posting that the application was then at 50% cpu, so on a hyperthreaded cpu, the application is in some fast loop, i gues It's an Intel Core Duo on the machine I use to duplicate the problem.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Henrik,
I still guess that it's caused by any crap process running on
this box. Why else does it not happen on other computers as well?
I don't know the Norman software, but have you tried to uninstall it?
I would also check the auto-started processes as well and turn
them off one after the other. Then I would search for strange
processes in the process list that do not exist on the other,
working boxes. That's at least worth a try.

Hello Wilfred!
Yes, I get the same behavior when running the application from within
the
IDE. So I traced the code up until the application stops to respond.
(And
yes, we mean the same thing: the application freezes or hangs so that

can't quit and You can not move or close the window.)
The trace disappears in the function
WSocket_Synchronized_WSAAsyncSelect in
WSocket.pas. You can see the actual line where something happens in
the code
snippet below:
function WSocket_Synchronized_WSAAsyncSelect(
s: TSocket; HWindow: HWND;
wMsg: u_int; lEvent: Longint): Integer;
begin
SaveTrace('Start WSocket.pas: function
WSocket_Synchronized_WSAAsyncSelect');
if @FWSAAsyncSelect = nil then
@FWSAAsyncSelect := WSocketGetProc('WSAAsyncSelect');
SaveTrace('Hang on the line below this row: Result :=
FWSAAsyncSelect...');
Result := FWSAAsyncSelect(s, HWindow, wMsg, lEvent); // --
Something happens here
SaveTrace('Hang on the line obove this row: Result :=
FWSAAsyncSelect...');
SaveTrace('End WSocket.pas: function
WSocket_Synchronized_WSAAsyncSelect');
end;
Does this make any sense?
Best Regards
Henrik
Ps. If there by any chance is someone who want a bit more in depth
facts,
I also attached the following trace logs :-)
I added the SaveTrace procedure seen in the snippet above at the
first line
and the last line of the following functions and procedures:
WSocket.pas: function XSocketWindowProc
WSocket.pas: procedure TCustomWSocket.WndProc
WSocket.pas: procedure TCustomWSocket.WMAsyncGetHostByName
WSocket.pas: procedure TCustomWSocket.TriggerDNSLookupDone
SmtpProt.pas: procedure TCustomSmtpClient.WSocketDnsLookupDone
WSocket.pas: procedure TCustomSocksWSocket.Connect;
WSocket.pas: procedure TCustomWSocket.Connect
WSocket.pas: function WSocket_Synchronized_WSAAsyncSelect
So after the ConnectButton in the example is pressed I get the
following
results on computers where everything works:
First time the SmtpTestForm is created and ConnectButton is pressed:

Re: [twsocket] Freeze when using smtp after recreating itsparentform
I normally just call .free never used .released. You have to use Release when called from an event handler which originate from the form you are freeing. Release make sure all curent events are processed. Free does an immediate free which will crash the application if one event handler is still running. But that was not the case with this code, there was just a showmodal -- 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] Freeze when using smtp after recreating itsparentform
Hi Frans! Yes, each time You press the button the form is created and then released. You also get the same problem if You set Action to caFree in the OnClose of the created form. Sorry, for not expressing myself any better. My question was If you run the debug and while entring the buttonclick is the .release finished so did you find the form to be free-ed already and my second remark was If you replace the .release with .free is the problem still there?. My final remark was that I normally have the form as a procedure variable as it is not needed to be defined outside the buttonclick event and maybe that also solves your issue. -- 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] Freeze when using smtp after recreating itsparentform
Henrik, Hmm, your 'workaround' doesn't sound logical, why should a secondary instance of a _V5_ component have any effects, strange? Do you close the SMTP-form while mail is been sent? Is the SMTP-form yet destroyed when you create another one? When does it freeze exactely (try the buttons on the left, Connect etc. instead)? How is the CPU load when it freezes?

I have probably misunderstood something because I get the same behavior described below no matter which of the components SmtpCli, SyncSmtpCli and HtmlSmtpCli I use.

You can easily duplicate the behavior with one of the standard demo applications: * Open Your favorite demo of MailSnd, MimeTst or MailHtml. (I proceed with MailSnd-demo below.) * Add a new form with a button to the project. Write the following in the buttons OnClick method: procedure TForm2.Button1Click(Sender: TObject); begin SmtpTestForm := TSmtpTestForm.Create(Application); try SmtpTestForm.ShowModal; finally SmtpTestForm.Release; end; end; * Click on the menu: Project - Options, and remove the SmtpTestFrom from the Auto-createForms list. * Run the application and click the button. SmtpTestForm opens and You can send lots of e-mails. * Close SmtpTestForm and press the button again. Try to send yet another email and You get stuck! I guess I'm doing something fundamentally wrong?! I have narrowed it down to that everything works as expected if I don't release the form.

Re: [twsocket] Freeze when using smtp after recreating itsparentform
Hi, Procedure Variable is a variable that has scope only for a given procedure. Example: procedure MyForm.ButtonSendMailClick(Sender : TObject); var MySendMailForm : TMySendMailForm; -- Procedure Variable, for its only accessible inside this procedure (ButtonSendMailClick)... begin MySendMailForm := TMySendMailForm.Create(params..); etc... . end; Regards, Marcelo Grossi My final remark was that I normally have the form as a procedure variable as it is not needed to be defined outside the buttonclick event and maybe that also solves your issue. I don't know if I understand You correctly but I think I'm doing the same; I have a separate email unit in my code library with a single Execute function that takes the necessary e-mail settings as parameters (host, emailaddress and so on), shows a status form and returns true or false depending on if the email was sent or not. This function takes care of everything for me so I can use it to send email from any application just using the Execute function.
