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.

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.

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.

Hi Bjørnar!
I've not been experiencing any problem with character replacement
(å-e,

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

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...

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.

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
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!

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...

Re: [twsocket] Freeze when using smtp after recreating its parent form
Hi Marcelo! Ok, I didn't realize that that was what it was. Thanks for the clarification! I tried it in the example application but I still get the same freeze when trying to connect after the second time the form is created... Any other ideas? To rephrase a solution to the problem: If I use the standard example applications or if I put the smtp component on the main form of my own application, everything works fine on all computers since the main form is not released until the application is closed. It is when the form containing the smtp-component is created and freed when I want to send an email that I get the freezing problem the second time it is done. So why not just put it on the main form? Well I want to have the capability to send e-mails from many applications so it is convenient to have a separate e-mail unit with an Execute-function that I can call from my applications. Execute takes care of everything from creating the form that contains the smtp component and shows the sending status to initiating the properties of the smtp component with the parameters passed to Execute. It tries to send the email and returns true if the email was sent. Once again: All suggestions are appreciated. Thank You in advance!

Re: [twsocket] Freeze when using smtp after recreating its parentform
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 You
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

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:

Hi! 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. The problem has to do with freeing the smtp-components parent form. 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. (I get the same error when setting Action to caFree in SmtpTestFrom.OnClose.) Is it not a good idea to free a manually created form?

Re: [twsocket] Freeze when using smtp after recreating its parentform
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. procedure TForm2.Button1Click(Sender: TObject); begin SmtpTestForm := TSmtpTestForm.Create(Application); SmtpTestForm.ShowModal; end; procedure TSmtpTestForm.FormClose(Sender: TObject; var Action: TCloseAction); begin Action := caFree; end; Also read my response to Arno. I'm very thankful for all the help I can get! // Henrik -Ursprungligt meddelande- Från: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] För Frans van Daalen Skickat: den 11 december 2006 10:39 Till: ICS support mailing Ämne: Re: [twsocket] Freeze when using smtp after recreating its parentform - Original Message - From: Henrik [EMAIL PROTECTED] To: twsocket@elists.org Sent: Monday, December 11, 2006 9:59 AM Subject: [twsocket] Freeze when using smtp after recreating its parent form Hi!

I normally just call .free never used .released. I also make the SmtpTestForm a procedure based variable in these kind of constructions. -- 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 -- 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 its parentform
Hi Arno and thank You for the reply! I use V2.32 of SmtpProt.pas (the one You get when clicking Download the latest ICS-V5 Distribution on overbyte.be) and Delphi7. Trying to solve this mystery I have now discovered two things: * Since You did not experience any problem I decided to test the example application on another computer by copying the exe-file. Here the second time I show the SmtpTestForm and presses the All-in-one button everything works ok and the mail is being sent as expected!!! Do You have any ideas on what can be the difference between these computers that leads to the freeze problem on just one of them? (both has Win XP SP2 and the latest Windows update patches) * I don't know if this gives any clues but a workaround on the computer where the problems appear is to either not destroy the form OR create a dummy smtpCli component like in the code below! procedure TForm2.Button1Click(Sender: TObject); var dummySmtpCli : TSmtpCli; alreadyCreated: Boolean; i: integer; begin SmtpTestForm := TSmtpTestForm.Create(Application); // Workaround that prevents freezing on some computers alreadyCreated := false; if Application.ComponentCount 0 then begin for i := 0 to Application.ComponentCount-1 do begin if Application.Components[i].Name = 'DummySmtpClient' then begin alreadyCreated := true; BREAK; end; end; end; if not(alreadyCreated) then begin dummySmtpCli := TSmtpCli.Create(Application); dummySmtpCli.Name := 'DummySmtpClient'; end; try SmtpTestForm.ShowModal; finally SmtpTestForm.Release; end; end; Any further thoughts on the matter is greatly appreciated! // Henrik -Ursprungligt meddelande- Från: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] För Arno Garrels Skickat: den 11 december 2006 10:32 Till: ICS support mailing Ämne: Re: [twsocket] Freeze when using smtp after recreating its parentform Hello Henrik, Just tested with latest V5 beta, but works great? --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html Henrik wrote: Hi!

Re: [twsocket] Freeze when using smtp after recreating its parentform
Hi again Frans! Sorry, for not expressing myself any better. No need for excuse, it was probably I who misunderstood You... 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 Yes, I think so. (The freezing occurs when trying to connect the second time the SmtpTestForm is created) and my second remark was If you replace the .release with .free is the problem still there?. Yes, it's still there (and also if using Action := caFree in OnClose) 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.
