Re: [twsocket] SMTPOpen failing, Why?
May I summarize. I have three options: 1. Continue to use "high level commands" (Open) and abort and tell the user, if the server does not support authentication. 2. Offer an option to use no authentication. 3. Chang to more basic functions and switch to no authentication in case of none available. Oh, by the way: I use V5 in this project. Thanks to all of you!

Depending on if the user supplies a password or not I set it to one of these values. It was on smtpAuthAutoSelect, which seems to trigger the "->AUTH CRAM-MD5" request. So is this a bug of TSmtpCli? Should it send an AUTH request, if the command is not on the list? What is the default in this case?

Thanks, I will consider changing to one connection in a later version. For now I have to live with user configuration. Thanks also to Arno and Francois.

Re: [twsocket] bug in smtpprot.pas
Hi Arnaldo
If you look at the source of FormatDateTime M is replaced by N if the
preceding formatting character is H. I'm not quite sure if this works
correctly, it won't hurt to change it to "nn" anyway.
All:
I checked FormatDateTime routines and they are all the same (regarding
speed).
So a call like
Result := DateToStr (t, RFC822_FormatSettings) + ' '
+ Time(t,RFC822_FormatSettings) + ' '
+ TimeZoneBias
with the following constant
RFC822_FormatSettings : TFormatSettings = (
CurrencyFormat:3;
NegCurrFormat: 8;
ThousandSeparator: ',';
DecimalSeparator: '.';
CurrencyDecimals: 2;
DateSeparator: '.';
TimeSeparator: ':';
ListSeparator: ';';
CurrencyString:'€';
ShortDateFormat: 'dd.MM.';
LongDateFormat:'ddd, d mmm hh:nn:ss';
TimeAMString: '';
TimePMString: '';
ShortTimeFormat: 'hh:nn:ss';
LongTimeFormat:'hh:nn:ss';
ShortMonthNames: ('Jan', 'Feb', 'Mar', 'Apr', 'May',
'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec');
LongMonthNames:('January', 'February', 'March',
'April', 'May', 'June', 'July', 'Augut', 'September', 'October',
'November', 'December');
ShortDayNames: ('Sun', 'Mon', 'Tue', 'Wed', 'Thu',
'Fri', 'Sat');
LongDayNames: ('Sunday', 'Monday', 'Tuesday',
'Wednesday', 'Thursday', 'Friday', 'Saturday');
TwoDigitYearCenturyWindow: 0;);
would be easier to read.
Moreover according to Delphi Help it would be thread save in opposition
to a call without a TFormatSettings parameter.

Re: [twsocket] Memory Leak in SmtpProt
Arno,
That might be true. By the way: Wouldn't the following be sufficient?
It should be much faster:
if FMailMessage.Count > 0 then
When will the next beta come out? Is there a time line? I know
Francois is busy. Is he controlling releases alone or are others
(like you) helping him on this? Because there is this other issue
of which I'm not sure how important it is (see article: bug in
smtpprot.pas by Marcello Vezzelli and its follow-ups) with at
least two issues concerning RFC822DateTime.

[twsocket] Memory Leak in SmtpProt
Hi
It seems that there is a memory leak in SmtpProt:
When sending an email and using MailMessage for including the
text of the mail, the text is compared with an empty string with
the GetText method of TStrings. This method creates a copy of
the MailMessage TStrings which is not freed again:
{if Length(FMailMessage.Text) > 0 then} { FP 05/03/06 }
if FMailMessage.GetText^ <> #0 then
FMailMsgTextPos := 1
else
FMailMsgTextPos := 0;
As you can Francois has already included a Fix. Why is this fix
only a comment?

I know this comes a little bit late, but...
In the same function it is tested for English/US format by only
comparing the first day (Sunday). Does anyone know if there is
any other language where the Sunday is also abbreviated as "sun"
but other days or months differ?
if ShortDayNames[1] = MyShortDayNames[1] then
Result := FormatDateTime('ddd, d mmm hh":"mm":"ss', t) +
' ' + TimeZoneBias
Francois, why do you test at all and don't use TFormatSettings
for all those functions? Is it performance? I don't know if the
overloaded FormatDateTime function with TFormatStettings is slower.
At least it makes the code much more readable and shorter (despite
the definition of the TFormatSettings as a constant).

I already did so before, but I wanted to be sure to do the right thing here.

Re: [twsocket] TnScript: Getting Received data
Thanks Francois. I think I'll do it with TnCnx although there seems to be a small problem (see other thread). Veit Francois Piette wrote: > The problem is the packet nature of received data.

[twsocket] TnCnx: Receiving NUL at end of line
Hi I'm now testing TnCnx for my purposes. It works fairly well so far. The only issue I have so far is that I#m receiving NUL characters at the end of line. For example: ' Simplified orbitography parameters :'#$D#0#$D#$A' ND 021:23'... Is this an server issue or could it be related to ICS? If I use the Demo for TnCnx it stops receiving at the end of this line while the EmulVT Demo works properly. The problem in the TnCnx (like it was in my software) is that Len is is longer than this line and output ends at the NUL. Hyperterm works well here, but I can't see if it receives the NUL character. There is a test account at netdis.cls.fr. username: EVERYONE password: ARGOS Please use it only for this verification (if you have the time to). TIA Veit P.S. I hope I can get hold on a nice card from Berlin Adlershof soon. -- 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
[twsocket] TnScript: Getting Received data
Hi There I trying to use TnScript. So far it works very well. Now I'm trying to receive some data after detecting an event string. Is this possible? Or do I have to go back to TEmulVT and do it all from scratch?
