Re: [twsocket] Need a simple SMTP example
Arno, if I'd do it the way you suggest (do it async, fetching the next record in OnRequestDone and start over sending), may I use screen output from there, including .ProcessMessages? I know that a good application should display information based on a timer or such, i.e. re-displaying all info each n msecs, but for the first version, I'm very short on time ... Afaik, it should be avoided to call the message pump from /*any*/ ICS event, or is this only true for OnDataAvailable? Another question is, am I allowed to use .Abort from inside OnRequestDone when an error occurs? It seems to work, but I'm quite unsure if this is the correct way to abort a failing SMTP transmission.

No no, why would you need that? I know that a good application should display information based on a timer or such, i.e. re-displaying all info each n msecs, but for the first version, I'm very short on time ... What do you want to display? Sure, a full log displayed in a GUI control, including all data being sent will slow down entire application since displaying data in Windows is very very slow. Afaik, it should be avoided to call the message pump from /*any*/ ICS event, That's not ICS-specific, don't call the message pump from any (message- based) event handler. or is this only true for OnDataAvailable? See above. Another question is, am I allowed to use .Abort from inside OnRequestDone when an error occurs? Yes. It seems to work, but I'm quite unsure if this is the correct way to abort a failing SMTP transmission. What do you mean by failing SMTP transmission? Most error responses from a mail server should/can be handled diffently. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html Michael Arno Garrels schrieb: [EMAIL PROTECTED] wrote: Hi Michael, Sorry, I sent my previous reply directly to you instead of to the list. thanks for the hint, I already looked into the code and - by the way - I find it very well structured.

In SMTP, you encode the file using MIME Base64 encoding if its binary, and quoted-printable if its plaintext. Actually, you can use Base64 for both without any problems. dZ. -- DZ-Jay [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html -- 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] Need a simple SMTP example
Dear community, a critical situation forces me to implement a quick way for sending mailings with ICS components (all other stuff out there won't work properly, they told me). In fact, it is a rather simple scenario - walking through a customer database and sending SMTP mails to some customers, plain text and no HTML, but with one or two attachments (PDF files). It should be accomplished using Delphi 7, and we've currently installed ICS / SmtpProt v2.38. We'd like to upgrade to the most recent version next week, but work needs to be done right now :-( Can someone point me into the right direction for completing the required tasks by showing an example or directing me to some sample files?
