 Posted: Thu Feb 16, 2006 12:03 pm Post subject: TIdSMTP Exception Handling |
 |
|
I am writing a program to send emails to a mailing list in an Access table
using the TIdSMTP component. If an address is at an unknown domain then
naturally an exception is raised :-
"Project mailtommm.exe raised exception class EIdProtocolReply Error with
message . . . . . .'
I am attempting to handle this exception with the following code:-
try
SMTP.Send(Message);
except on E:EIdProtocolReplyError do
begin
Error.Text:=E.Message;
Error.Update;
end;
it does not work. I have tried E:EIdException and E:Exception with no
success. What am I doing wrong or omitting?
In case anyone should jump to the conclusion that I am spamming, the list is
to members of the Winchester & Portsmouth Diocesan Guild of Church Bell
Ringers. From time to time email addresses become extinct and the owner
fails to tell me!

EIdProtocolReplyError means that the SMTP server sent an error message back
to TIdSMTP in reply to a command that TIdSMTP sent to the server.

You are only handling EIdProtocolReplyError and no other exceptions at all:
try
SMTP.Send(Message);
except
on E: Exception do
begin
Error.Text := E.Message;
Error.Update;
end;
end;
Just saying it doesn't work says nothing about the actual problem you are
having. Always provide specific details. What exactly is happening?

EIdProtocolReplyError means that the SMTP server sent an error message
back
to TIdSMTP in reply to a command that TIdSMTP sent to the server.
I am attempting to handle this exception with the following code:-
You are only handling EIdProtocolReplyError and no other exceptions at
all:
try
SMTP.Send(Message);
except
on E: Exception do
begin
Error.Text := E.Message;
Error.Update;
end;
end;

I think I said in my original post that I have tried both E:EIdException and |
E:Exception. The result is the same. I am sorry if the meaning of 'does not
work' was not clear. The same message box appears :-
"Project mailtommm.exe raised exception class EIdProtocolReply Error with
message . . . . . . Process stopped. Use Step or Run to Continue."
However, I have just tried running the executable outside the IDE and all
seems to be as I expected i.e. no message box. Please forgive my
inexperience.

You did not say what is ACTUALLY happening.
| Quote: | The same message box appears :-

message . . . . . . Process stopped. Use Step or Run to Continue."
|
You are running your code inside the IDE debugger. What you see is
perfectly normal behavior. The debugger catches all exceptions before the
code does. Do what the message box tells you to do - use the "Run" command
(press F9, or use the menu item), and the exception will be passed back to
the code for normal handling. If your code never sees the exception, then
TIdSMTP is swallowing it internally.

|

Hi, folks!!!
I'm a forum reader and I would like make a quiz for obtain your opinion
about an interesting subject.
Quiz:
What you consider secure to use into execute method of thread, and what
you prefer to use only in syncronize method?
My opinion:
I use only string handling routines in execute method, I avoid use
objects into execute method without syncronize. Sometimes I create
TClientDataSet's in execute method, nothing more.
Thanks for all replys.

It that not a bit off-topic for this thread?
I prefer not to use a synchronized method for anything at all.

What's the problem with other stuff? OK, the VCL is not thread-safe. Apart
from that, what else do you have a problem with? The fileSystem is
thread-safe, the memory-manager is thread-safe, the Windows API is obviously
thread-safe, (apart from some very specialised debugging subSystems).

?? Instantiating, calling methods, setting properties etc. are all fine for
those objects that are not VCL components or are not thread-safe for some
other reason. I have many apps that regularly exchange objects between
threads for communication purposes.

I think you are worrying too much <g>

This topic does not belong in this newsgroup, let alone in this discussion
thread. You should have directed your posting to the .non-technical
newsgroup instead.
