not catching my exception
-
Hmmm... if the smtpClient uses another thread, this won't be caught, you need to actually set a handler for exceptions from another thread.

try
{
smtpClient.Send(mailMessage);
}
catch (Exception ex)
{
eventLogImport.WriteEntry("SMTP Email error: could not send email.", EventLogEntryType.Warning);
}Hi, The above code still throws an unhandled SMTPException when smtpClient.Send is called. SMTPException is derived from System.Exception so should it not be caught? Thanks
i see something else thats wrong-ish your compiler should be giving you a warning "ex is declared but never used"... if you don't intend on using ex don't declare it...
catch (Exception)
{
eventLogImport.WriteEntry("SMTP Email error: could not send email.", EventLogEntryType.Warning);

Of course it will be caught...

if thats the case than its all good :) ive seen programmers IGNORE compiler warnings and that just irritates the living S**T out of me... just thought id point it out incase you didnt notice :) good luck

So what exception are you getting where? Please post a stacktrace with line numbers and post the 3-4 lines aournd where it claims the exception is happening.

It must catch it (you still dont say the exact exception type I was asking for), if it does not, either your code is wrong, or something else. So how do you get that stacktrace? How did you print it out/copy it? I also note, you turned off debugging (and hence no linenumbers). It is not possible to accurately pinpoint the exact exception point in an optimized run mode. Lastly debugging a service is no more dificult to debug than any other application. 1. Start service. 2. Set a few breakpoints. 3. Attach to service process with debugger. 4. Wait for exception.

Interestingly enough, I see that the first thing this does is start off a new thread. As Christian said, this could well be the issue. Try using Application.ThreadException to catch the exception.
