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

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

Interesting.
This is occuring in an event handler, however i thought the method which triggers the event should be on the same thread. I'll look into it as there is some SQL data access going on which may make and asynchronous call.
Thanks!

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.

Of course it will be caught...

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.

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);
}

It is indeed , i intend to use Exception ex once i can actually catch the exception!
|
|
|
|

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

hi! it's again me  I want to know something...I have a listview and I am populating the list with files from ftp folder. I want to get just the xml files, so that means...only file who are finishing with extension '.xml'.
I am doing like this:
I am making a function where it get's all the files like this:
StreamReader reader = new StreamReader(response.GetResponseStream());
string line = reader.ReadLine();
while(line !=null)
{
result.Append(line);
result.Append("\n");
line = reader.ReadLine();
}
it works fine and I am getting all the files in that folder, but I want to get just the xml files...any help with that? Thx ahead

well, I guess System.IO.Path.GetFileExtension is a good place to start, if you're unable to do the filtering at the point of asking for the group of files ( which I know you can do if you're searching the local file system )
Get the extension, call ToLower() ( so that XML, Xml, and xml all match ) and check if it's .xml. If it is, add it.

thx, that helped me a lot...and I solved it...have a nice day

You can use System.IO.Directory.GetFiles(<<directory name>>"*.xml"); to return a list of files that end with xml.
|
|
|
|
|
where exactly I can put the System.IO.Directory.GetFiles(<<directory name>>"*.xml")?
I tried something like this:
string[] xmlFiles = System.IO.Directory.GetFiles("ftp://URL", "*.xml");
but it doesn't work, can you pls show me how should I use, cause I haven't used before. Thx ahead

I don't think it will work for FTP, that's what I was alluding to in my reply. So, you need to filter them manually, in the manner I suggested.

how can I get the cputime dedicated to a specific thread?
|

|
|

You can do this on a process level, not sure about thread level.
