.NET Forum / .NET Framework / New Users / June 2007Background Timer Execution?
I am looking for sample code of a C# 2.0 Service that every 1 minute executes a method (that returns void). The timer and timer-fired method need to be fully async and background so the main service does not appear unresponsive. Can anyone show code like that? Small and simple is best. Thanks. > I am looking for sample code of a C# 2.0 Service that every 1 minute > executes a method (that returns void). The timer and timer-fired > method need to be fully async and background See the System.Threading.Timer class. [Snip all context] Alright, now listen here! That's like 10 times now I've gone to reply to a post, only to see you've beaten me to it! I'm beginning to feel like a thread stalker. First it was the Skeet character, then that Willy Coyote guy, and now you! I'm afraid you're just going to have to stop that, as I need to have the first crack at all questions. From here forward, I'll be sure to post a "Go Ahead [Peter|Jon|Willy|William]" message in each thread once I'm done with it, indicating you can now post.... (If, somehow, my humor didn't come across, either my writing is much worse than I think it is, or whoever is reading this is very humor impared....)

I guess I'll have to sneak back in and take the hidden camera out of your office. You know, the one I use to watch when you are composing a reply to a post, so that I can jump in and beat you to it. Yes, that one. :) If it makes you feel better, I still think your article on the use of .NET Sockets is one of the best things I've come across in this newsgroup, and alongside all the prepared answer articles Jon's got, as well as any number of other well-informed replies from the usual suspects, that's saying something. Besides, I just take the easy ones. :) Pete > Oops...the jig is up. You've found me out! > > I guess I'll have to sneak back in and take the hidden camera out of your > office.

Yes, that one. :) Ironically, we deal with companies doing coordination of security cameras (like wilife.com) via XMPP. As a result there are few "disconnected' video cameras scattered around the office. I think I'll check on those... > If it makes you feel better, I still think your article on the use of .NET > Sockets is one of the best things I've come across in this newsgroup, and > alongside all the prepared answer articles Jon's got, as well as any > number of other well-informed replies from the usual suspects, that's > saying something. Aw man, flattery will get you everywhere. What's amazing to me, is often I'll be looking for something crazy specialized and specific on the web ("How do I ...?") and the frequency with which I get Jon's or Willy's answers (and, to my surprise, my own!) is just scary. > Besides, I just take the easy ones. :) That's what I'm trying to do! I leave the hard ones for the smart people.

Marc Gravell keeps replying to posts and referencing classes in my MiscUtil library which I didn't even remember I'd written. How's that for humiliating?

How's that for humiliating? I've always enjoyed finding a piece of code that does exactly what I want, looking at it, and going, "Wow. Whoever wrote this knew their stuff - one day, hopefully, I'll be that good!". Then, as I keep reading, I find I'm the author. I try hard not to interpret it as, "Your best days are behind you, and dementia has set it.". It's happened to me a number of times now when I'm looking for some very specific Unicode Stuff (StringPrep related), or Async Socket / Thread code snippets. It's really amazing how, as soon as you get "uninvolved" with some of these very, very specialized topics, the detailed knowledge just disappears. For example, at one time I understood that UTF-32 encoding class you put together for me (about 4 years ago, now). If I look at it now, it's all gobbledegook. Another example - at one time I understood how COM Interop, Win32 Interop, Marshalling, COM Callable Wrappers, COM+ and Thread Apartment states worked. Now? Pfffft.

I remember the day itself though very clearly. It was a beautiful day, and we were sitting outside in the garden, with guests. But the coding was too fun :) I hope you didn't use the class though - as it was, there were bugs in it which would have come out very quickly. Now that I've started adding unit tests for my MiscUtil class, I hope the quality is improving, but I apologise for any errors that cruddy code caused... On your more general point though, I quite agree. There's just too much you need to be good at to really keep being good at everything the whole time (at least if you're a normal, sane human being rather than Don Box).

You may refer to the articles below for more details of 3 timer classes in .Net Framework and their usages: "Comparing the Timer Classes in the .NET Framework Class Library" http://msdn.microsoft.com/msdnmag/issues/04/02/TimersinNET/ If you still have anything unclear, please feel free to feedback, thanks.
