 Hello, i am trying to write an application that saves about 11,520 images a minute a windows disk. The image size varies round the 8 to 20 kb. The application needs to run 24 / 7. At the moment i have a windows XP server service pack 2 and if i run the application after a 5 / 10 min the server crashes as the memory goes up and up. The commit charge rises all the time. I dont think i have a memory leak in the program but maybe the application is stressing the OS. Any raccomandations? any tuning i can do to the system. The application is written in c# .net v 2.0
Any help would be great as i have been banging my head on a wall now for some time
Thank in advance to any one that will take the time to read this

11520 a minute equates to 192 a second, sounds like alot of disk IO but maybe im wrong!
Are you sure you are disposing of objects correctly? Anything which implements IDisposable should have the Dispose() method called when you are done using it. If I remember correctly Image is IDisposable - could this be it?

Hello and thank you for your replay, I am callind Dispose() on any object that implements IDisposable!
I am really stuck, not sore what it could be

It could be that writing 192 images a second is too much for windows to handle, have you tried it on a smaller scale?

If memory keeps going up and up, the system may be too busy to allow the garbage collector to continue collecting. You can force a garbage collection using GC.Collect() and GC.WaitForPendingFinalizers().
Also, after you dispose an image, make sure you call GC.SuppressFinalize(theImage) so that the GC knows the finalizer doesn't need to be called on the image.
Since you're doing so many images per second, every little bit counts. If you're still having trouble, try running your app under a memory profiler such as ANTS[^].

Hi
Has someone any experience with such an upgrade?
I am going to do that with my C# windows based application.
Is it safe to install VS2005 with VS2003 already installed?
Is it fully compatibile?
I mean can I have installed simultanously both versions?
Any advice or warning?
Thanks
Ela

At home I've only tried opening very simple VS 2003 apps. in VS 2005. There were no problems. Might be a different with an industrial-strength app. that you might have at work. Where I work at the moment, a colleague will shortly be attempting to open one a VS 2003 web app. in VS 2005 and seeing whether everything workss.

Yes to all. You shouldn't have any problems. VS 2005 will install side by side with VS 2003. Only issue might psossibly be the database, if you're also installing SQL Server 2005 alongside SQL Server 2000. For myself, I never had SQL Server 2000, but I did have MSDE 2000 and ran into some issues. But the upshot is that I still have MSDE 2000 installed as well as SQL Server 2005.

You will certainly get quite a few warnings when you open VS 2003 projects. Some of these will be for obsolete method calls (the app. will still run, but they just suggest that you use a newer API). You'll also get warnings in HTML files because they're now tracking XHTML 1.0. But again they'll still run.
C++ code will definitely be something different though!

Hi Kevin
Thanks for the link. I am upgrading windows application not web one.
However some issue will be usefull I supppose.
I have upgraded my aplication and everything was fine except code written in C++. There was a change in C++ compilator in VS2005 and I am struggling with that now

OK, yes you'll have fewer problems with windows forms than ASP.NET.

Yes, I warned you that you might have problems with C++! 
Try googling on "Breaking changes in Visual C++" or something like that. A lot of the problems are to do with MS making the compiler more conformant with the C++ standard.

I have been founding in google etc. and I did not found anything usefull.
However I am still looking for that.
I consider to translate the C++ code to C#. I was going to do that in the future but maybe I will have to do it now.

Yes, you can safely have them installed side by side.

hi all,
TimeSpan saat = DateTime.Now.TimeOfDay;
lblLoginTime.Text = saat.ToString();
this gives me something like this > 15:03:12.1532500
i just need 15:03:12  i dont want fraction. how should i change my code ?
|
|
|
|
|
split(saat,".")
Phanindra...
|
|
|
|
|
TimeSpan saat = DateTime.Now.TimeOfDay;<br />
lblLoginTime.Text = saat.ToString();<br />
lblLoginTime.Text = lblLoginTime.Text.Substring(1, t.IndexOf(".") + 1);
|
|
|
|
|
lblLoginTime.Text = Convert.ToDateTime(DateTime.Now.TimeOfDay.ToString()).ToString("HH:mm:ss");

TimeSpan saat = DateTime.Now.TimeOfDay;<br />
lblLoginTime.Text = saat.ToString().Substring(1, t.IndexOf(".") + 1);<br />

|
|
DateTime.Now.ToShortTimeString()
|
|
|
|

hi, i don't know another way to do it. but you can try doing an substring to the string, in this way works to me jeje... hope you find it usefull 
TimeSpan saat = DateTime.Now.TimeOfDay;
lblLoginTime.Text = saat.ToString().Substring(0,8);
