For most purposes, the advice that (always reliable) Pete O'Hanlon gave you, to use an instance of System.Diagnostics.Stopwatch: is what you need.
But, given your requirements, you may also want to examine this April 13, CodeProject article: "Microsecond and Millisecond C# Timer," by Ken Loveday: [^].
And, possibly other resources on high-precision .NET timing at: [^].
However, I do not know if any of the techniques above can meet your requirements: I have never needed higher-precision timing than that provided by 'Stopwatch.
When you use the 'Stopwatch class, I hope you don't make the same stupid mistake I made recently [^], and use Stopwatch.Elapsed.Milliseconds, thinking that gets the total time, instead of Stopwatch.TotalElapsedMilliseconds, as was kindly pointed out to me by Alan N. here on this forum: [^].
good luck, Bill

I have successfully used (via P/Invoke wrappers I wrote) both the MultimediaTimer [now depreciated but has been available on every system I have ever tested] and TimerQueueTimer with greater precision than you are requiring.
I can dig the code out if you would like it, but it didn't take me too long to knock it up from scratch as I remember.
They are not recommended for general purpose timers however and it is very rare that level of precision is required!

If you 'need' to do this rather than 'want' to do it then I suspect you might be forced to write a OS driver. Doing that should give you complete control to collect the data at the interval you want.
The driver would do nothing but the following
- Collect the data at the required interval
- Put the data in a buffer
- Provide a method callable from an external app that returns the current buffer.
Then your application can ask the driver for the data and do whatever you want with it.
If you just 'want' to do it then some of the other suggestions will probably require sufficient functionality to get the data most of the time.

Hi all
Please clear my doubt.
I have one server system where i installed sql server.
5 client machines accessing that.
now suppose if there is any power fluctuation like it's coming for 5 min and again going and so on.
So for this kind of situation, how to save the data or how to update the database each second.??
Is it possible that at a time we update the client database also and server database also.?
i.e at button click it should update both client and server database..
Please help..

Sound like mirroring to me and yes that's a database function and not on the client. Mirroring is generally a rather complex setup between major servers I don't think it applies to mirroring to a client machine.

It is possible, you need to look up database mirroring / database replication.
Please ask further question on this topic in one of the specialised SQL forums (it can get quite complicated depending on your needs), this forum is devoted to c#. Note that if you do it properly it will be transparent to the database users.

Ok...thanks..

Same problem I faced earlier when user need to sync data with more than two databases. we keep insert, update delete operation with data in a queue and create window service that sync queued operations with other databases(may or may not be same).
It will sync deferential data not all.

Hi. Is there a way to convert html to chm file programmatically using C# WinForms? 
|

Hi guys. I need suggestions on C# projects that are not too hard but not too simple since it might be not pleasant for our professor. My group mates and I need to do an object oriented program/system and we cannot think of anything as of now since we are not really good at programming. Anyway, your suggestions are appreciated. Thanks!

Is this for a computer science course of some description? If I were looking to do something like this, I'd pick something that interests me and look at writing a project based on that. The reason for this is simple - if it's something I'm interested in, then I already have some knowledge about the topic. That makes it easier for me to design the application.

Not exactly, it's an information technology course. I really cannot think of anything as of now and we need to pass a proposal on Wednesday. I was thinking of a payroll system but it's too hard for us without any guide or help at all

Remember that you are the team who have to write the code - we aren't going to do it for you, so anything you write has to be something you know and understand. What are your interests? Are you mad about morris dancing? Do you jitter with joy at crochet work? What do you do for fun?

I know  I was thinking of tracking system/program like what delivery companies have or an information system that lists employees and tracks their attendance. Are they applicable to be object oriented? That's my problem as of now since the project we need to pass has to be object-oriented coded.

Address book, Password keeper, Home inventory, Money tracker ...

So I was thinking of creating an information system.
Modules would be:
-Employee List
-Attendance Tracking (how many absents or leaves)
-Time in and out
-Employee Information
- ???
I really cannot think properly as of now, forgive me. Is it good or bad?

Sounds like a good idea to me, but it all depends on what your professor is expecting.

This is your first projects. So you don't need to include many modules. What ever you listed is more than enough. You need to concentrate more on the functionality, the way project is structured. Try and use latest technologies. For example - Choose appropriate framework(like MVC, if it is web based), Use ORM like Entity framework.

Ooh, that's a great idea. A database that links drill bits to screw sizes and wall plugs, taking into account whether or not you need to use masonry bits.
