yeah i did, but i couldnt get the math class in system.namespace

What do you mean you can't get it?
It is definitely there 
If you mean you can't instantiate it, yes you can't, since it is a static class.
Usage: System.Math.Sqrt(100);
Actually you can omit "System" since the System namespace is being imported automatically.

thanks for your support,
i get a system.math.dll file and i import it and its working...

That is not correct. The Math class is in the mscorlib.dll library, which you already have a reference to.
Despite everything, the person most likely to be fooling you next is yourself.

Is it?

My fault, I meant that some libs are being referenced automatically (mscorlib.dll for example).
But this is not the case here

Hi,
In one of my application created in C#, i am taking back up of data in text file. The data is fetched from db and inserted into datareader. Then each column is read and appended in StreamBuilder with "," delimiters. In this way i append about more than 1000 records in one string builder.Now this builder is written in file using Stream Writer. On checking the file i found that data of few columns of only one row contained junk characters. What should be the reason and how to solve/take care about it.
Regards

There are two dates , date1, date2 and two textboxes for time , time 1,time2
Suppose date1 contains 01/12/08 and date 2 contains05/12/08
and time 1 contains 10.00am and time 2 contains 03.00 pm
i want total hours from date1 to date2 from time 1 to time2 .

Create to new DateTime object, passing your dateX and timeX to the constructor, then subtract one from another and convert to hours

Use the TimeSpan class. Google could have helped you get that answer in a whopping 5 seconds.

I want to run my .NET application from client PC. .NET application will be placed on server. When I run the app, it gives security error (.NET security policy). How do I solve this? I've search about this on the internet, but could not find anything that solve my problem. It seems complicated. Anyone knows any simple article? Thanks.

Applications running in the Intranet have less rights than ones running on the computer you are using. The simplest fix is to run it from each machine. If you need to run it from the server you have to manually give it rights on the machine through the .Net Configuration MMC.
The way I solve this problem, and there are some reasons this won't work, but it does in most cases, use ClickOnce. It will install on each computer and check for the most updated version automatically(depending on settings), as well as you have the choice to allow it to run only online(your choice), or allow it to be installed and ran anytime.
Hope this helps, or at least sends you in the right direction.

I previously run it from each machine. I want to try different approach. It is quite hard upgrading the application. I have to visit each machine, or ask them to update it by them self.

The previous post is correct in explaining the reasons and one way to fix the problem. The other option if your program is .NET 2.0 or higher is to upgrade the client machines to .NET 3.5 SP1 (the newest). That will change the default security policy of programs running from the network to match the policy of programs running from the local machine.

Should I use my app.config file or the Resources.resx in VS2008 to store the connection string for my DB?
I am not sure which one would be better should I later on decide that I want to give the user the option to edit this.

The resx files are being compiled into your assembly, so you'll not be able to change stuff in it without recompile.
If you plan to give users possibility to change the stuff choose appconfig

Ok, Thankyou very much! I'll do that.

I agree with this recommendation. If it's a setting you want the user to be able to configure use the app.config file. resx files are for more fixed resources that only you provide.
Lev Danielyan wrote: so you'll not be able to change stuff in it without recompile
Not quite strictly true. Resources can be compiled into satellite assemblies so you can provide a new set of resources without recompiling the app. (This is mainly used for things like internationalisation & localisation. a satellite assembly will be produced for all the different languages the app is used in).

Right, but you will still need to recompile the satellite assemblies

Well it depends what Type "this" is.
In some cases Streams/IO and such, they are fairly comparable. Dispose will normally call close. If an object is disposable you should always call dispose when you are finished with it to ensure the finaliser is suppressed. Normally it's ok to just call dispose, but there is no harm in closing explicitly first just to be safe.
For some types of objects, like Forms, close has a specific meaning. Close() will close the form. Dispose will probably also call close, but in many cases you may want to close the form, but still keep the object to do some work with before you are ready to dispose of it.
