Well there are probably libraries around that you can buy that will do this. There possibly code around for free, have you even tried searching? When you post here you should have atleast had a look around for something.
Assuming that you had searched I was fairly sure there wasn't going to be any free libraries which leaves you with the option of making your own ... which is why I gave the reply I did.

You can change your question after posting it, if you think you didn't make yourself clear the first time... No need to create a new question everytime.
Here's an article about a Diff engine you could use:

You will need a Timer control for this. There are lots of examples on Google.

I have an application in C# which should be installed on 10 machines.. I would like a way to make sure that they do not install on more than that. I would like to give them a way to activate each terminal. Since all terminals will be sharing a DataBase ,maybe we can have a verification process that asks them to input an activation code.Can any one help me regarding this?

If you don't mind spending the money you can use www.copyminder.com but if I were you I would request the names of the 10 computers and their IP Addresses that the application will be running on this way you can check if a computer is one of these 10 and if so allow the application to run otherwise not.
I know it's messy and probably not the best idea, but it will work.
Freedom is the right to say that 2+2=5 if this is so everything else will follow.

Hi,
Which one gives better performance, checking a string against null & empty.
string s = "something";
for(int i=0; i<100; i++) {
if(s != null) {
if(s.Length > 0) {
}
}
}
or
for(int i=0; i<100; i++) {
if(!String.IsNullOrEmpty(s)) {
}
}
plz help,
nas

put it in a loop that will run a few hundred thousand times and use the System.Diagnostics.StopWatch[^].
It's a good idea to get used to testing things like this yourself ... it's quicker than asking on here, more reliable and you have more chance of getting an answer with some of the more obscure stuff (not that IsNullOrEmpty is obsucre).

But he doesn't want to do any of the work himself. He needs someone to do his homework form him.

Or use Reflector to check what String.isNullOrEmpty does:
public static bool IsNullOrEmpty(string value)
{
if (value != null)
{
return (value.Length == 0);
}
return true;
}
IsNullOrEmpty is therefore just a bit slower because there is a strack frame more present (for calling the method). But compared to the time you are using in writing that every time, I'd use IsNullOrEmpty

Seriously, for the additional fractions of a microsecond that IsNullOrEmpty takes I wouldn't worry about it.

Won't .Length check for null again anyway? If so, you're checking for null twice.
I'd just use IsNullOrEmpty figuring Microsoft wouldn't steer me wrong.

.Length cannot operate on null so it will throw an exception.

Well the meaning of it shows when it should be used ... it stops anyone inheriting your class, so it should be used when you don't want someone to inherit your class :P
Two examples of this in the Base Class Libraries are the List and String Builder. These 2 are sealed as they are "high performance" classes which microsoft don't want anyone inheriting and then messing around with the internals and messing them up (well thats the official line anyway).

I KNOW IT SHOULD BE USED TO DEPRIVE OF SOME INHERITING MY CLASSES.
BUT ONE CAN ACCESS THE MEMBER FUNCTIONS AND MEMBER VARIABLES BY INSTANTIATING THE CLASS.

Sure, you can access the members of a sealed class. sealed is not an access modifier like private, protected, public, internal, protected internal.
