Since it seems you are already using .NET 4, you can give a look to the new Thread-safe collections.

The simplest answer is to look at the System.Random class.

Wrap one in a class and provide the method you need.

you are to kind: you also could tell him to use the feature "object browser" with the "random" keyword Smile | :)

I cannot remember: What did I before google?

He may have tried that with "rundom". Roll eyes | :rolleyes:

I expect he'll be back asking why it keeps giving the same value over and over.

you're an optimist. I think there is no running code yet.

All can be worked out with a little bit of Google-fu. Type one thing in, 2 clicks and I got this[^]. Weak in the way of the Google are you.

Don't you think you should have stated that in your original question then? We don't read minds.

Try this:
Simple Random Number Generation[^]
And, as Peter said, why did you not say this in the original post since it would avoid people telling you to look it up in help.

Well why didn't you f*ckin say that in your original message? How are we supposed to read your simple little mind when it generates almost no electrical energy on its own?

You'll need a source of randomness and a way to map the output of that source to numbers between your two inputs.
If you want the result to be uniformly chosen from the specified interval, you shouldn't use modulo - that would result in a "first part" where the numbers have a slightly higher chance of being picked then the ones in the "second part".

edit: Ok I just saw your post that you don't want to use the random class, then look up Mersenne Twister and implement that if you want it to be useful, or any simple PRNG if you want something as bad as System.Random or worse.

A couple of points. First of all, you point him to System.Random, and then you send him over to the Java documentation - this is an inconsistent approach. Secondly, he's stated elsewhere in the thread that he wants to roll his own random implementation (it's probably homework). Finally, resources like MSDN are not always the best solution - they tend to be written by tech writers rather than battle hardened developers working with the technologies out in the trenches.

I apologize. My bad.... And I agree to the MSDN is not always the best but for beginners, it does provide a good start.... After understanding the codes on MSDN they can always try and improvise...

Can you just check if the Audio property is null?
