Use a Regex. The following should work: @"(\d{1,3}\.){3}\d{1,3}"

I thought of that, but it's not perfect. It will accept 300.534.999.21

A regular expression will do that. I suspect Expresso ( www.expresso.com[^] ) will have one to do that built in.

greetings,
one simple question:
there are 5 threads;
each one has read/write access to global object;
before read/write to object, operation is enclosed with lock keyword.
is app completely thread safe?
p.s. even if each processor enters lock (obj) statement at the same time

Hard to tell without seeing code you used.
|

i think that sample code is irrelevant, im just concerned if its theoretically possible
that two threads enter lock (obj) at the same time;
even if it isnt with single cpu, what about multi proc machine

If used properly, lock ensures one thread access the block. It won't make any difference in a multi processor machine, I guess.

explain structure with array in c#.net?
|
|
|
|

What do you need explained ? You can just create an array, but I'd use a list. You can create an array or a list of structs, same as you would any type.

You need to set up your website for this, on the server. You don't do it with code.

It depends on the website provider. Consult with them, they might provide some API's which can be used for this.

why would you want to do that?
panels go on forms, i dont think that forms can go in panels. if you want forms within forms you can google MDI windows

Hi,
have a look at Form.TopLevel
|
|
|
|
|
|
you can add parameters in the forms constructor or/and add a 2nd constructor with the parameters

Your Form should always have default constructor (with no params), else the VS designer will break.

Hi,
I've build an application but it isn't suppose to startup more than once.
How do I prevent my application to startup more than once??

Possibly the easiest way is to use a mutex. I posted a WPF version here[^], but it's easy enough to apply this to a Forms app.
