System.Environment.MachineName will return the current machine's netbios name.
System.Environment.GetEnvironmentVariable("COMPUTERNAME") will return the computer name

I don't know how many times you intend to ask this question, but it might help you to get an answer if you FOLLOWED THE GUIDLINES in "how to get an answer to your question" above. What do you mean when you say "sql is not supporting the unicodes". Are you getting an error when you try to insert/update a field that contains a unicode character? Are you getting incorrect data when you read the data back ? Or ar you looking ad the DISPLAY, and not realizing that the font used can't display that character (for instance, in Management Studio)?
Sql server has supported Unicode for quite some time (NCHAR, NVARCHAR and NTEXT data types), but depending on the version installed, some tools may not display those correctly, substituting typically a 'box' character for those not in the current font. The data is correct, its just that the reading application cant display it using the font it is running with. Not sure what your problem is, since you have discribed it so poorly, but I suspect it is the disply issue, since that commonly trips up newbies (who also tend not to pay attention to posting guidelines).

Hi!
Is there a way to check if an event handler for an object has been already assigned in "current" object?!
ex.
<br />
class objOne{<br />
public event EventHandler<EventArgs> someEvent;<br />
}<br />
<br />
class objTwo{<br />
public objOne;<br />
<br />
public event EventHandler<EventArgs> someOtherEvent;<br />
}<br />
<br />
class objThree{<br />
objThree(objTwo someObjectTwo){<br />
someObjectTwo.someOtherEvent+=new EventHandler(someDelegate); <br />
}<br />
<br />
void someDelegate(object sender, EventArgs e){
objTwo.objOne.someEvent+=new EventHandler(someOtherDelegate); <br />
}<br />
}
someDelegate is invoked a few times and evey time it adds someOtherDelegate to the objTwo.objOne.someEvent.. my goal is to add this delegate only once..
the only idea that comes to me is to add a flag field in objOne specially for objThree but that takes away flexibility..
thanks for any help!!

Instead of simply declaring the delegate, assign null to it.
public event EventHandler someEvent=null;
check for null before adding to the delegate .

i can check for null only in the class in which i declare the event..
i "resolved" the problem by trying -= the delegate form event before i += it..
thanks anyway

cant U check like:
if(objTwo.objOne.someEvent==null)
objTwo.objOne.someEvent+=new EventHandler(someOtherDelegate);
This will allows only first assignment.
Seishin# wrote: i "resolved" the problem by trying -= the delegate form event before i += it..
Though this statement will make the delegate invoke only one function,
U R remiving and assigning the function each time.
Or can't u simply assign with "=" sign instead of +=, so that it will
overwrite any existing one.

nope.. as i wrote you can check event for null only in the class where you declare it.. in this case it would by objOne.. in objThree I can only += or -= delegates..
Arun.Immanuel wrote: Though this statement will make the delegate invoke only one function,

yup.. and thus it'll prevent adding more than one instance of my wished delegate from objThree to someEvent.. if i didn't try to -= the delegate another instance of it would be added later and in effect in stead of caling the delegate once i'd do it as many times as i added it..
Arun.Immanuel wrote: Or can't u simply assign with "=" sign instead of +=, so that it will

putting aside the fact that you cant do something like that, I'm assigning delegates to this event in other classes too so i can't do something like that..
btw. you shouldn't use the U in stead od 'you' etc. on this kind of forums (this kind of writing has its name but can't remember it  )

so , how to get his real ip
if he uses DSL Connection his ip will be as an example (10.0.0.3)
& this certainly cann't be acessed ,,,
we need the real ip

The "real IP" is the one visible to the internet. You can't get his private IP on his local network. There's, usually, no direct route for IP packets to go to get to a private IP address. His router has to be setup to allow, and redirect to his machine, the connection request from your machine on the Internet.
