yes, see martin's reply. Thats exactly why the Closing event exists, so you can prevent
a Closed event from happening.

HELLO!!!

Thanks.

This will remove the first selected item from the list view.
if (myListView.SelectedItems.Count > 0)
myListView.Items.Remove (myListView.SelectedItems[0]); /ravi

I think a javascript will help if you want it without reloading!

Ok here is the problem. I am developing a server in C and a client in C#. The server send streams of data to the client, and the client is responsible for decoding and interpreting these stream. So, if I send a simple "Hello world" from the server to the client, it works. If I send a byte representing an integer (I use memcpy) I can decode it in the client. But, the problems start when after some integers, I also put a string. If I put 2 bytes, each representing some number, I am still able to decode the string that follows using:
System.Text.Encoding.ASCII.GetString(buffer,2,length)
But if I say 3 bytes, and then the string, I don't get anything (yes, I said buffer,3,length to reflect the server changes), I get garbage.. Can anyone please help me? Thank you.

What kind of "garbage" do you get?
I think that we have to see some code in order to tell what's wrong with the code...

Okay then.
Here is the server
memcpy(msg,&type,1);
memcpy(msg+1,&nr,1);
memcpy(msg+2,&online,1);
memcpy(msg+3,&p,sizeof(p));
type is 2, nr is 4 online is 0 and p is "Hello world". And on the client I get some unrecognizable characters (those squares you sometimes get). BUT, when online is 1 the string stays in one piece.. What am I supposed to make of this?
|

|
|

if only you had shown the client code and the server code in one message...
and, if at all possible, the hex representation of these data bytes arriving at the client.
|
|
|
|
|
But I already showed more than enough. Since I am able to transmit messages between the server and the client THERE IS NO PROBLEM HERE. Anyway, the server uses fprintf and the client uses BeginReceive - EndReceive (IAsync bla bla).
The problem is the way I am handling the array of bytes coming from the server. I suspect EndReceive thinks that a 0 means \0 (as in end of string). So it stops there. I don't know why this happens..

Sorry for trying to help you. 
Debug Rule #1: when the system does not perform as designed, at least one element is wrong,
and it could be anything; not a single assumption is beyond scrutiny.

I haven't seen a single line of the code that recieves the message.

Just because some code works in some cases doesn't automatically mean that it works in all cases.

I don't know why it happens either, as I don't know if you use BeginRecieve and EndRecieve correctly.

The thing is that it's a lot of code.. Anyways, let's see... 
The BeginReceive
sock.BeginReceive(buffer,0,buffer.Length,SocketFlags.None,receive,_sock);
The EndReceive
int stop=_sock.EndReceive(result);
Is it not correct? 
|
|
|
|
|
That code is correct, but I have no idea if the surrounding code is correct, so that the buffer, receive, _sock and result variables are correct.

I might as well archive the project and attach it But anyways. I don't mind
private System.Byte[] buffer=new Byte[1024];
private void SetupReceiveCallback(Socket _sock)
{
AsyncCallback receive=new AsyncCallback(OnReceive);
_sock.BeginReceive(buffer,0,buffer.Length,SocketFlags.None,receive,_sock);
}
private void OnReceive(IAsyncResult result)
{
try
{
Socket _sock=(Socket)result.AsyncState;
int stop=_sock.EndReceive(result);
String str=System.Text.Encoding.ASCII.GetString(buffer,0,stop);
MessageBox.Show(str);
process(buffer,stop);
SetupReceiveCallback(_sock);
}
catch
{
MessageBox.Show("Out");
this.Close();
}
}
So?

I am trying to figure out how to list all user accounts that exist in the SAM. I have figured out how to get the account name of the owner of a file, but not a list of all accounts on the machine.
Thanks for helping.

My C# book reads:
In this example, the two-parameter constructor executes before any code in the body of the one-parameter constructor (though in this particular case, since there is no code in the body of the one-parameter con-structor, it makes no difference).
By following through the code it seems that the one-parameter constructor is called first, which in turn calls the two-parameter constructor, so, is this an error, or do you think it might have another meaning?

namespace TestConsole.TestClasses
{
class Car
{
private string description;
private uint nWheels;
public Car(string model, uint nWheels)
{
this.description = description;
this.nWheels = nWheels;
}
public Car(string model) : this(model, 4) { }
}
}

Hi Jon,
it is the one-parm constructor that gets invoked first, but it is the body of
the 2-parm one that executes before the (empty) body of the 1-parm constructor.
Same prder as the code that says: Car(model) needs "this(model,4)" before it does the "{ }".
BTW if you use <pre>some code</pre> you can show code snippets
that preserve their formatting (mainly indentation). That would be much more readable.
On the other hand, if your post contains special characters (especially <)
they get eaten by the HTML interpreter, then you better would check the "ignore HTML tags"
checkbox below the textbox (but then thr pre command will no longer work either).

Thanks for your reply.... you mean this is readable?
class Car
{
private string description;
private uint nWheels;
public Car(string model, uint nWheels)
{
this.description = description;
this.nWheels = nWheels;
}
public Car(string model) : this(model, 4) { }
}

Hi Jon, you're welcome. Yes, it is much more readable like that.

If I may add, I like to put <code> and </code> tags inside the <pre> tags. Just colors it up nice
