I have a server that exposes some classes through .NET Remoting.
If these classes have events, can the client subscribe them by simply using the usual syntax Event += new EventHandler(...), after getting a reference to the remote object?
Perhaps I'm asking an idiocy.

Yes they can, and that is the beauty of remoting, you can use remote objects just like local ones.
You need to be aware of potential security exceptions though, because when the server fires an event, communication is happening in the opposite direction (when compared to a method call). Specifically, you'd need to set the typeFilterLevel[^] to allow two way communication. And of course, if your client is behind a firewall that blocks all incoming traffic, it's not going to get the events.

Thanks for your reply!

I thought that, when you get an instance of the remote object, the network connection is kept open until you destroy it. Am I wrong?

Yes, but you need a different socket connection for events, as the role is reversed i.e client becomes server and server becomes client, because it's the server that initiates the call.

Did you set the forms KeyPreview property to True?

I have an array of bit values - well actually a bool array, 8 elements long. How can I convert this into it's byte representation?
So basically, I want to do a binary to decimal conversion. How can I do this?
/\ |_ E X E GG
|
|
|
|
|
Create a BitArray from the array of booleans and use the CopyTo method to store the value in an array of byte (with the size of one).
---
b { font-weight: normal; }
|
|
|
|
|
OK Thanks. I found a nice library on this site also...
/\ |_ E X E GG
|
|
|
|
|
If it's just an 8-bit to byte conversion this will do the job:
byte value = 0;
bool[] bits = { false, true, true, false, true, false, false, true };
for (byte b = 0; b < bits.Length; b++)
{
value <<= 1;
if (bits[b])
value |= 0x1;
}
This will also work if you change byte to int and increase the array length to a maximum of 32 boolean values

ok next q ... how do you access inputs into a constructor
within the base class?
my base class constructor:
protected int commonID; // this is common to all object
public BaseClass{
console.write commonID; // or something that accesses id
}
my sub-class constrictor:
public myClass(int id)
{
commonID = id;
}
but when I instantiate "myClass", before it sets commonID, it goes
to the BaseClass constructor. But commonID is null cause it hasnt
been set.
So is there a way for me to get "id" into the baseclass? or get commonID
set?

Here are your two constructors rewritten:
public BaseClass(int id)
{
commonID = id;
console.Write(commonID);
}
public myClass (int id) : base(id)
{
}

public BaseClass{

public void DoOtherThing {
console.write commonID; // or something that accesses id

sub-class:

}

But with this code the purpose of having the base class is somewhat lost as your method requires the subclasses to specifically call DoOtherThing() rather than properly inherite the behaviour of the base constructor.

ADD button is the last control which i click in my page, after I click ADD button if I refreshed the page again ADD buttonEvent is being executed.I don't want this. How to avoid last event from execution when page is refreshed.

I think that's a standard behavior of Internet Explorer so that should be impossible to achieve your goal. But you can put a hyperlink to itself in each page and click it instead of click "Refresh".

Workarounds
1. You can redirect user to someother page after clicking add button. Like "Thanks, values saved" is displayed on that page.
2. You can set an session variable, And increment that value, so if that value is set to 1, you can stop the value from entering into db.

I m using dataGrid control in my application. I want user to add records using Data Grid. Right now my Grid has 5 columns. Problem is that if user fills only one column and click add button, Grid does not add that row. Infact if i click on some other control that row from grid just disappeared. But if i fill all colums then a blank row appear down that row. and now if i click add button, this row will be added.
Now i just want a row to be added if i only fill one column. What should i do?

Hello,
This is because the new row has not been committed in the datatable/datasource which you are using with DataGrid. You can write code in CurrentCellChanged event handler to assure that the changes you made in the datagrid are saved when you leave the cell.
HTH. Cheers.
