Hello.
I might be wrong, but InnerText will take all the text inside a node.
for examlple
<xml>
<element1>
<element2>ABC</element2>
</element1>
</xml>
the InnerText of element1 will be "<element2>ABC</element2>"
while value will only fork for childnodes
could this be right ?

That is what InnerXml does. InnerText get the values of the node and all child nodes.
I'm not sure if it ignores white space if the node only contains white space and children. The InnerText of element1 will either be "ABC" or "\r\n ABC\r\n".

Console.Write(".............");
x = Console.Read();
Console.Write(".............");
y = Console.Read();
When using above code, the second Console.Read() has been done automatically caused by the "Enter key" of the first one.
How can I solve this problem? How can I clear buffer of keyboard??

I am defining an interface to a real-time engine. Based on inputs to the engine the engine may fire events. How do I build the code so that the eventhandler is on the other side of the interface from the engine? That is, my subscriber(s) is external to the engine. Seems to me I have to declare something in the interface specification.
Thanks.

If you are already defining an interface, events arent necessary. You simply call the methods on the interface and let the implemeter handle them. IMO better than the event approach, and alot faster due to direct calls. 
Events in an interface is normally so the interface can 'notify' to the interface user.
|
|
|
|
|
Consider this diagram:
user <- interface -> engine
Based on your last e-mail, the target of the event within the engine is on the interface. How is it that the user is notified?
|

I think he's confused about your use of the word interface - he's thinking of an interface such as IDisposable, or ISerializable (though obviously defined by you), and it sounds like you mean interface as object layer that hides the engine.
Off the top of my head, I can think of two ways to do this:
1) Cascading events - When the interface is loaded, it subscribes to events in the engine. When the user connects to the interface, it then subscribes to events in the interface. When the engine raises the event, the interface gets notified to it's handler. It then raises the event the user subscribed to.
These cascading events will work, though performance may be a concern to you. It wasn't in an app I'm working on (at least in this area), and the events needed to be bubbled up quite a few layers, with each layer doing something with the event, so this mechanism worked fairly well.
2) Have a method defined in your interface that takes in a delegate as a parameter of the correct delegate type to the event you want to subscribe to. This interface method will use this delegate to subscribe to the engine event. When the engine raises the event, the user is notified without the interface getting in the way.
<br />
public void ConnectEvent(EventHandler h)<br />
{<br />
engine->TheEvent += h;<br />
}<br />
<br />
...<br />
interface->ConnectEvent(new EventHandler(user_EventHandler));<br />
I did something like this a while ago, but I don't remember why or how well it worked out.

it's used for debugging. You put one prior to where you have a peice of code that isn't working. When the program gets to that point it stops running and goes to the IDE where you can step through the code one line at a time to see what's going on.
