public interface IncDec<br />
{<br />
void Increment();<br />
void Decrement();<br />
}<br />
<br />
public class MyIncDec : IncDec<br />
{<br />
private int x;<br />
public MyIncDec(int x)<br />
{<br />
this.x = x;<br />
}<br />
public void Increment()<br />
{<br />
this.x++;<br />
}<br />
public void Decrement()<br />
{<br />
this.x--;<br />
}<br />
}
Part 1: Implement a class which can be used to measure how long each invocation of the Increment and Decrement method takes (in milliseconds) and prints out this information. The class should fit in more or less transparently with existing clients of the IncDec interface.
Part 2: Imagine you need to do something similar (timing of method calls) for many places in an application. What other ideas come to mind, e.g. could you propose other ideas for getting timing information more conveniently?
I got this question need to answer, it is simple, just something confused to me. hope anyone can help me.
btw, what "The class should fit in more or less transparently with existing clients of the IncDec interface.
" means?

I suppose your teacher (this is homework, right?) means to give you a hint. If you create a new class that inherits MyIncDec and call the base classes methods, you can use this class instead of the orignal and have a place to put your performance timing code without disturbing MyIncDec's existing users.
Standards are great! Everybody should have one!

its not homework, I konw its simple.
thanks your answer. do you think the new class inherit from interface or that class. which one is better

Hi,
this is a stupid assignment. In order to make it a realistic problem, one would need to measure a method containing hundred or more instructions to start with, not a single increment.
The code required to transparently measure the duration of an increment will probably use a derived class, virtual methods, and a StopWatch. As such it will be much slower than the original increment itself, so the result is bound to be inaccurate (on top of being utterly irrelevant).

Hi Guys,
How can we set the web browser control for example if the user load a .doc file on it then it cannot be edited? I mean, the user is not able to change file that has been loaded in the web control (example format is '.doc','.xls' etc..).
I'm trying to counter this kinda things, but sad to say, I did not find some hint or solution on how to do that.
Thank you!
regards,
erson

So far as I know, you must set a password for "Change Document" in word during saving. Wrong password means not able to edit the document.

Why are you posting in the C# forum then ?
This is a TON of work. You would need to basically write a framework that allows the user to create their own controls and databind them. I would say it's almost certainly beyond you.

datagridview shows the item information and at the button click a new form(Add Item) opened by which user can add the item information.

Its not Like that.........
datagridview is on a form named ViewItem and we want to update this datgridview through a button that is on another form name AddItem...
|
|

In dataGeidView set property Modifiers to true and in form AddItem bind datagridview which is in form ViewItem.

You are right,sorry it was my mistake to set Modifiers to true,I wanted write Public but not true.

Use delegates to cause events to happen between forms.

how can i use the delegates.tell me in detail or any example...

I like to give just the keywords. Anyone with any chance of ever becoming a programmer, should be able to type 'C# delegate' into google and find tons of articles to read.
