i am declaring two classes
class A
{
virtual void abc()
{
}
}
class B:A
{
override void abc()
{
}
}
now i create an object for both the classes
A d = new A();
B e =new B();
d.abc();
or
e.abc();
how can i call the the function of class a , using the object of class b

Nah.. It would be d.abc()
Since the in Class B.. the function of Class A is overriden.
I hope I am right

If i am not mistaken, ((A)e).abc();
But I got to wonder, do you ever learn anything from the questions you posted, or do you just want the answer of each question and that's it?

That would seem to be the case. She doesn't seem to be willing to do anything to help herself. All I can conclude is that she's either lazy or unwilling to think for herself.
Deja View - the feeling that you've seen this post before.

What I don't get is that the questions are often so devoid of meaning that it's hard to believe she's actually writing something with this stuff. It just seems to be random.

I am afraid that you are. When calling a virtual method, the actual type of the object is used, and casting the reference to a different type doesn't change the actual type of the object.

Why do you start a new thread, instead of continuing in the same thread?

You can't.

At this point, I'm assuming that you're trolling. I can't think of any other explanation for the stream of posts that just keep coming, regardless of how many people urge you to learn to do some basic research.

I would have to agree with you on this one. Almost all of the posts are trivial in nature at best and all could have been answered by reading a single introductory book to programming and .NET.
Given the large amount of questions posted like this in such a short period of time (843 in 6 months, at last count) and the number of people that have responded by actually providing an answer and/or telling her to go out and pick up said introductory book, any way to ban this account or at least put her on probabtion of some kind? (It might not be worth it since she could always just open another account, but it might serve to get the message across and would be one small step to help everyone here not waste time cralwing through these messages.)
By the way, according to her profile, her homepage is the Visual Basic/VB.NET Fourm.

Hi,
I need your help for some sporadic problem that I got during starting new process (C# 1.1).
when I 'm starting new process on remote machine (using remoting), my process starts properly and launching an external application, but from some strange reason it does not exit , and the CPU is growing almost to 98% despite the fact that the application I run via this process finished its job.
Please see my code below:
Code: ( text )
proc = new Process();
proc.EnableRaisingEvents = true;
proc.StartInfo.FileName = m_AppExeName;
proc.StartInfo.WorkingDirectory = m_AppFolderName;
proc.StartInfo.UseShellExecute = false;
proc.Start();
10x,
Lior

Hello,
Two Point's that come in my mind:
.)
Are you holding the reference to the Process all the time or are you disposing it proper.
You could use a 'using'-block for that:
using (Process proc = new Process())
{
proc...
}
.)
Why are you setting the 'EnableRaisingEvents' to 'true'.
Are you handling the 'Exited' event somewere?
All the best,
Martin

Thanks for your quick response
I'm holding a reference to this Process indeed.
In addition, I'm using the 'Exited' event later in the code in order to get notified
when my process finished its job (notify the client).
Do u think it can cause this problem??
Thanks,
Lior

I'm really not sure about that.
Give it a try without holding the process and the delegate.
All the best,
Martin

Add a reference of FaxCom.dll in your project...I haven't used it but i think u will find all the required methods and classes in the dll...Try google

if i declare the function in the class as public static .i now no need to create the object , like
class abc
{
public static void abc1()
{
}
}
class def
{
void abcbd()
{
abc.abc1();
}
}
what will happen if i declare the class as static?

Open www.google.com[^].
Type "C# static class".
Hit the "Google Search" button.
Click on first link.
Read second paragraph.

In this case the result will be the same. Because when you declare a method static in a non-static class you can call it without creating new object. If you declare class static, you're declaring only static methods inside... For more search google...
