To get answer, be specific with your question.

What it does?
Why or how you say it is slow?
etc

Make sure C:\Drive has More than 1 GB disc Space. Sometimes this will slow down the performance.

With the complete lack of information you've given so far, it's IMPOSSSIBLE to answer your question.
Without seeing your code and a description of how the app works and how it's designed, there's really nothing anyone can say that will be helpful.

We cannot create instance of an abstract class as abstract keyword is an indication to compiler not to consider the abstract class as a type.
If any it is just for initialization of properties/variables of abstract class then that can be achieved by private or protected constructor.
If you declare a public constructor in an abstract class then compiler will not give any errors.

First off, you can't use a private constructor in an abstract class, as you cannot create a derived class from it: the derived class cannot access the private constructor so you get a "is inaccessible due to its protection level" error from the compiler.
And that's kind of the clue as to why you can declare a public constructor: so that derived examples can be used in any assembly or class. Yes, you could use protected instead, and that would work - but it's not so obvious that it's allowed when you quickly read it!

Incorrect; an abstract class is also a type.

Only members need be initialized, and one doesn't need a constructor for that either.

Sound correct. Same does not apply to private methods btw.

I have a form in which i an using tab control.
There are three tabs and in each tab there are textboxes.
What i want to achieve is that when i switch from tab 1 to tab 2. All the textboxes of tab 1 should be cleared.
Is it possible???
I am using Visual studio 2013, .NET 4.5, C#

Check the active index of tab on tab click and set the text box blank.

Why the following code gives me this:
1000000000000000019884624838656
instead of
1000000000000000000000000000000
BigInteger result = new BigInteger(Math.Pow(1000, 10));

I am trying to use Lognormal distribution in one of my projects and require the inverse Cumulative distribution function.
Any help would really be appreciated
|
|
|
|
|

Thank you Richard, I was not looking for a code. using lognormal means that I need to use the inverse of an ERF or ERFC. I know that both are implemented in c#, and was merely looking for some help in directing my search.
