keyword Programs

I understand how "new" & "delete" work. "new" creates a object, pointer, etc. & "delete" deletes them. But I don't use them very much cause it forces me to use pointers when its much easier to overload or create a template.

I have experience with Java & C++, so when are the best times to use these keywords in any programming language?.

There is no such thing as the best time to use those. It has to do with the design of the programming you are trying to write.

Typically you will use them when the data requirements for your program are variable enough that you need to create items on the fly. When you don't have pre-knowledge of how many things you have to manage (which, typically is in most programming).

The only obvious statement with those languages that don't have garbage collection if you use a new, make sure you have a matching delete somewhere.

In my case, I already have like 90 credits obtained in Europe, hopefully most of them will be transferred, but I can`t go to Oakton or Wright because they only have Associate programs.
I am considering online courses well. Once again, the keyword is CHEAPEST programs. Thanks!

Are you an international student or paying out-of-state tuition? If so then all of the universities are going to be expensive.

If so then UIC will probably be the cheapest in the Chicago, if you are willing to look outside then I would imagine that Trinity and Northern Illinois may be even cheaper.

the keyword is free….i can barely afford food ha

Check out AVG, they have a free edition.

I have a list of 100 keywords in Google Adwords. I want to know if there is a program that I can use that will tell me what page in Google each of those 100 appears (or does not appear). So for example if I have keywords: dog, dog collar, and dog food, I want to know what pages in google they appear: ie pages 3, 15, and 99.

Thanks!

Keywords definitely helps you get into good positions in search engines. The examples you have given are short keywords and it would take some time to get the postions,, it means it depends on the keywords if they are long tail or short tail.
If you provide info on your web site and the keywords it would be much easier to analyze the site.

A class that is defined with the "sealed" keyword cannot be inherited. So if I define a class as follows:
sealed class A
{
public int DATA;
}

This would fail to compile because class A is "sealed" and cannot be derived:
class B : A
{

}

The "this" reserved word returns a reference to the object in the current context. Look at the following example:
sealed class A
{
public int DATA = 25;

public int Add100()
{
// These two lines are equivalent
this.DATA = this.DATA + 50;
DATA = DATA + 50;

return DATA;
}

public A ReturnMe()
{
return this;
}
}

In the above example "this" returns the current object and it is of the type A. You will notice two equivalent lines. this.DATA and DATA point to the same thing. You will also notice in the ReturnMe method the object returns a reference of itself. This is not practical but you normally use the "this" reserved word to pass a reference of yourself to another object.

You could see it like this:
public void btnLaunch_Click(…)
{
frmDialog dlgEdit = new frmDialog();
dlgEdit.Tag = this;
dlgEdit.ShowDialog(this);
}

In the example there I create a dialog and pass a reference of the current dialog to the Tag property on the new dialog. That way frmDialog can modify members on the class that loaded it.

Hi all!
I’m a beginner for SQL Server 2000. But, I’ve learned exception handling in Oracle 8i. I know the meaning of the exception handling but I can’t able to write a programs in SQL Server 2000. So please tell me the simple program for exception handling. And tell me, what are all the keywords or functions to be involved.

There is no error handling in SQL Server 2000, but there is in SQL Server 2005/2008:
try…catch
