This is more theoretical than anything else and I have heard variations.
Generally you have a class:
public class employee<br />
{<br />
string employeeName;<br />
int empID;<br />
<br />
(Some other methods)<br />
<br />
}
In the using class, say company you could just reference the employeeName through its class such as employee.employeeName. But if you need to continuously reference that name do you want to do this or do you want to do:
<br />
public class company<br />
{<br />
string employeeName = employee.employeeName;<br />
}<br />
Then use the local, or is it better to alway just call the employee.employeeName.

Oh, I see. Well, if it is something as simple as accessing a field then I don't think there is much advantage in saving it locally. Also, you really ought not to be accessing the fields of a class directly from outside the class in which it is declared.
If you are accessing a property then there possibily is an advantage is saving it locally. The property could, for example, have to do a look up each time it is called - That takes time, so it would be better if that didn't have to happen.
Often, I'll save the value locally for improved readability more than any other reason. All those excessively long lines can be difficult to debug, especially if you are stepping through code and you keep stepping in and out of properties in one line of code.

Thanks,
It really was a stupid question, one of those where for no reason you just wanna get an idea since you have always done something in a way but never wondered if it really made any difference. Kinda like stings and string builders. Truly makes a difference.

Hi,
How to invoke web service methods in C#.Net?
Thanks in advance
|
|
|
|
|
The question is a bit short to really understand your problem. But I will try to guess here.
The most basic operation to be able to use a webservice in your application is to right-click on the project and choose Add Web Reference. There you browse to the webservice, give it a good name and select OK.
After that it's just simply a matter of doing something like this:
ServiceClass service = new ServiceClass();<br />
object someResult = service.SomeMethod(someParameter);
The service class is strongly typed, so you shouldn't have much trouble finding out how to call the service and what to pass and what you get in return.
Hope this helps

When you posted this and you got the warning that your message was very long and you should consider cutting it down, did you actually pay any attention?
I'd love to help, but I'm not going to read through all that. If you have a specific question then we'd love to help.
One quick comment. Your first method is a bubble sort. What was wrong with the built in sorting mechanisms in .NET?

I've started helping out here on somewhat of a regular basis. I've noticed that posters rarely surround their code with pre tags. Instead, they use the code tag or no tag at all. This makes it hard to read their code.

The problem, and it's something you should take up with Chris if you want anything done is that the pre tag doesn't appear to be intended for code snippets. I'm not sure what to rename it as to make what it and the code tag are intended to do more clear, otherwise I'd've posted to the suggestions board a while ago myself.

Yes Colin i saw this warning about long code and i appoligize for that.
May be you are right about bubble sort and it's not be included in code.
My question how to rebuilt this code in "structs". I began programm 4 months
ago and i don't have a lot of skills. But i have to rebuilt this to struct.
i want to do 3 or 4 structs : " Card", "CardDeck", "Hand" and may be "Game".
Card and CardDeck i think allright, but Hand that initializes 5 cards prints
and replaces old card to new not working, i don't know what to do.
May be somebody know source code or links to this.
Tnanks...

You could have a look at my article [^]about scoring cribbage hands.
Cribbage is a fundamentally different card game from poker, but I show you how to find pairs, flushes and straights...

Hi,
From database i m getting value like 1,2,3,4,5,6,7,8,9,10,11 upto 9999.
these value i m displaying in combobox
but i want to display like this
if it's 1 to 9 then i have to display 0001.
if it's 10 to 99 then i have to display 0010 upto 0099.
if it's 100 to 999 then i have to display 0100 upto 0999.
if it's 1000 to 9999 then i have to display 1000 upto 9999.
help me it's too urgent.
thanks

Well I haven't worked with comboboxes but I believe they have two properties, datatextfield and datavaluefield. If so you can do this
combobox.datatextfield = datatable["field"].ToString().PadLeft(4,'0');
-----

|
|
|
|
comboBox1.Text = comboBox1.Text.ToString().PadLeft(4, '0');

Gents,
I have a combobox that contains operations (Range, >, < and =). The user should select needed opertion to process some text fields. How can I get the operation selected to put in the if statment. For example, here is a '>' is selected:
if (DoubleA > DoubleB)
I want to do it in efficient way because i have many comparisons based on user selection.
Thanks for your assistance in advance.

A little OO thinking helps.
abstract class FilterBase
{
public abstract bool PerformOperator(int a, int b);
}
public class EqualsFilter : FilterBase
{
public bool PerformOperator(int a, int b);
{
return (a == b);
}
}
The above is an example of the strategy pattern.
Each item in the combo box is assosiated with a specific instance of the Filter class (or rather one of its derived varients). Because the FilterBase class cotains the methods needed, that is all you ever need to reference. Once set up the rest of the code does not need to know anything about each of the specialised classes.
