Thanks mate. I posted this question here by mistake. I appreciate your response and I've moved the question to ASP.NET Forum.
Parallely I'm going through your referenced Link.  Really thanks

Rule 1: Learn to read. At the top of the page, it says: "if you need specific help please ask your question here." and links to the QA forum: http://www.codeproject.com/Questions/ask.aspx[^]
Instead, you posted what looks like your homework in a non-question forum, because you couldn't be bothered to look properly.
Now, what makes you feel that I might want to bother myself and spend time answering your question, when you can't be bothered to ask in the right place?

Rule 2: You don't talk about CodeProject 
How do you know so much about swallows? Well, you have to know these things when you're a king, you know.

And Nice revert back @Brent Jenkins. 
Please let people think what else they want. It's upto them how they represent themselves to others as it describes their atticates which matters equal to technical strength.

We're a bit like Fight Club here and have similar rules:

0 - Well structured question! Well done for that!
1 - this forum is the Lounge where programming questions are not allowed.
Suggest you go to quick questions and ask this question again.
but as a really quick answer, you pass interfaces rather than objects so that you can pass any object that implements that interface - especially useful if you are unit testing, as you can pass fake objects that implement the interface.

Regarding your answer, Thanks a lot for that. I got the point. I agree that was a stupid question but looking at someone else code in such a large application confused me. Thanks

There are many reasons for passing in an interface into a constructor. One reason is to be able to supply different implementations into the constructor, which is particularly useful when you want to unit test your code. Rather than having to pass in a concrete implementation, which might rely on things that are difficult to test, you can use a mocking tool to create a mock of the interface and pass this in. This makes it easy to do things like set up verifications.

Hi,
I am developing HRMS .NET WinForm application using C# and DevExpress.
I want to know what's the best way practice to include reports in my application?
Should I use the RDLC, Crystal Reports or the XtraReports from DevExpress?
I want the reports to be physical files (in \Reports) and not embded within my application then I will browse it using a database table so it will be easy to add new reports whenever its required.
Thanks

The respective producers of each reporting tool say it is a best practice to use their suite.

All three would support that scenario AFAIK.
I'd recommend a fourth option; exporting to HTML based on a template, since that is the simplest option that meets the requirements.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
So please, edit your question and provide better information.

By leaving 2 of the columns empty.

Hi, I started converting the program last night up to 2AM (5PM here as of writing this).
I feel like I'm consuming much time in thinking and Trial and Error, I really need some help.
I bet this is easy for those who has experience in C#.
Take a look at this sample project (this project is a C# console, socket programming (telnet) ).
http://www.codeproject.com/Articles/19071/Quick-tool-A-minimalistic-Telnet-library
and then, what I need to do are the following:
1. Remove the user and password submission, since I'm going to telnet my microcontroller and
that microcontroller doesn't have such security. In the sample program above, if the ip
you are going to telnet doesn't have user and password requirement, it will return an exception.
(Actually, I have already done this, I modified the C# console sample
program, and magically it works. look at my code below)
static void Main(string[] args)
{
TelnetConnection tc = new TelnetConnection("news.thundernews.com", 23);
String prompt = "";
while (tc.IsConnected && prompt.Trim() != "exit" )
{
Console.Write(tc.Read());
2. In my windows form, I have there BUTTON1, and whenever you click that, it will CONNECT the program to the
desired ip address via TELNET. My problem is, I will consume much much time in thinking of this. I don't even
know yet how does my edited code posted above work.
3. I have too a BUTTON2, if you click this, the C# program will send a string from any controls, like textbox.
(I think, no need for this to answer. tc.WriteLine(prompt); <-- that code will send byte to the server)
4. finally, as soon as the BUTTON1 connect is clicked, the C# program will auto receive any incoming byte from the server,
and the program will put the received bytes into some controls, say.... RICH TEXT BOX.
I have tried my best to convert this C# program (which works 100%, but I really need a winform sample) to winform.
I just need a very example and I will take care of the rest of my project.
One of the things that make me go crazy is where should I put the WHILE LOOP part from C# console to C# winform?
That's all. Thank you so much in advance!

You don't.
Instead, Winforms apps rely on events to "decide to do something" instead of just "waiting for it to happen". It's a totally different execution model, and you can;t just "pick up" console based code and expect it to work as a winforms based application: the basic processing stuff my be the same (or at least similar) but the way the whole program is "hooked together" is very, very different.
For example, in a console app, you are likely to print a prompt, and wait for a user to enter a filename - and nothing else will happen until the user presses ENTER to indicate he is finished. That doesn't happen with WinForms apps: the user can type, edit, go do something else; a timer might "chip in" to make the code do something at a specific time; your Socket might signal "I got data!" and your code process it.
You can't just "convert a console app to WinForms" - you will have to think about how your console app is working, and what it is doing, and then consider how that fits into the Winforms execution model.

I'm coding for Windows Forms. The teacher has only gone over arrays so far, but likes arraylists better. Using arraylists b/c can mix types.
Out of range error from this line:
subtotal = (decimal)subList1[2] + (decimal)subList2[2] + ... (decimal)subList5[2]);
(What gets added previously is a decimal.)
If my menu item 'AddtoCart' has not filled all arraylists (i.e. 5 times) I get the error. Thinking the ones not "given" a value = -1. I don't care to use List<>, etc. as this teacher can get vy prissy.
I just want to change the values that I think are -1 to 0 so addition works. I can't pre-load anything due to how arraylists get 'loaded', obviously. I could Replace the last element: [2].
But I don't know how to loop b/c I can't use a variable such as i in the name of the arraylist itself. Been high and low online for a solution...
Thank you,
Mac

The out of range exception indicates that there is no element at 2 in one of your lists. Put a breakpoint on that line by pressing F9 and debug your application. Take a look at the size of each one of your lists.

Your teacher is an idiot. Arraylists are seriously out of date, simply because you can mix types, which means they give runtime errors instead of compile time. That means that it is more likely that a problem will get through to production than using a List<T> which insists on strong typing and doesn't need you to cast the variables.
But in this case, I'd use an array of decimal values instead of a List or ArrayList: unless you are adding items dynamically (at run time) and don't know the number of items in advance.
The error is probably because you are using "magic numbers" - the hard-coded "2" in your code - instead of using a loop to get the values.
Go back a step, and think how you would use a loop to access an array - I'm sure that your teacher has covered that - and then look at the whole of your code (not just the one line you show) and try using that method on your list.
