Hi Leslie,
Thanks again for your comments.
I did originally want to use the Visitor pattern but I will extend the application with more elements and I think that is where the Visitor pattern falls down. I did look at another pattern, a quick search on Google tells me it was called Acyclic Visitor, however, it didn't tick all the boxes either.
Regards,
Adam

How can i make good s-box easily (against linear and differential attacks)? If i used prepaid one that may belongs to someone or standard ciphers then it would be plagiarism right? So i need to make own s-box (8 bit input, 8 bit output (16x16)). Please Please suggest me any way to decide it. Thank you.

What's an s-box?

The s-box in cryptography is named like Substitution box (a.k.a substitution table).

Ahh..out of my area of expertise then.

Use standard ciphers. Fiddling with your own substitutions might accidently introduce weakness. The framework provides a whole bunch of CSPs you can use royalty free anyway - theres very little reason to implement your own cipher, and lots of reasons not to.

We have a web app that is developed using VB, ASP and SQL SERVER. Some parts (10-15%) of the web app are developed using asp.net 1.1.
Now, we want to:
- move one of the modules say CRM to asp.net 2.0 that is written in VB and ASP.
- support the CRM module written in VB and ASP until the re-written module using .net is ready to use.
- incorporate any changes happen in old code into new .net code immediately.
- Leverage the power of AJAX AND Windows workflow foundation
Existing system:
- The CRM module uses others DLLS written in VB and vice-versa.
- We have all the classes required for CRM DLL developed in VB. Example :> Let say we have a biz object class which contains all the biz attributes (properties) as well as methods and called from ASP page. We also have a corresponding data object class which has only corresponding methods as Biz object and interacts with DB and return the results to Biz object.
- We have all screens required for CRM developed using ASP and JAVASCRIPT.
As a .Net senior developer, my responsibilities include:
1 - Create all CRM VB classes in C# to improve performance, better use technology, and remove redundancy
2 - Analyze the classes and Apply design pattern wherever possible
3 - There must be not any problem when the CRM module is completely re-written as the new .net dll for CRM should be able to call other VB DLLS and vice versa.
4 - All pages for CRM module must be re-written using ASP.NET, AJAX and Windows workflow foundation
Need suggestions:
- Should I do requirement analysis again or it is not required since the requirement is already there.
- Should I create all the VB Biz classes as it in C# and then apply design pattern wherever possible.
- Should I create the Net wrapper DLLS for all the VB DLLS that need to be referred by CRM .Net DLL and vice-versa.
- No problem if I use AJAX AND WORKFLOW
Please let me know if you have other suggestions.

Hi guys!
Can anyone point me to a good tool that would help to generate a structured list of functional requirements (features) such as found in software requirements specifications (SRS)? I can type all that in Word, but it's a hassle and I'am looking for a more automated way to do those lists.
What I am looking for is an app where I could:
1. Enter a new feature/requirement. This gets an ID, etc.
2. Enter some other requirements. The list is growing...
3. Link requirements, so they are visible in a tree-like structure, say REQ-3-2-2 depends on REQ-3-2-1, something like that.
If I could export that to Excel or generate a report it would rock.
I saw a web based application once which allowed the user to create a list of requirements like this and do some (interactive!) mockups, I believe I got it in CP newsletter a few months ago and I can't remember the name, neither I have it in my mailbox.  I know it started with "S" (not very helpful, eh?).

Hello everybody!
I'm designing an application that generates some results after doing analytics processes. Then the results can be saved into different formats (like TXT,XML,EXCEL,etc...) and with different formats, deppending user options and the format of data file selected.
How do you think is the best way to dessign this part? I'm thinking about using the Factory Pattern, about creating and passing the data to each especific class (one per each file format), and a Decorator pattern that adds the optional data configured by de user.
But I don't know if I'm thinking in the best way. Could you bring some ideas?
Thank you.

I produce XML, then XSLT can transform it to other formats, such as HTML and CSV.
Excel can read CSV so don't bother writing XLS directly.
|
|
|
|
|
Thanx for your reply. Y will consider this option.
|
|

Keep the analytical data in Director.
Give format to your data using Builder.
Builder pattern.

Please let me know what is a properties file and what does it contain.
I have to create a propeties file which I would be using in my program. Please help me how should I create a properties file.
thanks.

If you don't know what a properties file is, how do you know that you're supposed to make one?

Is Extreme Programming methodology and Incremental development methodology same?
Are both of them considered as a agile methodology?
Can i use term agile methodology for incremental development approach or not?
I am confused about one thing. In XP, a prototype is build over n over until its complete. Where as in incremenatl development, each module/prototype is developed seperately and added together by the end.
So which one is it really. Quite confused about these. I think they both are same. Please let me know the right answer.
Thank u
Julia

ThankU-help me please...

Have you thought of using Google. They do have a rather good search engine able to find almost anything you ask of it.
If your exam is coming up, you had better get your skates on, and google is awaiting your key presses.
Unless you need a tutorial on how to use google.

No google is not helping me out. 
I cant find difference between incremental development and extreme programming. I think both are same and both are part of agile methodology. They just have two different name and what do you think gentleman ?
thanks
