I have to develop a tool in visual Studio about a Chemical Analysis Tool kinda similar to Turbo Tax Software.This tool asks the user some questions about the chemical composition of the product and some production data during the run time.On the basis of the values entered by the user,it does some calculations(some Big calculations) on the back end and prints/pdfs a report which displays the total environmental impact of that product in terms of green house gases,waste,water consumption etc.
So,according to my research online,one way would be to store the data entered during run time in a database and then use Crystal Reports to generate a report.
Another thing I can do is to create some kind of Quiz engine which I still have to figure out how to do.
I am wondering if I am thinking in the right direction or there is some other way to do it. I will really appreciate any help on this one.
Software Used: Visual Studio 2010, C#
My suggestion:
Use MS Access for the backend and Crystal for the front end. Why Access?
Because you can easily develop your data entry forms (including drop-down boxes, data validation, questions that depend on answers to other questions, etc.)
You can query your data with standard SQL to do all your computations.
You can write your own nonstandard procedures.
Once Access is done with gathering the data and making the computations, you can output the results to a Crystal Report, an Excel file, or even use Access's Report forms (I don't recommend this, personally. Not enough customization and too ugly for my tastes.)
(I'm going to make this question a Favorite. I want to see how other people answer it.)

So far in my use of objective c and cocoa, I have made some simple OSX apps that make use of some of the basic apple UI elements such as NSButton, NSTextFeild, NSView, etc. However, now I find that I'm wanting to add parts to my programs that don't fit so squarely within the given UI elements. ie. in a program I'm writing now, I want to create a checklist in which users can enter new elements, check off elements to delete them, etc. all with a custom UI. My problem right now is that I don't even know where to start looking for the information I need to learn how to create more advanced things like this, or what to search for to start finding information. Could anyone set me on the right track as to what information I should be looking for and where I can go to find it? Thanks.
You'll probably want to look at Cocos2d or even OpenGL. I'm guessing though that this may be overkill for your solution. You might also be able to override or extend some of the base UI elements.
If you're new to Objective-C and Mac OS programming, I would recommend taking it a bit slower with this. Often we developers dream up huge complex interfaces when really, just a basic, stock interface would work just fine for our users.
For your first release, keep it simple and just ship some code in short time. Then work with your users and see how they really want to work with your app and go from there.
Good luck!

I've a book review site, where readers can write reviews about books, other users can post comments. I wanted to know following things automatically whenever new review publish or new comment published.
(1) whether book review is positive or not? How much % positive / negative?
(2) whether comment made by particular user is positive or not? How much % positive / negative?
(3) I want to read Tweets about particular book and wanted to check whether the tweet is positive or not?
bottom line, I want some tool suggestions (opensource), which I can use for my website. Website is written in PHP and I'm looking for some semantic analysis tool which I can customize to meet my need or which best fit my need.
if not, I want to know if its easy to build one with minimal requirements. I know PHP, Perl, Shell Script. I can learn Python. I know C++, Java may be right language to start from scratch; but don't have much experience.
There is an open source semantic analyses engine incubated in the Apache Software Foundation, currently, called Stanbol. It provides APIs to interface with it over HTTP as well as through a Java API if needed. It's pretty advanced, but generally speaking if your needs are simpler you can always try some SaS solution like uClassify.
In response to your first request, I'd suggest you create a form where the user has a voting option (such as a x/5 star rating, etc) then you would calculate the average from all of the reviews.

I want to scrape reviews about various products and things in the web, how can I do that. There is a company called searchreviews.com, they do it, I want to know how they do it.
They get a page's HTML then parse it, targeting whatever information they need.
It's really awful, because it depends on the DOM of the site you're scraping, which can change at any time, in both trivial and complex ways. I've worked with companies that have scraped (legitimately) various types of sites, and it's horrible.
mechanize or watir or rautomation are related gems that might help you here.
I've done this very often for various clients, and most of the time a site that gathers reviews is pretty well structured, so scraping isn't too hard. Look at Yelp.com for example. I built a routine in screen-scraper that searched zip codes in the client's area, used the filters to hone in on the desired business types, and makes a list of unique results (since the zip code searches could render duplicate results). From there I hie each unique URL. The reviews are pretty easy to parse with just RegEx, and some page iteration.

I need to use a wireless barcode scanner to scan a barcode and send the data to the application located on a computer and then the computer processes the data given.
but I don't know how should I make my application listening for the barcode info over WIFI,
how can I do that?
and can barcode scanners send data to a web form automatically? (GET)
and another question , do you think QR-codes are suitable for warehouse management?
thank you
That really, really depends on the interface that your scanner provides. As long as you are both connected to the same WiFi network, you can probably just access it via its IP. But how you specifically connect will vary between scanners.
About the web form, I doubt it will support that. But again it depends on the scanner. You'll most likely have some method of it PUSHing data.
I think the question you need to ask about the tracking isn't specifically about QR Codes, but rather whether a 2D bar code is what you need at all. Warehouses are increasingly moving over to RFID for internal tracking, and with RFID labels dropping in price they're viable too. If you want to stick to an ink-based approach, what advantage will a 2D bar code have over a basic 1D one in your scenario?
The latter is much easier to deal with, yet does somewhat rely on orientation unless you have a multi-directional scanner. In that case, you'll probably find it more reliable; it's going to be using a laser as opposed to having to essentially photograph and decode the 2D code.

I want to implement a "text" suggestion.
I have a huge number of data, how I can implement an efficient and scalable auto-complete?
Edit 1:
i have a mysql table with one client per row and a 'name' column, i want to create a suggest in order to search client name (like google suggest but instead of queries it is client name) - I have a huge numbers of rows, how I can design an efficient suggest?
When user will start typing inside an "input text", I want to display possible client names
OK, I think I understand what you're looking for and here are some possible solutions for you:
What is the best autocomplete/suggest algorithm,datastructure [C++/C] (the answers are generic enough despite the fact that it's a C/C++ question)
How to implement autocomplete on a massive dataset
Autocomplete using a trie
Algorithm for autocomplete?
Trie based addressbook and efficient search by name and contact number
How do you autocomplete names containing spaces?
Essentially, it seems like you're looking for auto-complete functionality (if I understood your question correctly). Along those lines, the above questions and their answers also provide a lot of references on how to do more complex suggestions (i.e. based on content, semantics, intent, etc.).
This will probably not address your question if you're looking for an algorithm that makes "related" suggestions, e.g.:
"water" may suggest kool-aid, gatorade, vitamin water.
"sea" may suggest ocean, lake, river
