I am thinking of making a dictionary application with some changes to suit my needs.But the problem is that I can't figure out how to get the word-list with their meanings.Any idea what I can do?
I found a word-list but it just had words not their meanings.
Edit- I am unable to add a comment.
Though I found this:
http://wordnet.princeton.edu/wordnet/download/
I am trying to see if I can use it in my app.
it's a bit generic question. Are you thinking to store all words in a database with their meanings? For example I imagine you could have two tables ( at least ), word and meaning, meaning has a FK to word so you could have multiple meanings for the same word.
is this ok as starting point?
You basically should search for an open dictionary (check the license carefully!) you can access through an API or download a set of data to use it offline.
This sites should be helpful for a start:
Wiktionary
Open Source Dictionary Downloads

TL;DR: I want the user to be able to input text, which is then written to an external file, which then can be called later based on position in the file. What's the easiest way and form to read and write a list of strings to?
Very amateur question, but I can't seem to find an easy anwer on the internet. If I'm missing something obvious, please redirect me. I am writing a very simple program in which the user can input a string which is then written (added) to an external file, from which later a string can be called based on the position in the file. I found things like JSON, Resource file, SQL DB... Problem is that due to my lack of programming experience I have no idea what's the best option to look into.
Example of what I want to achieve:
User inputs strings 'Dog', 'Cat', and 'Horse' into the textbox. Each of these strings are added to the external file. Lateron, the user calls the 2nd number on the list, to which the program returns 'Cat'.
Thanks!
If you already know the kind of data that will be saved I recommend using XML Serialization. This lets you save and read your file very easily. The linked example is from Microsoft and shows a dataset being serialized. If you want to save a generic list instead of a fixed object you might find this link helpful.
Alternatively, you could save data to your application configuration file (search online for "C# application configuration for PROJECT_TYPE" where the project type is winforms/mvc/class library etc..)
When searching through files indexed using Windows Desktop Search,
it would be nice if I could see a snippet of the text within the
document that is related to the search text. However when I try to
retrieve "System.Search.QueryFocusedSummary" or
"System.Search.QueryFocusedSummaryWithFallback " I get a
"column name not found" error.
(The code that I am using to query this is shown in this question:
Microsoft Desktop Search - CONTAINS not returning results on windows server 2008 )
This is confusing because when you do a search within explorer,
you get the snippet of text in your results. So it's possible somehow.
According to this documentation http://msdn.microsoft.com/en-us/library/windows/desktop/bb760171%28v=vs.85%29.aspx
it should be retrievable, the same that AutoSummary is.
This question has already been asked on MSDN here:
http://social.msdn.microsoft.com/Forums/en-US/windowsdesktopsearchdevelopment/thread/dcfb40ea-b250-4294-80d0-727c7365745e/
but I'm hoping that the clever stackoverflow people can help me.
As a side note, I'm quite confused as to why this doesn't work, don't lots of
people need to index and search documents? Does everyone use Lucene and/or Solr
or Windows Search Server instead?
A colleague of mine ran into this problem recently. QueryFocusedSummary and QueryFocusedSummaryWithFallback are indeed not accessible via OLEDB. They are, however, accessible via Shell.
In the Windows SDK, there is a sample, $WIN_SDK/Samples/winui/shell/appplatform/ExplorerBrowserSearch, which will get you set up on using Shell functions to perform a search. From here, it should be trivial to add support for QueryFocusedSummary and QueryFocusedSummaryWithFallback via the Shell Property Keys PKEY_Search_QueryFocusedSummary and PKEY_Search_QueryFocusedSummaryWithFallback respectively.
Since you didn't post any code I have to speculate a bit...
I assume you are using OleDB/SQL to execute a query...
Neither QueryFocusedSummary nor QueryFocusedSummaryWithFallback are real columns and thus NOT available via OleDB/SQL !
The only columns available this way are AFAIK
AutoSummary
Contents
EntryID
GatherTime
Rank
Store
QueryFocusedSummary and QueryFocusedSummaryWithFallback are IIRC properties accessiable via COM or a Shell interface .
Requirement is that i want to identify that the text written in PDF or Doc is english or non english. if i got a single word of (turiskh, french,arabic and etc.) have to avoid the whole documnet
its urgent plz give me sample code for this functionality
Have a look on Google Translate API, only free service who could do this for you what I know. Otherwise I can only see the solution of having your own dictionary etc.. But thats a different story
I guess you could use LangId. However there are some restrictions:
To use our API in live websites or services we suggest you to apply for a free API key, using the below form. The API key expands your developing possibilities allowing you to do up till 1,000 requests per hour (~720,000 per month).
I don't think this will solve your 'single word' issue however. I believe if the text has 6 words English and 4 words in another language it will see the text as English since that language is mainly used in the file. I haven't looked at the API myself though so there might be some solutions for that.
Hope it is of use to you.
Maybe the detect function of Google's Translate API could help you:
http://code.google.com/apis/language/translate/v2/getting_started.html#language_detect
This is not possible for single words.
Is "the" an English word? Well, yes, but it's also a Danish word (meaning tea). Does the word Schadenfreude indicate a non-english text? Not necessarily, it all depends on the context.
Adding to the list of APIs that support language determination, Bing API has a call that will determine the language for an array of strings.

Hope this helps somewhat.
I was wondering if there is another way to spell check a Windows app instead what I've been of using: "Microsoft.Office.Interop.Word". I can't buy a spell checking add-on. I also cannot use open source and would like the spell check to be dynamic..any suggestions?
EDIT:
I have seen several similar questions, the problem is they all suggest using open source applications (which I would love) or Microsoft Word.
I am currently using Word to spell check and it slows my current application down and causes several glitches in my application. Word is not a clean solution so I'm really wanting to find some other way.. Is my only other option to recreate my app as a WPF app so I can take advantage of the SpellCheck Class?
If I were you I would download the data from the English Wiktionary and parse it to obtain a list of all English words (for instance). Then you could rather easily write at least a primitive spell-checker yourself. In fact, I use a parsed version of the English Wiktionary in my own mathematical application AlgoSim. If you'd like, I could send you the data file.
Update
I have now published a parsed word list at english.zip (942 kB, 383735 entries, zip). The data originates from the English Wiktionary, and as such, is licensed under the Creative Commons Attribution/Share-Alike License.
To obtain a list like this, you can either download all articles on Wiktionary as a huge XML file containing all Wiki- and HTML-formatted articles. This is then more or less trivial to parse. Alternatively, you can run a bot on the site. I got help to obtain a parsed file from a user at Wiktionary (I seem to have forgotten his name, though...), and this file (english.txt in english.zip) is a further processed version of the file I got.

I use Aspell-win32, it's old but it's open source, and works as well or better than the Word spell check. Came here looking for a built in solution.
I have a textbox and a button in one page.I want to enter a word in the textbox and click the button. After clicking the button I want to display the name of the web pages containing the word entered in the textbox. So please tell me how to do it? I am using C#.
So you want to create a search engine internal to your website. There are a couple of different options
You can use something like google custom search which requires no coding and uses the google technology which I think we all agree does a pretty good job compared to other search engines. More information at http://www.google.com/cse/
Or you can implement it in .net which I will try to give some pointers about below.
A search engine in general exists out of (some of) the following parts:
a index which is searched against
a query system which allows searches to be specified and results shown
a way to get documents into the index like a crawler or some event thats handled when the documents are created/published/updated.
These are non trivial things to create especially if you want a rich feature set like stemming (returning documents containing plural forms of search terms), highlighting results, indexing different document formats like pdf, rtf, html etc... so you want to use something already made for this purpose. This would only leave the task of connecting and orchestrating the different parts, writing the flow control logic.
You could use Lucene.net a opensource project with a lot of features. http://usoniandream.blogspot.com/2007/10/tutorial-implementing-lucenenet-search.html explains how to get started with it.
The other option is Microsoft indexing service which comes with windows but I would advice against it since it's difficult to tweak to work like you want and the results are sub-optimal in my opinion.
You are going to need some sort of backing store, and full text indexing. To the best of my knowledge, C# alone is not enough.
