• Preview Before You Paste with Live Preview in Office 2010

  - by DigitalGeekery

  Do you often find yourself frustrated that content you just copied and pasted didn’t turn out the way you expected? With the new Live Preview in Office 2010, you can preview how copied content will look when it’s pasted even between Office applications. Not every paste preview option will be available in every circumstance. The available options will be based on the applications being used and what content is copied. Copy your content like normal by right-clicking and selecting Copy, pressing Crtl + C, or selecting Copy from the Home tab. Next, select your location to paste the content. Now you can access the Paste Preview buttons either by selecting the Paste dropdown list from the Home tab…   …Or by right-clicking. As you hover your cursor over each of the Paste Options buttons, you will see a preview of what it will look like if you paste using that option. Click the corresponding button when you find the paste option you like. The “Paste” will paste all the content and formatting as you can see below. Values will paste values only, no formatting.   Formatting will paste only the formatting, no values. Hover over Paste Special to reveal any additional paste options. The process is similar in other Office applications. As you can see in the Word document below, Keep Text Only will paste the text, but not the orange color format from the original text.   Even after you’ve pasted, there is still time to change your mind. After you paste content you’ll see a Paste Option button near your content. If you don’t, you can pull it up by pressing the Ctrl key. Note: This is also available after using Ctrl + V to paste. Click to enable the dropdown and select one of the available options.   Using Live Paste Preview between multiple applications is just as easy. If we preview pasting the content from our Word document into PowerPoint by using the Keep Source Formatting option, we’ll see that the outcome looks awful. Selecting the Use Destination Theme will merge the text into the theme of the PowerPoint document and looks a lot better on our slide.   Live Paste Preview is a nice addition to Office 2010 and is sure to save time spent undoing the unexpected consequences of pasting content.

• Access Control Service: Protocol and Token Transition

  - by Your DisplayName here!

  ACS v2 supports a number of protocols (WS-Federation, WS-Trust, OpenId, OAuth 2 / WRAP) and a number of token types (SWT, SAML 1.1/2.0) – see Vittorio’s Infographic here. Some protocols are designed for active client (WS-Trust, OAuth / WRAP) and some are designed for passive clients (WS-Federation, OpenID). One of the most obvious advantages of ACS is that it allows to transition between various protocols and token types. Once example would be using WS-Federation/SAML between your application and ACS to sign in with a Google account. Google is using OpenId and non-SAML tokens, but ACS transitions into WS-Federation and sends back a SAML token. This way you application only needs to understand a single protocol whereas ACS acts as a protocol bridge (see my ACS2 sample here). Another example would be transformation of a SAML token to a SWT. This is achieved by using the WRAP endpoint – you send a SAML token (from a registered identity provider) to ACS, and ACS turns it into a SWT token for the requested relying party, e.g. (using the WrapClient from Thinktecture.IdentityModel): [TestMethod] public void GetClaimsSamlToSwt() {     // get saml token from idp     var samlToken = Helper.GetSamlIdentityTokenForAcs();     // send to ACS for SWT converion     var swtToken = Helper.GetSimpleWebToken(samlToken);     var client = new HttpClient(Constants.BaseUri);     client.SetAccessToken(swtToken, WebClientTokenSchemes.OAuth);     // call REST service with SWT     var response = client.Get("wcf/client");     Assert.AreEqual<HttpStatusCode>(HttpStatusCode.OK, response.StatusCode); } There are more protocol transitions possible – but they are not so obvious. A popular example would be how to call a REST/SOAP service using e.g. a LiveId login. In the next post I will show you how to approach that scenario.

• SEO non-English domain name advice

  - by Dominykas Mostauskis

  I'm starting a website, that is meant for a non-English region, using an alphabet that is a bit different than that of English. Current plan is as follows. The website name, and the domain name, will be in the local language (not English); however, domain name will be spelled in the English alphabet, while the website's title will be the same word(s), but spelled properly with accents. E.g.: 'www.litterat.fr' and 'Littérat'. Does the difference between domain name and website name character use influence the site's SEO? Is it better, SEO-wise, to choose a name that can be spelled the same way in the English alphabet? From my experience, when searching online, invariably, the English alphabet is used, no matter the language, so people will still be searching 'litterat' (without accents and such). Edit: To sum up: Things have been said about IDN (Internationalized domain name). To make it simple, they are second-level domain names that contain language specific characters (LSP)(e.g. www.café.fr). Here you can check what top-level domains support what LSPs. Check initall's answer for more info on using LSPs in paths and queries. To answer my question about how and if search engines relate keywords spelled with and without language specific characters: Google can potentially tell that series and séries is the same keyword. However, (most relevant for words that are spelled differently across languages and have different meanings, like séries), for Google to make the connection (or lack thereof) between e and é, it has to deduce two things: Language that you are searching in. Language of your query. You can specify it manually through Advanced search or it guesses it, sometimes. I presume it can guess it wrong too. The more keywords specific to this language you use the higher Google's chance to guess the language. Language of the crawled document, against which the ASCII version of the word will be compared (in this example – series). Again, check initall's answer for how to help Google in understanding what language your document is in. Once it has that it can tell whether or not these two spellings should be treated as the same keyword. Google has to understand that even though you're not using french (in this example) specific characters, you're searching in French. The reason why I used the french word séries in this example, is that it demonstrates this very well. You have it in French and you have it in English without the accent. So if your search query is ambiguous like our series, unless Google has something more to go on, it will presume that there's no correlation between your search and séries in French documents. If you augment your query to series romantiques (try it), Google will understand that you're searching in French and among your results you'll see séries as well. But this does not always work, you should test it out with your keywords first. For example, if you search series francaises, it will associate francaises with françaises, but it will not associate series with séries. It depends on the words. Note: worth stressing that this problem is very relevant to words that, written in plain ASCII, might have some other meanings in other languages, it is less relevant to words that can be, by a distinct margin, just some one language. Tip: I've noticed that sometimes even if my non-accented search query doesn't get associated with the properly spelled word in a document (especially if it's the title or an important keyword in the doc), it still comes up. I followed the link, did a Ctrl-F search for my non-accented search query and found nothing, then checked the meta-tags in the source and you had the page's title in both accented and non-accented forms. So if you have meta-tags that can be spelled with language specific characters and without, put in both. Footnote: I hope this helps. If you have anything to add or correct, go ahead.

• Is there a variable width font that does not change width when adding effects like bold, italic?

  - by George Bailey

  NetBeans has a word wrap feature now - but if the font changes width when bold then it gets all jumpy and sometimes hard to work with. Edit: It turns out that even with Courier New that NetBeans word wrap still jumps up and down lines at a time at random. I guess that this question no longer cares for an answer. However,, it seems that there is no answer. (at least nobody has brought one up yet) I am currently using Comic Sans MS which gets wider when bold.

• Favorite Visual Studio 2010 Extensions

  - by Scott Dorman

  Now that Visual Studio 2010 has been released, there are a lot of extensions being written. In fact, as of today (May 1, 2010 at 15:40 UTC) there are 809 results for Visual Studio 2010 in the Visual Studio Gallery. If you filter this list to show just the free items, there are still 251 extensions available. Given that number (and it is currently increasing weekly) it can be difficult to find extensions that are useful.

• Can the overuse of custom taglibs disrupt the outsourcing of html designers?

  - by Renato Gama

  Yesterday me and a friend were talking about the overuse of custom taglibs! We create taglibs for everything! We create taglibs in order to wrap jQuery UI elements (tabs, button, etc), and other plugins elements as well. We often wrap them together in a single component. We use taglibs in a point that we almost have no pure html within the body tag. Our question is: is this a healthy habit??? Imagine two situations: 1) We hire an html designer and have the cost of a month for him to learn all this stuff. 2) We want to outsource the html development but no company would get our taglib library to learn, OR it become more expensive. We love taglibs as its been a lovely shortcut for javascipt development as we write it only once. What would be the best practices in this sense, and what would you suggest? We are looking for a future-proof solution (or an argument that agrees with ours).

• Long lines of text in source code [closed]

  - by ale

  Possible Duplicate: Is the 80 character limit still relevant in times of widescreen monitors? I used to set a vertical line set at 80 characters in my text editor and then I added carriage returns if the lines got too long. I later increased the value to 135 characters. I started using word wrap and not giving myself a limit but tried to keep lines short if I could because it took a lot of time shortening my lines. People at work use word wrap and don't give themselves a limit.. is this the correct way? What are you meant to do ? Many thanks.

  How to do to avoid having the scroller with a sticky footer to the bottom of the page (not bottom of window)? When I remove height=100% from content and sidebar, I'm no more getting the scroller. However, when doing so, my content and sidebar do not fill all the space down to the footer. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Untitled 13</title> <style media="all" type="text/css"> * { margin: 0; padding: 0; } html, body, #wrap, form { height: 100%; } #wrap, #footer { width: 750px; margin: 0 auto; } #wrap { background: #cff; } html, body { color: #000; background: #a7a09a; } body > #wrap { height: 100%; min-height: 100%; } form { /*height: auto;*/ min-height: 100%; } #main { background: #000; height:100%; min-height:100%; height: auto !important; */ } #content { height:100%; float: left; padding: 10px; float: left; width: 570px; background: #9c9; } #sidebar { height:100%; float: left; width: 140px; background: #c99; padding: 10px; } #footer { position: relative; margin-top: -100px; height: 100px; clear: both; background: #cc9; bottom: 0; } .clearfix:after { content: "."; display: block; height: 0; clear: both; visibility: hidden; } .clearfix { display: inline-block; } * html .clearfix { height: 1%; } .clearfix { display: block; } #header { /*padding: 5px 10px;*/ background: #ddd; } </style> </head> <body> <form id="form1" runat="server"> <div id="wrap"> <div id="main" class="clearfix"> <div id="header"> <h1>header</h1> </div> <div id="sidebar"> <h2>sidebar</h2> </div> <div id="content"> <h2>main content</h2> </div> </div> </div> <div id="footer"> <h2>footer</h2> </div> </form> </body> </html>

• jQuery bug when trying to insert partial elements before() / after() ?

  - by RedGlobe

  I'm trying to wrap a div around an element (my 'template' div) by using jQuery's before() and after(). When I try to insert a closing after the selected element, it actually gets placed before the target. Example: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <title>Div Wrap</title> <script src="http://code.jquery.com/jquery-1.4.4.min.js"></script> <script> $('document').ready(function() { var beforestr = "<div id=\"wrap\"><div id=\"header\">Top</div><div id=\"page\">"; var afterstr = "</div><div id=\"footer\">Bottom</div></div>"; $('#template').before(beforestr); $('#template').after(afterstr); }); </script> </head> <body> <div id="template"> <h1>Page Title</h1> <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Mauris placerat eleifend leo. Quisque sit amet est et sapien ullamcorper pharetra. <script>document.write('This script should still work and might contain variables. Please don\'t recommend concatenation.');</script> Donec non enim in turpis pulvinar facilisis.</p> </div> </body> </html> The result is: <div id="wrap"> <div id="header">Top</div> <div id="page"> </div> </div> <div id="template"> <h1>Page Title</h1> <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Mauris placerat eleifend leo. Quisque sit amet est et sapien ullamcorper pharetra. This script should still work and might contain variables. Please don't recommend concatenation. Donec non enim in turpis pulvinar facilisis.</p> </div> <div id="footer">Bottom</div> Why are my closing wrap and page divs getting placed before the target, when I'm trying to place them after() ? Is there an alternative way to accomplish this (keeping in mind I may need to call script functions within the template div)? As I'm sure you're aware, best practices aren't what I'm going for here.

• Convert CRC-CCITT Kermit 16 DELPHI code to C#

  - by Mehdi Anis

  I am working on a function that will give me a Kermit CRC value from a HEX string. I have a piece of code in DELPHI. I am a .NET developer and need the code in C#. function CRC_16(cadena : string):word; var valuehex : word; i: integer; CRC : word; Begin CRC := 0; for i := 1 to length(cadena) do begin valuehex := ((ord(cadena[i]) XOR CRC) AND $0F) * $1081; CRC := CRC SHR 4; CRC := CRC XOR valuehex; valuehex := (((ord(cadena[i]) SHR 4) XOR LO(CRC)) AND $0F); CRC := CRC SHR 4; CRC := CRC XOR (valuehex * $1081); end; CRC_16 := (LO(CRC) SHL 8) OR HI(CRC); end; I got the code from this webpage: Kermit CRC in DELPHI I guess that Delphi function is correct. If any one can please convert the code to C# that will be great. I tried to convert to C#, but got lost in WORD data type and the LO function of Delphi. Thank you all.

• How do I get 3 lines of text from a paragraph

  - by Keltex

  I'm trying to create an "snippet" from a paragraph. I have a long paragraph of text with a word hilighted in the middle. I want to get the line containing the word before that line and the line after that line. I have the following piece of information: The text (in a string) The lines are deliminated by a NEWLINE character \n I have the index into the string of the text I want to hilight A couple other criteria: If my word falls on first line of the paragraph, it should show the 1st 3 lines If my word falls on the last line of the paragraph, it should show the last 3 lines Should show the entire paragraph in the degenative cases (the paragraph only has 1 or 2 lines) Here's an example: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph Example, if my index points to BIRD, it should show lines 1, 2, & 3 as one complete string like this: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph If my index points to DOG, it should show lines 3, 4, & 5 as one complete string like this: This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph etc. Anybody want to help tackle this?

• onComplete for Ajax.Request sometimes does not hide the load animation in Prototype

  - by TenJack

  I have a Ajax.Request in which I use onLoading and onComplete to show and hide a load animation gif. The problem is that every 10 clicks or so, the load animation fails to hide and just stays there animating even though the ajax request has returned successfully. I have a number of div elements that each has its own respective load animation and an onclick with the Ajax.Request that looks like this: <div id="word_block_<%= word_obj.word %>" class="word_block" > <%= image_tag("ajax-loader_word_block.gif", :id => "load_animation_#{word_obj.word}", :style => 'display:none') %> <a href="#" onclick="new Ajax.Request('/test/ajax_load', {asynchronous:true, evalScripts:true, onLoading:function() { Element.show('load_animation_<%= word_obj.word %>')}, onComplete:function(){ Element.hide('load_animation_<%= word_obj.word %>')}}); return false;">Click Here</a> </div> Does it look like anything could be wrong with this? Maybe I should try removing the inline onclick and add an onclick programmatically with javascript? I really have no idea why this keeps happening. I am using the prototype library with ruby on rails.

• Improve Efficiency for This Text Processing Code

  - by johnv

  I am writing a program that counts the number of words in a text file which is already in lowercase and separated by spaces. I want to use a dictionary and only count the word IF it's within the dictionary. The problem is the dictionary is quite large (~100,000 words) and each text document has also ~50,000 words. As such, the codes that I wrote below gets very slow (takes about 15 sec to process one document on a quad i7 machine). I'm wondering if there's something wrong with my coding and if the efficiency of the program can be improved. Thanks so much for your help. Code below: public static string WordCount(string countInput) { string[] keywords = ReadDic(); /* read dictionary txt file*/ /*then reads the main text file*/ Dictionary<string, int> dict = ReadFile(countInput).Split(' ') .Select(c => c) .Where(c => keywords.Contains(c)) .GroupBy(c => c) .Select(g => new { word = g.Key, count = g.Count() }) .OrderBy(g => g.word) .ToDictionary(d => d.word, d => d.count); int s = dict.Sum(e => e.Value); string k = s.ToString(); return k; }

• Selectively replacing words outside of tags using regular expressions in PHP?

  - by Gary Willoughby

  I have a paragraph of text and i want to replace some words using PHP (preg_replace). Here's a sample piece of text: This lesson addresses rhyming [one]words and ways[/one] that students may learn to identify these words. Topics include learning that rhyming words sound alike and these sounds all come from the [two]ending of the words[/two]. This can be accomplished by having students repeat sets of rhyming words so that they can say them and hear them. The students will also participate in a variety of rhyming word activities. In order to demonstrate mastery the students will listen to [three]sets of words[/three] and tell the teacher if the words rhyme or not. If you notice there are many occurances of the word 'words'. I want to replace all the occurances that don't occur inside any of the tags with the word 'birds'. So it looks like this: This lesson addresses rhyming [one]words and ways[/one] that students may learn to identify these birds. Topics include learning that rhyming birds sound alike and these sounds all come from the [two]ending of the words[/two]. This can be accomplished by having students repeat sets of rhyming birds so that they can say them and hear them. The students will also participate in a variety of rhyming word activities. In order to demonstrate mastery the students will listen to [three]sets of words[/three] and tell the teacher if the birds rhyme or not. Would you use regular expressions to accomplish this? Can a regular expression accomplish this?

• Office Automation: What does destroy my encoding?

  - by Filburt

  I'm facing a problem with a Word Mail Merge Automation controlled by our CRM system. The setup Base for the Mail Merge is a Word .dot template which fires a macro on Document.New. Inside this macro I create a .Net component registered for COM. Set myCOMObject = CreateObject("MyCOMObject") The component pulls some data from a database and hands string values which are assigned to Word DocumentVariables. Set someClass = myCOMObject.GetSomeClass(123) ActiveDocument.Variables("docaddress") = someClass.GetSenderAddress(456) All string values returned from the component are encoded in UTF-8 (codepage 1200). What happens The problem arises when the CRM system calls Word to perform the Mail Merge: The string values from the component are turned into UTF-8 encoded strings. All the static text inside the template and the data pulled for the Mail Merge stay nicely encoded in UTF-16 - example the umlaut ü inside my DocumentVariables is turned into c3 b0 while it stays fc for the rest of the document (checked file in hex editor). If I'm creating a document from a template with the same macro functionallity but without performing a Mail Merge all strings are fine; i.e. are encoded in UTF-16. What changed According to the CRM software vendor the encoding of the Mail Merge data export was changed to UTF-16 with the new version we're currently testing. I found out that MS states that you'll expirience issues when the document and the Mail Merge data file encoding don't match. What I tried Since I'm assuming to merge with UTF-16 encoded data I added the following lines to my macro: ActiveDocument.TextEncoding = msoEncodingWestern ActiveDocument.SaveEncoding = msoEncodingUnicodeLittleEndian This is what the Mail Merge data document specifies in its document properties.

• SQL with Regular Expressions vs Indexes with Logical Merging Functions

  - by geeko

  Hello Lads, I am trying to develop a complex textual search engine. I have thousands of textual pages from many books. I need to search pages that contain specified complex logical criterias. These criterias can contain virtually any compination of the following: A: Full words. B: Word roots (semilar to stems; i.e. all words with certain key letters). C: Word templates (in some languages are filled in certain templates to form various part of speech such as adjactives, past/present verbs...). D: Logical connectives: AND/OR/XOR/NOT/IF/IFF and parentheses to state priorities. Now, would it be faster to have the pages' full text in database (not indexed) and search though them all using SQL and Regular Expressions ? Or would it be better to construct indexes of word/root/template-page-location tuples. Hence, we can boost searching for individual words/roots/templates. However, it gets tricky as we interdouce logical connectives into our query. I thought of doing the following steps in such cases: 1: Seperately search for each individual words/roots/templates in the specified query. 2: On priority bases, we merge two result lists (from step 1) at a time depedning on the logical connective For example, if we are searching for "he AND (is OR was)": 1: We shall search for "he", "is" and "was" seperately and get result lists for each word. 2: Merge the result lists of "is" and "was" using the merging function OR-MERGE 3: Merge the merged result list from the OR-MERGE function with the one of "he" using the merging function AND-MERGE The result of step 3 is then returned as the result of the specified query. What do you think gurues ? Which is faster ? Any better ideas ? Thank you all in advance.

• How to make a small engine like Wolfram|Alpha?

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  Lets say I have three models/tables: operating_systems, words, and programming_languages: # operating_systems name:string created_by:string family:string Windows Microsoft MS-DOS Mac OS X Apple UNIX Linux Linus Torvalds UNIX UNIX AT&T UNIX # words word:string defenitions:string window (serialized hash of defenitions) hello (serialized hash of defenitions) UNIX (serialized hash of defenitions) # programming_languages name:string created_by:string example_code:text C++ Bjarne Stroustrup #include <iostream> etc... HelloWorld Jeff Skeet h AnotherOne Jon Atwood imports 'SORULEZ.cs' etc... When a user searches hello, the system shows the defenitions of 'hello'. This is relatively easy to implement. However, when a user searches UNIX, the engine must choose: word or operating_system. Also, when a user searches windows (small letter 'w'), the engine chooses word, but should also show Assuming 'windows' is a word. Use as an <a href="etc..">operating system</a> instead. Can anyone point me in the right direction with parsing and choosing the topic of the search query? Thanks. Note: it doesn't need to be able to perform calculations as WA can do.

Exception 'illegal type' from interface apparently because values being constants(?!) static interface userInfo { File startingFile=new File("."); String startingPath="dummy"; try{ startingPath=startingFile.getCanonicalPath(); }catch(Exception e){e.printStackTrace();} } Working code but no succes with non-static inner class import java.io.*; import java.util.*; public class listTest{ public interface hello{String word="hello word from Interface!";} public static class hej{ hej(){} private String hejo="hello hallo from Static class with image"; public void printHallooo(){System.out.println(hejo);} } public class nonStatic{ nonStatic(){} //HOW TO USE IT? public void printNonStatic(){System.out.println("Inside static class with an image!");} } public static void main(String[] args){ //INTERFACE TEST System.out.println(hello.word); //INNNER CLASS STATIC TEST hej h=new hej(); h.printHallooo(); //INNER CLASS NON-STATIC TEST nonStatic ns=new nonStatic(); ns.printNonStatic(); //IS there a way to it without STATIC? } } Output The above code works but how non-staticly? Output: hello word from Interface! hello hallo from Static class with image! StaticPrint without an image of the class! Related Nesting classes inner classes? interfacses

• How do I get 3 lines of text from a paragraph in C#

  - by Keltex

  I'm trying to create an "snippet" from a paragraph. I have a long paragraph of text with a word hilighted in the middle. I want to get the line containing the word before that line and the line after that line. I have the following piece of information: The text (in a string) The lines are deliminated by a NEWLINE character \n I have the index into the string of the text I want to hilight A couple other criteria: If my word falls on first line of the paragraph, it should show the 1st 3 lines If my word falls on the last line of the paragraph, it should show the last 3 lines Should show the entire paragraph in the degenative cases (the paragraph only has 1 or 2 lines) Here's an example: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph Example, if my index points to BIRD, it should show lines 1, 2, & 3 as one complete string like this: This is the 1st line of CAT text in the paragraph This is the 2nd line of BIRD text in the paragraph This is the 3rd line of MOUSE text in the paragraph If my index points to DOG, it should show lines 3, 4, & 5 as one complete string like this: This is the 3rd line of MOUSE text in the paragraph This is the 4th line of DOG text in the paragraph This is the 5th line of RABBIT text in the paragraph etc. Anybody want to help tackle this?

• Finding specific words in a file (Python language)

  - by Caroline Yi

  I have to write a program in python where the user is given a menu with four different "word games". There is a file called dictionary.txt and one of the games requires the user to input a) the number of letters in a word and b) a letter to exclude from the words being searched in the dictionary (dictionary.txt has the whole dictionary). Then the program prints the words that follow the user's requirements. My question is how on earth do I open the file and search for words with a certain length in that file. I only have a basic code which only asks the user for inputs. I'm am very new at this please help :( this is what I have up to the first option. The others are fine and I know how to break the loop but this specific one is really giving me trouble. I have tried everything and I just keep getting errors. Honestly, I only took this class because someone said it would be fun. It is, but recently I've really been falling behind and I have no idea what to do now. This is an intro level course so please be nice I've never done this before until now :( print print "Choose Which Game You Want to Play" print "a) Find words with only one vowel and excluding a specific letter." print "b) Find words containing all but one of a set of letters." print "c) Find words containing a specific character string." print "d) Find words containing state abbreviations." print "e) Find US state capitals that start with months." print "q) Quit." print choice = raw_input("Enter a choice: ") choice = choice.lower() print choice while choice != "q": if choice == "a": #wordlen = word length user is looking for.s wordlen = raw_input("Please enter the word length you are looking for: ") wordlen = int(wordlen) print wordlen #letterex = letter user wishes to exclude. letterex = raw_input("Please enter the letter you'd like to exclude: ") letterex = letterex.lower() print letterex

• a question related to URL

  - by Robert

  Dear all,Now i have this question in my java program,I think it should be classified as URL problem,but not 100% sure.If you think I am wrong,feel free to recategorize this problem,thanks. I would state my problem as simply as possible. I did a search on the famouse Chinese search engine baidu.com for a Chinese key word "???" (Obama in English),and the way I do that is to pass a URL (in a Java Program)to the browser like: http://news.baidu.com/ns?word=??? and it works perfectly just like I input the "???”keyword in the text field on baidu.com. However,now my advisor wants another thing.Since he can not read the Chinese webpages,but he wants to make sure the webpages I got from Baidu.com is related to "Obama",he asked me to google translate it back,i.e,using google translate and translate the Chinese webpage to English one. This sounds straightforward.However,I met my problem here. If I simply pass the URL "http://news.baidu.com/ns?word=???" into Google Translate and tick "Chinese to English" translating option,the result looks awful.(I don't know the clue here,maybe related to Chinese character encoding). Alternatively,if now my browser opens ""http://news.baidu.com/ns?word=???" webpage,but I click on the "????" button (that simply means "search"),you will notice the URL will get changed,now if I pass this URL into the Google translate and do the same thing,the result works much better. I hope I am not making this problem sound too complicated,and I appologize for some Chinese words invovled,but I really need your guys' help here.Becasue I did all this in a Java program,I couldn't figure out how to realize that "????"(pressing search button) step then get the new URL.If I could get that new URL,things are easy,I could just call Google translate in my Java code,and pops out the new window to show my advisor. Please share any of your idea or thougts here.Thanks a lot. Robert

• Deleting a node from linked list in C

  - by LuckySlevin

  My problem is deleting a node from linked list. I have two structs : typedef struct inner_list { int count; char word[100]; inner_list*next; } inner_list; typedef struct outer_list { char word [100]; inner_list * head; int count; outer_list * next; } outer_list; My problem is in deleting a node from outer_list linked list. For example when user entered aaa to delete, delete function should find the node with outer_list->word = aaa and delete this node and reconnect the list again. I tried the below code to do this. but After finding and deleting I'm losing the list. I don't know what's wrong. Please notice that outer_list have also a linked list of inner_list inside. void delnode(outer_list *head,char num[100]) { outer_list *temp, *m; temp=head; while(temp!=NULL) { if(strcmp(temp->word==num)==0) { if(temp==head) { head=temp->next; free(temp); return; } else { m->next=temp->next; free(temp); return; } }else { m=temp; temp= temp->next; } } printf(" ELEMENT %s NOT FOUND ", num); } What are your ideas about this?

• Full Text Search like Google

  - by Eduardo

  I would like to implement full-text-search in my off-line (android) application to search the user generated list of notes. I would like it to behave just like Google (since most people are already used to querying to Google) My initial requirements are: Fast: like Google or as fast as possible, having 100000 documents with 200 hundred words each. Searching for two words should only return documents that contain both words (not just one word) (unless the OR operator is used) Case insensitive (aka: normalization): If I have the word 'Hello' and I search for 'hello' it should match. Diacritical mark insensitive: If I have the word 'así' a search for 'asi' should match. In Spanish, many people, incorrectly, either do not put diacritical marks or fail in correctly putting them. Stop word elimination: To not have a huge index meaningless words like 'and', 'the' or 'for' should not be indexed at all. Dictionary substitution (aka: stem words): Similar words should be indexed as one. For example, instances of 'hungrily' and 'hungry' should be replaced with 'hunger'. Phrase search: If I have the text 'Hello world!' a search of '"world hello"' should not match it but a search of '"hello world"' should match. Search all fields (in multifield documents) if no field specified (not just a default field) Auto-completion in search results while typing to give popular searches. (just like Google Suggest) How may I configure a full-text-search engine to behave as much as possible as Google? (I am mostly interested in Open Source, Java and in particular Lucene)
