  • [Java] Cannot find symbol

    - by m00st
    I've created a class called Entity this is the superclass. Actor has successfully extended Entity; now trying to do the same with Item results in the Cannot find symbol error. Here is example code: public class Actor extends Entity { Actor(String filename, int x, int y) { super(filename, x, y); } } works just fine but this doesn't: public class Item extends Entity { }

  • Returning a shared library symbol table

    - by joemoe
    For instance: void* sdl_library = dlopen("libSDL.so", RTLD_LAZY); void* initializer = dlsym(sdl_library,"SDL_Init"); Assuming no errors, initializer will point to the function SD_Init in the shared library libSDK.so. However this requires knowing the symbol "SDL_Init" exists. Is it possibly to query a library for all its symbols? Eg, in this case it would return SDL_Init, the function pointer, and any other symbols exported by libSDL.so.

  • undefined C/C++ symbol as operator

    - by uray
    I notice that the character/symbol '`' and '@' is not used as an operator in C/C++, does anyone know the reason or historically why its so? if its really not used, is it safe to define those symbols as another operator/statement using #define?

  • Lifting a math symbol in LaTeX

    - by Chris Conway
    I'm using the symbol \otimes as a unary operator and it's vertical alignment doesn't seem right to me. It wants to sit a bit below the baseline: and I tried using \raisebox to fix this, e.g., \raisebox{1pt}{$\otimes$}: But \raisebox doesn't seem to be sensitive to subscripts. The operator stays the same size while everything around it shrinks: The problem, I think, is that \raisebox creates its own LR box, which doesn't inherit the settings in the surrounding math environment. Is there a version of \raisebox that "respects math"?

  • Highlighting rows and columns in an HTML table using JQuery

    - by nikolaosk
    A friend of mine was seeking some help regarding HTML tables and JQuery. I have decided to write a few posts demonstrating the various techniques I used with JQuery to achieve the desired functionality. ?here are other posts in my blog regarding JQuery.You can find them all here.I have received some comments from visitors of this blog that are "complaining" about the length of the blog posts. I will not write lengthy posts anymore...I mean I will try not to do so..We will demonstrate this with a step by step example. I will use Visual Studio 2012 Ultimate. You can also use Visual Studio 2012 Express Edition. You can also use VS 2010 editions. 1) Launch Visual Studio. Create an ASP.Net Empty Web application. Choose an appropriate name for your application.2) Add a web form, default.aspx page to the application.3) Add a table from the HTML controls tab control (from the Toolbox) on the default.aspx page4) Now we need to download the JQuery library. Please visit the http://jquery.com/ and download the minified version.5) We will add a stylesheet to the application (Style.css)5) Obviously at some point we need to reference the JQuery library and the external stylesheet. In the head section ? add the following lines.   <link href="Style.css" rel="stylesheet" type="text/css" />       <script src="jquery-1_8_2_min.js" type="text/javascript"></script> 6) Now we need to highlight the rows when the user hovers over them.7) First we need to type the HTML markup<body>    <form id="form1" runat="server">    <div>        <h1>Liverpool Legends</h1>        <table style="width: 50%;" border="1" cellpadding="10" cellspacing ="10">            <thead>                <tr><th>Defenders</th><th>MidFielders</th><th>Strikers</th></tr>            </thead>            <tbody>            <tr>                <td>Alan Hansen</td>                <td>Graeme Souness</td>                <td>Ian Rush</td>            </tr>            <tr>                <td>Alan Kennedy</td>                <td>Steven Gerrard</td>                <td>Michael Owen</td>            </tr>            <tr>                <td>Jamie Garragher</td>                <td>Kenny Dalglish</td>                <td>Robbie Fowler</td>            </tr>            <tr>                <td>Rob Jones</td>                <td>Xabi Alonso</td>                <td>Dirk Kuyt</td>            </tr>                </tbody>        </table>            </div>    </form></body>8) Now we need to write the simple rules in the style.css file.body{background-color:#eaeaea;}.hover { background-color:#42709b; color:#ff6a00;} 8) Inside the head section we also write the simple JQuery code.  <script type="text/javascript"> $(document).ready(function() { $('tr').hover( function() { $(this).find('td').addClass('hover'); }, function() { $(this).find('td').removeClass('hover'); } ); }); </script>9) Run your application and see the row changing background color and text color every time the user hovers over it. Let me explain how this functionality is achieved.We have the .hover style rule in the style.css file that contains some properties that define the background color value and the color value when the mouse will be hovered on the row.In the JQuery code we do attach the hover() event to the tr elements.The function that is called when the hovering takes place, we search for the td element and through the addClass function we apply the styles defined in the .hover class rule in the style.css file.I remove the .hover rule styles with the removeClass function. Now let's say that we want to highlight only alternate rows of the table.We need to add another rule in the style.css.alternate { background-color:#42709b; color:#ff6a00;} The JQuery code (comment out the previous JQuery code) follows  <script type="text/javascript">        $(document).ready(function() {                     $('table tr:odd').addClass('alternate');        });    </script>  When I run my application through VS I see the following result You can do that with columns as well. You can highlight alternate columns as well.The JQuery code (comment out the previous JQuery code) follows  <script type="text/javascript">        $(document).ready(function() {                      $('td:nth-child(odd)').addClass('alternate');        });    </script>  In this script I use the nth-child() method in the JQuery code.This method retrieves all the elements that are nth children of their parent.Have a look at the picture below to see the resultsYou can also change color to each individual cell when hovered on.The JQuery code (comment out the previous JQuery code) follows    <script type="text/javascript">        $(document).ready(function() {          $('td').hover(                  function() {                 $(this).addClass('hover');               },                function() {                    $(this).removeClass('hover');                }                );        });    </script> Have a look at the picture below to see the results. Hope it helps!!!

  • How to use symbols/punctuation characters in discriminated unions

    - by user343550
    I'm trying to create a discriminated union for part of speech tags and other labels returned by a natural language parser. It's common to use either strings or enums for these in C#/Java, but discriminated unions seem more appropriate in F# because these are distinct, read-only values. In the language reference, I found that this symbol ``...`` can be used to delimit keywords/reserved words. This works for type ArgumentType = | A0 // subject | A1 // indirect object | A2 // direct object | A3 // | A4 // | A5 // | AA // | ``AM-ADV`` However, the tags contain symbols like $, e.g. type PosTag = | CC // Coordinating conjunction | CD // Cardinal Number | DT // Determiner | EX // Existential there | FW // Foreign Word | IN // Preposision or subordinating conjunction | JJ // Adjective | JJR // Adjective, comparative | JJS // Adjective, superlative | LS // List Item Marker | MD // Modal | NN // Noun, singular or mass | NNP // Proper Noun, singular | NNPS // Proper Noun, plural | NNS // Noun, plural | PDT // Predeterminer | POS // Possessive Ending | PRP // Personal Pronoun | PRP$ //$ Possessive Pronoun | RB // Adverb | RBR // Adverb, comparative | RBS // Adverb, superlative | RP // Particle | SYM // Symbol | TO // to | UH // Interjection | VB // Verb, base form | VBD // Verb, past tense | VBG // Verb, gerund or persent participle | VBN // Verb, past participle | VBP // Verb, non-3rd person singular present | VBZ // Verb, 3rd person singular present | WDT // Wh-determiner | WP // Wh-pronoun | WP$ //$ Possessive wh-pronoun | WRB // Wh-adverb | ``#`` | ``$`` | ``''`` | ``(`` | ``)`` | ``,`` | ``.`` | ``:`` | `` //not sure how to escape/delimit this ``...`` isn't working for WP$ or symbols like ( Also, I have the interesting problem that the parser returns `` as a meaningful symbol, so I need to escape it as well. Is there some other way to do this, or is this just not possible with a discriminated union? Right now I'm getting errors like Invalid namespace, module, type or union case name Discriminated union cases and exception labels must be uppercase identifiers I suppose I could somehow override toString for these goofy cases and replace the symbols with some alphanumeric equivalent?

  • Xcode duplicate symbol _main .

    - by Prithvi Raj
    I'm getting the following error in Xcode 3.2.1 on Snow Leopard 10.6.2 whenever I try to compile any iPhone application generated by Appcelerator's Titanium . However , the build error only appears when I select iPhone simulator on the architecture menu , and if I select iPhone device , I am able to run the app on my device . Further , the iPhone simulator launches successfully and executes the program directly from the Titanium environment , which uses Xcode to build . Why is this happening ? ld: duplicate symbol _main in Resources/libTitanium.a(main.o) and /Users/prithviraj/Documents/project/Final/build/iphone/build/Final.build/Debug-iphonesimulator/Final.build/Objects-normal/i386/main.o collect2: ld returned 1 exit status Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

  • LINKED TABLES BETWEEN MS ACCESS 2003 AND MS ACCESS 2007-WRITE PERMISSIONS DENIED

    - by STEVE KING
    We are in the process of switching over to ACCESS 2007. We have numerous data tables in ACCESS 2003 files. In one case, the user has 2007 on his PC and opend the front end in 2007. No problems. When the the user is done, he clicks a button that executes a macro full of update queries. The macro reaches the first query and halts. We get a messge saying we do not have permisons to write to this linked table (2003 format). There were no security files involved. We re-linked from 2007, same problem. LAN permssions were ok. I wound up having to import the tables to front end in order for the user to be able to do his job.
