  • How do you implement syntax highlighting?

    - by ML
    I am embarking on some learning and I want to write my own syntax highlighting for files in C++. Can anyone give me ideas on how to go about doing this? To me it seems that when a file is opened: It would need to be parsed and decided what type of source file it is. Trusting the extension might not be fool-proof A way to know what keywords/commands apply to what language A way to decide what color each keyword/command gets I want to do this on OS X, using C++ or Objective-C. Can anyone provide pointers on how I might get started with this?

    - by Vinay Pandey
    Hi All, I know its silly question but I am struggling in allowing japanese/other such languages search for my web application using lucene.net. I know that different analyzers can be used for all different languages and can be implemented but I could not find any dll for analyzers or example for the same. the question is:- Will using different analyzers be a good option for web application, as search text can be in any form. Where can I find dll and sample application for implementing search for all different sets of language I have spend whole day but no luck :(.

  • The most elegant way to encapsulate WinAPI callbacks inside a class

    - by FractalizeR
    Hello. I am thinking about elegant way to encapsulate WinAPI callbacks inside a class. Suppose I am making a class handling asynchronous I/O. All Windows callbacks should be stdcall functions, not class methods (I need to pass their addresses to ReadFileEx WinAPI function for example). So, I cannot just pass method addresses as a callback routines to WinAPI functions. What is the most elegant way to encapsulate functionality of this type inside a class so that the class have events OnReadCompleted and OnWriteCompleted (I am using Delphi as a primary language, but I guess the situation must be the same in C++ because class methods are different from simple methods by the fact, that the first hidden parameter of them is this link. Of course this class is not a singleton and there can be many of them created by app at the same time. What do you think would be the good way to implement this?

  • wanting to move up from ms access, thinking .net? visual studio?

    - by Tristan Lear
    So I wrote a project-management program for a small business using Microsoft Access 2007. Now they've requested lots of additional features (timekeeping, privileged data tiers ...) I personally use Linux, but the whole office uses Windows. I'm relatively new to programming but like to teach myself using projects like this. I'm right on the edge on this -- I can't really tell what the path of least resistance here is: do I stay in access + VBA and teach myself a dying, annoying language -- while struggling against all the limitations of Access? Or do I move to something else? Python seems simple enough ... Whatever I use, i need to be able to offer a GUI.

  • jquery, moving the current item to the top

    - by azz0r
    Hello, The problem I'm having is that if the fourth item has a long description, it cuts off as it goes below #features. What I was hoping is someone would have a suggestion on how to make the current item selected to move to the top? Code below: <!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> <script type="text/javascript" src="/library/jquery/1.4.js"></script> <script> Model.FeatureBar = { current:0, items:{}, init: function init(options){ var me = this; me.triggers = [] me.slides = [] this.container = jQuery('#features'); jQuery('.feature').each(function(i){ me.triggers[i] = {url: jQuery(this).children('.feature-title a').href, title: jQuery(this).children('.feature-title'),description:jQuery(this).children('.feature-description')} me.slides[i] = {image: jQuery(this).children('.feature-image')} }); for(var i in this.slides){ this.slides[i].image.hide(); this.triggers[i].description.hide(); } Model.FeatureBar.goToItem(0); setInterval(function(){Model.FeatureBar.next()},5000); }, next: function next(){ var i = (this.current+1 < this.triggers.length) ? this.current+1 : 0; this.goToItem(i); }, previous: function previous(){ var i = (this.current-1 > 1) ? this.current-1 : this.triggers.length; this.goToItem(i); }, goToItem: function goToItem(i) { if (!this.slides[i]) { throw 'Slide out of range'; } this.triggers[this.current].description.slideUp(); this.triggers[i].description.slideDown(); this.slides[this.current].image.hide(); this.slides[i].image.show(); this.current = i; }, } </script> </head> <body> <div id="features"> <div class="feature current"> <div style="display: none;" class="feature-image"> <a href="google.com"><img src="/design/images/four-oh-four.png"></a> </div> <h2 class="feature-title"><a href="google.com">Item 3</a></h2> <p style="display: none;" class="feature-description"><a href="google.com">Item 3 description</a></p> </div> <div class="feature"> <div class="movie-cover"> <a href="/movie/movie"><img src="/image1" alt="" title=""></a> </div> <div style="display: block;" class="feature-image"> <a href="/rudeboiz-14-arse-splitters/movie"><img src="/images/Featured/rude.png"></a> </div> <h2 class="feature-title"><a href="/rude/movie">Item 2</a></h2> <p style="display: block;" class="feature-description"><a href="/rude/movie">Item 2 description</a></p> </div> <div class="feature"> <div style="display: none;" class="feature-image"> <a href="/pissed-up-brits/movie"><img src="/design/images/four-oh-four.png"></a> </div> <h2 class="feature-title"><a href="/pis/movie">Item 1</a></h2> <p style="display: none;" class="feature-description"><a href="/pis/movie">Item one description</a></p> </div> <div class="feature"> <div style="display: none;" class="feature-image"> <a href="what.com"><img src="/images/Featured/indie.png"></a> </div> <h2 class="feature-title"><a href="what.com">Item 4</a></h2> <p style="display: none;" class="feature-description"><a href="what.com">Item 4 description</a></p> </div> </div> </body> </html>

  • MySql products and categories tables using php and json

    - by Romina Mora
    I have just started learning all this coding language and the teacher is asking us to do the following. I know it may sound really easy for people who do this full time or have more time coding. The teacher is always telling us to GOOGLE everything and I have tried too many sites but I haven't found anything that helps me at all. I need to write two JSON documents (products and categories) using PHP that will dynamically read values from my MySQL database. When each document is called upon, it will return perfectly formatted JSON that will validate using http://jsonlint.com/ Honestly I don't know what to do. I don't understand PHP and now this JSON thing is making it more confusing.

  • Mapping Hilbert values to 3D points

    - by Alexander Gladysh
    I have a set of Hilbert values (length from the start of the Hilbert curve to the given point). What is the best way to convert these values to 3D points? Original Hilbert curve was not in 3D, so I guess I have to pick by myself the Hilbert curve rank I need. I do have total curve length though (that is, the maximum value in the set). Perhaps there is an existing implementation? Some library that would allow me to work with Hilbert curve / values? Language does not matter much.

  • Will VC++ MFC become obsolete in near future?

    - by AKN
    Normally people say MFC is little clumsy. It makes UI development slightly difficult to maintain since it has lot of auto generated code. It has good architecture (doc/view) but is not transparent like Win32 programming to understand how window program works in the background. So with this situation, is it good to extend the exposure on MFC programming or better to switch to .NET since for faster UI design with ease in maintenance. Is it good to continue as MFC developer or good to know .NET as well? How globally companies are looking into MFC as a technology for UI developments. Are they comfortable in supporting their developers to continue with MFC or looking for changing their development technology.

  • Can't see or add Website Data Sources in RDLC report in ASP.NET MVC

    - by RobertC
    In the RDLC report, in Design view in Visual Studio 2008, we don't see anything in the Website Data Sources tab and the button to Add New Data Source is grayed out. Only the Refresh button is enabled, and clicking it doesn't do anything. Our business logic layer returns Lists of business objects and the business logic and business object projects are both referenced by the MVC project. This is an MVC app, so there is no App_Code folder. How do we get our business objects to appear in the Website Data Sources list so we can drag and drop fields from the object onto our RDLC report?

  • How to print element values when iterating through XML document in PHP

    - by pharma_joe
    I am iterating through the results of a service call to yahoo news thus: //Send service request if (!$yahooResults = file_get_contents($yahooRequest)) { echo 'Error processing service request'; } //Read result into xml document $yahooResultXml = new DOMDocument('1.0', 'UTF-8'); $yahooResultXml-loadXML($yahooResults); //Build page include_once('components/pageHeader.php'); echo 'Search Results'; //echo $yahooResultXml-saveHTML(); //Iterate over each Result node $stories = $yahooResultXml-getElementsByTagName('Result'); foreach ($stories as $story) { //Title //Summary //Url //Source //Language //Publish Date //Modification Date } include_once('components/pageFooter.php'); Each Title is in a Title node within a Result Node. I cannot figure out how to simply echo the content of the Title node!

  • Are there programming languages taht rely on non-latin alphabets?

    - by Jaxsun
    Every programming language I have ever seen has been based on the Latin alphabet, this is not surprising considering I live in Canada... But it only really makes sense that there would be programming languages based on other alphabets, or else bright computer scientists across the world would have to learn a new alphabet to go on in the field. I know for a fact that people in countries dominated by other alphabets develop languages based off the Latin alphabet (eg. Ruby from Japan), but just how common is it for programming languages to be based off of other alphabets like Arabic, or Cyrillic, or even writing systems which are not alphabetic but rather logographic in nature such as Japanese Kanji? Also are any of these languages in active widespread use, or are they mainly used as teaching tools? This is something that has bugged me since I started programming, and I have never run across someone who could think of a real answer.

  • C++/CLI Mixed Mode DLL Creation

    - by Adam Haile
    I've got a native C++ DLL that I would like to have a C++/CLI wrapper layer for. From what I understood, if you simple added a C++/CLI class to the project, VS would compile as mixed mode, but I was apparently wrong as VS doesn't seem to be even touching the managed code. So, given a pre-existing native code-base what exactly, step-by-step, do you need to do to create a mixed mode DLL, so that I can can link into that code from any .NET language? *I need to do this because my native code uses C++ classes that I cannot P/Invoke into.

  • Entity Framework query builder methods: why "it" and not lambdas?

    - by nlawalker
    I'm just getting started with EF and a query like the following strikes me as odd: var departmentQuery = schoolContext.Departments.Include("Courses"). OrderBy("it.Name"); Specifically, what sticks out to me is "it.Name." When I was tooling around with LINQ to SQL, pretty much every filter in a query-builder query could be specified with a lambda, like, in this case, d = d.Name. I see that there are overrides of OrderBy that take lambdas that return an IOrderedQueryable or an IOrderedEnumable, but those obviously don't have the Execute method needed to get the ObjectResult that can then be databound. It seems strange to me after all I've read about how lambdas make so much sense for this kind of stuff, and how they are translated into expression trees and then to a target language - why do I need to use "it.Name"?

  • I need help translating this portion of the ECMAScript grammar?

    - by ChaosPandion
    I've been working on my own implementation of ECMAScript for quite some time now. I have basically done everything by hand to help gain a deep understanding of the process. Repeated attempts to analyze and understand this portion of the grammar have failed so I've been working on the run time instead. Now I am at a point were I will be working on object literals so I really need to polish my syntactic analyzer. Can anyone put this in terms a language parser novice could understand? My biggest source of confusion is the following: new MemberExpression Arguments This is supposed to be a member expression, but this seemingly conflicts with the following: NewExpression : MemberExpression new NewExpression Is a new expression a member expression or a left hand side expression? To be honest I am having trouble laying out the proper C# classes for the concrete grammar. MemberExpression : PrimaryExpression FunctionExpression MemberExpression [ Expression ] MemberExpression . IdentifierName new MemberExpression Arguments NewExpression : MemberExpression new NewExpression CallExpression : MemberExpression Arguments CallExpression Arguments CallExpression [ Expression ] CallExpression . IdentifierName LeftHandSideExpression : NewExpression CallExpression

  • iPhone addition to already localized nibs

    - by user168610
    I've submitted an app to the store that has been localised into a number of languages. Now it's time to update a few things, so I've added a few new components to a xib or two and modify them as IBOutlets from my code. All works great in English, but when I change to a different language it appears that my nib additions haven't been propagated through the localised nibs that already existed. (I get an unrecognised selector on a UILabel I've added). What is the correct workflow for adding new items to an already localised nib? Should a modification to the top level .xib carry through to all localised versions? Or should I unlocalize, add new components and then localise all over again? Many thanks, Bryn

  • .Net Designer assemblies, C++\C# error

    - by greggorob64
    I'm working on an designer-heavy application (using Visual C++ 2.0, but a C# solution should still be relevant). My setup is this: I have a UserControl named "Host" I'm attempting a UserControl named "Child" Child contains a property to a class whose type is defined in a different dll entirely, named "mytools.dll" Child works just fine in the designer. However, when I go to drag "child" onto "host" from the designer, I get the following error: Failed to create component 'Child'. The error message follows: 'System.io.filenotfoundexception: could not load file or assembly MyTools, Version XXXXXX, Culture=neutral ..... {unhelpful callstack} If I comment out the property in "child" that points to the class in mytools.dll, everything designs just peachy. I have the property marked with "Browsable(false), and DesignerSerializable(hidden), and it does not help. Is there a way for me to explicitly say "Don't load this dll, you won't need it in design time", or some way for me to force a dll to load from the designer programmatically? Thanks!

  • Vim: different key mapping for different window

    - by rahul
    My .vimrc file has filetype mappings for different filetypes such as : autocmd FileType sh map gf ... autocmd FileType ruby map gf ... While rewriting a program from one language to another, I have 2 splits, one with a shell script and one with ruby. I would assume that "gf" would take on its mapping based on filetype. However, it can only hold one mapping at a time. Is there any way to declare a mapping only for the existing file/window. I tried ":windo" and ":bufdo" but they work for all windows or buffers.

  • anyone know of a custom membership provider implementation that check password strength against in-b

    - by ronaldwidha
    I've got an Asp.net MVC app and before being able to go live, the IT have requested for us to comply with their password policy. The flexibility of AspnetSqlMembershipProvider doesn’t quite satisfy the requirement. The password strength and length rules are as follows: one lowercase one Uppercase one number and or special character 8 characters in length so far, aspnetsqlmembershipprovider is good... Not allowed to use: Dictionary words Names, real or fictional Plain language phrases Dates Telephone numbers Car registration numbers User IDs Postal codes Organization name Only the first 4 criteria are satisfied by the aspnetsqlmembershipprovider. Do you know of any third party products that offers this functionality (preferably in the form of a custom membership provider)?

  • Power Analysis in [R] for Two-Way Anova

    - by Thomas
    I am trying to calculate the necessary sample size for a 2x2 factorial design. I have two questions. 1) I am using the package pwr and the one way anova function to calculate the necessary sample size using the following code pwr.anova.test(k = , n = , f = , sig.level = , power = ) However, I would like to look at two way anova, since this is more efficient at estimating group means than one way anova. There is no two-way anova function that I could find. Is there a package or routine in [R] to do this? 2) Moreover, am I safe in assuming that since I am using a one-way anova power calculations, that the sample size will be more conservative (i.e. larger)?
