• What features are important in a programming language for young beginners?

  - by NoMoreZealots

  I was talking with some of the mentors in a local robotics competition for 7th and 8th level kids. The robot was using PBASIC and the parallax Basic Stamp. One of the major issues was this was short term project that required building the robot, teaching them to program in PBASIC and having them program the robot. All in only 2 hours or so a week over a couple months. PBASIC is kinda nice in that it has built in features to do everything, but information overload is possible to due this. My thought are simplicity is key. When you have kids struggling to grasp: if X>10 then <DOSOMETHING> There is not much point in throwing "proper" object oriented programming at them. What are the essentials needed to foster an interest in programming?

• WPF 4.0 Font Rendering Issue

  - by Tom Allen

  I'm getting a weird rendering issue with WPF 4 applications in the way they render some of the text as it's stretching it and making it very narrow. .net 3.5: .net 4.0: At first I thought it could be a problem with the font, but I'm also seeing the same problem in the Blend 4 beta: I'm running XP SP3, Visual Studio 2010 Professional and everything's as up to date as it can be. I'm not noticing any such problems with Silverlight 4 apps I have built on the same machine... Anyone else seen this or know why it's happening?

• How to configure build numbers in Visual Studio to enable dll comparison

  - by jaminto

  Hi Everyone- I am building a C# solution in Visual Studio 2008 that has several projects and project dependencies. I am looking for a way to change dll version numbers ONLY when the code that builds the project changes. I currently use Beyond Compare to compare my locally built version to the production file system. The goal is to ONLY deploy updated dlls. I am using autoincrementing version numbers, and each time you open visual studio and do a build, all dll version numbers increment. The same goes for a full solution rebuild and when a different developer does a build and tries to deploy. Is there a way that i can configure Visual Studio to ONLY increment the build number based on changed file contents? Is there an add in that will do this?It seems a binary comparison of these files will also fail because of the different version numbers within the dlls. Does anyone know of a better tool compare only the contents of dlls?Thanks in advance.

• Create javadoc with multiple src dirs

  - by Ed Marty

  I have a Util package with source files in three seperate directories, defined like so: src/com/domain/util src/Standard/com/domain/util src/Extended/com/domain/util The package is built with the first set of files and either one of the second or third set, to create a total of two different implementations of the same interface. Now, I want to generate javadoc based on those files. How can I specify that? What I really want to do is javadoc com.domain.util -sourcepath ./src;./src/Standard to build the javadoc for the standard util package, and javadoc com.domain.util -sourcepath ./src;./src/Extended to build the javadoc for the extended util package. This doesn't work. The only way I've found so far to actually make it work is to merge the directory structure of the common classes and the Standard classes into another location and run with that for the standard javadoc, then do the same for the Extended package. Is there another way?

• ASP.NET Development Server - Empty webResource.axd after conversion from 2.0 to 3.5

  - by David Casey

  I have moved a project from asp.net 2.0 to 3.5. The original project was using the atlas ajax extensions so I have modified the code to use the built in ajax features in 3.5. When running the project within the dev environemnt (VS2008 on Vista Business SP1) and using the asp.net dev server I receive javascript errors such as WebForm_PostBackOptions which point to a missing handler/module. If I deploy the project and run it stand alone within IIS or if I use Fiddler2 while running in VS2008 I do not see the errors and fiddler shows that the axd files are being downloaded correctly. Also deploying to a 2003 server does not show any issues. I could just carry on and forget this as it works when deployed but I would like to understand what is happening. Has anyone got an ideas as to what is going on here and how to get the same results accross all environments?

• Where should I store my application data?

  - by joebeazelman

  I have an application that needs to store data. Currently, I am using the built-in Application Settings to do it, but it only gives me two choices: application and user scopes. Ideally, I want a "local" scope that allows the application to run under another user and still find its data rather than recreate it for that user. The application scope can do this, but it's read only. The application data will be changed by the user. It's OK if only the administrator is allowed to make changes to the data. As you probably can guess, I have an administration tool that allows the user to change the data and windows service runner that reads the data and does something with it. It would be great if the windows service runner access the data created by the administration tool.

• VS 2010 MVC Formatting

  - by Brian

  Hello, MVC is formatting my code horribly, and I was wondering if you can turn it off? I feel the answer is no, but I was hoping VS 2010 had built in a setting... Here's what its formatting as: <% if (org.UserKey.HasValue) { %> <%= org.Reference(i => i.UserReference).Email%> <% } else { %> <%= org.UserEmail%> <% } %> I want the beginning brackets on the same line as the if and the else... Thanks.

• image rendering issue

  - by burkejam71

  I am running Apache/2.2.3 (CentOS). For some reason certain images, jpg, gif, or png will show up as byte code when accessed directly on the server. Firefox 3 and Safari both think the content type is text/html. IE I believe has something built in to recognize it is an image and ignore the content type and renders the image correctly regardless. I can't seem to find anyone else with this issue. An example of this can be found at http://www.thedacs.com/admin/gp/userfiles/image/gp28%5Fimg%5F01.jpg but the image below on same server the image is rendered correctly (use same path from above) Fig3mod.jpg The first image works fine in Photoshop CS, Illistrator, GIMP, Paint.net,and any other image editing software. I have tried everything when editing the images from trying multiple file formats to print screens and cropping to create a new image to lose old image meta data. Can anybody help?

• How to prevent form submission for a form using onchange to submit the form when certain values are

  - by Terrence Brannon

  I have a form I have built: <form class="myform" action="cgi.pl"> <select name="export" onchange='this.form.submit()'> <option value="" selected="selected">Choose an export format</option> <option value="html">HTML</option> <option value="csv">CSV</option> </select> </form> Now, this form works fine if I pull down and select "HTML" or "CSV". But if I hit the back button and select "Choose an export format", the form is submitted, even though I dont want it to be. Is there any way to prevent form submission for that option?

• How do you build a Request-Response service using Asyncore in Python?

  - by Casey

  I have a 3rd-party protocol module (SNMP) that is built on top of asyncore. The asyncore interface is used to process response messages. What is the proper technique to design a client that generate the request-side of the protocol, while the asyncore main loop is running. I can think of two options right now: Use the loop,timeout parameters of asyncore.loop() to allow my client program time to send the appropriate request. Create a client asyncore dispatcher that will be executed in the same asyncore processing loop as the receiver. What is the best option? I'm working on the 2nd solution, cause the protocol API does not give me direct access to the asyncore parameters. Please correct me if I've misunderstood the proper technique for utilizing asyncore.

• Where to put the default destroy in the jQuery UI 1.8.1 widget's destroy function

  - by dominicminicoopers

  Ok, I'm having a slight bit of confusion writing my own jQuery UI widget plugins. The problem lies in the destroy function. In the docs, it says to put the default destroy first then write other things particular to the widget after it. $.Widget.prototype.destroy.apply(this, arguments); // default destroy // now do other stuff particular to this widget See http://jqueryui.com/docs/Developer_Guide However in their example scripts (those being the actual pluings for jQuery Ui released code, does it the opposite. The $.Widget.prototype.destroy.apply(this, arguments); is at the end of the function. See http://dev.jqueryui.com/browser/trunk/ui/jquery.ui.progressbar.js (and all of the other built in widgets as well) So which is it? The way the current widgets are written, or by the explanation in the code comment in the Developer_Guide?

• create a simple pdf report from html

  - by opensas

  I'm looking for a way to generate pdf files from html In order to make simple tabular reports I would need the following features table rendering variable page size repeating headers / footers on every page calculated page number / total page css support would be nice I know there have been many similar questions in stackoverflow, but I don't know if there's a product that supports the aforementioned features... Ideally, the source would be a plain and simple well built html with css, (I'm building the html files, so I can adapt to the products needs, that is, it won't have to render every piece of html crap you can throw at a browser) and with some custom tags to configure headings, footer, page size, etc... then I would run a command line to convert it from html to pdf. I think http://www.allcolor.org/YaHPConverter/ does something like that

• International Assist on iPhone

  - by john-gosset

  Does anyone know if the International Assist feature on the iPhone works when dialing a number using the tel:// URL scheme from an application? For those unfamiliar, IA automatically prefixes the "+1" to US numbers when using the iPhone internationally. I know that this works when dialing from either the built-in Contacts or Phone apps, but can't find anything stating that it works when dialing numbers from an application. Also, is there any documentation as to whether this feature is included on Canadian (Rogers) or European iPhones (or is it only used by AT&T)? If IA does not work when dialing with a custom app, can someone point to the API that would allow me to detect that the use is roaming on a foreign network so I can essentially duplicate IA's functionality? Any help greatly appreciated!

• Checking a checkbox node programmatically with jsTree

  - by Raj

  In a tree built with jsTree, I have the text within the <a> tag sitting in a variable. I would like to check that node. How can I do so? I am currently finding that node, using jQuery, and altering its class. However, this does not repair the parent node by making the parent undetermined in its class. I tried doing $('.colors').jstree("checkbox_repair"), but that didn't seem to do anything. It would be great if someone could actually answer both those questions, since they are related to the same problem. Here is a jsFiddle, illustrating the issue-- http://jsfiddle.net/thapar/5XAjU/

• codeigniter site, swfobject not fully loading swf

  - by Joe

  I am having a strange problem. I have a view that is supposed to load a swf. The swf was compiled with Flex and the mxml preloader displays but it loads a blank screen. When I path directly to the file it loads fully and works fine. Other possibly relevant information: The swf makes calls through GET requests to the database the site is built with codeigniter I'm using swfobject to load the swf you can see it in all it's busted glory here: http://thetoad.flattoads.com:16080/~iopdev/CI/index.php?c=moodtotem&m=index I'm going bonkers over this!

• Wordpress Digg-Like Voting System Plugin

  - by mikemick

  I just found out about BuddyPress (a collection of plugins that convert a WordPress MU install into a social network) and now I was wondering if there are any Digg-like voting plugins for WordPress. This would eventually integrate into a BuddyPress website, where the site members would submit, vote and comment on stories (much like Digg). I have a feeling I will end up having to build this from scratch, but since the site will be built on WordPress, I was wondering if there were any plugins already available that add this functionality. So far I have come up empty in my search. I did find a Wordpress blog that had this functionality WpVote. It even creates thumbnails of the story webpage automatically (I'm assuming) using websnapr. I browsed through the page source and didn't seem to find any hints of a WP plugin that they are using.

• Thumbnails from HTML pages created and used automatically in web application

  - by Jesper Rønn-Jensen

  I am working on a Ruby on Rails app that visualizes product trees. The tree is built of nodes an everything is rendered in HTML/CSS3. Some of the products make several hundred SQL queries as the tree builds up (up to 800 queries on the biggest tree). I'd like to have small thumbnails of each tree to present it on an index page. So rendering each tree once again and modifying CSS to make a tiny representation is an option. But i think it's probably easier to generate thumbnails, crop, cache, and show these on the index page. Any ideas on how to do this? Any links/articles/blog posts that could help me?

• IBOutlet UILabel do not get resized

  - by Leonardo

  HI all, I have designed a view in Interface Builder and connected correctly with its controller. There some UILabel in it that are going to be filled with lot of text. But, even if I have declared "word wrap" and set line to 0 in IB, I can display only first line. I notice that if I increase the height of the UILabel in IB, all the text display properly in multi line, but I cannot do that because text may vary. Shouldn't the UILabel resize itself to fit all the text ? Also, if I built the UILabel programmatically I can succesfully accomplish a word wrap, why cannot do the same with IB ? What am I doing wrong ? thanks Leonardo

• IE6 - body shrink on hover / z-index change

  - by Kasper

  I'm debugging a site to make it work for IE6 (god, please, let this be the last time). I've gotten pretty far with getting the the layout look right. There's just one more thing bugging me. Some elements like links, when they get hovered, the body of the site shrinks. I have built a dropdown with javascript. When it should show, the body of the site shrinks. There is a slideshow, made with javascript, which changes the z-index of the images, everytime it changes the z-index, the body shrinks. Now I found some information that IE6 creates this specific shrinking behaviour when using a fixed position element. But this is not the case. Someone here have some ideas for solving this? Thanks!

• Integrate forum software into existing Zend site

  - by mrbubblesort

  I've searched around and haven't really found anything on this, so maybe someone here has tried this before. My company already has a website built with Zend, and we'd like to add in a forum as well. All I really need is something that will work with postgresql and has foreign language support (particularly Japanese, but if worst comes to worst, I'll just translate it myself). phpBB fits all my needs though. Is it possible to get the two working together? Or is there another forum software that'll work with Zend? Or is it better to just build the thing from scratch? Thanks!

• How to make an NSOutlineView indent multiple columns?

  - by Rinzwind

  What would be the easiest or recommended way for making an NSOutlineView indent multiple columns? By default, it only indents the outline column; and as far as I know there is no built-in support for making it indent other columns. I have an NSOutlineView which shows a comparison between two sets of hierarchical data. For visual appeal, if some item in the outline column is indented, I'd like to indent the item on the same row in another column by the same indentation amount. (There's also a third column which shows the result of comparing the two items, this column should never be indented.) Can this only be achieved by subclassing NSOutlineView? And what would need to be overridden in the subclass? Or is there an easier way to get it to indent multiple columns?

• Question About MP4(AAC) Binary Tree

  - by DeanMc

  I'm in the very early stages of working on a tag editor for mp4 files and more specifically iTunes AAC ones. After doing some snooping around it seems that the file's structure is not as complicated as I first thought and is built in a sort of tree like the following 4 Bytes [Atom Length] 4 Bytes [Atom Name] X Bytes [Atom Data] An atom's data is as large as the length and can contain either Data(information) or another atom. What I am trying to work out is how one determines if the data is information or an actual atom. Any insight would be much appreciated.
