• Using a constructor for return.

  - by Fecal Brunch

  Hi, Just a quick question. I've written some code that returns a custom class Command, and the code I've written seems to work fine. I was wondering if there are any reasons that I shouldn't be doing it this way. It's something like this: Command Behavior::getCommand () { char input = 'x'; return Command (input, -1, -1); } Anyway, I read that constructors aren't meant to have a return value, but this works in g++. Thanks for any advice, Rhys

• Using Google Common Collection in GWT

  - by Jeeyoung Kim

  This is a simple problem, but I'm having problems with it... I'm trying to use Google common collection's Objects.equal() method in a GWT client code, but I'm keep getting the error "20:12:10.001 [ERROR] [gwt_regex] Line 39: No source code is available for type com.google.common.base.Objects; did you forget to inherit a required module?" Tried to Google for the answer, but couldn't find any answer regarding this - everyone just said "Google collection should work off the box with GWT".

• Using the Callback Method on a View in ASP.NET MVC

  - by Tony

  I have a master page with that code: public string CallbackMethod; protected void Page_Load(object sender, EventArgs e) { CallbackMethod = Page.ClientScript.GetCallbackEventReference(this, "message", "Dodanie", "context", true); } /other code here/ then, in the View (which is based on that master page) I need to invoke the CallbackMethod string, but the problem is, the framework firstly renders the View, and then invokes the Page_Load method. As the obvious result, the error appears: the name 'CallbackMethod' does not exist in the current context. How do I fix this?

• Learning to write organized and modular programs

  - by Peter

  I'm a computer science student, and I'm just starting to write relatively larger programs for my coursework (between 750 - 1500 lines). Up until now, it's been possible to get by with any reasonable level of modularization and object oriented design. However, now that I'm writing more complex code for my assignments I'd like to learn to write better code. Can anyone point me in the direction of some resources for learning about what sort of things to look for when designing your program's architecture so that you can make it as modularized as possible?

• C# Copying instance variable to local variable in functions of same class

  - by NickLarsen

  I have been looking through some code on an open source project recently and found many occurrences of this kind of code: class SomeClass { private int SomeNumber = 42; public ReturnValue UseSomeNumber(...) { int someNumberCopy = this.SomeNumber; if (someNumberCopy > ...) { // ... do some work with someNumberCopy } else { // ... do something else with someNumberCopy } } } Is there any real benefit to making a copy of the instance variable?

• Get preferences in AppWidget Provider

  - by Brian515

  Hi all, I seem to be having trouble reading preferences from my AppWidgetProvider class. My code works in an Activity, but it does not in an AppWidgetProvider. Here is the code I am using to read back a boolean: SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); boolean autoreplyon = settings.getBoolean("autoreplyon", false); However, I get the "The method getSharedPreferences(String, int) is undefined for the type widget" error (widget is the name of my AppWidgetProvider class). Thanks in advance for any suggestions!

• Does Apple approve a kind of mark-up language for AppStore?

  - by Eonil

  AppStore now rejects applications made with non-Apple like languages. (with modified contract) However, is it allowed using declarative mark-up language formed with XML? (like XHTML, but different schema) The declarative mark-up is a code too, but not a script or logic code. Just a passive, static data, but forms some layout and part of an application logic.

  Tried doing http://davidwparker.com/2008/09/17/site-wide-announcements-in-rails-using-jquery-jgrowl/ Am really bad with JS.

Really lost on this one.

• Adding metadata attributes to MySQL table

  - by Jack

  I would like to add custom attributes to a MySQL table which I can read via php. These attributes are not to interfere with the table itself - they are primarily accessed by php code during code generation time and these attributes HAVE to reside in the DB itself. Something similar in concept to .NET reflection. Does MySQL support anything like this? Thanks.

• Creating PDF Invoices - Are there any templating solutions?

  - by smashedmercury

  Our company is looking to integrate invoices into a new system we are developing. We require some a solution to create a layout of the invoice and then convert to pdf. We have considered just laying out the invoice in html/css then converting to pdf. We have also considered using SVG-PDf conversion. Both of these solutions integrate well into our existing templating language used for our web application. Historically we have been a Microsoft based business and used Crystal Reports for such a task but we are looking an open source Linux solution for this project. Does any one have any suggestions of an approach or technology we could use for such a task?

• Want to show <embed> and <object> tags from YUI editor as a text rather then a video.

  - by user208678

  I am using YUI rich text editor on my website (php/mysql), so that a user may enter textual matter/articles through it. But if a user copies and paste some embed code in the textarea, from any video sites like youtube, it should get saved as a text block and not as a playing video when showing the text content on the browser. Now YUI automatically converts the characters into html entities which ever is needed. Please note that if I put a new line in the yui editor (by pressing "Enter" key), it will be converted into a "<br>" tag in the background and this will not get html entity encoded when passing the value to my backend PHP script. But If I copy and paste any embed tag or for that reason any valid html tags in the textarea, it will be html entity encoded by YUI. Now to support UTF-8 characters, I am using a function (DBVarConv) in my php script before saving it into my database. The code for the function is given below function DBVarConv($var,$isEncoded = false) { if($isEncoded) return addslashes(htmlentities($var, ENT_QUOTES, 'UTF-8', false)); else return htmlentities ($var, ENT_QUOTES, 'UTF-8', false); } $myeditorData = DBVarConv($myeditorData, true); // Save $myeditorData in database. While showing the data in the browser, I am using another function called "smart_html_entity_decode". The code is given below. function smart_html_entity_decode($text, $isAddslashesUsed = false) { if($isAddslashesUsed) $tmp = stripslashes(html_entity_decode($text, ENT_QUOTES, 'UTF-8')); else $tmp = html_entity_decode($text, ENT_QUOTES, 'UTF-8'); if ($tmp == $text) return $tmp; return smart_html_entity_decode($tmp, $isAddslashesUsed); } // Get $myData from database $myData=smart_html_entity_decode($myData, true); echo $myData; The problem is that in doing so, it is also decoding the embed and object tags from their html encoded entities and as a result my obejct tags are shown as a video and not as a simple text. Try using the text editor at tumblr.com. If you paste an embed code in the editor, it will be shown as a text block not as a video. I am trying to build the same functionality on my website with UTF-8 support. Any help will be highly appreciated.

There are also positive and negative infinity for floats, should i use those instead? if so, how do i denote that in my code?
