• Best approach to update a control after an Ajax request?

  - by Cuga

  I have a webpage that fires off an Ajax request which stores some data to a database and I want to update the webpage so that the user can see their changes have been submitted. There are at least 3 ways I can think of accomplishing this: Immediately update the webpage with plain JavaScript by grabbing the contents of the user's inputted text and immediately inserting it where it belongs. Have the ajax call return the stored text as the response, grab the response, and then insert this text where it belongs on the page using JavaScript Have the ajax call return a flag (say, true for successful db write, false otherwise), and if the flag is true, use JavaScript to grab the user's contents from the input control and insert it where it belongs elsewhere on the page Or another method not mentioned...? I don't mean this to be subjective, I just don't know which would be the best method to apply. My instinct tells me to go with the third item (return a flag, then update the field). Is this the best way? Thanks

• Java. Writing a matrix in a file using column information. ( matrix transposition )

  - by Dmitry

  Hello, everybody! I have a file in which a matrix is stored. This file has a RandomAccessFile type. This matrix is stored by columns. I mean that in an i-th row of this matrix an i-th column (of a real matrix) is stored. There is an example: i-th row: 1 2 3 4 (in the file). That means that the real matrix has an i-th column: (1 2 3 4)(is transposed). I need to save this matrix in a natural way (by rows) in a new file, which I will then open with FileReader and display with TextArea. Do you know, how to do that? If so, please help =)

• How does Contract.Exists add value?

  - by Scott Bilas

  I am just starting to learn about the code contracts library that comes standard with VS2010. One thing I am running into right away is what some of the contract clauses really mean. For example, how are these two statements different? Contract.Requires(!mycollection.Any(a => a.ID == newID)); Contract.Requires(!Contract.Exists(mycollection, a => a.ID == newID)); In other words, what does Contract.Exists do in practical purposes, either for a developer using my function, or for the static code analysis system?

• How to create GUI as inner class with WindowBuilder

  - by Tim Kemp

  I would like to use WindowBuilder in Eclipse to construct Swing GUIs. The JPanels I need to build will be inner classes in a non-GUI wrapper, like so: public class MyWrapper extends MyBaseClass { ... class MyPanel extends JPanel { ... } } So my question is this: can I construct MyPanel using WindowBuilder? If so, how should I set it up? If anyone is interested, the wrapper is an abstract base class which the plug-ins I am developing for my app must extend; deployment concerns mean that it's not really practical to put the GUIs in a separate JAR either so I pretty much have to do it this way. My current workflow, which is awful, is to build the GUI in NetBeans and paste the entire generated class into Eclipse where I connect it up to the methods in my wrapper. I am very hopeful that WindowBuilder will let me work more reliably and efficiently if I can trick it into generating code in MyPanel, not MyWrapper. Thanks

• iPhone SKD make the iPod controller appear

  - by nico

  Hi all, It's been a while I'm consulting stackoverflow, but this time I didn't find any answer :( My question is quite simple :) On an iPhone/iPod touch, play music. Double tap the home button while the music is playing. You will see appear a popup with the play/pause/next/previous buttons and a volume control. Do you know if it's possible to make this popup appear programmatically ? I mean, I would like to add a button in my app that will display the popup, avoiding the user to double tap the home button (most of them doesn't know this shortcut). Thank you in advance !

• Why Solr admin query page interprets UTF-8 as ISO-8859-1

  - by Scott Chu

  I deploy a war to my Tomcat 6.0.35 on Win7 64bit and when I use full-interface query page (I mean form.jsp) in Solr Admin to query 2 Chinese character (say it's C1C2) , the debug info shows: <lst name="debug"> <str name="rawquerystring">æ°è</str> <str name="querystring">æ°è</str> <str name="parsedquery">NEWSID:æ°è</str> <str name="parsedquery_toString">NEWSID:æ°è</str> ... You can see C1C2 becomes æ°è. I deploy same war file to Tomcat on Linux or on another Win7 64bit of my colleagues' computer, the encoding acts well. Does anyone know why and how can I avoid this problem? Thanks in advance!

• Manually Building a Tree in CakePHP

  - by mabwi

  I'm currently working on building an application in CakePHP. There's a quite extensive existing data set that's conceptually a tree, but wasn't previously stored as one. What I mean by that, is there's no real relationship defined in the data. The problem I'm having is getting it to work correctly with the CakePHP tree behaviour. Because I have to set all the values on existing data - as opposed to Cake setting up the structure as elements are inserted - I need to understand how the lft/rght values work. So, I guess the question is: How does the structure data work, specifically the lft/rght values? How do I set it up so that the data comes out rationally, without inserting them one at a time? It's a 2 level tree, with Sections and sub-sections. Thanks for the help

• Final Integration Testing for Q.A.

  - by CalebHC

  A medium sized rails app that our company has been working on is getting close to the end of development and we are going to start doing Q.A. testing on it. We've have been writing unit, functional and integration tests all along and our test coverage is about 99% (even though that really doesn't mean anything). We feel like we have a pretty good test suite but I was wondering if we should be writing final integration tests for every little action we are going to do during our Q.A. process. If so, would using Shoulda or Cucumber be a good idea? We haven't used either of those testing tools yet, but they sound really great. Any ideas or thoughts would be really helpful. Thanks

• Need help deciphering JQuery example

  - by chobo

  I just started learning JQUery and OO Javascript, so I am trying to figure out which belongs to which and what they do. I came across this code in the JQuery documentation (function($sub) { $sub // a subclass of jQuery $sub === jQuery; //= false $sub.fn.myCustomMethod = function(){ return 'just for me'; } $sub(document).ready(function() { $sub('body').myCustomMethod(); //= 'just for me' }); })(jQuery.subclass()); Questions: Why is (function surrounded by () ? What does this mean (jQuery.subclass()); ? Is this a JQuery thing or part of regular javascript? Thanks

• Can I install Whizzy for Emacs on a Mac (is Mac OS X a unix environment)?

  - by Vivi

  I think my question is pretty stupid, but here it goes: I am using Aquamacs, and I want to install the Whizzy mode. The website for Whizzy says that "it is designed for Unix platforms". I read that Mac OS X is unix certified, but does that mean I can install Whizzy on my mac? If yes, can I install and use it with Aquamacs or do I have to use the Emacs running from the terminal? PS: I don't know whether this question should be posted here or on SuperUser, but as Emacs users seem to hang out here more often, this is the place I chose.

• OpenGLES iPhone Depth Blending problem

  - by user359103

  Hi, I am trying to make an OpenGLES 2.0 cube application. The idea was to have a texture (with an alpha 75%) applied to all 6 faces of the cube. This would mean that even if I rotate the cube i would be able to see all 6 faces at any given frame. Now I have enabled depth test(my app needs this!!) and blending. The Depth func is LEQUAL and blend func is SRC_ALPHA, ONE_MINUS_SRC_ALPHA. Now, the issue is that at some cube faces don't show the underlying faces. I am not able to understand this because the logic works fine with the other cube faces. Just for the record, I have disabled CULL_FACE. Thanks in advance. Regards, Puzzler

• Problem with default member functions of class in C++ (constructor, destructor, operator=, copy cons

  - by Narek

  We know that compiler generates some member functions for user-defined class if that member functions are not defined but used, isn't it. So I have this kind of code: class AA { }; void main() { AA a; AA b(a); a = b; } This code works fine. I mean no compiler error. But the following code.... class AA { int member1; int member2; }; But this code gives an run time error, because variable "a" is used without being iniltialized!!! So my question is this: when we instantiate an int, it has a value. So why the default constructer doesn't work and by using those two int numbers initializes variable "a"??

• Show me some cool python list comprehensions

  - by christangrant

  One of the major strengths of python and a few other (functional) programming languages are the list comprehension. They allow programmers to write complex expressions in 1 line. They may be confusing at first but if one gets used to the syntax, it is much better than nested complicated for loops. With that said, please share with me some of the coolest uses of list comprehensions. (By cool, I just mean useful) It could be for some programming contest, or a production system. For example: To do the transpose of a matrix mat >>> mat = [ ... [1, 2, 3], ... [4, 5, 6], ... [7, 8, 9], ... ] >>> [[row[i] for row in mat] for i in [0, 1, 2]] [[1, 4, 7], [2, 5, 8], [3, 6, 9]] Please include a description of the expression and where it was used (if possible).

• Resize a DIV when its text changes

  - by Antonios

  I wanted to build a custom html button without using any solution like bootstrap etc. but from scratch. I decided to use a div to build my button with very good results. However, when the text changes its length that does not mean the div will change its width as well. Should I approach this using javascript or is there a CSS solution I am missing. Apologies for missing code: div { position: relative; width: 121px; height: 30px; } I need a minimum width and not a dynamic this is why I used a fixed one. In case there is not a CSS alternative then I will use a javascript approach.

• Is there any free, open source php CMS\framework for described case?

  - by Ole Jak

  I want that cms\framework to create me tables like "Users" "Cameras" and so on and declare classes and simple default methods for them (like paged sql relults and so on). I mean I say to it: I want Users to have ID, SpecialNumber and Name Flilds. and I want to get from it class for table generation (to call it once) and class containing methods such as Search by ID, SpecialNumber and Name, Create User, Delit User and so on functions. Is there any framework/cms like this for working with CODE not ui's and so on... so to say PHP generator or something... The result should be as that framework free as possible. So Is there any free, open source php CMS\framework for described case?

• scala xml rewrite rule (or, simple pattern help)

  - by williamstw

  I'm missing some fairly simple syntax I gather. I'm trying to rewrite an element label to something else and keep everything else intact. object htmlRule extends RewriteRule { override def transform(n: Node): Seq[Node] = n match { case Elem(prefix, "document", attribs, scope, child@_*) => Elem(prefix, "html", attribs, scope, child) case other => other } } Now, I ask for an explanation of two things: 1) What exactly does "child@_*" mean in plain English? 2) How can I capture the value of "child@_*" and just let it pass right through to the new element? Currently, I get the following error, which makes sense. [error] found : Seq[scala.xml.Node] [error] required: scala.xml.Node [error] Elem(prefix, "html", attribs, scope, child) I'm not wedded to this either, so if there's a better way to simply change the element name of a specific node, let's here it... Thanks, --tim

• How to interpret situations where Math.Acos() reports invalid input?

  - by Sean Ochoa

  Hey all. I'm computing the angle between two vectors, and sometimes Math.Acos() returns NaN when it's input is out of bounds (-1 input && input 1) for a cosine. What does that mean, exactly? Would someone be able to explain what's happening? Any help is appreciated! Here's me method: public double AngleBetween(vector b) { var dotProd = this.Dot(b); var lenProd = this.Len*b.Len; var divOperation = dotProd/lenProd; // http://msdn.microsoft.com/en-us/library/system.math.acos.aspx return Math.Acos(divOperation) * (180.0 / Math.PI); }

• Do (statically linked) DLLs use a different heap than the main program?

  - by happy_emi

  I'm new to Windows programming and I've just "lost" two hours hunting a bug which everyone seems aware of: you cannot create an object on the heap in a DLL and destroy it in another DLL (or in the main program). I'm almost sure that on Linux/Unix this is NOT the case (if it is, please say it, but I'm pretty sure I did that thousands of times without problems...). At this point I have a couple of questions: 1) Do statically linked DLLs use a different heap than the main program? 2) Is the statically linked DLL mapped in the same process space of the main program? (I'm quite sure the answer here is a big YES otherwise it wouldn't make sense passing pointers from a function in the main program to a function in a DLL). I'm talking about plain/regular DLL, not COM/ATL services EDIT: By "statically linked" I mean that I don't use LoadLibrary to load the DLL but I link with the stub library

• C++: How do I pass a function(without knowing its parameters) to another function?

  - by Ninja

  Hi all. I'm trying to create a function that will store and repeat another function given as a parameter for a specific amount of time or repeats given. But when you want to pass a function as a parameter you have to know all of its parameters before hand. How would I do if I wanted to pass the function as one parameter, and the parameters as another? void AddTimer(float time, int repeats, void (*func), params); // I know params has no type and that (*func) is missing parameters but it is just to show you what I mean Thanks in advance

• How to know if your Unit Test Fixture is “right-sized”?

  - by leeand00

  How do you know if you "Test Fixture" is right-sized. And by "Test Fixture" I mean a class with a bunch of tests in it. One thing that I've always noticed with my test fixtures is that they get to be kind of verbose; seeing as they could also be not verbose enough, how do you get a sense of when your unit tests are the right size? My assumption is that (at least in the context of web development) you should have one test fixture class per page. I know of a good quote for this and it's: "Perfection is achieved, not when there is nothing left to add, but when there is nothing left to remove." - Antoine de Saint-Exupery.

• Printing Work Items in TFS

  - by user351671

  Hi, I am looking for a fancy way the print individual work items in TFS. OK ... maybe not the work item directly but I need to produce printable forms based on data on a work item. And by fancy I mean: header, footer, formatting, tables maybe ... stuff like that. No, I am not trying to print a list of work items, read carefully, I need an output based on a single work item. For those who are wondering "Why on earth do you need that?" I should say: We are keeping everything on TFS around here. (For now only software development stuff, but I am thinking bigger...) Sometimes somethings need to be on hard copy, to be signed for instance, and that is why I need printable forms.

• Unicode string handling using Windows API

  - by DeadMG

  I always assumed that Unicode string handling was some dark art. However, I've seen that the Windows API has functions for comparing Unicode strings, for example. Does that mean that it's actually feasible to write a Unicode string class that can perform simple actions like sorting, equality comparison, and extraction from a file? Or are there hidden gotchas in the use of these functions that makes it actually a really bad idea? I'm just looking at libraries like ICU and they seem incredibly over-complicated compared to what a Unicode string class backed by the Windows API could actually look like, which would resemble the Standard string classes quite closely.

• Zend_Form: Is this really the way we should be doing things?

  - by Francis Daigle

  OK. I understand how to use Zend_Form and it's implementation of the decorator pattern. My question is, is this the best way to be going about creating forms? Shouldn't a documents forms be left to to the front-end rather than generating forms programmatically? Doesn't this kinda violate the whole idea of keeping things separate? I mean, really, even providing that you have a good understanding of the methodology being employed, does it really save one that much time? I guess what I'm looking for is some guidance as to what might be considered 'best practice'. I'm not saying that Zend_Form doesn't have it's place, I'm just wondering if it should be used in all cases (or not). And this has nothing to do with validation. I'm just thinking that something more akin to using the 'ViewScript' approach might be more appropriate in most cases. Your thoughts?
