• How do I put my return data from an asmx into JSON? I'm having trouble finding decent literature

  - by jphenow

  I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance.

• Session in Iframe working in Firefox but not in Internet Explorer

  - by Younes

  Im trying to get a form working in Internet Explorer. I see that when i submit this form in Firefox I can start a session and send my webbrowser to the right page based on that Session. In Internet Explorer however when i'm debugging the $_SESSION i retrieve an empty array back, this means that in Internet Explorer the session isn't started on my second page. This is the code i'm using to print the session on my second page: session_start(); //unset($_SESSION['bp_email']); include("includes/_dbconnect.php"); print_r($_SESSION); die();

• Uploading a picture to a album using the graph api

  - by kielie

  Hi guys, I am trying to upload an image to a album, but it's not working, here is the code I am using, $uid = $facebook->getUser(); $args = array('message' => $uid); $file_path = "http://www.site.com/path/to/file.jpg"; $album_id = '1234'; $args['name'] = '@' . realpath($file_path); $data = $facebook->api('/'. $album_id . '/photos', 'post', $args); print_r($data); This code is in a function.php file that gets called when a user clicks on a button inside of a flash file that is embedded on my canvas, so basically what I want it to do is, when the flash takes a screen shot and passes the variable "image" to the function, it should upload $_GET['image'] to the album. How could I go about doing this? Thanx in advance!

• layout messed up once spinner has entries

  - by AndyAndroid

  Hello, I have <LinearLayout android:id="@+id/LinearLayoutPlayer" xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Spinner android:id="@+id/Spinner01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="100"></Spinner> <ToggleButton android:text="@+id/ToggleButton01" android:id="@+id/ToggleButton01" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_weight="1"></ToggleButton> </LinearLayout> Which displays a spinner and next to it a toggle button. Everything okay so far. Of course the spinner need some entries, so I add to the spinner the attribute: android:entries="@array/myentries" The problem now is that the toggle button is a bit lower than the spinner and the botton of the toggle button is cut off, maybe 3 or 5 lines of pixels. Anyone an idea what is wrong here? Android is version 2.2 Thanks!

• DataView Vs DataTable.Select()

  - by Aseem Gautam

  Considering the code below: Dataview someView = new DataView(sometable) someView.RowFilter = someFilter; if(someView.count > 0) { …. } Quite a number of articles which say Datatable.Select() is better than using DataViews, but these are prior to VS2008. Solved: The Mystery of DataView's Poor Performance with Large Recordsets Array of DataRecord vs. DataView: A Dramatic Difference in Performance So in a situation where I just want a subset of datarows based on some filter criteria(single query) and what is better DataView or DataTable.Select()?

• .NET Regular expressions on bytes instead of chars

  - by brickner

  Hi, I'm trying to do some parsing that will be easier using regular expressions. The input is an array (or enumeration) of bytes. I don't want to convert the bytes to chars for the following reasons: Computation efficiency Memory consumption efficiency Some non-printable bytes might be complex to convert to chars. Not all the bytes are printable. So I can't use Regex. The only solution I know, is using Boost.Regex (which works on bytes - C chars), but this is a C++ library that wrapping using C++/CLI will take considerable work. How can I use regular expressions on bytes in .NET directly, without working with .NET strings and chars? Thank you.

• C++ Microsoft SAPI: How to set Windows text-to-speech output to a memory buffer?

  - by Vladimir

  Hi all, I have been trying to figure out how to "speak" a text into a memory buffer using Windows SAPI 5.1 but so far no success, even though it seems it should be quite simple. There is an example of streaming the synthesized speech into a .wav file, but no examples of how to stream it to a memory buffer. In the end I need to have the synthesized speech in a char* array in 16 kHz 16-bit little-endian PCM format. Currently I create a temp .wav file, redirect speech output there, then read it, but it seems to be a rather stupid solution. Anyone knows how to do that? Thanks!

• Difference between two commands of fetching Shopping Cart Items in Magento

  - by Knowledge Craving

  In Magento, if you need to get / fetch the Shopping Cart's Item details, you can do it in any of the two possible ways, which will provide you with all the shopped Items in an array:- $cartItems1 = $cart->getQuote()->getAllItems(); $cartItems2 = $cart->getItems()->getData(); But before using any one of the above two methods, you need to initialize the shopping cart object as:- $cart = new Mage_Checkout_Model_Cart(); $cart->init(); Can anyone please describe in details as to what the two options provide & their differences between each other, along with their possible usage. In any more such option is available in Magento, can anyone please highlight it?

• Fastest method for SQL Server inserts, updates, selects from C# ASP.Net 2.0+

  - by Ian

  Hi All, long time listener, first time caller. I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

• How can I capture multiple matches from the same Perl regex?

  - by Sho Minamimoto

  I'm trying to parse a single string and get multiple chunks of data out from the same string with the same regex conditions. I'm parsing a single HTML doc that is static (For an undisclosed reason, I can't use an HTML parser to do the job.) I have an expression that looks like: $string =~ /\<img\ssrc\="(.*)"/; and I want to get the value of $1. However, in the one string, there are many img tags like this, so I need something like an array returned (@1?) is this possible?

• Drag and Drop to explorer causing invalid FORMATETC (DV_E_FORMATETC) error

  - by JustABill

  I'm trying to use this excellent example to implement dropping virtual files into Windows Explorer. However, I'm stymied by this error. Towards the bottom, inside void System.Runtime.InteropServices.ComTypes.IDataObject.GetData(ref System.Runtime.InteropServices.ComTypes.FORMATETC formatetc, out System.Runtime.InteropServices.ComTypes.STGMEDIUM medium) on the first call to ((System.Runtime.InteropServices.ComTypes.IDataObject)this).GetDataHere(ref formatetc, ref medium); I'm getting back a DV_E_FORMATETC error. As far as I can tell, all the elements of the FORMATETC struct that are being passed in are valid: cfFormat is "Shell IDList Array" (-16141), ptd is 0, dwAspect is DVASPECT_CONTENT, lindex is -1, and tymed is TYMED_HGLOBAL. I'm kind of confused how there'd be a problem anyway, since this was generated by explorer. I know very little about COM interaction, so any help would be greatly appreciated.

• implicit parameter definition in class

  - by coubeatczech

  implicit val odkaz = head; def vypis(implicit odkaz:Prvek):String = { odkaz match{ case null => "" case e => e.cislo + " " + e.pocet + "\n" + vypis(e.dalsi) } } ... def main(args:Array[String]){ val q = new MyQueue() // insert some values println(q.vypis) } This method(vypis) is a member of an queue-class so I'll always want to implicity start the recursion from the start of the queue, when calling the method from outside. Is there a way how to write it, that the method from outside calling, there's no paramter, but in inside, there's a parameter - for recursion...? The compiler complains that the parameter is not defined when called from outside

• Helper functions & prototype methods to replace heavy frameworks?

  - by Rob

  All frameworks aside, what are some of the common helper functions/prototype methods you use on a daily basis? Please note I am not arguing against frameworks. I've simply found that the majority of what I do on a daily basis can, most often, be done with a few dozen Array, String and Element.prototype methods. With the addition of a few helper functions like $ (getElementsById) and $$$ (getElementsByClass), I am able to satisfy some of the core benefits, however basic, of a much heavier framework. If you were to collect a small library of basic methods and functions to replace the core functionality of some of the popular frameworks, what would they be?

• analysis Big Oh notation psuedocode

  - by tesshu

  I'm having trouble getting my head around algorithm analysis. I seem to be okay identifying linear or squared algorithms but am totally lost with nlogn or logn algorithms, these seem to stem mainly from while loops? Heres an example I was looking at: Algorithm Calculate(A,n) Input: Array A of size n t?0 for i?0 to n-1 do if A[i] is an odd number then Q.enqueue(A[i]) else while Q is not empty do t?t+Q.dequeue() while Q is not empty do t?t+Q.dequeue() return t My best guess is the for loop is executed n times, its nested while loop q times making NQ and the final while loop also Q times resulting in O(NQ +Q) which is linear? I am probably totally wrong. Any help would be much appreciated. thanks

• What's the simplest way to create a Zend_Form tabular display with each row having a radio button?

  - by RenderIn

  I've seen simple examples of rendering a Zend_Form using decorators, but I'm not sure they are able to handle the issue I'm facing very well. I query the database and get an array of user objects. I want to display these users as a form, with a radio button next to each of them and a submit button at the bottom of the page. Here's roughly what the form will look like: [user id] [email] [full name] ( ) 1 [email protected] Test user 1 (*) 2 [email protected] Test user 2 [SUBMIT] Is this something achievable in a reasonably straightforward way or do I need to use the ViewScript partial?

• Automated testing of a website for IE7 javascript errors?

  - by Andreas Bonini

  This week I decided to add a new element to a javascript array by copying a similar one from a previous line; unfortunately I forgot to remove the comma so the end result was something like var a = [1, 2, 3,]. The code went live late Friday afternoon just before everyone left for the week-end, and it completely broke everything in Internet Explorer 7 (and lower I assume) since it's such a great browser. Since there was no one to read emails (week-end) it went unnoticed for quite a while, and I really don't want something like this to happen again (especially in my code).. This is not the first of weird IE7 problems; I was wondering if there was a way to automatically test key pages looking for javascript or css errors, or really anything that IE8 would output in its new console in development tools. If there isn't, what do you usually do? You test the website after every change with all the browsers you support? (Something I'll do from now, at least for IE, if there is no way to run automated tests)

• Implementing a configurable factory

  - by Decko

  I'm having difficulties finding out how to implement a 'configurable' behavior in a factory class in PHP. I've got at class, which takes another class as an argument in its constructor. The argument class could take a number of arguments in its constructor. An instance of my main class could look something like this $instance = new MyClass(new OtherClass(20, true)); $instance2 = new MyClass(new DifferentClass('test')); This is rather clumsy and has a number of problems and therefore I would like to move this into a factory class. The problem is that this factory somehow needs to know how to instantiate the argument class, as this class can have any number of arguments in the constructor. Preferably I would like to be able to do something like this $instance = Factory::build('OtherClass'); $instance2 = Factory::build('DifferentClass'); And let the factory retrieve the arguments from a configuration array or similar. Is there a proper solution to this problem?

• Beagleboard: How do I send/receive data to/from the DSP?

  - by snakile

  I have a beagleboard with TMS320C64x+ DSP. I'm working on an image processing beagleboard application. Here's how it's going to work: The ARM reads an image from a file and put the image in a 2D array. The arm sends the matrix to the DSP. The DSP receives the matrix. The DSP performs the image processing algorithm on the received matrix (the algorithm code uses about 5MB of dynamically allocated memory). The DSP sends the processed image (matrix) to the ARM. The arm received the matrix. The arm saved the processed image to a file. I'v already written the code for steps 1,3,5. What is the easiest way to do steps 3+4 (sending the data)? Code examples are welcome.

• Pull datasets from DB and manipulate into separate arrays

• Fade between looped background images using jQuery

  - by da5id

  I'm trying to get the background image of a legacy div (by which I mean it already has a background image, which I cannot control & thus have to initially over-write) to smoothly fade between new images indefinitely. Here's what I have so far: var images = [ "/images/home/19041085158.jpg", "/images/home/19041085513.jpg", "/images/home/19041085612.jpg" ]; var counter = 0; setInterval(function() { $(".home_banner").css('backgroundImage', 'url("'+images[counter]+'")'); counter++; if (counter == images.length) { counter = 0; } }, 2000); Trouble is, it's not smooth (I'm aiming for something like the innerfade plugin). EDIT: question originally said "and it's not indefinite (it only runs once through the array).", but Mario corrected my stupid naming error. EDIT2: I'm now using Reigel's answer (see below), which works perfectly, but I still can't find any way to fade between the images smoothly. All help greatfully appreciated :)
