• Reading int from a hidden field in .aspx

  - by vikp

  Hi, I'm struggling to read an int from the hidden field on aspx page. <input type = "hidden" id = "myIntegerId" name = "integerId" value= "<%: Model.MyObjectId %>" runat = "server" /> The value is definately on the form, I can see it in the debugger and print it with <%: % When I read the form values in the controller, instead of an int I recieve a following string: <%: Model.MyObjectId % I have tried casting data in the hidden field to string and calling ToString() method on that field, neither has worked. The data is submitted using the post event. I have a feeling that I'm missing something very basic... Any help is greately appreciated. Thanks

• .htaccess newb - RewriteRule not matching 2nd rule, why?

  - by jyoseph

  I am currently migrating from isapi_rewrite to .htaccess. I'm having some difficulty and I think it's something basic, but I'm not terribly familiar with .htaccess. I have the two rules like so: RewriteRule ^testing/ /test/index.html?test=1 [NC] RewriteRule ^testing/foo-bar/ /test/index.html?test=2 [NC] Yet the second rule never matches. If I go to http://mydomain.com/testing/foo-bar/ then I will only see the first rule. Why is that? And can it be easily fixed? I have many rules (outputted from the database to write the .htaccess file )and ordering them in a particular order isn't really possible.

• Jquery javascript - How can I let users 'undo' their modifications?

  - by Bill Zimmerman

  Hi, i have a basic jquery app that allows a user to edit and manipulate some lists on a page. What I would like to do is have a button 'restore original list' that the user can press to undo his modifications. What is the best way to do this? I was thinking of just copying the DOM from the list down, and pasting it in a hidden element someplace else on the page. Is this the best way to do this? I also noticed that jquery has a .data() function which I could use if I converted the data to an array and stored it this way. What are the advantages and disadvantages? Also, I'm open to any suggestions people have if there is some method I haven't thought of. Thanks for your help!

• Starting Frame-By-Frame Animation

  - by OceanBlue

  Hi, I have a basic question about starting a frame-by-frame animation. When I call the AnimationDrawable.start() method from my code directly, it doesn't seem to work. public void onCreate(Bundle savedInstanceState) { ... mAnimation.start(); ... } But if I put this line inside the onClick() callback method of a button, pressing the buton starts the animation. Why doesn't this line work in the code? Thanks!

• Java: JPA classes, refactoring from Date to DateTime

  - by bguiz

  With a table created using this SQL Create Table X ( ID varchar(4) Not Null, XDATE date ); and an entity class defined like so @Entity @Table(name = "X") public class X implements Serializable { @Id @Basic(optional = false) @Column(name = "ID", nullable = false, length = 4) private String id; @Column(name = "XDATE") @Temporal(TemporalType.DATE) private Date xDate; //java.util.Date ... } With the above, I can use JPA to achieve object relational mapping. However, the xDate attribute can only store dates, e.g. dd/MM/yyyy. How do I refactor the above to store a full date object using just one field, i.e. dd/MM/yyyy HH24:mm?

• Sending JSON(jQuery) to PHP and decoding it

  - by dscher

  I can't for the life of me figure out what I'm doing wrong. It seems like it should be simple because I can't find anyone else with this issue but I can't figure out to send basic data via javascript(jQuery) to PHP and decode it. For the sake of simplicity, this is what I have: JAVASCRIPT var json_data = { "name" : "john doe" }; $.ajax({ type: "POST", url: "../bin/process.php", dataType: "json", data: json_data }); and my PHP FILE $arr = json_decode("json_data", true); $fp = fopen('data.txt', "w"); fwrite($fp, $arr['name']); fclose($fp); The file I'm writing ends up with nothing in it. If I do an: fwrite($fp, 'test'); I get a file with the word test in it but no matter what I do I don't get the json data I sent. Can someone please share a thorough example of A to Z. Thanks for any help.

• How should I handle searching through byte arrays in Java?

  - by Zombies

  Preliminary: I am writting my own httpclient in Java. I am trying to parse out the contents of chunked encoding. Here is my dilema: Since I am trying to parse out chunked http transfer encoding with a gzip payload there is a mix of ascii and binary. I can't just take the http resp content and convert it to a string and make use of StringUtils since the binary data can easily contain nil characters. So what I need to do is some basic things for parsing out each chunk and its chunk length (as per chunked transfer/HTTP/1.1 spec). Are there any helpful ways of searching through byte arrays of binary/part ascii data for certain patterns (like a CR LF) (instead of just a single byte) ? Or must I write the for loops for this?

• Book recommendation for a Ruby dev learning Java

  - by cpjolicoeur

  I've been a Ruby developer for the past 4-5 years, and prior to that coded in Perl and a language called ProvideX for years. As hard as it may seem, I've never written a Java application short of the basic Hello World app probably a decade ago. I'm beginning to start doing some Android development to port some iPhone applications we did for a client over to the Android platform. As such, I'm wondering what the best reference book I can buy is to get up to speed quickly with the features (and peculiarities) of Java. There are numerous "Learn Ruby for Java programmers" out there, but not really any reference books for going the otherway of Ruby-to-Java. I'm looking for something preferably like the "Learn Perl the Hard Way" book. I know how to code, I just need a reference on learning the proper mechanics of Java after having done Ruby (and a bit of Obj-C) work exclusively for the past few years.

• Simple WCF question.

  - by bearrito

  So I am learning WCF and I have run across an issue that I believe has to do with Instance Control/State but I am not sure. Workflow is as follows, Basic client/server paradigm. The client calls a Method RetrieveBusinessObjects(criteria) and the server calls the datalayer and then puts them in an IList on the server side. It does not return this list to the calling Client. The client would then call a method say DisplayBusinessObjects() which would retrieve the IList from the Server, serialize them, bring them across the wire and display them. If i try this using the WCFTestClient it works. If I run it from an actual client then I get back an BusinessObject[] of size 0. Which to me indicates I had no objects to return. Is that a state mgmt issue or am I missing something?

• Assembly Programming on Mac

  - by ida

  I am on a Mac with Snow Leopard (10.6.3). I hear that the assembly language I work with has to be valid with the chipset that you use. I am completely new to this I have a basic background in C and Objective-C programming and an almost strong background in PHP. I have always wanted to see what assembly is all about. The tutorial I'll be looking at is by VTC [link]. What I want to know is: are the tutorials that I'm about to do compatible with the assembly version on the Mac that I have? Sorry I am completely new to this language although I do recall studying some of it way, way back in the day. I do have xcode and what I'm wondering is what kind of document would I open in xcode to work with assembly and does the Mac have a built in hex editor (when it comes time to needing it)? thanks

• Drawing Sprites for iOS games on iPad

  - by TheGamingArt

  So, I'm quite new and confused on the way to tackle creating sprites/sprite sheets for iOS games. I own the full CS5 sweet and have been told that fireworks is the best way to go for creating these (although I don't have the slightest idea in how yet and would love some tutorials/books specifying sprite sheet creation). My thoughts directed me towards tablet drawing, as I am awful at drawing with a mouse and/or tablet without a screen on it (such as a basic wacom). I was thinking about getting an iPad, as this would provide me with an iPad for testing purposes and a tablet. Does anyone know if it's possible (or even a good idea) to draw out your sprites on the iPad. Is it possible to export them out into Fireworks and such?

• Simply display RSS feed in/on aspx page

  - by Louis van Tonder

  Maybe I am being a n00b here, but for the life of me, I cant find a simple drop in type solution for displaying an rss feed inside an aspx page? I am looking for a simple solution, as when Firefox gets pointed to an rss feed, it just plainly displays it, no thrills, no fuss. I don't want to get into the xml and format it extensively. I just want a basic feed, will style it with font and a:styles. Thats it. Any ideas? EDIT: I am attempting to show a worpress "feed" inside an aspx page...

• Caurina Tweener and Alpha

  - by Jk_

  Hi guys, Usually I work with TweenLite but I had to modify the code of someone else who worked with Caurina Tweener. I have a basic problem with it! On my scene, I have a simple movie clip filled with black. Into this movieclip a bitmap file (jpg). When I make a tween on the alpha of my mc, it seems that there is a delay (in the alpha) between this the black background and the image. Tweener.addTween(thisMc, { _autoAlpha:0, time:1 } ); I'm sure there is an easy way to avoid this problem but I can't find it out! Cheers, Jk_

• iphone refresh images UIImageView

  - by Rick

  I have a rather basic question. I have several(5) UIImageView images on my screen. When I click a button, I want to change each image to something else. I also want to play a sound as each image is changed. So I basically want a clicking sound as each image changes. The problem is, for some reason if I have say 5 images, the sound gets played 5 times first and then the images change. It's like the images only refresh when control goes back to the user for input. How can I "force" it to refresh the images as soon as i tell it what image to display? I'm new to the iphone/macworld, so go easy on me :-) Rick

• Manipulating source packages from Hackage how to easy deploy to several windowsboxes?

  - by Jonke

  Recently when I have found good sources packages for ghc 6.12/6.10 on Hackage I've been forced to do some minor or major changes to the cabal files to make those packages to work under windows. Besides to fork and merge my fixes with github, what seems to be the best way/ good enough practice to take these modified builds to a couple of other windows boxes that only has a basic haskell platform installed? I should prefer if I somehow could work with the cabal-install because that is what one normally use. Should one put the modfied build dirs on a shared/networked dir and mount from the targeted windows box? Say something like this: on machine prepare cabal fetch foo cabal unpack foo cd foo edit .cabal and .hs cabal configure cabal build On machine useanddevelopnormal cd machinepreparemount cd foo cabal install

• iphone: Accessing Code for Elements Created in Interface Builder

  - by user362685

  I am attempting to create a basic tab-bar application using interface builder. I create a new project in Xcode selecting tab bar application. My question is how can I access the code that instantiates and pushes each of the views when the tab bar buttons are pressed? I would imagine that would be done by the tab bar controller, however when I write the class file from interface builder (filewrite class files), it just creates a blank generic TabBarController.h/TabBarController.m without the methods for pushing each of the views associated with the tab bar elements. I ask this because I would like to pass each view controller a reference to the data model when they are instantiated. Any help would be greatly appreciated, thanks.

• Ajax routes in Rails 3

  - by Jatin

  In my Rails 2.3 application, the following routes were working properly map.ajax 'ajax', :controller => 'widgetresponse_controller' , :action => 'getWidgetJson' When I migrated to Rails 3, I tried a number of new routes, to get this working but none of them worked. 1. match 'ajax' => 'widgetresponse#getWidgetJson', :as => :ajax 2. match 'ajax' => 'widgetresponse_controller#getWidgetJson', :as => :ajax 3. get 'widgetresponse/getWidgetJson', :as => :ajax 4. get 'widgetresponse/getWidgetJson' Its a very basic question to ask, but I don't know what I am doing wrong.

• Can run Javascript but not jQuery?

  - by blazonix

  I'm running into a strange problem - I tried running a basic function in JS and jQuery, and while the former worked, the latter didn't. JS - okay alert('Works'); jQuery - not okay $(document).ready({ alert('Works'); }); Here's some facts: My references to the jQuery library are correct (And pretty sure my Internet connection is steady :) I'm using a CDN - CloudFlare to be exact, but I've switched development mode on and Rocket Loader off - so all the code I've uploaded to the server is WYSIWYG (CloudFlare adds some stuff in the tags if you leave Rocket Loader on. I tried running the alert code in the head section, and elsewhere in the body tags, to no avail. What could have possibly gone wrong?

• How should it work if I want a page to have a theme-roller (more or less like the jQuery themeroller

  - by DanC

  The basic idea is to create a page that gives the user the ability to choose a skin or theme from a menu. When the user selects the desired skin/theme, it should be applied to the page, just like the jquery ui theme roller page. So, to be more precise, what I am trying to know is how to apply dynamically the style to a page - how to load the css and so forth. On the jquery ui theme roller, is there any javascript triggered after the new set of styles is loaded? (for js positioning or sizing?) (The answer may be simple as "just create a new style element and set its src"...) Just to be clear, I don't need the option to let users customize the UI, I want them just to be able to pick from a few pre set styles. Thanks!

• Optimizing MySQL statement with lot of count(row) an sum(row+row2)...

  - by Zombies

  I need to use InnoDB storage engine on a table with about 1mil or so records in it at any given time. It has records being inserted to it at a very fast rate, which are then dropped within a few days, maybe a week. The ping table has about a million rows, whereas the website table only about 10,000. My statement is this: select url from website ws, ping pi where ws.idproxy = pi.idproxy and pi.entrytime > curdate() - 3 and contentping+tcpping is not null group by url having sum(contentping+tcpping)/(count(*)-count(errortype)) < 500 and count(*) > 3 and count(errortype)/count(*) < .15 order by sum(contentping+tcpping)/(count(*)-count(errortype)) asc; I added an index on entrytime, yet no dice. Can anyone throw me a bone as to what I should consider to look into for basic optimization of this query. The result set is only like 200 rows, so I'm not getting killed there.

• How can Excel 2007 / 2010 consume a REST web service?

  - by jallen

  What options exist to consume a REST web service from within Excel 2007 / 2010? I can use XML Maps to consume a basic XML list, but that doesn't let me build a dynamic URL (so I could include parameters). For example, I can add an XML Map to Excel for http://machine/service/level/5 and display the values in the workbook just fine - no problem there. The real question is, how can I dynamically change the /5 part of the URL to come from another cell in excel? That way I can have a couple of cells that have the options (what ID, what name, etc.) and whenever those values change (ideally) a new dynamic URL would be constructed and the XML map would be refreshed. Is such a thing possible? Does anyone else have a better way to take some parameters, call a web service (REST or SOAP, I'm not picky) and shove the results back into excel for further manipulation?

• dojo.gfx matrix transformation

  - by Linus

  Matrix transformations has got my head spinning. I've got a dojox.gfx.group which I want to be draggable with Mover and then be able to rotate it around a certain point on the surface. My basic code looks like this: this.m = dojox.gfx.matrix, . . . updateMatrix: function(){ var mtx = this.group._getRealMatrix(); var trans_m = this.m.translate(mtx.dx, mtx.dy); this.group.setTransform([this.m.rotateAt(this.rotation, 0, 0), trans_m]); } The rotation point is at (0,0) just to keep things simple. I don't seem to understand how the group is being rotated. Any reference to simplistic tutorial on matrix transformations would also help. The ones I've checked out haven't help too much.

• problem adding a where clause to a T-sql LEFT OUTER JOIN query

  - by Nickson

  SELECT TOP (100) PERCENT dbo.EmployeeInfo.id, MIN(dbo.EmployeeInfo.EmpNo) AS EmpNo, SUM(dbo.LeaveApplications.DaysAuthorised) AS DaysTaken FROM dbo.EmployeeInfo LEFT OUTER JOIN dbo.LeaveApplications ON dbo.EmployeeInfo.id = dbo.LeaveApplications.EmployeeID WHERE (YEAR(dbo.LeaveApplications.ApplicationDate) = YEAR(GETDATE())) GROUP BY dbo.EmployeeInfo.id, dbo.EmployeeMaster.EmpNo ORDER BY DaysTaken DESC The basic functionality i want is to retrieve all records in table dbo.EmployeeInfo irrespective of whether a corresponding record exists in table dbo.LeaveApplications. If a row in EmployeeInfo has no related row in LeaveApplications, i want to return its SUM(dbo.LeaveApplications.DaysAuthorised) AS DaysTaken column as NULL or may be even put a 0. With the above query, if i remove the where condition, am able to achieve what i want, but problem is i also want to return related rows from LeaveApplication only if ApplicationDate is in the current year. Now with the where condition added, am only able to get rows from EmployeeInfo only if they have corresponding rows in LeaveApplications yet i just wanted rows all in EmployeeInfo
