• html5 video player with simplest controls (only play and paus)

  - by mathiregister

  hi guys, somehow there are really little tutorials out there for html5 video and audio playback. I simply want to embed video and audio files with customized controls. However the controls should be farely simple. I only need a play-button. If clicked, play gets replaced by pause. that's all! however i even don't know how to embed/display a video without "preload controls". Somehow if i only set (without preload controls) Firefox even don't shows anything. Chrome does show a black window. I would love to be able to use jquery to control the video play and pause button. Maybe you have some little start-approach for me! thank you very much!

• When loading shopping cart in Magento with a new Payment module, I get an error I haven't been able

  - by Joseph

  I am trying to add a new payment module into Magento. However, even after commenting out the vast majority of the code, I still get the following error: Fatal error: Call to a member function isAvailable() on a non-object in /var/www/html/app/code/core/Mage/Payment/Helper/Data.php on line 71 I am using Magento 1.4.0.1, and have disabled the cache. I even emptied the cache several times just in case. The only code currently not commented out is based on the tutorials here and here. The error occurs when the cart is loaded either from the administration area or the front end. Is there anyone out there that has run into a similar issue? I would post code, but I am not sure what needs to be posted. Thanks for the assistance.

• Which faces technology for use with GlassFish 2.1 and NetBeans 6.7?

  - by SteJav

  I'm running GlassFish 2.1 and using NetBeans 6.7. I'd like to create a web interface to my data using JSF 1.2. Trouble is, I'm not sure which 'faces' technology to learn (that includes some good documentation). JBoss/RichFaces seem pretty good on documentation, but I'm using GlassFish. Any thoughts? The choices appear overwhelming: Tomahawk Tobago Trinidad ICEfaces RCFaces Netadvantage WebGalileoFaces QuipuKit BluePrints Woodstock JBoss RichFaces Ajax4jsf ILOG Oracle ADF G4JSF Simplica Backbase jenia4faces VisualWebPack DynaFaces IBM Impl Dinamica Mojarra PrimeFaces jQuery OpenFaces ZK ExtJS Anybody had any experience with any of the above and found the documentation to be clear to a beginner? Being a JSF/Web beginner, I tried some ICEFaces, Mojarra tutorials and had a go at getting RichFaces working with NBeans and GlassFish, but no luck. Lots of XML complaints. I'm clearly missing some huge chunks of configuration, but I can't find any documentation to help me. Any suggestions would be much appreciated :-)

• Getting specific values with regex

  - by David

  I need to knowingly isolate each row of the vCard and get its value. For instance, I want to get "5555" from X-CUSTOMFIELD. So far, my thoughts are: "X-CUSTOMFIELD;\d+" I have been looking at some tutorials and I am a little confused with what function to use? What would my regex above return? Would it give me the whole line or just the numerical part (5555)? I was thinking I i get the whole row, I can use substring to get the digits? BEGIN:VCARD VERSION:2.1 N:Last;First; FN:First Last TEL;HOME;VOICE:111111 TEL;MOBILE;VOICE:222222 X-CUSTOMFIELD;5555 END:VCARD

• load search results into a div jquery and rails

  - by odpogn

  In my rails app I have a search bar where users can search other users. Currently when a User submits the search from, they're redirected to a "results" page. I want to load those results in a div on the same page.. I was able to do this with my websites navigation links, but I'm pretty new to jQuery and rails and can't figure this one out... my jQuery corresponding to my navigation links: $(function() { $('#links a').live('click', function() { $('#pages').load(this.href).fadeIn('slow'); return false; }); }); my attempt to do the same with my search function... $(function() { $('#search').submit(function() { $('#pages').load(this.href).fadeIn('slow'); }); }); any help would be much appreciated~ along with some useful jQuery tutorials for a newbie!!

• Get a single element with PHP and XPath

  - by daliz

  Lots of tutorials around the net but none of them can explain me this: How do I select a single element (in a table, for example), having its absolute XPath? Example: I have this: /html/body/table/tbody/tr[2]/td[2]/table/tbody/tr/td/table[3]/tbody/tr/td/table/tbody/tr[3]/td/table/tbody/tr[4]/td[5]/span What's that PHP function to get the text of that element?! Really I could not find an answer. Found lots of guides and hints to get all the elements of the table, all the buttons of a form, etc, but not what I need. Thank you.

  - by spderosso

  I want to create a web app that will use wicket, hibernate and spring frameworks. My IDE of choice is Eclipse, I am using maven for the .war generation and I am running Mac OS. What steps should I follow to correctly install and configure all the tools so as to have a project running that relies on these 3 frameworks. I was able to successfully set up wicket but I am having trouble for setting up hibernate and spring. I went through multiple tutorials but I still couldn't find the solution. Thanks!

• Getting search results from Twitter in php

  - by Mark Mayo

  I'm attempting to put together a little mashup with some twitter APIs. However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken. Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term. Followed the tutorial to the letter at http://www.reynoldsftw.com/2009/02/using-jquery-php-ajax-with-the-twitter-api/ and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there. I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now.

• iPhone - Landscape Only App

  - by Robert

  Hello all! I am trying to make an app that will only be viewed in Landscape. I have looked up some tutorials (albeit older ones) and have done the following: -set up the info.plist to include a key for uiinterfaceorientation -in the main view controller I have set the frame to be 480 x 320 Now, the first screen loads up ok. Everything is where it should be and whatnot. However, if I click a button that is set to present a modal view controller nothing happens. Everything is linked and coded correctly but nothing happens when I press the button. Am I doing something wrong with trying to force landscape? At it's basic, this question is a how do you effectively make an app that will only be in landscape mode? Thanks for any help.

• Building a service for a Drupal site to duplicate a node to another Drupal site in a multi-site setu

  - by EricP

  I'm trying to set up one of my Drupal sites to push a node to another Drupal site in a multi-site configuration. It looks like I need to do this with services somehow, but I can't find any tutorials out there and I need at least to be pointed in the right direction. What I believe I need is set up Services on the receiving site to accept a call from the sending site which will be sending the node object via Json or serialized PHP using a Key that was set up on the receiving site. Can anyone show me an example of this working or give me some insight? thanks

• Dynamically load _gallery_ (not album) in SlideShowPro using SWFObject

  - by bccarlso

  Hi all. I have been successful in dynamically loading an album in SSP before, but using SSP Standalone. I did it like this: var flashvars = { xmlFilePath: "http://site.com/ssp_director/images.php?album=5" } What I'm looking to do now, though, is dynamically load a gallery when the page loads, using text entered in the javascript, or flashvars I'd assume. I'm using ActionScript 3 with this, so I'm not sure if I have to do something to the SSP instance in Flash. I'm not very good with AS3, so following advice or tutorials is about all I can muster. I'm also using SSP Director, so my gallery XML URLs would be similar to above in the example code. I'd be elated if this is possible, otherwise I will have to find an alternative solution. Thanks so much for help!

• Should a service layer return view models for an MVC application?

  - by erg39

  Say you have an ASP.NET MVC project and are using a service layer, such as in this contact manager tutorial on the asp.net site: http://www.asp.net/mvc/tutorials/iteration-4-make-the-application-loosely-coupled-cs If you have viewmodels for your views, is the service layer the appropriate place to provide each viewmodel? For instance, in the service layer code sample there is a method public IEnumerable<Contact> ListContacts() { return _repository.ListContacts(); } If instead you wanted a IEnumerable, should it go in the service layer, or is there somewhere else that is the "correct" place? Perhaps more appropriately, if you have a separate viewmodel for each view associated with ContactController, should ContactManagerService have a separate method to return each viewmodel?

• I would like to learn C++, what is the first step ?

  - by Cesar

  My actual experience comes from PHP and Delphi(Borland) and recently also from Obj-C (iPhone sdk). In the past I also used Java, Python, VB 6 and some other scripting language. I would like to learn C++ because i need a standard tool for write compiled applications with good performance but i have no idea about witch environment i have to choose (Ex: Borland, Microsoft, Eclipse+MinGW, ...). Based those parameters: Most useful more opensource project or work requests Most standard not a proprietary versions Biggest community documentation, manuals, tutorials, forums... Better IDE add-ons, highlight, debug, cross platform, autocomplete... Easy setup A simple setup, to focus on learning the basics Actually I'm on OSX but I can use a VM if needed. Advices about tutorial or books are welcome. I hope it's not too generic as question.

• Implementing a recursive menu system a'la Joomla in CodeIgniter

  - by pettersolberg

  Hi I have some sites powered by Joomla, but with my current assignment I wanted to try something new and created with CodeIgniter a really basic CMS (just to suit my client's needs). Everything works fine except menus - multilevel menus like in Joomla, Drupal etc. with items and subitems... My question is: do you know of any tutorials or texts abut implementing such a structure. I've tried the recursion thinggy with while getting children's IDs move downwards from the parent while searching for the currently displayed item's ID. I've tried also the Drupalish way with having a path parameter enclosing ID's all the way from top to bottom '1/23/123/3'. But all in all it was just too chaotic - code something, try it out. If you have some idea on this topic - thanks in advice.

• How do you check individual SqlCommands ran during a SqlTransactions to see if they will run?

  - by Sam F

  I've been reading up on SqlTransactions and have found a great load of examples like: http://www.devhood.com/tutorials/tutorial_details.aspx?tutorial_id=451 The problem is, when I do a BeginTransaction() (Execute all the commands) and then Commit() at the end all the commands I execute get run and the ones with syntax errors or other errors just get skipped. This is where I would also like to run a roll back, not skip over them. I found a few articles on the subject but they were not very helpful and purely in SQL. Is there any way to find out if one of the ExecuteNonQuery()'s failed before the commit and not just skipped? Thanks.

• Read XML from an XDocument with silverlight

  Hi I have managed to load an XDocument with xml data from this link http://go.yr.no/go/e/main/http://www.yr.no/place/Norway/Telemark/Sauherad/Gvarv/forecast.xml. I am using C# and .Net in Blend and producing a web app (ie some of the normal .Net functions is not included in the silverlight plugin). I have researched this a lot but can not figure out: how to put the "text" in the link node in a string variable and how to all put the "-11" from ? in a array and link it to the "time from"? I think i have to use LINQ, but the stuff on MSDN and other tutorials is confusing and to general. huge thank in advance Regards Arnt I am sorry to ask such novice questions, but i have searched a lot. Also please excuse the typos, English is not my first language. Huge thank in advance Arnt

• Getting print data - Windows (Redmon)

  - by Anurag Ramdasan

  I am trying to develop an app to retrieve print data, edit its content and then print the data. I am using RedMon for that purpose. But all the tutorials I have seen online as of now relates to storing the data into a PDF using RedMon. I want to be able to configure RedMon on a windows platform such that it writes the entire print data(the data that is bound to appear on the printing paper) as it is into a .txt file or maybe provide directly as an input to the java app that I have made. I have been unsuccessful in finding a solution for this till now. Is this achievable?

• Scraping html WITHOUT uniquie identifiers using python

  - by Nicholas Law

  I would like to design an algorithm using python that scrapes thousands of pages like this one and this one, gathers all the data and inserts it into a MySQL database. The script will be run on a weekly or bi-weekly basis to update the database of any new information added to each individual page. Ideally I would like a scraper that is easy to work with for table structured data but also data that does not have unique identifiers (ie. id and classes attributes). Which scraper add-on should I use? BeautifulSoup, Scrapy or Mechanize? Are there any particular tutorials/books I should be looking at for this desired result? In the long-run I will be implementing a mobile app that works with all this data through querying the database.

• Compiling error with API 10

  - by Suhel De Corser

  I was following the basic tutorials on developers.android.com and came by creating the activity named DisplayMessageActivity. It is a blank activity with all the specifications given as shown in the tutorial. FYI, I am using Min SDK = API 8, Target SDK = API 16, Compile with = API 10 The next thing is that there are two errors: "The method getActionBar() is undefined for the type DisplayMessageActivity "home cannot be resolved or is not a field" I tried changing the API to 14 which called for another problem, it wants the minimum API to be 11. That solves these problems, but the main problem is so many devices still use Gingerbread or maybe FroYo. Can't I write for them? Do I have to go higher? How to write for them?
