  • Autoplay an Audio File on Mobile Safari

    - by phantomdata
    Hey guys, I've got a little system dashboard web app that I've written, replete with alarm notifications. I've had it working for quite some time on mobile safari, but recently wanted to add audio to the alarm notifications to allow me to easily know when there are alarms and I'm not looking directly at the display. The alarm notifications are populated through a (relatively) constantly polling ajax request that pulls in and displays an alarm banner if alarms are present. I wanted to add an auto-playing 'alarm' sound as well, but no dice for Safari Mobile. I've tried using HTML5 and embedded objects with no avail. The Apple documentation does state that you can't auto-play an audio file and it must be activated through user action to conserve bandwidth. Has anyone found a way around this in a WLAN setting?

  • Best Template Engine for ASP.NET MVC

    - by OnesimusUnbound
    I am exploring ASP.NET MVC and I wanted to add jQuery to make the site interactive. I used StringTemplate, ported to .Net, as my template engine to generate html and to send JSON. However, when I view the page, I could not see it. After debugging, I've realized that the $ is used by the StringTemplate to access property, etc and jQuery uses it too to manipulate the DOM. Gee, I've looked on other template engines and most of them uses the dollar sign :(. Any alternative template engine for ASP.Net MVC? I wanted to retain jQuery because MSFT announced that it will used in the Visual Studio (2008?) Thanks in Advance :)

  • Changing property type in class that implements interface with object type property.

    - by used2could
    I know the title is a bit confusing but bare with me. (I'm up for suggestions on a new title lol) I'm writing a TemplateEngine that will allow me to use my own markup in text based files. I'm wanting to add controls as plugins as the application matures. Currently i've got a structure like the following: interface IControl string Id object Value class Label : IControl string Id string Value class Repeater : IControl string Id List<IControl> Value Now you'll see the strange part right away in the Repeater class with the Value property. I was hoping that having the Value type as object in the interface would allow me the flexibility to expand the controls as i go along. The compiler doesn't like this and for good reason i guess. Does anyone have any suggestions how to accomplish this? Note: Please don't go into suggesting things like use Spark View Engine for templating. There is a reason i'm creating extra work for myself.

  • Should I use uint in C# for values that can't be negative?

    - by Johannes Rössel
    I have just tried implementing a class where numerous length/count properties, etc. are uint instead of int. However, while doing so I noticed that it's actually painful to do so, like as if no one actually wants to do that. Nearly everything that hands out an integral type returns an int, therefore requiring casts in several points. I wanted to construct a StringBuffer with its buffer length defaulted to one of the fields in that class. Requires a cast too. So I wondered whether I should just revert to int here. I'm certainly not using the entire range anyway. I just thought since what I'm dealing with there simply can't be negative (if it was, it'd be an error) it'd be a nice idea to actually use uint. P.S.: I saw this question and this at least explains why the framework itself always uses int but even in own code it's actually cumbersome to stick to uint which makes me think it apparently isn't really wanted.

  • RESTful services and update operations

    - by Igor Brejc
    I know REST is meant to be resource-oriented, which roughly translates to CRUD operations on these resources using standard HTTP methods. But what I just wanted to update a part of a resource? For example, let's say I have Payment resource and I wanted to mark its status as "paid". I don't want to POST the whole Payment object through HTTP (sometimes I don't even have all the data). What would be the RESTful way of doing this? I've seen that Twitter uses the following approach for updating Twitter statuses: http://api.twitter.com/1/statuses/update.xml?status=playing with cURL and the Twitter API Is this approach in "the spirit" of REST? UPDATE: PUT - POST Some links I found in the meantime: PUT or POST: The REST of the Story PUT is not UPDATE PATCH Method for HTTP

  • difference in logging mechanism: API and application(python)

    - by zubin71
    I am currently writing an API and an application which uses the API. I have gotten suggestions from people stating that I should perform logging using handlers in the application and use a "logger" object for logging from the API. In light of the advice I received above, is the following implementation correct? class test: def __init__(self, verbose): self.logger = logging.getLogger("test") self.logger.setLevel(verbose) def do_something(self): # do something self.logger.log("something") # by doing this i get the error message "No handlers could be found for logger "test" The implementation i had in mind was as follows: #!/usr/bin/python """ .... .... create a logger with a handler .... .... """ myobject = test() try: myobject.do_something() except SomeError: logger.log("cant do something") Id like to get my basics strong, id be grateful for any help and suggestions for code you might recommend I look up. Thnkx!

  • Best solution for managing navigation (and marking currently active item) in CakePHP

    - by Nathan
    So I have been looking around for a couple hours for a solid solution to handling site navigation in CakePHP. Over the course of a dozen projects, I have rigged together something that works for each one, but what I'm looking for is ideally a CakePHP plugin that handles the following: Navigation Model Component for handing off to the view Element View Helper for displaying the navigation (with control over sublevels displayed and automatically determining the "active" item based on URL and/or controller/model/slug Admin pages for managing a tree of navigation Any suggestions for an all-in-one solution or even the individual components would be very appreciated! Or even suggestions on how you have handled it in the past

  • Learn Obj-C Memory Management

    - by Joshua Brickner
    I come from a web development background. I'm good at XHTML, CSS, JavaScript, PHP and MySQL, because I use all of those technologies at my day job. Recently I've been tinkering with Obj-C in Xcode in the evenings and on weekends. I've written code for both the iPhone and Mac OS X, but I can't wrap my head around the practicalities of memory management. I understand the high-level concepts but am unclear how that plays out in implementation. Web developers typically don't have to worry about these sorts of things, so it is pretty new to me. I've tried adding memory management to my projects, but things usually end up crashing. Any suggestions of how to learn? Any suggestions are appreciated.

  • Checkstyle for C#?

    - by PSU_Kardi
    I'm looking to find something along the lines of Checkstyle for Visual Studio. I've recently started a new gig doing .NET work and realized that coding standards here are a bit lacking. While I'm still a young guy and far from the most experienced developer I'm trying to lead by example and get things going in the right direction. I loved the ability to use Checkstyle with Eclipse and examine code before reviews so I'd like to do the same thing with Visual Studio. Anyone have any good suggestions? Another thing I'd be somewhat interested in is a plug-in for SVN that disallows check-in until the main coding standards are met. I do not want people checking in busted code that's going to wind up in a code review. Any suggestions at this point would be great.

  • Connection Strings between Web Application and SQL Server

    - by Raven Dreamer
    Greetings. I'm writing a web application that is supposed to connect to a SQL Server database; the connection is formed from the following database string: <add key="DatabaseConnectionString" value="server=DEVPC1\SQLEXPRESS;uid=USERID;pwd=PASSWORD;database=DATABASE"/> However, whenever I try and run the web application, I get a connection error, specifically: An error occurred attempting this login: Login failed for user 'USERID'. Any suggestions on how to go about debugging this? I'm not really familiar with SQL, so any suggestions would be greatly appreciated.

  • What should a conference newbie bring to make the most out of their first conference?

    - by skarnis
    I am planning to attend my first developer conference (Microsoft TechDays 2008 in Toronto). I have been looking around for suggestions so that I can prepare and make the most out of my first developer conference. Many articles make suggestions about asking questions, getting involved, being social. These are great! I am also wondering about physical items. I have seen many conference photos with most of the audience having their laptops. Are they just taking notes? Are they working on a problem during the session? Are these photos just during a break and everyone is catching up on blogs/email/outside contact? Thank you StackOverflow-ers (StackOverflow-ites?)

  • Does DataType DataAnnotation Check the Expression?

    - by Jason
    I am currently using DataAnnotations within my ASP.NET MVC website to ensure data is properly validated. One question I wanted to verify (I think I know the answer, but I can't find verification online) - does the DataType DataAnnotation perform regular expression checks to ensure that you have received a valid e-mail/phone/currency/etc? [Required(ErrorMessage = "Price required")] [DataType(DataType.Currency, ErrorMessage = "Not a valid price")] [Range(0, double.MaxValue, ErrorMessage = "Price must be greater than 0.")] public decimal Price { get; set; } I believe the answer is no (meaning I have to provide my own, custom, RegularExpressionAttribute), but I wanted to double check before I do that for various field types.

  • How do I dynamically name objects in Java?

    - by hatboysam
    Let's say I needed to make a series of String[] objects. I know that if i wanted to make a string array called "test" to hold 3 Strings I could do String[] test = new String[3]; But let's say I needed to make a series of these arrays and I wanted them to be named, 1,2, 3, 4, 5... etc. For however many I needed and I didn't know how many I'd need. How do I achieve a similar effect to this: for (int k=0; k=5; k++){ String[] k = new String[3]; } Which would created 5 string arrays named 1 through 5. Basically I want to be able to create array objects with a name detemined by some other function. Why can't I seem to do this? Am I just being stupid?

  • Xhtml instead of Php?

    - by ihaveitnow
    I want to develop a site that will allow be to publish information to users, and give them and opportunity to subscribe to a mailing list so they can be updated each time I make a change to the site. *Add new information, etc. I also would like for the users to be able to add comments about reviews posted, and give me suggestions...Things that will encourage user interaction I understand that this is possible with php... But I do not know php, and to learn and test it I apparently need a domain to begin with...etc. Is it possible that I use Xhtml/Html to get the same results? -- I know I can use the <a href="mailto:[email protected]"; subject="Email from Site user">Mail</a> but that would also leave my email open to spam...Any suggestions? And I do apologize if this question has been posted before, I did some research and found no such thing. All helpful responses are appreciated.

  • Print a JavaScript array to HTML, square brackets and quotation marks intact

    - by Mark Gia Bao Nguyen
    I'd like to set the attribute of an input form with an array of values (to use for autocomplete search). I have a JS array that looks a little something like this: var suggestions = ["value1", "value2", "value3"]; Using jQuery, I did this: $("#search-input").attr("data-source", suggestions); Desired output: <input type='search' data-source='["value1", "value2", "value3"]' /> Actual output: <input type='search' data-source='value1, value2, value3' /> This breaks the autocomplete as it requires an array (or at least something that looks like a JavaScript array).

  • SOAP - Why do I need to query for the values for an update?

    - by Phill Pafford
    I'm taking over a project and wanted to understand if this is common practice using SOAP. The process that is currently in place I have to query all the values before I do an update cause I need to pass back all the values that are not being updated. Does this sound right? Example Values: fname=phill lname=pafford address=123 main phone:222-555-1212 So if I just wanted to update the phone number I need to query for the record, get all the values and submit these values for an update. Example Update Values: fname=phill lname=pafford address=123 main phone:111-555-1212 I just want to know if this is common practice or should I change the functionality of this?
