  • CoreGraphics on iPhone. What is the proper way to load a PNG file with pre-multiplied alpha?

    - by dugla
    For my iPhone 3D apps I am currently using CoreGraphics to load png files that have pre-multiplied alpha. Here are the essentials: // load a 4-channel rgba png file with pre-multiplied alpha. CGContextRef context = CGBitmapContextCreate(data, width, height, 8, num_channels * width, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); // Draw the image into the context CGRect rect = CGRectMake(0, 0, width, height); CGContextDrawImage(context, rect, image); CGContextRelease(context); I then go on and use the data as a texture in OpenGL. My question: By specifying pre-multiplied alpha - kCGImageAlphaPremultipliedLast - am I - inadvertently - telling CoreGraphics to multiply the r g b channels by alpha or - what I have assumed - am I merely indicating that the format of the incoming image has pre-multiplied alpha? Thanks, Doug

  • WMD Markdown and server-side

    Hello, I work since 2 days on WMD & Markdown and i don't find THE solution for stock data with security. I would like users can post html/xml (with WMD) on my site. For the moment, I stock data in Markdown format but If I disabled JavaScript the user can push easy XSS. If I strip_tags or html_entities all data i loose the user html/xml . How can I do ? In my opinion I must html_entities just the code between pre /pre, but how?! my data is in Markdown. After, how I can do for forbid xss attributes : <img src="javascript:alert('xss');" /> Sorry for my rusty english. MaxoU

But i get Row Unavailable exception - is my approach wrong? any suggestions?

  • Rails routes creating additional info in URL

    - by Danny McClelland
    Hi Everyone, Say if I have a model called 'deliver' and I am using the default URL route of: # Install the default routes as the lowest priority. map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format' So the deliver URL would be: http://localhost:3000/deliver/123 What I am trying to work out, is how to use another field from the database alongside or instead of the ID. For example. If I have a field in the create view called 'deliveraddress', how do I put that into the routes? So I can have something link this: http://localhost:3000/deliver/deliveraddress Thanks, Danny

  • Generic Data Structure Description Language

    - by Jon Purdy
    I am wondering whether there exists any declarative language for arbitrarily describing the format and semantics of a data structure, that can be compiled to a specific implementation of that structure in any of a set of target languages. That is, something like a generic data definition language but geared toward describing arbitrary data structures such as vectors, lists, trees, etc., and the semantics of operations on those structures. I ask because I had an idea for a feasible implementation of this concept, and I'm just wondering whether it's worth it, and, consequently, whether it's been done before. Another, slightly more abstract question: is there any real difference between the normative specification of a data structure (what it does) and its implementation (how it does it)?

  • How do continuously update data to an asp page?

    - by Lori
    Hi, I have an asp page based on a very simple database. It references a single table of probably 30 records and maybe 12 data fields and everything works great as I am only uploading a new database every week or so. I have a special circumstance where I would like upload new data to the database and display automatically on the page every 20 to 30 seconds without the user having to refresh their screen. I would expect up to 1000 concurrent users accessing the data. I have been manually uploading the database via ftp, which will obviously not work on this timeline and would also run the risk of error pages as the database is being replaced. So, can anyone point me the right direction to setup this scenario? Other details that might be helpful: The database is an Access database (but I could change to another format if needed) Running on Windows platform hosted by an ISP, not my own server Thanks in advance for any help on this! Lori

  • Breaking changes in .NET 4.0

    - by Andrei Taptunov
    There is a lot of information about new features and classes in new 4.0 however there are also changes that may affect esixting applications, for example Timespan now implements IFormattable and old string.Format() with invalid options will throw exception instead of calling simple ToString(). However, CLR team provides a nice feature to enable behaviour from previous version with configuration setting - TimeSpan_LegacyFormatMode . CLR Inside Out Access to events inside the class where they are declared using += or -= will lead to call add/remove generated accessors that return void. Some code wan't even compile in 4.0. Chris Burrows Blog CAS is deprecated and to enable it one still need to use special setting in configuration - NetFx40_LegacySecurityPolicy So I wonder what are other changes and is it possible to find at least preliminary list of changes that will or may break existing functionality with release of .NET 4.0 ?

  • retrieve cobol s9(2) COMP onto C variable

    - by Pablo Cazallas
    Hi, I need to retrieve data from a COBOL variable of the type: "PIC S9(2) COMP" onto a C variable of the type "int". It's stored using two bytes of a string, so I receive it as a couple of chars. I know COBOL stores decimal data onto a "S9(2) COMP" in binary format, so It would be a great help letting me know any algorithm or way to convert it safely. Any kind of help & suggestion will be welcome. Thanks in advance and regards, Pablo.

  • Any collaborative tool/website to localize an Android app?

    - by Nicolas Raoul
    My open source Android application has internationalization done the Android way, with strings.xml files. The community has many people from many countries, and they are willing to contribute/improve translations using a collaborative website. There is Launchpad but it only supports the gettext format so we would have to use scripts, not very convenient. There is Crowdin but somehow this website seems dead, nearly no projects, and the download links do not work. Actually we started using Crowdin but all download links fail to give any strings.xml file back, see here. What website is convenient for translating open source Android applications?

  • Google Maps API Geocode gives error "Invalid label" in Firefox

    - by Bennystijn
    Today I struggled with the following: $.ajax({url:'http://maps.google.com/maps/api/geocode/jsonaddress=Karachi&sensor=false&output=json&callback=?', dataType: 'json', success: function(data){ //eval("("+data+")"); alert(data); } }); Firefox gives the error "Invalid Label" and Chrome "Uncaught SyntaxError: Unexpected token :". I found a lot of posts about this, and I tried all kinds of things like eval(), but also: $.getJSON('http://maps.google.com/maps/api/geocode/jsonaddress=Karachi&sensor=false&output=json&callback=?', function(data){ //eval("("+data+")"); alert(data); } ); Same result. Also, other json data works fine, for instance flickr ("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?). So it has something to do with the Google Maps API output i guess.. Thanks in advance.

  • html hyperlinks show URL in brackets in Entourage

    - by Rafe
    I have an email script written in .Net that sends html emails. The email uses normal html hyperlinks to insert a link in the email, like this: <a href="http://www.stackoverflow.com/">StackOverflow</a> The problem is that in Entourage, a hyperlink like this always shows up for me like this: StackOverflow < http://www.stackoverflow.com/ > How can I format the hyperlink in my email so that in Entourage the text "StackOverflow" is the actual hyperlink, and the URL is not displayed after the text? Is there an html meta tag that needs to be set? Do I have to set the content-type somewhere? Or is there a different html syntax on the hyperlink itself that I should use?

  • Regex for capturing numbered text list

    - by crunchyt
    I have a test list that I am trying to capture data from using a regex. Here is a sample of the text format: (1) this is a sample string /(2) something strange /(3) another bit of text /(4) the last one/ something!/ I have a Regex that currently captures this correctly, but I am having some difficulty with making it work under outlier conditions. Here is my regex /\(?\d\d?\)([^\)]+)(\/|\z)/ Unfortunately some of the data contains parentheses like this: (1) this is a sample string (1998-1999) /(2) something strange (blah) /(3) another bit of text /(4) the last one/ something!/ The substrings '(1998-1999)' and '(blah)' make it fail! Anyone care to have a crack at this one? Thank you :D

  • rendering JSON in GRAILS with part of the attributes of an object

    - by bsreekanth
    Hello, I am trying to build JSON from two fields. Say, I have a list of object(party), and I only need to pass 2 items as JSON pair. def list = getMyList() //it contains 2 party objects partyTo = array { for (i in list) { x partyId: i.id y partyName: i.toString() } } The JSON string is {"partyTo":[ {"partyId":12}, {"partyName":"Ar"}, {"partyId":9}, {"partyName":"Sr"} ] } when I extract it at the client, it is treated as 4 objects. I wanted as 2 objects, with the below format. {"partyTo":[ {"partyId":12 , "partyName":"Ar"}, {"partyId":9 , "partyName":"Sr"} ] } I'm getting 4 objects, probably because I use an array to build JSON. I'm new to groovy and JSON, so not sure about the right syntax combinations. Any help highly appreciated. thanks.

  • DIV Overlaying DIV, links in backmost DIV non-accessible

    - by Shawn
    I have a photoshop image that is 500x600 that I am using as a background image for the first div. The second div sits over top of the first div and is populated with images. The z-index of the first div is set to 100. The effect is the photoshop image sits over top of all of the smaller images. The photoshop image is a letter with the inner-content of it set to be transparent and the small images create the filling. Each of the small images however is a link, but none of the links are accessible. How can I remedy that? I would post the code here, but I have absolutely no clue how to format it. I quite simply do not understand typing a backtick followed by the tab key and then a dollar sign. All that ends up is I type a backtick here followed by a dollar sign in the Tags section below.

  • List of objects to JSON to Html Table?

    - by DaveDev
    If I have a list of objects IEnumerable<MyType> myTypes; Is it possible for me to return this to the client as JSON return Json(myTypes); and if so, is it possible for me to convert this (now JSON format) list to a when it gets to the client? Is there any jQuery plugin to do this? The thing is, there's loads of other stuff I need to send as JSON also, so generating a table with a PartialView and embedding that into the JSON is a extra complexity that I'd like to avoid. Thanks.

I want to create a timer to update the subtitle screen and check the current time to know what subtitle show on screen. Which is the best to use? NSTimeInterval, NSDate? I think the best is to convert all to times to milliseconds number and compare. But NSTimeInterval works with seconds, not milliseconds. Some clue? Marcos

  • C#/.NET DateTimePicker replacement that "respects" e.g. the CurrentUICulture

    - by S.C. Madsen
    Apparently the DateTimePicker does not "respect" or adhere to the CurrentUICulture of a .NET application, because DateTimePicker is a "Native" Common-control with a .NET wrapper (I think). I have a C#/.NET Winforms application which uses custom-format for the DateTimePickers. Everything seems to be running smoothely except for the "AM/PM" part, which is not shown (I'm guessing this is due to the regional settings of my PC). I have a requirement to display "AM/PM" regardless of the regional settings of the PC running my .NET Winforms application. I would rather not re-implement my own DateTimePicker control, which adheres to the CurrentIUCulture. So does anybody know of a work-around or have a link to DateTimePicker control re-implementation?

  • How do I deep copy a DateTime object?

    - by Billy ONeal
    $date1 = $date2 = new DateTime(); $date2->add(new DateInterval('P3Y')); Now $date1 and $date2 contain the same date -- three years from now. I'd like to create two separate datetimes, one which is parsed from a string and one with three years added to it. Currently I've hacked it up like this: $date2 = new DateTime($date1->format(DateTime::ISO8601)); but that seems like a horrendous hack. Is there a "correct" way to deep copy a DateTime object?

  • Problem with Gallio and TeamCity and the new Visual Studio 2010 release

    - by Bernard Larouche
    I am running TeamCity on a virtual machine. I have installed the new Visual Studio 2010 release yesterday and converted my VS 2008 projects. I also have installed .NET Framework 4 on my virtual machine. Before yesterday all my projects were building succesfully on the CI server but since I installed VS 2010 I get the following error message : error MSB5014: File format version is not recognized. MSBuild can only read solution files between versions 7.0 and 9.0, inclusive. I did change my config on Team City to take into account the new .NET 4 framework : Build Runner : MSBuild Build File Path : CFT.msbuild MSBuild version : Microsoft.NET Framework 4.0 MSBuild ToolsVersion : 4.0 Run Platform : x86 I think it has something to do with the fact that now MSBuild must refer to .NET 4 framwork but it seems that it keeps refering to 2.0.
