  • How to use C# with AIR?

    - by dotnetdev
    I have some basic experience in making Flex sites, but I think I have more use for Flex in making a desktop AIR application. Anyway, I was wondering if it is at least possible to use C# alongside Actionscript/AIR? I can't find any example of this. Also, can I use custom Flash components in a Flex app? I know I can use Javascript components. Thanks

  • Is there a way to identify which web framework is used in a site?

    - by ragu.pattabi
    Whenever I come across a cute website, I am always curious to know which web framework was used by its developers? Being a novice in web development, a look at the page source doesn't give any clue. Any way(s) to get this information? If possible, may be with a bit of Ruby magic, I can figure out things like: which is the most/least used framework for my favorite sites, audio/video heavy sites, etc.

  • Performance of "returning" from a Try block

    - by Mystagogue
    Exception handling on Windows boxes (at least for C++) takes a performance hit if you exit a try block prematurely (such as executing a return statement) the same as if an exception were thrown. But what about C#? Is there a performance hit for returning prematuraly from a try block, whether through a return statement or break statement?

  • Have you ever crashed the compiler?

    - by Motti
    Everyone (at least everyone who uses a compiled language) has faced compilation errors but how many times do you get to actually crash the compiler? I've had my fair share of "internal compiler errors" but most went away just by re-compiling. Do you have a (minimal) piece of code that crashes the compiler?

  • Direct network transfers C#

    - by Wladek
    I was just curious, is it possible to have direct network transfers in c#, without local caching. e.g. I have response stream which represents GoogleDrive file and request stream to upload file to another GoogleDrive account. At that momment I can download file to local pc and next upload it to the google drive. But is it possible to upload it directly from one google drive to another or, at least, start uploading before full download will be completed. Thank

  • OpenGL Video RAM Limits

    - by Tamir
    I have been trying to make a Cross-platform 2D Online Game, and my maps are made of tiles. My tileset, which I render the tiles from, is quite huge. I wanted to know how can I disable hardware rendering, or at least making it more capable. Hence, I wanted to know what are the basic limits of the video ram, as far as I know, Direct3D has a texture size limits (by that I don't mean the power-of-two texture sizes).

  • Is there any reason for an object pool to not be treated as a singleton?

    - by Chris Charabaruk
    I don't necessarily mean implemented using the singleton pattern, but rather, only having and using one instance of a pool. I don't like the idea of having just one pool (or one per pooled type). However, I can't really come up with any concrete situations where there's an advantage to multiple pools for mutable types, at least not any where a single pool can function just as well. What advantages are there to having multiple pools over a singleton pool?

  • Unit Test json output in Zend Framework

    - by lyle
    The Zend Tutorial lists many assertions to check the output generated by a request. http://framework.zend.com/manual/en/zend.test.phpunit.html But they all seem to assume that the output is html. I need to test json output instead. Are there any assertions helpful to check json, or is there at least a generic way to make assertions against the output? Anything that doesn't rely on the request outputting html?

  • How to get ANTLR 3.2 to exit upon first error?

    - by Dan Becker
    In section 10.4, The Definitive ANTLR reference tells you to override mismatch() & recoverFromMismatchedSet() if you want to exit upon the first parsing error. But, at least in ANTLR 3.2, it appears that there is no mismatch() method, and the recoverFromMismatchedSet() documentation says that it is "Not Currently Used". So it appears things have changed since the book was published. What am I supposed to do instead to exit upon the first parsing error in ANTLR 3.2?

  • If tables are so evil, why does joomla use tables for its layout?

    - by DMin
    When you create a template you don't use tables. but when joomla rendereds the page, there are at least 4 places where tables are used to structure the content. Does this tell you something about tables or the fact that the joomla community should invest more time and learn how to code css or just the fact that tables are needed when you don't know what css is going to be throw in later(which probably means they are of some use)?

  • Web-Frameworks for Education Management Systems?

    - by Indebi
    So, I'm working on an idea and I'll go into a brief overview of that but my question is, What are some good web frameworks for this situation? I have some experience in the following languages: C# Python I have considerably more experience in C# than Python, however I am expecting to learn new things. My idea is this, a completely web-based community-oriented Education Management System that focuses on making students and teachers day-to-day lives easier. For students it will provide a centralized place for them to do homework, study for tests, and reinforce concepts learned previously in class. For teachers it will give them a centralized place to handle assignments, attendance, homework, tests, and all other major parts of classroom management. All of that, but in a community-oriented fashion. Everything a teacher does is shared and open to constructive criticism, allowing other teachers to use their assignments/tests and for students or other teachers to comment, rate and criticize their assignments. This encourages an environment of openness that will allow teacher's to focus on teaching and student's to focus on learning. And that community wouldn't be limited to one school or school-district, this system would be completely school-independent. Please note that I have no problem with hearing constructive criticism on this idea, however I would prefer if this post was more focused on my question. I have somewhat explored about the following options: Django ASP.NET Ruby on Rails Silverlight (1) I have Django installed and I played with it for a little bit, I really like how easy setting up databases are and how it handles the database completely for you. I don't really know how to use it very well and I don't quite understand the Model-View-Controller paradigm(?) for it yet but I haven't thought about it much. I also like the fact that it uses Python. (2) I don't really like Visual Studio for developing in ASP.NET, I hate the way the web-designer works and it just feels clunky and old. I like the server-side development part though. I don't like how expensive ASP.NET and overall Visual Studio is, even if I do get it for free for now using DreamSpark (3) I haven't been able to explore much with this, I could not get Rails (or maybe Ruby) properly installed. I first installed it within RadRails and that didn't work so I uninstalled RadRails and then installed the latest version of Ruby off the official Windows Installer and then installed Ruby on Rails through gem and even after all that it still didn't work, so I installed Netbeans and attempted to use it there but it still did not work (4) I like Silverlight in some extents, I've played with this one the most, it's very similar to WPF (which I've used the most) in a lot of ways but I don't like how database connectivity works, at least in comparison to Django. I also dislike how expensive everything with Microsoft is, even if I get it for free for now with DreamSpark. I would like to hear some suggestions from experienced web-developers as to what I should use and why, or at least what some good options are for my scenario Your help would be very appreciated

  • What stereotypes about developers are there?

    - by lkessler
    I was filling out a Delphi Developer Survey and two questions were asking about developer stereotypes: Which stereotype about developers do you think is most true? Which stereotype about developers do you think is least true? That was a hard one for me to answer. I couldn't even think of very many developer stereotypes to choose from. What do you think are the most common ones?

  • Java constructor with large arguments or Java bean getter/setter approach

    - by deelo55
    Hi, I can't decide which approach is better for creating objects with a large number of fields (10+) (all mandatory) the constructor approach of the getter/setter. Constructor at least you enforce that all the fields are set. Java Beans easier to see which variables are being set instead of a huge list. The builder pattern DOES NOT seem suitable here as all the fields are mandatory and the builder requires you put all mandatory parameters in the builder constructor. Thanks, D

  • Android Mapview panning and zooming too slow........

    - by Pratap S
    I've developed a GPS app in which i record the user roots and show it on the map.......but Panning around on the map when reviewing my route is painfully slow, it takes at least 4 or 5 seconds for the map to respond the finger swipes...... I've overridden the onDraw() method and drawing the lines to show the routes......is there any better way to do this so that panning becomes faster as in "MyTracks"........... Thank you all..... Pratap S.

  • What is the difference between Thread.Sleep(timeout) and ManualResetEvent.Wait(timeout)?

    - by Erik Forbes
    Both Thread.Sleep(timeout) and resetEvent.Wait(timeout) cause execution to pause for at least timeout milliseconds, so is there a difference between them? I know that Thread.Sleep causes the thread to give up the remainder of its time slice, thus possibly resulting in a sleep that lasts far longer than asked for. Does the Wait(timeout) method of a ManualResetEvent object have the same problem?

  • jQuery table filter with text, checkboxes, selects

    - by Jeffrey
    Need to filter a table from outside of the table, with a text search, checkboxes, and selects. PicNet Table Filter for jQuery works for both searching and using checkboxes outside of the table... though I can't find any examples of how to get a select box to work. Anyone know? *I might be getting too specific here, but thought I'd at least inquire. I'm also open to possibilities other than PicNet.

  • Google Maps on IPhone won't zoom

    - by Rob Bonner
    Hello, I have an iPhone app that loads the following URL: http://maps.google.com?q=Apple Stores&ll=37.331689,-122.030731&z=3 As expected, the google maps app loads on the phone, but zooms to the entire US. It does not appear to be respecting the z= parameter, or at least, not allowing a zoom level that shows stores in the area.

  • Recommendations for a free GIS library supporting raster images

    - by gspr
    Hi. I'm quite new to the whole field of GIS, and I'm about to make a small program that essentially overlays GPS tracks on a map together with some other annotations. I primarily need to allow scanned (thus raster) maps (although it would be nice to support proper map formats and something like OpenStreetmap in the long run). My first exploratory program uses Qt's graphics view framework and overlays the GPS points by simply projecting them onto the tangent plane to the WGS84 ellipsoid at a calibration point. This gives half-decent accuracy, and actually looks good. But then I started wondering. To get the accuracy I need (i.e. remove the "half" in "half-decent"), I have to correct for the map projection. While the math is not a problem in itself, supporting many map projection feels like needless work. Even though a few projections would probably be enough, I started thinking about just using something like the PROJ.4 library to do my projections. But then, why not take it all the way? Perhaps I might aswell use a full-blown map library such as Mapnik (edit: Quantum GIS also looks very nice), which will probably pay off when I start to want even more fancy annotations or some other symptom of featuritis. So, finally, to the question: What would you do? Would you use a full-blown map library? If so, which one? Again, it's important that it supports using (and zooming in and out with) raster maps and has pretty overlay features. Or would you just keep it simple, and go with Qt's own graphics view framework together with something like PROJ.4 to handle the map projections? I appreciate any feedback! Some technicalities: I'm writing in C++ with a Qt-based GUI, so I'd prefer something that plays relatively nicely with those. Also, the library must be free software (as in FOSS), and at least decently cross-platform (GNU/Linux, Windows and Mac, at least). Edit: OK, it seems I didn't do quite enough research before asking this question. Both Quantum GIS and Mapnik seem very well suited for my purpose. The former especially so since it's based on Qt.

  • Mercurial repo inside a repo

    - by AkiRoss
    Is it possible to create a mercurial repository inside an existing mercurial repository? The idea is to handle subdirectories of a repository as different repositories, how do you do that? I'm not talking about subrepos (at least, if I understood the purpose of subrepos...), but if this is how subrepos do exist for, I got it wrong and I'll try to get it right :) Thanks ~Aki
