  • iPhone dev question: "No provisioned iPhone OS is connected" error, I don't know what else to try fo

    - by dsobol
    Howdy, I am trying to compile and install my first application onto my iPhone after setting up a profile and certificate. At this point I am getting the "No provisioned iPhone OS is connected" error when I Build & Go. I am using iPhone OS 3.1.3, and Xcode 3.2.2 on 10.6.3. • I have verified that my iPhone is connected to my development machine (it is seen on the computer by both iTunes and Xcode Organizer (in Organizer, it has the green dot next to it)). • I have rebooted the iPhone and restarted Xcode multiple times. • I have verified that the Bundle Identifier in my appname.plist is set to com.. (with the appropriate values between the angle brackets). I have looked the error message up on the web, and so far have not found a hint that has gotten me over the hump.... Thanks for any and all assistance! Regards, Steve O'Sullivan

  • Installing a new SQL Server instance fails

    - by Rubio
    I've previously in my setup installed SQL Server Express 2005. Now I've switched to SQL Server Express 2008. I updated the command line parameters to those documented for the latter. If the comp already has SQL Server Express 2008 installed, my installer should create a new instance. The command line parameters are as follows: /ACTION=Install /FEATURES=SQLEngine /QS /INSTANCENAME=ABCD /SECURITYMODE=SQL /SAPWD=CunningPassword The requested instance name does not exist on the target machine. This will end in an error -2068643838. The logs show the following error: "No features were installed during the setup execution. The requested features may already be installed." If I remove the /QS parameter and try to install interactively, I'll get as far as the Feature Selection page. The UI shows three options, Instance Features, Shared Features and Redistributable Features. Whatever I select, clicking Next results in the same error (There are validation errors on this page). Any ideas anyone? Thanks, -- Rubio

  • JSON webservice response compression in IIS 7

    - by denisioru
    Hello! I have trouble with JSON response compression. I look to response headers after uploading website to production server (Windows 2008, IIS 7) and found uncompressed response. Turning on "Enabled static compression" and ""Enable dynamic compression" in IIS control panel does not effect. ASPX pages was responsed gzipped, but webservice response uncompressed. I looked to google, but no answer found about this trouble. Also, I try this http://stackoverflow.com/questions/2405595/json-ihttpmodule-compression way (and adding to web.config this module) - but this source is excellent working at development machine with ASP.NET development server (and have seven times response size reduced) and totally ignored at IIS7. How I can apply gzip compression to json responses from my webservice? Thanks. PS .NET 3.5

  • Change Check Out Folder for checked out files in SourceSafe

    - by Town
    I had to rebuild my machine and went from XP to Windows 7. I've now got a bit of an issue: I had files checked out in SourceSafe previously, which I still have copies of in the local folder on my new install. However, SourceSafe still has them checked out to the old XP folder (c:\documents and settings etc) whereas the files now reside in c:\Users. Pending Checkins in Visual Studio now thinks I have nothing checked out, and SourceSafe declares that the files are checked out to me under the c:\documents and settings\ path. Is there any way to tell SourceSafe to simply "look over there" for the files instead? It seems to work with individually undoing and redoing checkout on the files, but that's a lengthy process and one I'd like to avoid if possible. If I simply checkout the files individually then it lists them as checked out to me twice, one for each of the locations. Any pointers would be very much appreciated!

  • After using modern languages, can C NOT be painful?

    - by Alexandre
    I started my computer engineering course recently and we've been using C for a couple of things. Before starting university, I was doing a lot of web development. I've written a lot of PHP code (yuck!) and for the last year or so Ruby exclusively. aside: I love Ruby, love it! So after a year of heavy Ruby development, is it wrong to think that C should be avoided at all costs unless absolutely necessary? Right now it seems to me I should try to a) get it to run in Ruby b) if it's too slow, try Java c) if it's too slow, use C Is there anyone who jumps straight to C if a VM (Ruby, Java, Python, etc) can be used on the machine and speed is not an issue? In other words, can C NOT be painful?

  • MCM Lab exam this week

    - by Rob Farley
    In two days I’ll’ve finished the MCM Lab exam, 88-971. If you do an internet search for 88-971, it’ll tell you the answer is –883. Obviously. It’ll also give you a link to the actual exam page, which is useful too, once you’ve finished being distracted by the calculator instead of going to the thing you’re actually looking for. (Do people actually search the internet for the results of mathematical questions? Really?) The list of Skills Measured for this exam is quite short, but can essentially be broken down into one word “Anything”. The Preparation Materials section is even better. Classroom Training – none available. Microsoft E-Learning – none available. Microsoft Press Books – none available. Practice Tests – none available. But there are links to Readiness Videos and a page which has no resources listed, but tells you a list of people who have already qualified. Three in Australia who have MCM SQL Server 2008 so far. The list doesn’t include some of the latest batch, such as Jason Strate or Tom LaRock. I’ve used SQL Server for almost 15 years. During that time I’ve been awarded SQL Server MVP seven times, but the MVP award doesn’t actually mean all that much when considering this particular certification. I know lots of MVPs who have tried this particular exam and failed – including Jason and Tom. Right now, I have no idea whether I’ll pass or not. People tell me I’ll pass no problem, but I honestly have no idea. There’s something about that “Anything” aspect that worries me. I keep looking at the list of things in the Readiness Videos, and think to myself “I’m comfortable with Resource Governor (or whatever) – that should be fine.” Except that then I feel like I maybe don’t know all the different things that can go wrong with Resource Governor (or whatever), and I wonder what kind of situations I’ll be faced with. And then I find myself looking through the stuff that’s explained in the videos, and wondering what kinds of things I should know that I don’t, and then I get amazingly bored and frustrated (after all, I tell people that these exams aren’t supposed to be studied for – you’ve been studying for the last 15 years, right?), and I figure “What’s the worst that can happen? A fail?” I’m told that the exam provides a list of scenarios (maybe 14 of them?) and you have 5.5 hours to complete them. When I say “complete”, I mean complete – you don’t get to leave them unfinished, that’ll get you ‘nil points’ for that scenario. Apparently no-one gets to complete all of them. Now, I’m a consultant. I get called on to fix the problems that people have on their SQL boxes. Sometimes this involves fixing corruption. Sometimes it’s figuring out some performance problem. Sometimes it’s as straight forward as getting past a full transaction log; sometimes it’s as tricky as recovering a database that has lost its metadata, without backups. Most situations aren’t a problem, but I also have the confidence of being able to do internet searches to verify my maths (in case I forget it’s –883). In the exam, I’ll have maybe twenty minutes per scenario (but if I need longer, I’ll have to take longer – no point in stopping half way if it takes more than twenty minutes, unless I don’t see an end coming up), so I’ll have time constraints too. And of course, I won’t have any of my usual tools. I can’t take scripts in, I can’t take staff members. Hopefully I can use the coffee machine that will be in the room. I figure it’s going to feel like one of those days when I’ve gone into a client site, and found that the problems are way worse than I expected, and that the site is down, with people standing over me needing me to get things right first time... ...so it should be fine, I’ve done that before. :) If I do fail, it won’t make me any less of a consultant. It won’t make me any less able to help all of my clients (including you if you get in touch – hehe), it’ll just mean that the particular problem might’ve taken me more than the twenty minutes that the exam gave me. @rob_farley PS: Apparently the done thing is to NOT advertise that you’re sitting the exam at a particular time, only that you’re expecting to take it at some point in the future. I think it’s akin to the idea of not telling people you’re pregnant for the first few months – it’s just in case the worst happens. Personally, I’m happy to tell you all that I’m going to take this exam the day after tomorrow (which is the 19th in the US, the 20th here). If I end up failing, you can all commiserate and tell me that I’m not actually as unqualified as I feel.

  • ODBC datasource for DB2 on 64 bit Windows 2008

    - by Rob Vermeulen
    First of all, sorry for this non-programming question. I just finished development of some code that communicates with DB2 and want to test/deploy it on a Windows 2008 machine. I'm a bit concerned about not being able to find a working ODBC datasource (DSN/client) driver for DB2 on Windows 2008 (x64). I have a 32-bit driver for XP but that one (obviously) won't install on 2008-64. The IBM web site comes up with 1844 results when searching for "ODBC Windows 2008", but none of them are relevant. The web site's also a pain to use, btw. While googling around I found some solutions by 3rd party vendors but they all want money :) And the DB2 client and ODBC driver from IBM have always been free-of-charge. Does anyone have a solution?

  • Is it possible to tell IIS 7 to process the request queue in parallel?

    - by Uwe Keim
    Currently we are developing an ASMX, ASP 2.0, IIS 7 web service that does some calculations (and return a dynamically generated document) and will take approx. 60 seconds to run. Since whe have a big machine with multiple cores and lots of RAM, I expected that IIS tries its best to route the requests that arrive in its requests queue to all available threads of the app pool's thread pool. But we experience quiet the opposite: When we issue requests to the ASMX web service URL from multiple different clients, the IIS seems to serially process these requests. I.e. request 1 arrives, is being processed, then request 2 is being processed, then request 3, etc. Question: Is it possible (without changing the C# code of the web service) to configure IIS to process requests in parallel, if enough threads are available? If yes: how should I do it? It no: any workarounds/tips? Thanks Uwe

  • Using Event Driven Programming in games, when is it beneficial?

    - by Arthur Wulf White
    I am learning ActionScript 3 and I see the Event flow adheres to the W3C recommendations. From what I learned events can only be captured by the dispatcher unless, the listener capturing the event is a DisplayObject on stage and a parent of the object firing the event. You can capture the events in the capture(before) or bubbling(after) phase depending on Listner and Event setup you use. Does this system lend itself well for game programming? When is this system useful? Could you give an example of a case where using events is a lot better than going without them? Are they somehow better for performance in games? Please do not mention events you must use to get a game running, like Event.ENTER_FRAME Or events that are required to get input from the user like, KeyboardEvent.KEY_DOWN and MouseEvent.CLICK. I am asking if there is any use in firing events that have nothing to do with user input, frame rendering and the likes(that are necessary). I am referring to cases where objects are communicating. Is this used to avoid storing a collection of objects that are on the stage? Thanks Here is some code I wrote as an example of event behavior in ActionScript 3, enjoy. package regression { import flash.display.Shape; import flash.display.Sprite; import flash.events.Event; import flash.events.EventDispatcher; import flash.events.KeyboardEvent; import flash.events.MouseEvent; import flash.events.EventPhase; /** * ... * @author ... */ public class Check_event_listening_1 extends Sprite { public const EVENT_DANCE : String = "dance"; public const EVENT_PLAY : String = "play"; public const EVENT_YELL : String = "yell"; private var baby : Shape = new Shape(); private var mom : Sprite = new Sprite(); private var stranger : EventDispatcher = new EventDispatcher(); public function Check_event_listening_1() { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { trace("test begun"); addChild(mom); mom.addChild(baby); stage.addEventListener(EVENT_YELL, onEvent); this.addEventListener(EVENT_YELL, onEvent); mom.addEventListener(EVENT_YELL, onEvent); baby.addEventListener(EVENT_YELL, onEvent); stranger.addEventListener(EVENT_YELL, onEvent); trace("\nTest1 - Stranger yells with no bubbling"); stranger.dispatchEvent(new Event(EVENT_YELL, false)); trace("\nTest2 - Stranger yells with bubbling"); stranger.dispatchEvent(new Event(EVENT_YELL, true)); stage.addEventListener(EVENT_PLAY, onEvent); this.addEventListener(EVENT_PLAY, onEvent); mom.addEventListener(EVENT_PLAY, onEvent); baby.addEventListener(EVENT_PLAY, onEvent); stranger.addEventListener(EVENT_PLAY, onEvent); trace("\nTest3 - baby plays with no bubbling"); baby.dispatchEvent(new Event(EVENT_PLAY, false)); trace("\nTest4 - baby plays with bubbling"); baby.dispatchEvent(new Event(EVENT_PLAY, true)); trace("\nTest5 - baby plays with bubbling but is not a child of mom"); mom.removeChild(baby); baby.dispatchEvent(new Event(EVENT_PLAY, true)); mom.addChild(baby); stage.addEventListener(EVENT_DANCE, onEvent, true); this.addEventListener(EVENT_DANCE, onEvent, true); mom.addEventListener(EVENT_DANCE, onEvent, true); baby.addEventListener(EVENT_DANCE, onEvent); trace("\nTest6 - Mom dances without bubbling - everyone is listening during capture phase(not target and bubble phase)"); mom.dispatchEvent(new Event(EVENT_DANCE, false)); trace("\nTest7 - Mom dances with bubbling - everyone is listening during capture phase(not target and bubble phase)"); mom.dispatchEvent(new Event(EVENT_DANCE, true)); } private function onEvent(e : Event):void { trace("Event was captured"); trace("\nTYPE : ", e.type, "\nTARGET : ", objToName(e.target), "\nCURRENT TARGET : ", objToName(e.currentTarget), "\nPHASE : ", phaseToString(e.eventPhase)); } private function phaseToString(phase : int):String { switch(phase) { case EventPhase.AT_TARGET : return "TARGET"; case EventPhase.BUBBLING_PHASE : return "BUBBLING"; case EventPhase.CAPTURING_PHASE : return "CAPTURE"; default: return "UNKNOWN"; } } private function objToName(obj : Object):String { if (obj == stage) return "STAGE"; else if (obj == this) return "MAIN"; else if (obj == mom) return "Mom"; else if (obj == baby) return "Baby"; else if (obj == stranger) return "Stranger"; else return "Unknown" } } } /*result : test begun Test1 - Stranger yells with no bubbling Event was captured TYPE : yell TARGET : Stranger CURRENT TARGET : Stranger PHASE : TARGET Test2 - Stranger yells with bubbling Event was captured TYPE : yell TARGET : Stranger CURRENT TARGET : Stranger PHASE : TARGET Test3 - baby plays with no bubbling Event was captured TYPE : play TARGET : Baby CURRENT TARGET : Baby PHASE : TARGET Test4 - baby plays with bubbling Event was captured TYPE : play TARGET : Baby CURRENT TARGET : Baby PHASE : TARGET Event was captured TYPE : play TARGET : Baby CURRENT TARGET : Mom PHASE : BUBBLING Event was captured TYPE : play TARGET : Baby CURRENT TARGET : MAIN PHASE : BUBBLING Event was captured TYPE : play TARGET : Baby CURRENT TARGET : STAGE PHASE : BUBBLING Test5 - baby plays with bubbling but is not a child of mom Event was captured TYPE : play TARGET : Baby CURRENT TARGET : Baby PHASE : TARGET Test6 - Mom dances without bubbling - everyone is listening during capture phase(not target and bubble phase) Event was captured TYPE : dance TARGET : Mom CURRENT TARGET : STAGE PHASE : CAPTURE Event was captured TYPE : dance TARGET : Mom CURRENT TARGET : MAIN PHASE : CAPTURE Test7 - Mom dances with bubbling - everyone is listening during capture phase(not target and bubble phase) Event was captured TYPE : dance TARGET : Mom CURRENT TARGET : STAGE PHASE : CAPTURE Event was captured TYPE : dance TARGET : Mom CURRENT TARGET : MAIN PHASE : CAPTURE */

  • eclipse xdebug session never completes

    - by Scott
    I am trying to get xdebug working with eclipse (3.5) / php (on xampp windows 7). I have verified xdebug is enabled in php - I have the fancy output and my phpinfo shows all the xdebug stuff. I have remote debug on, and typed in the lan ip address on my eclipse machine. When I tell eclipse to debug, it launches the browser and passes the debug URL parameters. That looks OK. However, in eclipse debug perspective it shows 'launching myproject' 57% 'waiting for xdebug session'. It sits there forever. I have turned off windows firewall on both machines. I tried turning implicit flush on. Any ideas?

    I've got a Django project on my machine and when I try to use South to migrate the data schema, I get several odd errors. Example: $ python manage.py convert_to_south thisLocator /Library/Python/2.6/site-packages/registration/models.py:4: DeprecationWarning: the sha module is deprecated; use the hashlib module instead import sha /Users/cm/code/thisLocator/../thisLocator/batches/models.py:6: DeprecationWarning: the md5 module is deprecated; use hashlib instead import md5 There is no enabled application matching 'thisLocator'. I've followed the South documentation. Settings.py has it in the installed apps, I can run import south from the manage.py shell. Everyone else on my team is calling the app thisLocator. Am I doing something really stupid?

  • WPF 4.0 Font Rendering Issue

    I'm getting a weird rendering issue with WPF 4 applications in the way they render some of the text as it's stretching it and making it very narrow. .net 3.5: .net 4.0: At first I thought it could be a problem with the font, but I'm also seeing the same problem in the Blend 4 beta: I'm running XP SP3, Visual Studio 2010 Professional and everything's as up to date as it can be. I'm not noticing any such problems with Silverlight 4 apps I have built on the same machine... Anyone else seen this or know why it's happening?

  • Trouble with Powershell and running a complex commandline

  • Why does Chrome ignore local jQuery cookies?

    - by Nathan Long
    I am using the jQuery Cookie plugin (download and demo and source code with comments) to set and read a cookie. I'm developing the page on my local machine. The following code will successfully set a cookie in FireFox 3, IE 7, and Safari (PC). But if the browser is Google Chrome AND the page is a local file, it does not work. $.cookie("nameofcookie", cookievalue, {path: "/", expires: 30}); What I know: The plugin's demo works with Chrome. If I put my code on a web server (address starting with http://), it works with Chrome. So the cookie fails only for Google Chrome on local files. Possible causes: Google Chrome doesn't accept cookies from web pages on the hard drive (paths like file:///C:/websites/foo.html) Something in the plugin implentation causes Chrome to reject such cookies Can anyone confirm this and identify the root cause?

  • What is the correct way to import and export out of Excel to SQL Server and back?

    - by Vecdid
    Looking for the correct way and control to import and export of out of Microsoft Excel programmatically. I am willing to get a 3rd party control that supports this functionality, or I can create it myself, but looking to get this prioject done fast. The Datasource will be offline. Although when it is online for the upload/download if there is a control that would merge them, that would work also. But best is to remain offline, don't need the support headache. Security is also an issue. SSIS is not available on the shared database server. The website that hosts the asp.net application is not on the same machine as the sql server. Thank you.

  • How do I check if a swf file loaded correctly since put_Movie always returns S_OK?

    - by Tim
    I am using the latest flash player and have a swf file served locally from my dev machine. In one container test app I am able to play the swf and make calls to it, but in my "Real" application the same code path results in com errors (basically it looks like the swf isn;' loading properly) Additionally this is made more challenging because no matter what nonsense I put in the call to put_Movie() the return is ALWAYS S_OK. This is confusing. How am I supposed to determine if the swf file loaded and is working? As a follow-on, what would cause a swf file (the same one) not to load in a different app? The code paths are the same (from what I can tell). Obviousl something is going on, but I am not sure what. So, I guess 2 questions How to know when swf file doesn't load right Why might it fail in a different container application? I am using ATL in Visual studio 2008, latest flash, MS Vista Thanks

  • My First Weeks at Red Gate

    - by Jess Nickson
    Hi, my name’s Jess and early September 2012 I started working at Red Gate as a Software Engineer down in The Agency (the Publishing team). This was a bit of a shock, as I didn’t think this team would have any developers! I admit, I was a little worried when it was mentioned that my role was going to be different from normal dev. roles within the company. However, as luck would have it, I was placed within a team that was responsible for the development and maintenance of Simple-Talk and SQL Server Central (SSC). I felt rather unprepared for this role. I hadn’t used many of the technologies involved and of those that I had, I hadn’t looked at them for quite a while. I was, nevertheless, quite excited about this turn of events. As I had predicted, the role has been quite challenging so far. I expected that I would struggle to get my head round the large codebase already in place, having never used anything so much as a fraction of the size of this before. However, I was perhaps a bit naive when it came to how quickly things would move. I was required to start learning/remembering a number of different languages and technologies within time frames I would never have tried to set myself previously. Having said that, my first week was pretty easy. It was filled with meetings that were designed to get the new starters up to speed with the different departments, ideals and rules within the company. I also attended some lightning talks being presented by other employees, which were pretty useful. These occur once a fortnight and normally consist of around four speakers. In my spare time, we set up the Simple-Talk codebase on my computer and I started exploring it and worked on my first feature – redirecting requests for URLs that used incorrect casing! It was also during this time that I was given my first introduction to test-driven development (TDD) with Michael via a code kata. Although I had heard of the general ideas behind TDD, I had definitely never tried it before. Indeed, I hadn’t really done any automated testing of code before, either. The session was therefore very useful and gave me insights as to some of the coding practices used in my team. Although I now understand the importance of TDD, it still seems odd in my head and I’ve yet to master how to sensibly step up the functionality of the code a bit at a time. The second week was both easier and more difficult than the first. I was given a new project to work on, meaning I was no longer using the codebase already in place. My job was to take some designs, a WordPress theme, and some initial content and build a page that allowed users of the site to read provided resources and give feedback. This feedback could include their thoughts about the resource, the topics covered and the page design itself. Although it didn’t sound the most challenging of projects when compared to fixing bugs in our current codebase, it nevertheless provided a few sneaky problems that had me stumped. I really enjoyed working on this project as it allowed me to play around with HTML, CSS and JavaScript; all things that I like working with but rarely have a chance to use. I completed the aims for the project on time and was happy with the final outcome – though it still needs a good designer to take a look at it! I am now into my third week at Red Gate and I have temporarily been pulled off the website from week 2. I am again back to figuring out the Simple-Talk codebase. Monday provided me with the chance to learn a bunch of new things: system level testing, Selenium and Python. I was set the challenge of testing a bug fix dealing with the search bars in Simple-Talk. The exercise was pretty fun, although Mike did have to point me in the right direction when I started making the tests a bit too complex. The rest of the week looks set to be focussed on pair programming with Mike as we work together on a new feature. I look forward to the challenges that still face me and hope that I will be able to get up to speed quickly. *fingers crossed*

  • libgdx rotation (animation, arrays) issues and help needed

    - by johnny-b
    well i am a noob at java and libgdx. i got the homing bullet working with the help of someone. now i am smashing my head as to how i can make it rotate so it faces the ball (which is the main character) when it goes around it or when it is coming towards it. the bullet is facing <--- and the code below is what i have done so far. also i used sprites for the bullet and also animation method. Also how do i make it an array/arraylist which is best so i can have multiple bullets at random or placed places. i tried many things nothing workd :( thank you for the help. // below is the bullet or enemy if you want to call it. public class Bullet extends Sprite { public static final float BULLET_HOMING = 6000; public static final float BULLET_SPEED = 300; private Vector2 velocity; private float lifetime; public Bullet(float x, float y) { velocity = new Vector2(0, 0); setPosition(x, y); } public void update(float delta) { float targetX = GameWorld.getBall().getX(); float targetY = GameWorld.getBall().getY(); float dx = targetX - getX(); float dy = targetY - getY(); float distToTarget = (float) Math.sqrt(dx * dx + dy * dy); dx /= distToTarget; dy /= distToTarget; dx *= BULLET_HOMING; dy *= BULLET_HOMING; velocity.x += dx * delta; velocity.y += dy * delta; float vMag = (float) Math.sqrt(velocity.x * velocity.x + velocity.y * velocity.y); velocity.x /= vMag; velocity.y /= vMag; velocity.x *= BULLET_SPEED; velocity.y *= BULLET_SPEED; Vector2 v = velocity.cpy().scl(delta); setPosition(getX() + v.x, getY() + v.y); setOriginCenter(); setRotation(velocity.angle()); lifetime += delta; setRegion(AssetLoader.bulletAnimation.getKeyFrame(lifetime)); } } // this is where i load the images. public class AssetLoader { public static Animation bulletAnimation; public static Sprite bullet1, bullet2; public static void load() { texture = new Texture(Gdx.files.internal("SpriteN1.png")); texture.setFilter(TextureFilter.Nearest, TextureFilter.Nearest); bullet1 = new Sprite(texture, 380, 350, 45, 20); bullet1.flip(false, true); bullet2 = new Sprite(texture, 425, 350, 45, 20); bullet2.flip(false, true); Sprite[] bullets = { bullet1, bullet2 }; bulletAnimation = new Animation(0.06f, aims); bulletAnimation.setPlayMode(Animation.PlayMode.LOOP); } public static void dispose() { // We must dispose of the texture when we are finished. texture.dispose(); } // this is for the rendering of the images etc public class GameRenderer { private Bullet bullet; private Ball ball; public GameRenderer(GameWorld world) { myWorld = world; cam = new OrthographicCamera(); cam.setToOrtho(true, 480, 320); batcher = new SpriteBatch(); // Attach batcher to camera batcher.setProjectionMatrix(cam.combined); shapeRenderer = new ShapeRenderer(); shapeRenderer.setProjectionMatrix(cam.combined); // Call helper methods to initialize instance variables initGameObjects(); initAssets(); } private void initGameObjects() { ball = GameWorld.getBall(); bullet = myWorld.getBullet(); scroller = myWorld.getScroller(); } private void initAssets() { ballAnimation = AssetLoader.ballAnimation; bulletAnimation = AssetLoader.bulletAnimation; } public void render(float runTime) { Gdx.gl.glClearColor(0, 0, 0, 1); Gdx.gl.glClear(GL30.GL_COLOR_BUFFER_BIT); batcher.begin(); // Disable transparency // This is good for performance when drawing images that do not require // transparency. batcher.disableBlending(); // The ball needs transparency, so we enable that again. batcher.enableBlending(); batcher.draw(AssetLoader.ballAnimation.getKeyFrame(runTime), ball.getX(), ball.getY(), ball.getWidth(), ball.getHeight()); batcher.draw(AssetLoader.bulletAnimation.getKeyFrame(runTime), bullet.getX(), bullet.getY()); // End SpriteBatch batcher.end(); } } // this is to load the image etc on the screen i guess public class GameWorld { public static Ball ball; private Bullet bullet; private ScrollHandler scroller; public GameWorld() { ball = new Ball(480, 273, 32, 32); bullet = new Bullet(10, 10); scroller = new ScrollHandler(0); } public void update(float delta) { ball.update(delta); bullet.update(delta); scroller.update(delta); } public static Ball getBall() { return ball; } public ScrollHandler getScroller() { return scroller; } public Bullet getBullet() { return bullet; } } so there is the whole thing. the images are loaded via the AssetLoader then to the GameRenderer and GameWorld via the Bullet class. i am guessing that is how it is. sorry newbie so still learning. thank you in advace for the help or any advice.

  • Unable to send email on production server with ASP.NET MVC

    - by Davide Vosti
    I have a simple ASP.NET MVC application with a contact page. In my development machine (local) I can send successfully emails (I specify host and credentials), but on the production server this doesn't work and I get this error: System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local at System.Net.Mail.SmtpTransport.SendMail... The server is in my LAN (the mail server too). I tried with multiple accounts but I have errors every time. Credentials for the account are provided at runtime with smtp.Credentials = new NetworkCredential("username", "password"); Any idea? Thanks
