• Reducing moire when downsampling halftone comic images.

  - by drawnonward

  How can I reduce moire effects when downsampling halftone comic book images during live zoom on an iPhone or iPad? I am writing a comic book viewer. It would be nice to provide higher resolution images and allow the user to zoom in while reading the comic book. However, my client is averse to moire effects and will not allow this feature if there are noticeable moire artifacts while zooming, which of course there are. Modifying the images to be less susceptible to moire would only work if the modifications were not perceptible. Blur was specifically prohibited, as is anything that removes the beloved halftone dots. The images are black and white halftone and line art. The originals are 600 dpi but what we ship with the application will be half that at best, so probably 2500 pixels or less tall. So what are my options? If I write a custom downsampling algorithm would it be fast enough for real time on these devices? Are there other tricks I can do? Would it work to just avoid the size ratios that have the most visual moire effects? As you zoom in an out, there are definitely peaks where the moire effects are worst. Is there a way to calculate what those points are and just zoom to a nearby scale that is not as bad? Any suggestions are welcome. I have very little experience with image and signal processing, but am enjoying the opportunity to learn. I know nothing of wavelets and acutance and other jargon, so please be verbose.

• A moral dilemma - What job to go for?

  - by StefanE

  Here is the story: I have accepted an offer from a gaming company to work as an senior test engineer / developer. I have not yet received an signed copy of the contract. I will get a bit less salary then I asked for and it is as well less than I have today. The company have booked flight tickets for my move over there. Now comes the problem. I did an telephone interview with a company last week and they have asked me for an in person interview and are willing to pay for flights for the meeting. This company is my first choice(and have been for a few years) and would also benefit my career and I believe I will enjoy working there more. What should I do here.. I do feel uncomfortable giving a last minute rejection when I have over the phone accepted the offer, but on the other hand they have yet produced a signed contract and as well paying me a bit less than I think I'm worth. The business is small in many ways and I don't want to end up with a bad reputation. Would be great to hear your opinions!

• Is MVVM killing silverlight development?

  - by DeanMc

  This is a question I have had rattling around in my head for some time. I had a chat with a guy the other night who told me he would not be using the navigational framework because he could not figure out how it works with MVVM. As much as I tried to explain that patterns should be taken with a pinch of salt he would not listen. My point is this, patterns are great when they solve some problem. Sometimes only part of the pattern solves a particular problem while the other parts of it cause different problems. The goal of any developer is to build a solid application using a combination of patterns know how and foresight. I feel MVVM is becoming the one pattern to rule them all. As it is not directly supported by .Net some fancy business is needed to make it work. I feel that people are missing the point of the pattern, which is loosely coupled, testable code and instead jumping through hoops and missing out on great experiences trying to follow MVVM to the letter. MVVM is great but I wish it came with a warning or disclaimer for newbies as my fear is people will shy away from silverlight development for fear of being smacked with the mvvm stick. EDIT: Can I just add as an edit, I use and agree with MVVM as a pattern I know when it is and isn't feasible in my projects. My issue is with the encompassing nature it is taking, as if it HAS to be used as part of development. It is being used as an integral feature and not a pattern, which it is.

• Trying to write up a C daemon, but don't know enough C to continue

  - by JamesM-SiteGen

  Okay, so I want this daemon to run in the background with little to no interaction. I plan to have it work with Apache, lighttpd, etc to send the session & request information to allow C to generate a website from an object DB, saving will have to be an option so, you can start the daemon with an existing DB but will not save to it unless you login to the admin area and enable, and restart the daemon. Summary of the daemon: Load a database from file. Have a function to restart the daemon. Allow Apache, lighttpd, etc to get necessary data about the request and session. A varible to allow the database to be saved to the file, otherwise it will only be stored in ram. If it is set to save back to the file, then only have neccessary data in ram. Use sql-light for the database file. Build a webpage from some template files. $(myVar) for getting variables. Get templates from a directory. ./templates/01-test/{index.html,template.css,template.js} Live version of the code and more information: http://typewith.me/YbGB1h1g1p Also I am working on a website CMS in php, but I am tring to switch to C as it is faster than php. ( php is quite fast, but the fact that making a few mySQL requests for every webpage is quite unefficent and I'm sure that it can be far better, so an object that we can recall data from in C would have to be faster ) P.S I am using Arch-Linux not MS-Windows, with the package group base-devel for the common developer tools such as make and makepgk. Edit: Oupps, forgot the question ;) Okay, so the question is, how can I turn this basic C daemon into a base to what I am attempting to do here?

• How to get Facebook Login Button To Display "Logout"

  - by Will Merydith

  I apologize ahead of time if this is clearly documented somewhere on the FB developer site - but I can't find it (so please link me if appropriate). I've implemented the FB login button on a website using GAE + Python. Here is the HTML: <fb:login-button></fb:login-button> <div id="fb-root"></div> <script src="http://connect.facebook.net/en_US/all.js"></script> <script> FB.init({appId: 'ad16a806fc10bef5d30881322e73be68', status: true, cookie: true, xfbml: true}); FB.Event.subscribe('auth.sessionChange', function(response) { if (response.session) { // A user has logged in, and a new cookie has been saved } else { // The user has logged out, and the cookie has been cleared } }); </script> Currently the behavior is - if I click on the "login" button, I am asked to allow the application access to FB. Which I then choose, "OK". But then the login button is still showing "login" and not "logout". How do I implement that? On the server or client side?

• My cocoa app won't capture key events

  - by Oscar

  Hi, i usually develop for iPhone. But now trying to make a pong game in Cocoa desktop application. Working out pretty well, but i can't find a way to capture key events. Here's my code: #import "PongAppDelegate.h" #define GameStateRunning 1 #define GameStatePause 2 #define BallSpeedX 10 #define BallSpeedY 15 @implementation PongAppDelegate @synthesize window, leftPaddle, rightPaddle, ball; - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { gameState = GameStateRunning; ballVelocity = CGPointMake(BallSpeedX, BallSpeedY); [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(gameLoop) userInfo:nil repeats:YES]; } - (void)gameLoop { if(gameState == GameStateRunning) { [ball setFrameOrigin:CGPointMake(ball.frame.origin.x + ballVelocity.x, ball.frame.origin.y + ballVelocity.y)]; if(ball.frame.origin.x + 15 > window.frame.size.width || ball.frame.origin.x < 0) { ballVelocity.x =- ballVelocity.x; } if(ball.frame.origin.y + 35 > window.frame.size.height || ball.frame.origin.y < 0) { ballVelocity.y =- ballVelocity.y; } } } - (void)keyDown:(NSEvent *)theEvent { NSLog(@"habba"); // Arrow keys are associated with the numeric keypad if ([theEvent modifierFlags] & NSNumericPadKeyMask) { [window interpretKeyEvents:[NSArray arrayWithObject:theEvent]]; } else { [window keyDown:theEvent]; } } - (void)dealloc { [ball release]; [rightPaddle release]; [leftPaddle release]; [super dealloc]; } @end

• Collision detections and how efficient they are

  - by Shadow

  How exactly do you implement collision detection? What are the costs involved? Do different platforms(c/c++, java, cocoa/iphone, flash, directX) have different optimizations for calculating collisions. And lastly are there libraries available to do this for me, or some that I can just interpret for my platform of choice? As I understand it you would need to loop through the collision map and find the area in question and then compair the input thing(e.g. a sprite) to the type of pixel that is in the questioned area. I understand the very basic idea, but I don't understand the underlying implementation or even a higher level one for that matter. It would seem that this type of detection, or any for that matter, is very costly. Tile map? Bit array? How are these created from an image(I would guess looping and doing stuff)? The reason I ask this question is to get a better understanding of the efficiency behind the scenes and to understand exactly what is going on. Links, references, or examples would be very helpful. I know this question is a bit longwinded so any help or references would be very welcome. Thanks SO!

• Replace .sln with MSBuild and wrap contained projects into targets

  - by Filburt

  I'd like to create a MSBuild project that reflects the project dependencies in a solution and wraps the VS projects inside reusable targets. The problem I like solve doing this is to svn-export, build and deploy a specific assembly (and its dependencies) in an BizTalk application. My question is: How can I make the targets for svn-exporting, building and deploying reusable and also reuse the wrapped projects when they are built for different dependencies? I know it would be simpler to just build the solution and deploy only the assemblies needed but I'd like to reuse the targets as much as possible. The parts The project I like to deploy <Project DefaultTargets="Deploy" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <ExportRoot Condition="'$(Export)'==''">Export</ExportRoot> </PropertyGroup> <Target Name="Clean_Export"> <RemoveDir Directories="$(ExportRoot)\My.Project.Dir" /> </Target> <Target Name="Export_MyProject"> <Exec Command="svn export svn://xxx/trunk/Biztalk2009/MyProject.btproj --force" WorkingDirectory="$(ExportRoot)" /> </Target> <Target Name="Build_MyProject" DependsOnTargets="Export_MyProject"> <MSBuild Projects="$(ExportRoot)\My.Project.Dir\MyProject.btproj" Targets="Build" Properties="Configuration=Release"></MSBuild> </Target> <Target Name="Deploy_MyProject" DependsOnTargets="Build_MyProject"> <Exec Command="BTSTask AddResource -ApplicationName:CORE -Source:MyProject.dll" /> </Target> </Project> The projects it depends upon look almost exactly like this (other .btproj and .csproj).

• How to debug PHP?

  - by NutMotion

  Anyone's been trying himself at object oriented programming ? Most probably every developer I guess:D I for one have never studied OO design patterns thoroughly, and trying to put it all together now does prove at times thrilling, and many times frustrating also. Even more so when trying to do it in : PHP! All-in-all, my boss asked me to add some Database persistence functions to her server, but most of all, she asked me to translate her already working procedural code into a working Object Oriented code. Here I am, still standing on my PHP OO project. I'm (already) fed up with this "file logging only" PHP capability. I believe there must be some (free or not too much expansive) PHP debugging utility ? I've heard about Zend Studio and PHPEd so far, which didn't quite do the trick for whatever reasons. WIRCW("Which I don't Remember Correctly Why" lol) What say yé? on debugging PHP ? Is there a tool that provides a good debug mode? what's more, don't forget I'm not speaking about the classical web Request/response model. Talking about a debugging facility which can enable you to trigger a web service (aka client request) and go into debug mode on the SOAP web service side. Thks for any input.

• Why are my Flex resource bundles not being loaded?

  - by Chris R

  I have an Actionscript module in the flex source folder filterModules, which is one of two additional source folders in my project (the main source folder is reports, but I'm not dealing with anything in there right now). Here's the MXML content that references the resources. ... This array is assigned to the dataProvider field of a ComboBox. It's not bound using the bindings, presumably for reasons that made sense to the original developer, and it'd be nontrivial to change the class to make that happen. I additionally have a resource property file in a folder resources/en_US and I have the source folder resources/{locale} in the project source settings. My additional compiler options are -locale en_US. The resource property file is resources/en_US/labels.properties (All paths are relative to the flash builder project root) and contains (amongst other things) these keys: metric.q3 = Overall Satisfaction metric.q5 = Personnel metric.q9a = Issue Resolution metric.q42 = Visit Duration Sat metric.q34 = Visit Duration I have written some FlexUnit tests that run in my local Flash Player that exercise these resources -- they check that every label is represented in the metrics array, for example, so I know that the resource file is loaded when run locally. However, when I copy the module .swf file over to my server, the combo box to which the array is assigned is empty. I copy the .swf like so, if it matters: rsync -rlDv --inplace -T /tmp ~/projects/flex_reports/bin-debug/rankingFilter.swf HOSTNAME:WEBROOT/flashPath/ Why is this? I am not able to debug the remote module because our surrounding site sets up a lot of context and makes some database calls to determine which module to load. I'm hoping to get some pointers on why resource bundles might not show up. I'd understand it if the array was present with wrong labels, but the array is instead completely empty, which is pretty odd.

• C# app running as either Windows Form or as Console Application

  - by Aeolien

  I am looking to have one of my Windows Forms applications be run programmatically—from the command line. In preparation, I have separated the logic in its own class from the Form. Now I am stuck trying to get the application to switch back and forth based on the presence of command line arguments. Here is the code for the main class: static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { string[] args = Environment.GetCommandLineArgs(); if (args.Length > 1) // gets passed its path, by default { CommandLineWork(args); return; } Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } private static void CommandLineWork(string[] args) { Console.WriteLine("It works!"); Console.ReadLine(); } where Form1 is my form and the It works! string is just a placeholder for the actual logic. Right now, when running this from within Visual Studio (with command line arguments), the phrase It works! is printed to the Output. However, when running the /bin/Debug/Program.exe file (or /Release for that matter) the application crashes. Am I going about this the right way? Would it make more sense (i.e. take less developer time) to have my logic class be a DLL that gets loaded by two separate applications? Or is there something entirely different that I'm not aware of? Thanks in advance!

• Single Responsibility Principle vs Anemic Domain Model anti-pattern

  - by Niall Connaughton

  I'm in a project that takes the Single Responsibility Principle pretty seriously. We have a lot of small classes and things are quite simple. However, we have an anemic domain model - there is no behaviour in any of our model classes, they are just property bags. This isn't a complaint about our design - it actually seems to work quite well During design reviews, SRP is brought out whenever new behaviour is added to the system, and so new behaviour typically ends up in a new class. This keeps things very easily unit testable, but I am perplexed sometimes because it feels like pulling behaviour out of the place where it's relevant. I'm trying to improve my understanding of how to apply SRP properly. It seems to me that SRP is in opposition to adding business modelling behaviour that shares the same context to one object, because the object inevitably ends up either doing more than one related thing, or doing one thing but knowing multiple business rules that change the shape of its outputs. If that is so, then it feels like the end result is an Anemic Domain Model, which is certainly the case in our project. Yet the Anemic Domain Model is an anti-pattern. Can these two ideas coexist? EDIT: A couple of context related links: SRP - http://www.objectmentor.com/resources/articles/srp.pdf Anemic Domain Model - http://martinfowler.com/bliki/AnemicDomainModel.html I'm not the kind of developer who just likes to find a prophet and follow what they say as gospel. So I don't provide links to these as a way of stating "these are the rules", just as a source of definition of the two concepts.

• Trying to convert existing production database table columns from enum to VARCHAR (Rails)

  - by dchua

  Hi everyone, I have a problem that needs me to convert my existing live production (I've duplicated the schema on my local development box, don't worry :)) table column types from enums to a string. Background: Basically, a previous developer left my codebase in absolute shit, migration versions are extremely out of date, and apparently he never used it after a certain point of time in development and now that I'm tasked with migrating a rails 1.2.6 app to 2.3.5, I can't get the tests to run properly on 2.3.5 because my table columns have ENUM column types and they convert to :string, :limit = 0 on my schema.rb which creates the problem of an invalid default value when doing a rake db:test:prepare, like in the case of: Mysql::Error: Invalid default value for 'own_vehicle': CREATE TABLE `lifestyles` (`id` int(11) DEFAULT NULL auto_increment PRIMARY KEY, `member_id` int(11) DEFAULT 0 NOT NULL, `own_vehicle` varchar(0) DEFAULT 'Y' NOT NULL, `hobbies` text, `sports` text, `AStar_activities` text, `how_know_IRC` varchar(100), `IRC_referral` varchar(200), `IRC_others` varchar(100), `IRC_rdrive` varchar(30)) ENGINE=InnoDB I'm thinking of writing a migration task that looks through all the database tables for columns with enum and replace it with VARCHAR and I'm wondering if this is the right way to approach this problem. I'm also not very sure how to write it such that it would loop through my database tables and replace all ENUM colum_types with a VARCHAR. References [1] https://rails.lighthouseapp.com/projects/8994/tickets/997-dbschemadump-saves-enum-columns-as-varchar0-on-mysql [2] http://dev.rubyonrails.org/ticket/2832

• Practical rules for premature optimization

  - by DougW

  It seems that the phrase "Premature Optimization" is the buzz-word of the day. For some reason, iphone programmers in particular seem to think of avoiding premature optimization as a pro-active goal, rather than the natural result of simply avoiding distraction. The problem is, the term is beginning to be applied more and more to cases that are completely inappropriate. For example, I've seen a growing number of people say not to worry about the complexity of an algorithm, because that's premature optimization (eg http://stackoverflow.com/questions/2190275/help-sorting-an-nsarray-across-two-properties-with-nssortdescriptor/2191720#2191720). Frankly, I think this is just laziness, and appalling to disciplined computer science. But it has occurred to me that maybe considering the complexity and performance of algorithms is going the way of assembly loop unrolling, and other optimization techniques that are now considered unnecessary. What do you think? Are we at the point now where deciding between an O(n^n) and O(n!) complexity algorithm is irrelevant? What about O(n) vs O(n*n)? What do you consider "premature optimization"? What practical rules do you use to consciously or unconsciously avoid it? This is a bit vague, but I'm curious to hear other peoples' opinions on the topic.

• Our GUI Situation

  - by shawn-harrison

  These days, any decent Windows desktop application must perform well and look good under the following conditions: 1) XP and Vista and Windows 7. 2) 32 bit and 64 bit. 3) With and without Themes. 4) With and without Aero. 5) At 96 and 120 and perhaps custom DPIs. 6) One or more monitors (screens). 7) Each OS has it's own preferred Font. Oh My! What is a lowly little Windows desktop application developer to do :(. I'm hoping to get a thread started with suggestions on how to deal with this Gui dilemma. First off, I'm on Delphi 7. a) Does Delphi 2010 bring anything new to the table to help with this situation? b) Should we pick an aftermarket component suite and rely on them to solve all these problems? c) Should we go with an aftermarket skinning engine? d) Perhaps a more html type gui is the way to go. Can we make a relatively complex gui app with html that doesn't require using a browser? (prefer to keep it form based) e) Should we just knuckle down and code through each one of these scenarios and quit bitching about it? f) And finally, how in the world are we supposed to test all these conditions? thanks, shawnH

• How to hold payment in paygate for a while?

  - by Fero

  HI all, I have a query regarding holding the payment in PAYGATE PAYMENT GATEWAY. Here is the problem in brief. I am doing a website where the payment should be made only a certain members buy the product. For Example if there is an iPhone in my site, then that particular phone must be buy by certain quantities which given by admin. It may be done one by one user or a single user can buy all the quantities at a single time. In this case as a developer how can i able to hold the payment which received by user? Because i don't want to receive the payments until the certain quantities bought. Because if certain quantities were not buy i need to refund the money to their account. We don't like to do this process. That's why we are looking for holding the payment. Is it possible or what is the best way to solve this problem? Please let me know what is you professional opinion? thanks in advance... Please let me know what is you professional opinion?

• GL_COLOR_MATERIAL with lighting on Android

  - by kostmo

  It appears that glColorMaterial() is absent from OpenGL ES. According to this post (for iPhone), you may still enable GL_COLOR_MATERIAL in OpenGL ES 1.x, but you're stuck with the default settings of GL_FRONT_AND_BACK and GL_AMBIENT_AND_DIFFUSE that you would otherwise set with glColorMaterial(). I would be OK with this, but the diffuse lighting is not working correctly. I set up my scene and tested it with one light, setting glMaterialfv() for GL_AMBIENT and GL_DIFFUSE once in the initialization. The normals have been set correctly, and lighting works the way it's supposed to. I see the Gourad shading. With GL_LIGHTING disabled, the flat colors I have set with glColor4f() appear on the various objects in the scene. This also functions as expected. However, when glEnable(GL_COLOR_MATERIAL) is called, the flat colors remain. I would expect to see the lighting effects. What might be missing? glColorMaterial() is also mentioned on anddev.org, but I'm not sure if the information there is accurate. I'm testing this on an Android 2.1 handset (Motorola Droid). Edit: It works properly on my 1.6 handset (ADP1).

• Getting auth token for dropbox account from accountmanager in android

  - by user1490880

  I am trying to get auth token for a dropbox account configured in device from account manager. I am using accountManager.getAuthToken(account, "DROPBOX",null,Hello.this, new GetAuthTokenCallback(), null);//account" is dropbox account I am seeing a Allow/Deny page. I click on Allow, but the callback is not getting invoked at all and i dont get the auth token. I got the authtoken for a google account with this(with a different authtokentype). What i am missing. I am not sure about the authTokenType parameter for dropbox. Also are there any other parameter specific for dropbox like the bundle parameter that i am missing. Is this way possible for dropbox? Check below for the function parameters public AccountManagerFuture<Bundle> getAuthToken (Account account, String authTokenType, Bundle options, Activity activity, AccountManagerCallback<Bundle> callback, Handler handler) Link: http://developer.android.com/reference/android/accounts/AccountManager.html UPDATE I assume since we are able to create a dropbox account in android Accounts and Sync(Settings), there must be a dropbox authenticator that has all the functions in AbstractAccountAuthenticator implemented including getAuthToken(). So dropbox should support giving auth token i think. Also dropbox uses oauth1, whereas account manager uses outh 2.0. So is this an issue.Can anyone comment on this?

• How to start AJAX in Zend?

  - by Awan

  I am working on some projects as a developer(PHP,MySQL) in which AJAX and jQuery is already implemented. But now I want to learn implementation of AJAX and jQuery stuff. Can anyone tell me the exact steps with explanation? I have created a project in Zend. There is only one controller(IndexController) and two actions(a and b) in my project now. Now I want to use ajax in my project. But I don't know how to start. I read some tutorial but unable to completely understand. I have index.phtml like this: <a href='index/a'>Load info A</a> <br/> <a href='index/b'>Load info B</a> <br /> <div id=one>load first here<div> <div id=two>load second here</div> Here index is controller in links. a and b are actions. now I have four files like this: a1.phtml I am a1 a2.phtml I am a2 b1.phtml I am b1 b2.phtml I am b2 I think you have got my point. When user clicks first link (Load info A) then a1.phtml should be loaded into div one and a2.phtml should be loaded into div two When user clicks second link (Load info B) then b1.phtml should be loaded into div one and b2.phtml should be loaded into div two And someone tell me the purpose of JSON in this process and how to use this also? Thanks

• Paypal Encrypted Website payments

  - by John Isaacks

  I am trying to integrate a PayPal Website Payments Standard Cart Upload payment type into my shopping cart. I integrated Google Checkout a while back and I did not find it overly confusing as I do paypal. I am getting info on how to encrypt it from here: https://cms.paypal.com/us/cgi-bin/?&cmd=_render-content&content_ID=developer/e_howto_html_encryptedwebpayments#id08A3I0P017Q Paypal says I need to generate a private key and a public certificate using OpenSSL. I went to OpenSSL and downloaded the latest release, which is just a folder containing various files but I see no application I can use, not sure what to do here. Even if I were to get OpenSSL to generate me a private key and public cert, the next step is to download either an MS or Java command line tool to create the encrypted cart ahead of time with the cart-total, tax, etc. which sounds crazy to me, like I am supposed to manually do this prior to every order?? Obviously I do not know the items in the cart the customer is going to buy before hand so I need this to be done on the fly on my website using PHP. But I am completely lost. There has to be a way to setup dynamic secure cart uploads to paypal. Can someone please point me in the right direction?

I am not getting how admob banner is comes in every class in fact i have not declare in Rootviewcontroller class. can any one suggest me how to integrate Admob in cocos2d game, i want Admob banner in particular classes not in every class, I am using latest google admob sdk, my code is below: Thanks in advance ` -(void)AdMob{ NSLog(@"ADMOB"); CGSize winSize = [[CCDirector sharedDirector]winSize]; // Create a view of the standard size at the bottom of the screen. if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){ bannerView_ = [[GADBannerView alloc] initWithFrame:CGRectMake(size.width/2-364, size.height - GAD_SIZE_728x90.height, GAD_SIZE_728x90.width, GAD_SIZE_728x90.height)]; } else { // It's an iPhone bannerView_ = [[GADBannerView alloc] initWithFrame:CGRectMake(size.width/2-160, size.height - GAD_SIZE_320x50.height, GAD_SIZE_320x50.width, GAD_SIZE_320x50.height)]; } if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { bannerView_.adUnitID =@"a15062384653c9e"; } else { bannerView_.adUnitID =@"a15062392a0aa0a"; } bannerView_.rootViewController = self; [[[CCDirector sharedDirector]openGLView]addSubview:bannerView_]; [bannerView_ loadRequest:[GADRequest request]]; GADRequest *request = [[GADRequest alloc] init]; request.testing = [NSArray arrayWithObjects: GAD_SIMULATOR_ID, nil]; // Simulator [bannerView_ loadRequest:request]; } //best practice for removing the barnnerView_ -(void)removeSubviews{ NSArray* subviews = [[CCDirector sharedDirector]openGLView].subviews; for (id SUB in subviews){ [(UIView*)SUB removeFromSuperview]; [SUB release]; } NSLog(@"remove from view"); } //this makes the refreshTimer count -(void)targetMethod:(NSTimer *)theTimer{ //INCREASE OF THE TIMER AND SECONDS elapsedTime++; seconds++; //INCREASE OF THE MINUTOS EACH 60 SECONDS if (seconds>=60) { seconds=0; minutes++; [self removeSubviews]; [self AdMob]; } NSLog(@"TIME: %02d:%02d", minutes, seconds); } `

• GWT Animation final value is not respected

  - by brad

  I have a FlowPanel that I'm trying to animate back and forth like an iphone nav. (See this post for my original question on how to do this) So I have it "working" with the code shown below. I say working in quotes because I'm finding that my final position of my scroller is not precise and always changes when scrolling. The GWT.log always says the actual values I'm looking for, so for instance with the call below to scrollTo, my GWT.log says: ScrollStart: 0 scrollStop: -246 But when I actually analyze the element in fireBug, its css, left position is never exactly -246px. Sometimes it's off by as much as 10px so my panel has just stopped scrolling before being finished. The worst part is that this nav animates back and forth, so subsequent clicks can really throw it off, and I need pixel perfect positioning otherwise the whole things looks off. I don't even know where to start with debugging this other than what I've already done. Any tips are appreciated. Code to call animation scroller = new Scroller(); scroller.scrollTo(-246,400); Animation Code public class Scroller extends Animation { private FlowPanel scroller; private final Element e; public Scroller(){ scroller = new FlowPanel(); e = scroller.getElement(); } public void scrollTo(int position, int milliseconds) { scrollStart = e.getOffsetLeft(); scrollStop = position; GWT.log("ScrollStart: " + scrollStart + " scrollStop: " + scrollStop); run(milliseconds); } @Override protected void onUpdate(double progress) { double position = scrollStart + (progress * (scrollStop - scrollStart)); e.getStyle().setLeft(position, Style.Unit.PX); } }

• Compiling gstreamer plugin in windows

  - by utnapistim

  Hello all, My question: What is the correct way to compile a gstreamer plugin in windows, so that it will be accepted by gstreamer (actually Songbird on top of gstreamer). My setup: I have downloaded the songbird sources following the steps described here and I have a trunk/dependencies/windows-i686-msvc8 directory within my svn sources with all the gstreamer binaries. I have created a gstreamer empty plugin skeleton following the steps detailed in the GStreamer Plugin Writer's Guide, and compiled it against the gstreamer binaries in the Songbird dependencies folder. The compilation was done with VS2010 RC1 (Visual Studio 2008 yelded the same results), using an empty DLL project with the .h and .c files generated using the GStreamer Plugin Writer's Guide. The DLL was lined with libcpmt.lib, libcmt.lib, ws2_32.lib, gobject-2.0.lib, gthread-2.0.lib, gstreamer-0.10-0.lib, glib-2.0.lib, kernel32.lib, nspr4.lib and ignoring all default libraries. I have compiled the files as both .c and .cpp with the same results. Testing: I have installed the Songbird binaries corresponding to the correct svn version, then installed Songbird Developer Tools addon and used it to create an addon for testing my gstreamer plugin. Songbird will not load the pluggin. I have also tried to load it with gst-launch.exe from the trunk/dependencies/windows-i686-msvc8/[...] directory and that generated runtime error R6034: An application has made an attempt to load the C runtime library incorrectly. Most resources I found for this problem recommended restarting or reinstalling windows :(.

• What happened to the .NET version definition with v4.0?

  - by Tom Tresansky

  I'm building a C# class library, and using the beta 2 of Visual Web Developer/Visual C# 2010. I'm trying to save information about what version of .NET the library was built under. In the past, I was able to use this: // What version of .net was it built under? #if NET_1_0 public const string NETFrameworkVersion = ".NET 1.0"; #elif NET_1_1 public const string NETFrameworkVersion = ".NET 1.1"; #elif NET_2_0 public const string NETFrameworkVersion = ".NET 2.0"; #elif NET_3_5 public const string NETFrameworkVersion = ".NET 3.5"; #else public const string NETFrameworkVersion = ".NET version unknown"; #endif So I figured I could just add: #elif NET_4_0 public const string NETFrameworkVersion = ".NET 4.0"; Now, in Project-Properties, my target Framework is ".NET Framework 4". If I check: Assembly.GetExecutingAssembly().ImageRuntimeVersion I can see my runtime version is v4.0.21006 (so I know I have .NET 4.0 installed on my CPU). I naturally expect to see that my NETFrameworkVersion variable holds ".NET 4.0". It does not. It holds ".NET version unknown". So my question is, why is NET_4_0 not defined? Did the naming convention change? Is there some simple other way to determine .NET framework build version in versions 3.5?
