  • Image Size for Animation!

    - by taimur-hamza
    Hi Everybody, I m new to iphone app development and i need some help. I have a list of 30 images that i have to animate and display with 0.1 second interval. I put all the images in an Array using this imageletter.animationImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"1.png"], ...... ,nil] And then animate it using these statements, [imageletter setAnimationDuration:16]; [imageletter startAnimating]; [NSTimer scheduledTimerWithTimeInterval:mytime target:self selector:@selector(StopAfterCertainTime) userInfo:nil repeats:NO]; Now the problem is that the size of each image is 8kb , it runs fine on iphone simulator but crashes on device. When i used 30 other images of 4kb each it runs fine both on simulator and device. Can anybody tell me what is the ideal size for such kind of task. Thanks

  • How can I use a pre-populated core data DB on my device.

    - by KingAndrew
    Hi all, I have developed my app using core data. It works fine in the simulator. When I deploy it to the device the DB is empty. It is 49k where it should be 484k. Basically it is not populated. Since I don't write to the DB when the app is running I need to provide a populated DB to the App. So I copied the populated DB from the simulator to resources and then deploy. Still no luck. the populated DB is in MyApp.app and the AppDelegate is reading from the Documents directory. How do I either get it in the documents directory or get the app delegate to look in the app? Thanks in advance, Andrew

  • How can find out the system default currency symbol on BlackBerry?

    - by ageektrapped
    I have a need to display a currency value in my application. There doesn't seem to be an easy way to do this with the RIM API, so I'm reduced to creating my own solution (a common refrain for BlackBerry development, unfortunately) Currently I'm using the Formatter class, from javax.microedition.locale like so protected String formatResult(double result) { try { Locale l = Locale.getDefaultForSystem(); Formatter formatter = new Formatter(l.toString()); return formatter.formatCurrency(result); } catch (UnsupportedLocaleException e) { return "This fails for the default locale because BlackBerry sucks"; } } I always hit the catch block in the simulator. Since this doesn't work by default on the simulator, I'm hesitant to put it in the application. So I have two questions: Can anyone tell me if the above solution is the way to go? And how to fix it, of course. Is there a way I can retrieve the currency symbol for the current locale programmatically so I can format myself?

  • What is the right way to implement communication between java objects?

    - by imoschak
    I'm working on an academic project which simulates a rather large queuing procedure in java. The core of the simulator rests within one package where there exist 8 classes, each one implementing a single concept. Every class in the project follows SRP. These classes encapsulate the behavior of the simulator and inter-connect every other class in the project. The problem that has arisen is that most of these 8 classes are, as is logical i think, tightly coupled and each one has to have working knowledge of every other class in this package in order to be able to call methods from it when needed. The application needs only one instance of each class so it might be better to create static fields for each class in a new class and use that to make calls -instead of preserving a reference in each class for every other class in the package (which I'm certain that is incorrect)-, but is this considered a correct design solution? or is there a design pattern maybe that better suits my needs?

  • Configuring CESoPSN using Cisco MWR 2941

    - by Rayne
    I'm trying to configure CESoPSN on two Cisco MWR 2941 routers, but the alarm LED lights are always lit. My configuration is modeled after this sample configuration. My setup is as follows: On the Cisco MWRs, E1 0/5 is configured to be CESoPSN, E1 0/9 is configured to be CESoPSN (CAS mode), and E1 0/7 is configured to be SAToP. The two MWRs are connected to each other via the GigabitEthernet port 0/2. The GigE ports are configured as a vlan because the ports are L2 ports and cannot be assigned an IP address directly. The two Cisco MWRs are connected to a traffic simulator, i.e. the traffic simulator will play out E1 traffic to MWR 1 and record the output traffic from MWR 2. On my traffic simulator, when it's connected to the E1 ports 0/5 and 0/9 (both CESoPSN configurations), the "Remote" alarm is on. However, when connected to the E1 ports 0/7 (SAToP configuration), no alarms were on. The GigE connection seems to be working fine (both LED lights on the 2 ports are green). The SAToP configuration seems to be fine too (Left LED is green, right LED is off on both E1 0/7 ports). However, both CESoPSN configurations seem to be not working (Left LED is green, right LED is yellow on both E1 0/5 and 0/9 ports). I don't know if there's anything wrong with my configuration for the CESoPSN, as I'm very new to this. The relevant portions of the configuration are as follows: MWR 1: controller E1 0/5 clock source internal cem-group 5 timeslots 1-31 description E1 CESoPSN example ! controller E1 0/7 clock source internal cem-group 7 unframed description E1 SATOP example ! controller E1 0/9 mode cas clock source internal cem-group 9 timeslots 1-24 description E1 CESoPSN CAS example ! interface Loopback0 ip address 30.30.30.1 255.255.255.255 ! interface GigabitEthernet0/2 switchport access vlan 100 mpls ip ! interface CEM0/5 no ip address cem 5 xconnect 30.30.30.2 305 encapsulation mpls ! ! interface CEM0/7 no ip address cem 7 xconnect 30.30.30.2 307 encapsulation mpls ! ! interface CEM0/9 no ip address cem 9 signaling inband-cas xconnect 30.30.30.2 309 encapsulation mpls ! ! interface Vlan100 ip address 50.50.50.1 255.255.255.0 no ptp enable mpls ip ! no ip classless ip forward-protocol nd ip route 30.30.30.2 255.255.255.255 50.50.50.2 !

  • Dealing with state problems in functional programming

    - by Andrew Martin
    I've learned how to program primarily from an OOP standpoint (like most of us, I'm sure), but I've spent a lot of time trying to learn how to solve problems the functional way. I have a good grasp on how to solve calculational problems with FP, but when it comes to more complicated problems I always find myself reverting to needing mutable objects. For example, if I'm writing a particle simulator, I will want particle "objects" with a mutable position to update. How are inherently "stateful" problems typically solved using functional programming techniques?

  • Implementing traffic conditions in TORCS

    - by user1837811
    I am working on a project about "Effects of Traffic conditions and Track Complexity on Car Driving Behavior". Is it possible to implement traffic in TORCS, or should I use another car simulator? By the word "traffic" I mean there are cars running on both tracks in both directions and I can detect the distances, direction and speed of these cars. Depending on this information I can decide whether I should slow down, speed up and calculate the correct timing to overtake.

  • Getting Started with ADF Mobile Sample Apps

    - by Denis T
    Getting Started with ADF Mobile Sample Apps   Installation Steps Install JDeveloper 11.1.2.3.0 from Oracle Technology Network After installing JDeveloper, go to Help menu and select "Check For Updates" and find the ADF Mobile extension and install this. It will require you restart JDeveloper For iOS development, be on a Mac and have Xcode installed. (Currently only Xcode 4.4 is officially supported. Xcode 4.5 support is coming soon) For Android development, have the Android SDK installed. In the JDeveloper Tools menu, select "Preferences". In the Preferences dialog, select ADF Mobile. You can expand it to select configure your Platform preferences for things like the location of Xcode and the Android SDK. In your /jdeveloper/jdev/extensions/oracle.adf.mobile/Samples folder you will find a PublicSamples.zip. Unzip this into the Samples folder so you have all the projects ready to go. Open each of the sample application's .JWS file to open the corresponding workspace. Then from the "Application" menu, select "Deploy" and then select the deployment profile for the platform you wish to deploy to. Try deploying to the simulator/emulator on each platform first because it won't require signing. Note: If you wish to deploy to the Android emulator, it must be running before you start the deployment.   Sample Application Details   Recommended Order of Use Application Name Description 1 HelloWorld The "hello world" application for ADF Mobile, which demonstrates the basic structure of the framework. This basic application has a single application feature that is implemented with a local HTML file. Use this application to ascertain that the development environment is set up correctly to compile and deploy an application. See also Section 4.2.2, "What Happens When You Create an ADF Mobile Application." 2 CompGallery This application is meant to be a runtime application and not necessarily to review the code, though that is available. It serves as an introduction to the ADF Mobile AMX UI components by demonstrating all of these components. Using this application, you can change the attributes of these components at runtime and see the effects of those changes in real time without recompiling and redeploying the application after each change. See generally Chapter 8, "Creating ADF Mobile AMX User Interface." 3 LayoutDemo This application demonstrates the user interface layout and shows how to create the various list and button styles that are commonly used in mobile applications. It also demonstrates how to create the action sheet style of a popup component and how to use various chart and gauge components. See Section 8.3, "Creating and Using UI Components" and Section 8.5, "Providing Data Visualization." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 4 JavaDemo This application demonstrates how to bind the user interface to Java beans. It also demonstrates how to invoke EL bindings from the Java layer using the supplied utility classes. See also Section 8.10, "Using Event Listeners" and Section 9.2, "Understanding EL Support." 5 Navigation This application demonstrates the various navigation techniques in ADF Mobile, including bounded task flows and routers. It also demonstrates the various page transitions. See also Section 7.2, "Creating Task Flows." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 6 LifecycleEvents This application implements lifecycle event handlers on the ADF Mobile application itself and its embedded application features. This application shows you where to insert code to enable the applications to perform their own logic at certain points in the lifecycle. See also Section 5.6, "About Lifecycle Event Listeners." Note: iOS, the LifecycleEvents sample application logs data to the Console application, located at Applications-Utilities-Console application. 7 DeviceDemo This application shows you how to use the DeviceFeatures data control to expose such device features as geolocation, e-mail, SMS, and contacts, as well as how to query the device for its properties. See also Section 9.5, "Using the DeviceFeatures Data Control." Note: You must also run this application on an actual device because SMS and some of the device properties do not function on an iOS simulator or Android emulator. 8 GestureDemo This application demonstrates how gestures can be implemented and used in ADF Mobile applications. See also Section 8.4, "Enabling Gestures." 9 StockTracker This application demonstrates how data change events use Java to enable data changes to be reflected in the user interface. It also has a variety of layout use cases, gestures and basic mobile patterns. See also Section 9.7, "Data Change Events."

  • Adding program booting options to the OS

    - by user113948
    I am building a flight simulator box, off of Ubuntu 12.10, but I am trying to make the OS essentially invisible, I just want the machine to boot into the Flight Sim, which, that part isn't really that difficult, just a matter of adding a startup item, but I would like to make it a bit more seemless, and in-addtion to that, I would like maybe a 3-5 second countdown where you could opt-out of the flight sim from starting, if you need to troubleshoot the OS, or the flight sim itself, and I have no idea how that would be accomplished

  • How can I disable the CTRL-ALT-DEL key combination completely on XP/Vista/7?

    - by Travesty3
    I have been googling extensively to figure this out, and nobody seems to be able to give a direct answer. Let me start by saying that I'm NOT talking about requiring CTRL-ALT-DEL to enter logon information. I'm working on a golf simulator program which is used at golf centers. I need the ability to completely disable the CTRL-ALT-DEL key sequence so that the golf center customers can't get out of the program and access the computer at all. I realize there are other key combinations that need to be handled as well, we already have this entire feature working in XP, but we're going to be switching to Windows 7 soon, and CTRL-ALT-DEL is the only one that doesn't seem to work in Win7. I'd really like an all-around solution if at all possible. This same program may also be installed on a client's personal computer for an in-home golf simulator, but the computers that really need this feature (golf center computers) are provided to the golf center by us, so would the best option be to write a new shell? I don't know anything about that at all, other than others that suggest writing a new shell for kiosk mode. I'd really like a simpler option, like modifying the registry in some way. I have heard that you can remove some buttons from the menu screen that pops up, but unless I can remove pretty much all of them (including the shutdown/restart button in the bottom-right corner), this won't be enough of a solution for me. Thanks for taking the time to read this and thanks again for any help you could provide! -Travis

  • Xcode warning: application executable contains unsupported architecture(s):arm, arm (-19031)

    - by rmvz3
    Hi all. I've been receiving this warning since I loaded my project in last Xcode 4 preview. There was no warning before that but now I can't get rid of it even in Xcode 3.2. I've been googling but nobody seems to have the same error. My project and target settings are correct (IMHO): Architectures: Standard (armv6 armv7), Base SDK: Latest iOS (currently set to iOS 4.2), Build Active Architecture Only: FALSE, Valid Architectures: armv6 armv7. I compared every project setting with other projects and and found no differences. I even have recreated the project starting from scratch and copying classes, resources and frameworks with the same result. I must say that the warning is not shown when I set Debug configuration. I hope someone can help me because I don't know what to do. Thanks in advice.

  • Fastest way to write large STL vector to file using STL

    - by ljubak
    I have a large vector (10^9 elements) of chars, and I was wondering what is the fastest way to write such vector to a file. So far I've been using next code: vector<char> vs; // ... Fill vector with data ofstream outfile("nanocube.txt", ios::out | ios::binary); ostream_iterator<char> oi(outfile, '\0'); copy(vs.begin(), vs.end(), oi); For this code it takes approximately two minutes to write all data to file. The actual question is: "Can I make it faster using STL and how"?

  • jQTouch with PhoneGap on webOS

    - by Steve Nay
    I'm writing an application in PhoneGap that I want to run on iOS, Android, and webOS. jQTouch plays nice with everything on iOS and Android, but not webOS. Since the webOS Mojo framework is based on Prototype (which uses the $ variable), it's necessary to use jQuery in noConflict mode. I can handle that much. However, the problem is that I also want to use the jQTouch plugin. The jqtouch.js file uses $ throughout, causing JavaScript errors when that file is loaded. Is there a way to run the jQTouch plugin (or any plugin for that matter) in my PhoneGap application without interfering with Prototype?

  • Load binary file using fstream

    - by Kirill V. Lyadvinsky
    I'm trying to load binary file using fstream in the following way: #include <iostream #include <fstream #include <iterator #include <vector using namespace std; int main() { basic_fstream<uint32_t file( "somefile.dat", ios::in|ios::binary ); vector<uint32_t buffer; buffer.assign( istream_iterator<uint32_t, uint32_t( file ), istream_iterator<uint32_t, uint32_t() ); cout << buffer.size() << endl; return 0; } But it doesn't work. In Ubuntu it crashed with std::bad_cast exception. In MSVC++ 2008 it just prints 0. I know that I could use file.read to load file, but I want to use iterator and operator>> to load parts of the file. Is that possible? Why the code above doesn't work?

  • dynamic array pointer to binary file

    - by Yijinsei
    Hi guys, Know this might be rather basic, but I been trying to figure out how to one after create a dynamic array such as double* data = new double[size]; be used as a source of data to be kept in to a binary file such as ofstream fs("data.bin",ios:binary"); fs.write(reinterpret_cast<const char *> (data),size*sizeof(double)); When I finish writing, I attempt to read the file through double* data = new double[size]; ifstream fs("data.bin",ios:binary"); fs.read(reinterpret_cast<char*> (data),size*sizeof(double)); However I seem to encounter a run time error when reading the data. Do you guys have any advice how i should attempt to write a dynamic array using pointers passed from other methods to be stored in binary files?

  • iOS6 MKMapView using a ton of memory, to the point of crashing the app, anyone else notice this?

    - by Jeremy Fox
    Has anyone else, who's using maps in their iOS 6 apps, noticing extremely high memory use to the point of receiving memory warnings over and over to the point of crashing the app? I've ran the app through instruments and I'm not seeing any leaks and until the map view is created the app consistently runs at around ~3mb Live Bytes. Once the map is created and the tiles are downloaded the Live Bytes jumps up to ~13mb Live Bytes. Then as I move the map around and zoom in and out the Live Bytes continuos to climb until the app crashes at around ~40mb Live Bytes. This is on an iPhone 4 by the way. On an iPod touch it crashes even earlier. I am reusing annotation views properly and nothing is leaking. Is anyone else seeing this same high memory usage with the new iOS 6 maps? Also, does anyone have a solution?
