  • Getting Reference to Calling Activity from AsyncTask (NOT as an inner class)

    - by stormin986
    Is it at all possible, from within an AsyncTask that is NOT an inner class of the calling Activity class, to get a reference to the instance of Activity that initiated execution of the AsyncTask? I am aware of this thread, however it doesn't exactly address how to reference the calling Activity. Some suggest passing a reference to the Activity as a parameter to the AsyncTask constructor, however, it's reported that doing so will always result in a NullPointerException. So, I'm at a loss. My AsyncTask provides robust functionality, and I don't want to have to duplicate it as an inner class in every Activity that wants to use it. There must be an elegant solution.

  • How to reference filtered ng-repeat items from a controller in AngularJS

    - by ParkerDigital
    I have some JSON data that is rendered out via the ng-repeat directive, and the results are then filtered via some checkboxes/drop-downs, and some custom filter functions in my controller. I now want to add a function to my controller that is triggered by an 'ng-change' on some of the checkboxes, that can reference the current list of items in my 'ng-repeat'. I realise I can reference these values from a custom filter, for example $scope.filterProvider = function(item), but this function is then called for each and every item in the ng-repeat, which isn't what I want - I want the function to just be called each time a checkbox is checked/unchecked, and I need that function to be able to reference the items in my ng-repeat...does that make sense to anyone?! And if so, does anyone know how I can do that? Thanks :-)

  • How to reference other locations in making multi-boot live cd

    - by Nrew
    There is a tool in pen drive linux that allows you to boot directly with multiple iso files. And here is a sample in the menu.lst which allows you to choose which iso file you want to boot. title Fedora 13 find --set-root /Fedora-12-i686-L.iso map /ubuntu-10.04-desktop-i386.iso (0xff) map --hook root (0xff) kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper persistent iso-scan/filename=/ubuntu-10.04-desktop-i386.iso splash initrd /casper/initrd.lz I'm just using it on my 8gb flash drive and the location of the iso file is in the flash drive itself. Is it possible to reference other locations. So that I could boot from it, without limitations. because the flash drive can only contain 8gb of data. Is it possible? Anyone here tried this before?

  • Backup media manager, library or similar reference application

    - by Tarnschaf
    I'm looking for a backup media manager that will keep me up-to-date on where my backups are, how they're stored and what's stored on them. I want it to be able to do and keep track of the following: my used backup media (e.g. DVD1, DVD2) my backed-up assets in high-level (such as "family-photos from 2003", "laptop drivers") details of the assets ("Ninas Birthday 2003") where the backup media is currently stored when the media has been burned (to re-burn in case of media degeneration). It should be possible to navigate back and forth between media and assets. I also thought about marking assets as "deprecated". If all assets on a media are deprecated, the program should tell me so I don't have to keep it any more. Does anyone know of a program with this feature-set? Or will I have to start my own reference in something like Access?

  • Control cell reference increment when dragging a forumula in Libre Office Calc (3.5)

    - by Chuck
    Using Libre Office Calc (3.5) and have a question. When copying a formula that references cells into multiple empty cells the default is to increment each cell reference by one column or row, depending on the direction that the formula is being drug. A formula '= 1 + A1' drug horizontally changes to '= 1 + B1' when pulled one cell to right and '=1 + A2' when pulled one cell down. Is there a way to control increase the increment of the referenced cell? Is is possible to have a formula '= 1 + A1' that effectively changes to '= 1 + A3' when drug down one cell, '= 1 + A5' when drug down two cells, etc? If it matters, I am trying to take a constantly updating master list of data that is organized by dates (Wednesdays and Saturdays) and create separate spread sheets for each day of the week that can be updated by only pulling down the formula into the next cell. My attempts at using the 'lookup' function, 'offset' function, and creating a sort column in Libre Office Calc are thwarted by my inability to figure out how to get around the single step increment when pulling a formula down into the next cell. Thanks

  • How to reference a git repository?

    - by Anonymous
    What should the actual path to a git repository 'file' be? It's common practise when cloning from github to do something like: git clone https://[email protected]/repo.git And I'm used to that. If I init a repo on my local machine using git init, what is the 'git file' for me to reference? I'm trying tot setup Capifony with a Symfony2 project and need to set the repository path. Specifying the folder of the repository isn't working. Is there a .git file for each repository I should be referencing?

  • Lock-Free, Wait-Free and Wait-freedom algorithms for non-blocking multi-thread synchronization.

    - by GJ
    In multi thread programming we can find different terms for data transfer synchronization between two or more threads/tasks. When exactly we can say that some algorithem is: 1)Lock-Free 2)Wait-Free 3)Wait-Freedom I understand what means Lock-free but when we can say that some synchronization algorithm is Wait-Free or Wait-Freedom? I have made some code (ring buffer) for multi-thread synchronization and it use Lock-Free methods but: 1) Algorithm predicts maximum execution time of this routine. 2) Therad which call this routine at beginning set unique reference, what mean that is inside of this routine. 3) Other threads which are calling the same routine check this reference and if is set than count the CPU tick count (measure time) of first involved thread. If that time is to long interrupt the current work of involved thread and overrides him job. 4) Thread which not finished job because was interrupted from task scheduler (is reposed) at the end check the reference if not belongs to him repeat the job again. So this algorithm is not really Lock-free but there is no memory lock in use, and other involved threads can wait (or not) certain time before overide the job of reposed thread. Added RingBuffer.InsertLeft function: function TgjRingBuffer.InsertLeft(const link: pointer): integer; var AtStartReference: cardinal; CPUTimeStamp : int64; CurrentLeft : pointer; CurrentReference: cardinal; NewLeft : PReferencedPtr; Reference : cardinal; label TryAgain; begin Reference := GetThreadId + 1; //Reference.bit0 := 1 with rbRingBuffer^ do begin TryAgain: //Set Left.Reference with respect to all other cores :) CPUTimeStamp := GetCPUTimeStamp + LoopTicks; AtStartReference := Left.Reference OR 1; //Reference.bit0 := 1 repeat CurrentReference := Left.Reference; until (CurrentReference AND 1 = 0)or (GetCPUTimeStamp - CPUTimeStamp > 0); //No threads present in ring buffer or current thread timeout if ((CurrentReference AND 1 <> 0) and (AtStartReference <> CurrentReference)) or not CAS32(CurrentReference, Reference, Left.Reference) then goto TryAgain; //Calculate RingBuffer NewLeft address CurrentLeft := Left.Link; NewLeft := pointer(cardinal(CurrentLeft) - SizeOf(TReferencedPtr)); if cardinal(NewLeft) < cardinal(@Buffer) then NewLeft := EndBuffer; //Calcolate distance result := integer(Right.Link) - Integer(NewLeft); //Check buffer full if result = 0 then //Clear Reference if task still own reference if CAS32(Reference, 0, Left.Reference) then Exit else goto TryAgain; //Set NewLeft.Reference NewLeft^.Reference := Reference; SFence; //Try to set link and try to exchange NewLeft and clear Reference if task own reference if (Reference <> Left.Reference) or not CAS64(NewLeft^.Link, Reference, link, Reference, NewLeft^) or not CAS64(CurrentLeft, Reference, NewLeft, 0, Left) then goto TryAgain; //Calcolate result if result < 0 then result := Length - integer(cardinal(not Result) div SizeOf(TReferencedPtr)) else result := cardinal(result) div SizeOf(TReferencedPtr); end; //with end; { TgjRingBuffer.InsertLeft } RingBuffer unit you can find here: RingBuffer, CAS functions: FockFreePrimitives, and test program: RingBufferFlowTest Thanks in advance, GJ

  • Game Objects Talking To Each Other

    - by PhilCK
    What is a good way of dealing with objects and having them talk to each other? Up until now all my games hobby/student have been small so this problem was generally solved in a rather ugly way, which lead to tight integration and circular dependencies. Which was fine for the size of projects I was doing. However my projects have been getting bigger in size and complexity and now I want to start re-using code, and making my head a simpler place. The main problem I have is generally along the lines of Player needs to know about the Map and so does the Enemy, this has usually descended into setting lots of pointers and having lots of dependencies, and this becomes a mess quickly. I have thought along the lines of a message style system. but I cant really see how this reduces the dependencies, as I would still be sending the pointers everywhere. Thanks. PS: I guess this has been discussed before, but I don't know what its called just the need I have.

  • c# - can you make a "weak" assembly reference to a strong named assembly

    - by Tim
    hi, for various reasons i would rather not use strong named (signed) assemblies in my project. however, one of the projects is referenced by a sharepoint web part which means it must be signed. is it possible to have this assembly signed but when I reference it from other projects, to do so using a non-strong reference. this would give me the advantages of having a non-signed assembly for the rest of my code but still allow it to be loaded by sharepoint Tim

  • Ninject.Web.PageBase still resulting in null reference to injected dependency

    - by Ted
    I have an ASP.NET 3.5 WebForms application using Ninject 2.0. However, attempting to use the Ninject.Web extension to provide injection into System.Web.UI.Page, I'm getting a null reference to my injected dependency even though if I switch to using a service locator to provide the reference (using Ninject), there's no issue. My configuration (dumbed down for simplicity): public partial class Default : PageBase // which is Ninject.Web.PageBase { [Inject] public IClubRepository Repository { get; set; } protected void Page_Load(object sender, EventArgs e) { var something = Repository.GetById(1); // results in null reference exception. } } ... //global.asax.cs public class Global : Ninject.Web.NinjectHttpApplication { /// <summary> /// Creates a Ninject kernel that will be used to inject objects. /// </summary> /// <returns> /// The created kernel. /// </returns> protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(new MyModule()); return kernel; } .. ... public class MyModule : NinjectModule { public override void Load() { Bind<IClubRepository>().To<ClubRepository>(); //... } } Getting the IClubRepository concrete instance via a service locator works fine (uses same "MyModule"). I.e. private readonly IClubRepository _repository = Core.Infrastructure.IoC.TypeResolver.Get<IClubRepository>(); What am I missing? [Update] Finally got back to this, and it works in Classic Pipeline mode, but not Integrated. Is the classic pipeline a requirement? [Update 2] Wiring up my OnePerRequestModule was the problem (which had removed in above example for clarity): protected override IKernel CreateKernel() { var module = new OnePerRequestModule(); module.Init(this); IKernel kernel = new StandardKernel(new MyModule()); return kernel; } ...needs to be: protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(new MyModule()); var module = new OnePerRequestModule(); module.Init(this); return kernel; } Thus explaining why I was getting a null reference exception under integrated pipeline (to a Ninject injected dependency, or just a page load for a page inheriting from Ninject.Web.PageBase - whatever came first).

  • Relative path reference in WebConfig.ConnectionString

    - by Ngu Soon Hui
    Is it possible to specify a relative path reference in connectionstring, attachDbFileName property in a web.config? For example, In my database is located in the App_data folder, I can easily specify the AttachDBFilename as|DataDirectory|\mydb.mdf and the |Datadirectory| will automatically resolve to the correct path. Now, suppose that web.config file is located in A folder, but the database is located in B\App_data folder, where A and B folder is located in the same folder. Is there anyway to use relative path reference to resolve to the correct path?

  • What's the best way to reference a .DLL - as a normal reference or as a web service?

    - by dotnetdev
    Hi, What is the best way to reference an existing .NET dll (Class library)? Is there any benefit to expose web services from the class library and reference these as opposed to referencing the actual .dll (Although one benefit of the web service approach is the granularity and thus surface area exposed is up to you at coding time)? I am thinking with loose coupling in mind, as a criteria. Thanks

  • Javascript reference external script file - security implications

    - by rkrauter
    Hi, If I have a reference to an external third party JavaScript file on my website, what are the security implications? Can the JavaScript file be used to steal cookies? One example of this is the Google Analytics JavaScript reference file. Could the third party technically steal cookies or any other sensitive information from my logged on users (XSS)? The whole cross domain scripting has me confused sometimes. Thanks!

  • Microsoft C++ Language Reference

    - by eSKay
    Whenever any question is asked, and a reference text is needed, I never see MSDN C++ Language Reference being referred. I was browsing through it and I personally feel that it is extremely well written. Is there some specific reason it is not used as often as a standard? Is it because it contains some VC++ specific features?

  • Authoritative Excel range syntax reference

    Sorry if this has been asked before but I can't find it. I am looking for an authoritative description of all valid strings that can be used as a reference, e.g., "A1:C5", "$A:$A", $A2" etc etc. That seems a pretty basic thing yet I've wasted hours trying to locate it. All I can find is a swamp of "helpful" examples but no reference.
