  • jQuery cycle query

    - by Happy
    We have a script used for each .item: $(".item").each(function(){ item_link = "http://..."; block = $('.block', this); $.get(item_link, function(data) { var src = $('img.slide', data).attr('src'); block.html(src); }); }); item_link variable is uniquie for each query. There can be 100 .item or more. The problem is - server has limit on connections at the same time, that why some .item get var src, some not. The best solution is to use just one .get at the same time. I think there should be some counter, if .get is finished - it gives message "I'm finished, you can start" to the next .get and so on. How to do that? Thanks.

  • Declaring two classes that contain instance variables of each others' types.

    - by Benji XVI
    Let’s say you wish to have two classes like so, each declaring an instance variable that is of the other’s class. @interface A : NSObject { B *something; } @end @interface B : NSObject { A *something; } @end It seems to be impossible to declare these classes with these instance variables. In order for A to include an IV of class B, B must already be compiled, and so its @interface must come before A’s. But A’s must be put before B’s for the same reason. Putting the two class declarations in separate files, and #import-ing each other’s .h doesn’t work either, for obvious reasons. So, what is the solution? Or is this either (1) impossible or (2) indicative of a bad design anyway?

  • can I get .class from generic type argument?

    - by Mike S
    I have the following class: public abstract class MyClass<T extends Object> { protected T createNewFromData(Reader reader){ GSON.fromJSON(reader,T.class); // T.class isn't allowed :( } } How do I pass a Class<T instance into there? Is there some wierd and wacky work around? Is there a way to get a Class<T reference other than from a pre-instantiated Object of type T? It won't let me do this either: T t = new T(); Class<T> klass = t.class; ANSWER BELOW Thanks to the accepted answer, here is the solution: Type type = new TypeToken<T>(){}.getType(); return gson.fromJson(reader, type);

  • Is it poor practice to identify objects via an enumeration property, instead of using GetType()?

    - by James
    I have a collection of objects that all implement one (custom) interface: IAuditEvent. Each object can be stored in a database and a unique numeric id is used for each object type. The method that stores the objects loops around a List<IAuditEvent>, so it needs to know the specific type of each object in order to store the correct numeric id. Is it poor practice to have an enumeration property on IAuditEvent so that each object can identify itself with a unique enumeration value? I can see that the simplest solution would be to write a method that translates a Type into an integer, but what if I need an enumeration of audit events for another purpose? Would it still be wrong to have my enumeration property on IAuditEvent?

  • using eclipse to connect to remote machine[linux server] using ssh

    - by lalit
    Hi, I am searching out for solution to use any of the IDE's such as Netbeans/ eclipse to run .jsp and .java files from a remote machine using linux as the OS. The .java and .jsp files are on the server . So, an IDE which would let me access the server and let me update the files directly on the server would be great. I use SSH terminal to connect to the server to update and get files. Now, if there was an easier way to just have an access using IDE to the linux remote machine. that would be great. Please let me know regarding the same. Thank you very much for your time. Regards.

  • How to change the name of an iPhone app?

    - by Robert Gould
    I began an iPhone project the other day with a silly development code name, and now I want to change the name of the project since its nearly finished. But I'm not sure how to do this with XCode, trying the obvious of changing the application's name in the pinfo, causes the signing process to go wrong (I think...) and my app won't launch giving me a Launcher error. I guess I could make a new project and copy paste everything over, but it seems so primitive, that I'm hoping for a more civilized solution. Thanks!

  • Python 2.7 creating a multidimensional list

    - by poop
    I don't know why I am having so much trouble creating a 3 dimensional list. I need the program to create an empty n by n list. So for n = 4: x = [[[],[],[],[]],[[],[],[],[]],[[],[],[],[]],[[],[],[],[]]] I've tried using: y = [n*[n*[]]] y = [[[]]* n for i in range(n)] Which both appear to be creating copies of a reference. I've also tried naieve application of the list builder with little success: y = [[[]* n for i in range(n)]* n for i in range(n)] y = [[[]* n for i in range(1)]* n for i in range(n)] I've also tried building up the array iteratively using loops, with no success. In my rapid flurry of attempts to not post something stupidly easy to SO, I came upon a solution: y = [] for i in range(0,n): y.append([[]*n for i in range(n)]) Is there an easier/ more intuitive way of doing this?

  • how divide herader from binary data

    - by fixo2020
    Hi, I have this code: ofstream dest("test.txt",ios::binary); while (true){ size_t retval = recv (sd, buffer, sizeof(buffer), 0); dest.write(buffer,retval); if(retval <= 0) { delete[] buffer; break;} } Now, the recv() function return 4 bytes each loop right? and buffer contain it, this return all data so, pseudo-header and binary data (image), but I want know how capture only binary data, I know that the end of header are "\n\r" right? but what's are the solution better for make this? I make a function that detect when are "\n\r"? and after how capture binary data? Or, I put all data in memory, and after parse it? but how? I'm desperate :(

  • Optimal strategy to make a C++ hash table, thread safe

    - by Ajeet
    (I am interested in design of implementation NOT a readymade construct that will do it all.) Suppose we have a class HashTable (not hash-map implemented as a tree but hash-table) and say there are eight threads. Suppose read to write ratio is about 100:1 or even better 1000:1. Case A) Only one thread is a writer and others including writer can read from HashTable(they may simply iterate over entire hash table) Case B) All threads are identical and all could read/write. Can someone suggest best strategy to make the class thread safe with following consideration 1. Top priority to least lock contention 2. Second priority to least number of locks My understanding so far is thus : One BIG reader-writer lock(semaphore). Specialize the semaphore so that there could be eight instances writer-resource for case B, where each each writer resource locks one row(or range for that matter). (so i guess 1+8 mutexes) Please let me know if I am thinking on the correct line, and how could we improve on this solution.

  • ActionScript - One Button Limit (Exclusive Touch) For Mobile Devices?

    - by TheDarkIn1978
    two years ago, when i was developing an application for the iPhone, i used the following built-in system method on all of my buttons: [button setExclusiveTouch:YES]; essentially, if you had many buttons on screen, this method insured that the application wouldn't be permitted do crazy things when several button events firing at the same time. problematic: ButtonA and ButtonB are available. each button has a mouse up event which fire a specific reorganization/layout of the UI. if both button's events are fired at the same time, their events will likely conflict, causing a strange new layout, perhaps a runtime error. solution: application buttons cancel any current pending mouse up events when said button enters mouse down. private function mouseDownEventHandler(evt:MouseEvent):void { //if other buttons are currently in a mouse down state ready to fire //a mouse up event, cancel them all here. } of course it's simple to manually handle this if there are only a few buttons on stage, but managing buttons becomes more and more complicated / bug-prone if there are several / many buttons available. is there a convenience method available in AIR specifically for this functionality?

  • Number 0 is not saving to database as a prefix in SQL Server of CHAR data type column

    - by gmhk
    I am trying to insert an value as '019393' into a table with a CHAR(10) column. It is inserting only '19393' into the database I am implementing this feature in a stored procedure, doing some manipulation like incrementing that number by 15 and saving it back with '0' as the prefix I am using SQL Server database Note: I tried CASTING that value as VARCHAR before saving to the database, but even that did not get the solution Code SELECT @fromBSB = fromBSB, @toBSB = toBSB, @type = Type FROM [dbo].[tbl_REF_SpecialBSBRanges] WHERE CAST(@inputFromBSB AS INT) BETWEEN fromBSB AND toBSB SET @RETURNVALUE = @fromBSB IF(@fromBSB = @inputFromBSB) BEGIN PRINT 'Starting Number is Equal'; DELETE FROM tbl_REF_SpecialBSBRanges WHERE Type = @type AND fromBSB = @fromBSB AND toBSB = @toBSB INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@type, CAST('0' + @fromBSB + 1 AS CHAR), @toBSB) INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@inputBSBName, @inputFromBSB, @inputToBSB) END

  • C++ methods which take templated classes as argument.

    - by Nils
    I have a templated class Vector<class T, int N> Where T is the type of the components (double for example) and n the number of components (so N=3 for a 3D vector) Now I want to write a method like double findStepsize(Vector<double,2> v) {..} I want to do this also for three and higher dimensional vectors. Of course I could just introduce further methods for higher dimensions, but the methods would have a lot of redundant code, so I want a more generic solution. Is there a way to create a method which takes a templated class without further specializing it (in this case without specifying T or N)? Like double findStepsize(Vector<T,N> v) ?

  • Insert a row and avoiding race condition (PHP/MySQL)

    - by justkevin
    I'm working on a multiplayer game which has a lobby-like area where players select "sectors" to enter. The lobby gateway is powered by PHP, while actual gameplay is handled by one or more Java servers. The datastore is MySQL. The happy path: A player chooses a sector and tells the lobby he'd like to enter. The lobby checks whether this is okay, including checking whether there are too many players in the sector (compares the entry count in sector assignments for that sector against the sector's max_players value). The player is added to the sector_assignments table pairing him with the sector. The player client receives a passkey that will let him connect to the appropriate game server. The race condition: If two players request access to the same sector at close to same time, I can envision a case where they are both added because there was one space free when their check was started and max players gets exceeded. Is the best solution LOCK TABLE on sector_assignments? Is there another option?

  • Picking photo from Photochooser or holding hardware back button cause active timers ring

    - by Nznoonee
    This is very strange problem, and all the people I had asked to confirm it said that it takes place. I have a Threading.Timer instance which fires every 15 minutes. And if I call the PhotoChooser view and then select a photo from it, when going back to the calling page my application calls that timer's callback! I tried different timers either it be Timer from Threading namespace or Dispatcher timer. The same happens when being in my app I hold the back button of my device and then choose the app from the list. My application is as plain as it can be - the timer with a callback and method calling PhotoChooser. Could anyone help with solution or workaround please?

  • What to do if 2 (or more) relationship tables would have the same name?

    - by primehunter326
    So I know the convention for naming M-M relationship tables in SQL is to have something like so: For tables User and Data the relationship table would be called UserData User_Data or something similar (from here) What happens then if you need to have multiple relationships between User and Data, representing each in its own table? I have a site I'm working on where I have two primary items and multiple independent M-M relationships between them. I know I could just use a single relationship table and have a field which determines the relationship type, but I'm not sure whether this is a good solution. Assuming I don't go that route, what naming convention should I follow to work around my original problem?

  • [Flex] Modify components that is not included in the current state?

    - by user322896
    In Flex 4, is it possible to modify components that is not include in the current state? For example, I have labelA included in stateA, how do I change the label text in stateB? If I directly change the label text in stateB, I'll get an null reference error message. One workaround is to include labelA in all states, and set it to be invisible in states other than stateA. However, if the number of this kind of component goes too large, the work becomes tedious, and also I don't think it's reasonable to include unnecessary UI components in unrelated states. Is there better solution for this situation? Thanks! Regards

  • Make jQuery AJAX have a non-javascript (non-ajax) fallback?

    - by DrAgonmoray
    I've gotten a fair amount of work done on my latest project, but I've realized there's a bit of a problem: If you don't have a Javascript-enabled browser, you can't submit any forms because every form uses AJAX to submit it. My question to you all: How can I implement some sort of "fallback" so that if they don't have Javascript enabled, they can still submit the form. Currently I have a banner along the header that says "For the optimal (and by "optimal," we mean "actually working") experience, please enable Javascript in your browser." but that seems like less than the optimal solution. Thanks!

  • How to achieve Bottom Align floated div that sizes to it's container.

    - by Davy8
    How can I achieve the following layout? Specifically the positioning of Image and DIV I've found that unless I set a specific width for the Div, it will just go on to the next line and take up the full width of the container. Additionally aligning it relative to the bottom of the image is giving me trouble. Currently they're both float:left Edit: The two solutions so far work if the image is a constant width which I guess I could work with, but it's going in a Wordpress theme for an author's profile page and it's possible that images would have slightly variable widths. Is there a solution that would have the Div right next to the image (minus padding) regardless of how wide or narrow the image is? Basically having the div adjust its width to accommodate the image width.

  • How to get it working in O(n)?

    - by evermean
    I came across an interview task/question that really got me thinking ... so here it goes: You have an array A[N] of N numbers. You have to compose an array Output[N] such that Output[i] will be equal to multiplication of all the elements of A[N] except A[i]. For example Output[0] will be multiplication of A[1] to A[N-1] and Output[1] will be multiplication of A[0] and from A[2] to A[N-1]. Solve it without division operator and in O(n). I really tried to come up with a solution but I always end up with a complexity of O(n^2). Perhaps the is anyone smarter than me who can tell me an algorithm that works in O(n) or at least give me a hint...

  • How to automatically reflect the new Updates (on Database) to User Pages

    - by user296436
    I am trying to create a new Notice Alert using PHP and Javascript. Suppose that a 100 users are currently logged into to the Online Notice Board Application and any One user posts a new notice. I want an immediate alert signal on all the users screen. I know, that the simplest way of doing it is to constantly Ping the server but I don't want to do it as it will slow down the server. Moreover, I am on a shared host. So I don't have access to any Socket Port. That means, I cannot establish any direct Socket Communication Channel from the Server to the User Machine. Can any one suggest me some other solution to this kind of problems???
