  • Wrong Editing Controls Displayed in UITableView

    - by CJC
    Hi all, I'm having a strange problem with UITableView. When the user taps the Edit button, the tableview (which is a grouped view with multiple sections) is supposed to show delete buttons for each row--except for the final row in each section, which has a green add button. When a user taps the green button, a new row is inserted, but now the final row gets a delete button. Even stranger, that delete button ACTS like an add button. So it seems there's a drawing glitch, rather than a problem in assigning the correct style. (Extensive NSLogging shows that the last cell is getting the Insert editing style correctly.) I've tried setting setNeedsDisplay on the cell and the tableView, I've tried reloading that section/row/the entire table, but the issue persists. Any ideas on how to get UITableView to explicitly redraw the editing controls?

  • How do would you use jQuery's .each() to apply the same script to each element with the same class?

    - by derekmx271
    I have a with multiple cart items listed. I have a "x-men logo" looking remove button that I want to fade-in next to the item when the customer hovers over a cart item. I had no issue getting this to work when there is only one item in the list. However, when there are multiple items in the cart, the jQuery operates funky. It still does the fade in, but only when I hover over the last item in the cart, and of course all of the "remove X" images become visible. Argh... So i searched around and think the .each() is my savior. I have been trying to get it to work, with no luck. My script just breaks when I attempt to implement it. Anyone have any pointers on this *.each() thing and how to implement it into my script?* I have tried putting a cartItem.each(function(){ around the mouseEnter/mouseLeave events (and used some $(this) selectors to make it "make sense") and that didn't do anything. Tried some other things as well with no luck... Here is the HTML (Sorry, there's a lot): <ul id="head-cart-items"> <!-- Item #1 --> <li> <!-- Item #1 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=AFE&amp;f=Air_Intakes_Magnum_FORCE_Stage-1_PRO_5R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/AFE/Intakes/Air_Intakes/Magnum_FORCE_Stage-1_PRO_5R/19029">AFE Magnum FORCE Stage-1 PRO 5R Air Intakes</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$195.00</span> <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> <!-- Item #2 --> <li> <!-- Item #2 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=Exedy&amp;f=Clutch_Kits_Carbon-R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/Exedy/Clutch/Clutch_Kits/Carbon-R/19684">Exedy Carbon-R Clutch Kits</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$2,880.00</span> <!-- Here is my other Remove-X... --> <a class="remove-x" href='/cart//7806888'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> </ul> And here is the jQuery... $(document).ready(function(){ var removeX = $(".remove-x"); var cartItem = $(".head-cart-item"); // Start with an invisible X removeX.fadeTo(0,0); // When hovering over Cart Item cartItem.mouseenter(function(){ // Fade the X to 100% removeX.fadeTo("normal",1); // On mouseout, fade it back to 0% $(this).mouseleave(function(){ removeX.fadeTo("fast",0); }); }); }); If you didn't see it, here is the "X" I am trying to fade... <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> Thanks for the help in advance.

  • Manage build target variables in iphone project

    - by DougW
    We're transitioning to an automated build process for our iphone projects. These projects can be checked out by individual devs, in which case all the API URLs need to point to a certain path. There are also a variety of build environments, each with their own API root paths. I could probably add multiple, different build targets, and have each of them include a different URLs definition file, but this seems like a lot of upkeep and a bit overkill. Any best practices out there for swapping a few environmental variables for different build environments without much fuss?

  • Video chat application : Which technology to choose ?

    - by WarDoGG
    I have to undertake a project which is to make a video chat application. The video has to be streamed from one location and can be viewed by multiple people spread out over the globe. Performance is really an issue and a delay of more than 2-3 seconds is unacceptable. From what i gather, this can be done in Flex and also in JAVA. Any performance issues and caveats with a particular approach ? I would really like the pros to comment on this and guide me through. Will be very very helpful. Are there any open source libraries available for video recording in flash / JAVA which i can integrate into my app and customize according to my needs ?

  • efficiently compare two BitArrays of the same length

    - by BobTurbo
    How would I do this? I am trying to count when both arrays have the same value of TRUE/1 at the same index. As you can see, my code has multiple bitarrays and is looping through each one and comparing them with a comparisonArray with another loop. It doesn't seem to be very efficient and I need it to be. foreach (bitArrayTuple in bitarryList) { for (int i = 0; i < arrayLength; i++) if (bArrayTuple.Item2[i] && comparisonArray[i]) bitArrayTuple.Item1++; } where Item1 is the count and Item2 is a bitarray.

  • Flash Media Server dynamic file naming

    - by flying_tiger
    I'm trying to figure out most efficient/safe way to name recorded streams on FMS. The case is to get listing of recorded streams from the server (eg. rec_001, rec_002...) and dynamically add rec_003 filename to the new stream that is being recorded. I'm thinking about either using FMS File Object and put everything in array of files every time I start recording procedure or to create XML file that would serve as a database of file names. I'm searching for a solution efficient for MULTIPLE connections at a time and large amount of files. Which one of presented would be the best for this purpose? Or do you have any better suggestions of solving this problem?

  • class/lib for parallel donwloads on iphone

    - by lope
    Hi there! I need some class or lib that would allow me to run multiple parallel downloads. I didn't have luck finding any, do you guys know about something useful? I need to add new files to download dynamically, so something that only get initialized with urls at the beginning won't help me much. Any help would be greatly appreciated. I tried to create my own, but I had some problems with it. So I figured I would try to get something that is already done.

  • HELP!! Implementing a search to match the specified author and displaying a book by the specified publisher

    - by Brian
    Hey guys! So i'm having problems with my assignment. I successfully got it to run multiple last names by the author, but now, I need to find all books by author, which means searching the collection for all books that match the specified author and I also need to find all books by publisher, which displays a list of books by the specified publisher. How would I implement this? Would I use string or vector? Any help will be much appreciated!

  • overiding to_param of a nested attribute

    - by cbrulak
    I'm trying to create a perma link for a nested attribute. For example, look at the links for the answers in SO. I would like to do something similar in rails: I have Project model with multiple tasks and I would like to create a perma link to a task. The task can only viewed with the project, just like Q & A on SO. Ideally, i would do something like: task_helper.rb: def GetTaskURL project = Project.find(:project_id) return project_url(project,:html) + "#" + id end However, i get a method not found. So it seems the only way is to hard-code it: domain.com url + Projects/show/id.html#task.id Must be a better way?

  • Using nsIZipWriter or other to compress a string as a string?

    - by Daniel
    I need to be able to take a javascript string, compress it using any fast and available means and get back a binary string/blob. Background: The extension I'm developing needs to send various large content to my server. It does this conveniently by dynamically creating a form, adding fields to the form and posting it. Some of these fields are just too big bandwidth wise for multiple use. I'd like to be able to compress them before adding them and then maybe base64'ing them if the characters cause a problem in the message. Any ideas? I could use nsiZipWriter with temporary files on disk but that is quite ugly and probably sluggish.

  • Missing something with Reader monad - passing the damn thing around everywhere

    - by Richard Huxton
    Learning Haskell, managing syntax, have a rough grasp of what monads etc are about but I'm clearly missing something. In main I can read my config file, and supply it as runReader (somefunc) myEnv just fine. But somefunc doesn't need access to the myEnv the reader supplies, nor do the next couple in the chain. The function that needs something from myEnv is a tiny leaf function. So - how do I get access to the environment in a function without tagging all the intervening functions as (Reader Env)? That can't be right because otherwise you'd just pass myEnv around in the first place. And passing unused parameters through multiple levels of functions is just ugly (isn't it?). There are plenty of examples I can find on the net but they all seem to have only one level between runReader and accessing the environment.

  • No optimization causes wrong search result

    - by KailZhang
    I just took over our solr/lucene stuff from my ex-colleague. But there is a weird bug. If there is no optimization after dataimport, actually if there are multiple segment files, the search result then will be wrong. We are using a customized solr searchComponent. As far as I know about lucene, optimization is only optimization which could improve the speed of indexing and should not affect search result. I doubt this may be related to multithreading or unclosed searcher/reader or something. Anybody can help? Thank you.

  • Attributes passed to .build() dont show up in the query

    - by Sebastian
    Hi there guys! Hope your all enjoying your hollydays. Ive run into a pretty funny problem when trying to insert rows into a really really simple database table. The basic idea is pretty simple. The user selects one/multiple users in a multiselect which are supposed to be added to a group. This piece of code will insert a row into the user_group_relationships table, but the users id always @group = Group.find(params[:group_id]) params[:newMember][:users].each do |uid| # For debugging purposes. puts 'Uid:'+uid @rel = @group.user_group_relationships.build( :user_id => uid.to_i ) @rel.save end The user id always gets inserted as null even though it is clearly there. You can see the uid in this example is 5, so it should work. Uid:5 ... SQL (0.3ms) INSERT INTO "user_group_relationships" ("created_at", "group_id", "updated_at", "user_id") VALUES ('2010-12-27 14:03:24.331303', 2, '2010-12-27 14:03:24.331303', NULL) Any ideas why this fails?

  • How do I avoid nesting forms when offering inline editing of lists with checkboxes for mass updates.

    - by adam
    A lot of sites offer the ability to edit lists of items inline as well as allowing multiple items to be selected via checkboxes and have an action performed all at once e.g. delete, mark as spam etc. But how do you implement this without violating html rules. I need one form for the checkboxes with individual submit_tags for the mass actions. But after a user clicks on an item in the list, another form via Ajax will be inserted within the checkbox form. How do I avoid doing this? I'm using rails and jQuery.

  • Visual C++ 9 Linker file size limitation.

    - by Raindog
    It appears that the visual C++ 9 linker has a file allocation algorithm that doubles the size of the file every allocation, so you get 512mb, 1024mb, 2048mb, 4096mb. The problem is that it is using a library that cannot handle files larger 2048MB, and as such crashes with an error such as "cannot read file at is the disk full or write protected". Is there a way to bypass this limitation or otherwise replace the linker with something else that works? A bit of background, I have a code generator that generates a large number of files, ~15k cpp files, I've managed to reduce the number of files to something about 6k to get something that at least completes the linking process, I would like to be able to include all 15k without having to create multiple libs.

  • deleting a large number of rows from a table

    - by Azeem
    We have a requirement to delete rows in the order of millions from multiple tables as a batch job (note that we are not deleting all the rows, we are deleting based on a timestamp stored in an indexed column). Obviously a normal DELETE takes forever (because of logging, referential constraint checking etc.). I know in the LUW world, we have ALTER TABLE NOT LOGGED INITIALLY but I can't seem to find the an equivalent SQL statement for DB2 v8 z/OS. Any one has any ideas on how to do this really fast? Also, any ideas on how to avoid the referential checks when deleting the rows? Please let me know.

  • newline in Rackspace Cron Job email

    - by senloe
    I'm running backups against multiple databases hosted at Rackspace. This is working fine. The problem I'm running into is with the results email. I'm using Response.Write to write a message to the web page which is used for logging and is also consumed by the results mail sent out by the job. The problem is I can't seem to get newlines to appear between log messages. The logfile stored on the server is correct, but only the first newline shows up in the email. The mail is in Plain Text format so I tried using "\n" and System.Environment.Newline and neither work. I also tried using <br/> with no luck. Does anybody have any ideas?

  • Query to work out possible destinations on a set of routes using SQL Server 2008

    - by RobW
    I'm writing an application that models train routes, which are stored in the database table [TrainStop] as follows: RouteId StationCode StopIndex IsEnabled So a given route consists of several rows with the StopIndex indicating the order. The problem I am trying to solve is to say which stations a user can get to from a given starting station. This would be relatively straightforward BUT it is also possible to disable stops which means that a user cannot get to any destinations after that stop. It is also possible that multiple routes can share stations e.g.: Route 1: A, B, C, D, E Route2: P, Q, B, C, D, R So if a user is at B they can go to C, D, E and R but if station D is disabled they can get to C only. Solving this problem is fairly straightforward within C# but I am wondering whether it can be solved elegantly and efficiently within SQL? I'm struggling to find a way, for each route, to rule out stations past a row that is not enabled.

  • Creating a WCF Restful service, concurrency issues

    - by pmillio
    Hi i am in the process of creating a restful service with WCF, the service is likely to be consumed by at least 500 people at any given time. What settings would i need to set in order to deal with this. Please give me any points and tips, thanks. Here is a sample of what i have so far; [ServiceBehavior(IncludeExceptionDetailInFaults = true, InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)] And this is an example of a method being called; public UsersAPI getUserInfo(string UserID) { UsersAPI users = new UsersAPI(int.Parse(UserID)); return users; } [OperationContract] [WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, UriTemplate = "User/{UserID}")] [WebHelp(Comment = "This returns a users info.")] UsersAPI getUserInfo(string UserID);

  • Excel + Web Data

    - by user348152
    I've spent hours scouring the net for anything to do with VBA calling data from the web in excel and nothing provides a tutorial on how to do so, only complicated examples un-related to what I want to do. I want to pull data from either a .html or .xml site, doesn't matter, via Excel and find specific points in that data. I can find specific points but don't know how to get the data or scroll through multiple lines. I've done this exact sort of thing in mIRC (sort of C code). http://eve-central.com/home/quicklook.html?typeid=438 http://api.eve-central.com/api/quicklook?typeid=438 Those are two examples, using roughly the same data I'd like to retrieve. It'd be FAR more specific with at most 100 or so different values. I'd like to be TAUGHT how to do it, not given the code to do it, or if you must explain each part with comments in-depth please. Thanks Nick

  • Faking a Single Address Space

    - by dsimcha
    I have a large scientific computing task that parallelizes very well with SMP, but at too fine grained a level to be easily parallelized via explicit message passing. I'd like to parallelize it across address spaces and physical machines. Is it feasible to create a scheduler that would parallelize already multithreaded code across multiple physical computers under the following conditions: The code is already multithreaded and can scale pretty well on SMP configurations. The fact that not all of the threads are running in the same address space or on the same physical machine must be transparent to the program, even if this comes at a significant performance penalty in some use cases. You may assume that all of the physical machines involved are running operating systems and CPU architectures that are binary compatible. Things like locks and atomic operations may be slow (having network latency to deal with and all) but must "just work".

  • What is the recommended way to split messages in send pipelines?

    - by ToxicAvenger
    I need to split a bizTalk message in the send pipeline. This is easy with disassemblers in receive pipelines, but doesn't work in send pipelines (makes sense). So what is the recommended way to do it? The only easy way to do it is to write the outbound message to file, then reprocess it using a receive pipeline with a disassembler, and then send the generated messages through a outbound pipeline. Honestly, I don't need the additional roundtrip through the message box, but I don't want to create a custom send adapter. Any other suggestions? Any easy way to save messages with multiple parts using the ootb file adapter?
