  • How to split this string and identify first sentence after last '*'?

    - by DaveDev
    I have to get a quick demo for a client, so this is a bit hacky. Please don't flame me too much! :-) I'm getting a string similar to the following back from the database: The object of the following is to do: * blah 1 * blah 2 * blah 3 * blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. I need to format this so that each * represents a bullet point, and the sentence after the last * goes onto a new line, ideally as follows: The object of the following is to do: blah 1 (StackOverflow wants to add bullet points here, but I just need '*') blah 2 blah 3 blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. It's easy enough to split the string by the * character and replace that with <br /> *. I'm using the following for that: string description = GetDescription(); description = description.Replace("*", "<br />*"); // it's going onto a web page. but the result this gives me is: The object of the following is to do: blah 1 blah 2 blah 3 blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. I'm having a bit of difficulty identifying the fist sentence after the last '*' so I can put a break there too. Can somebody show me how to do this?

  • How do I introspect on a SQL Server?

    - by MetaHyperBolic
    I have a server with a vendor application which is heavily database-reliant. I need to make some minor changes to the data in a few tables in the database in an automated fashion. Just INSERTs and UPDATEs, nothing fancy. Vendors being vendors, I can never be quite sure when they change the schema of a database during upgrade. To that end, how do I ask the SQL server, in some scriptable fashion, "Hey, does this table still exist? Yeah, cool, okay, but does it have this column? What's the data type and size on that? Is it nullable? Could you give me a list of tables? In this table, could you give me a list of columns? Any primary keys there?" I do not need to do this for the whole schema, only part of it, just a quick check of the database before I launch into things. We have Microsoft SQL Server 2005 on it currently, but it might easily move to Microsoft SQL Server 2008. I am probably not using the correct terminology when searching. I do know that ORM is not only too much overhead for this sort of thing, but also that I have no chance of pitching it to my coworkers.

  • How to parse mathematical expressions involving parentheses

    - by Rob P.
    Please forgive my title, I really don't know how to phrase it better. This isn't a school assignment or anything, but I realize it's a mostly academic question. But, what I've been struggling to do is parse 'math' text and come up with an answer. For Example - I can figure out how to parse '5 + 5' or '3 * 5' - but I fail when I try to correctly chain operations together. (5 + 5) * 3 It's mostly just bugging me that I can't figure it out. If anyone can point me in a direction, I'd really appreciate it. EDIT Thanks for all of the quick responses. I'm sorry I didn't do a better job of explaining. First - I'm not using regular expressions. I also know there are already libraries available that will take, as a string, a mathematical expression and return the correct value. So, I'm mostly looking at this because, sadly, I don't "get it". Second - What I've tried doing (is probably misguided) but I was counting '(' and ')' and evaluating the deepest items first. In simple examples, this worked; but my code is not pretty and more complicated stuff crashes. When I 'calculated' the lowest level, I was modifying the string. So... (5 + 5) * 3 Would turn into 10 * 3 Which would then evaluate to 30 But it just felt 'wrong'. I hope that helps clarify things. I'll certainly check out the links provided.

  • Testing Web Application: "Mirror" ad-hoc testing in another window

    - by Narcissus
    I don't even really know if the title is the best way to explain what I'm trying to do, but anyway... We have a web app that is being ported to a number of DB backends via MDB2. Our unit tests are pretty lacking at the moment, but our internal users are pretty good at knowing what to test to see if things are broken. What I'm 'imagining' is a browser plug in (don't really care which browser it is for) or a similar system that essentially takes every event from one window and 'mirrors' it in the other browser/s. The reason I'd like this is so that I can have various installations that use different DB backends, and have the user open a window/tab to each installation. From there, however, I'd like them to be able to 'work' in one window and have that 'work' I occur at the same time in each of the 'cloned' windows. From there, they should be able to do some quick eyeballing of the information that comes back, without having to worry about timing differences and so (very much). I know it's a big ask, but I figure if anyone knows of a solution, I'd find it here... Any thoughts?

  • Anyone Experiencing Slow Builds With VS2010?

    - by MrKWatkins
    Hi, We've recently upgraded to the final release of VS2010 and are experiencing very slow build times compared to the same code under 2008. I was wondering if anyone else is experiencing the same so I can work out whether it's just our environment or not? A few details: Using VS2010 Ultimate on Windows 7 with fairly beefy machines, talking to TFS 2010. The solution has been upgraded from VS2008 but still builds against .NET 3.5 and ASP.NET MVC 1.0. It doesn't seem to be the compilation itself taking long but something else in the build process. This is because even projects that are up to date and don't need compiling are taking a few seconds or so to process. It's not due to an Visual Studio addin because a couple guys in the team haven't installed any. The first build after loading VS2010 is pretty quick, then they seem to slow down over time. For example on of the projects in my solution just took 00:00:00.08 to process after a restart. (The project was up to date and didn't need compiling) I then immediately hit rebuild and it jumps to 00:00:01.33. We're also experiencing the problem with another solution that uses .NET 4.0 that was building perfectly fine under VS2010 RC. There are no build events or anything like that I can blame, just straightforward assembly builds. The IDE is not very responsive during the slow builds. Anyone else has similar problems? Update: It looks like the resolving assembly references is taking a long time. Looking at the MSBuild diagnostic output or the example above the first build has 30ms for ResolveAssemblyReferences, the second build has 800ms. Subsequent builds seem to be taking longer copying stuff around, e.g. CopyFilesToOutputDirectory jumps from 1ms to 27ms.

  • Best ways to format LINQ queries.

    - by Aren B
    Before you ignore / vote-to-close this question, I consider this a valid question to ask because code clarity is an important topic of discussion, it's essential to writing maintainable code and I would greatly appreciate answers from those who have come across this before. I've recently run into this problem, LINQ queries can get pretty nasty real quick because of the large amount of nesting. Below are some examples of the differences in formatting that I've come up with (for the same relatively non-complex query) No Formatting var allInventory = system.InventorySources.Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }).GroupBy(i => i.Region, i => i.Inventory); Elevated Formatting var allInventory = system.InventorySources .Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy( i => i.Region, i => i.Inventory); Block Formatting var allInventory = system.InventorySources .Select( src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy( i => i.Region, i => i.Inventory ); List Formatting var allInventory = system.InventorySources .Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy(i => i.Region, i => i.Inventory); I want to come up with a standard for linq formatting so that it maximizes readability & understanding and looks clean and professional. So far I can't decide so I turn the question to the professionals here.

  • Need to sort 3 arrays by one key array

    - by jeff6461
    I am trying to get 3 arrays sorted by one key array in objective c for the iphone, here is a example to help out... Array 1 Array 2 Array 3 Array 4 1 15 21 7 3 12 8 9 6 7 8 0 2 3 4 8 When sorted i want this to look like Array 1 Array 2 Array 3 Array 4 1 15 21 7 2 3 4 8 3 12 8 9 6 7 8 0 So array 2,3,4 are moving with Array 1 when sorted. Currently i am using a bubble sort to do this but it lags so bad that it crashes by app. The code i am using to do this is int flag = 0; int i = 0; int temp = 0; do { flag=1; for(i = 0; i < distancenumber; i++) { if(distance[i] > distance[i+1]) { temp = distance[i]; distance[i]=distance[i + 1]; distance[i + 1]=temp; temp = FlowerarrayNumber[i]; FlowerarrayNumber[i] = FlowerarrayNumber[i+1]; FlowerarrayNumber[i + 1] = temp; temp = BeearrayNumber[i]; BeearrayNumber[i] = BeearrayNumber[i + 1]; BeearrayNumber[i + 1] = temp; flag=0; } } }while (flag==0); where distance number is the amount of elements in all of the arrays, distance is array 1 or my key array. and the other 2 are getting sorted. If anyone can help me get a merge sort(or something faster, it is running on a iPhone so it needs to be quick and light) to do this that would be great i cannot figure out how the recursion works in this method and so having a hard time to get the code to work. Any help would be greatly appreciated

  • Consecutive calls/evaulations in a form?

    - by Dave
    Hey guys, simple question... Working with XLISP to write a program, but I've seemed to run into a simple fundamental problem that I can't seem to work around: perhaps someone has a quick fix. I'm trying to write an if statement who's then-clause evaluates multiple forms and returns the value of the last. In example: (setq POSITION 'DINING-ROOM) (defun LOOK (DIRECTION ROOM) ... ) (defun SETPOS (ROOM) ... ) (defun WHERE () ... ) (defun MOVE (DIRECTION) (if (not(equal nil (LOOK DIRECTION POSITION))) ; If there is a room in that direction ( ; Then-block: Go to that room. Return where you are. (SETPOS (LOOK DIRECTION ROOM)) (WHERE) ) ( ; Else-block: Return error (list 'CANT 'GO 'THERE) ) ) The logical equivalent intended is: function Move (Direction) { if(Look(Direction, Room) != null) { SetPos(Look(Direction,Room)); return Where(); } else { return "Can't go there"; } } (Apologies for the poor web-formatting.) The problem I have is with: ( (SETPOS (LOOK DIRECTION ROOM)) (WHERE) ) I simply want to return the evaluation of WHERE, but I need to execute the SETPOS function first. XLISP doesn't like the extra parentheses: if I remove the outer set, my WHERE list becomes my else (I don't want that). If I remove the sets around SETPOS and WHERE, it treats WHERE like an argument for SETPOS; I also don't want that. So, how do I simply evaluate the first, then the second and then return the values of the last evaluated?

  • Mgmt wants to re-title my position: Any help...? [closed]

    - by JohnFlyTN
    Management here wants to re-title my position, since I'm doing quite a bit of different work than was originally planned. They want my input. After a quick glance over my skill set and job duties, what would we need to describe this position as? I'll just list things I'm at least proficient in, I will not list things I have a passing knowledge of. About me : ~10 years software development. Languages : C, C++, Perl, PHP, C#, TCL, Unix shell scripting, SQL (TSQL, PLSQL) Systems : MS-Dos, Windows 3.1 to 7 for client, NT 4 to 2008 for server, OS/2, IBM MVS & z/OS, Linux ( multiple distros), AIX Current position: I do all sorts of in-house software. The range is single user apps to large systems spanning multiple OS's. One of the larger projects I've designed and coded is about 100k lines of C#, and a database where I have been the sole designer and maintainer. I have near total freedom to design as I see fit, restraints are usually budgetary. Skills required to replace me in my current role: Windows and Unix admin, Database design, .NET up to 3.5 (C#, ASP.NET), C++, Perl, good skills in designing large and efficient data processing systems. Given this small level of information what would you see this as being titled? (is more information required to render a decision?)

  • What is the fastest (to access) struct-like object in Python?

    - by DNS
    I'm optimizing some code whose main bottleneck is running through and accessing a very large list of struct-like objects. Currently I'm using namedtuples, for readability. But some quick benchmarking using 'timeit' shows that this is really the wrong way to go where performance is a factor: Named tuple with a, b, c: >>> timeit("z = a.c", "from __main__ import a") 0.38655471766332994 Class using __slots__, with a, b, c: >>> timeit("z = b.c", "from __main__ import b") 0.14527461047146062 Dictionary with keys a, b, c: >>> timeit("z = c['c']", "from __main__ import c") 0.11588272541098377 Tuple with three values, using a constant key: >>> timeit("z = d[2]", "from __main__ import d") 0.11106188992948773 List with three values, using a constant key: >>> timeit("z = e[2]", "from __main__ import e") 0.086038238242508669 Tuple with three values, using a local key: >>> timeit("z = d[key]", "from __main__ import d, key") 0.11187358437882722 List with three values, using a local key: >>> timeit("z = e[key]", "from __main__ import e, key") 0.088604143037173344 First of all, is there anything about these little timeit tests that would render them invalid? I ran each several times, to make sure no random system event had thrown them off, and the results were almost identical. It would appear that dictionaries offer the best balance between performance and readability, with classes coming in second. This is unfortunate, since, for my purposes, I also need the object to be sequence-like; hence my choice of namedtuple. Lists are substantially faster, but constant keys are unmaintainable; I'd have to create a bunch of index-constants, i.e. KEY_1 = 1, KEY_2 = 2, etc. which is also not ideal. Am I stuck with these choices, or is there an alternative that I've missed?

  • How do I daemonize an arbitrary script in unix?

    - by dreeves
    I'd like a daemonizer that can turn an arbitrary, generic script or command into a daemon. There are two common cases I'd like to deal with: I have a script that should run forever. If it ever dies (or on reboot), restart it. Don't let there ever be two copies running at once (detect if a copy is already running and don't launch it in that case). I have a simple script or command line command that I'd like to keep executing repeatedly forever (with a short pause between runs). Again, don't allow two copies of the script to ever be running at once. Of course it's trivial to write a "while(true)" loop around the script in case 2 and then apply a solution for case 1, but a more general solution will just solve case 2 directly since that applies to the script in case 1 as well (you may just want a shorter or no pause if the script is not intended to ever die (of course if the script really does never die then the pause doesn't actually matter)). Note that the solution should not involve, say, adding file-locking code or PID recording to the existing scripts. More specifically, I'd like a program "daemonize" that I can run like % daemonize myscript arg1 arg2 or, for example, % daemonize 'echo `date` >> /tmp/times.txt' which would keep a growing list of dates appended to times.txt. (Note that if the argument(s) to daemonize is a script that runs forever as in case 1 above, then daemonize will still do the right thing, restarting it when necessary.) I could then put a command like above in my .login and/or cron it hourly or minutely (depending on how worried I was about it dying unexpectedly). NB: The daemonize script will need to remember the command string it is daemonizing so that if the same command string is daemonized again it does not launch a second copy. Also, the solution should ideally work on both OS X and linux but solutions for one or the other are welcome. (If I'm thinking of this all wrong or there are quick-and-dirty partial solutions, I'd love to hear that too.)

  • Why isn't this json/jquery function returning 10 results and why does it return 0 sometimes?

    - by Scarface
    Hey guys, quick question. I have a json function returning results from a php query but it is not working out because it seems to keep executing the query until all results are returned and sometimes returns 0 results (if I keep refreshing page, it returns 0 results sometimes). I want to limit results returned to 10 so I was wondering if anyone could point out the error of my code. Would really appreciate it. PS I am positive the query is returning the correct results and only 10 on its own. It just seems to be this one function that is not working out. SELECT time, user, comment FROM comments WHERE topic_id='$topic_id' ORDER BY time DESC LIMIT 10 var count=0; function prepare(response) { count++; var string = '<li class="list" id="list-'+count+'">' +'</li>'; return string; } $.getJSON(files+"comments.php?action=view&load=initial&topic_id="+topic_id+"&t=" + (new Date()), function(json) { if(json.length) { for(i=0; i < json.length; i++) { $('#shoutbox-list').prepend(prepare(json[i])); $('#list-' + count).fadeIn(1500); } var j = i-1; lastTime = json[j].time; } });

  • jQuery fade li elemet and cycle it when mouse hovered.

    - by Pennf0lio
    I'm trying to recreate an effect in jQuery, where an element(<li> <img>) will be cycled and has a fading effect when hovered. The '<li>' contains '<img>' (image screenshots). when the mouse is on top of element it will keep cycling all that are in '<ul>' with a fading effect. when the mouse is away it will stop cycling the list. I also want to add a pager where you can navigate to the list. My Existing Code: link text My Problem: The current code has some problem with the pagination, it added all images that can be seen on the code. instead of 1-8 only, it continued to add another 1-8 and another. Second problem is, It also start cycling and fading when the page loads. The cycling and fading should only be working when the mouse is on top of the element. I don't know if the 'Cycle Plugin' is really required on this approach, I wan't it to be minimal as much as possible. I just use 'Cycle Plugin' because it's a quick answer to my problem. The effect i'm trying to achieve: link text (WARNING: Contains some Pornography), Sorry of my example, I tried finding other alternative but no luck. Thanks and merry xmas!

  • Is there any library/software available that can give me useful measurements of image quality?

    - by Thor84no
    I realise measuring image quality in software is going to be really difficult, and I'm not looking for a quick-fix. Googling this is largely showing up research papers and discussions that go a bit over my head, so I was wondering if anyone in the SO community had any experience with doing any rough image quality assessment? I want to use this to scan a few thousand images and whittle it down to a few dozen images that are most likely of poor quality. I could then show these to a user and leave the rest to them. Obviously there are many metrics that can be a part of whether an image is of high/low quality, I'd be happy with anything that could take an image as an input and give some reasonable metrics to any of the basic image quality metrics like sharpness, dynamic range, noise, etc., leaving it up to my software to determine what's acceptable and what isn't. Some of the images are poor quality because they've been up-scaled drastically. If there isn't a way of getting metrics like I suggested above, is there any way to detect that an image has been up-scaled like this?

  • Utility to indexing a directory?

    - by achacha
    Here is what I am trying to do: I have a directory (with sub-directories) with source files, I need to index them so I can find files fast (find as I type) so I can open them for compare/analysis. I don't want it to scan the content, just filename index for quick lookup. I do this when trying to determine if a class exists in a given tree (we maintain directory trees for each release which has a lot of files) and sometimes I want to quickly check files to see how something was implemented, etc. Most of these directories are on remote servers (sometimes on the other side of the world) or on a VM (which is on a server far away), so I only want to read the directory trees once, which is why running find every time is way too slow and doing 'find . foo.txt' and then searching that is a bit tedious. It's kind of like how "Find Resource" works in eclipse after it indexes all files, but it's a bit of a chore to import/remove directories into eclipse every time. Eclipse is also very slow when dealing with remote volumes. Any suggestions are appreciated :)

  • What is the best (Windows) program launcher?

    - by AR
    One of the biggest general productivity boosters I've used is a good program launcher. I was a long-time user of SlickRun, and I've tried a few others. My current favorite is Executor - by far the best I've used. Other options: Executor: My current favorite Vista Start Menu: Pretty good, actually, but Executor is similar (binds to Win+Z) and much more flexible. Quicksilver: For Macs only, but it seems to be the gold standard against which most other launchers are measured. Google Desktop: Press Ctrl+Ctrl and it's a quick launcher! AutoHotKey: Much,much more than just a launcher - more than I need, really. SlickRun: simple and unobtrusive Launchy: Seems to be the launcher of choice for many StackOverflow users :) Colibri: "Type Ahead - Information at the tip of your wings". Quite a cool concept. Many, many others. Scott Hanselman outlines some more here. I realize that everyone will have their own preferences, but the question is: is there anything that really stands out in terms of speed, features, and especially productivity increase?

  • Delete on a very deep tree

    - by Kathoz
    I am building a suffix trie (unfortunately, no time to properly implement a suffix tree) for a 10 character set. The strings I wish to parse are going to be rather long (up to 1M characters). The tree is constructed without any problems, however, I run into some when I try to free the memory after being done with it. In particularly, if I set up my constructor and destructor to be as such (where CNode.child is a pointer to an array of 10 pointers to other CNodes, and count is a simple unsigned int): CNode::CNode(){ count = 0; child = new CNode* [10]; memset(child, 0, sizeof(CNode*) * 10); } CNode::~CNode(){ for (int i=0; i<10; i++) delete child[i]; } I get a stack overflow when trying to delete the root node. I might be wrong, but I am fairly certain that this is due to too many destructor calls (each destructor calls up to 10 other destructors). I know this is suboptimal both space, and time-wise, however, this is supposed to be a quick-and-dirty solution to a the repeated substring problem. tl;dr: how would one go about freeing the memory occupied by a very deep tree? Thank you for your time.

  • Looking for out-of-place directories in an SVN working copy?

    - by jthg
    An annoyance that I sometimes come across with SVN is the working copy getting corrupted by one of the .svn folders getting moved from its original location. It doesn't happen often if you're careful and use the proper tools for all moves and renames, but it still somehow happens from time to time. First, does anyone know if there's a good way to catch the problem before a commit is even done? Cruise control usually catches the problem, but there are plenty of cases it wouldn't catch. Second, is there a quick and easy way to check for out-of-place .svn folder if I suspect that there is one? I can definitely do it manually by deducing what directory is out of place based on the compiler errors or by diffing the working copy with another clean checkout. But, this seems like a problem that SVN can diagnose in a second by giving me a list of all directories whose parent directory in the working copy doesn't match its parent directory in the repository. There there some way to have SVN give me a list like that? Thanks.

  • Switching between 2 UINavigationControllers

    - by Smikey
    Hi all, I seem to have a problem switching between 2 UINavigationControllers, i.e. one which controls the main (selection) menu of my application, and the second which controls the main session (i.e. the user can't go back to the selection menu once they're started a new session). The first works just fine, but I get into trouble when trying to load the second. I have a class called GameViewController which contains the second UINavigationController instance. I set this up as usual, linking it as an IBOutlet to the delegate and setting up the NavController in the GameViewController.xib file with its 'Class' property pointing at GameScreenViewController (my main game screen), and its NIB Name property pointing to the GameScreenViewController nib file. I then create a new instance of GameViewController and load it. In IB, the navigation controller looks fine, with its View 'loaded from "GameScreenViewController"', however when the NavigationController is loaded in the game, it actually loads the GameViewController's UIWindow instance (just a blank window). I'm not sure how to make it load the Navigation Controller's view rather than its own window? Also, another quick question. When I load the second navigation controller from the first, which makes more sense to use: [self.view addSubview:gameViewController.view]; or [self presentModalViewController:gameViewController animated:YES]; Thanks for any help, much appreciated :D Michael

  • NullPointerException on Activity Testint Tutorial

    - by Bendik
    Hello, I am currently trying the activity testing tutorial (Found here), and have a problem. It seems that whenever I try to call something inside the UIThread, I get a java.lang.NullPointerException. public void testSpinnerUI() { mActivity.runOnUiThread( new Runnable() { public void run() { mSpinner.requestFocus(); } }); } This gives me: Incomplete: java.lang.NullPointerException and nothing else. I have tried this on two different samples now, with the same result. I tried with a try/catch clause around the mSpinner.requestFocus() call, and it seems that mSpinner is null inside the thread. I have set it properly up with the setUp() function found in the same sample, and a quick assertNotNull( mSpinner ) shows me that mSpinner is in fact not null after the setUp() function. What can be the cause of this? EDIT; ok, some more testing has been done. It seems that the application that is being tested resets between each test. This essentially makes me have to reinstantiate all variables between each test. Is this normal?

  • Events fired when you change the contents of a control in Silverlight

    - by nyxtom
    Assuming I change the contents of a control using a XamlReader and add the UIElement to the container of a control, what events are supposed to fire? There are times where the SizeChanged will fire, LayoutUpdated changing.. though there are other times where neither of these occur despite having changing the contents of a control. In my case, I am generating a thumbnail view of what's currently in view on a page. The user can change the content of the page and thus the thumbnail should update accordingly. Though, wiring to the LayoutUpdated, Loaded, SizeChanged aren't always reliable for when the contents have changed. I would just call my InvalidateThumbnail which uses a writeablebitmap, but it's too quick after setting the content and as a result I will get a blank thumbnail. At the moment, my hack (cringes) was to wait a few milliseconds before the UI is done rendering the actual new content and I can reliably create the thumbnail. I'd rather just trigger on an event every time though. Possible? What events should I look at? I've seen CompositeTarget.Rendering but that's not what I want.

  • How would you structure your workflow for a web application ?

    - by cx42net
    Hi ! When designing a web application (or something else), it's good to have a workflow, and it's better to have a well ordered one. Starting with this idea in mind, I'd like to know what is your process from having an idea to maintain this great working project. For me actually, the process is the following one : Having the idea Checking this project already exists, and how it works Describing on a paper its functionalities finding a good and adequate name for this (and checking the domain availability with WHOISMyProject) Making a quick layout of the project on a paper Designing the project (via TheGimp, Photoshop, etc) Making a complete mockup of each pages Developing a prototype of the client-side application (with false datas) Developing the server side Testing Making the documentation/help/faq Releasing the project Maintaining it. Would you change the order of some points ? add/remove some ? I would please to know how you do that. I'm looking to set up a perfect workflow in order to make my project become real in the best way possible. Thank you for your opinion !

  • lightbox dynamic image retrieval

    - by GSTAR
    I am constructing a lighbox gallery, currently experimenting with FancyBox (http://fancybox.net) and ColorBox (http://colorpowered.com/colorbox). By default you have to include a link to the large version of the image so that the Lightbox can display it. However, I am wanting to have the image link URLs pointing to a script rather than directly to the image file. So for example, instead of: <a href="mysite/images/myimage.jpg"> I want to do: <a href="mysite/photos/view/abc123"> The above URL points to a function: public function actionPhotos($view) { $photo=Photo::model()->find('name=:name', array(':name'=>$view)); if(!empty($photo)) { $user=$photo->user; $this->renderPartial('_photo', array('user'=>$user, 'photo'=>$photo, true)); } } At some point in the future the function will also update the view count of the image. Now this approach is working to an extent - most images load up but some do not load up (the lightbox gets displayed in a malformed state). I think the reason for this is because it is not processing the function quick enough. For example when I click the "next" button it needs to go to the URL, process the function and retreive/output the response. Does anybody know how I can get this working properly?
