• Codeigniter pre_system hook for DB driven dynamic controller selection - best approach?

  - by Andy

  Although I can tentatively see a solution to this, I was wondering if there may be a glaringly obvious simpler approach. My aim is to use the first segment of a given URI to query the DB as to which controller should be run. I assume I would have to reform the URI with the resultant controller name in segment 1, then allow the system to continue processing as normal (hence a pre_system hook). Although not essential I would also like to hold a couple of other variables from the same DB request to be used later in the call stack, and assume this would have to be done using global variables? Any better suggestions would be gladly received. Thanks.

• How do I place an image centered in a DIV and text to the right? Overflow problems

  - by user2218041

  I have a div container where I want to put in a centered image and a small description to the right. The specifications are: The image should have a bottom margin of 35px. The image should always show fully on the screen, so it resizes when the screen does. It should have the biggest size possible, but never be cropped and never use scrollbars. The image should be centered with respect to the container, with the text showing on the right margin. The text should be left-aligned horizontally, center-aligned vertically and have a 30px separation from the image. I've tried using a table in the container and using divs, but I can't find a clean solution. I can show you the non-working code I've tried on request.

• Which messaging services can BlackBerry apps integrate with?

  - by humble coffee

  I'm in charge of having a BlackBerry app developed that translates the contents of a message from one language to another. So the aim would be to have a button at the bottom of a received message which says 'translate this'. I've heard that this kind of thing is possible using J2ME plus the native BlackBerry API. Can this be done for all kinds of messanging features on the Blackberry, or just some? ie I'm thinking SMS, email and BB messages. Secondly, given that the translation itself is done via a web request, I feel like this should be a fairly lightweight application. Would anyone care to hazard a guess how long it might take an experienced contractor to develop such an app?

• Haskell: Constrain function on type Double to only work with Integers

  - by thurn

  Suppose I'm writing a function that takes a list of integers and returns only those integers in the list that are less than 5.2. I might do something like this: belowThreshold = filter (< 5.2) Easy enough, right? But now I want to constrain this function to only work with input lists of type [Int] for design reasons of my own. This seems like a reasonable request. Alas, no. A declaration that constraints the types as so: belowThreshold :: [Integer] -> [Integer] belowThreshold = filter (< 5.2) Causes a type error. So what's the story here? Why does doing filter (< 5.2) seem to convert my input list into Doubles? How can I make a version of this function that only accepts integer lists and only returns integer lists? Why does the type system hate me?

• PHP CURL works fine from localhost not from server

  - by Joby Joseph

  I have 2 servers, srv1 and srv2. All client sites are stored in srv2 and all authentication details are stored in srv1. Each time a client site is loaded, the site in srv2 sends a curl request to srv1 to validate. I am always getting bool(false) when I print the curl response using var_dump. But if I am requesting for validation from my local wamp installation(localhost) it is perfectly returning the response. According to my understanding srv2 is blocking srv1 ip or something like that. Any help or suggestions will be greatly appreciated. The solution is really urgent as all my clients are stuck with invalid authorization message. Edit: Now when i tested curl in srv2 is working fine i think. Because I am able to fetch other websites without any trouble. But I am not able to fetch data from srv1. I can view a page from srv1 through browser url but not through curl.

• How to read a complex view model on POST?

  - by Interfector

  Hello, I have an user view model that has the following properties: public User user; public List<Language> Languages; I send the above model to the view and use html helpers to build the form, so I end up with something like: <form action="/Users/Edit/5" method="post"><input id="user_UserId" name="user.UserId" type="hidden" value="5" /> First Name Last Name Email Language - en en Now, I try to read the POST in something that initially was something like : [AcceptVerbs( HttpVerbs.Post )] public ActionResult Edit( int UserId, FormCollection form ) { and cannot get the user.UserId variable, user.FirstName variable etc. Any idea what needs to be done to be able to read this kind of POST request. I'm kind of reluctant to modifying my ViewModel as it is very simple and easy to maintain as it is. Thank you.

• Inconsistent Session data from IE - cached sessions???

  - by pedalpete

  I'm trying to prevent some basic click-fraud on my site, and am building links based on session time data. Everything works in FF, but in IE the information I'm storing in the session is somehow being changed. When I load up the main page, I set my session variables like this session_start(); $_SESSION['time']=$time(); I'm out putting the session value into the page, so I get something like 1275512393. When the user clicks on a link, I send an ajax request, and that page is returning the session which I am putting into an alert. session_start(); echo $_SESSION['time']; die(); The alert is returning 1275512422. Only in IE is the $_SESSION['time'] being returned different from the original $_SESSION['time'] It doesn't appear that this is a caching issue, as the times are always VERY near each other, and the second one is always after the first, but I'm not positive.

• Does it mean JVM Suspended?

  - by Joe.wang

  When my application run . I got a message says : Ping: Timed out waiting for signal from JVM. The JVM was launched with debug options so this may be because the JVM is currently suspended by a debugger. Any future timeouts during this JVM invocation will be silently ignored. What does that mean? It seems it will block any web request from outside? because when I upload a file to it, it failed. help me .

• A new Rails idea in views and no more controller. maybe better maybe worse, i need help if this is t

  - by Totty

  Hy, I was thinking that all my website will have use of cells, using the known plugin cell for rails, so this is my idea: A table that contains 3 fields: id, view_name and layout. the layout will be a serialized hash. When a request is made, the layout field is requested and then in the view, default layout, will be unserialized the layout var, that looks like this: @layout[:sidecol][:gallery] = {... some params for it...}; @layout[:maincol][:comments] = {..params...}; In the <% #ruby code to render the cells in the @layout[:sidecol] % will be some ruby code that will loop over the @layout[:sidecol] and render all cells in it. the same occurs in the maincol div. What do you think? Positive in my opinion: More modular controller is used only for post easy change of structure easier to implement some kind of traking to see diferences on what layout is better or not. Negative: not found yet

• Post-back + Page Refresh. Post/Redirect/Get pattern alternatives?

  - by Andrew Florko

  When user posts back a web form and then tries to refresh the page - dialog "would you like to resend information" pops up (Opera works silently though). To avoid this we can redirect browser to the page we'd like to show after postback. Now, when user refreshes the page, he duplicates get-request and no pop-ups. Everything is ok but post/redirect/get approach requires additional roundtrip. Is there better alternatives. Send form data with ajax aynchronously, for example? Thank you in advance!

• Are global comment systems a privacy concern?

  - by Stefano Borini

  I more and more see these global login-once comment-everywhere systems on every page. I didn't do my homework of tinkering debugging and search before asking, so my question is as follows: You login on site A and leave a comment. Now you go on site B, which uses the same global comment system. At the bottom of the page a request form with your name and data appears for you to add a comment on B page. You don't leave any comment and browse away. Does the global-comment provider get information about the fact that you visited page B, even if you don't leave any comment ? I will dig into the code as soon as I have time, but in the meanwhile I would like to ask your insights on this regard.

• How can I close my software in a save way?

  - by Roman

  Up to now I used my application as a stand alone product. So, when user pressed "Stop" button I called System.exit(0); and it was fine. Now my application will be called (in a programmatic way) from another program. So, I afraid that System.exit(0); will kill not only my process but also the external software which started my program. So, what is the correct way to shutdown my application if a corresponding request from an external software is received? My application is an GUI application. So, I want to close the window but I also want to close all processes performed by my program. ADDED: To be more specific, I want to close all threads started by my program. My program does not start any OS process or any other program.

• Does a servlet knows the encoding of the sent form that specified using http-equiv?

  - by Daziplqa

  Does a servlet knows the encoding of the sent form that specified using http-equiv? When I specify an encoding of a POSTed form using http-equiv like that: <HTML> <head> <meta http-equiv='Content-Type' content='text/html; charset=gb2312'/> </head> <BODY > <form name="form" method="post" > <input type="text" name="v_rcvname" value="????"> </form> </BODY> </HTML> And then at the servlet I use the method, request.getCharacterEncoding() I got null ! So, Is there a way that I can tell the server that I am encoding the data in some char encoding??

• SSRS and cached reports

  - by Tabloo Quijico

  Hi, I'm opening an SSRS2008 report using the http://server/reportserver/... syntax, outputting directly a PDF copy. This report has several parameters. The problem is that, despite making changes to the report, and clearing the browser's temporary files cache.. if I request the same report (i.e. same parameters) - the old report is returned. In the report execution properties, I have "Always run this report with the most recent data" and "Do not cache temporary copies of this report" selected. It's not just a case of caching data, but the entire report (including formatting, e.g. I deleted a page from the report yet it was still being shown...) and as I haven't specifically chosen to perform any caching I'm a little concerned and clearly don't fully understand what's going on! Any tips?

• Delete/move a UITableView row that's attached to a web service.

  - by Kevin L.

  Deleting or moving rows for a UITableView that is backed with local data (e.g., NSArray) is easy and instantaneous: Remove the value from the array. Call deleteRowsAtIndexPaths:withRowAnimation:. Profit! But my table view communicates with a web service, which means once the "Delete" button on that row gets tapped, I have to forward a request on to the server (via ASIHTTPRequest, of course), get the response, and then tell the table view to run its little delete-row animation, all with a few seconds of latency in between. From a high-level, what's the best way to do that? Throw some callback selector into ASIHTTPRequest's userInfo dictionary? KVO? Bonus points for some nice UI touch, like some kind of spinner on the soon-to-be-deleted cell.

• How do I determine the video file size on youtube in Java?

  - by user1753343

  I am using the youtube-API to gather different information about videos. The only missing attribute until now is size. The API itself doesn't provide any functionality. I googled, but didn't found any solution. Indirect way My next idea was to get the path to the video-file itself and make a get-request. In the response-headers I could check for the file size. So I searched for "video / download / youtube / java". Some time ago youtube used get_video_info but this doesn't work today. I also found an application called JavaYoutubeDownloader but it seems VERY complicated for just getting the file size and it doesn't work either (just prints finish, without downloading anything). So is there a way to get the filesize of a video on youtube by using Java? If not, what would be a practical solution for this problem (a list of video_ids exists)?

• Advice on creating simple web service

  Hi all, I want to build simple SOAP web service. So far I've only worked with existing SOAP/Rest services. And now I'd like to create my own, simple one for starters. For example create simple hello + string web service where I provide the string in request from SOAP ui or similar tool. I have Jboss server installed already, what is the "simplest" possible way to achieve this? I realize I need interface, interfaceImpl, and a wsdl file(generated possibly). Does anyone have some useful advice for me ? thank you

• php most memory efficient way to return files

  - by bumperbox

  so i have a bunch of files, some can be up to 30-40mb and i want to use php to handle security of the files, so i can control who has access to them that means i have a script sort of like this rough example $has_permission = check_database_for_permission($user, filename); if ($has_permission) { header('Content-Type: image/jpeg'); readfile ($filename); exit; } else { // return 401 error } i would hate for every request to load the full file into memory, as it would soon chew up all the memory on my server with a few simultaneous requests so a couple of questions is readfile the most memory efficient way of doing this? is there some better method of achieving the same outcome, that i am overlooking? server: apache/php5 thanks

• Browser, upload large file

  - by Mike

  I'm looking for a way to allow a user to upload a large file (~1gb) to my unix server using a web page and browser. There are a lot of examples that illustrate how to do this with a traditional post request, however this doesn't seem like a good idea when the file is this large. I'm looking for recommendations on the best approach. Bonus points if the method includes a way of providing progress information to the user. For now security is not a major concern, as most users who will be using the service can be trusted. We can also assume that the connection between client and host will not be interrupted (or if it is they have to start over).
