  • Ruby on Rails redirect_to not functioning in IF statement?

    - by Hard-Boiled Wonderland
    Hi, I am redirecting a POST request to ensure the URL is correct along with other things. The redirect worked fine before I added in the if statements for town below: if !params[:address].blank? town = Town.find(:all, :conditions => ["name = ?", params[:address]]) @towns = town if !town.blank? redirect_to '/town/' + params[:address] else @town_invalid = 'test' end end end I am sure it is something simple and that I simply cannot see it. Also if you see any glaring errors or code mishaps let me know as I am just starting out. EDIT: I should mention this is what I get back from Safari when a real town is entered: Safari can’t open the page.Safari can’t open the page “http://localhost:3000/” because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again. Thanks!

  • Thread and two dimensional array in objective C?

    - by mactonny
    Hey, guys, I am just starting to wrap my head around objective C and I am doing a little project on Iphone. And I just encountered a weird problem. I had to deal with images in my program so I have a lot local variables declared like temp[width][height]. If I am not using NSThread to perform image processing, it works all fine. However, if I use NSThread, it'll keep giving me EXC_BAD_ACCESS on whenever I try to access a 2-D array declared like temp[widht][height]. So I have to allocate memory from heap in order to have a 2-D array. That'll solve the problem but I still don't get it. My first thought would be stack over flow, but it worked all fine with one thread. I just don't get it.

  • Writing a Windows NT subsystem

    - by Niten
    I'd like to try writing my own minimal NT subsystem on Windows 7 for purely educational purposes -- something like a bare-bones equivalent of the posix.exe in Microsoft's Subsystem for Unix-based Applications. But I can't seem to find any public documentation on this topic. What API does a subsystem need to implement? How does it get registered with Windows? How does the subsystem image need to be built (what flags need to be set in the PE header, etc.)? I'd most like to find a book or web site with an overview of the entire subject, or even the source code for a "hello world" NT subsystem that someone else has written. But anything at all would be appreciated if you can point me in the right direction here...

  • How to capture screen with timer using C#?

    - by ankush
    This is a Windows application using C#. I want to capture a screen shot with a timer. The timer is set to a 5000 ms interval. As the timer is started, the desktop screen should be captured with the source window caption. try { System.Windows.Forms.Timer timer = new System.Windows.Forms.Timer(); timer.Tick += new EventHandler(timer2_Tick); timer.Interval = (100) * (50); timer.Enabled = true; timer.Start(); ScreenShots sc = new ScreenShots(); sc.pictureBox1.Image = system_serveillance.CaptureScreen.GetDesktopImage(); while(sc.pictureBox1.Image != null) { sc.pictureBox1.Image.Save("s"+".jpg", System.Drawing.Imaging.ImageFormat.Jpeg); sc.pictureBox1.Image = null; } This code is not working properly. How can I make it work?

  • Message Driven Bean with Java Message Queue down

    - by Rafa de Castro
    I have the following problem deploying my application. It uses JMS and a remote openMQ for communication between servers. The problem is that the connection is not fully reliable so it can be up or down. For reconnecting I set the jms reconnect glassfish property so it reconnects if at some moment the connection gets lost. The problem arises when i try to deploy the application and there is no connection. It looks like it keeps retrying the connection but the application does not finish deployment until connection is available. Is it possible to configure it in any way that the deployment continues even if there is no connection and keeps retrying until there is connection available? Thanks a lot.

  • Flex URLRequest Timeout

    - by MooCow
    I have a Flex program that gets a JSON array from a PHP script. The PHP script doesn't contain just a simple JSON array but it grabs data from Activecollab and do some work on the data before encoding the data. The first test involve a small JSON array that took a short time to encode by PHP. However, when I try to scale up the test, the Flash movie will crash trying to load the JSON data from PHP. There's no code difference between the tests, just the amount of data and amount of time it takes PHP to encode. Am I looking at a memory problem or a time out problem? PS: When I call the PHP script in Firefox, it doesn't time out and still return a JSON array. It just took awhile to return the array.

  • dll woes c# noob

    - by Chin
    Hi, I'm a bit of a visual studio noob. I have just restarted a project in which I am using NHibernate. The project worked fine last time I used it but now is giving the following error.

What is the best way to get this up and running again? Try and find the appropriate version of the dll or sort out the manifest file? Any pointers much appreciated.

  • ArrayCollection error in Flex does not accept single XML nodes - alternatives?

    - by Rees
    hello, i get this error when i retrieve an XML that only has 1 node (no repeating nodes) and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection. this error occurs as the line of code: myList= e.result.list.name; Why can't ArrayCollection work with a single node? I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider? Thanks in advance! code: [Bindable] private var myList:ArrayCollection= new ArrayCollection(); private function getList(e:Event):void{ var getStudyLoungesService:HTTPService = new HTTPService(); getStuffService.url = "website.com/asdf.php"; getStuffService.addEventListener(ResultEvent.RESULT, onGetList); getStuffService.send(); } private function onGetList(e:ResultEvent):void{ myList= e.result.list.name; }

  • How can I dispatch an PropertyChanged event from a subscription to an Interval based IObservable

    - by James Hay
    I'm getting an 'UnauthorizedAccesExpection - Invalid cross-thread access' exception when I try to raise a PropertyChanged event from within a subscription to an IObservable collection created through Observable.Interval(). With my limited threading knowledge I'm assuming that the interval is happening on some other thread while the event wants to happen on the UI thread??? An explanation of the problem would be very useful. The code looks a little like: var subscriber = Observable.Interval(TimeSpan.FromSeconds(1)) .Subscribe(x => { Prop = x; // setting property raises a PropertyChanged event }); Any solutions?

  • How to use map/reduce to handle more than 10000 unique keys for grouping in MongoDB?

    - by Magnus Johansson
    I am using MongoDB v1.4 and the mongodb-csharp driver and I try to group on a data store that has more than 10000 keys, so I get this error: assertion: group() can't handle more than 10000 unique keys using c# code like this: Document query = new Document().Append("group", new Document() .Append("key", new Document().Append("myfieldname", true)) .Append("$reduce", new CodeWScope( "function(obj,prev) { prev.count++; }")) .Append("initial", new Document().Append("count", 0)) .Append("ns", "myitems")); I read that I should use map/reduce, but I can't figure out how. Can somebody please shed some light on how to use map/reduce? Or is there any other way to get around this limitation? Thanks.

  • Can't set breakpoints on an auto-property setter ? Why?

    - by Cristi Diaconescu
    Apparently VS 2008 does not allow setting a breakpoint just on the setter of an auto-property. I.e. if I define an auto-property like this: public int CurrentFramesize { get; protected set; } and then try to set a breakpoint on the setter line, the whole auto-property turns breakpoint-red. This works just fine for normal properties, so any idea why auto-properties get this special (restrictive) treatment? Are they more than just syntactic sugar to normal properties with a hidden backing field?

  • Setting the a caret in an JEditor Pane causes an exception.

    - by Elliott
    I have a JeditorPane which has some text in HTML format. When I execute the following command int len = editorPane.getText().length(); The value for len is 7473. But then I try to do the following: editorPane.setCaretPosition(4995); And I get the following exception: java.lang.IllegalArgumentException: bad position: 4995 My understanding is that I should only get this exception if the position at which I'm trying to set the caret is less than 0 or greater than the text length. It is neither. How can this be. Thank you, Elliott

  • Get the UIWindow which is under the UIActionSheet

    - by Georgi
    I am trying to present a new UIViewController on top of the current current UIViewController. Here is the line of code that creates the desired effect: LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil]; UIViewController *rootController = [[[UIApplication sharedApplication] keyWindow] rootViewController]; [rootController presentViewController:loginViewController animated:YES completion:nil]; The problem is that I added an UIActionSheet which asks the user to confirm the desired action (which is to log out). When the user confirms the action I run the above mentioned peace of code, but the UIActionSheet is still the keyWindow. Therefore the LoginViewController is not presented on top (the rootController is null when I try to debug). My question is: Can I somehow find the UIWindow which is under the UIActionSheet and from there get the root controller,or maybe I can dismiss programmatically the UIActionSheet when the users selects the log out action and only then execute the above code? Thank you in advance!

  • Does Javascript/EcmaScript3 support ISO8601 date parsing?

    - by AlexanderN
    How are you currently parsing ISO8601 dates e.g. 2010-02-23T23:04:48Z in JavaScript? Some browsers return NaN (including Chrome) when using the code below, FF3.6+ works though. <html> <body> <script type="text/javascript"> var d = Date.parse("2010-02-23T23:04:48Z"); document.write(d); </script> </body> </html> You can try this here http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_parse ps: DateJs doesn't seem to support ISO8601 parsing.

  • Problem using Blend 3 Interaction.Behaviours in VS2010

    - by Andre Luus
    There seems to be a problem with support for the Interactivity namespace of Blend 3 in the VS2010 xaml editor. I have the following installed: VS2010 Blend 3 + Blend 3 SDK I am trying to compile a demo project that is targeted at .Net 4 Client Profile and has a reference to System.Windows.Interactivity (in the Blend 3 folder). In the object browser everything appears to be fine. I can also access Interaction.Behaviours from code-behind, but if I put the namespace xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" in the xaml file and try to use it, the intellisense is blank. If I copy something in there anyway, the compiler says: The tag 'Interaction.Behaviors' does not exist in XML namespace 'http://schemas.microsoft.com/expression/2010/interactivity'. Do I need to install Blend 4 RC or something?

  • Using Add-on SDK to add toolbar buttons? Integrating XUL and Add-on SDK for Firefox Add-ons?

    - by Salami
    I have already coded most of a Firefox add-on using the Add-on SDK API. I am now discovering that Add-on SDK might not be powerful enough for my purposes. I need two things: A drop down button in the toolbar next to the location bar. To modify the add-ons manager in firefox It is truly disappointing, but I don't believe either of these is possible with the Add-on SDK. First of all, I understand there is a widget module in the Add-on SDK API. But this only allows me to add a simple icon or label to the awkward add-on bar. What if I need to add a nicer button like the one next to the location bar for Firebug or Greasemonkey? As for modifying the add-ons manager in firefox, I have tried Nickolay Ponomarev's XUL with the Add-on SDK without any success whatsoever. If anyone knows how to get this working and can point me in the right direction that would be extremely helpful (cfx init --template xul doesn't do anything the regular SDK does when I try it)

  • Reading a document's content from the gdata API?

    - by user246114
    Hi, I'm using the java library to access the gdata api. I just want to be able to print the contents of a document. I setup my project to list all the docs in my feed, now that I have a document listing, I want to print its contents: for (DocumentListEntry entry : feed.getEntries()) { // Ok, how do we print the doc's contents now? entry.getContents(); } It looks like we're supposed to get the URL from the entry, then read the contents at the URL ourselves. I found a post stating that this is how we get that URL: MediaContent content = (MediaContent)entry.getContent(); String url = content.getUri(); but when I try to read from it, I get an html response saying 'this content has moved'. I read that this is because we have to authenticate our http-read method, but I'm not sure how to do that. Is there really no built-in way to do this? Thanks

  • CoffeeScript on Windows?

    - by Nick Perkins
    How can I try CoffeeScript on Windows? The installation instructions are only for *nix: http://jashkenas.github.com/coffee-script/#installation EDIT: I don't think I need node.js -- I am just writing javascript for web pages, (using some jQuery, etc)...So all I really want is simple way to write CoffeeScript and "compile" it down to JavaScript. Isn't there a Ruby program that would do it? Or even better, a windows exe? (i dont use ASP.NET either...i use Python/Django) FINAL EDIT: Thanks for the help -- In the end I installed VirtualBox and created a virtual Linux machine which I now use to program coffeescript with node.js. (It was surprisingly easy to start using VirtualBox -- easier than doing the Cygwin thing). I run jEdit (for which you can get a CoffeeScript syntax highlighter) and I put the corresponding js file side-by-side with the coffeescript file. When I compile the coffeescript to js, the editor automatically re-loads the new javascript, which allows me to check that it has compiled the way I expect (which is a good thing while learning the coffeescript syntax).

  • Problem reading hexadecimal buffer from C socket

    - by Olaseni
    I'm using the SDL_net sockets API to create a server and client. I can easily read a string buffer, but when I try to send hexadecimal data, recv gets the length, but I cannot seem to be a able to read the buffer contents. IPaddress ip; TCPsocket server,client; int bufSize = 1024; char message[bufSize]; int len; server = SDLNet_TCP_Open(&ip); client = SDLNet_TCP_Accept(server); len = SDLNet_TCP_Recv(client,message,bufSize); Here's a snippet. the buffer length "len" is set (i.e. message length) but I can't get to the data contents in the message buffer. Some sample bind_transmitter PDU data was sent by a random client to the server at that port. I can't read the PDU (SMPP).

  • How to create multiple SOAP webservice clients in same netbeans 6.8 project

    - by James Black
    I have a project that is largely just to help one application make connections to an SAP server, for real-time updates. So the first web service client works fine, but I try to create a second and it seems to hang and I expect part of the problem is that it is trying to create a new Service class, but the namespace for all the webservices are identical, but the wsdl is obviously different, so it can't create the client. I can do it manually, by just having Service1, Service2, etc, or making some other change, but the issue is that Netbeans should be able to do this easily. I can't use Eclipse as the wsimport parameters that Netbeans uses works, in Eclipse I would need to do too much to make it work, so I will go with the easier tool. I don't want to create a new project for each webservice, as that just seems to be perpetuating a design error. So, how can I easily create multiple webservice clients that will all have the same target namespace, using Netbeans 6.8+?
