  • Ruby w/ Postgres & Sinatra - Query won't order right with parameter??

    - by alleywayjack
    So I set a variable in my main ruby file that's handling all my post and get requests and then use ERB templates to actually show the pages. I pass the database handler itself into the erb templates, and then run a query in the template to get all (for this example) grants. In my main ruby file: grants_main_order = "id_num" get '/grants' do erb :grants, :locals => {:db=>db, :order=>grants_main_order, :message=>params[:message]} end In the erb template: db = locals[:db] getGrants = db.exec("SELECT * FROM grants ORDER BY $1", [locals[:order]]) This produces some very random ordering, however if I replace the $1 with id_num, it works as it should. Is this a typing issue? How can I fix this? Using string replacement with #{locals[:order]} also gives funky results.

  • Clean way in GWT/Java to wait for multiple asynchronous events to finish

    - by gerdemb
    What is the best way to wait for multiple asynchronous callback functions to finish in Java before continuing. Specifically I'm using GWT with AsyncCallback, but I think this is a generic problem. Here's what I have now, but surely there is cleaner way... AjaxLoader.loadApi("books", "0", new Runnable(){ public void run() { bookAPIAvailable = true; ready(); }}, null); AjaxLoader.loadApi("search", "1", new Runnable(){ public void run() { searchAPIAvailable = true; ready(); }}, null); loginService.login(GWT.getHostPageBaseURL(), new AsyncCallback<LoginInfo>() { public void onSuccess(LoginInfo result) { appLoaded = true; ready(); } }); private void ready() { if(bookAPIAvailable && searchAPIAvailable && appLoaded) { // Everything loaded } }

  • Setting selected item on Listbox in Silverlight - Windows Phone 7

    - by Fishcake
    I have a databound Listbox bound to a generic list as follows (Provider is a very simple class that just includes a single property (Name). ProviderList = new List<Provider>(); //Populate list Providers.ItemsSource = ProviderList; I can save the selected item with no problem but I can't manage to set the selected item from code afterwards. I am trying to do so as follows: int x = Providers.Items.IndexOf((Provider)_Settings["provider"]); However IndexOf() is always returning -1. If I inspect both Providers.Items[1] and _Setting["provider"] at runtime using the immediate window they both return {StoreRetrieveData.Provider} Name: "Greenflag" Am I doing something wrong (well clearly I am)?

  • Which is the UI technology of the future considering: eye-candy-effect, interactivity (gestures, voc

    - by user193655
    If you had to write a next-gen application, in which on the surface (UI) you need some "futuristic features", by considering the following aspects which is the choice you'd make? 1) eye-candy: cool UI, 3D, Effects, nice graphics, sound transitions... 2) user interaction: not only mouse and keyboard but touch, voice and more.... + user interactivity aspect, which is the technology you'd choose? 3) X-platform: this is to have some X-platform discussion. Of course single platform technologies (as WPF) have may be some more power, anyway in a general discussion considering X-platform as a resource is important 4) available components: of course the coolest technology with no available components is may be an option for a component developer but not for an application developer My question is generic, but anyway * have in mind data-driven apps, not pure multimedia apps, videogames, ....

  • Using threads and event handlers within a WCF Web Service

    - by user368984
    While making a WCF Web Service, I came across a problem while using a method with a webbrowser control. The method starts a thread and uses a webbrowser control to fill in some forms and click further, waiting for a event handler to fire and return a answer I need. The method is tested and works within its own enviroment, but used in a WCF Web Service enviroment, the event handlers just won't fire. A result of that is the waiting manualresetevent not ending. Is this because of the new thread or because of the bad event handling of the web service? If yes, what is a reasonable solution?

  • Can Uploadify send e-mail on complete?

    - by David
    Uploadify is a jQuery/Flash plugin for uploading multiple files. It's working great, except I can't figure out how trigger e-mail when all files are complete. If I try to add something like <% SendEmail(); %> to the onAllComplete parameter, it just sends the e-mail when the page loads. Is there a way to do this within the handler recommended here or from this post? Or is there some way to trigger a post in the onAllComplete parameter?

  • Editing a TreeView node doesn't change the TreeNode Key

    - by Blitzz
    I have a TreeView with user-editable nodes. I like to use the node caption as key to my tree node : + Root |+ Node1 ||- SubNode1 ||- SubNode2 |+ Node2 ||- SubNode3 ||- SubNode4 So I can reach a node like this: MyTreeView.Nodes["Root"].Nodes["Node2"].Nodes["SubNode3"] The problem is that, as I allow the user to rename any node, I would need also to change the key of my node in its parent in the AfterLabelEdit handler... which seems (logically) not to be done automatically. Unfortunately, Nodes["blabla"] is readonly, Nodes.Add(string Key, TreeNode Node) doesn't exist, and I can't find a way to do this without throwing (sooner or later) a bad exception. Any idea ?

  • Searching pgadmin db and grabbing information?

    - by Bootstrotter
    I'm currently trying to write a script in RoR to go into my PGAdmin database and look at a list of users, THEN ignore users that have an image path but look at users who don't have one and then upload a link of a generic photo into their row. My database looks Something like this: id integer | name | email | image path | 12 Bob [email protected] www.faces.org 81 Sally [email protected] 114 Mark [email protected] www.faces.org How would I start grabbing those users, I only have 103 users right now, but I also need to think about scaling for the future. Here is a starting point. I know this is kind of vague but really all I need is just a starting point. to get into it. Thanks for the information. require 'sqlite3' db = SQlite3 users = users.find([1, 103]) Any help would be great.

  • In .NET, what thread will Events be handled in?

    - by Ben
    I have attempted to implement a producer/consumer pattern in c#. I have a consumer thread that monitors a shared queue, and a producer thread that places items onto the shared queue. The producer thread is subscribed to receive data...that is, it has an event handler, and just sits around and waits for an OnData event to fire (the data is being sent from a 3rd party api). When it gets the data, it sticks it on the queue so the consumer can handle it. When the OnData event does fire in the producer, I had expected it to be handled by my producer thread. But that doesn't seem to be what is happening. The OnData event seems as if it's being handled on a new thread instead! Is this how .net always works...events are handled on their own thread? Can I control what thread will handle events when they're raised? What if hundreds of events are raised near-simultaneously...would each have its own thread?

  • Collectable<T> serialization, Root Namespaces on T in .xml files.

    - by Stacey
    I have a Repository Class with the following method... public T Single<T>(Predicate<T> expression) { using (var list = (Models.Collectable<T>)System.Xml.Serializer.Deserialize(typeof(Models.Collectable<T>), FileName)) { return list.Find(expression); } } Where Collectable is defined.. [Serializable] public class Collectable<T> : List<T>, IDisposable { public Collectable() { } public void Dispose() { } } And an Item that uses it is defined.. [Serializable] [System.Xml.Serialization.XmlRoot("Titles")] public partial class Titles : Collectable<Title> { } The problem is when I call the method, it expects "Collectable" to be the XmlRoot, but the XmlRoot is "Titles" (all of object Title). I have several classes that are collected in .xml files like this, but it seems pointless to rewrite the basic methods for loading each up when the generic accessors do it - but how can I enforce the proper root name for each file without hard coding methods for each one? The [System.Xml.Serialization.XmlRoot] seems to be ignored.

  • Don't Change URL in Browser When Clicking <asp:LinkButton>

    - by Corey Goldberg
    I have an ASP.NET page that uses a menu based on asp:LinkButton control in a Master page. When a user selects a menu item, an onclick handler calls a method in my C# code. The method it calls just does a Server.Transfer() to a new page. From what I have read, this is not supposed to change the URL displayed in the browser. The problem is it that the URL changes in the browser as the user navigates the menu to different pages. Here is an item in the menu: <asp:LinkButton id="foo" runat="server" onclick="changeToHelp"><span>Help</span> </asp:LinkButton> In my C# code, I handle the event with a method like: protected void changeToHelp(object sender, EventArgs e) { Server.Transfer("Help.aspx"); } Any ideas how I can navigate through the menu without the browser's URL bar changing?

  • Enumerable.Range in and Expression and Entity Framework

    - by eka808
    I'm currently developping an expression method (used in linq to entity queries) who has to give me a daycount for a given period (start date and end date) decrementing this daycount if specials days are in the period. My idea was the following : Generate an enumerable with all the dates (and with Enumerable.Range) Make a .Where on this enumerable to remove the specials dates Like a MyEnumerable.Where(a = a != "20120101") After that, return a MyEnumerable.Count() I come with this code : return (p) => Enumerable .Range(1, 4) .Where(a => a != 20120101) .AsQueryable() .Count() I tried to cast as a list, as a queryable, both (like the example) and no way ! it doesn't work ! I always get this error : LINQ to Entities does not recognize the method 'System.Collections.Generic.IEnumerable`1[System.Int32] Range(Int32, Int32)' method, and this method cannot be translated into a store expression. Have you got an idea about that ? Using an enumerable is of course not mandatory, any working solutions is good ^^ Thank's by advance !

  • Are protected constructors considered good practice?

    - by Álvaro G. Vicario
    I'm writing some little helper classes to handle trees. Basically, I have a node and a special root node that represents the tree. I want to keep it generic and simple. This is part of the code: <?php class Tree extends TreeNode{ public function addById($node_id, $parent_id, $generic_content){ if( $parent = $this->findNodeById($parent_id) ){ $parent->addChildById($node_id, $generic_content); } } } class TreeNode{ public function __construct($node_id, $parent_id, $generic_content){ // ... } protected function addChildById($node_id, $generic_content){ $this->children[] = new TreeNode($this->node_id, $node_id, $generic_content); } } $Categories = new Tree; $Categories->addById(1, NULL, $foo); $Categories->addById(2, NULL, $bar); $Categories->addById(3, 1, $gee); ?> My questions: Is it sensible to force TreeNode instances to be created through TreeNode::addById()? If it's so, would it be good practise to declare TreeNode::__construct() as private/protected?

  • Why do my WPF UIElements NOT have OnPreview events?

    - by Matt.M
    I'm building a custom Silverlight UserControl which needs to listen to events using Preview/Tunneling, but for some reason the compiler is telling me they are not recognized or accessible. For example, I can add an event handler to MouseLeftButtonDown, but not PreviewMouseLeftButtonDown. This doesn't make sense because according to Microsoft (http://msdn.microsoft.com/en-us/library/system.windows.uielement_members(v=VS.100).aspx) all UIElements should have Preview events attached. Any ideas as to why this is happening? I'm using Visual Studio 2010 Trial, Blend 4 RC and .Net 4, if that makes a difference.

  • .NET 2.0: Invoking Methods Using Reflection And Generics Causes Exception

    - by David Derringer
    Hi all, I'm new to Stack Overflow, so forgive me. I've just started transititoning over to C# and I am stuck on a problem. I am wanting to pass a generic class in and call a method from that class. So, my code looks as such: public void UpdateRecords<T>(T sender) where T : new() //where T: new() came from Resharper { Type foo = Type.GetType(sender.GetType().ToString()); object[] userParameters = new object[2]; userParameters[0] = x; userParameters[1] = y; sender = new T(); //This was to see if I could solve my exception problem MethodInfo populateRecord = foo.GetMethod("MethodInOtherClass"); populateMethod.Invoke(sender, userParameters); } Exception thrown: "Object reference not set to an instance of an object." Again, I really apologize, as I am nearly brand new to C# and this is the first time I've ever handled reflection and generics. Thank you!

  • Why specifcially in my example does this "too much recursion" error occur in my JavaScript?

    - by alex
    I have been looking into this for a little while now. I have a gallery on my page, that uses Ariel Flesler's scrollTo plugin. It works fine on the home page, but not on the Contact page. In Firefox, I get the error... Too much recursion I have sorted through as much code as possible and set breakpoints in a few places. I am pretty sure it is something to do with the plugin (specifically, when it is called in the click handler). For your convenience, I am using the unpacked versions of jQuery and scrollTo plugin. What on earth am I doing wrong? Thanks for your time.

  • How to send exceptions to exceptionController?

If I comment out the mappedHandlers part then the error tile is displayed but it is only a tile. The rest of the tiles load normally. I need to make a redirect in the controller so I can show an error page not just an error tile. I can't find enough information or an example how the exception invokes some method in exceptionController.

  • Threading errors with Application.LoadComponent (key already exists)

    MSDN says that public static members of System.Windows.Application are thread safe.

  • Qt: Dragging a widget to scroll the widget's parent QScrollArea?

    - by samsonite
    I've got a long horizontal QLabel displaying a png (the image shows a signal/time graph). Under that, I've got a QTableWidget. Both of these are in a QScrollArea because I want them to stay vertically aligned (the cells in the table correspond with the signal seen directly above them). I'm trying to add a handler to the QLabel such that the user can use the picture itself to scroll the scrollarea, rather than having to use the scrollbar. Is there a tried-and-tested way to do this? Directly setting the scrollarea's sliderPosition inside the QLabel's dragMoveEvent doesn't seem smart, because when the scrollarea scrolls it also leads to another dragMoveEvent on the (moving) QLabel.

  • R: how to make a unique set of names from a vector of strings?

    - by Mike Dewar
    Hi, I have a vector of strings. Check out my vector, it's awesome: > awesome [1] "a" "b" "c" "d" "d" "e" "f" "f" I'd like to make a new vector that is the same length as awesome but where, if necessary, the strings have been uniqueified. For example, a valid output of my desired function would be > awesome.uniqueified [1] "a" "b" "c" "d.1" "d.2" "e" "f.1" "f.2" Is there an easy, R-thonic and beautiful way to do this? I should say my list in real life (it's not called awesome) contains 25000ish mircoarray probeset identifiers. I'm always nervous when I embark on writing little generic functions (which I'm sure I could do) as I'm sure some R guru has come across this problem in the past, nailed it with some incredible algorithm that doesn't even have to store more than half an element in the vector. I'm just not sure what they might have called it. Probably not uniqueify.

  • Delphi: How to call a method when i click a control?

    - by Ian Boyd
    i have a method: procedure Frob(Sender: TObject); that i want to call when i click a menu item. The method comes to me though an interface: animal: IAnimal; IAnimal = interface procedure Frob(Sender: TObject); end; The question revolves around what to assign to the OnClick event handler of a menu item (i.e. control): var animal: IAnimal; ... begin ... menuItem := TMenuItem.Create(FileMenu) menuItem.Caption := 'Click me!'; menuItem.OnClick := <-------- what to do ... end; The obvious choice, my first attempt, and the wrong answer is: menuItem.OnClick := animal.Frob; So how can i call a method when user clicks a control?

  • Is there a better acts_as_commentable for Rails?

    - by levi rosol
    Here's what I'm looking to do. I have a site where I want the user to be able to leave comments on various Models. acts_as_commentable is the obvious starting point for this, but I'm curious if there is a gem / plug-in with a more robust feature-set. For example: Pre-built partial(s) (w/ or w/o Twitter / FB buttons) Partial(s) that utilize jQuery Twitter and / or FB tunnels (push to the users twitter / FB when they comment) Pre-built mechanism for pushing other users comments to users viewing that Model I can see how some of this functionality could be app specific, however, a generic implementation seems like it would be useful. I'm curious if something like this exists or not.
