  • Is is possible to have grouped GridView without using CollectionViewSource?

    - by Sergey Aldoukhov
    It is just seems to be a little awkward design to tie a feature to a class instead of interface. Has anybody managed to group GridView without CollectionViewSource? Also a bonus question here: why you have to refer to the CollectionViewSource resource through binding: <GridView ItemsSource="{Binding Source={StaticResource groupedData}}" > instead of <GridView ItemsSource="{StaticResource groupedData}" > ??

  • InputManager ignores cut/copy/paste when initiated from menu

    - by Wallstreet Programmer
    I'm using the InputManager to check if changes to controls are done by user or code. This works fine, except when user uses the context menu for cut/copy/paste. If the user do ctrl+v in a textbox, InputManager correctly notices it. However, if the paste is done from the context menu of the textbox, the InputManager never fires the PreNotifyInput or PostNotifyInput events. Anyone knows why? Or how to detect that these user actions? Below is a working sample. The lower textblock never gets updated when user uses the cut/copy/paste menu in the above textbox since PreNotifyInput never fires. XAML: <Window x:Class="InputMgrDemo.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <StackPanel> <TextBox TextChanged="TextBox_TextChanged" /> <TextBlock Name="_text" /> </StackPanel> </Window> Code behind: using System.Windows; using System.Windows.Controls; using System.Windows.Input; namespace InputMgrDemo { public partial class Window1 : Window { public Window1() { InitializeComponent(); InputManager.Current.PreNotifyInput += ((sender, e) => _userInput = true); InputManager.Current.PostNotifyInput += ((sender, args) => _userInput = false); } private void TextBox_TextChanged(object sender, TextChangedEventArgs e) { if (_userInput) { _text.Text = (sender as TextBox).Text; } } private bool _userInput; } }

  • Determine number of screens and screen relative location without WinForms

    - by Philipp Schmid
    I want to save and restore the window position of my WPF application. I want to make the code robust to use with multiple monitors who's number and relative location can change (I want to avoid opening my application off-screen when the monitor configuration has changed inbetween invocations). I know of the Screen class in System.Windows.Forms, but I don't want to take a dependency on that assembly just for this feature.

  • How to configure bugzilla to not advance to next bug when updating?

    - by WilliamKF
    By default, when you apply changes to a Bugzilla entry, the web interface advances to the next bug in your list. I would like to disable this feature since it is almost never what I desire, planning to make further updates later. Further, I often update the wrong bug subsequently due to its changing the current bug without my noticing. How do I configure Bugzilla to not advance like this?

  • checking mongo database for data

    - by user1647484
    I'm playing around with this tutorial that uses Sinatra, backbone.js, and mongodb for the database. It's my first time using mongo. As far as I understand it the app uses both local storage and a database. it has these routes for the database. For example, it has these routes get '/api/:thing' do DB.collection(params[:thing]).find.to_a.map{|t| from_bson_id(t)}.to_json end get '/api/:thing/:id' do from_bson_id(DB.collection(params[:thing]).find_one(to_bson_id(params[:id]))).to_json end post '/api/:thing' do oid = DB.collection(params[:thing]).insert(JSON.parse(request.body.read.to_s)) "{\"_id\": \"#{oid.to_s}\"}" end After turning the server off and then on, I could see in the server getting data from the database routes 127.0.0.1 - - [17/Sep/2012 08:21:58] "GET /api/todos HTTP/1.1" 200 430 0.0033 My question is, how can I check from within the mongo shell whether the data's in the database? I started the mongo shell ./bin/mongo I selected the database 'use mydb' and then looking at the docs (http://www.mongodb.org/display/DOCS/Tutorial) I tried commands such as > var cursor = db.things.find(); > while (cursor.hasNext()) printjson(cursor.next()); but they didn't return anything.

  • How to enable the video output on your iPad app?

    - by Sjakelien
    Just found out that the video output of the iPad is not a system level functionality, but that it needs to be explicitly build in into each app. Is there somebody who has any experience with this, who could point me to sample code? Secondary question would be: why wouldn't Apple make this a system feature. Is it a hardware issue, that I should be aware of when building this into my app?

  • Android hidden title bar comes back

    - by kasplurpo
    When my app starts, the title bar is hidden. However, if I leave the app and then return (minimize or phone goes to sleep), there is a blank bar inserted at the top. Is this an intentional feature? How can I prevent it? It seems that the bar goes away after I press the menu key. This is the relevant line in the manifest file: android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" Thanks

  • How does the Ableton warp algorithm work exactly?

    - by pepperdreamteam
    I'm looking for any documentation or definitive information on Ableton's warp feature. I understand that it has something to do with finding transients, aligning them with an even rhythm and shifting audio samples accordingly. I'm hoping to find ways to approximate warping with more basic audio editing tools. I understand that this is ableton's unique device, really any information about how it works would be helpful. So...does anyone have any 411?

  • VS2010 almost always zooms text on scroll

    - by Chris Barr
    You know the neat text zoom feature in VS2010 where you hold down Ctrl and then use your scroll wheel? Well, this seems to happen by default (and without ever pressing Ctrl) to nearly every file I open. Usually I open a file and have to scroll to some lower point, but instead it starts zooming the text! I have found that by tapping the Ctrl key VS then realizes that it should scroll instead of zoom, but it's still very annoying. Any ideas?

  • How to search multiple columns in MySQL?

    - by George
    I'm trying to make a search feature that will search multiple columns to find a keyword based match. This query: SELECT title FROM pages LIKE %$query%; works only for searching one column, I noticed separating column names with commas results in an error. So is it possible to search multiple columns in mysql?

  • What is the proper odbc command for calling Oracle stored procedure with parameters from .Net?

    - by Hamish Grubijan
    In the case of MSFT SQL Server 08, it is: odbcCommand = new OdbcCommand("{call " + SP_NAME + " (?,?,?,?,?,?,?) }", odbcConn); When I try to do the same thing for Oracle, I get: OdbcException: ERROR [HYC00] [Oracle][ODBC]Optional feature not implemented. Feel free to ask for clarification, and please help. I am using .Net 3.5, SQL Server 08, and Oracle 11g_home1. P.S. The Oracle stored procedure does have some 3 more parameters, but I believe I am handling this in my code.

  • Use PermGen space or roll-my-own intern method?

    - by Adamski
    I am writing a Codec to process messages sent over TCP using a bespoke wire protocol. During the decode process I create a number of Strings, BigDecimals and dates. The client-server access patterns mean that it is common for the client to issue a request and then decode thousands of response messages, which results in a large number of duplicate Strings, BigDecimals, etc. Therefore I have created an InternPool<T> class allowing me to intern each class of object. Internally, the pool uses a WeakHashMap<T, WeakReferemce<T>>. For example: InternPool<BigDecimal> pool = new InternPool<BigDecimal>(); ... // Read BigDecimal from in buffer and then intern. BigDecimal quantity = pool.intern(readBigDecimal(in)); My question: I am using InternPool for BigDecimal but should I consider also using it for String instead of String's intern() method, which I believe uses PermGen space? What is the advantage of using PermGen space?

  • Getting started with mvim, how to manage a project?

    - by zengr
    Hi, I have started out with macvim and now fairly comfortable with the navigation (on a single file) and now I need to write a whole project (say rails) using mvim. In textmate, you have mate project_dir which opens the project in a side drawer, so my question is: Is there a similar feature in mvim? How can a complete project managed in traditionally in macvim? Links to some write-ups are welcomed.
