  • Silverlight MVVM example which does not use data grids?

    - by Aim Kai
    I was wondering if anyone knew of a great example of using the MVVC pattern for a Silverlight application that does not utilise a data grid? Most of the examples I have read see links below and books such as Pro WPF and Silverlight MVVM by Gary Hall use a silverlight application with a datagrid. Don't get me wrong, these are all great examples. See also: MVVM: Tutorial from start to finish? http://www.silverlight.net/learn/tutorials/silverlight-4/using-the-mvvm-pattern-in-silverlight-applications/ However some recent demo projects I have been working are not necessarily dealing with data grids but I would still want to implement this pattern..

  • jQuery - iGoogle style interface

    - by samhamilton
    Hi all, I'm currently working on developing a customizable website layout using jQuery, so I can drag, drop, add and remove blocks of content... much like the iGoogle interface. I have my blocks dragging and dropping working with 3 columns of content My question is to do with adding and removing blocks If I use hide(), I can simply hide and show the blocks. If I use remove, I would have to append the list of blocks to load in a new block into a column. I'm not sure which is the best approach to take. I'd be grateful for any advice on best practise, i.e. to hide() or remove() and any other advice on building this kind of interface. Thank, Sam.

  • CSS float column extending over footer

    - by JD
    Hi, I am having a problem with my CSS whereby the right hand column in a 2 column layout is extending beyond the footer. I have tried playing with the clear: both; property but I cannot get it to work.. the second column has the id column2 both columns use the class column. The footer html has the id footerWrapper Both columns and footer are div tags. My CSS (abridged): .column { width: 49%; } #column2 { width: 50%; position: absolute; top: 0px; margin-left: 50%; float: left; } #footerWrapper { background-color: #333333; border-top: 2px #FF6600 solid; color: #666; }

  • How to use custom color for each textview in listview that extends SimpleAdapter in Android ?

    - by mob-king
    I have a listview with custom rows and that extends SimpleAdapter. Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation. Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row. To put it as simple: each listview item has some custom colors the value of which comes from the hidden field. I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it). Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other ? Any help ? Thanks.

  • facebook iphone app architecture

    - by xoail
    does anyone know or predict how facebook's iphone app architecture could look like? More specific to what could be built into the app (client) what could be rendered on demand? Do you think the main menu layout of the app (where all the navigation buttons are there) are on the client or being rendered dynamically? Similarly apps like NYTimes or US News, what portion is done on the client and what is rendered dynamically. What could be the best way to render things on-demand. Would it be ok to use to UIWebView and render most of the app in it? A quick overview would help. Thank you!

  • haml / rails: yield title with german umlauts

    - by Maxem
    Hi, I would like to do something like this in my application layout: %title= "#{yield(:sub_title)} - Page Name" and in a real view - content_for :sub_title do Übersicht # I tried &Uuml;bersicht, != "&Uuml;bersicht" and a bunch of other methods what happens is, I either get the black pound with the question mark in it - wrong encoding or the raw string (&UumI;bersicht). Does anyone know a way how to get this to work? Another requirement is that I'd like to show user generated content in the title and this content may or may not have umlauts in it. Used versions: Haml 3.0.11, Rails 3 beta4 and currently for development JRuby 1.5

  • Cocoa Key event problem

    - by Oscar
    I'm trying to build my first cocoa application. done some iPhone developing before. I have a hard time understanding how to layout my project. i making a Pong game and my current design is to allocate an NSWindowController from my appDelegate. I then use custom view to act as paddles and ball. My problem is that i can't get the window controller to capture key events. Am i thinking wrong here? My idea is to have a controller class with all the logic, should i subclass another class for that?

  • How to plan my web based project before starting code ?

    - by Arsheep
    Me and my friend started working together as partners , we have decided to make Kick-as* website after website. We have the ideas written down like 100's of them (yes we are choosing best and easy among them first). My friend does the layout design and arranging things , and my part is coding and server management. The little problem i am facing is lack of experience in planing a project. What i do is, I just start the code straight away and along with code I make DB, like when i need a table i make it. I know this is very bad approach for a medium sized project. Here at stackoverflow i saw lots of experienced coders. Need to learn a lot from you guys :) . So can you plese help me on how to plan a project and what coding standard/structure/frameworks to be used (I do PHP code). Thanks in advance.

  • CMS common Architecture

    - by Shalan
    Hi there, I know this is a weird question to ask, but I would like to know if there is any documentation/blog-article out there that explains the architecture of a Website content management system? More particularly, I am interested to learn more about how "widgets" are implemented. I can't remember which system it was that I've seen tis one, but in the "Page Layout view" it had the ability to allow the end user to select a widget (thumbnail gallery, contact form, etc) from a list, and drag and drop it onto custom areas of the page. I know that this is not directly a programming question, but please could I seek advice/feedback on this. Thanks!

  • ADT will not allow creation of Android Activity

    - by NewShelbyWoo
    I installed the ADT bundle from http://developer.android.com/sdk/index.html yesterday, and I was following a basic Hello World tutorial. I created a new Android Application Project with a Blank Activity named MainActivity. The resulting project has an empty src folder and empty res\layout folder. There is a R.java file in the gen folder but it has no reference to MainActivity. This is what the SDK manager says I have installed Android SDK Tools v 22.6 Android SDK Platform-tools v 19.0.1 Android SDK Build-tools v 19 SDK Platform v 3 ARM EABI v7a System Image v 2 Android Support Library v 19.0.1 Google USB Driver v 9 I also tried manually creating an activity by right clicking the src folder and going to Android Activity, but when I hit Finish on the creation wizard, nothing happens. Does anyone have any clues as to what's going on? Did I miss a key component to install or something?

  • Best way to deal with multiple layouts in symfony

    - by Pierre
    Hey folks. I'm looking for the best way to do something simple in symfony. Basically, I have a module in which all the pages will contain the same header and footer. That module also shares the same general layout as the other modules. I'm just wondering, should I create one file and have my content pages called up as partials or should all files have their own content and somehow call the two other templates. I made a quick example of my setup: http://grab.by/3Riy Hopefully, it'll help understand what I'm trying to do. Thanks!

  • Rotation of ViewController in TabbarController

    - by hanno
    I have a custom UIViewController in a UITabbarController and want to respond to rotation events. When a rotation occurs, the tabbarcontroller and the viewcontroller get rotated. However, the view in the viewcontroller doesn't get redrawn properly: the layout doesn't autoresize and it is black on parts of the screen. The strange thing is that it works when I go to another tab and the back again to my original viewcontroller. What could possibly be wrong? I checked that didRotateFromInterfaceOrientation:fromInterfaceOrientation is being called. However, the view.frame.size values are still the old ones from before the rotation. That's probably not correct.

  • What option in Visual Studio let catching exception where it occurred?

    - by macias
    VS 2010. The same WPF project, debug mode, two computers: A -- when exception occurrs the caret is placed at the point of exception B -- when the exception occurrs, correct exception is placed but always caret is placed at "win.ShowDialog()" in App.xaml.cs -- this is main entry for showing & running my application, in such case it is very tiresome to track down where the exception occurred What kind of settings control such behaviour? Of course I would like to switch B, so when exception hits I would be place at the point of exception, not at the main entry.

  • SSIS - Can I get the column schema for a flat file source from a database?

    - by Steve Clement
    We receive a nightly data export from a vendor in the form of about 10 tab-delimited flat file without column headers. In addition, the vendor provides us with the SQL scripts for the database tables so that we can import the files into our system. Unfortunately, the vendor recently changed the schema for the flat files. Each file has upwards 150 columns, and having to go through the DB schema and adjust column types on a Flat File Data Source in SSIS is extremely time consuming, not to mention a royal pain. Since I know the file data layout in the database schema, is there any way I can dynamically pull that into a Flat File source to set the columns correctly? Or am I just stuck with manually setting everything?

  • iPhone: Setup static content of UITableView

    - by Martin
    This guide from apple https://developer.apple.com/iphone/prerelease/library/documentation/UserExperience/Conceptual/TableView_iPhone/TableViewCells/TableViewCells.html (you need login) explains how to use "The Technique for Static Row Content" to use Interface Builder to setup the cells in a tableview. I have some cells with different heights in my tableview. Without using the heightForRowAtIndexPath method everything get messed up. Do I still need to use this method or can I in some way setup the height of the cells inside the IB as I created them there? Also when using the "The Technique for Static Row Content" from the guide you still need to use the cellForRowAtIndexPath to setup the cells even if they are created in IB. I would like to setup the full layout of the tableview with all cells in IB (drag the cells right into the tableview), is that possible in some way? Thanks!

  • Avoid hourglass mouse cursor when calling a web-service?

    - by BigMoose
    I don't know if this is a general web-services issue or just my specific scenario, which is a WPF application with a DispatcherTimer calling a web-service method. Whenever the timer is called, the mouse cursor automatically changes to an hourglass cursor. The processing of the call is very short and happens every 3 seconds, so the user experience is that every 3 seconds the mouse filckers as an hourglass for a split-second and then goes back to the normal cursor representation. How can I avoid this inconvenience? Thanks.

  • Android Multiple objects in SimpleAdapter

    - by Adam Sherratt
    I have a need (unless you can think of a better way) of passing multiple objects to a custom list adapter. I know that I'm barking up the wrong tree here, and would appreciate someone setting me on the right course! Thanks playlistadapter = new MyPlaylistAdapter(MyApplication.getAppContext(), songsList, retained_songsList, folderMode, R.layout.file_view, new String[] { "songTitle","songAlbum", "songPath" }, new int[] { R.id.checkTextView, R.id.text2, R.id.text3 }); And my adapter class: public class MyPlaylistAdapter extends SimpleAdapter{ private ArrayList <Song> songsList = new ArrayList<Song>(); private ArrayList <Song> retained_songsList = new ArrayList<Song>(); private ArrayList<Song> playlistcheck = new ArrayList<Song>(); private String folderMode; private String TAG = "AndroidMediaCenter"; public MyPlaylistAdapter(Context context,List<Song> SongsList, List<Song> Retained_songsList, String FolderMode,int resource, String[] from, int[] to) { super(context, null, resource, from, to); songsList.clear(); songsList.addAll(SongsList); Log.i(TAG, "MyPlayListAdapter Songslist = " + songsList.size()); retained_songsList.clear(); retained_songsList.addAll(Retained_songsList); folderMode = FolderMode;

  • How to check code is compatible with Windows 7

    - by Julen
    Hello, We are developing using Visual C# 2008 Express a program based on WPF under Windows XP machines (32 bits). The thing is that we have tried to run the program in two Windows 7 machines, one is 32 bits Windows 7 and the other is 64 bits Windows 7. Under Windows XP everything is fine. In Windows 7 machine, it launches in the 32 bits version altough there is an error when running one functionality (it does not happen in XP). In W7 64 bits it even does not launch. Is this normal? Is not possible to run 32 bit programs under W7 64-bits,even if they execute slower?? How can we check the code is compatible with Windows 7? Thank you very much in advance. Julen.

  • How do I visualize a complex graph in .Net?

    - by Ivan
    I need to visualize a graph (technically being a set of Entity Framework objects, but I can translate it to another representation if needed) of this kind. I don't know how to name it (by the way, if you know - I'll appreciate if you tell me). It would be ideal for graph elements to be clickable (so that when user clicks on a block, I can handle an event with the element id specified) but I can survive even without any interactivity. Are there any components available good for this task? If no, what should I look for to help me to develop an algorithm for drawing such a graph with visually-comfortable layout?

  • How can I explain to a programmer that CSS positioning has many benefits over table based layouts?

    - by Pat
    I have a friend who wishes to work as a freelance web developer, but insists that tables are the way forwards for layouts. Several points he maintains in favour of tables: 1 This is what was taught at the beginning of 10 years of programming & computer science degrees. 2 Large companies use tables to achieve 'technical' things. 3 It saves time I have coded him some examples of CSS exactly matching table based layouts, and provided many links to articles explaining SEO and accessibility benefits. From the perspective of a client, I have been explaining to him that I wouldn't hire someone using outdated methods as their main strategy for layout. As he is my friend and I wish him every success, I believe it is important for him to gain the best start when pitching for work. The question again: How can I explain to a programmer that CSS positioning has many benefits over table based layouts?

  • Video Streaming

    - by Josephe
    First I need to state that I am not the developer so I will state the issue in business terms but please respond with a technical solution as I will be passing on your posts to the developer. We are building a web based application in SilverLight and WPF that consists of communication between a customer service rep and a customer. The application will inlcude a webcam that will provide the customer with the ability to see the customer service rep and the rep will also be able to see an image of themselves but will not be able to see the customer. Similar functionality to a live web chat with video component. There could potentially be bandwidth issues and we do not want the customer to have to download anything. Any recommendations on how to do this?
