• TypeScript for Visual Studio 2012

  - by TATWORTH

  Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2013/06/21/typescript-for-visual-studio-2012.aspxAt http://www.microsoft.com/en-us/download/details.aspx?id=34790, Microsoft provide a free download of TypeScript for Visual Studio 2012. The documentation site is at http://www.typescriptlang.org/It is described as TypeScript is a language for application-scale JavaScript development.TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.Any browser. Any host. Any OS. Open Source.TypeScript starts from the syntax and semantics that millions of JavaScript developers know today.TypeScript compiles to clean, simple JavaScript code which runs on any browser, in Node.js, or in any other ES3-compatible environment.With TypeScript, you can use existing JavaScript code, incorporate popular JavaScript libraries, and be called from other JavaScript code.These features are available at development time for high-confidence application development, but are compiled into simple JavaScript.If you have written JavaScript, you will know why I welcome the release of version 0.9 of TypeScript as TypeScript should be a lot less frustrating to write. I suggest you go to https://typescript.codeplex.com/ and follow this very promising project.

• Only one resolution available in Xorg.conf

  - by Kévin Guilbeault

  I recently upgraded to Ubuntu 12.10 and when I try to change my resolution in NVIDIA X server settings, I only get the native one (1600x900). When I had 12.04 installed, all resolutions were available in the drop down list. My goal is to have twinview working again. I used to set my two screens to twinview and clones, using my HDTV resolution (1360x768) which was previously available in 12.04 for my laptop screen too. In 12.10, I tried to install all of the NVIDIA drivers available except the nouveau driver. I tried to add a new mode using Xrandr --newmode / --addmode, but it didn't work; it coudn't detect my output. I'd like to know if this is a known bug and if there's something to do with that. Thanks!

• XNA: Retrieve texture file name during runtime

  - by townsean

  I'm trying to retrieve the names of the texture files (or their locations) on a mesh. I realize that the texture file name information is not preserved when the model is loaded. I've been doing tons of searching and some experimenting but I've been met with no luck. I've gathered that I need to extended the content pipeline and store the file location in somewhere like ModelMeshPart.Tag. My problem is, even when I'm trying to make my own custom processor, I still can't figure out where the texture file name is. :( Any thoughts? Thanks! UPDATE: Okay, so I found something kind of promising. NodeContent.Identity.SourceFilename, only that returns the location of my .X model. When I go down the node tree he is always null. Then there's the ContentItem.Name property. It seems to have names of my mesh, but not my actual texture file names. :(

• Is it possible to develop apps with Kendo UI to submit to iOS App Store?

  - by Farshid

  The number of platforms I have to develops apps for is increasing and It brings me lots of stress to learn new technologies for each target platform. I found out that Telerik's Kendo UI is very good to build websites that look and feel native on mobile platforms (e.g. iOS and Android). My question is, is it possible to build HTML5 apps to deploy them on iTunes App Store and Google Play? Please note that I am eager to know the possibility of creating apps (complete apps bundled in standard format of Apple and Google for distribution in their respective mobile app markets) but not websites.

• VMware Player and Ubuntu 12.04 - Full Screen

  - by DotNetStudent

  I have installed VMware Player 4.0.2 under Ubuntu 12.04 (Final) and, apart from having to patch the modules, everything went smoothly. However, there's an irritating behavior when toggling full screen mode: toggling full screen (using Virtual Machine Toggle Full Screen or Ctrl + Alt + Return), minimizing the player and maximizing it again changes the resolution of the guest to some strange one and the player gets "nested" between GNOME3's taskbar as every other of Ubuntu's native windows. To switch to full screen again I have to Ctrl + Alt + Return twice. Can anyone please tell me if this is the nromal, expected behavior? Is there any way of "correcting" it? The host operating system is Ubuntu 12.04 (Final) and the guest is Windows 7 (both 64 bits).

• How can I change resolution of "my video" in Skype?

  - by koushik

  I have a logitech Quickcam Pro 9000 connected to my ubuntu desktop and it works fine with Skype. However, Skype inputs and sends my video at the native (for the webcam I think) resolution of 1600 x 1200. I can confirm that the camera supports a wide variety of resolutions starting from 160 x 120 upto 1600 x 1200 (including e.g., 320 x 240, 352 x 288) using cheese. I can select these resolutions and see the output is appropriately scaled. Also, I don't see any improvements in smoothness of motion in the captured video so I suspect the original 1600 x 1200 is scaled down in the path somewhere. Is it possible to somehow to enable this scaling capability towards Skype?

• How do I best remove an entity from my game loop when it is dead?

  - by Iain

  Ok so I have a big list of all my entities which I loop through and update. In AS3 I can store this as an Array (dynamic length, untyped), a Vector (typed) or a linked list (not native). At the moment I'm using Array but I plan to change to Vector or linked list if it is faster. Anyway, my question, when an Entity is destroyed, how should I remove it from the list? I could null its position, splice it out or just set a flag on it to say "skip over me, I'm dead." I'm pooling my entities, so an Entity that is dead is quite likely to be alive again at some point. For each type of collection what is my best strategy, and which combination of collection type and removal method will work best?

• Custom .NET apps and clustering

  - by Ahmed ilyas

  So for a clustered environment - how would this work with your apps? what about your own custom .NET apps? Would there be a special way to develop them? I know that you can say create a simple Hello world app, and cluster that but they wouldnt be something you could see interms of the UI or anything, so they would effectively need to be developed as a Windows Service perhaps or even as a standard Console app which runs and not wait for user input but you wouldnt see any output from it (unless you redirect output to somewhere else) What im getting at here is... for those who have experience or developed a cluster application in .NET, how did you do it and what are the things to be aware of? For example we have the cloud service - fundamentally its built on clustering - if there is an outage, another node takes place and service is resumed as normal but we dont really see much of that downtime.

• Multi language switch links translated or in current language?

  - by FFish

  Should I do: A: translate the language links in the current language: (if I am on the English version) <a href="en/">English</a> | <a href="it/">Italian</a> | <a href="fr/">French B: the links in the native languages: <a href="en/">English</a> | <a href="it/">Italiano</a> | <a href="fr/">Français</a> From a user perspective option B is obvious, but what about SEO?

• MSM Merge Modules in Visual Studio 2013 [on hold]

  - by theGreenCabbage

  Could someone please let me know where I might find resources for creating MSM files? While I am able to create MSI files using InstallShield, it seems that Visual Studio no longer supports Merge Module Projects, judging by the link below and the screenshot of my version of Visual Studio 2013 - http://msdn.microsoft.com/en-us/library/z6z02ts5(v=vs.80).aspx To create a new merge module project: On the File menu, point to Add, then click New Project. In the resulting Add New Project dialog box, in the Project types pane, open the Other Project Types node and select Setup and Deployment Projects. In the Templates pane, choose Merge Module Project.

• Game getting progressively laggier?

  - by Valentin Krummenacher

  I have a small game in HTML5 that uses socket.io to communicate with a node.js server. Now my problem is that, eversince I did my last update on it it seems to have something "chunk up" in the background making it laggier and laggier the longer it runs. In the update were a few temporary local variables being defined with var(you know, variables that are only used during one function and then not needed anymore) alongside with alot of other changes, and I am not even sure if this update or something else is causing this. Might the "var" have caused it? Or what other reasons might this strange complication have?

• Best platform for android and ios game?

  - by LoveMeSomeCode

  Ok, this has been asked before, but not recently, and most of the answers were just 'buy a mac'. So we're a couple guys who've been making small flash games, and now we want to go mobile, and there seem to be lots of options. Does anyone here have experience with one or more of these platforms to tell us the pros and cons of each? Corona AIR 3 Rhodes Could someone with experience compare and contrast these to each other and native development? We want to cast the widest net with the least re-work so we'd like to target just Android and iPhone, and we'd like it to be an actual app in the market instead of just a mobile website. We have experience in Actionscript, Javascript, and C#.

• Local LINQtoSQL Database For Your Windows Phone 7 Application

  - by Tim Murphy

  There aren’t many applications that are of value without having some for of data store.  In Windows Phone development we have a few options.  You can store text directly to isolated storage.  You can also use a number of third party libraries to create or mimic databases in isolated storage.  With Mango we gained the ability to have a native .NET database approach which uses LINQ to SQL.  In this article I will try to bring together the components needed to implement this last type of data store and fill in some of the blanks that I think other articles have left out. Defining A Database The first things you are going to need to do is define classes that represent your tables and a data context class that is used as the overall database definition.  The table class consists of column definitions as you would expect.  They can have relationships and constraints as with any relational DBMS.  Below is an example of a table definition. First you will need to add some assembly references to the code file. using System.ComponentModel;using System.Data.Linq;using System.Data.Linq.Mapping; You can then add the table class and its associated columns.  It needs to implement INotifyPropertyChanged and INotifyPropertyChanging.  Each level of the class needs to be decorated with the attribute appropriate for that part of the definition.  Where the class represents the table the properties represent the columns.  In this example you will see that the column is marked as a primary key and not nullable with a an auto generated value. You will also notice that the in the column property’s set method It uses the NotifyPropertyChanging and NotifyPropertyChanged methods in order to make sure that the proper events are fired. [Table]public class MyTable: INotifyPropertyChanged, INotifyPropertyChanging{ public event PropertyChangedEventHandler PropertyChanged; private void NotifyPropertyChanged(string propertyName) { if(PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } public event PropertyChangingEventHandler PropertyChanging; private void NotifyPropertyChanging(string propertyName) { if(PropertyChanging != null) { PropertyChanging(this, new PropertyChangingEventArgs(propertyName)); } } private int _TableKey; [Column(IsPrimaryKey = true, IsDbGenerated = true, DbType = "INT NOT NULL Identity", CanBeNull = false, AutoSync = AutoSync.OnInsert)] public int TableKey { get { return _TableKey; } set { NotifyPropertyChanging("TableKey"); _TableKey = value; NotifyPropertyChanged("TableKey"); } } The last part of the database definition that needs to be created is the data context.  This is a simple class that takes an isolated storage location connection string its constructor and then instantiates tables as public properties. public class MyDataContext: DataContext{ public MyDataContext(string connectionString): base(connectionString) { MyRecords = this.GetTable<MyTable>(); } public Table<MyTable> MyRecords;} Creating A New Database Instance Now that we have a database definition it is time to create an instance of the data context within our Windows Phone app.  When your app fires up it should check if the database already exists and create an instance if it does not.  I would suggest that this be part of the constructor of your ViewModel. db = new MyDataContext(connectionString);if(!db.DatabaseExists()){ db.CreateDatabase();} The next thing you have to know is how the connection string for isolated storage should be constructed.  The main sticking point I have found is that the database cannot be created unless the file mode is read/write.  You may have different connection strings but the initial one needs to be similar to the following. string connString = "Data Source = 'isostore:/MyApp.sdf'; File Mode = read write"; Using you database Now that you have done all the up front work it is time to put the database to use.  To make your life a little easier and keep proper separation between your view and your viewmodel you should add a couple of methods to the viewmodel.  These will do the CRUD work of your application.  What you will notice is that the SubmitChanges method is the secret sauce in all of the methods that change data. private myDataContext myDb;private ObservableCollection<MyTable> _viewRecords;public ObservableCollection<MyTable> ViewRecords{ get { return _viewRecords; } set { _viewRecords = value; NotifyPropertyChanged("ViewRecords"); }}public void LoadMedstarDbData(){ var tempItems = from MyTable myRecord in myDb.LocalScans select myRecord; ViewRecords = new ObservableCollection<MyTable>(tempItems);}public void SaveChangesToDb(){ myDb.SubmitChanges();}public void AddMyTableItem(MyTable newScan){ myDb.LocalScans.InsertOnSubmit(newScan); myDb.SubmitChanges();}public void DeleteMyTableItem(MyTable newScan){ myDb.LocalScans.DeleteOnSubmit(newScan); myDb.SubmitChanges();} Updating existing database What happens when you need to change the structure of your database?  Unfortunately you have to add code to your application that checks the version of the database which over time will create some pollution in your codes base.  On the other hand it does give you control of the update.  In this example you will see the DatabaseSchemaUpdater in action.  Assuming we added a “Notes” field to the MyTable structure, the following code will check if the database is the latest version and add the field if it isn’t. if(!myDb.DatabaseExists()){ myDb.CreateDatabase();}else{ DatabaseSchemaUpdater dbUdater = myDb.CreateDatabaseSchemaUpdater(); if(dbUdater.DatabaseSchemaVersion < 2) { dbUdater.AddColumn<MyTable>("Notes"); dbUdater.DatabaseSchemaVersion = 2; dbUdater.Execute(); }} Summary This approach does take a fairly large amount of work, but I think the end product is robust and very native for .NET developers.  It turns out to be worth the investment. del.icio.us Tags: Windows Phone,Windows Phone 7,LINQ to SQL,LINQ,Database,Isolated Storage

• Cocoa Bindings in the face of a million of items in an NSArray

  - by François Beausoleil

  I'm writing a GUI for MongoDB using Cocoa. It's going well, but I don't know how to make KVO properties that would be lazily loaded. How does one handle that? For instance, viewing the documents in a Mongo collection. The collection might have a million items in it. I suspect I shouldn't be downloading the full 2-5 GiB of data to my Cocoa app, then format and display 20 rows. How does one implement that? I called my project Mongo Explorer, available on GitHub. Specifically, how would I code MECollection#reload to be lazy? Do I need to implement a data source delegate for my NSTableView?

• What's the difference between AppMobi and PhoneGap?

  - by Ajmal

  I am new to the cross platform application development. I came across the very similar cross platform frameworks AppMobi and PhoneGaP. I found the basic difference between appmobi and phonegap is appMobi offers a complete cloud-based development system that includes a the XDK development tool. ie It's possible to develop Apple apps without owning a Mac using appMobi. I want to know Is there any differences between apk/ipa created using Appmobi and apk/ipa created using PhoneGap? Is there any difference in native features that can be used ? Also other differences between these two.

• Using NPM to share resources between UI projects [on hold]

  - by guy mograbi

  I am a UI team leader. My team has a lot of projects using different languages/technologies. In some parts we will rewrite (gradually - @Ampt this is for you) the application in order to enable new fresh technologies in and get old dinosaurs out. I am going to use Node Package Manager to set up an "all powerful" build/dependency manager. Can I use NPM to depend on a private github repository? Can I use NPM to depend on SVN? Will NPM play nice with quickbuild? Since each project might have a slightly different structure (think jetty/maven or play!framework) can I configure NPM to install some dependencies in different folders while still running it from the project's root? How can I, using NPM, get development resources out and build a packaged product? (like a war) Yes/No - is there a reason to use grunt? No discussion, just one liners.

• Most Useful New Technology?

  - by Craig Ferguson

  I'm looking to take a sort of sabbatical, and I'd love to use it to learn a new technology. My question is this: What's the most useful "new" technology for a software engineer to use? Node.js, iOS programming, Android, something else? I'd prefer to stay away from anything too new or experimental, since those are, in my experience, rarely actually used in professional production environments (for better or worse). Does anyone happen to have stats on how many jobs there are for each new technology or have anecdotes about how fun each one is? I've been using python/Django, so that's out, and it's similar to Ruby so i don't think learning Ruby would be that useful to expanding my skills. Anyone have any other ideas?

  This is a sample code for getting Email accounts which are configured in Outlook 2007. This is developed using native code of VSTO. We can also implement is using 3rd party libraries like Redemption. Dim olAccounts As Outlook.Accounts = Globals.ThisAddIn.Application.ActiveExplorer().Session.Accounts Dim acc As Outlook.Account MessageBox.Show(“No. of accounts: ” & olAccounts.Count.ToString) If olAccounts.Count > 0 Then ReDim emails(olAccounts.Count) For Each acc In olAccounts MessageBox.Show(“Name: ” & acc.UserName & “Email: ” & acc.SmtpAddress) Marshal.ReleaseComObject(acc) Next Else MessageBox.Show(“There are no accounts in Outlook”) End If  Hope this helps!

• Is C++ indispensible for AAA game engines, as long as we have console-platform games? [closed]

  - by user1174924

  C++ has remained the industry standard for game engines much because of its features.. The primary reasons are(afaik): Technical reasons - High performance, native runtime, portibility, negligible latency, and more recently concurrency. Socio-Technical reasons - Availability of Libraries, Legecy stuff, most scripting languages on games have a good C api (ex lua), Good IDEs and most recently improved Development time.(C++11) Social reasons - People know C++, Licenced technologies, and battle proven. Does this make C++ for game engines indispensible, so long we have game consoles? Would not, the above features make me implement new graphics technology in C++ only? Edit: Will learning C++ garuntee me a job as a game engine dev In the future? I want to master every aspect of the language, but I already know C# and python. Should I allocate my time learning C++. I want to be a game engine developer.

• Virtualbox, How do I change guest (precise) resolution to 16:9 (1920x1080) instead of default 4:3?

  - by CHolmstedt

  There are many questions about resolution issues on askubuntu but no question/solution seems to solve my issue. I've a 12.04/precise host system and installed Ubuntu 12.04/precise as guest system as well. After installation I had the option of selecting 1024x768 (4:3) and 800x600 (4:3) as resolution in display settings. After installing guest additions the options 1280x960 (4:3) and 1440x1050 (4:3) was added to the list. Now 4 in total all having the 4:3 ratio. I then activated full screen mode (host+f) and got the guest running in native 1920x1200 (16:10) for my screen. After deactivating full screen two more options had been added to the resolutions dropdown list, 1920x1200 (16:10) and 1600x1200 (4:3). I want to run the guest in 1920x1080 (16:9) so I can easily record screencasts in "full-hd". Last time I had this problem the solution was to run "VBoxManage controlvm nameofyourVM setvideomodehint width height colordepth" command from the host but now I want to know if there is any easier way to solve this?

  I've got a Samsung Series 5 Chromebook which I've installed Ubuntu on. In Chrome OS the clickpad is working great but in ubuntu it hasn't got the same settings so I'm having problems with selcting text. I managed to find the setting in Chrome OS, it's 120 about lines of settings looking like this: Device 'SynPS/2 Synaptics TouchPad': Device Enabled (131): 1 Coordinate Transformation Matrix (133): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 Device Accel Profile (265): -1 Device Accel Constant Deceleration (266): 1.000000 Device Accel Adaptive Deceleration (267): 1.000000 Device Accel Velocity Scaling (268): 10.000000 Device Node (250): "/dev/input/event6" Now I would like to import these settings to Ubuntu. Is that possible?

• Adobe Air apps on the Mac App Store?

  - by coneybeare

  Before you chastise me for asking this, I have an Adobe Air app that has a lot of investment in it, and if there is a way to utilize the existing code-base in any way, it is worth considering. I have heard news reports in passing about Adobe creating some kind of tool to allow flash or air apps to be ported to native objective-c code, but the information found in google is mostly commentary on the one-time Apple blockade. My question(s) is/are this: Is it even possible, at any level, to use an existing Air app to create a Mac Store app? If possible, what are the resources I can use to accomplish this?
