• How do I add array indices to the XML produced by JAXB?

  - by oconnor0

  I have a Java bean ala @XmlRootElement public class Bean { @XmlElementWrapper(name = "ints") @XmlElement(name = "int") int[] values; // constructors, getters, setters, etc... } JAXB is producing XML like <bean> <ints> <int>12</int> <int>34</int> <int>56</int> </ints> </bean> I would like the array indices to be included on the <int> tags as array position conveys important value. Preferably as attributes like <bean> <ints> <int id='0'>12</int> <int id='1'>34</int> <int id='2'>56</int> </ints> </bean> Is there a way to do this?

  - by uno

  Following this articlelink text one of the comments from 'zanoni' said he did it this way Using .NET 3.5: [XmlRoot] public class EmailConfiguration { [XmlElement] public string DataBoxID { get; set; } [XmlElement] public DefaultSendToAddressCollectionClass DefaultSendToAddressCollection { get; set; } } public class DefaultSendToAddressCollectionClass { [XmlElement] public string[] EmailAddress { get; set; } } How would I get my class to be as what he described? I ran the xsd tool and it is in the fashion as what shane posted in the above link [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)] [System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)] public partial class EmailConfiguration : object, System.ComponentModel.INotifyPropertyChanged { private string dataBoxIDField; private EmailConfigurationDefaultSendToAddressCollection[] defaultSendToAddressCollectionField; /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] public string DataBoxID { get { return this.dataBoxIDField; } set { this.dataBoxIDField = value; this.RaisePropertyChanged("DataBoxID"); } }

• How do I update the system wallpaper in an Android 1.6 service after changing it with setWallpaper()

  - by Majakk

  So basically the code "almost" works - the problem is that the system does not appear to know that the system wallpaper have been changed or does not do anything about it. Starting and closing another app manually appears to enforce an update. In an event call the following is done: getApplicationContext().setWallpaper(pWallOne); Is there some way of telling the android system to update the graphics or to do some cheap trick that forces it to? Any help or tip would be very much appreciated!!

• How do I return the value of the owner and id attributes respectively from an XML result set using P

  - by pharma_joe

  I am using PHP to iterate over the following result set, the aim is to build a hyperlink for each result using a foreach loop.

• Can you make a living as a system programmer?

  - by Helper Method

  Is there still a market for C system programmers? I love Java and some of the newer JVM languages but at the same time I really enjoy low-level system programming under Unix, using C and the GNU toolchain (it makes you feel elitist ;-)). Now I wonder a) is there still a market for C system programmers and b) how much do you earn compared to an app programmer c) is it that much fun in a large scale project?

• Using TXMLDocument to serialize form settings to XML and database.

  - by LukLed

  I have an interface: type IXMLSerializable = interface function SaveToXML : DOMString; function SaveToXMLDocument : IXMLDocument; procedure LoadFromXML(AXML : DOMString); end; It is used to serialize some settings of forms or frames to xml. Simple implementation: SaveToXMLDocument: function TSomething.SaveToXMLDocument: IXMLDocument; begin Result := TXMLDocument.Create(nil); with Result do begin Active := True; with AddChild(Self.Name) do begin AddChild(edSomeTextBox.Name).Attributes['Text'] := edSomeTextBox.Text; end; end; Result := XMLDoc; end; LoadFromXML: procedure TSomething.LoadFromXML(AXML: DOMString); var XMLDoc : IXMLDocument; I : Integer; begin XMLDoc := TXMLDocument.Create(nil); with XMLDoc do begin LoadFromXML(AXML); Active := True; with ChildNodes[0] do begin for I := 0 to ChildNodes.Count-1 do begin If ChildNodes[I].NodeName = 'edSomeTextBox' then edSomeTextBox.Text := ChildNodes[I].Attributes['Text']; end; end; end; end; SaveToXML: function TSomething.SaveToXML: DOMString; begin SaveToXMLDocument.SaveToXML(Result); end; DOMString result of SaveToXML is saved to database to blob field. I had some encoding issues with other implementations and this one works fine (right now). Do you see any dangers in this code? Can I have issues with different settings on various machines and systems?

• A way to ensure that a system tray icon is removed... guaranteed

  - by Brian R. Bondy

  Is there a way to guarantee that your system tray icon is removed? To add the system tray icon you do: Shell_NotifyIcon(NIM_ADD, &m_tnd); To remove the system tray icon you do: Shell_NotifyIcon(NIM_DELETE, &m_tnd); What I want to know: what if you application crashes? The icon stays in your system tray until you mouse over. Is there a way to guarantee that the icon will be removed, even when the application crashes? I would prefer not to use structured exception handling for various reasons. Another case that I want to handle is when the process is killed, but doesn't necessarily crash.

• How to get XML nodes content when names include special Characters?

  - by paoloi

  Im trying to navigate an XML block similar to this one ($doc) using PHP simplexml_load_string and using xpath on $doc to get only the 'Day' block like this: $myday = $doc->xpath ('//Day'); that lets me access all data from the block as an object, meaning $doc-AdultCount returns 1 and $doc-Id returns "6a0" however I can't access "SpecialDeals" content not using: $doc-SpecialDeals nor using: $doc-SpecialDeals-a:string Whats is the right syntax in this case? Thanks in advance. <Days> <DaysId>687</DaysId> <Day> <AdultsCount>1</AdultsCount> <Availability>Available</Availability> <Id>6a0</Id> <RoomType>Studio</RoomType> <SpecialDeals xmlns:a="http://microsoft.com/2003/Arrays"> <a:string>Best Day Ever</a:string> </SpecialDeals> </Day> <DaysPrice>247.4</DaysPrice> </Days>");

• How to split a string with negative numbers using ActionScript 3.0

  - by inzombiak

  I'm having trouble loading my level. I'm using Ogmo to create my level then I import it. I have no problem converting 0's and 1's into an Array, but I can't figure out how to do the same for -1's. It separates the "-" and the "1". Any help would be great. I've posted my code and the XML files below levelXML = new XML(e.target.data); playerX = int(levelXML.Entities.Player.@x); playerY = int(levelXML.Entities.Player.@y); levelGrid = levelXML.Grid; levelGrid = levelGrid.split("\n").join(""); levelTiles = levelXML.Tiles; levelTiles = levelTiles.split("\n").join(""); levelTiles = levelTiles.split(",").join(""); tileArray = levelTiles.split(""); gridArray = levelGrid.split(""); for(i = 0; i <= 34; i++) { levelArray[i] = new Array(); for(j = 0; j <= 34; j++) { if(tileArray[j*35 + i] == 0) { gridArray[j*35+i] = -1; } var currentSymbol = gridArray[j*35+i]; levelArray[i][j] = currentSymbol; if(gridArray[j*35 + i] == 1) { wall = new Wall; addChild(wall); wall.x = i*20 + 10; wall.y = j*20 + 10; } else if(gridArray[j*35 + i] == -1) { pellet = new Pellet; addChild(pellet); pellet.x = i*20 + 10; pellet.y = j*20 + 10; } } } I know the code is very dirty, but I needed a quick fix.

After some experimenting and some help from Glenn Block and his team mates I was able to track down the problem in ApplicationHost.config. Specifically the problem was that there were multiple *.svc mappings in the ApplicationHost.Config file and the older 2.0 runtime specific versions weren’t marked for the proper runtime. Because these handlers show up at the top of the list they execute first resulting in assembly load errors for the wrong version assembly. To fix this problem I ended up making a couple changes in applicationhost.config. On the machine level root’s Handler mappings I had an entry that looked like this:<add name="svc-Integrated" path="*.svc" verb="*" type="System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="integratedMode" /> and it needs to be changed to this:<add name="svc-Integrated" path="*.svc" verb="*" type="System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="integratedMode,runtimeVersionv2.0" />Notice the explicit runtime version assignment in the preCondition attribute which is key to keep ASP.NET 4.0 from executing that handler. The key here is that the runtime version needs to be set explicitly so that the various *.svc handlers don’t fire only in the order defined which in case of a .NET 4.0 app with the original setting would result in an incompatible version of System.ComponentModel to load.What was really hard to track this down is that even when looking in the debugger when launching the Web app, the AppDomain assembly loads showed System.ServiceModel V4.0 starting up just fine. Apparently the ASP.NET runtime load occurs at a different point and that’s when things break.So how did this break? According to the Microsoft folks it’s some older tools that got installed that change the default service handlers. There’s a blog entry that points at this problem with more detail:http://blogs.iis.net/webtopics/archive/2010/04/28/system-typeloadexception-for-system-servicemodel-activation-httpmodule-in-asp-net-4.aspxNote that I tried running aspnet_regiis and that did not fix the problem for me. I had to manually change the entries in applicationhost.config.   © Rick Strahl, West Wind Technologies, 2005-2011Posted in AJAX   ASP.NET  WCF

• Increasing System Menu Font Size for OS X Lion

  - by JW01

  My father-in-law recently picked up an iMac (with OS X 10.7 - Lion) and loves it. However, his eyesight isn't that great and would like to find a way to increase the font size of the system menu bar like he could on his old Windows system. I've been unable to find anything in the system configuration that might work. I've heard that the TinkerTool might be able to do it, but I'm a little hesitant to monkey around with his system - I don't want to introduce system stability issues. Question: Has anyone been able to find any good way to increase the system menu font size?

• How to publish an ASP.NET MVC application to a free host

  - by Lirik

  Hi, I'm using a free web host (0000free) which supports ASP.NET MVC, but it uses Mono. This is the first time I deploy an MVC application, so I'm a little confused as to where I need to deploy it. I have Visual Studio 2010 and I used its Publish Feature (i.e. right click on the project name and click publish) and I tried several things: Publish method: FTP to the root folder. Publish method: FTP to the publich_html folder. Publish method: File System to the root folder. Publish method: File System to the publich_html folder. Publish method: File System to a local directory on my computer and then FTP to root and also tried the public_html folder. I went into the cPanel (control panel) to try and see if ASP.NET has to be added/enabled for my web site, but I didn't see anything there. I can't browse to Index.aspx nor can I redirect to it from index.html (as suggested from other posts on the host forum), right now I have a link from index.html to Index.aspx but it's not working either (see http://www.mydevarmy.com) I've also tried renaming Index.aspx to Default.aspx, but that doesn't work either. The search utility of the forum of the host is somewhat weak, so I use google to search their forum: http://www.google.com/search?q=publish+asp.net+site%3A0000free.com%2Fforum%2F&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a I've been reading Pro ASP.NET MVC Framework and they have a chapter about publishing, but it doesn't provide any specific information with respect to the location of publishing, this is all they say (and it's not very helpful in my case): Where Should I Put My Application? You can deploy your application to any folder on the server. When IIS first installs, it automatically creates a folder for a web site called Default Web Site at c:\Inetpub\wwwroot\, but you shouldn’t feel any obligation to put your application files there. It’s very common to host applications on a different physical drive from the operating system (e.g., in e:\websites\ example.com). It’s entirely up to you, and may be influenced by concerns such as how you plan to back up the server. Here is the exception I get when I try to view my Index.aspx page: Unrecognized attribute 'targetFramework'. (/home/devarmy/public_html/Web.config line 1) Description: HTTP 500. Error processing request. Stack Trace: System.Configuration.ConfigurationErrorsException: Unrecognized attribute 'targetFramework'.

• A Simple Online Document Management System Using Asp.net MVC 3

  - by RazanPaul

  Nowadays we have a number of online file management systems (e.g. DropBox, SkyDrive and Google Drive). People can use them to manage different types of documents. However, one might need a system to manage documents when they do not want to publish the company documents to the cloud. In that case, they need to build an online document management system. This project is intended to meet this purpose. However, it is in the early stage. All the functionalities seem working. A lot of work is needed in the UI. Besides this, code needs refactoring. Please find the project at the following link: https://documentmanagementsystem.codeplex.com/

• Internet key not always detected by the operating system

  - by Carlo Gisonni

  I've over the time, tried and installed several versions of Ubuntu. Those versions I like more than others are: Lubuntu and Kubuntu. Everything seems to work properly but the Internet key. I do not know if it may depends on the weather, the moonphase or the tides but the Internet key is not always detected by the system and is sometimes very difficult to establish a connection when I do need to connect to internet. Without applyng any change sometimes works sometimes not. I've so far not found the solution and I think is a quite strange behaviour of the operating system as if the settings are wrong, should never work Awaiting a kind answer from those of you willing to help.

• Announcing the RTM of MvcExtensions (aka System.Web.Mvc.Extensibility)

  - by kazimanzurrashid

  I am proud to announce the v1.0 of MvcExtensions (previously known as System.Web.Extensibility). There has been quite a few changes and enhancements since the last release. Some of the major changes are: The Namespace has been changed to MvcExtensions from System.Web.Mvc.Extensibility to avoid the unnecessary confusion that it is in the .NET Framework or part of the ASP.NET MVC. The Project is now moved to CodePlex from the GitHub. The primary reason to start the project over GitHub was distributed version control which is no longer valid as CodePlex recently added the Mercurial support. There is nothing wrong with GitHub, it is an excellent place for managing your project. But CodePlex has always been the native place for .NET project. MVC 1.0 support has been dropped. I will be covering each features in my blog, so stay tuned!!!

• Mission critical embedded language

  - by Moe

  Maybe the question sounds a bit strange, so i'll explain a the background a little bit. Currently i'm working on a project at y university, which will be a complete on-board software for an satellite. The system is programmed in c++ on top of a real-time operating system. However, some subsystems like the attitude control system and the fault detection and a space simulation are currently only implemented in Matlab/Simulink, to prototype the algorithms efficiently. After their verification, they will be translated into c++. The complete on-board software grew very complex, and only a handful people know the whole system. Furthermore, many of the students haven't program in c++ yet and the manual memory management of c++ makes it even more difficult to write mission critical software. Of course the main system has to be implemented in c++, but i asked myself if it's maybe possible to use an embedded language to implement the subsystem which are currently written in Matlab. This embedded language should feature: static/strong typing and compiler checks to minimize runtime errors small memory usage, and relative fast runtime attitude control algorithms are mainly numerical computations, so a good numeric support would be nice maybe some sort of functional programming feature, matlab/simulink encourage you to use it too I googled a bit, but only found Lua. It looks nice, but i would not use it in mission critical software. Have you ever encountered a situation like this, or do you know any language, which could satisfies the conditions? EDIT: To clarify some things: embedded means it should be able to embed the language into the existing c++ environment. So no compiled languages like Ada or Haskell ;)

• What is a good way to store tilemap data?

  - by Stephen Tierney

  I'm developing a 2D platformer with some uni friends. We've based it upon the XNA Platformer Starter Kit which uses .txt files to store the tile map. While this is simple it does not give us enough control and flexibility with level design. Some examples: for multiple layers of content multiple files are required, each object is fixed onto the grid, doesn't allow for rotation of objects, limited number of characters etc. So I'm doing some research into how to store the level data and map file. This concerns only the file system storage of the tile maps, not the data structure to be used by the game while it is running. The tile map is loaded into a 2D array, so this question is about which source to fill the array from. Reasoning for DB: From my perspective I see less redundancy of data using a database to store the tile data. Tiles in the same x,y position with the same characteristics can be reused from level to level. It seems like it would simple enough to write a method to retrieve all the tiles that are used in a particular level from the database. Reasoning for JSON/XML: Visually editable files, changes can be tracked via SVN a lot easier. But there is repeated content. Do either have any drawbacks (load times, access times, memory etc) compared to the other? And what is commonly used in the industry? Currently the file looks like this: .................... .................... .................... .................... .................... .................... .................... .........GGG........ .........###........ .................... ....GGG.......GGG... ....###.......###... .................... .1................X. #################### 1 - Player start point, X - Level Exit, . - Empty space, # - Platform, G - Gem

  I am curently having ubuntu and win 7 dual boot and I want to delete my windows 7 and format all my partitions to use a linux file system. But I want to leave a door open in case I have any problems with linux, to be able to acces my linux file system with windows. I know that there are programs that can give you read-write acces to a ext2/3/4 FS (I tested none). I need advice in choosing the right FS, what are the diferences between ext 2/3/4 and what is the best software to do that.
