  • New Sample Demonstrating the Traversing of Tree Bindings

    - by Duncan Mills
    A technique that I seem to use a fair amount, particularly in the construction of dynamic UIs is the use of a ADF Tree Binding to encode a multi-level master-detail relationship which is then expressed in the UI in some kind of looping form – usually a series of nested af:iterators, rather than the conventional tree or treetable. This technique exploits two features of the treebinding. First the fact that an treebinding can return both a collectionModel as well as a treeModel, this collectionModel can be used directly by an iterator. Secondly that the “rows” returned by the collectionModel themselves contain an attribute called .children. This attribute in turn gives access to a collection of all the children of that node which can also be iterated over. Putting this together you can represent the data encoded into a tree binding in all sorts of ways. As an example I’ve put together a very simple sample based on the HT schema and uploaded it to the ADF Sample project. It produces this UI: The important code is shown here for a Region -> Country -> Location Hierachy: <af:iterator id="i1" value="#{bindings.AllRegions.collectionModel}" var="rgn"> <af:showDetailHeader text="#{rgn.RegionName}" disclosed="true" id="sdh1"> <af:iterator id="i2" value="#{rgn.children}" var="cnty">     <af:showDetailHeader text="#{cnty.CountryName}" disclosed="true" id="sdh2">       <af:iterator id="i3" value="#{cnty.children}" var="loc">         <af:panelList id="pl1">         <af:outputText value="#{loc.City}" id="ot3"/>           </af:panelList>         </af:iterator>       </af:showDetailHeader>     </af:iterator>   </af:showDetailHeader> </af:iterator>  You can download the entire sample from here:

  • Seeking advice on tools and technology for my new game [closed]

    - by k.k. slider
    I'm a C# developer who has been programming a game in my spare time using XNA and Visual Studio. The game's logic is mostly done and I've completed a prototype that has most of the functionality of (what I envision to be) the final game. However, having heard about the uncertain future and (possibly) limited audience for XNA games, I'm looking to switch platforms... but I don't know what technology would best suit my needs. Below are some specifics about my game and what exactly I'm looking for, if you're interested: The game is a 2D turn-based tactical RPG (strategy game) for two players. It is a basic sprite and tile based game with animations and sound. 3D capabilities are not necessary. I'd like to allow players to compete with others online, and have a basic ranking/matchmaking system. I will probably need something that can interact with a server and a database (the game is turn-based and has no RNG, so cheating would be easy to detect even if most computation is done client-side and minimal data is sent to the server). Ideally, I would be able to release an early version of the game and have people give feedback as I develop additional features (similar to Minecraft). I'd prefer to have a way to release periodic updates to the game instead of releasing an absolute final product. To reach the widest possible audience, I'd prefer technology that allows me to release on PC, Android, iOS, and (maybe) Mac. This is a game with simple mouse inputs which can fit on a mobile touch screen. The game should be monetizable. If I find success with this game, then I may consider becoming a full-time indie game developer. I have several other game ideas and have learned quite a bit from my first attempt at game development. My first thought was an F2P/microtransaction model, but I'm open to other suggestions. Language isn't a primary concern of mine, since I have a decent amount of experience using several languages to program large projects. I'm willing to spend money (e.g. on a developer's license), but the more expensive it gets, the more hesitant I am to use it. I've looked into the following solutions... there are a LOT of tools out there... if anyone has experience with any of these and would like to recommend/reject any of them, it would be helpful. C#/.NET (XNA/MonoGame/SDL/SlimDX/Xamarin/ExEn/ANX?) HTML5/JS (AppMobi/PhoneGap/Marmalade/FlashCanvas/Cordova/libRocket?) Python (Pyglet/Pygame/Kivy?) Java (JavaFX/libGDX?) Unity/Construct 2/Cocos2D/NME/Corona/other game creation software? I'd like something that can do 2D and isn't limited by being too high-level. Other languages (Lua/LOVE? Moai?) Thanks for answering this rather long and tedious question...

  • how to get new site indexed by alexa

    - by JohnMerlino
    When I search my site on alexa, it says "Alexa Traffic Rank: No Data". So I google the issue. I come across this page: http://www.loudable.com/my-website-data-not-showing-in-alexa-get-your-website-crawled-by-alexasolution.html It says to get site indexed, click Crawl my site on the webmasters page. However there is no longer a link that says "Crawl my site". So as of now, does anyone know how to get site indexed by alexa so that my traffic rank will display on alexa index?

  • My new favourite traceflag

    - by Dave Ballantyne
    As we are all aware, there are a number of traceflags.  Some documented, some semi-documented and some completely undocumented.  Here is one that is undocumented that Paul White(b|t) mentioned almost as an aside in one of his excellent blog posts. Much has been written about residual predicates and how a predicate can be pushed into a seek/scan operation.  This is a good thing to happen,  it does save a lot of processing from having to be done.  For the uninitiated though: If we have a simple SELECT statement such as : the process that SQL Server goes through to resolve this is : The index IX_Person_LastName_FirstName_MiddleName is navigated to find the first “Smith” For each “Smith” the middle name is checked for being a null. Two operations!, and the execution plan doesnt fully represent all the work that is being undertaken. As you can see there is only a single seek operation, the work undertaken to resolve the condition “MiddleName is not null” has been pushed into it.  This can be seen in the properties. “Seek predicate” is how the index has been navigated, and “Predicate” is the condition run over every row,  a scan inside a seek!. So the question is:  How many rows have been resolved by the seek and how many by the scan ?  How many rows did the filter remove ? Wouldn’t it be nice if this operation could be split ?  That exactly what traceflag 9130 does. Executing the query: That changes the plan rather dramatically, and should be changing how we think about the index seek itself.  The Filter operator has been added and, unsurprisingly, the condition in this is “MiddleName is not null” So it is now evident that the seek operation found 103 Smiths and 60 of those Smiths had a non-null MiddleName. This traceflag has no place on a production system,  dont even think about it

  • Problem while adding a new value to a hashtable when it is enumerated

    - by karthik
    `hi I am doing a simple synchronous socket programming,in which i employed twothreads one for accepting the client and put the socket object into a collection,other thread will loop through the collection and send message to each client through the socket object. the problem is 1.i connect to clients to the server and start send messages 2.now i want to connect a new client,while doing this i cant update the collection and add a new client to my hashtable.it raises an exception "collection modified .Enumeration operation may not execute" how to add a NEW value without having problems in a hashtable. private void Listen() { try { //lblStatus.Text = "Server Started Listening"; while (true) { Socket ReceiveSock = ServerSock.Accept(); //keys.Clear(); ConnectedClients = new ListViewItem(); ConnectedClients.Text = ReceiveSock.RemoteEndPoint.ToString(); ConnectedClients.SubItems.Add("Connected"); ConnectedList.Items.Add(ConnectedClients); ClientTable.Add(ReceiveSock.RemoteEndPoint.ToString(), ReceiveSock); //foreach (System.Collections.DictionaryEntry de in ClientTable) //{ // keys.Add(de.Key.ToString()); //} //ClientTab.Add( //keys.Add( } //lblStatus.Text = "Client Connected Successfully."; } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void btn_receive_Click(object sender, EventArgs e) { Thread receiveThread = new Thread(new ThreadStart(Receive)); receiveThread.IsBackground = true; receiveThread.Start(); } private void Receive() { while (true) { //lblMsg.Text = ""; byte[] Byt = new byte[2048]; //ReceiveSock.Receive(Byt); lblMsg.Text = Encoding.ASCII.GetString(Byt); } } private void btn_Send_Click(object sender, EventArgs e) { Thread SendThread = new Thread(new ThreadStart(SendMsg)); SendThread.IsBackground = true; SendThread.Start(); } private void btnlist_Click(object sender, EventArgs e) { //Thread ListThread = new Thread(new ThreadStart(Configure)); //ListThread.IsBackground = true; //ListThread.Start(); } private void SendMsg() { while (true) { try { foreach (object SockObj in ClientTable.Keys) { byte[] Tosend = new byte[2048]; Socket s = (Socket)ClientTable[SockObj]; Tosend = Encoding.ASCII.GetBytes("FirstValue&" + GenerateRandom.Next(6, 10).ToString()); s.Send(Tosend); //ReceiveSock.Send(Tosend); Thread.Sleep(300); } } catch (Exception ex) { MessageBox.Show(ex.Message); } } }

  • How do I create a new usergroup?

    - by Sergiu
    I want to do this because I'm trying to fix user permissions from Ubuntu on my Mac OS X partition and Ubuntu doesn't have the "wheel" group that I so desperately need! Please don't trash me for this but I set my whole Mac OS X partition to give read and write access to everyone so I could access and modify everything on it from my dual-booting Ubuntu OS, and now everything is screwed... I don't have the original Mac OS X installation DVD and booting a Mac OS X 10.5.6 DVD gives me kernel panics... The OS installed on that Mac partition is 10.4.11. Is there any hope for me to ever fix it? I don't have money to buy utilities, and I can't use AppleJack either because my permissions are so messed up... None of the posted answers are what I wanted to do. I wanted to add fields to a user that was on my Mac partition, not a user part of the Ubuntu groups. Is that possible?

  • New Development Snapshot

    I finally did the work necessary to improve the codegen for finally handlers. More improvements are still possible, but at least most finally handlers will now execute without touching the exception object (and hence without having to do any mapping/stack trace collection work). It also means that assembly file sizes are a little bit smaller and that the debugging experience should be improved (less exception catching & rethrowing). Changes: ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • What's new at Oracle in Gamification?

    - by erikanollwebb
    It's been a crazy few weeks in Apps UX.  We are actively working on some gamification designs in now 4 different application product areas, as well as supporting some teams in other areas of Oracle.  Since that gets to be a pretty diverse group with a lot of resources and ideas, we've started a group in the Oracle Social Network on Gamification at Oracle.  That's limited to internal users at Oracle, but if you are interested in joining,  ping me directly for more information at [email protected]. We're planning another design jam like we did here at Oracle in May and at the Enterprise Gamification Forum in San Diego in September.  This time, we're taking the show to the UK, and hosting it with a group of customers on the Oracle Usability Advisory Board.  It should be a great event!   We're also actively designing some gamified flows which we'll be testing with users at the UKOUG to see what our customers think about some of our gamification ideas. We're looking at more feedback opportunities.  Internally, we surveyed 444 folks within Oracle about gamification and we'll be posting some of our findings on that here soon.  I'll be posting a blog on gamification for our customers at useableapps.oracle.com  in the next few weeks and I'll cross-post to here when it comes out.  So even though it's been quiet on this blog, we are busy and I'm hoping to push out more content in the next few weeks!  Would love to know what's most interesting to the folks reading so if there's something you especially want to see, feel free to comment or email me about it.

  • Template standard controls for an entirely new look and feel

    - by T
    This is the  Ineta Live player without the O’Data Feed.  It is a good example of taking the plain Media Player provided with the Encoder install and re-templating it to make it your own.  It also has a custom scrub control that is added in.  I generally put my tempates in a separate resource file.  On this project, I discovered that I had to include the template at the document level because I needed the ability to attach some code behind to fire change state behaviors.  I could not use the blend xaml behaviors for change state inside the template because the template can’ determine the TargetObject.   Version 1.01 – 6/10/09 (wow how did a week slip by)
