• How to implement smooth flocking

  - by Craig

  I'm working on a simple survival game, avoid the big guy and chase the the small guys to stay alive for as long as possible. I have taken the chase and evade example from MSDN create and drawn 20 mice on the screen. I want the small guys to flock when they arent evading. They are doing this, but it isnt as smooth as I would like it to be. How do i make the movement smoother? Its very jittery.# Below is what I have going at the moment, flocking code is within the IF statement, when it isnt set to evading. Any help would be greatly appreciated! :) namespace ChaseAndEvade { class MouseSprite { public enum MouseAiState { // evading the cat Evading, // the mouse can't see the "cat", and it's wandering around. Wander } // how fast can the mouse move? public float MaxMouseSpeed = 4.5f; // and how fast can it turn? public float MouseTurnSpeed = 0.20f; // MouseEvadeDistance controls the distance at which the mouse will flee from // cat. If the mouse is further than "MouseEvadeDistance" pixels away, he will // consider himself safe. public float MouseEvadeDistance = 100.0f; // this constant is similar to TankHysteresis. The value is larger than the // tank's hysteresis value because the mouse is faster than the tank: with a // higher velocity, small fluctuations are much more visible. public float MouseHysteresis = 60.0f; public Texture2D mouseTexture; public Vector2 mouseTextureCenter; public Vector2 mousePosition; public MouseAiState mouseState = MouseAiState.Wander; public float mouseOrientation; public Vector2 mouseWanderDirection; int separationImpact = 4; int cohesionImpact = 6; int alignmentImpact = 2; int sensorDistance = 50; public void UpdateMouse(Vector2 position, MouseSprite [] mice, int numberMice, int index) { Vector2 catPosition = position; int enemies = numberMice; // first, calculate how far away the mouse is from the cat, and use that // information to decide how to behave. If they are too close, the mouse // will switch to "active" mode - fleeing. if they are far apart, the mouse // will switch to "idle" mode, where it roams around the screen. // we use a hysteresis constant in the decision making process, as described // in the accompanying doc file. float distanceFromCat = Vector2.Distance(mousePosition, catPosition); // the cat is a safe distance away, so the mouse should idle: if (distanceFromCat > MouseEvadeDistance + MouseHysteresis) { mouseState = MouseAiState.Wander; } // the cat is too close; the mouse should run: else if (distanceFromCat < MouseEvadeDistance - MouseHysteresis) { mouseState = MouseAiState.Evading; } // if neither of those if blocks hit, we are in the "hysteresis" range, // and the mouse will continue doing whatever it is doing now. // the mouse will move at a different speed depending on what state it // is in. when idle it won't move at full speed, but when actively evading // it will move as fast as it can. this variable is used to track which // speed the mouse should be moving. float currentMouseSpeed; // the second step of the Update is to change the mouse's orientation based // on its current state. if (mouseState == MouseAiState.Evading) { // If the mouse is "active," it is trying to evade the cat. The evasion // behavior is accomplished by using the TurnToFace function to turn // towards a point on a straight line facing away from the cat. In other // words, if the cat is point A, and the mouse is point B, the "seek // point" is C. // C // B // A Vector2 seekPosition = 2 * mousePosition - catPosition; // Use the TurnToFace function, which we introduced in the AI Series 1: // Aiming sample, to turn the mouse towards the seekPosition. Now when // the mouse moves forward, it'll be trying to move in a straight line // away from the cat. mouseOrientation = ChaseAndEvadeGame.TurnToFace(mousePosition, seekPosition, mouseOrientation, MouseTurnSpeed); // set currentMouseSpeed to MaxMouseSpeed - the mouse should run as fast // as it can. currentMouseSpeed = MaxMouseSpeed; } else { // if the mouse isn't trying to evade the cat, it should just meander // around the screen. we'll use the Wander function, which the mouse and // tank share, to accomplish this. mouseWanderDirection and // mouseOrientation are passed by ref so that the wander function can // modify them. for more information on ref parameters, see // http://msdn2.microsoft.com/en-us/library/14akc2c7(VS.80).aspx ChaseAndEvadeGame.Wander(mousePosition, ref mouseWanderDirection, ref mouseOrientation, MouseTurnSpeed); // if the mouse is wandering, it should only move at 25% of its maximum // speed. currentMouseSpeed = .25f * MaxMouseSpeed; Vector2 separate = Vector2.Zero; Vector2 moveCloser = Vector2.Zero; Vector2 moveAligned = Vector2.Zero; // What the AI does when it sees other AIs for (int j = 0; j < enemies; j++) { if (index != j) { // Calculate a vector towards another AI Vector2 separation = mice[index].mousePosition - mice[j].mousePosition; // Only react if other AI is within a certain distance if ((separation.Length() < this.sensorDistance) & (separation.Length()> 0) ) { moveAligned += mice[j].mouseWanderDirection; float distance = Math.Abs(separation.Length()); if (distance == 0) distance = 1; moveCloser += mice[j].mousePosition; separation.Normalize(); separate += separation / distance; } } } if (moveAligned.LengthSquared() != 0) { moveAligned.Normalize(); } if (moveCloser.LengthSquared() != 0) { moveCloser.Normalize(); } moveCloser /= enemies; mice[index].mousePosition += (separate * separationImpact) + (moveCloser * cohesionImpact) + (moveAligned * alignmentImpact); } // The final step is to move the mouse forward based on its current // orientation. First, we construct a "heading" vector from the orientation // angle. To do this, we'll use Cosine and Sine to tell us the x and y // components of the heading vector. See the accompanying doc for more // information. Vector2 heading = new Vector2( (float)Math.Cos(mouseOrientation), (float)Math.Sin(mouseOrientation)); // by multiplying the heading and speed, we can get a velocity vector. the // velocity vector is then added to the mouse's current position, moving him // forward. mousePosition += heading * currentMouseSpeed; } } }

• Looking into the jQuery LazyLoad Plugin

  - by nikolaosk

  I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client side of web development.  You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery LazyLoad Plugin.If you want you can have a look at this post, where I describe the JQuery Cycle Plugin.You can find another post of mine talking about the JQuery Carousel Lite Plugin here. Another post of mine regarding the JQuery Image Zoom Plugin can be found here. You can have a look at the JQuery Overlays Plugin here . There are times when when I am asked to create a very long page with lots of images.My first thought is to enable paging on the proposed page. Imagine that we have 60 images on a page. There are performance concerns when we have so many images on a page. Paging can solve that problem if I am allowed to place only 5 images on a page.Sometimes the customer does not like the idea of the paging.Believe it or not some people find the idea of paging not attractive at all.In that case I need a way to only load the initial set of images and as the user scrolls down the page to load the rest.So as someone scrolls down new requests are made to the server and more images are fetched. I can accomplish that with the jQuery LazyLoad Plugin.This is just a plugin that delays loading of images in long web pages.The images that are outside of the viewport (visible part of web page) won't be loaded before the user scrolls to them. Using jQuery LazyLoad Plugin on long web pages containing many large images makes the page load faster. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like. You can use Visual Studio 2012 Express edition. You can download it here.  You can download this plugin from this link. I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5)<!DOCTYPE html><html lang="en">  <head>    <title>Liverpool Legends</title>    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>        <script type="text/javascript" src="jquery.lazyload.min.js" ></script></head>  <body>    <header>                <h1>Liverpool Legends</h1>    </header>        <div id="main">             <img src="barnes.JPG" width="800" height="1100" /><p />        <img src="dalglish.JPG" width="800" height="1100" /><p />                <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p />          </div>            <footer>        <p>All Rights Reserved</p>      </footer>                    <script type="text/javascript">                $(function () {                    $("img.LiverpoolImage").lazyload();                });        </script>     </body>  </html> This is a very simple markup. I have  added references to the JQuery library (current version is 1.8.3) and the JQuery LazyLoad Plugin. Firstly, I add two images         <img src="barnes.JPG" width="800" height="1100" /><p />        <img src="dalglish.JPG" width="800" height="1100" /><p />  that will load immediately as soon as the page loads. Then I add the images that will not load unless they become active in the viewport. I have all my img tags pointing the src attribute towards a placeholder image. I’m using a blank 1×1 px grey image,loader.gif.The five images that will load as the user scrolls down the page follow.         <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p /> Then we need to rename the image src to point towards the proper image placeholder. The full image URL goes into the data-original attribute.The Javascript code that makes it all happen follows. We need to make a call to the JQuery LazyLoad Plugin. We add the script just before we close the body element.         <script type="text/javascript">                $(function () {                    $("img.LiverpoolImage").lazyload();                });        </script>We can change the code above to incorporate some effects.          <script type="text/javascript">  $("img.LiverpoolImage").lazyload({    effect: "fadeIn"  });    </script> That is all I need to write to achieve lazy loading. It it true that you can do so much with less!!I view my simple page in Internet Explorer 10 and it works as expected. I have tested this simple solution in all major browsers and it works fine. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

• Notes on implementing Visual Studio 2010 Navigate To

  - by cyberycon

  One of the many neat functions added to Visual Studio in VS 2010 was the Navigate To feature. You can find it by clicking Edit, Navigate To, or by using the keyboard shortcut Ctrl, (yes, that's control plus the comma key). This pops up the Navigate To dialog that looks like this: As you type, Navigate To starts searching through a number of different search providers for your term. The entries in the list change as you type, with most providers doing some kind of fuzzy or at least substring matching. If you have C#, C++ or Visual Basic projects in your solution, all symbols defined in those projects are searched. There's also a file search provider, which displays all matching filenames from projects in the current solution as well. And, if you have a Visual Studio package of your own, you can implement a provider too. Micro Focus (where I work) provide the Visual COBOL language inside Visual Studio (http://visualstudiogallery.msdn.microsoft.com/ef9bc810-c133-4581-9429-b01420a9ea40 ), and we wanted to provide this functionality too. This post provides some notes on the things I discovered mainly through trial and error, but also with some kind help from devs inside Microsoft. The expectation of Navigate To is that it searches across the whole solution, not just the current project. So in our case, we wanted to search for all COBOL symbols inside all of our Visual COBOL projects inside the solution. So first of all, here's the Microsoft documentation on Navigate To: http://msdn.microsoft.com/en-us/library/ee844862.aspx . It's the reference information on the Microsoft.VisualStudio.Language.NavigateTo.Interfaces Namespace, and it lists all the interfaces you will need to implement to create your own Navigate To provider. Navigate To uses Visual Studio's latest mechanism for integrating external functionality and services, Managed Extensibility Framework (MEF). MEF components don't require any registration with COM or any other registry entries to be found by Visual Studio. Visual Studio looks in several well-known locations for manifest files (extension.vsixmanifest). It then uses reflection to scan for MEF attributes on classes in the assembly to determine which functionality the assembly provides. MEF itself is actually part of the .NET framework, and you can learn more about it here: http://mef.codeplex.com/. To get started with Visual Studio and MEF you could do worse than look at some of the editor examples on the VSX page http://archive.msdn.microsoft.com/vsx . I've also written a small application to help with switching between development and production MEF assemblies, which you can find on Codeproject: http://www.codeproject.com/KB/miscctrl/MEF_Switch.aspx. The Navigate To interfaces Back to Navigate To, and summarizing the MSDN reference documentation, you need to implement the following interfaces: INavigateToItemProviderFactoryThis is Visual Studio's entry point to your Navigate To implementation, and you must decorate your implementation with the following MEF export attribute: [Export(typeof(INavigateToItemProviderFactory))]  INavigateToItemProvider Your INavigateToItemProviderFactory needs to return your implementation of INavigateToItemProvider. This class implements StartSearch() and StopSearch(). StartSearch() is the guts of your provider, and we'll come back to it in a minute. This object also needs to implement IDisposeable(). INavigateToItemDisplayFactory Your INavigateToItemProvider hands back NavigateToItems to the NavigateTo framework. But to give you good control over what appears in the NavigateTo dialog box, these items will be handed back to your INavigateToItemDisplayFactory, which must create objects implementing INavigateToItemDisplay  INavigateToItemDisplay Each of these objects represents one result in the Navigate To dialog box. As well as providing the description and name of the item, this object also has a NavigateTo() method that should be capable of displaying the item in an editor when invoked. Carrying out the search The lifecycle of your INavigateToItemProvider is the same as that of the Navigate To dialog. This dialog is modal, which makes your implementation a little easier because you know that the user can't be changing things in editors and the IDE while this dialog is up. But the Navigate To dialog DOES NOT run on the main UI thread of the IDE – so you need to be aware of that if you want to interact with editors or other parts of the IDE UI. When the user invokes the Navigate To dialog, your INavigateToItemProvider gets sent a TryCreateNavigateToItemProvider() message. Instantiate your INavigateToItemProvider and hand this back. The sequence diagram below shows what happens next. Your INavigateToItemProvider will get called with StartSearch(), and passed an INavigateToCallback. StartSearch() is an asynchronous request – you must return from this method as soon as possible, and conduct your search on a separate thread. For each match to the search term, instantiate a NavigateToItem object and send it to INavigateToCallback.AddItem(). But as the user types in the Search Terms field, NavigateTo will invoke your StartSearch() method repeatedly with the changing search term. When you receive the next StartSearch() message, you have to abandon your current search, and start a new one. You can't rely on receiving a StopSearch() message every time. Finally, when the Navigate To dialog box is closed by the user, you will get a Dispose() message – that's your cue to abandon any uncompleted searches, and dispose any resources you might be using as part of your search. While you conduct your search invoke INavigateToCallback.ReportProgress() occasionally to provide feedback about how close you are to completing the search. There does not appear to be any particular requirement to how often you invoke ReportProgress(), and you report your progress as the ratio of two integers. In my implementation I report progress in terms of the number of symbols I've searched over the total number of symbols in my dictionary, and send a progress report every 16 symbols. Displaying the Results The Navigate to framework invokes INavigateToItemDisplayProvider.CreateItemDisplay() once for each result you passed to the INavigateToCallback. CreateItemDisplay() is passed the NavigateToItem you handed to the callback, and must return an INavigateToItemDisplay object. NavigateToItem is a sealed class which has a few properties, including the name of the symbol. It also has a Tag property, of type object. This enables you to stash away all the information you will need to create your INavigateToItemDisplay, which must implement an INavigateTo() method to display a symbol in an editor IDE when the user double-clicks an entry in the Navigate To dialog box. Since the tag is of type object, it is up to you, the implementor, to decide what kind of object you store in here, and how it enables the retrieval of other information which is not included in the NavigateToItem properties. Some of the INavigateToItemDisplay properties are self-explanatory, but a couple of them are less obvious: Additional informationThe string you return here is displayed inside brackets on the same line as the Name property. In English locales, Visual Studio includes the preposition "of". If you look at the first line in the Navigate To screenshot at the top of this article, Book_WebRole.Default is the additional information for textBookAuthor, and is the namespace qualified type name the symbol appears in. For procedural COBOL code we display the Program Id as the additional information DescriptionItemsYou can use this property to return any textual description you want about the item currently selected. You return a collection of DescriptionItem objects, each of which has a category and description collection of DescriptionRun objects. A DescriptionRun enables you to specify some text, and optional formatting, so you have some control over the appearance of the displayed text. The DescriptionItems property is displayed at the bottom of the Navigate To dialog box, with the Categories on the left and the Descriptions on the right. The Visual COBOL implementation uses it to display more information about the location of an item, making it easier for the user to know disambiguate duplicate names (something there can be a lot of in large COBOL applications). Summary I hope this article is useful for anyone implementing Navigate To. It is a fantastic navigation feature that Microsoft have added to Visual Studio, but at the moment there still don't seem to be any examples on how to implement it, and the reference information on MSDN is a little brief for anyone attempting an implementation.

• Project Jigsaw: Late for the train: The Q&A

  - by Mark Reinhold

  I recently proposed, to the Java community in general and to the SE 8 (JSR 337) Expert Group in particular, to defer Project Jigsaw from Java 8 to Java 9. I also proposed to aim explicitly for a regular two-year release cycle going forward. Herewith a summary of the key questions I’ve seen in reaction to these proposals, along with answers. Making the decision Q Has the Java SE 8 Expert Group decided whether to defer the addition of a module system and the modularization of the Platform to Java SE 9? A No, it has not yet decided. Q By when do you expect the EG to make this decision? A In the next month or so. Q How can I make sure my voice is heard? A The EG will consider all relevant input from the wider community. If you have a prominent blog, column, or other communication channel then there’s a good chance that we’ve already seen your opinion. If not, you’re welcome to send it to the Java SE 8 Comments List, which is the EG’s official feedback channel. Q What’s the overall tone of the feedback you’ve received? A The feedback has been about evenly divided as to whether Java 8 should be delayed for Jigsaw, Jigsaw should be deferred to Java 9, or some other, usually less-realistic, option should be taken. Project Jigsaw Q Why is Project Jigsaw taking so long? A Project Jigsaw started at Sun, way back in August 2008. Like many efforts during the final years of Sun, it was not well staffed. Jigsaw initially ran on a shoestring, with just a handful of mostly part-time engineers, so progress was slow. During the integration of Sun into Oracle all work on Jigsaw was halted for a time, but it was eventually resumed after a thorough consideration of the alternatives. Project Jigsaw was really only fully staffed about a year ago, around the time that Java 7 shipped. We’ve added a few more engineers to the team since then, but that can’t make up for the inadequate initial staffing and the time lost during the transition. Q So it’s really just a matter of staffing limitations and corporate-integration distractions? A Aside from these difficulties, the other main factor in the duration of the project is the sheer technical difficulty of modularizing the JDK. Q Why is modularizing the JDK so hard? A There are two main reasons. The first is that the JDK code base is deeply interconnected at both the API and the implementation levels, having been built over many years primarily in the style of a monolithic software system. We’ve spent considerable effort eliminating or at least simplifying as many API and implementation dependences as possible, so that both the Platform and its implementations can be presented as a coherent set of interdependent modules, but some particularly thorny cases remain. Q What’s the second reason? A We want to maintain as much compatibility with prior releases as possible, most especially for existing classpath-based applications but also, to the extent feasible, for applications composed of modules. Q Is modularizing the JDK even necessary? Can’t you just put it in one big module? A Modularizing the JDK, and more specifically modularizing the Java SE Platform, will enable standard yet flexible Java runtime configurations scaling from large servers down to small embedded devices. In the long term it will enable the convergence of Java SE with the higher-end Java ME Platforms. Q Is Project Jigsaw just about modularizing the JDK? A As originally conceived, Project Jigsaw was indeed focused primarily upon modularizing the JDK. The growing demand for a truly standard module system for the Java Platform, which could be used not just for the Platform itself but also for libraries and applications built on top of it, later motivated expanding the scope of the effort. Q As a developer, why should I care about Project Jigsaw? A The introduction of a modular Java Platform will, in the long term, fundamentally change the way that Java implementations, libraries, frameworks, tools, and applications are designed, built, and deployed. Q How much progress has Project Jigsaw made? A We’ve actually made a lot of progress. Much of the core functionality of the module system has been prototyped and works at both compile time and run time. We’ve extended the Java programming language with module declarations, worked out a structure for modular source trees and corresponding compiled-class trees, and implemented these features in javac. We’ve defined an efficient module-file format, extended the JVM to bootstrap a modular JRE, and designed and implemented a preliminary API. We’ve used the module system to make a good first cut at dividing the JDK and the Java SE API into a coherent set of modules. Among other things, we’re currently working to retrofit the java.util.ServiceLoader API to support modular services. Q I want to help! How can I get involved? A Check out the project page, read the draft requirements and design overview documents, download the latest prototype build, and play with it. You can tell us what you think, and follow the rest of our work in real time, on the jigsaw-dev list. The Java Platform Module System JSR Q What’s the relationship between Project Jigsaw and the eventual Java Platform Module System JSR? A At a high level, Project Jigsaw has two phases. In the first phase we’re exploring an approach to modularity that’s markedly different from that of existing Java modularity solutions. We’ve assumed that we can change the Java programming language, the virtual machine, and the APIs. Doing so enables a design which can strongly enforce module boundaries in all program phases, from compilation to deployment to execution. That, in turn, leads to better usability, diagnosability, security, and performance. The ultimate goal of the first phase is produce a working prototype which can inform the work of the Module-System JSR EG. Q What will happen in the second phase of Project Jigsaw? A The second phase will produce the reference implementation of the specification created by the Module-System JSR EG. The EG might ultimately choose an entirely different approach than the one we’re exploring now. If and when that happens then Project Jigsaw will change course as necessary, but either way I think that the end result will be better for having been informed by our current work. Maven & OSGi Q Why not just use Maven? A Maven is a software project management and comprehension tool. As such it can be seen as a kind of build-time module system but, by its nature, it does nothing to support modularity at run time. Q Why not just adopt OSGi? A OSGi is a rich dynamic component system which includes not just a module system but also a life-cycle model and a dynamic service registry. The latter two facilities are useful to some kinds of sophisticated applications, but I don’t think they’re of wide enough interest to be standardized as part of the Java SE Platform. Q Okay, then why not just adopt the module layer of OSGi? A The OSGi module layer is not operative at compile time; it only addresses modularity during packaging, deployment, and execution. As it stands, moreover, it’s useful for library and application modules but, since it’s built strictly on top of the Java SE Platform, it can’t be used to modularize the Platform itself. Q If Maven addresses modularity at build time, and the OSGi module layer addresses modularity during deployment and at run time, then why not just use the two together, as many developers already do? A The combination of Maven and OSGi is certainly very useful in practice today. These systems have, however, been built on top of the existing Java platform; they have not been able to change the platform itself. This means, among other things, that module boundaries are weakly enforced, if at all, which makes it difficult to diagnose configuration errors and impossible to run untrusted code securely. The prototype Jigsaw module system, by contrast, aims to define a platform-level solution which extends both the language and the JVM in order to enforce module boundaries strongly and uniformly in all program phases. Q If the EG chooses an approach like the one currently being taken in the Jigsaw prototype, will Maven and OSGi be made obsolete? A No, not at all! No matter what approach is taken, to ensure wide adoption it’s essential that the standard Java Platform Module System interact well with Maven. Applications that depend upon the sophisticated features of OSGi will no doubt continue to use OSGi, so it’s critical that implementations of OSGi be able to run on top of the Java module system and, if suitably modified, support OSGi bundles that depend upon Java modules. Ideas for how to do that are currently being explored in Project Penrose. Java 8 & Java 9 Q Without Jigsaw, won’t Java 8 be a pretty boring release? A No, far from it! It’s still slated to include the widely-anticipated Project Lambda (JSR 335), work on which has been going very well, along with the new Date/Time API (JSR 310), Type Annotations (JSR 308), and a set of smaller features already in progress. Q Won’t deferring Jigsaw to Java 9 delay the eventual convergence of the higher-end Java ME Platforms with Java SE? A It will slow that transition, but it will not stop it. To allow progress toward that convergence to be made with Java 8 I’ve suggested to the Java SE 8 EG that we consider specifying a small number of Profiles which would allow compact configurations of the SE Platform to be built and deployed. Q If Jigsaw is deferred to Java 9, would the Oracle engineers currently working on it be reassigned to other Java 8 features and then return to working on Jigsaw again after Java 8 ships? A No, these engineers would continue to work primarily on Jigsaw from now until Java 9 ships. Q Why not drop Lambda and finish Jigsaw instead? A Even if the engineers currently working on Lambda could instantly switch over to Jigsaw and immediately become productive—which of course they can’t—there are less than nine months remaining in the Java 8 schedule for work on major features. That’s just not enough time for the broad review, testing, and feedback which such a fundamental change to the Java Platform requires. Q Why not ship the module system in Java 8, and then modularize the platform in Java 9? A If we deliver a module system in one release but don’t use it to modularize the JDK until some later release then we run a big risk of getting something fundamentally wrong. If that happens then we’d have to fix it in the later release, and fixing fundamental design flaws after the fact almost always leads to a poor end result. Q Why not ship Jigsaw in an 8.5 release, less than two years after 8? Or why not just ship a new release every year, rather than every other year? A Many more developers work on the JDK today than a couple of years ago, both because Oracle has dramatically increased its own investment and because other organizations and individuals have joined the OpenJDK Community. Collectively we don’t, however, have the bandwidth required to ship and then provide long-term support for a big JDK release more frequently than about every other year. Q What’s the feedback been on the two-year release-cycle proposal? A For just about every comment that we should release more frequently, so that new features are available sooner, there’s been another asking for an even slower release cycle so that large teams of enterprise developers who ship mission-critical applications have a chance to migrate at a comfortable pace.

• CSC folder data access AND roaming profiles issues (Vista with Server 2003, then 2008)

  - by Alex Jones

  I'm a junior sysadmin for an IT contractor that helps small, local government agencies, like little towns and the like. One of our clients, a public library with ~ 50 staff users, was recently migrated from Server 2003 Standard to Server 2008 R2 Standard in a very short timeframe; our senior employee, the only network engineer, had suddenly put in his two weeks notice, so management pushed him to do this project before quitting. A bit hasty on management's part? Perhaps. Could we do anything about that? Nope. Do I have to fix this all by myself? Pretty much. The network is set up like this: a) 50ish staff workstations, all running Vista Business SP2. All staff use MS Outlook, which uses RPC-over-HTTPS ("Outlook Anywhere") for cached Exchange access to an offsite location. b) One new (virtualized) Server 2008 R2 Standard instance, running atop a Server 2008 R2 host via Hyper-V. The VM is the domain's DC, and also the site's one and only file server. Let's call that VM "NEWBOX". c) One old physical Server 2003 Standard server, running the same roles. Let's call it "OLDBOX". It's still on the network and accessible, but it's been demoted, and its shares have been disabled. No data has been deleted. c) Gigabit Ethernet everywhere. The organization's only has one domain, and it did not change during the migration. d) Most users were set up for a combo of redirected folders + offline files, but some older employees who had been with the organization a long time are still on roaming profiles. To sum up: the servers in question handle user accounts and files, nothing else (eg, no TS, no mail, no IIS, etc.) I have two major problems I'm hoping you can help me with: 1) Even though all domain users have had their redirected folders moved to the new server, and loggin in to their workstations and testing confirms that the Documents/Music/Whatever folders point to the new paths, it appears some users (not laptops or anything either!) had been working offline from OLDBOX for a long time, and nobody realized it. Here's the ugly implication: a bunch of their data now lives only in their CSC folders, because they can't access the share on OLDBOX and sync with it finally. How do I get this data out of those CSC folders, and onto NEWBOX? 2) What's the best way to migrate roaming profile users to non-roaming ones, without losing vital data like documents, any lingering PSTs, etc? Things I've thought about trying: For problem 1: a) Reenable the documents share on OLDBOX, force an Offline Files sync for ALL domain users, then copy OLDBOX's share's data to the equivalent share on NEWBOX. Reinitialize the Offline Files cache for every user. With this: How do I safely force a domain-wide Offline Files sync? Could I lose data by reenabling the share on OLDBOX and forcing the sync? Afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? b) Determine which users have unsynced changes to OLDBOX (again, how?), search each user's CSC folder domain-wide via workstation admin shares, and grab the unsynched data. Reinitialize the Offline Files cache for every user. With this: How can I detect which users have unsynched changes with a script? How can I search each user's CSC folder, when the ownership and permissions set for CSC folders are so restrictive? Again, afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? c) Manually visit each workstation, copy the contents of the CSC folder, and manually copy that data onto NEWBOX. Reinitialize the Offline Files cache for every user. With this: Again, how do I 'break into' the CSC folder and get to its data? As an experiment, I took one workstation's HD offsite, imaged it for safety, and then tried the following with one of our shop PCs, after attaching the drive: grant myself full control of the folder (failed), grant myself ownership of the folder (failed), run chkdsk on the whole drive to make sure nothing's messed up (all OK), try to take full control of the entire drive (failed), try to take ownership of the entire drive (failed) MS KB articles and Googling around suggests there's a utility called CSCCMD that's meant for this exact scenario...but it looks like it's available for XP, not Vista, no? Again, afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? For problem 2: a) Figure out which users are on roaming profiles, and where their profiles 'live' on the server. Create new folders for them in the redirected folders repository, migrate existing data, and disable the roaming. With this: Finding out who's roaming isn't hard. But what's the best way to disable the roaming itself? In AD Users and Computers, or on each user's workstation? Doing it centrally on the server seems more efficient; that said, all of the KB research I've done turns up articles on how to go from local to roaming, not the other way around, so I don't have good documentation on this. In closing: we have good backups of NEWBOX and OLDBOX, but not of the workstations themselves, so anything drastic on the client side would need imaging and testing for safety. Thanks for reading along this far! Hopefully you can help me dig us out of this mess.

• Stumbling Through: Visual Studio 2010 (Part III)

  The last post ended with us just getting started on stumbling into text template file customization, a task that required a Visual Studio extension (Tangible T4 Editor) to even have a chance at completing.  Despite the benefits of the Tangible T4 Editor, I still had a hard time putting together a solid text template that would be easy to explain.  This is mostly due to the way the files allow you to mix code (encapsulated in <# #>) with straight-up text to generate.  It is effective to be sure, but not very readable.  Nevertheless, I will try and explain what was accomplished in my custom tt file, though the details of which are not really the point of this article (my way of saying dont criticize my crappy code, and certainly dont use it in any somewhat real application.  You may become dumber just by looking at this code.  You have been warned really the footnote I should put at the end of all of my blog posts). To begin with, there were two basic requirements that I needed the code generator to satisfy:  Reading one to many entity framework files, and using the entities that were found to write one to many class files.  Thankfully, using the Entity Object Generator as a starting point gave us an example on how to do exactly that by using the MetadataLoader and EntityFrameworkTemplateFileManager you include references to these items and use them like so: // Instantiate an entity framework file reader and file writer MetadataLoader loader = new MetadataLoader(this); EntityFrameworkTemplateFileManager fileManager = EntityFrameworkTemplateFileManager.Create(this); // Load the entity model metadata workspace MetadataWorkspace metadataWorkspace = null; bool allMetadataLoaded =loader.TryLoadAllMetadata("MFL.tt", out metadataWorkspace); EdmItemCollection ItemCollection = (EdmItemCollection)metadataWorkspace.GetItemCollection(DataSpace.CSpace); // Create an IO class to contain the 'get' methods for all entities in the model fileManager.StartNewFile("MFL.IO.gen.cs"); Next, we want to be able to loop through all of the entities found in the model, and then each property for each entity so we can generate classes and methods for each.  The code for that is blissfully simple: // Iterate through each entity in the model foreach (EntityType entity in ItemCollection.GetItems<EntityType>().OrderBy(e => e.Name)) {     // Iterate through each primitive property of the entity     foreach (EdmProperty edmProperty in entity.Properties.Where(p => p.TypeUsage.EdmType is PrimitiveType && p.DeclaringType == entity))     {         // TODO:  Create properties     }     // Iterate through each relationship of the entity     foreach (NavigationProperty navProperty in entity.NavigationProperties.Where(np => np.DeclaringType == entity))     {         // TODO:  Create associations     } } There really isnt anything more advanced than that going on in the text template the only thing I had to blunder through was realizing that if you want the generator to interpret a line of code (such as our iterations above), you need to enclose the code in <# and #> while if you want the generator to interpret the VALUE of code, such as putting the entity name into the class name, you need to enclose the code in <#= and #> like so: public partial class <#=entity.Name#> To make a long story short, I did a lot of repetition of the above to come up with a text template that generates a class for each entity based on its properties, and a set of IO methods for each entity based on its relationships.  The two work together to provide lazy-loading for hierarchical data (such getting Team.Players) so it should be pretty intuitive to use on a front-end.  This text template is available here you can tweak the inputFiles array to load one or many different edmx models and generate the basic xml IO and class files, though it will probably only work correctly in the simplest of cases, like our MFL model described in the previous post.  Additionally, there is no validation, logging or error handling which is something I want to handle later by stumbling through the enterprise library 5.0. The code that gets generated isnt anything special, though using the LINQ to XML feature was something very new and exciting for me I had only worked with XML in the past using the DOM or XML Reader objects along with XPath, and the LINQ to XML model is just so much more elegant and supposedly efficient (something to test later).  For example, the following code was generated to create a Player object for each Player node in the XML:         return from element in GetXmlData(_PlayerDataFile).Descendants("Player")             select new Player             {                 Id = int.Parse(element.Attribute("Id").Value)                 ,ParentName = element.Parent.Name.LocalName                 ,ParentId = long.Parse(element.Parent.Attribute("Id").Value)                 ,Name = element.Attribute("Name").Value                 ,PositionId = int.Parse(element.Attribute("PositionId").Value)             }; It is all done in one line of code, no looping needed.  Even though GetXmlData loads the entire xml file just like the old XML DOM approach would have, it is supposed to be much less resource intensive.  I will definitely put that to the test after we develop a user interface for getting at this data.  Speaking of the data where IS the data?  Weve put together a pretty model and a bunch of code around it, but we dont have any data to speak of.  We can certainly drop to our favorite XML editor and crank out some data, but if it doesnt totally match our model, it will not load correctly.  To help with this, Ive built in a method to generate xml at any given layer in the hierarchy.  So for us to get the closest possible thing to real data, wed need to invoke MFL.IO.GenerateTeamXML and save the results to file.  Doing so should get us something that looks like this: <Team Id="0" Name="0">   <Player Id="0" Name="0" PositionId="0">     <Statistic Id="0" PassYards="0" RushYards="0" Year="0" />   </Player> </Team> Sadly, it is missing the Positions node (havent thought of a way to generate lookup xml yet) and the data itself isnt quite realistic (well, as realistic as MFL data can be anyway).  Lets manually remedy that for now to give us a decent starter set of data.  Note that this is TWO xml files Lookups.xml and Teams.xml: <Lookups Id=0>   <Position Id="0" Name="Quarterback"/>   <Position Id="1" Name="Runningback"/> </Lookups> <Teams Id=0>   <Team Id="0" Name="Chicago">     <Player Id="0" Name="QB Bears" PositionId="0">       <Statistic Id="0" PassYards="4000" RushYards="120" Year="2008" />       <Statistic Id="1" PassYards="4200" RushYards="180" Year="2009" />     </Player>     <Player Id="1" Name="RB Bears" PositionId="1">       <Statistic Id="2" PassYards="0" RushYards="800" Year="2007" />       <Statistic Id="3" PassYards="0" RushYards="1200" Year="2008" />       <Statistic Id="4" PassYards="3" RushYards="1450" Year="2009" />     </Player>   </Team> </Teams> Ok, so we have some data, we have a way to read/write that data and we have a friendly way of representing that data.  Now, what remains is the part that I have been looking forward to the most: present the data to the user and give them the ability to add/update/delete, and doing so in a way that is very intuitive (easy) from a development standpoint.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  - by polonskyg

  I'm trying to add SignalR to my project (ASPNET MVC 4). But I can't make it work. In the below image you can see the error I'm receiving. I've read a lot of stackoverflow posts but none of them is resolving my issue. This is what I did so far: 1) Ran Install-Package Microsoft.AspNet.SignalR -Pre 2) Added RouteTable.Routes.MapHubs(); in Global.asax.cs Application_Start() 3) If I go to http://localhost:9096/Gdp.IServer.Web/signalr/hubs I can see the file content 4) Added <modules runAllManagedModulesForAllRequests="true"/> to Web.Config 5) Created folder Hubs in the root of the MVC application 6) Moved jquery and signalR scripts to /Scripts/lib folder (I'm not using jquery 1.6.4, I'm using the latest) This is my Index.cshtml <h2>List of Messages</h2> <div class="container"> <input type="text" id="message" /> <input type="button" id="sendmessage" value="Send" /> <input type="hidden" id="displayname" /> <ul id="discussion"> </ul> </div> @section pageScripts { <!--Reference the SignalR library. --> <script src="@Url.Content("~/Scripts/jquery.signalR-1.0.0-rc1.min.js")" type="text/javascript"></script> <!--Reference the autogenerated SignalR hub script. --> <script type="text/javascript" src="~/signalr/hubs"></script> <script src="@Url.Content("~/Scripts/map.js")" type="text/javascript"></script> } This is my IServerHub.cs file (located inside Hubs folder) namespace Gdp.IServer.Ui.Web.Hubs { using Microsoft.AspNet.SignalR.Hubs; [HubName("iServerHub")] public class IServerHub : Hub { public void Send(string name, string message) { Clients.All.broadcastMessage(name, message); } } } And this is map.js $(function () { // Declare a proxy to reference the hub. var clientServerHub = $.connection.iServerHub; // Create a function that the hub can call to broadcast messages. clientServerHub.client.broadcastMessage = function (name, message) { $('#discussion').append('<li><strong>' + name + '</strong>:&nbsp;&nbsp;' + message + '</li>'); }; // Get the user name and store it to prepend to messages. $('#displayname').val(prompt('Enter your name:', '')); // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.start().done(function () { $('#sendmessage').click(function () { // Html encode display name and message. var encodedName = $('<div />').text($('#displayname').val()).html(); var encodedMsg = $('<div />').text($('#message').val()).html(); // Call the Send method on the hub. clientServerHub.server.send(encodedName, encodedMsg); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); }); }); The DLL's I see references for SignalR are: Microsoft.AspNet.SignalR.Core Microsoft.AspNet.SignalR.Owin Microsoft.AspNet.SignalR.SystemWeb Any ideas how to get it work? Should I make any change because the scripts are in /Script/lib folder? NOTE I'm following the instruction found here on how to set up Windsor Castle to make it work with SignalR, and again, seems that the proxy cannot be created and I'm getting the same error: Cannot read property client of undefined meaning that the proxy to the hub was not created This is how I have it in the server public class IncidentServerHub : Hub and like this in the client var clientServerHub = $.connection.incidentServerHub; Again, I can see the dynamically created file here: /GdpSoftware.Server.Web/signalr/hubs So, Why the proxy is not created? Thanks in advance!!! Guillermo.

• Bluetooth RFCOMM / SDP connection to a RS232 adapter in android

  - by ThePosey

  Hello All, I am trying to use the Bluetooth Chat sample API app that google provides to connect to a bluetooth RS232 adapter hooked up to another device. Here is the app for reference: http://developer.android.com/resources/samples/BluetoothChat/index.html And here is the spec sheet for the RS232 connector just for reference: http://serialio.com/download/Docs/BlueSnap-guide-4.77_Commands.pdf Well the problem is that when I go to connect to the device with: mmSocket.connect(); (BluetoothSocket::connect()) I always get an IOException error thrown by the connect() method. When I do a toString on the exception I get "Service discovery failed". My question is mostly what are the cases that would cause an IOException to get thrown in the connect method? I know those are in the source somewhere but I don't know exactly how the java layer that you write apps in and the C/C++ layer that contains the actual stacks interface. I know that it uses the bluez bluetooth stack which is written in C/C++ but not sure how that ties into the java layer which is what I would think is throwing the exception. Any help on pointing me to where I can try to dissect this issue would be incredible. Also just to note I am able to pair with the RS232 adapter just fine but I am never able to actually connect. Here is the logcat output for more reference: I/ActivityManager( 1018): Displayed activity com.example.android.BluetoothChat/.DeviceListActivity: 326 ms (total 326 ms) E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) D/BluetoothChat( 1729): onActivityResult -1 D/BluetoothChatService( 1729): connect to: 00:06:66:03:0C:51 D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_CONNECTING E/BluetoothChat( 1729): + ON RESUME + I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_CONNECTING I/BluetoothChatService( 1729): BEGIN mConnectThread E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 I/BluetoothChatService( 1729): CONNECTION FAIL TOSTRING: java.io.IOException: Service discovery failed D/BluetoothChatService( 1729): setState() STATE_CONNECTING - STATE_LISTEN D/BluetoothChatService( 1729): start D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_LISTEN I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID I/NotificationService( 1018): enqueueToast pkg=com.example.android.BluetoothChat callback=android.app.ITransientNotification$Stub$Proxy@446327c8 duration=0 I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID The device I'm trying to connect to is the 00:06:66:03:0C:51 which I can scan for and apparently pair with just fine. The below is merged from a similar question which was successfully resolved by the selected answer here: How can one connect to an rfcomm device other than another phone in Android? The Android API provides examples of using listenUsingRfcommWithServiceRecord() to set up a socket and createRfcommSocketToServiceRecord() to connect to that socket. I'm trying to connect to an embedded device with a BlueSMiRF Gold chip. My working Python code (using the PyBluez library), which I'd like to port to Android, is as follows: sock = bluetooth.BluetoothSocket(proto=bluetooth.RFCOMM) sock.connect((device_addr, 1)) return sock.makefile() ...so the service to connect to is simply defined as channel 1, without any SDP lookup. As the only documented mechanism I see in the Android API does SDP lookup of a UUID, I'm slightly at a loss. Using "sdptool browse" from my Linux host comes up empty, so I surmise that the chip in question simply lacks SDP support.

• Image auto resizes in PdfPCell with iTextSharp

  - by Mladen Prajdic

  Hi, i'm having a weird problem with images in iTextSharp library. I'm adding the image to the PdfPCell and for some reason it gets scaled up. How do i keep it to original size? Here's the image of the PDF at 100% and the image in its original size opened in paint.net. I though that the images would be same when printed but the difference on the pic is the same on the printed version. Having to manually scale the image with ScaleXXX to get it to right seems a bit illogical and does not give a good result. So how do I put the image in its original size inside a PdfPCell of a table without having to scale it? Here's my code: private PdfPTable CreateTestPDF() { PdfPTable table = new PdfPTable(1); table.WidthPercentage = 100; Phrase phrase = new Phrase("MY TITLE", _font24Bold); table.AddCell(phrase); PdfPTable nestedTable = new PdfPTable(5); table.WidthPercentage = 100; Phrase cellText = new Phrase("cell 1", _font9BoldBlack); nestedTable.AddCell(cellText); cellText = new Phrase("cell 2", _font9BoldBlack); nestedTable.AddCell(cellText); cellText = new Phrase("cell 3", _font9BoldBlack); nestedTable.AddCell(cellText); iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(@"d:\MyPic.jpg"); image.Alignment = iTextSharp.text.Image.ALIGN_CENTER; PdfPCell cell = new PdfPCell(image); cell.HorizontalAlignment = PdfPCell.ALIGN_MIDDLE; nestedTable.AddCell(cell); cellText = new Phrase("cell 5", _font9BoldBlack); nestedTable.AddCell(cellText); nestedTable.AddCell(""); string articleInfo = "Test Text"; cellText = new Phrase(articleInfo, _font8Black); nestedTable.AddCell(cellText); nestedTable.AddCell(""); nestedTable.AddCell(""); nestedTable.AddCell(""); table.AddCell(nestedTable); SetBorderSizeForAllCells(table, iTextSharp.text.Rectangle.NO_BORDER); return table; } static BaseColor _textColor = new BaseColor(154, 154, 154); iTextSharp.text.Font _font8 = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 8, iTextSharp.text.Font.NORMAL, _textColor); iTextSharp.text.Font _font8Black = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 8, iTextSharp.text.Font.NORMAL, BaseColor.BLACK); iTextSharp.text.Font _font9 = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 9, iTextSharp.text.Font.NORMAL, _textColor); iTextSharp.text.Font _font9BoldBlack = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 9, iTextSharp.text.Font.BOLD, BaseColor.BLACK); iTextSharp.text.Font _font10 = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 10, iTextSharp.text.Font.NORMAL, _textColor); iTextSharp.text.Font _font10Black = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 10, iTextSharp.text.Font.NORMAL, BaseColor.BLACK); iTextSharp.text.Font _font10BoldBlack = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 10, iTextSharp.text.Font.BOLD, BaseColor.BLACK); iTextSharp.text.Font _font24Bold = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 24, iTextSharp.text.Font.BOLD, _textColor);

• How to intercept raw soap request/response (data) from WCF client

  - by JohnIdol

  This question seems to be pretty close to what I am looking for - I was able to setup tracing and I am looking at the log entries for my calls to the service.

• TemplateBinding with Converter - what is wrong?

  - by MartyIX

  I'm creating a game desk. I wanted to specify field size (one field is a square) as a attached property and with this data set value of ViewPort which would draw 2x2 matrix (and tile mode would do the rest of game desk).

• Build problems when adding `__str__` method to Boost Python C++ class

  - by Rickard

  I have started to play around with boost python a bit and ran into a problem. I tried to expose a C++ class to python which posed no problems. But I can't seem to manage to implement the __str__ functionality for the class without getting build errors I don't understand. I'm using boost 1_42 prebuild by boostpro. I build the library using cmake and the vs2010 compiler. I have a very simple setup. The header-file (tutorial.h) looks like the following: #include <iostream> namespace TestBoostPython{ class TestClass { private: double m_x; public: TestClass(double x); double Get_x() const; void Set_x(double x); }; std::ostream &operator<<(std::ostream &ostr, const TestClass &ts); }; and the corresponding cpp-file looks like: #include <boost/python.hpp> #include "tutorial.h" using namespace TestBoostPython; TestClass::TestClass(double x) { m_x = x; } double TestClass::Get_x() const { return m_x; } void TestClass::Set_x(double x) { m_x = x; } std::ostream &operator<<(std::ostream &ostr, TestClass &ts) { ostr << ts.Get_x() << "\n"; return ostr; } BOOST_PYTHON_MODULE(testme) { using namespace boost::python; class_<TestClass>("TestClass", init<double>()) .add_property("x", &TestClass::Get_x, &TestClass::Set_x) .def(str(self)) ; } The CMakeLists.txt looks like the following: CMAKE_MINIMUM_REQUIRED(VERSION 2.8) project (testme) FIND_PACKAGE( Boost REQUIRED ) FIND_PACKAGE( Boost COMPONENTS python REQUIRED ) FIND_PACKAGE( PythonLibs REQUIRED ) set(Boost_USE_STATIC_LIBS OFF) set(Boost_USE_MULTITHREAD ON) INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS}) INCLUDE_DIRECTORIES ( ${PYTHON_INCLUDE_PATH} ) add_library(testme SHARED tutorial.cpp) target_link_libraries(testme ${Boost_PYTHON_LIBRARY}) target_link_libraries(testme ${PYTHON_LIBRARY} The build error I get is the following: Compiling... tutorial.cpp C:\Program Files (x86)\boost\boost_1_42\boost/python/def_visitor.hpp(31) : error C2780: 'void boost::python::api::object_operators::visit(ClassT &,const char *,const boost::python::detail::def_helper &) const' : expects 3 arguments - 1 provided with [ U=boost::python::api::object ] C:\Program Files (x86)\boost\boost_1_42\boost/python/object_core.hpp(203) : see declaration of 'boost::python::api::object_operators::visit' with [ U=boost::python::api::object ] C:\Program Files (x86)\boost\boost_1_42\boost/python/def_visitor.hpp(67) : see reference to function template instantiation 'void boost::python::def_visitor_access::visit,classT>(const V &,classT &)' being compiled with [ DerivedVisitor=boost::python::api::object, classT=boost::python::class_, V=boost::python::def_visitor ] C:\Program Files (x86)\boost\boost_1_42\boost/python/class.hpp(225) : see reference to function template instantiation 'void boost::python::def_visitor::visit>(classT &) const' being compiled with [ DerivedVisitor=boost::python::api::object, W=TestBoostPython::TestClass, classT=boost::python::class_ ] .\tutorial.cpp(29) : see reference to function template instantiation 'boost::python::class_ &boost::python::class_::def(const boost::python::def_visitor &)' being compiled with [ W=TestBoostPython::TestClass, U=boost::python::api::object, DerivedVisitor=boost::python::api::object ] Does anyone have any idea on what went wrrong? If I remove the .def(str(self)) part from the wrapper code, everything compiles fine and the class is usable from python. I'd be very greatful for assistance. Thank you, Rickard

• I created a custom (WPF) DataGridBoundColumn and get unexpected behaviour, what am I missing?

  - by aspic

  Hi, I am using a DataGrid (from Microsoft.Windows.Controls.DataGrid) to display items on and on this DataGrid I use a custom Column which extends DataGridBoundColumn. I have bound an ObservableCollection to the ItemSource of the DataGrid. Conversation is one of my own custom datatypes which a (among other things) has a boolean called active. I bound this boolean to the DataGrid as follows: DataGridActiveImageColumn test = new DataGridActiveImageColumn(); test.Header = "Active"; Binding binding1 = new Binding("Active"); test.Binding = binding1; ConversationsDataGrid.Columns.Add(test); My custom DataGridBoundColumn DataGridActiveImageColumn overrides the GenerateElement method to let it return an Image depending on whether the conversation it is called for is active or not. The code for this is: namespace Microsoft.Windows.Controls { class DataGridActiveImageColumn : DataGridBoundColumn { protected override FrameworkElement GenerateElement(DataGridCell cell, object dataItem) { // Create Image Element Image myImage = new Image(); myImage.Width = 10; bool active=false; if (dataItem is Conversation) { Conversation c = (Conversation)dataItem; active = c.Active; } BitmapImage myBitmapImage = new BitmapImage(); // BitmapImage.UriSource must be in a BeginInit/EndInit block myBitmapImage.BeginInit(); if (active) { myBitmapImage.UriSource = new Uri(@"images\active.png", UriKind.Relative); } else { myBitmapImage.UriSource = new Uri(@"images\inactive.png", UriKind.Relative); } // To save significant application memory, set the DecodePixelWidth or // DecodePixelHeight of the BitmapImage value of the image source to the desired // height or width of the rendered image. If you don't do this, the application will // cache the image as though it were rendered as its normal size rather then just // the size that is displayed. // Note: In order to preserve aspect ratio, set DecodePixelWidth // or DecodePixelHeight but not both. myBitmapImage.DecodePixelWidth = 10; myBitmapImage.EndInit(); myImage.Source = myBitmapImage; return myImage; } protected override FrameworkElement GenerateEditingElement(DataGridCell cell, object dataItem) { throw new NotImplementedException(); } } } All this works as expected, and when during the running of the program the active boolean of conversations changes, this is automatically updated in the DataGrid. However: When there are more entries on the DataGrid then fit at any one time (and vertical scrollbars are added) the behavior with respect to the column for all the conversations is strange. The conversations that are initially loaded are correct, but when I use the scrollbar of the DataGrid conversations that enter the view seems to have a random status (although more inactive than active ones, which corresponds to the actual ratio). When I scroll back up, the active images of the Conversations initially shown (before scrolling) are not correct anymore as well. When I replace my custom DataGridBoundColumn class with (for instance) DataGridCheckBoxColumn it works as intended so my extension of the DataGridBoundColumn class must be incomplete. Personally I think it has something to do with the following: From the MSDN page on the GenerateElement method (http://msdn.microsoft.com/en-us/library/system.windows.controls.datagridcolumn.generateelement%28VS.95%29.aspx): Return Value Type: System.Windows. FrameworkElement A new, read-only element that is bound to the column's Binding property value. I do return a new element (the image) but it is not bound to anything. I am not quite sure what I should do. Should I bind the Image to something? To what exactly? And why? (I have been experimenting, but was unsuccessful thus far, hence this post) Thanks in advance.

  I am creating a simple application to get familiar with SlimDX library. I found some code written in MDX and I'm trying to convert it to run on SlimDX. I am having some problems with the light because everything is being shown as black. The code is: public partial class DirectTest : Form { private Device device= null; private float angle = 0.0f; Light light = new Light(); public DirectTest() { InitializeComponent(); this.Size = new Size(800, 600); this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.Opaque, true); } /// <summary> /// We will initialize our graphics device here /// </summary> public void InitializeGraphics() { PresentParameters pres_params = new PresentParameters() { Windowed = true, SwapEffect = SwapEffect.Discard }; device = new Device(new Direct3D(), 0, DeviceType.Hardware, this.Handle, CreateFlags.SoftwareVertexProcessing, pres_params); } private void SetupCamera() { device.SetRenderState(RenderState.CullMode, Cull.None); device.SetTransform(TransformState.World, Matrix.RotationAxis(new Vector3(angle / ((float)Math.PI * 2.0f), angle / ((float)Math.PI * 4.0f), angle / ((float)Math.PI * 6.0f)), angle / (float)Math.PI)); angle += 0.1f; device.SetTransform(TransformState.Projection, Matrix.PerspectiveFovLH((float)Math.PI / 4, this.Width / this.Height, 1.0f, 100.0f)); device.SetTransform(TransformState.View, Matrix.LookAtLH(new Vector3(0, 0, 5.0f), new Vector3(), new Vector3(0, 1, 0))); device.SetRenderState(RenderState.Lighting, false); } protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { device.Clear(ClearFlags.Target | ClearFlags.ZBuffer, Color.CornflowerBlue, 1.0f, 0); SetupCamera(); CustomVertex.PositionColored[] verts = new CustomVertex.PositionColored[3]; verts[0].Position = new Vector3(0.0f, 1.0f, 1.0f); verts[0].Normal = new Vector3(0.0f, 0.0f, -1.0f); verts[0].Color = System.Drawing.Color.White.ToArgb(); verts[1].Position = new Vector3(-1.0f, -1.0f, 1.0f); verts[1].Normal = new Vector3(0.0f, 0.0f, -1.0f); verts[1].Color = System.Drawing.Color.White.ToArgb(); verts[2].Position = new Vector3(1.0f, -1.0f, 1.0f); verts[2].Normal = new Vector3(0.0f, 0.0f, -1.0f); verts[2].Color = System.Drawing.Color.White.ToArgb(); light.Type = LightType.Point; light.Position = new Vector3(); light.Diffuse = System.Drawing.Color.White; light.Attenuation0 = 0.2f; light.Range = 10000.0f; device.SetLight(0, light); device.EnableLight(0, true); device.BeginScene(); device.VertexFormat = CustomVertex.PositionColored.format; device.DrawUserPrimitives<CustomVertex.PositionColored>(PrimitiveType.TriangleList, 1, verts); device.EndScene(); device.Present(); this.Invalidate(); } } } The Vertex Format that I am using is the following [StructLayout(LayoutKind.Sequential)] public struct PositionNormalColored { public Vector3 Position; public int Color; public Vector3 Normal; public static readonly VertexFormat format = VertexFormat.Diffuse | VertexFormat.Position | VertexFormat.Normal; } Any suggestions on what the problem might be? Thanks in Advance

• WCF app Deployed on Win7 Machine and get connection refused error

  - by Belliez

  I have created a Sync Framework application based on the following sample from microsoft and deployed it to a new Windows 7 machine for testing. The app runs ok but when I attempt to communicate I get the following error: Could not connect to http://localhost:8000/RelationalSyncContract/SqlSyncService/. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8000. I am wondering if there is something I am missing. This is my first experience using WCF and followed microsoft sample code. I have disabled the firewall and opened port 8000 for both TCP and UDP. Not sure what to look at next. Below is my App.config file if this helps: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="true"/> <httpRuntime maxRequestLength="32768" /> </system.web> <!-- When deploying the service library project, the content of the config file must be added to the host's app.config file.

• Own DataFormWebPart: Unable to display this Web Part.

  - by user307852

  Hi, What I want is to display a paginable list from my custom data source. All came from the fact that I needed some logical relationships between seach scopes and some dates. I considered ContentQueryWebpart, but CAML is too complicated as I have plenty of different conditions, CoreResults webpart is too limited as it uses KeyWordQuery so I inherited from DataFormWebPart to display my own custom search results from my own custom xml source. Thats the best way i am aware of... I knew I needed some configuration to write in my pageLayout like MyWebParts:MyCustomWebPart etc so I went to Designer, put DataFormWebPart on a page, linked it to list of pages, and set multiple item view and that gave me some configuration.. Firstly i checked if DataFormWebPart works when put on pageLayout and it sucessfully displayed my pages list in pages library. But that was not what I wanted, i needed to set my own XML data source... I then changed the configuration of WebPartPages:DataFormWebPart to match mine and detach from any listName or listId and I change the XSL tag to much simplier to display all results and now I am getting: Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator. and there is no way to know what is wrong:/ The webpart public class MyCustomWebPart : DataFormWebPart{ public override void DataBind() { ......

• OpenGL/SharpGL - Points only on -near surface of Ortho projection?

  - by FTLPhysicsGuy

  When you create points using three dimensions for each point and you use an Ortho projection to view the points, would there be a reason that only the points on the -near surface would appear? For example, if you use (the SharpGL method) gl.Ortho(0, width, height, 0, -10, 10), only the points at z=10 (because the near surface is at -10) actually show up. I'm currently using SharpGL - but I'm hoping the issue I'm having isn't with that particular implementation/library. EDIT: I'm adding the code below that demonstrates the issue. Note that this example requires SharpGL and is in fact a modification of a WPF sample project that comes with the current SharpGL source code (the original sample project is called TwoDSample). The project requires a MainWindow.xaml and a MainWindow.xaml.cs. Here's the xaml: <Window x:Class="TwoDSample.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" xmlns:my="clr-namespace:SharpGL.WPF;assembly=SharpGL.WPF"> <Grid> <my:OpenGLControl Name="openGLControl1" OpenGLDraw="openGLControl1_OpenGLDraw" OpenGLInitialized="openGLControl1_OpenGLInitialized" Resized="openGLControl1_Resized"/> </Grid> </Window> Here is the code behind: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using SharpGL.Enumerations; namespace TwoDSample { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } // NOTE: I use this to restrict the openGLControl1_OpenGLDraw method to // drawing only once after m_drawCount is set to zero; int m_drawCount = 0; private void openGLControl1_OpenGLDraw(object sender, SharpGL.SceneGraph.OpenGLEventArgs args) { // NOTE: Only draw once after m_drawCount is set to zero if (m_drawCount < 1) { // Get the OpenGL instance. var gl = args.OpenGL; gl.Color(1f, 0f, 0f); gl.PointSize(2.0f); // Draw 10000 random points. gl.Begin(BeginMode.Points); Random random = new Random(); for (int i = 0; i < 10000; i++) { double x = 10 + 400 * random.NextDouble(); double y = 10 + 400 * random.NextDouble(); double z = (double)random.Next(-10, 0); // Color the point according to z value gl.Color(0f, 0f, 1f); // default to blue if (z == -10) gl.Color(1f, 0f, 0f); // Red for z = -10 else if (z == -1) gl.Color(0f, 1f, 0f); // Green for z = -1 gl.Vertex(x, y, z); } gl.End(); m_drawCount++; } } private void openGLControl1_OpenGLInitialized(object sender, SharpGL.SceneGraph.OpenGLEventArgs args) { } private void openGLControl1_Resized(object sender, SharpGL.SceneGraph.OpenGLEventArgs args) { // NOTE: force the draw routine to happen again when resize occurs m_drawCount = 0; // Get the OpenGL instance. var gl = args.OpenGL; // Create an orthographic projection. gl.MatrixMode(MatrixMode.Projection); gl.LoadIdentity(); // NOTE: Basically no matter what I do, the only points I see are those at // the "near" surface (with z = -zNear)--in this case, I only see green points gl.Ortho(0, openGLControl1.ActualWidth, openGLControl1.ActualHeight, 0, 1, 10); // Back to the modelview. gl.MatrixMode(MatrixMode.Modelview); } } }
