• ApiChange Is Released!

  - by Alois Kraus

  I have been working on little tool to simplify my life and perhaps yours as developer as well. It is basically a command line tool that allows you to execute queries on your compiled .NET code base. The main purpose is to find out how big the impact of an api change would be if you changed this or that.  Now you can do high level operations like Diff public types for breaking changes. Who uses a method? Who uses a type? Who uses implements an interface? Who references me? What format has the binary  (32/64, Managed C++, Pure IL, Unmanaged)? Search for all event subscribers and unsubscribers. A unique feature is to check for event subscription imbalances. Forgotten event subscriptions are the 90% cause of managed memory leaks. It is done at a per class level. If one class does subscribe to one event more often than it does unsubscribe it is treated as possible event subscription imbalance. Another unique ability is to search for users of string literals which allows you to track users of a string constant which is not possible otherwise. For incremental builds the ShowRebuildTargets command can be used to identify the dependant targets that need a rebuild after you did compile one assembly. It has some heuristics in place to determine the impact of breaking changes and finds out which targets need to be recompiled as well. It has a ton of other features and a an API to access these things programmatically so you can build upon these simple queries create even better tools. Perhaps we get a Visual Studio plug in? You can download it from CodePlex here. It works via XCopy deployment. Simply let it run and check the command line help out. The best feature in my opinion is that the output of nearly all commands can be piped to Excel for further analysis. Since it does read also the pdbs it can show you the source file name and line number as well for all matches. The following picture shows the output of a –WhousesType query. The following command checks where type from BaseLibraryV1.dll are used inside DependantLibV1.dll. All matches are printed out with the reason and matching item along with file and line number. There is even a hyper link to the match which will open Visual Studio. ApiChange -whousestype "*" BaseLibraryV1.dll -in DependantLibV1.dll –excel The "*” is the actual query which means all types. The syntax is the same like in C# just that placeholders are allowed ;-). More info's can be found at the Codeplex Documentation.     The tool was developed in a TDD style manner which means that it is heavily tested and already used by a quite large user base inside the company I do work for. Luckily for you I got the permission to make it public so you take advantage of it. It is fully instrumented with tracing. If you find bugs simply add the –trace command line switch to find out what is failing and send me the output. How is it done? Your first guess might be that it uses reflection. Wrong. It is based on Mono Cecil a free IL parser with a fantastic API to access all internals of a managed assembly. The speed is awesome and to make it even faster I did make the tool heavily multi threaded. The query above did execute in 1.8s with the Excel output. On a rather slow machine I can analyze over 1500 assemblies in less than 40s with a very low memory consumption. The true power of Mono Cecil is that I can load an assembly like any other data file. I have no problems unloading a file but if I would have used reflection I would need to unload a whole AppDomain just to get rid of one assembly in my memory. Just to give you a glimpse how ApiChange.Api.dll can be used I show you one of the unit tests:           public void Can_Find_GenericMethodInvocations_With_Type_Parameters()         { // 1. Create an aggregator to collect our matches             UsageQueryAggregator agg = new UsageQueryAggregator();   // 2. This is the type we want to search for. Load it via the type query             var decimalType = TypeQuery.GetTypeByName(TestConstants.MscorlibAssembly, "System.Decimal");   // 3. register the type query which searches for uses of the Decimal type             new WhoUsesType(agg, decimalType);   // 4. Search for all users of the Decimal type in the DependandLibV1Assembly             agg.Analyze(TestConstants.DependandLibV1Assembly);   // Extract matches and assert             Assert.AreEqual(2, agg.MethodMatches.Count, "Method match count");             Assert.AreEqual("UseGenericMethod", agg.MethodMatches[0].Match.Name);             Assert.AreEqual("UseGenericMethod", agg.MethodMatches[1].Match.Name);         } Many thanks go from here to Jb Evian for the creation of Mono.Cecil. Without this fantastic piece of code it would have been much much harder. There are other options around like the Common Compiler Infrastructure  Metadata Api which should do the same thing but it was not a real option since the Microsoft reader did fail on even simple assemblies (at least in September 2009 this was the case). Besides this I found the CCI Apis much harder to use. The only real competitor was Reflector which does support many things but does not let me access his cool high level analyze commands. So I decided to dig into the IL specs and as a result you can query your compiled binaries from the command line or programmatically. The best thing is you try it out for yourself and give me some feedback what you miss. If you want to contribute or have a cool idea what should be added drop me a mail at A Kraus1@___No [email protected]. There is much more inside the tool I did not talk about it (yet).

• MapRedux - PowerShell and Big Data

  - by Dittenhafer Solutions

  MapRedux – #PowerShell and #Big Data Have you been hearing about “big data”, “map reduce” and other large scale computing terms over the past couple of years and been curious to dig into more detail? Have you read some of the Apache Hadoop online documentation and unfortunately concluded that it wasn't feasible to setup a “test” hadoop environment on your machine? More recently, I have read about some of Microsoft’s work to enable Hadoop on the Azure cloud. Being a "Microsoft"-leaning technologist, I am more inclinded to be successful with experimentation when on the Windows platform. Of course, it is not that I am "religious" about one set of technologies other another, but rather more experienced. Anyway, within the past couple of weeks I have been thinking about PowerShell a bit more as the 2012 PowerShell Scripting Games approach and it occured to me that PowerShell's support for Windows Remote Management (WinRM), and some other inherent features of PowerShell might lend themselves particularly well to a simple implementation of the MapReduce framework. I fired up my PowerShell ISE and started writing just to see where it would take me. Quite simply, the ScriptBlock feature combined with the ability of Invoke-Command to create remote jobs on networked servers provides much of the plumbing of a distributed computing environment. There are some limiting factors of course. Microsoft provided some default settings which prevent PowerShell from taking over a network without administrative approval first. But even with just one adjustment, a given Windows-based machine can become a node in a MapReduce-style distributed computing environment. Ok, so enough introduction. Let's talk about the code. First, any machine that will participate as a remote "node" will need WinRM enabled for remote access, as shown below. This is not exactly practical for hundreds of intended nodes, but for one (or five) machines in a test environment it does just fine. C:> winrm quickconfig WinRM is not set up to receive requests on this machine. The following changes must be made: Set the WinRM service type to auto start. Start the WinRM service. Make these changes [y/n]? y Alternatively, you could take the approach described in the Remotely enable PSRemoting post from the TechNet forum and use PowerShell to create remote scheduled tasks that will call Enable-PSRemoting on each intended node. Invoke-MapRedux Moving on, now that you have one or more remote "nodes" enabled, you can consider the actual Map and Reduce algorithms. Consider the following snippet: $MyMrResults = Invoke-MapRedux -MapReduceItem $Mr -ComputerName $MyNodes -DataSet $dataset -Verbose Invoke-MapRedux takes an instance of a MapReduceItem which references the Map and Reduce scriptblocks, an array of computer names which are the remote nodes, and the initial data set to be processed. As simple as that, you can start working with concepts of big data and the MapReduce paradigm. Now, how did we get there? I have published the initial version of my PsMapRedux PowerShell Module on GitHub. The PsMapRedux module provides the Invoke-MapRedux function described above. Feel free to browse the underlying code and even contribute to the project! In a later post, I plan to show some of the inner workings of the module, but for now let's move on to how the Map and Reduce functions are defined. Map Both the Map and Reduce functions need to follow a prescribed prototype. The prototype for a Map function in the MapRedux module is as follows. A simple scriptblock that takes one PsObject parameter and returns a hashtable. It is important to note that the PsObject $dataset parameter is a MapRedux custom object that has a "Data" property which offers an array of data to be processed by the Map function. $aMap = { Param ( [PsObject] $dataset ) # Indicate the job is running on the remote node. Write-Host ($env:computername + "::Map"); # The hashtable to return $list = @{}; # ... Perform the mapping work and prepare the $list hashtable result with your custom PSObject... # ... The $dataset has a single 'Data' property which contains an array of data rows # which is a subset of the originally submitted data set. # Return the hashtable (Key, PSObject) Write-Output $list; } Reduce Likewise, with the Reduce function a simple prototype must be followed which takes a $key and a result $dataset from the MapRedux's partitioning function (which joins the Map results by key). Again, the $dataset is a MapRedux custom object that has a "Data" property as described in the Map section. $aReduce = { Param ( [object] $key, [PSObject] $dataset ) Write-Host ($env:computername + "::Reduce - Count: " + $dataset.Data.Count) # The hashtable to return $redux = @{}; # Return Write-Output $redux; } All Together Now When everything is put together in a short example script, you implement your Map and Reduce functions, query for some starting data, build the MapReduxItem via New-MapReduxItem and call Invoke-MapRedux to get the process started: # Import the MapRedux and SQL Server providers Import-Module "MapRedux" Import-Module “sqlps” -DisableNameChecking # Query the database for a dataset Set-Location SQLSERVER:\sql\dbserver1\default\databases\myDb $query = "SELECT MyKey, Date, Value1 FROM BigData ORDER BY MyKey"; Write-Host "Query: $query" $dataset = Invoke-SqlCmd -query $query # Build the Map function $MyMap = { Param ( [PsObject] $dataset ) Write-Host ($env:computername + "::Map"); $list = @{}; foreach($row in $dataset.Data) { # Write-Host ("Key: " + $row.MyKey.ToString()); if($list.ContainsKey($row.MyKey) -eq $true) { $s = $list.Item($row.MyKey); $s.Sum += $row.Value1; $s.Count++; } else { $s = New-Object PSObject; $s | Add-Member -Type NoteProperty -Name MyKey -Value $row.MyKey; $s | Add-Member -type NoteProperty -Name Sum -Value $row.Value1; $list.Add($row.MyKey, $s); } } Write-Output $list; } $MyReduce = { Param ( [object] $key, [PSObject] $dataset ) Write-Host ($env:computername + "::Reduce - Count: " + $dataset.Data.Count) $redux = @{}; $count = 0; foreach($s in $dataset.Data) { $sum += $s.Sum; $count += 1; } # Reduce $redux.Add($s.MyKey, $sum / $count); # Return Write-Output $redux; } # Create the item data $Mr = New-MapReduxItem "My Test MapReduce Job" $MyMap $MyReduce # Array of processing nodes... $MyNodes = ("node1", "node2", "node3", "node4", "localhost") # Run the Map Reduce routine... $MyMrResults = Invoke-MapRedux -MapReduceItem $Mr -ComputerName $MyNodes -DataSet $dataset -Verbose # Show the results Set-Location C:\ $MyMrResults | Out-GridView Conclusion I hope you have seen through this article that PowerShell has a significant infrastructure available for distributed computing. While it does take some code to expose a MapReduce-style framework, much of the work is already done and PowerShell could prove to be the the easiest platform to develop and run big data jobs in your corporate data center, potentially in the Azure cloud, or certainly as an academic excerise at home or school. Follow me on Twitter to stay up to date on the continuing progress of my Powershell MapRedux module, and thanks for reading! Daniel

• Creating a Document Library with Content Type in code

  - by David Jacobus

  Originally posted on: http://geekswithblogs.net/djacobus/archive/2013/10/15/154360.aspxIn the past, I have shown how to create a list content type and add the content type to a list in code.  As a Developer, many of the artifacts which we create are widgets which have a List or Document Library as the back end.   We need to be able to create our applications (Web Part, etc.) without having the user involved except to enter the list item data.  Today, I will show you how to do the same with a document library.    A summary of what we will do is as follows:   1.   Create an Empty SharePoint Project in Visual Studio 2.   Add a Code Folder in the solution and Drag and Drop Utilities and Extensions Libraries to the solution 3.   Create a new Feature and add and event receiver  all the code will be in the event receiver 4.   Add the fields which will extend the built-in Document content type 5.   If the Content Type does not exist, Create it 6.   If the Document Library does not exist, Create it with the new Content Type inherited from the Document Content Type 7.   Delete the Document Content Type from the Library (as we have a new one which inherited from it) 8.   Add the fields which we want to be visible from the fields added to the new Content Type   Here we go:   Create an Empty SharePoint Project in Visual Studio      Add a Code Folder in the solution and Drag and Drop Utilities and Extensions Libraries to the solution       The Utilities and Extensions Library will be part of this project which I will provide a download link at the end of this post.  Drag and drop them into your project.  If Dragged and Dropped from windows explorer you will need to show all files and then include them in your project.  Change the Namespace to agree with your project.   Create a new Feature and add and event receiver  all the code will be in the event receiver.  Here We added a new Feature called “CreateDocLib”  and then right click to add an Event Receiver All of our code will be in this Event Receiver.  For this Demo I will only be using the Feature Activated Event.      From this point on we will be looking at code!    We are adding two constants for use columGroup (How we want SharePoint to Group them, usually Company Name) and ctName(ContentType Name)  using System; using System.Runtime.InteropServices; using System.Security.Permissions; using Microsoft.SharePoint; namespace CreateDocLib.Features.CreateDocLib { /// <summary> /// This class handles events raised during feature activation, deactivation, installation, uninstallation, and upgrade. /// </summary> /// <remarks> /// The GUID attached to this class may be used during packaging and should not be modified. /// </remarks> [Guid("56e6897c-97c4-41ac-bc5b-5cd2c04f2dd1")] public class CreateDocLibEventReceiver : SPFeatureReceiver { const string columnGroup = "DJ"; const string ctName = "DJDocLib"; } }     Here we are creating the Feature Activated event.   Adding the new fields (Site Columns) ,  Testing if the Content Type Exists, if not adding it.  Testing if the document Library exists, if not adding it.   #region DocLib public override void FeatureActivated(SPFeatureReceiverProperties properties) { using (SPWeb spWeb = properties.GetWeb() as SPWeb) { //add the fields addFields(spWeb); //add content type SPContentType testCT = spWeb.ContentTypes[ctName]; // we will not create the content type if it exists if (testCT == null) { //the content type does not exist add it addContentType(spWeb, ctName); } if ((spWeb.Lists.TryGetList("MyDocuments") == null)) { //create the list if it dosen't to exist CreateDocLib(spWeb); } } } #endregion The addFields method uses the utilities library to add site columns to the site. We can add as many fields within this method as we like. Here we are adding one for demonstration purposes. Icon as a Url type.  public void addFields(SPWeb spWeb) { Utilities.addField(spWeb, "Icon", SPFieldType.URL, false, columnGroup); }The addContentType method add the new Content Type to the site Content Types. We have already checked to see that it does not exist. In addition, here is where we add the linkages from our site columns previously created to our new Content Type   private static void addContentType(SPWeb spWeb, string name) { SPContentType myContentType = new SPContentType(spWeb.ContentTypes["Document"], spWeb.ContentTypes, name) { Group = columnGroup }; spWeb.ContentTypes.Add(myContentType); addContentTypeLinkages(spWeb, myContentType); myContentType.Update(); } Here we are adding just one linkage as we only have one additional field in our Content Type public static void addContentTypeLinkages(SPWeb spWeb, SPContentType ct) { Utilities.addContentTypeLink(spWeb, "Icon", ct); } Next we add the logic to create our new Document Library, which we have already checked to see if it exists.  We create the document library and turn on content types.  Add the new content type and then delete the old “Document” content types.   private void CreateDocLib(SPWeb web) { using (var site = new SPSite(web.Url)) { var web1 = site.RootWeb; var listId = web1.Lists.Add("MyDocuments", string.Empty, SPListTemplateType.DocumentLibrary); var lib = web1.Lists[listId] as SPDocumentLibrary; lib.ContentTypesEnabled = true; var docType = web.ContentTypes[ctName]; lib.ContentTypes.Add(docType); lib.ContentTypes.Delete(lib.ContentTypes["Document"].Id); lib.Update(); AddLibrarySettings(web1, lib); } }  Finally, we set some document library settings on our new document library with the AddLibrarySettings method. We then ensure that the new site column is visible when viewed in the browser.  private void AddLibrarySettings(SPWeb web, SPDocumentLibrary lib) { lib.OnQuickLaunch = true; lib.ForceCheckout = true; lib.EnableVersioning = true; lib.MajorVersionLimit = 5; lib.EnableMinorVersions = true; lib.MajorWithMinorVersionsLimit = 5; lib.Update(); var view = lib.DefaultView; view.ViewFields.Add("Icon"); view.Update(); } Okay, what's cool here: In a few lines of code, we have created site columns, A content Type, a document library. As a developer, I use this functionality all the time. For instance, I could now just add a web part to this same solutionwhich uses this document Library. I love SharePoint! Here is the complete solution: Create Document Library Code

• Looking into the JQuery Overlays 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 Overlays 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.I will be writing more posts regarding the most commonly used JQuery Plugins. With the JQuery Overlays Plugin we can provide the user (overlay) with more information about an image when the user hovers over the image. I have been using extensively this plugin in my websites. 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) <html lang="en"> <head>    <link rel="stylesheet" href="ImageOverlay.css" type="text/css" media="screen" />    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>    <script type="text/javascript" src="jquery.ImageOverlay.min.js"></script>         <script type="text/javascript">        $(function () {            $("#Liverpool").ImageOverlay();        });    </script>   </head><body>    <ul id="Liverpool" class="image-overlay">        <li>            <a href="www.liverpoolfc.com">                <img alt="Liverpool" src="championsofeurope.jpg" />                <div class="caption">                    <h3>Liverpool Football club</h3>                    <p>The greatest club in the world</p>                </div>            </a>        </li>    </ul></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 Overlays Plugin. Then I add 1 image in the element with "id=Liverpool". There is a caption class as well, where I place the text I want to show when the mouse hovers over the image. The caption class and the Liverpool id element are styled in the ImageOverlay.css file that can also be downloaded with the plugin.You can style the various elements of the html markup in the .css file. The Javascript code that makes it all happen follows.   <script type="text/javascript">        $(function () {            $("#Liverpool").ImageOverlay();        });    </script>        I am just calling the ImageOverlay function for the Liverpool ID element.The contents of ImageOverlay.css file follow .image-overlay { list-style: none; text-align: left; }.image-overlay li { display: inline; }.image-overlay a:link, .image-overlay a:visited, .image-overlay a:hover, .image-overlay a:active { text-decoration: none; }.image-overlay a:link img, .image-overlay a:visited img, .image-overlay a:hover img, .image-overlay a:active img { border: none; }.image-overlay a{    margin: 9px;    float: left;    background: #fff;    border: solid 2px;    overflow: hidden;    position: relative;}.image-overlay img{    position: absolute;    top: 0;    left: 0;    border: 0;}.image-overlay .caption{    float: left;    position: absolute;    background-color: #000;    width: 100%;    cursor: pointer;    /* The way to change overlay opacity is the follow properties. Opacity is a tricky issue due to        longtime IE abuse of it, so opacity is not offically supported - use at your own risk.         To play it safe, disable overlay opacity in IE. */    /* For Firefox/Opera/Safari/Chrome */    opacity: .8;    /* For IE 5-7 */    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=80);    /* For IE 8 */    -MS-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=80)";}.image-overlay .caption h1, .image-overlay .caption h2, .image-overlay .caption h3,.image-overlay .caption h4, .image-overlay .caption h5, .image-overlay .caption h6{    margin: 10px 0 10px 2px;    font-size: 26px;    font-weight: bold;    padding: 0 0 0 5px;    color:#92171a;}.image-overlay p{    text-indent: 0;    margin: 10px;    font-size: 1.2em;} It couldn't be any simpler than that. 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.Have a look at the picture below. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

• Advice for a distracted, unhappy, recently graduated programmer? [closed]

  - by Re-Invent

  I graduated 4 months ago. I had offers from a few good places to work at. At the same time I wanted to stick to building a small software business of my own, still have some ideas with good potential, some half done projects frozen in my github. But due to social pressures, I chose a job, the pay is great, but I am half-passionate about it. A small team of smart folks building useful product, working out contracts across the world. I've started finding it extremely boring. Boring to the extent that I skip 2-3 days a week together not doing work. Neither do I spend that time progressing any of my own projects. Yes, I feel stupid at the way I'm wasting time, but I don't understand exactly why is it happening. It's as if all the excitement has been drained. What can I do about it? Long version: School - I was in third standard. Only students, 6th grade had access to computer labs. I once peeked into the lab from the little door opening. No hard-disks, MS DOS on 5 1/2 inch floppies. I asked a senior student to play some sound in BASIC. He used PLAY to compose a tune. Boy! I was so excited, I was jumping from within. Back home, asked my brother to teach me some programming. We bought a book "MODERN All About GW-BASIC for Schools & Colleges". The book had everything, right from printing, to taking input, file i/o, game programming, machine level support, etc. I was in 6th standard, wrote my first game - a wheel of fortune, rotated the wheel by manipulating 16 color palette's definition. Got internet soon, got hooked to QuickBasic programming community. Made some more games "007 in Danger", "Car Crush 2" for submission to allbasiccode archives. I was extremely excited about all this. My interests now swayed into "hacking" (computer security). Taught myself some perl, found it annoying, learnt PHP and a bit of SQL. Also taught myself Visual Basic one of the winters and wrote a pacman clone with Direct X. By the time I was in 10th standard, I created some evil tools using visual basic, php and mysql and eventually landed myself into an unpaid side-job at a government facility, building evil tools for them. It was a dream come true for crackers of that time. And so was I, still very excited. Things changed soon, last two years of school were not so great as I was balancing preps for college, work at govt. and studies for school at same time. College - College was opposite of all I had wished it to be. I imagined it to be a place where I'd spend my 4 years building something awesome. It was rather an epitome of rote learning, attendance, rules, busy schedules, ban on personal laptops, hardly any hackers surrounding you and shit like that. We had to take permissions to even introduce some cultural/creative activities in our annual schedule. The labs won't be open on weekends because the lab employees had to have their leaves. Yes, a horrible place for someone like me. I still managed to pull out a project with a friend over 2 months. Showed it to people high in the academia hierarchy. They were immensely impressed, we proposed to allow personal computers for students. They made up half-assed reasons and didn't agree. We felt frustrated. And so on, I still managed to teach myself new languages, do new projects of my own, do an intern at the same govt. facility, start a small business for sometime, give a talk at a conference I'm passionate about, win game-dev and hacking contest at most respected colleges, solve good deal of programming contest problems, etc. At the same time I was not content with all these restrictions, great emphasis on rote learning, and sheer wastage of time due to college. I never felt I was overdoing, but now I feel I burnt myself out. During my last days at college, I did an intern at a bigco. While I spent my time building prototypes for certain LBS, the other interns around me, even a good friend, was just skipping time. I thought maybe, in a few weeks he would put in some serious efforts at work assigned to him, but all he did was to find creative ways to skip work, hide his face from manager, engage people in talks if they try to question his progress, etc. I tried a few time to get him on track, but it seems all he wanted was to "not to work hard at all and still reap the fruits". I don't know how others take such people, but I find their vicinity very very poisonous to one's own motivation and productivity. Over that, the place where I come from, HRs don't give much value to what have you done past 4 years. So towards the end of out intern, we all were offered work at the bigco, but the slacker, even after not writing more than 200 lines of code was made a much better offer. I felt enraged instantly - "Is this how the corp world treats someone who does fruitful, if not extra-ordinary work form them for past 6 months?". Yes, I did try to negotiate and debate. The bigcos seem blind due to departmentalization of responsibilities and many layers of management. I decided not to be in touch with any characters of that depressing play. Probably the busy time I had at college, ignoring friends, ignoring fun and squeezing every bit of free time for myself is also responsible. Probably this is what has drained all my willingness to work for anyone. I find my day job boring, at the same time I with to maintain it for financial reasons. I feel a bit burnt out, unsatisfied and at the same time an urge to quit working for someone else and start finishing my frozen side-projects (which may be profitable). Though I haven't got much to support myself with food, office, internet bills, etc in savings. I still have my day job, but I don't find it very interesting, even though the pay is higher than the slacker, I don't find money to be a great motivator here. I keep comparing myself to my past version. I wonder how to get rid of this and reboot myself back to the way I was in school days - excited about it, tinkering, building, learning new things daily, and NOT BORED?

• How to Control Screen Layouts in LightSwitch

  - by ChrisD

  Visual Studio LightSwitch has a bunch of screen templates that you can use to quickly generate screens. They give you good starting points that you can customize further. When you add a new screen to your project you see a set of screen templates that you can choose from. These templates lay out all the related data you choose to put on a screen automatically for you. And don’t under estimate them; they do a great job of laying out controls in a smart way. For instance, a tab control will be used when you select more than one related set of data to display on a screen. However, you’re not limited to taking the layout as is. In fact, the screen designer is pretty flexible and allows you to create stacks of controls in a variety of configurations. You just need to visualize your screen as a series of containers that you can lay out in rows and columns. You then place controls or stacks of controls into these areas to align the screen exactly how you want. If you’re new in Visual Studio LightSwitch, you can see this tutorial. OK, Let’s start with a simple example. I have already designed my data entities for a simple order tracking system similar to the Northwind database. I also have added a Search Data  Screen to search my Products already. Now I will add a new Details Screen for my Products and make it the default screen via the “Add New Screen” dialog: The screen designer picks a simple layout for me based on the single entity I chose, in this case Product. Hit F5 to run the application, select a Product on the search screen to open the Product Details Screen. Notice that it’s pretty simple because my entity is simple. Click the “Customize” button in the top right of the screen so we can start tweaking it. The left side of the screen shows the containership of controls and data bindings (called the content tree) and the right side shows the live preview with data. Notice that we have a simple layout of two rows but only one row is populated (with a vertical stack of controls in this case). The bottom row is empty. You can envision the screen like this: Each container will display a group of data that you select. For instance in the above screen, the top row is set to a vertical stack control and the group of data to display is coming from Product. So when laying out screens you need to think in terms of containers of controls bound to groups of data. To change the data to which a container is bound, select the data item next to the container: You can select the “New Group” item in order to create more containers (or controls) within the current container. For instance to totally control the layout, select the Product in the top row and hit the delete key. This will delete the vertical stack and therefore all the controls on the screen. The content tree will still have two rows, but the rows are now both empty. If you want a layout of four containers (two rows and two columns) then select “New Group” for the data item and then change the vertical stack control to “Two Columns” for both of the rows as shown here: You can keep going on and on by selecting new groups and choosing between rows or columns. Here’s a layout with 8 containers, 4 rows and 2 columns: And here is a layout with 7 content areas; one row across the top of the screen and three rows with two columns below that: When you select Choose Content and select a data item like Product it will populate all the controls within the container (row or column in a vertical stack) however you have complete control on what to display within each group. You can delete fields you don’t want to display and/or change their controls. You can also change the size of controls and how they display by changing the settings in the properties window. If you are in the Screen Designer (and not the customization mode like we are here) you can also drag-drop data items from the left-hand side of the screen to the content tree. Note, however, that not all areas of the tree will allow you to drop a data item if there is a binding already set to a different set of data. For instance you can’t drop a Customer ID into the same group as a Product if they originate from different entities. To get around this, all you need to do is create a new group and content area as shown above. Let’s take a more complex example that deals with more than just product. I want to design a complex screen that displays Products and their Category, as well as all the OrderDetails for which that product is selected. This time I will create a new screen and select List and Details, select the Products screen data, and include the related OrderDetails. However I’m going to totally change the layout so that a Product grid is at the top left and below that is the selected Product detail. Below that will be the Category text fields and image in two columns below. On the right side I want the OrderDetails grid to take up the whole right side of the screen. All this can be done in customization mode while you’re debugging the application. To do this, I first deleted all the content items in the tree and then re-created the content tree as shown in the image below. I also set the image to be larger and the description textbox to be 5 rows using the property window below the live preview. I added the green lines to indicate the containers and show how it maps to the content tree (click to enlarge): I hope this demystifies the screen designer a little bit. Remember that screen templates are excellent starting points – you can take them as-is or customize them further. It takes a little fooling around with customizing screens to get them to do exactly what you want but there are a ton of possibilities once you get the hang of it. Stay tuned for more information on how to create your own screen templates that show up in the “Add New Screen” dialog. Enjoy!

• ANTS CLR and Memory Profiler In Depth Review (Part 2 of 2 &ndash; Memory Profiler)

  - by ToStringTheory

  One of the things that people might not know about me, is my obsession to make my code as efficient as possible. Many people might not realize how much of a task or undertaking that this might be, but it is surely a task as monumental as climbing Mount Everest, except this time it is a challenge for the mind… In trying to make code efficient, there are many different factors that play a part – size of project or solution, tiers, language used, experience and training of the programmer, technologies used, maintainability of the code – the list can go on for quite some time. I spend quite a bit of time when developing trying to determine what is the best way to implement a feature to accomplish the efficiency that I look to achieve. One program that I have recently come to learn about – Red Gate ANTS Performance (CLR) and Memory profiler gives me tools to accomplish that job more efficiently as well. In this review, I am going to cover some of the features of the ANTS memory profiler set by compiling some hideous example code to test against. Notice As a member of the Geeks With Blogs Influencers program, one of the perks is the ability to review products, in exchange for a free license to the program. I have not let this affect my opinions of the product in any way, and Red Gate nor Geeks With Blogs has tried to influence my opinion regarding this product in any way. Introduction – Part 2 In my last post, I reviewed the feature packed Red Gate ANTS Performance Profiler.  Separate from the Red Gate Performance Profiler is the Red Gate ANTS Memory Profiler – a simple, easy to use utility for checking how your application is handling memory management…  A tool that I wish I had had many times in the past.  This post will be focusing on the ANTS Memory Profiler and its tool set. The memory profiler has a large assortment of features just like the Performance Profiler, with the new session looking nearly exactly alike: ANTS Memory Profiler Memory profiling is not something that I have to do very often…  In the past, the few cases I’ve had to find a memory leak in an application I have usually just had to trace the code of the operations being performed to look for oddities…  Sadly, I have come across more undisposed/non-using’ed IDisposable objects, usually from ADO.Net than I would like to ever see.  Support is not fun, however using ANTS Memory Profiler makes this task easier.  For this round of testing, I am going to use the same code from my previous example, using the WPF application. This time, I will choose the ‘Profile Memory’ option from the ANTS menu in Visual Studio, which launches the solution in its currently configured state/start-up project, and then launches the ANTS Memory Profiler to help.  It prepopulates all of the fields with the current project information, and all I have to do is select the ‘Start Profiling’ option. When the window comes up, it is actually quite barren, just giving ideas on how to work the profiler.  You start by getting to the point in your application that you want to profile, and then taking a ‘Memory Snapshot’.  This performs a full garbage collection, and snapshots the managed heap.  Using the same WPF app as before, I will go ahead and take a snapshot now. As you can see, ANTS is already giving me lots of information regarding the snapshot, however this is just a snapshot.  The whole point of the profiler is to perform an action, usually one where a memory problem is being noticed, and then take another snapshot and perform a diff between them to see what has changed.  I am going to go ahead and generate 5000 primes, and then take another snapshot: As you can see, ANTS is already giving me a lot of new information about this snapshot compared to the last.  Information such as difference in memory usage, fragmentation, class usage, etc…  If you take more snapshots, you can use the dropdown at the top to set your actual comparison snapshots. If you beneath the timeline, you will see a breadcrumb trail showing how best to approach profiling memory using ANTS.  When you first do the comparison, you start on the Summary screen.  You can either use the charts at the bottom, or switch to the class list screen to get to the next step.  Here is the class list screen: As you can see, it lists information about all of the instances between the snapshots, as well as at the bottom giving you a way to filter by telling ANTS what your problem is.  I am going to go ahead and select the Int16[] to look at the Instance Categorizer Using the instance categorizer, you can travel backwards to see where all of the instances are coming from.  It may be hard to see in this image, but hopefully the lightbox (click on it) will help: I can see that all of these instances are rooted to the application through the UI TextBlock control.  This image will probably be even harder to see, however using the ‘Instance Retention Graph’, you can trace an objects memory inheritance up the chain to see its roots as well.  This is a simple example, as this is simply a known element.  Usually you would be profiling an actual problem, and comparing those differences.  I know in the past, I have spotted a problem where a new context was created per page load, and it was rooted into the application through an event.  As the application began to grow, performance and reliability problems started to emerge.  A tool like this would have been a great way to identify the problem quickly. Overview Overall, I think that the Red Gate ANTS Memory Profiler is a great utility for debugging those pesky leaks.  3 Biggest Pros: Easy to use interface with lots of options for configuring profiling session Intuitive and helpful interface for drilling down from summary, to instance, to root graphs ANTS provides an API for controlling the profiler. Not many options, but still helpful. 2 Biggest Cons: Inability to automatically snapshot the memory by interval Lack of complete integration with Visual Studio via an extension panel Ratings Ease of Use (9/10) – I really do believe that they have brought simplicity to the once difficult task of memory profiling.  I especially liked how it stepped you further into the drilldown by directing you towards the best options. Effectiveness (10/10) – I believe that the profiler does EXACTLY what it purports to do.  Features (7/10) – A really great set of features all around in the application, however, I would like to see some ability for automatically triggering snapshots based on intervals or framework level items such as events. Customer Service (10/10) – My entire experience with Red Gate personnel has been nothing but good.  their people are friendly, helpful, and happy! UI / UX (9/10) – The interface is very easy to get around, and all of the options are easy to find.  With a little bit of poking around, you’ll be optimizing Hello World in no time flat! Overall (9/10) – Overall, I am happy with the Memory Profiler and its features, as well as with the service I received when working with the Red Gate personnel.  Thank you for reading up to here, or skipping ahead – I told you it would be shorter!  Please, if you do try the product, drop me a message and let me know what you think!  I would love to hear any opinions you may have on the product.

• How to use onSensorChanged sensor data in combination with OpenGL

  - by Sponge

  I have written a TestSuite to find out how to calculate the rotation angles from the data you get in SensorEventListener.onSensorChanged(). I really hope you can complete my solution to help people who will have the same problems like me. Here is the code, i think you will understand it after reading it. Feel free to change it, the main idea was to implement several methods to send the orientation angles to the opengl view or any other target which would need it. method 1 to 4 are working, they are directly sending the rotationMatrix to the OpenGl view. all other methods are not working or buggy and i hope someone knows to get them working. i think the best method would be method 5 if it would work, because it would be the easiest to understand but i'm not sure how efficient it is. the complete code isn't optimized so i recommend to not use it as it is in your project. here it is: import java.nio.ByteBuffer;

• Driver error when using multiple shaders

  - by Jinxi

  I'm using 3 different shaders: a tessellation shader to use the tessellation feature of DirectX11 :) a regular shader to show how it would look without tessellation and a text shader to display debug-info such as FPS, model count etc. All of these shaders are initialized at the beginning. Using the keyboard, I can switch between the tessellation shader and regular shader to render the scene. Additionally, I also want to be able toggle the display of debug-info using the text shader. Since implementing the tessellation shader the text shader doesn't work anymore. When I activate the DebugText (rendered using the text-shader) my screens go black for a while, and Windows displays the following message: Display Driver stopped responding and has recovered This happens with either of the two shaders used to render the scene. Additionally: I can start the application using the regular shader to render the scene and then switch to the tessellation shader. If I try to switch back to the regular shader I get the same error as with the text shader. What am I doing wrong when switching between shaders? What am I doing wrong when displaying text at the same time? What file can I post to help you help me? :) thx P.S. I already checked if my keyinputs interrupt at the wrong time (during render or so..), but that seems to be ok Testing Procedure Regular Shader without text shader Add text shader to Regular Shader by keyinput (works now, I built the text shader back to only vertex and pixel shader) (somthing with the z buffer is stil wrong...) Remove text shader, then change shader to Tessellation Shader by key input Then if I add the Text Shader or switch back to the Regular Shader Switching/Render Shader Here the code snipet from the Renderer.cpp where I choose the Shader according to the boolean "m_useTessellationShader": if(m_useTessellationShader) { // Render the model using the tesselation shader ecResult = m_ShaderManager->renderTessellationShader(m_D3D->getDeviceContext(), meshes[lod_level]->getIndexCount(), worldMatrix, viewMatrix, projectionMatrix, textures, texturecount, m_Light->getDirection(), m_Light->getAmbientColor(), m_Light->getDiffuseColor(), (D3DXVECTOR3)m_Camera->getPosition(), TESSELLATION_AMOUNT); } else { // todo: loaded model depends on distance to camera // Render the model using the light shader. ecResult = m_ShaderManager->renderShader(m_D3D->getDeviceContext(), meshes[lod_level]->getIndexCount(), lod_level, textures, texturecount, m_Light->getDirection(), m_Light->getAmbientColor(), m_Light->getDiffuseColor(), worldMatrix, viewMatrix, projectionMatrix); } And here the code snipet from the Mesh.cpp where I choose the Typology according to the boolean "useTessellationShader": // RenderBuffers is called from the Render function. The purpose of this function is to set the vertex buffer and index buffer as active on the input assembler in the GPU. Once the GPU has an active vertex buffer it can then use the shader to render that buffer. void Mesh::renderBuffers(ID3D11DeviceContext* deviceContext, bool useTessellationShader) { unsigned int stride; unsigned int offset; // Set vertex buffer stride and offset. stride = sizeof(VertexType); offset = 0; // Set the vertex buffer to active in the input assembler so it can be rendered. deviceContext->IASetVertexBuffers(0, 1, &m_vertexBuffer, &stride, &offset); // Set the index buffer to active in the input assembler so it can be rendered. deviceContext->IASetIndexBuffer(m_indexBuffer, DXGI_FORMAT_R32_UINT, 0); // Check which Shader is used to set the appropriate Topology // Set the type of primitive that should be rendered from this vertex buffer, in this case triangles. if(useTessellationShader) { deviceContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_3_CONTROL_POINT_PATCHLIST); }else{ deviceContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST); } return; } RenderShader Could there be a problem using sometimes only vertex and pixel shader and after switching using vertex, hull, domain and pixel shader? Here a little overview of my architecture: TextClass: uses font.vs and font.ps deviceContext-VSSetShader(m_vertexShader, NULL, 0); deviceContext-PSSetShader(m_pixelShader, NULL, 0); deviceContext-PSSetSamplers(0, 1, &m_sampleState); RegularShader: uses vertex.vs and pixel.ps deviceContext-VSSetShader(m_vertexShader, NULL, 0); deviceContext-PSSetShader(m_pixelShader, NULL, 0); deviceContext-PSSetSamplers(0, 1, &m_sampleState); TessellationShader: uses tessellation.vs, tessellation.hs, tessellation.ds, tessellation.ps deviceContext-VSSetShader(m_vertexShader, NULL, 0); deviceContext-HSSetShader(m_hullShader, NULL, 0); deviceContext-DSSetShader(m_domainShader, NULL, 0); deviceContext-PSSetShader(m_pixelShader, NULL, 0); deviceContext-PSSetSamplers(0, 1, &m_sampleState); ClearState I'd like to switch between 2 shaders and it seems they have different context parameters, right? In clearstate methode it says it resets following params to NULL: I found following in my Direct3D Class: depth-stencil state - m_deviceContext-OMSetDepthStencilState rasterizer state - m_deviceContext-RSSetState(m_rasterState); blend state - m_device-CreateBlendState viewports - m_deviceContext-RSSetViewports(1, &viewport); I found following in every Shader Class: input/output resource slots - deviceContext-PSSetShaderResources shaders - deviceContext-VSSetShader to - deviceContext-PSSetShader input layouts - device-CreateInputLayout sampler state - device-CreateSamplerState These two I didn't understand, where can I find them? predications - ? scissor rectangles - ? Do I need to store them all localy so I can switch between them, because it doesn't feel right to reinitialize the Direct3d and the Shaders by every switch (key input)?!

• A*, Tile costs and heuristic; How to approach

  - by Kevin Toet

  I'm doing exercises in tile games and AI to improve my programming. I've written a highly unoptimised pathfinder that does the trick and a simple tile class. The first problem i ran into was that the heuristic was rounded to int's which resulted in very straight paths. Resorting a Euclidian Heuristic seemed to fixed it as opposed to use the Manhattan approach. The 2nd problem I ran into was when i tried added tile costs. I was hoping to use the value's of the flags that i set on the tiles but the value's were too small to make the pathfinder consider them a huge obstacle so i increased their value's but that breaks the flags a certain way and no paths were found anymore. So my questions, before posting the code, are: What am I doing wrong that the Manhatten heuristic isnt working? What ways can I store the tile costs? I was hoping to (ab)use the enum flags for this The path finder isnt considering the chance that no path is available, how do i check this? Any code optimisations are welcome as I'd love to improve my coding. public static List<Tile> FindPath( Tile startTile, Tile endTile, Tile[,] map ) { return FindPath( startTile, endTile, map, TileFlags.WALKABLE ); } public static List<Tile> FindPath( Tile startTile, Tile endTile, Tile[,] map, TileFlags acceptedFlags ) { List<Tile> open = new List<Tile>(); List<Tile> closed = new List<Tile>(); open.Add( startTile ); Tile tileToCheck; do { tileToCheck = open[0]; closed.Add( tileToCheck ); open.Remove( tileToCheck ); for( int i = 0; i < tileToCheck.neighbors.Count; i++ ) { Tile tile = tileToCheck.neighbors[ i ]; //has the node been processed if( !closed.Contains( tile ) && ( tile.flags & acceptedFlags ) != 0 ) { //Not in the open list? if( !open.Contains( tile ) ) { //Set G int G = 10; G += tileToCheck.G; //Set Parent tile.parentX = tileToCheck.x; tile.parentY = tileToCheck.y; tile.G = G; //tile.H = Math.Abs(endTile.x - tile.x ) + Math.Abs( endTile.y - tile.y ) * 10; //TODO omg wtf and other incredible stories tile.H = Vector2.Distance( new Vector2( tile.x, tile.y ), new Vector2(endTile.x, endTile.y) ); tile.Cost = tile.G + tile.H + (int)tile.flags; //Calculate H; Manhattan style open.Add( tile ); } //Update the cost if it is else { int G = 10;//cost of going to non-diagonal tiles G += map[ tile.parentX, tile.parentY ].G; //If this path is shorter (G cost is lower) then change //the parent cell, G cost and F cost. if ( G < tile.G ) //if G cost is less, { tile.parentX = tileToCheck.x; //change the square's parent tile.parentY = tileToCheck.y; tile.G = G;//change the G cost tile.Cost = tile.G + tile.H + (int)tile.flags; // add terrain cost } } } } //Sort costs open = open.OrderBy( o => o.Cost).ToList(); } while( tileToCheck != endTile ); closed.Reverse(); List<Tile> validRoute = new List<Tile>(); Tile currentTile = closed[ 0 ]; validRoute.Add( currentTile ); do { //Look up the parent of the current cell. currentTile = map[ currentTile.parentX, currentTile.parentY ]; currentTile.renderer.material.color = Color.green; //Add tile to list validRoute.Add( currentTile ); } while ( currentTile != startTile ); validRoute.Reverse(); return validRoute; } And my Tile class: [Flags] public enum TileFlags: int { NONE = 0, DIRT = 1, STONE = 2, WATER = 4, BUILDING = 8, //handy WALKABLE = DIRT | STONE | NONE, endofenum } public class Tile : MonoBehaviour { //Tile Properties public int x, y; public TileFlags flags = TileFlags.DIRT; public Transform cachedTransform; //A* properties public int parentX, parentY; public int G; public float Cost; public float H; public List<Tile> neighbors = new List<Tile>(); void Awake() { cachedTransform = transform; } }

• OpenGL problem with FBO integer texture and color attachment

  - by Grieverheart

  In my simple renderer, I have 2 FBOs one that contains diffuse, normals, instance ID and depth in that order and one that I use store the ssao result. The textures I use for the first FBO are RGB8, RGBA16F, R32I and GL_DEPTH_COMPONENT32F for the depth. For the second FBO I use an R16F texture. My rendering process is to first render to everything I mentioned in the first FBO, then bind depth and normals textures for reading for the ssao pass and write to the second FBO. After that I bind the second FBO's texture for reading in my blur shader and bind the first FBO for writing. What I intend to do is to write the blurred ssao value to the alpha component of the Normals texture. Here are where the problems start. First of all, I use shading language 3.3, which my graphics card does support. I manage ouputs in my shaders using layout(location = #). Now, the normals texture should be bound to color attachment 1, but when I use 1, it seems to write to my diffuse texture which should be in color attachment 0. When I instead use layout(location = 0), it gets correctly written to my normals texture. Besides this, my instance ID texture also gets resets after running the blur shader which is weird because if I use a float texture and write to it instanceID / nInstances, the texture doesn't get reset after the blur shader has ran. Here is how I prepare my first FBO: bool CGBuffer::Init(unsigned int WindowWidth, unsigned int WindowHeight){ //Create FBO glGenFramebuffers(1, &m_fbo); glBindFramebuffer(GL_DRAW_FRAMEBUFFER, m_fbo); //Create gbuffer and Depth Buffer Textures glGenTextures(GBUFF_NUM_TEXTURES, &m_textures[0]); glGenTextures(1, &m_depthTexture); //prepare gbuffer for(unsigned int i = 0; i < GBUFF_NUM_TEXTURES; i++){ glBindTexture(GL_TEXTURE_2D, m_textures[i]); if(i == GBUFF_TEXTURE_TYPE_NORMAL) glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA16F, WindowWidth, WindowHeight, 0, GL_RGBA, GL_FLOAT, NULL); else if(i == GBUFF_TEXTURE_TYPE_DIFFUSE) glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB8, WindowWidth, WindowHeight, 0, GL_RGB, GL_FLOAT, NULL); else if(i == GBUFF_TEXTURE_TYPE_ID) glTexImage2D(GL_TEXTURE_2D, 0, GL_R32I, WindowWidth, WindowHeight, 0, GL_RED_INTEGER, GL_INT, NULL); else{ std::cout << "Error in FBO initialization" << std::endl; return false; } glFramebufferTexture2D(GL_DRAW_FRAMEBUFFER, GL_COLOR_ATTACHMENT0 + i, GL_TEXTURE_2D, m_textures[i], 0); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP); } //prepare depth buffer glBindTexture(GL_TEXTURE_2D, m_depthTexture); glTexImage2D(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT32F, WindowWidth, WindowHeight, 0, GL_DEPTH_COMPONENT, GL_FLOAT, NULL); glFramebufferTexture2D(GL_DRAW_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_TEXTURE_2D, m_depthTexture, 0); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_COMPARE_MODE, GL_NONE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP); GLenum DrawBuffers[] = {GL_COLOR_ATTACHMENT0, GL_COLOR_ATTACHMENT1, GL_COLOR_ATTACHMENT2}; glDrawBuffers(GBUFF_NUM_TEXTURES, DrawBuffers); GLenum Status = glCheckFramebufferStatus(GL_FRAMEBUFFER); if(Status != GL_FRAMEBUFFER_COMPLETE){ std::cout << "FB error, status 0x" << std::hex << Status << std::endl; return false; } //Restore default framebuffer glBindFramebuffer(GL_FRAMEBUFFER, 0); return true; } where I use an enum defined as, enum GBUFF_TEXTURE_TYPE{ GBUFF_TEXTURE_TYPE_DIFFUSE, GBUFF_TEXTURE_TYPE_NORMAL, GBUFF_TEXTURE_TYPE_ID, GBUFF_NUM_TEXTURES }; Am I missing some kind of restriction? Does the color attachment of the FBO's textures somehow gets reset i.e. I'm using a re-size function which re-sizes the textures of the FBO but should I perhaps call glFramebufferTexture2D again too? EDIT: Here is the shader in question: #version 330 core uniform sampler2D aoSampler; uniform vec2 TEXEL_SIZE; // x = 1/res x, y = 1/res y uniform bool use_blur; noperspective in vec2 TexCoord; layout(location = 0) out vec4 out_AO; void main(void){ if(use_blur){ float result = 0.0; for(int i = -1; i < 2; i++){ for(int j = -1; j < 2; j++){ vec2 offset = vec2(TEXEL_SIZE.x * i, TEXEL_SIZE.y * j); result += texture(aoSampler, TexCoord + offset).r; // -0.004 because the texture seems to be a bit displaced } } out_AO = vec4(vec3(0.0), result / 9); } else out_AO = vec4(vec3(0.0), texture(aoSampler, TexCoord).r); }

Can anyone suggest either the (probably small) java method to represent this intention or a really good resource specifically about programming dynamic stuff in RichFaces using java? Naturally I've read the javadocs, but they don't give me a concrete example of some JSF, the associated backing bean java code, and a screen shot of the resulting component. It may be asking a bit much, but I'm sure I'm not alone in thinking that with these three, I'd be able to understand the idea and apply it to many other component types in this family. The RF demo doesn't include dynamic panelMenus or drop downs so I'm a bit stumped.

• How to fix a Sticky Footer that works, but after a browser window is resized, the footer overlaps.

  - by UXdesigner

  Good day, I've been trying to build a perfect footer who sticks at the bottom of the browser window after it's content. And I got help here @ Stack Overflow previously. But after a while, and doing a few tests, found out that after the browser window is resized, and then I scroll down , the footer overlaps...it is causing me a big headache right now and I'd like to fix this so I can move on. I'm going to post the display.css right here: @charset "utf-8"; body, html { margin: 0; padding: 0; text-align: center; position: relative; min-height:100%; /* needed for footer positioning*/ height:100%; /* needed for footer positioning*/ } .spacer { clear: both; height: 0; margin: 0; padding: 0; font-size: 0.1em; } .spacer_left { clear: left; margin: 0 0 10px 0; padding: 0; font-size: 0.1em; } hr { height: 1px;

• Looking for a workaround for IE 6/7 "Unspecified Error" bug when accessing offsetParent; using ASP.N

  - by CodeChef

  I'm using jQuery UI's draggable and droppable libraries in a simple ASP.NET proof of concept application. This page uses the ASP.NET AJAX UpdatePanel to do partial page updates. The page allows a user to drop an item into a trashcan div, which will invoke a postback that deletes a record from the database, then rebinds the list (and other controls) that the item was drug from. All of these elements (the draggable items and the trashcan div) are inside an ASP.NET UpdatePanel. Here is the dragging and dropping initialization script: function initDragging() { $(".person").draggable({helper:'clone'}); $("#trashcan").droppable({ accept: '.person', tolerance: 'pointer', hoverClass: 'trashcan-hover', activeClass: 'trashcan-active', drop: onTrashCanned }); } $(document).ready(function(){ initDragging(); var prm = Sys.WebForms.PageRequestManager.getInstance(); prm.add_endRequest(function() { initDragging(); }); }); function onTrashCanned(e,ui) { var id = $('input[id$=hidID]', ui.draggable).val(); if (id != undefined) { $('#hidTrashcanID').val(id); __doPostBack('btnTrashcan',''); } } When the page posts back, partially updating the UpdatePanel's content, I rebind the draggables and droppables. When I then grab a draggable with my cursor, I get an "htmlfile: Unspecified error." exception. I can resolve this problem in the jQuery library by replacing elem.offsetParent with calls to this function that I wrote: function IESafeOffsetParent(elem) { try { return elem.offsetParent; } catch(e) { return document.body; } } I also have to avoid calls to elem.getBoundingClientRect() as it throws the same error. For those interested, I only had to make these changes in the jQuery.fn.offset function in the Dimensions Plugin. My questions are: Although this works, are there better ways (cleaner; better performance; without having to modify the jQuery library) to solve this problem? If not, what's the best way to manage keeping my changes in sync when I update the jQuery libraries in the future? For, example can I extend the library somewhere other than just inline in the files that I download from the jQuery website. Update: @some It's not publicly accessible, but I will see if SO will let me post the relevant code into this answer. Just create an ASP.NET Web Application (name it DragAndDrop) and create these files. Don't forget to set Complex.aspx as your start page. You'll also need to download the jQuery UI drag and drop plug in as well as jQuery core Complex.aspx <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Complex.aspx.cs" Inherits="DragAndDrop.Complex" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> <script src="jquery-1.2.6.min.js" type="text/javascript"></script> <script src="jquery-ui-personalized-1.5.3.min.js" type="text/javascript"></script> <script type="text/javascript"> function initDragging() { $(".person").draggable({helper:'clone'});

• PHP SOAP error: Method element needs to belong to the namespace

  - by kdm

  I'm unable to retrieve data from an XML document, any help is greatly appreciated. I'm using PHP 5.2.10 and the WSDL url is an internal link within my company. The following code produces an error. $url = "http://dta-info/IVR/IVRINFO?WSDL"; $params = array("zANI" => "12345"); try{ $client = new SoapClient($url, array( 'trace' => 1, 'connection_timeout' => 2, 'location' => $url ) ); }catch(SoapFault $fault){ echo "faultstring: {$fault->faultstring})\n"; } try{ $result = $client->GetIVRinfo($params); }catch(SoapFault $fault){ echo "(faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring} )\n"; } (faultcode: SOAP-ENV:Client, faultstring: There should be no path or parameters after a SOAP vname. ) So i tried to use a non-wsdl mode but i receive a different error no matter how i try to format the params. $url = "http://dta-info/IVR/IVRINFO"; $params = array("zANI" => "12345"); try{ $client = new SoapClient(null, array( 'trace' => 1, 'connection_timeout' => 2, 'location' => $url, 'uri' => $uri, 'style' => SOAP_DOCUMENT, 'use' => SOAP_LITERAL, 'soap_version' => SOAP_2 ) ); }catch(SoapFault $fault){ echo "faultstring: {$fault->faultstring})\n"; } try{ $result = $client->GetIVRinfo($params); }catch(SoapFault $fault){ echo "(faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring} )\n"; } (faultcode: SOAP-ENV:Client, faultstring: The method element needs to belong to the namespace 'http://GETIVRINFO/IVR/IVRINFO'. ) I have tested this WSDL with a tool called SoapUI and it returns the results with no errors. So it leads me to believe I'm not formatting the vars or headers correctly with PHP. I also tried passing in a xml fragment as the param but that returns the same error. What am i doing wrong?????? $params = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ivr="http://GETIVRINFO/IVR/IVRINFO"> <soapenv:Header/> <soapenv:Body> <ivr:GetIVRinfo> <!--Optional:--> <ivr:zANI>12345</ivr:zANI> </ivr:GetIVRinfo> </soapenv:Body> </soapenv:Envelope>'; Here is the WSDL document: <?xml version="1.0"?><wsdl:definitions name="IVR"

This is running on iphone with jquery mobile + phonegap I made a video to make the issue clear: http://www.youtube.com/watch?v=Ybvzh_wTnSE <body style="background-color: #000;"> <div id="container" style="display:none;"> <div id="side-menu" style="display:none;"> <div id="header_top"></div> <a href="#dives" onclick="showdives();"><div id="header_dives" class="selected"></div></a> <div id="header_spacer1"></div> <a href="#explore" onclick="showexplore();"><div id="header_explore"></div></a> <div id="header_spacer2"></div> <a href="#search" onclick="showsearch();"><div id="header_search"></div></a> <div id="header_spacer3"></div> <a href="#settings" onclick="showsettings();"><div id="header_settings"></div></a> <div id="header_bottom"></div> </div> <div id="slide_mask"> <!-- START of LOGIN page --> <div data-role="page" id="login"> <div id="home_frame"> <div id="home_logo"></div> <div id="home_fblogin" onclick="login()"></div> <div class="home_login"> <p>Email: <input type="text" name="user[email]" size="30"/></p> <p>Password: <input type="password" name="user[password]" size="30"/></p> <button onclick="show_page_home();">LOGIN</button> </div> </div> </div> <!-- END of LOGIN page --> <!-- START of LOGIN page --> <div data-role="page" id="dives" class="right_pane"> <p>My dives !</p> </div><!-- /content --> <div data-role="page" id="explore" class="hidden right_pane"> <p>My explore !</p> </div><!-- /content --> <div data-role="page" id="search" class="hidden right_pane"> <p>My search !</p> </div><!-- /content --> <div data-role="page" id="settings" class="hidden right_pane"> <p>My settings !</p> <button onclick="logout_db();">logout</button> </div><!-- /content --> <!-- END of LOGIN page --> </div> </div> <div id="log"></div> <div id="data"></div> </body> And the relevant CSS: body {margin: 0;

• drop down menu will not display outside containing div in IE7..

  - by playahabana

  I am tearing my hair out over this, I have a dropdown menu using CSS and jQuery (thanks to Soh Tanaka) and it works perfectly in Firefox, Safari, Google chrome and I.E. 8, but in IE 7 it will not drop down outside the 'Banner div'. It drops below the nav div however. I have moved the nav div higher in the banner the result is the same, menu drops until it reaches the border of the banner div and then vanishes.... Below is the css. This is my first website and I have some limited understanding of what I am doing. The drop down menu includes transparent png's as links (I know, I know...but it's what the Boss wants...) please could someone take a quick scan at the below CSS and let me know what is wroong? Is this some form of the IE z-index bug? i have tried all different combinations of z-index and still I can't get a different result. . The html is below as well. Thankyou in advance #banner { position: relative; width: 62.5em; height: 12em; background-color: #46280A; background-image: url('images/includes/banner2.jpg'); background-repeat: no-repeat; background-position: center; -moz-box-shadow: -4px 6px 8px #000; -webkit-box-shadow: -4px 6px 8px #000; box-shadow: -4px 6px 8px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000'); z-index: 1; } /*------------------------------------SCROLLER---------------------------------------------*/ #headlines{ position: absolute; top: 1.3em; right: 2.75em; overflow: hidden; height: 2.5em; width: 24em; background-color: #000000; display: block; z-index: 3; } #news{ position: relative; height: 3.1em; line-height: 2.5em; font-size: 0.8em color: #FFFF99; white-space: nowrap; overflow: hidden; font-family: Georgia,Arial; } #scrollerglass{ position: absolute; top: 0.95em; right: 2em; height: 52px; width: 410px; border: none; padding: 0.2em 0em 0em 0em; line-height: 0.7em; text-align: center; background-image: url('images/includes/scrollerglass.png'); background-color: transparent; background-repeat: no-repeat; background-position: center; opacity: 20; z-index: 10; } #scrollerglass a i { visibility: hiddn ; } /-------------------------------------NAVIGATION-----------------------------------------/ #nav { position: absolute; top: 5.8em; left: 0.2em; font-family: trebuchet, sans-serif; font-size: 1em; line-height: 3.75em; text-align: center; color: #FFFF00; z-index: 3; } ul.navlist { list-style: none; padding: 0em; margin: 1em; float: left; width: 62.5em; background: transparent; font-size: 1em; } ul.navlist li { position: relative; /*--Declare X and Y axis base for sub navigation--*/ float: left; margin: 0em 1.4em; padding: 0em 0.7em 0em 0em; z-index: 1; } ul.navlist li a{ display: block; text-decoration: none; float: left; border: 0px solid; } ul.navlist li img{ border: 0px solid; } ul.navlist li span { trigger styles--*/ width: 1.2em; height: 5.25em; float: left; background: url(images/links/downlogo.png) no-repeat center top; } ul.navlist li span.subhover { background-position: center bottom; cursor: pointer; } ul.navlist li ul.navdrop { list-style: none; position: absolute; float: left; top: 5.3em; left: -2.4em; height: 15.0em; width: 11.25em; margin: 0; padding: 0.5em 0em 0em 0em; display: none; background-position: center; background-image: url('images/includes/slider.jpg'); background-color: transparent; background-repeat: no-repeat; -moz-box-shadow: -4px 6px 8px #000; -webkit-box-shadow: -4px 6px 8px #000; box-shadow: -4px 6px 8px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000'); z-index:1; } ul.navlist li ul.navdrop li{ margin: 0em 2.3em 0em 0em; padding: 1em 0em 0em 0em; width: 8em; clear: both; } html ul.navlist li ul.navdrop li a { border: 0px solid; width: 11.25em; } html ul.navlist li ul.navdrop li a:hover { background: transparent; } <div id="banner"> <div id="headlines"> <div id="news"> Whatever we want to promote </div> </div> <div id="scrollerglass"> <a href="vintagecigars.php"> <i>------s-c-r-o-l-l-e-r - - - -l-i-n-k-s--------<br /> <br>------s-c-r-o-l-l-e-r - - - -l-i-n-k-s------</i></a> </div> <div id="nav"> <ul class="navmenu"> <li><a href="index.php"><img src="images/links/home.png" alt="Home" ></a></li> <li><a href="ourbar.php"><img src="images/links/ourbar.png" alt="Our Bar" ></a> <ul class="navdrop"> <li ><a href="ourcocktails.php"><img src="images/links/cockteles.png" alt="Our Cocktails" ></a></li> <li ><a href="celebrate.php"><img src="images/links/celebrate.png" alt="Celebrate in Style" ></a></li> </ul> </li> <li><a href="ourcigars.php"><img src="images/links/ourcigars.png" alt="Our Cigars" ></a> <ul class="navdrop"> <li ><a href="edicioneslimitadas.php"><img src="images/links/edicioneslimitadas.png" alt="Edition Limitadas" ></a></li> <li ><a href="cigartasting.php"><img src="images/links/cigartasting.png" alt="Cigar Tastings" ></a></li> </ul> </li> <li><a href="personalroller.php"><img src="images/links/personalcigar.png" alt="Personal Cigar Roller" ></a></li> <li><a href="galleryentrance.php"><img src="images/links/photogallery.png" alt="Photo Gallery" ></a></li> <li><a href="contactus.php"><img src="images/links/contactus.png" alt="Contact Us" ></a></li> </ul></div></div><!--end banner-->

• How to normalize a word document?

  - by AngryHacker

  I was too cheap to hire someone to retype a really, really long scanned document full of legalese. So I OCRed it using OmniPage. But the OCR output was kind of disappointing. I got a word doc that has multiple line spacings. The before and after paragraph heights are different all over the place. This would be easy, if the entire document had the same paragraph settings, but it does not. There are probably a half dozen different styles going on. What is the easiest way to normalize the document? For instance, if one paragraph has a line spacing of 20.4 pt and another one has a spacing of 20.9 pt, then I'd like to consider them the same style and set them to a single value? Or really, any suggestion is welcome at this point.

• Windows Update when Group Policy Forbids

  - by David Beckman

  I am in the administrators group for my local Windows XP machine and I would like to get updates via http://update.microsoft.com/[1]. However, this is prevented via the group policy: Network policy settings prevent you from using this website to get updates for your computer. Is there anyway to override this specific policy for my machine or my user? [1] Several installed applications are Microsoft based, but are not part of the machine standard (eg Visual studio). As such, I am not getting the updates for these applications. I could periodically go to the various application sites and look for hotfixes, but that is beyond tedious.
