• OBI already has a caching mechanism in presentation layer and BI server layer. How is the new in-memory caching better for performance?

  - by Varun

  Question: OBI already has a caching mechanism in presentation layer and BI server layer. How is the new in-memory caching better for performance? Answer: OBI Caching only speeds up what has been seen before. An In-memory data structure generated by the summary advisor is optimized to provide maximum value by accounting for the expected broad usage and drilldowns. It is possible to adapt the in-memory data to seasonality by running the summary advisor on specific workloads. Moreover, the in-memory data is created in an analytic database providing maximum performance for the large amount of memory available.

• Consolidating multiple domain names

  - by Mike

  I have a client that has three separately hosted copies of their website, each on a separate domain name. The websites are all essentially the same, bar a few discrepancies caused by badly managed updates in the past. I will soon be launching a completely new website for them, at which point, all three domain names are to resolve to the same web server. One domain name will become the default domain name that they refer to in all their literature, and the other two will simply be used as catch-alls for old links, bookmarks, and so on. I would like to know what people consider the best route to achieve this. My plan so far is: Get the new site up and running on the new webserver. Change the relevant A record of the default domain name to point to the new webserver. a) Keep the existing hosting accounts in operation. Create a list of 301 redirects from old page names on the old site to new page names on the new site. or b) Configure CNAME records for the non-default domain names, each pointing to the new webserver. Create a list of 301 redirects on the new site that redirect from old page names to new page names. If my understanding is correct, 3a will help to maintain whatever search engine rankings the sites already have (I know it's not going to be perfect), while at the same time informing search engines that the old domain names are no longer in use. What's a good approach to take here?

• How to deal with elimination of duplicate logic vs. cost of complexity increase?

  - by Gabriel

  I just wrote some code that is very representative of a recurring theme (in my coding world lately): repeated logic leads to an instinct to eliminate duplication which results in something that is more complex the tradeoff seems wrong to me (the examples of the negative side aren't worth posting - but this is probably the 20th console utility I've written in the past 12 months). I'm curious if I'm missing some techniques or if this is really just on of those "experience tells you when to do what" type of issues. Here's the code... I'm tempted to leave it as is, even though there will be about 20 of those if-blocks when I'm done. static void Main(string[] sargs) { try { var urls = new DirectTrackRestUrls(); var restCall = new DirectTrackRestCall(); var logger = new ConsoleLogger(); Args args = (Args)Enum.Parse(typeof(Args), string.Join(",", sargs)); if (args.HasFlag(Args.Campaigns)) { var getter = new ResourceGetter(logger, urls.ListAdvertisers, restCall); restCall.UriVariables.Add("access_id", 1); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } if (args.HasFlag(Args.Advertisers)) { var getter = new ResourceGetter(logger, urls.ListAdvertisers, restCall); restCall.UriVariables.Add("access_id", 1); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } if (args.HasFlag(Args.CampaignGroups)) { var getter = new ResourceGetter(logger, urls.ListCampaignGroups, restCall); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } } catch (Exception e) { Console.WriteLine(e.InnerException); Console.WriteLine(e.StackTrace); }

• Installed Ubuntu 14.04. How do I get it working with my new AMD R9 280X. When I run it I get garbage on the display

  - by user289455

  I installed Ubuntu 14.04 on my Gigabyte A88X FM2+ motherboard and A10 7700K processor. Everything worked perfectly. This system is dual booted with Windows 8.1 for gaming and I installed subsequently I installed an AMD r9 280X gpu. Windows was easy. It kept working with the new card installed and I just needed to download and instal the driver. Reboot and it's done. Ubuntu boots into a blank display. I enter the password and can log in. The menu on the left and bar at the top are visible but when I try to open an app, I get blocks and rubbish on the display. My preference is not to remove the card. So, my question is: What would be the procedure I could follow where I can log in using a text based terminal and download and install the AMD drivers.

• Farseer circle hangs where it's spawned

  - by necrosmash

  I'm currently trying to simply spawn a circle in Farseer. However, it's stuck wherever I spawn it! The game is updating fine, as I can see the circle spinning in place when I spawn it because of how I currently have gravity set up (following code from Game1.cs): // Initialise the screen center for use with // the Level class screenCenter = new Vector2(graphics.GraphicsDevice.Viewport.Width / 2f, graphics.GraphicsDevice.Viewport.Height / 2f); world = new World(new Vector2(20, 20)); currentLevel = new Level1(screenCenter, circleSprite, groundSprite, ref world); Level1 constructor: public Level1(Vector2 screenCenter, Texture2D circleSprite, Texture2D groundSprite, ref World world) { player = new Player(ref world, screenCenter, circleSprite); ground = new Ground(ref world, screenCenter, groundSprite); listLevelItems = new List<LevelItem>(); listLevelItems.Add(player); listLevelItems.Add(ground); } Player constructor: public Player(ref World world, Vector2 screenCenter, Texture2D sprite) { setSprite(sprite); setPosition((screenCenter / MeterInPixels) + new Vector2(0f, 0f)); playerBody = BodyFactory.CreateCircle(world, 96f / (2f * MeterInPixels), 1f, playerPosition); getBody().BodyType = BodyType.Dynamic; // Ball bounce and friction getBody().Restitution = 0.3f; getBody().Friction = 0.5f; } If I use a breakpoint and change the playerBody position while the game is halted, the ball does move, but stays fixed in its new location. Any help would be greatly appreciated.

• Flash and Google Maps - Only Last Icon showing

  - by Peter

  I have a simple Map and geocoding sample in Flash using CS4 The problem is simple - I can retrieve a short list from the google search api, but when I try to generate the icons on the map using a loop, only the last icon is displayed. (ignore the house icon, it is generated earlier) I feel I am missing something or made a stupid AS3 mistake (like treating it as if it was c#) - or even a stupid wood-for-the-trees mistake. The problem is in the last line of the code. I have added all my code just in case somebody else can find a use for it - lord knows it took me a great while to figure this out :) It runs here (also, if anybody has an idea why the icon is slightly in the wrong place on render, but corrects if you move the map - please let me know) Any help would be great. Thanks.

• Using jQuery and OData to Insert a Database Record

  - by Stephen Walther

  In my previous blog entry, I explored two ways of inserting a database record using jQuery. We added a new Movie to the Movie database table by using a generic handler and by using a WCF service. In this blog entry, I want to take a brief look at how you can insert a database record using OData. Introduction to OData The Open Data Protocol (OData) was developed by Microsoft to be an open standard for communicating data across the Internet. Because the protocol is compatible with standards such as REST and JSON, the protocol is particularly well suited for Ajax. OData has undergone several name changes. It was previously referred to as Astoria and ADO.NET Data Services. OData is used by Sharepoint Server 2010, Azure Storage Services, Excel 2010, SQL Server 2008, and project code name “Dallas.” Because OData is being adopted as the public interface of so many important Microsoft technologies, it is a good protocol to learn. You can learn more about OData by visiting the following websites: http://www.odata.org http://msdn.microsoft.com/en-us/data/bb931106.aspx When using the .NET framework, you can easily expose database data through the OData protocol by creating a WCF Data Service. In this blog entry, I will create a WCF Data Service that exposes the Movie database table. Create the Database and Data Model The MoviesDB database is a simple database that contains the following Movies table: You need to create a data model to represent the MoviesDB database. In this blog entry, I use the ADO.NET Entity Framework to create my data model. However, WCF Data Services and OData are not tied to any particular OR/M framework such as the ADO.NET Entity Framework. For details on creating the Entity Framework data model for the MoviesDB database, see the previous blog entry. Create a WCF Data Service You create a new WCF Service by selecting the menu option Project, Add New Item and selecting the WCF Data Service item template (see Figure 1). Name the new WCF Data Service MovieService.svc. Figure 1 – Adding a WCF Data Service Listing 1 contains the default code that you get when you create a new WCF Data Service. There are two things that you need to modify. Listing 1 – New WCF Data Service File using System; using System.Collections.Generic; using System.Data.Services; using System.Data.Services.Common; using System.Linq; using System.ServiceModel.Web; using System.Web; namespace WebApplication1 { public class MovieService : DataService< /* TODO: put your data source class name here */ > { // This method is called only once to initialize service-wide policies. public static void InitializeService(DataServiceConfiguration config) { // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc. // Examples: // config.SetEntitySetAccessRule("MyEntityset", EntitySetRights.AllRead); // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } } First, you need to replace the comment /* TODO: put your data source class name here */ with a class that represents the data that you want to expose from the service. In our case, we need to replace the comment with a reference to the MoviesDBEntities class generated by the Entity Framework. Next, you need to configure the security for the WCF Data Service. By default, you cannot query or modify the movie data. We need to update the Entity Set Access Rule to enable us to insert a new database record. The updated MovieService.svc is contained in Listing 2: Listing 2 – MovieService.svc using System.Data.Services; using System.Data.Services.Common; namespace WebApplication1 { public class MovieService : DataService<MoviesDBEntities> { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("Movies", EntitySetRights.AllWrite); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } } That’s all we have to do. We can now insert a new Movie into the Movies database table by posting a new Movie to the following URL: /MovieService.svc/Movies The request must be a POST request. The Movie must be represented as JSON. Using jQuery with OData The HTML page in Listing 3 illustrates how you can use jQuery to insert a new Movie into the Movies database table using the OData protocol. Listing 3 – Default.htm <!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> <title>jQuery OData Insert</title> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="Scripts/json2.js" type="text/javascript"></script> </head> <body> <form> <label>Title:</label> <input id="title" /> <br /> <label>Director:</label> <input id="director" /> </form> <button id="btnAdd">Add Movie</button> <script type="text/javascript"> $("#btnAdd").click(function () { // Convert the form into an object var data = { Title: $("#title").val(), Director: $("#director").val() }; // JSONify the data var data = JSON.stringify(data); // Post it $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "MovieService.svc/Movies", data: data, dataType: "json", success: insertCallback }); }); function insertCallback(result) { // unwrap result var newMovie = result["d"]; // Show primary key alert("Movie added with primary key " + newMovie.Id); } </script> </body> </html> jQuery does not include a JSON serializer. Therefore, we need to include the JSON2 library to serialize the new Movie that we wish to create. The Movie is serialized by calling the JSON.stringify() method: var data = JSON.stringify(data); You can download the JSON2 library from the following website: http://www.json.org/js.html The jQuery ajax() method is called to insert the new Movie. Notice that both the contentType and dataType are set to use JSON. The jQuery ajax() method is used to perform a POST operation against the URL MovieService.svc/Movies. Because the POST payload contains a JSON representation of a new Movie, a new Movie is added to the database table of Movies. When the POST completes successfully, the insertCallback() method is called. The new Movie is passed to this method. The method simply displays the primary key of the new Movie: Summary The OData protocol (and its enabling technology named WCF Data Services) works very nicely with Ajax. By creating a WCF Data Service, you can quickly expose your database data to an Ajax application by taking advantage of open standards such as REST, JSON, and OData. In the next blog entry, I want to take a closer look at how the OData protocol supports different methods of querying data.

• You are probably NOT a SharePoint Development Expert if&hellip;

  - by Mark Rackley

  So, all you aspiring SharePoint experts out there (especially those of you who put “expert” in your resumes).  It’s time for a cold cool splash of reality. More than likely you are NOT an expert (I know I’m not). Yes, you may have some expertise in certain aspects in SharePoint (it’s questionable if I have THAT some days), but make sure you’ve got the basics down before you start throwing that word “expert” around. I know that it becomes frustrating to those looking to hire SharePoint people and having to sift through all the resumes of those who think very highly of themselves and their skills only to find those gaping holes in common best practices. I’m much more willing to hire a decent dev who KNOWS they are not an expert than to hire a decent+ dev who THINKS they are an expert.  So… I’ve compiled a small reality check for you SharePoint Devs. and a “red flag” check for those of you wishing to hire a SharePoint developer. If any of these apply to you, you are probably not a SharePoint Development Expert. You are not a SharePoint Development Expert if you manually copy your DLLs Seriously, I don’t care if you write the best code in the world. If you are manually copying files to each web front end you are NOT a SharePoint Development expert. Yes, I realize the admins are generally the ones who do the actual deployments, but if you don’t know how to create solution packages for your admins, you are going to end up doing more damage than good some day. There are TONS of tools out there to help generate deployable solutions for you. You have ZERO excuse. You are not a SharePoint Development expert if you can’t tell me the main artifacts of a solution package Directly related to the first one. If you don’t know what the Manifest, DDF, WSP, and Feature files are and how they are used in a solution package, you are NOT a SharePoint development expert. I’m not asking you to be able to write them all from scratch (heck, I can’t even do that), but you MUST know what they are and how to tweak them if necessary. You are not a SharePoint Development expert if you don’t know what a Content Type or a Site Column is You would be absolutely amazed at how many “Expert” SharePoint Developers have NEVER EVER created a Content Type or Site Column or even know what they are. I mean, why would you ever want to create those when you can just do everything as a custom list or custom field? right???? (that’s sarcasm). You also need to know how to package a Content Type and a Site Column into a deployable package by the way. You are not a SharePoint Development expert if you have not created at least one Web Part, Workflow, Timer Job, and Event Handler. If you haven’t written at least one of each, you don’t fully understand what they do or their limitations. Again, I expect NO ONE to be able to write these things blind. I think the last time I wrote an application from scratch without copying and pasting from another project I had done before was back in 1994? Seriously, coding is like a Sour Dough starter, you get it from someone else and keep adding to it. You are not a SharePoint Development expert if you don’t know how to properly dispose of objects Another biggie with zero excuse for getting it wrong. It is so well known that you must dispose of your SPWeb and SPSite objects that if you aren’t doing it then you are not an expert. Heck, if you utilize “using” when handling SPWeb and SPSite objects and don’t realize that it disposes of those objects for you, then you are not a SharePoint Development expert. You are not a SharePoint Development expert if you do not know how to properly elevate privileges Just one of those development basics that any decent SharePoint Developer has got to have down and understand how and why it’s used You are not a SharePoint Development expert if you don’t know all of the development options available to SharePoint and when they should be used Okay… so all you hard core .NET SharePoint dev geeks take a moment to listen. You may be the most top not SharePoint .NET developer in the world, but if you are opening Visual Studio to solve every problem in SharePoint, then you are NOT a SharePoint development expert. The SharePoint developer’s tool kit is growing every day with tools like Visual Studio, Data View Web Parts, XSL, jQuery, SPServices, etc. etc… If you don’t have the ability to at least recognize that “hey, you can basically do the same thing here but just dropping in Easy Tabs instead of writing some weird web part” then you are NOT a SharePoint Development expert AND you are doing a huge disservice to your clients and customers. You are probably NOT a SharePoint Development expert if you call yourself an Expert So, truth telling time. I’m not an expert. There, I said it. I feel so much better. Now, I realize the word “expert” has been used with my name before, but I am quick to point out that I KNOW the experts and know that they will help me if I need it, but I’m not an expert in all things SharePoint. The minute you take on that moniker you are setting yourself up for a fall. It’s too big, there’s too much to know, and there’s WAY too much you can do wrong. You are not a SharePoint Development expert if you are not involved in the community I expect to get the most flack for this one, but it’s always a huge red flag for me when someone says they are an expert and has ZERO knowledge of the SharePoint community. The SharePoint community is ABSOLUTELY CRITICAL to be an effective SharePoint developer, admin, architect, power user or whatever the heck you are!! The community keeps you sane, tells you when you are NOT using a best practice, recommends the best practice, and even knows when Microsoft is giving you the wrong information (*gasp* it does happen). If you can’t tell me who you are following on twitter, who's blog you read, what conferences you attend, or name the experts who you monitor to make sure you are not doing something stupid, then you are probably doing something stupid. Again, not asking you to be a speaker, blogger, or the least bit extroverted but you should be at LEAST stalking the experts. So… what’s the point? So… yeah… what’s my point in all this. Well, first of all let me point out that this is by far not a finished list and I could come up with a LOT more specific “deep dive” questions, but these should be high enough level that even non experts can recognize and ask them. If you have some common ones you run into let me know and add them in the comments below. Also, keep in mind I’m not saying you as a developer HAVE to know EVERYTHING, but you DO need to know what you don’t know and proudly and honestly state “I don’t know, but I’ll learn and find out”.  Those of us hiring SharePoint developers and know and have a passion for SharePoint are not looking for that elusive “expert” who knows everything. We are looking for someone who “gets it”, has a similar passion, great attitude, an understanding that they DON’T know everything, and a desire to do it right.  I would bet money that most SharePoint development disasters happen because of “experts” who think they know everything rather than the developer who is cautious and knows he doesn’t. Lastly, I know there’s a raging debate over what a “SharePoint Developer” is (I should know, as I keep bringing it up). So, obviously this blog post is more closely tied to the .NET side of SharePoint development and less towards the client side, middle tier, or whatever you want to call it. So, let’s please not get that argument going here as well…  Thanks

• Now Available &ndash; Windows Azure SDK 1.6

  - by Shaun

  Microsoft has just announced the Windows Azure SDK 1.6 and the Windows Azure Tools for Visual Studio 1.6. Now people can download the latest product through the WebPI. After you downloaded and installed the SDK you will find that The SDK 1.6 can be stayed side by side with the SDK 1.5, which means you can still using the 1.5 assemblies. But the Visual Studio Tools would be upgraded to 1.6. Different from the previous SDK, in this version it includes 4 components: Windows Azure Authoring Tools, Windows Azure Emulators, Windows Azure Libraries for .NET 1.6 and the Windows Azure Tools for Microsoft Visual Studio 2010. There are some significant upgrades in this version, which are Publishing Enhancement: More easily connect to the Windows Azure when publish your application by retrieving a publish setting file. It will let you configure some settings of the deployment, without getting back to the developer portal. Multi-profiles: The publish settings, cloud configuration files, etc. will be stored in one or more MSBuild files. It will be much easier to switch the settings between vary build environments. MSBuild Command-line Build Support. In-Place Upgrade Support.   Publishing Enhancement So let’s have a look about the new features of the publishing. Just create a new Windows Azure project in Visual Studio 2010 with a MVC 3 Web Role, and right-click the Windows Azure project node in the solution explorer, then select Publish, we will find the new publish dialog. In this version the first thing we need to do is to connect to our Windows Azure subscription. Click the “Sign in to download credentials” link, we will be navigated to the login page to provide the Live ID. The Windows Azure Tool will generate a certificate file and uploaded to the subscriptions those belong to us. Then we will download a PUBLISHSETTINGS file, which contains the credentials and subscriptions information. The Visual Studio Tool will generate a certificate and deployed to the subscriptions you have as the Management Certificate. The VS Tool will use this certificate to connect to the subscription in the next step. In the next step, I would back to the Visual Studio (the publish dialog should be stilling opened) and click the Import button, select the PUBLISHSETTINGS file I had just downloaded. Then all my subscriptions will be shown in the dropdown list. Select a subscription that I want the application to be published and press the Next button, then we can select the hosted service, environment, build configuration and service configuration shown in the dialog. In this version we can create a new hosted service directly here rather than go back to the developer portal. Just select the <Create New …> item in the hosted service. What we need to do is to provide the hosted service name and the location. Once clicked the OK, after several seconds the hosted service will be established. If we went to the developer portal we will find the new hosted service in my subscription. a) Currently we cannot select the Affinity Group when create a new hosted service through the Visual Studio Publish dialog. b) Although we can specify the hosted service name and DNS prefixing through the developer portal, we cannot do so from the VS Tool, which means the DNS prefixing would be the same as what we specified for the hosted service name. For example, we specified our hosted service name as “Sdk16Demo”, so the public URL would be http://sdk16demo.cloudapp.net/. After created a new hosted service we can select the cloud environment (production or staging), the build configuration (release or debug), and the service configuration (cloud or local). And we can set the Remote Desktop by check the related checkbox as well. One thing should be note is that, in this version when we set the Remote Desktop settings we don’t need to specify a certificate by default. This is because the Visual Studio will generate a new certificate for us by default. But we can still specify an existing certificate for RDC, by clicking the “More Options” button. Visual Studio Tool will create another certificate for the Remote Desktop connection. It will NOT use the certificate that managing the subscription. We also can select the “Advanced Settings” page to specify the deployment label, storage account, IntelliTrace and .NET profiling information, etc.. Press Next button, the dialog will display all settings I had just specified and it will save them as a new profile. The last step is to click the Publish button. Since we enabled the Remote Desktop feature, the first step of publishing was uploading the certificate. And then it will verify the storage account we specified and upload the package, then finally created the website in Windows Azure.   Multi-Profiles After published, if we back to the Visual Studio we can find a AZUREPUBXML file under the Profiles folder in the Azure project. It includes all settings we specified before. If we publish this project again, we can just use the current settings (hosted service, environment, RDC, etc.) from this profile without input them again. And this is very useful when we have more than one deployment settings. For example it would be able to have one AZUREPUBXML profile for deploying to testing environment (debug building, less roles with RDC and IntelliTrace) and one for production (release building, more roles but without IntelliTrace).   In-Place Upgrade Support Let’s change some codes in the MVC pages and click the Publish menu from the azure project node. No need to specify any settings,  here we can use the pervious settings by loading the azure profile file (AZUREPUBXML). After clicked the Publish button the VS Tool brought a dialog to us to indicate that there’s a deployment available in the hosted service environment, and prompt to REPLACE it or not. Notice that in this version, the dialog tool said “replace” rather than “delete”, which means by default the VS Tool will use In-Place Upgrade when we deploy to a hosted service that has a deployment already exist. After click Yes the VS Tool will upload the package and perform the In-Place Upgrade. If we back to the developer portal we can find that the status of the hosted service was turned to “Updating…”. But in the previous SDK, it will try to delete the whole deployment and publish a new one.   Summary When the Microsoft announced the features that allows the changing VM size via In-Place Upgrade, they also mentioned that in the next few versions the user experience of publishing the azure application would be improved. The target was trying to accomplish the whole publish experience in Visual Studio, which means no need to touch developer portal any more. In the SDK 1.6 we can see from the new publish dialog, as a developer we can do the whole process, includes creating hosted service, specifying the environment, configuration, remote desktop, etc. values without going back the the developer portal.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Changing an HTML Form's Target with jQuery

  - by Rick Strahl

  This is a question that comes up quite frequently: I have a form with several submit or link buttons and one or more of the buttons needs to open a new Window. How do I get several buttons to all post to the right window? If you're building ASP.NET forms you probably know that by default the Web Forms engine sends button clicks back to the server as a POST operation. A server form has a <form> tag which expands to this: <form method="post" action="default.aspx" id="form1"> Now you CAN change the target of the form and point it to a different window or frame, but the problem with that is that it still affects ALL submissions of the current form. If you multiple buttons/links and they need to go to different target windows/frames you can't do it easily through the <form runat="server"> tag. Although this discussion uses ASP.NET WebForms as an example, realistically this is a general HTML problem although likely more common in WebForms due to the single form metaphor it uses. In ASP.NET MVC for example you'd have more options by breaking out each button into separate forms with its own distinct target tag. However, even with that option it's not always possible to break up forms - for example if multiple targets are required but all targets require the same form data to the be posted. A common scenario here is that you might have a button (or link) that you click where you still want some server code to fire but at the end of the request you actually want to display the content in a new window. A common operation where this happens is report generation: You click a button and the server generates a report say in PDF format and you then want to display the PDF result in a new window without killing the content in the current window. Assuming you have other buttons on the same Page that need to post to base window how do you get the button click to go to a new window? Can't  you just use a LinkButton or other Link Control? At first glance you might think an easy way to do this is to use an ASP.NET LinkButton to do this - after all a LinkButton creates a hyper link that CAN accept a target and it also posts back to the server, right? However, there's no Target property, although you can set the target HTML attribute easily enough. Code like this looks reasonable: <asp:LinkButton runat="server" ID="btnNewTarget" Text="New Target" target="_blank" OnClick="bnNewTarget_Click" /> But if you try this you'll find that it doesn't work. Why? Because ASP.NET creates postbacks with JavaScript code that operates on the current window/frame: <a id="btnNewTarget" target="_blank" href="javascript:__doPostBack(&#39;btnNewTarget&#39;,&#39;&#39;)">New Target</a> What happens with a target tag is that before the JavaScript actually executes a new window is opened and the focus shifts to the new window. The new window of course is empty and has no __doPostBack() function nor access to the old document. So when you click the link a new window opens but the window remains blank without content - no server postback actually occurs. Natch that idea. Setting the Form Target for a Button Control or LinkButton So, in order to send Postback link controls and buttons to another window/frame, both require that the target of the form gets changed dynamically when the button or link is clicked. Luckily this is rather easy to do however using a little bit of script code and jQuery. Imagine you have two buttons like this that should go to another window: <asp:LinkButton runat="server" ID="btnNewTarget" Text="New Target" OnClick="ClickHandler" /> <asp:Button runat="server" ID="btnButtonNewTarget" Text="New Target Button" OnClick="ClickHandler" /> ClickHandler in this case is any routine that generates the output you want to display in the new window. Generally this output will not come from the current page markup but is generated externally - like a PDF report or some report generated by another application component or tool. The output generally will be either generated by hand or something that was generated to disk to be displayed with Response.Redirect() or Response.TransmitFile() etc. Here's the dummy handler that just generates some HTML by hand and displays it: protected void ClickHandler(object sender, EventArgs e) { // Perform some operation that generates HTML or Redirects somewhere else Response.Write("Some custom output would be generated here (PDF, non-Page HTML etc.)"); // Make sure this response doesn't display the page content // Call Response.End() or Response.Redirect() Response.End(); } To route this oh so sophisticated output to an alternate window for both the LinkButton and Button Controls, you can use the following simple script code: <script type="text/javascript"> $("#btnButtonNewTarget,#btnNewTarget").click(function () { $("form").attr("target", "_blank"); }); </script> So why does this work where the target attribute did not? The difference here is that the script fires BEFORE the target is changed to the new window. When you put a target attribute on a link or form the target is changed as the very first thing before the link actually executes. IOW, the link literally executes in the new window when it's done this way. By attaching a click handler, though we're not navigating yet so all the operations the script code performs (ie. __doPostBack()) and the collection of Form variables to post to the server all occurs in the current page. By changing the target from within script code the target change fires as part of the form submission process which means it runs in the correct context of the current page. IOW - the input for the POST is from the current page, but the output is routed to a new window/frame. Just what we want in this scenario. Voila you can dynamically route output to the appropriate window.© Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  HTML  jQuery

• Writing Unit Tests for an ASP.NET MVC Action Method that handles Ajax Request and Normal Request

  - by shiju

  In this blog post, I will demonstrate how to write unit tests for an ASP.NET MVC action method, which handles both Ajax request and normal HTTP Request. I will write a unit test for specifying the behavior of an Ajax request and will write another unit test for specifying the behavior of a normal HTTP request. Both Ajax request and normal request will be handled by a single action method. So the ASP.NET MVC action method will be execute HTTP Request object’s IsAjaxRequest method for identifying whether it is an Ajax request or not. So we have to create mock object for Request object and also have to make as a Ajax request from the unit test for verifying the behavior of an Ajax request. I have used NUnit and Moq for writing unit tests. Let me write a unit test for a Ajax request Code Snippet [Test] public void Index_AjaxRequest_Returns_Partial_With_Expense_List() {     // Arrange       Mock<HttpRequestBase> request = new Mock<HttpRequestBase>();     Mock<HttpResponseBase> response = new Mock<HttpResponseBase>();     Mock<HttpContextBase> context = new Mock<HttpContextBase>();       context.Setup(c => c.Request).Returns(request.Object);     context.Setup(c => c.Response).Returns(response.Object);     //Add XMLHttpRequest request header     request.Setup(req => req["X-Requested-With"]).         Returns("XMLHttpRequest");       IEnumerable<Expense> fakeExpenses = GetMockExpenses();     expenseRepository.Setup(x => x.GetMany(It.         IsAny<Expression<Func<Expense, bool>>>())).         Returns(fakeExpenses);     ExpenseController controller = new ExpenseController(         commandBus.Object, categoryRepository.Object,         expenseRepository.Object);     controller.ControllerContext = new ControllerContext(         context.Object, new RouteData(), controller);     // Act     var result = controller.Index(null, null) as PartialViewResult;     // Assert     Assert.AreEqual("_ExpenseList", result.ViewName);     Assert.IsNotNull(result, "View Result is null");     Assert.IsInstanceOf(typeof(IEnumerable<Expense>),             result.ViewData.Model, "Wrong View Model");     var expenses = result.ViewData.Model as IEnumerable<Expense>;     Assert.AreEqual(3, expenses.Count(),         "Got wrong number of Categories");         }   In the above unit test, we are calling Index action method of a controller named ExpenseController, which will returns a PartialView named _ExpenseList, if it is an Ajax request. We have created mock object for HTTPContextBase and setup XMLHttpRequest request header for Request object’s X-Requested-With for making it as a Ajax request. We have specified the ControllerContext property of the controller with mocked object HTTPContextBase. Code Snippet controller.ControllerContext = new ControllerContext(         context.Object, new RouteData(), controller); Let me write a unit test for a normal HTTP method Code Snippet [Test] public void Index_NormalRequest_Returns_Index_With_Expense_List() {     // Arrange               Mock<HttpRequestBase> request = new Mock<HttpRequestBase>();     Mock<HttpResponseBase> response = new Mock<HttpResponseBase>();     Mock<HttpContextBase> context = new Mock<HttpContextBase>();       context.Setup(c => c.Request).Returns(request.Object);     context.Setup(c => c.Response).Returns(response.Object);       IEnumerable<Expense> fakeExpenses = GetMockExpenses();       expenseRepository.Setup(x => x.GetMany(It.         IsAny<Expression<Func<Expense, bool>>>())).         Returns(fakeExpenses);     ExpenseController controller = new ExpenseController(         commandBus.Object, categoryRepository.Object,         expenseRepository.Object);     controller.ControllerContext = new ControllerContext(         context.Object, new RouteData(), controller);     // Act     var result = controller.Index(null, null) as ViewResult;     // Assert     Assert.AreEqual("Index", result.ViewName);     Assert.IsNotNull(result, "View Result is null");     Assert.IsInstanceOf(typeof(IEnumerable<Expense>),             result.ViewData.Model, "Wrong View Model");     var expenses = result.ViewData.Model         as IEnumerable<Expense>;     Assert.AreEqual(3, expenses.Count(),         "Got wrong number of Categories"); }   In the above unit test, we are not specifying the XMLHttpRequest request header for Request object’s X-Requested-With, so that it will be normal HTTP Request. If this is a normal request, the action method will return a ViewResult with a view template named Index. The below is the implementation of Index action method Code Snippet public ActionResult Index(DateTime? startDate, DateTime? endDate) {     //If date is not passed, take current month's first and last date     DateTime dtNow;     dtNow = DateTime.Today;     if (!startDate.HasValue)     {         startDate = new DateTime(dtNow.Year, dtNow.Month, 1);         endDate = startDate.Value.AddMonths(1).AddDays(-1);     }     //take last date of start date's month, if end date is not passed     if (startDate.HasValue && !endDate.HasValue)     {         endDate = (new DateTime(startDate.Value.Year,             startDate.Value.Month, 1)).AddMonths(1).AddDays(-1);     }     var expenses = expenseRepository.GetMany(         exp => exp.Date >= startDate && exp.Date <= endDate);     //if request is Ajax will return partial view     if (Request.IsAjaxRequest())     {         return PartialView("_ExpenseList", expenses);     }     //set start date and end date to ViewBag dictionary     ViewBag.StartDate = startDate.Value.ToShortDateString();     ViewBag.EndDate = endDate.Value.ToShortDateString();     //if request is not ajax     return View("Index",expenses); }   The index action method will returns a PartialView named _ExpenseList, if it is an Ajax request and will returns a View named Index if it is a normal request.

• RiverTrail - JavaScript GPPGU Data Parallelism

  - by JoshReuben

  Where is WebCL ? The Khronos WebCL working group is working on a JavaScript binding to the OpenCL standard so that HTML 5 compliant browsers can host GPGPU web apps – e.g. for image processing or physics for WebGL games - http://www.khronos.org/webcl/ . While Nokia & Samsung have some protype WebCL APIs, Intel has one-upped them with a higher level of abstraction: RiverTrail. Intro to RiverTrail Intel Labs JavaScript RiverTrail provides GPU accelerated SIMD data-parallelism in web applications via a familiar JavaScript programming paradigm. It extends JavaScript with simple deterministic data-parallel constructs that are translated at runtime into a low-level hardware abstraction layer. With its high-level JS API, programmers do not have to learn a new language or explicitly manage threads, orchestrate shared data synchronization or scheduling. It has been proposed as a draft specification to ECMA a (known as ECMA strawman). RiverTrail runs in all popular browsers (except I.E. of course). To get started, download a prebuilt version https://github.com/downloads/RiverTrail/RiverTrail/rivertrail-0.17.xpi , install Intel's OpenCL SDK http://www.intel.com/go/opencl and try out the interactive River Trail shell http://rivertrail.github.com/interactive For a video overview, see  http://www.youtube.com/watch?v=jueg6zB5XaM . ParallelArray the ParallelArray type is the central component of this API & is a JS object that contains ordered collections of scalars – i.e. multidimensional uniform arrays. A shape property describes the dimensionality and size– e.g. a 2D RGBA image will have shape [height, width, 4]. ParallelArrays are immutable & fluent – they are manipulated by invoking methods on them which produce new ParallelArray objects. ParallelArray supports several constructors over arrays, functions & even the canvas. // Create an empty Parallel Array var pa = new ParallelArray(); // pa0 = <>   // Create a ParallelArray out of a nested JS array. // Note that the inner arrays are also ParallelArrays var pa = new ParallelArray([ [0,1], [2,3], [4,5] ]); // pa1 = <<0,1>, <2,3>, <4.5>>   // Create a two-dimensional ParallelArray with shape [3, 2] using the comprehension constructor var pa = new ParallelArray([3, 2], function(iv){return iv[0] * iv[1];}); // pa7 = <<0,0>, <0,1>, <0,2>>   // Create a ParallelArray from canvas.  This creates a PA with shape [w, h, 4], var pa = new ParallelArray(canvas); // pa8 = CanvasPixelArray   ParallelArray exposes fluent API functions that take an elemental JS function for data manipulation: map, combine, scan, filter, and scatter that return a new ParallelArray. Other functions are scalar - reduce  returns a scalar value & get returns the value located at a given index. The onus is on the developer to ensure that the elemental function does not defeat data parallelization optimization (avoid global var manipulation, recursion). For reduce & scan, order is not guaranteed - the onus is on the dev to provide an elemental function that is commutative and associative so that scan will be deterministic – E.g. Sum is associative, but Avg is not. map Applies a provided elemental function to each element of the source array and stores the result in the corresponding position in the result array. The map method is shape preserving & index free - can not inspect neighboring values. // Adding one to each element. var source = new ParallelArray([1,2,3,4,5]); var plusOne = source.map(function inc(v) {     return v+1; }); //<2,3,4,5,6> combine Combine is similar to map, except an index is provided. This allows elemental functions to access elements from the source array relative to the one at the current index position. While the map method operates on the outermost dimension only, combine, can choose how deep to traverse - it provides a depth argument to specify the number of dimensions it iterates over. The elemental function of combine accesses the source array & the current index within it - element is computed by calling the get method of the source ParallelArray object with index i as argument. It requires more code but is more expressive. var source = new ParallelArray([1,2,3,4,5]); var plusOne = source.combine(function inc(i) { return this.get(i)+1; }); reduce reduces the elements from an array to a single scalar result – e.g. Sum. // Calculate the sum of the elements var source = new ParallelArray([1,2,3,4,5]); var sum = source.reduce(function plus(a,b) { return a+b; }); scan Like reduce, but stores the intermediate results – return a ParallelArray whose ith elements is the results of using the elemental function to reduce the elements between 0 and I in the original ParallelArray. // do a partial sum var source = new ParallelArray([1,2,3,4,5]); var psum = source.scan(function plus(a,b) { return a+b; }); //<1, 3, 6, 10, 15> scatter a reordering function - specify for a certain source index where it should be stored in the result array. An optional conflict function can prevent an exception if two source values are assigned the same position of the result: var source = new ParallelArray([1,2,3,4,5]); var reorder = source.scatter([4,0,3,1,2]); // <2, 4, 5, 3, 1> // if there is a conflict use the max. use 33 as a default value. var reorder = source.scatter([4,0,3,4,2], 33, function max(a, b) {return a>b?a:b; }); //<2, 33, 5, 3, 4> filter // filter out values that are not even var source = new ParallelArray([1,2,3,4,5]); var even = source.filter(function even(iv) { return (this.get(iv) % 2) == 0; }); // <2,4> Flatten used to collapse the outer dimensions of an array into a single dimension. pa = new ParallelArray([ [1,2], [3,4] ]); // <<1,2>,<3,4>> pa.flatten(); // <1,2,3,4> Partition used to restore the original shape of the array. var pa = new ParallelArray([1,2,3,4]); // <1,2,3,4> pa.partition(2); // <<1,2>,<3,4>> Get return value found at the indices or undefined if no such value exists. var pa = new ParallelArray([0,1,2,3,4], [10,11,12,13,14], [20,21,22,23,24]) pa.get([1,1]); // 11 pa.get([1]); // <10,11,12,13,14>

• Load balancing with multiple gateways

  - by ttouch

  I have to different ISPs, each on each own network. The main connects via ethernet and the secondary via wifi. The two networks have no relation at all. I just connect to them simultaneously. The reason I want to load balance between them is to achieve higher Internet speeds. Note: I have no advanced network hardware.

• Error when creating a new entity foo, editing a previously existing foo, then saving. Generic 4004 e

  - by Tarks

  The steps are as simple as that so I imagine there's something else going on here, the problem is I just get back 4004, no exception anywhere etc, making it annoying to debug, I get this from the ie error window Microsoft JScript runtime error: Unhandled Error in Silverlight Application Code: 4004 Category: ManagedRuntimeError Message: System.Windows.Ria.DomainOperationException: Submit operation failed.

• Best practice for structuring a new large ASP.NET MVC2 plus EF4 VS2010 solution?

  - by Nick

  Hi, we are building a new web application using Microsoft ASP.NET MVC2 and Entity Framework 4. Although I am sure there is not one right answer to my question, we are struggling to agree a VS2010 solution structure. The application will use SQL Server 2008 with a possible future Azure cloud version. We are using EF4 with T4 POCOs (model-first) and accessing a number of third-party web-services. We will also be connecting to a number of external messaging systems. UI is based on standard ASP.NET (MVC) with jQuery. In future we may deliver a Silverlight/WPF version - as well as mobile. So put simply, we start with a VS2010 blank solution - then what? I have suggested 4 folders Data (the EF edmx file etc), Domain (entities, repositories), Services (web-services access), Presentation (web ui etc). However under Presentation, creating the ASP.NET MVC2 project obviously creates it's own Models folder etc and it just doesn't seem to fit too well in this proposed structure. I'm also missing a business layer (or does this sit in the domain?). Again I am sure there is no one right way to do it, but I'd really appreciate your views on this. Thanks

• Problem in IE8 with GET Parameters in opening a new windows with javascript.

  - by amfa95

  Hi, I have a problem with IE8 and the opening of a new window with javascript and submitting parameters with special characters. <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question&#61;Wie hei&#223;t Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> The Problem is the letter 'ß' (sharp S). As you can see the string above is encodes due to anti XSS. This link works in FF and IE6 but IE8 is transmitting the URL Parameter as character with code 65*** (don't know the exaxt value). In the opening window you will only see a square (because character with 65000+ is not printable). I also tried to use URL Encoding instead of HTML encoding <a href="javascript:oWin('/html/de/4664286/printregistrationcontent.html?12-security question%3DWie hei%C3%9Ft Ihr Lieblingsrestaurant','PRINT',800,600);" class="print">Seite drucken</a> If i click on this Link in FF or IE6 it works as expected, but IE8 will fail to transmit the "ß" to the server and therefor will also get it back in the wrong way. If i paste this url to the IE8 it will work too, but not if the window is opened by javascript. The Javascript function oWin is defined as follows function oWin(url,title,sizeH,sizeV) { winHandle = top.open(url,title,'toolbar=no,directories=no,status=yes,scrollbars=yes,menubar=no,resizable=no,width='+sizeH+',height='+sizeV); if(navigator.appVersion.indexOf("MSIE 3",0)==-1) id = setTimeout('winHandle.focus()',1000); } If someone has an idea where to look for the reason please answer to this. Thank you amfa

• Simple way to decrease values without making a new attribute?

  - by Jam

  I'm making a program where you're firing a 'blaster', and I have 5 ammo. I'm blasting an alien who has 5 health. At the end I instantiate the player and make him blast 6 times to check that the program works correctly. But the way I've done it makes it so that the amount won't decrease. Is there an easy fix to this, or do I just have to make a new attribute for ammo and health? Here's what I have: class Player(object): """ A player in a shooter game. """ def blast(self, enemy, ammo=5): if ammo>=1: ammo-=1 print "You have blasted the alien." print "You have", ammo, "ammunition left." enemy.die(5) else: print "You are out of ammunition!" class Alien(object): """ An alien in a shooter game. """ def die(self, health=5): if health>=1: health-=1 print "The alien is wounded. He now has", health, "health left." elif health==0: health-=1 print "The alien gasps and says, 'Oh, this is it. This is the big one. \n" \ "Yes, it's getting dark now. Tell my 1.6 million larvae that I loved them... \n" \ "Good-bye, cruel universe.'" else: print "The alien's corpse sits up momentarily and says, 'No need to blast me, I'm dead already!" # main print "\t\tDeath of an Alien\n" hero = Player() invader = Alien() hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) raw_input("\n\nPress the enter key to exit.")

• Writing to a new window with javascript... get access denied

  - by Søren

  Hello gurus :) I have been struggling with this for a while now, and decided it was time to ask for help. I am trying to create a print function on an aspx page, and I am using javascript to do this: function PrintContentCell() { var display_setting = "toolbar=yes, location=no, directories=yes, menubar=yes,"; display_setting += "scrollbars=yes, width=750, height=600, left=100, top=25"; var content_innerhtml = document.getElementById("testTable").innerHTML; var document_print = window.open("Loading.htm", "", display_setting); document_print.document.open(); document_print.document.write('<html><head><title>Print</title></head>'); document_print.document.write('<body style="font-family:verdana; font-size:12px;" onLoad="self.print();self.close();" >'); document_print.document.write(content_innerhtml); document_print.document.write('</body></html>'); document_print.print(); document_print.document.close(); return false; } I get "Access Denied" when the script tries to write to the new window. The Loading.htm file is just a very slim html document writing out the text "Loading...". I had hoped this would work after reading this thread: http://stackoverflow.com/questions/735136/ie-6-7-access-denied-trying-to-access-a-popup-window-document Anybody can help?

• Is it possible for onunload confirm to open a new url in the same window?

  - by Dan Peschio

  Hi - this is my first post and I'm a JS novice, so please forgive my ignorance... Heres my question, its in two parts: 1.) At onunload I want an alert that asks the user if they would like to go to a related URL. The code I'm using works, but it open the URL in a new window and this can be blocked by a pop-up blocker even though the user has opted-in. Is there a way to have it open in the same window and negate the pop-up blocker? 2.) is there a way to take the onunload function out of the body tag and put it the script? Heres the code I'm using: <script language=javascript> function confirmit() { var closeit= confirm("Before you go would you like to add your press kit to the Search Press Kits database?"); if (closeit == true) {window.open("http://NEWURLHERE.com");} else {window.close();} } </script> </head> <body onunload="confirmit();"> peace </body> Thanks in advance, Dan
