• MIXing it Up a Bit

  - by andrewbrust

  Another March, another MIX.  For the fifth year running now, Microsoft has chosen to put on a conference aimed less at software development, per se, and more at the products, experiences and designs that software development can generate.  In all four prior MIX events, the focus of the show, its keynotes and breakout sessions has been on Web products.  On day 1 of MIX 2010 that focus shifted to Windows Phone 7 Series (WP7). What little we had seen of WP7 had been shown to us in a keynote presentation, given by Microsoft’s Joe Belfiore, at the Mobile World Congress in Barcelona, Spain last month.  And today, Mr. Belfiore reprised his showmanship for the MIX 2010 audience.  Joe showed us the ins and outs of WP7 and, in a breakout session, even gave us a sneak peek of Office (specifically, Excel) on WP7.  We didn’t get to see that one month ago in Barcelona, nor did get to see email messages opened for reading, which we saw today. But beyond a tour of the phone itself, impressive though that is, we got to see apps running on it.  Those apps included Associated Press news, Seesmic (a major Twitter client) and Foursquare (a social media darling).  All three ran, ran well, and looked markedly different and better from their corresponding versions on iPhone and Android.  And the games we saw looked even better. To me though, the best demos involved the creation of WP7 apps, using Silverlight in Visual Studio and Expression Blend.  These demos were so effective because they showed important apps being built in very few steps, and by Microsoft executives to boot.  Scott Guthrie showed us how to build a Twitter API app in Visual Strudio.   Jon Harris showed us how to build a photo management and viewer application in Expression Blend, using virtually no code.  Demos of apps built from scratch to F5 without the benefit of a teacher, could be challenging.  But they went off fine, without a hitch and without a ton of opaque, generated code.  Everything written, be it C# or XAML, was easily understood, and the results were impressive. That means lots of developers can do this, and I think it means a lot will.  What I’ve seen, thus far, of iPhone and Android development looks very tedious by comparison.  Development for those platforms involve a collection of tools that integrate only to a point.  Dev work for WP7 involves use of Visual Studio, Silverlight and the same debugging experience .NET developers already know.  This was very exciting for me. All the demos harkened back to days of building apps for with Visual Basic…design the front-end, put in code-behind and then hit F5.  And that makes sense, because the phone platform, and the PC of the early 90s are both, essentially, client OS machines.  The Web was minimal and the “device” was everything. Same is true of this phone.  It’s a client app contraption that fits in your pocket. And if the platforms are comparable, hopefully so too will be the draw of ease-of-development.   WP7 has the potential to make mobile developers want to switch over, and to convince enterprise developers to get into the phone scene.  Will this propel the new phone platform to new heights, and restore Microsoft’s competiveness in the mobile arena? I hope so.  I think so.  And if Microsoft uses developers to build themselves a victory, that would be beneficial and would show that Microsoft has learned from its failures, as well as its successes.  Today I saw a few beautiful apps.  Tomorrow I hope I see a slew of others; maybe not as polished, but plentiful, attractive and stable.  That would be a victory for Microsoft, and for developers.  And it would show everyone else that developers are the kingmakers.  They need cheap, efficient dev tools and lots of respect.  Microsoft has always been the company to provide that.  Hopefully, with WP7, they will return to that persona and see how very timeless it is.

• Representing Mauritius in the 2013 Bench Games

  Only by chance I came across an interesting option for professionals and enthusiasts in IT, and quite honestly I can't even remember where I caught attention of Brainbench and their 2013 Bench Games event. But having access to 600+ free exams in a friendly international intellectual competition doesn't happen to be available every day. So, it was actually a no-brainer to sign up and browse through the various categories. Most interestingly, Brainbench is not only IT-related. They offer a vast variety of fields in their Test Center, like Languages and Communication, Office Skills, Management, Aptitude, etc., and it can be a little bit messy about how things are organised. Anyway, while browsing through their test offers I added a couple of exams to 'My Plan' which I would give a shot afterwards. Self-assessments Actually, I took the tests based on two major aspects: 'Fun Factor' and 'How good would I be in general'... Usually, you have to pay for any kind of exams and given this unique chance by Brainbench to simply train this kind of tests was already worth the time. Frankly speaking, the tests are very close to the ones you would be asked to do at Prometric or Pearson Vue, ie. Microsoft exams, etc. Go through a set of multiple choice questions in a given time frame. Most of the tests I did during the Bench Games were based on 40 questions, each with a maximum of 3 minutes to answer. Ergo, one test in maximum 2 hours - that sounds feasible, doesn't it? The Measure of Achievement While the 2013 Bench Games are considered a worldwide friendly competition of knowledge I was really eager to get other Mauritians attracted. Using various social media networks and community activities it all looked quite well at the beginning. Mauritius was listed on rank #19 of Most Certified Citizens and rank #10 of Most Master Level Certified Nation - not bad, not bad... Until... the next update of the Bench Games Leaderboard. The downwards trend seemed to be unstoppable and I couldn't understand why my results didn't show up on the Individual Leader Board. First of all, I passed exams that were not even listed and second, I had better results on some exams listed. After some further information from the organiser it turned out that my test transcript wasn't available to the public. Only then results are considered and counted in the competition. During that time, I actually managed to hold 3 test results on the Individuals... Other participants were merciless, eh, more successful than me, produced better test results than I did. But still I managed to stay on the final score board: An 'exotic' combination of exam, test result, country and person itself Representing Mauritius and the Visual FoxPro community in that fun event. And although I mainly develop in Visual FoxPro 9.0 SP2 and C# using .NET Framework from 2.0 to 4.5 since a couple of years I still managed to pass on Master Level. Hm, actually my Microsoft Certified Programmer (MCP) exams are dated back in June 2004 - more than 9 years ago... Look who got lucky... As described above I did a couple of exams as time allowed and without any preparations, but still I received the following mail notification: "Thank you for recently participating in our Bench Games event.  We wanted to inform you that you obtained a top score on our test(s) during this event, and as a result, will receive a free annual Brainbench subscription.  Your annual subscription will give you access to all our tests just like Bench Games, but for an entire year plus additional benefits!" -- Leader Board Notification from Brainbench Even fun activities get rewarded sometimes. Thanks to @Brainbench_com for the free annual subscription based on my passed 2013 Bench Games Master Level exam. It would be interesting to know about the total figures, especially to see how many citizens of Mauritius took part in this year's Bench Games. Anyway, I'm looking forward to be able to participate in other challenges like this in the future.

• Different behavior for REF CURSOR between Oracle 10g and 11g when unique index present?

  - by wweicker

  Description I have an Oracle stored procedure that has been running for 7 or so years both locally on development instances and on multiple client test and production instances running Oracle 8, then 9, then 10, and recently 11. It has worked consistently until the upgrade to Oracle 11g. Basically, the procedure opens a reference cursor, updates a table then completes. In 10g the cursor will contain the expected results but in 11g the cursor will be empty. No DML or DDL changed after the upgrade to 11g. This behavior is consistent on every 10g or 11g instance I've tried (10.2.0.3, 10.2.0.4, 11.1.0.7, 11.2.0.1 - all running on Windows). The specific code is much more complicated but to explain the issue in somewhat realistic overview: I have some data in a header table and a bunch of child tables that will be output to PDF. The header table has a boolean (NUMBER(1) where 0 is false and 1 is true) column indicating whether that data has been processed yet. The view is limited to only show rows in that have not been processed (the view also joins on some other tables, makes some inline queries and function calls, etc). So at the time when the cursor is opened, the view shows one or more rows, then after the cursor is opened an update statement runs to flip the flag in the header table, a commit is issued, then the procedure completes. On 10g, the cursor opens, it contains the row, then the update statement flips the flag and running the procedure a second time would yield no data. On 11g, the cursor never contains the row, it's as if the cursor does not open until after the update statement runs. I'm concerned that something may have changed in 11g (hopefully a setting that can be configured) that might affect other procedures and other applications. What I'd like to know is whether anyone knows why the behavior is different between the two database versions and whether the issue can be resolved without code changes. Update 1: I managed to track the issue down to a unique constraint. It seems that when the unique constraint is present in 11g the issue is reproducible 100% of the time regardless of whether I'm running the real world code against the actual objects or the following simple example. Update 2: I was able to completely eliminate the view from the equation. I have updated the simple example to show the problem exists even when querying directly against the table. Simple Example CREATE TABLE tbl1 ( col1 VARCHAR2(10), col2 NUMBER(1) ); INSERT INTO tbl1 (col1, col2) VALUES ('TEST1', 0); /* View is no longer required to demonstrate the problem CREATE OR REPLACE VIEW vw1 (col1, col2) AS SELECT col1, col2 FROM tbl1 WHERE col2 = 0; */ CREATE OR REPLACE PACKAGE pkg1 AS TYPE refWEB_CURSOR IS REF CURSOR; PROCEDURE proc1 (crs OUT refWEB_CURSOR); END pkg1; CREATE OR REPLACE PACKAGE BODY pkg1 IS PROCEDURE proc1 (crs OUT refWEB_CURSOR) IS BEGIN OPEN crs FOR SELECT col1 FROM tbl1 WHERE col1 = 'TEST1' AND col2 = 0; UPDATE tbl1 SET col2 = 1 WHERE col1 = 'TEST1'; COMMIT; END proc1; END pkg1; Anonymous Block Demo DECLARE crs1 pkg1.refWEB_CURSOR; TYPE rectype1 IS RECORD ( col1 vw1.col1%TYPE ); rec1 rectype1; BEGIN pkg1.proc1 ( crs1 ); DBMS_OUTPUT.PUT_LINE('begin first test'); LOOP FETCH crs1 INTO rec1; EXIT WHEN crs1%NOTFOUND; DBMS_OUTPUT.PUT_LINE(rec1.col1); END LOOP; DBMS_OUTPUT.PUT_LINE('end first test'); END; /* After creating this index, the problem is seen */ CREATE UNIQUE INDEX unique_col1 ON tbl1 (col1); /* Reset data to initial values */ TRUNCATE TABLE tbl1; INSERT INTO tbl1 (col1, col2) VALUES ('TEST1', 0); DECLARE crs1 pkg1.refWEB_CURSOR; TYPE rectype1 IS RECORD ( col1 vw1.col1%TYPE ); rec1 rectype1; BEGIN pkg1.proc1 ( crs1 ); DBMS_OUTPUT.PUT_LINE('begin second test'); LOOP FETCH crs1 INTO rec1; EXIT WHEN crs1%NOTFOUND; DBMS_OUTPUT.PUT_LINE(rec1.col1); END LOOP; DBMS_OUTPUT.PUT_LINE('end second test'); END; Example of what the output on 10g would be:   begin first test   TEST1   end first test   begin second test   TEST1   end second test Example of what the output on 11g would be:   begin first test   TEST1   end first test   begin second test   end second test Clarification I can't remove the COMMIT because in the real world scenario the procedure is called from a web application. When the data provider on the front end calls the procedure it will issue an implicit COMMIT when disconnecting from the database anyways. So if I remove the COMMIT in the procedure then yes, the anonymous block demo would work but the real world scenario would not because the COMMIT would still happen. Question Why is 11g behaving differently? Is there anything I can do other than re-write the code?

• TFS 2010 SDK: Connecting to TFS 2010 Programmatically&ndash;Part 1

  - by Tarun Arora

  Technorati Tags: Team Foundation Server 2010,TFS 2010 SDK,TFS API,TFS Programming,TFS ALM   Download Working Demo Great! You have reached that point where you would like to extend TFS 2010. The first step is to connect to TFS programmatically. 1. Download TFS 2010 SDK => http://visualstudiogallery.msdn.microsoft.com/25622469-19d8-4959-8e5c-4025d1c9183d?SRC=VSIDE 2. Alternatively you can also download this from the visual studio extension manager 3. Create a new Windows Forms Application project and add reference to TFS Common and client dlls Note - If Microsoft.TeamFoundation.Client and Microsoft.TeamFoundation.Common do not appear on the .NET tab of the References dialog box, use the Browse tab to add the assemblies. You can find them at %ProgramFiles%\Microsoft Visual Studio 10.0\Common7\IDE\ReferenceAssemblies\v2.0. using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.Framework.Client; using Microsoft.TeamFoundation.Framework.Common;   4. There are several ways to connect to TFS, the two classes of interest are, Option 1 – Class – TfsTeamProjectCollectionClass namespace Microsoft.TeamFoundation.Client { public class TfsTeamProjectCollection : TfsConnection { public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection); public TfsTeamProjectCollection(Uri uri); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(Uri uri, ICredentials credentials); public TfsTeamProjectCollection(Uri uri, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(Uri uri, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public override CatalogNode CatalogNode { get; } public TfsConfigurationServer ConfigurationServer { get; internal set; } public override string Name { get; } public static Uri GetFullyQualifiedUriForName(string name); protected override object GetServiceInstance(Type serviceType, object serviceInstance); protected override object InitializeTeamFoundationObject(string fullName, object instance); } } Option 2 – Class – TfsConfigurationServer namespace Microsoft.TeamFoundation.Client { public class TfsConfigurationServer : TfsConnection { public TfsConfigurationServer(RegisteredConfigurationServer application); public TfsConfigurationServer(Uri uri); public TfsConfigurationServer(RegisteredConfigurationServer application, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(Uri uri, ICredentials credentials); public TfsConfigurationServer(Uri uri, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(Uri uri, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(RegisteredConfigurationServer application, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(RegisteredConfigurationServer application, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public override CatalogNode CatalogNode { get; } public override string Name { get; } protected override object GetServiceInstance(Type serviceType, object serviceInstance); public TfsTeamProjectCollection GetTeamProjectCollection(Guid collectionId); protected override object InitializeTeamFoundationObject(string fullName, object instance); } }   Note – The TeamFoundationServer class is obsolete. Use the TfsTeamProjectCollection or TfsConfigurationServer classes to talk to a 2010 Team Foundation Server. In order to talk to a 2005 or 2008 Team Foundation Server use the TfsTeamProjectCollection class. 5. Sample code for programmatically connecting to TFS 2010 using the TFS 2010 API How do i know what the URI of my TFS server is, Note – You need to be have Team Project Collection view details permission in order to connect, expect to receive an authorization failure message if you do not have sufficient permissions. Case 1: Connect by Uri string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri)); Case 2: Connect by Uri, prompt for credentials string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri), new UICredentialsProvider()); configurationServer.EnsureAuthenticated(); Case 3: Connect by Uri, custom credentials In order to use this method of connectivity you need to implement the interface ICredentailsProvider public class ConnectByImplementingCredentialsProvider : ICredentialsProvider { public ICredentials GetCredentials(Uri uri, ICredentials iCredentials) { return new NetworkCredential("UserName", "Password", "Domain"); } public void NotifyCredentialsAuthenticated(Uri uri) { throw new ApplicationException("Unable to authenticate"); } } And now consume the implementation of the interface, string _myUri = @"https://tfs.codeplex.com:443/tfs/tfs30"; ConnectByImplementingCredentialsProvider connect = new ConnectByImplementingCredentialsProvider(); ICredentials iCred = new NetworkCredential("UserName", "Password", "Domain"); connect.GetCredentials(new Uri(_myUri), iCred); TfsConfigurationServer configurationServer = TfsConfigurationServerFactory.GetConfigurationServer(new Uri(_myUri), connect); configurationServer.EnsureAuthenticated();   6. Programmatically query TFS 2010 using the TFS SDK for all Team Project Collections and retrieve all Team Projects and output the display name and description of each team project. CatalogNode catalogNode = configurationServer.CatalogNode; ReadOnlyCollection<CatalogNode> tpcNodes = catalogNode.QueryChildren( new Guid[] { CatalogResourceTypes.ProjectCollection }, false, CatalogQueryOptions.None); // tpc = Team Project Collection foreach (CatalogNode tpcNode in tpcNodes) { Guid tpcId = new Guid(tpcNode.Resource.Properties["InstanceId"]); TfsTeamProjectCollection tpc = configurationServer.GetTeamProjectCollection(tpcId); // Get catalog of tp = 'Team Projects' for the tpc = 'Team Project Collection' var tpNodes = tpcNode.QueryChildren( new Guid[] { CatalogResourceTypes.TeamProject }, false, CatalogQueryOptions.None); foreach (var p in tpNodes) { Debug.Write(Environment.NewLine + " Team Project : " + p.Resource.DisplayName + " - " + p.Resource.Description + Environment.NewLine); } }   Output   You can download a working demo that uses TFS SDK 2010 to programmatically connect to TFS 2010.

• Diagnose PC Hardware Problems with an Ubuntu Live CD

  - by Trevor Bekolay

  So your PC randomly shuts down or gives you the blue screen of death, but you can’t figure out what’s wrong. The problem could be bad memory or hardware related, and thankfully the Ubuntu Live CD has some tools to help you figure it out. Test your RAM with memtest86+ RAM problems are difficult to diagnose—they can range from annoying program crashes, or crippling reboot loops. Even if you’re not having problems, when you install new RAM it’s a good idea to thoroughly test it. The Ubuntu Live CD includes a tool called Memtest86+ that will do just that—test your computer’s RAM! Unlike many of the Live CD tools that we’ve looked at so far, Memtest86+ has to be run outside of a graphical Ubuntu session. Fortunately, it only takes a few keystrokes. Note: If you used UNetbootin to create an Ubuntu flash drive, then memtest86+ will not be available. We recommend using the Universal USB Installer from Pendrivelinux instead (persistence is possible with Universal USB Installer, but not mandatory). Boot up your computer with a Ubuntu Live CD or USB drive. You will be greeted with this screen: Use the down arrow key to select the Test memory option and hit Enter. Memtest86+ will immediately start testing your RAM. If you suspect that a certain part of memory is the problem, you can select certain portions of memory by pressing “c” and changing that option. You can also select specific tests to run. However, the default settings of Memtest86+ will exhaustively test your memory, so we recommend leaving the settings alone. Memtest86+ will run a variety of tests that can take some time to complete, so start it running before you go to bed to give it adequate time. Test your CPU with cpuburn Random shutdowns – especially when doing computationally intensive tasks – can be a sign of a faulty CPU, power supply, or cooling system. A utility called cpuburn can help you determine if one of these pieces of hardware is the problem. Note: cpuburn is designed to stress test your computer – it will run it fast and cause the CPU to heat up, which may exacerbate small problems that otherwise would be minor. It is a powerful diagnostic tool, but should be used with caution. Boot up your computer with a Ubuntu Live CD or USB drive, and choose to run Ubuntu from the CD or USB drive. When the desktop environment loads up, open the Synaptic Package Manager by clicking on the System menu in the top-left of the screen, then selecting Administration, and then Synaptic Package Manager. Cpuburn is in the universe repository. To enable the universe repository, click on Settings in the menu at the top, and then Repositories. Add a checkmark in the box labeled “Community-maintained Open Source software (universe)”. Click close. In the main Synaptic window, click the Reload button. After the package list has reloaded and the search index has been rebuilt, enter “cpuburn” in the Quick search text box. Click the checkbox in the left column, and select Mark for Installation. Click the Apply button near the top of the window. As cpuburn installs, it will caution you about the possible dangers of its use. Assuming you wish to take the risk (and if your computer is randomly restarting constantly, it’s probably worth it), open a terminal window by clicking on the Applications menu in the top-left of the screen and then selection Applications > Terminal. Cpuburn includes a number of tools to test different types of CPUs. If your CPU is more than six years old, see the full list; for modern AMD CPUs, use the terminal command burnK7 and for modern Intel processors, use the terminal command burnP6 Our processor is an Intel, so we ran burnP6. Once it started up, it immediately pushed the CPU up to 99.7% total usage, according to the Linux utility “top”. If your computer is having a CPU, power supply, or cooling problem, then your computer is likely to shutdown within ten or fifteen minutes. Because of the strain this program puts on your computer, we don’t recommend leaving it running overnight – if there’s a problem, it should crop up relatively quickly. Cpuburn’s tools, including burnP6, have no interface; once they start running, they will start driving your CPU until you stop them. To stop a program like burnP6, press Ctrl+C in the terminal window that is running the program. Conclusion The Ubuntu Live CD provides two great testing tools to diagnose a tricky computer problem, or to stress test a new computer. While they are advanced tools that should be used with caution, they’re extremely useful and easy enough that anyone can use them.

• Management and Monitoring Tools for Windows Azure

  - by BuckWoody

  With such a large platform, Windows Azure has a lot of moving parts. We’ve done our best to keep the interface as simple as possible, while giving you the most control and visibility we can. However, as with most Microsoft products, there are multiple ways to do something – and I’ve always found that to be a good strength. Depending on the situation, I might want a graphical interface, a command-line interface, or just an API so I can incorporate the management into my own tools, or have third-party companies write other tools. While by no means exhaustive, I thought I might put together a quick list of a few tools you can use to manage and monitor Windows Azure components, from our IaaS, SaaS and PaaS offerings. Some of the products focus on one area more than another, but all are available today. I’ll try and maintain this list to keep it current, but make sure you check the date of this post’s update – if it’s more than six months old, it’s most likely out of date. Things move fast in the cloud. The Windows Azure Management Portal The primary tool for managing Windows Azure is our portal – most everything you need is there, from creating new services to querying a database. There are two versions as of this writing – a Silverlight client version, and a newer HTML5 version. The latter is being updated constantly to be in parity with the Silverlight client. There’s a balance in this portal between simplicity and power – we’re following the “less is more” approach, with increasing levels of detail as you work through the portal rather than overwhelming you with a single, long “more is more” page. You can find the Portal here: http://windowsazure.com (then click “Log In” and then “Portal”) Windows Azure Management API You can also use programming tools to either write your own interface, or simply provide management functions directly within your solution. You have two options – you can use the more universal REST API’s, which area bit more complex but work with any system that can write to them, or the more approachable .NET API calls in code. You can find the reference for the API’s here: http://msdn.microsoft.com/en-us/library/windowsazure/ee460799.aspx  All Class Libraries, for each part of Windows Azure: http://msdn.microsoft.com/en-us/library/ee393295.aspx  PowerShell Command-lets PowerShell is one of the most powerful scripting languages I’ve used with Windows – and it’s baked into all of our products. When you need to work with multiple servers, scripting is really the only way to go, and the Windows Azure PowerShell Command-Lets allow you to work across most any part of the platform – and can even be used within the services themselves. You can do everything with them from creating a new IaaS, PaaS or SaaS service, to controlling them and even working with security and more. You can find more about the Command-Lets here: http://wappowershell.codeplex.com/documentation (older link, still works, will point you to the new ones as well) We have command-line utilities for other operating systems as well: https://www.windowsazure.com/en-us/manage/downloads/  Video walkthrough of using the Command-Lets: http://channel9.msdn.com/Events/BUILD/BUILD2011/SAC-859T  System Center System Center is actually a suite of graphical tools you can use to manage, deploy, control, monitor and tune software from Microsoft and even other platforms. This will be the primary tool we’ll recommend for managing a hybrid or contiguous management process – and as time goes on you’ll see more and more features put into System Center for the entire Windows Azure suite of products. You can find the Management Pack and README for it here: http://www.microsoft.com/en-us/download/details.aspx?id=11324  SQL Server Management Studio / Data Tools / Visual Studio SQL Server has two built-in management and development, and since Version 2008 R2, you can use them to manage Windows Azure Databases. Visual Studio also lets you connect to and manage portions of Windows Azure as well as Windows Azure Databases. You can read more about Visual Studio here: http://msdn.microsoft.com/en-us/library/windowsazure/ee405484  You can read more about the SQL tools here: http://msdn.microsoft.com/en-us/library/windowsazure/ee621784.aspx  Vendor-Provided Tools Microsoft does not suggest or endorse a specific third-party product. We do, however, use them, and see lots of other customers use them. You can browse to these sites to learn more, and chat with their folks directly on how they support Windows Azure.

Smaller projects have a way of coming and going, so I’ll try and make sure this list is current.

• Installing SharePoint 2013 on Windows 2012- standalone installation

  - by sreejukg

  In this article, I am going to share my experience while installing SharePoint 2013 on Windows 2012. This was the first time I tried SharePoint 2013. So I thought sharing the same will benefit somebody who would like to install SharePoint 2013 as a standalone installation. Standalone installation is meant for evaluation/development purposes. For production environments, you need to follow the best practices and create required service accounts. Microsoft has published the deployment guide for SharePoint 2013, you can download this from the below link. http://www.microsoft.com/en-us/download/details.aspx?id=30384 Since this is for development environment, I am not going to create any service account, I logged in to Windows 2012 as an administrator and just placed my installation DVD on the drive. When I run the setup from the DVD, the below splash screen appears. This reflects the new UI changes happening with all Microsoft based applications; the interface matches the metro style applications (Windows 8 style). As you can see the options are same as that of the SharePoint 2010 installation screen. Click on the “install software prerequisites” link to get all the prerequisites get installed. You need a valid internet connection to do this. Clicking on the install software prerequisites will bring the following dialog. Click Next, you will see the terms and conditions. Select I accept check box and click Next. The installation will start immediately. For any reason, if you stop the installation and start it later, the product preparation tool will check whether a particular component is installed and if yes, then the installation of that particular component will be skipped. If you do not have internet connection, you will face the download error as follows. At any point of failure, the error log will be available for you to review. If all OK, you will reach the below dialog, this means some components will be installed once the PC is rebooted. Be noted that the clicking on finish will not ask you for further confirmation. So make sure to save all your work before clicking on finish button. Once the server is restarted, the product preparation tool will start automatically and you will see the following dialog. Now go to the SharePoint 2013 splash page and click on “Install SharePoint Server” link. You need to enter the product key here. Enter the product key as you received and click continue. Select the Checkbox for the license agreement and click on continue button. Now you need to select the installation type. Select Stand-alone and click on “Install Now” button. A dialog will pop up that updates you with the process and progress. The installation took around 15-20 minutes with 2 GB or Ram installed in the server, seems fair. Once the installation is over, you will see the following Dialog. Make sure you select the Run the products and configuration wizard. If you miss to select the check box, you can find the products and configuration wizard from the start tiles. The products and configuration wizard will start. If you get any dialog saying some of the services will be stopped, you just accept it. Since we selected standalone installation, it will not ask for any user input, as it already knows the database to be configured. Once the configuration is over without any problems you will see the configuration successful message. Also you can find the link to central administration on the Start Screen.     Troubleshooting During my first setup process, I got the below error. System.ArgumentException: The SDDL string contains an invalid sid or a sid that cannot be translated. Parameter name: sddlForm at System.Security.AccessControl.RawSecurityDescriptor.BinaryFormFromSddlForm(String sddlForm) at System.Security.AccessControl.RawSecurityDescriptor..ctor(String sddlForm) at Microsoft.SharePoint.Win32.SPNetApi32.CreateShareSecurityDescriptor(String[] readNames, String[] changeNames, String[] fullControlNames, String& sddl) at Microsoft.SharePoint.Win32.SPNetApi32.CreateFileShare(String name, String description, String path) at Microsoft.SharePoint.Administration.SPServer.CreateFileShare(String name, String description, String path) at Microsoft.Office.Server.Search.Administration.AnalyticsAdministration.CreateAnalyticsUNCShare(String dirParentLocation, String shareName) at Microsoft.Office.Server.Search.Administration.AnalyticsAdministration.ProvisionAnalyticsShare(SearchServiceApplication serviceApplication) ………………………………………… ………………………………………… The configuration wizard displayed the error as below. The error occurred in step 8 of the configuration wizard and by the time the central administration is already provisioned. So from the start, I was able to open the central administration website, but the search service application was showing as error. I found a good blog that specifies the reason for error. http://kbdump.com/sharepoint2013-standalone-config-error-create-sample-data/ The workaround specified in the blog works fine. I think SharePoint must be provisioning Search using the Network Service account, so instead of giving permission to everyone, you could try giving permission to Network Service account(I didn’t try this yet, buy you could try and post your feedback here). In production environment you will have specific accounts that have access rights as recommended by Microsoft guidelines. Installation of SharePoint 2013 is pretty straight forward. Hope you enjoyed the article!

• Management and Monitoring Tools for Windows Azure

  - by BuckWoody

  With such a large platform, Windows Azure has a lot of moving parts. We’ve done our best to keep the interface as simple as possible, while giving you the most control and visibility we can. However, as with most Microsoft products, there are multiple ways to do something – and I’ve always found that to be a good strength. Depending on the situation, I might want a graphical interface, a command-line interface, or just an API so I can incorporate the management into my own tools, or have third-party companies write other tools. While by no means exhaustive, I thought I might put together a quick list of a few tools you can use to manage and monitor Windows Azure components, from our IaaS, SaaS and PaaS offerings. Some of the products focus on one area more than another, but all are available today. I’ll try and maintain this list to keep it current, but make sure you check the date of this post’s update – if it’s more than six months old, it’s most likely out of date. Things move fast in the cloud. The Windows Azure Management Portal The primary tool for managing Windows Azure is our portal – most everything you need is there, from creating new services to querying a database. There are two versions as of this writing – a Silverlight client version, and a newer HTML5 version. The latter is being updated constantly to be in parity with the Silverlight client. There’s a balance in this portal between simplicity and power – we’re following the “less is more” approach, with increasing levels of detail as you work through the portal rather than overwhelming you with a single, long “more is more” page. You can find the Portal here: http://windowsazure.com (then click “Log In” and then “Portal”) Windows Azure Management API You can also use programming tools to either write your own interface, or simply provide management functions directly within your solution. You have two options – you can use the more universal REST API’s, which area bit more complex but work with any system that can write to them, or the more approachable .NET API calls in code. You can find the reference for the API’s here: http://msdn.microsoft.com/en-us/library/windowsazure/ee460799.aspx  All Class Libraries, for each part of Windows Azure: http://msdn.microsoft.com/en-us/library/ee393295.aspx  PowerShell Command-lets PowerShell is one of the most powerful scripting languages I’ve used with Windows – and it’s baked into all of our products. When you need to work with multiple servers, scripting is really the only way to go, and the Windows Azure PowerShell Command-Lets allow you to work across most any part of the platform – and can even be used within the services themselves. You can do everything with them from creating a new IaaS, PaaS or SaaS service, to controlling them and even working with security and more. You can find more about the Command-Lets here: http://wappowershell.codeplex.com/documentation (older link, still works, will point you to the new ones as well) We have command-line utilities for other operating systems as well: https://www.windowsazure.com/en-us/manage/downloads/  Video walkthrough of using the Command-Lets: http://channel9.msdn.com/Events/BUILD/BUILD2011/SAC-859T  System Center System Center is actually a suite of graphical tools you can use to manage, deploy, control, monitor and tune software from Microsoft and even other platforms. This will be the primary tool we’ll recommend for managing a hybrid or contiguous management process – and as time goes on you’ll see more and more features put into System Center for the entire Windows Azure suite of products. You can find the Management Pack and README for it here: http://www.microsoft.com/en-us/download/details.aspx?id=11324  SQL Server Management Studio / Data Tools / Visual Studio SQL Server has two built-in management and development, and since Version 2008 R2, you can use them to manage Windows Azure Databases. Visual Studio also lets you connect to and manage portions of Windows Azure as well as Windows Azure Databases. You can read more about Visual Studio here: http://msdn.microsoft.com/en-us/library/windowsazure/ee405484  You can read more about the SQL tools here: http://msdn.microsoft.com/en-us/library/windowsazure/ee621784.aspx  Vendor-Provided Tools Microsoft does not suggest or endorse a specific third-party product. We do, however, use them, and see lots of other customers use them. You can browse to these sites to learn more, and chat with their folks directly on how they support Windows Azure.

• Adding a Network Loopback Adapter to Windows 8

  - by Greg Low

  I have to say that I continue to be frustrated with finding out how to do things in Windows 8. Here's another one and it's recorded so it might help someone else. I've also documented what I tried so that if anyone from the product group ever reads this, they'll understand how I searched for it and might try to make it easier.I wanted to add a network loopback adapter, to have a fixed IP address to work with when using an "internal" network with Hyper-V. (The fact that I even need to do this is also painful. I don't know why Hyper-V can't make it easy to work with host system folders, etc. as easily as I can with VirtualPC, VirtualBox, etc. but that's a topic for another day).In the end, what I needed was a known IP address on the same network that my guest OS was using, via the internal network (which allows connectivity from the host OS to/from guest OS's).I started by looking in the network adapters areas but there is no "add" functionality there. Realising that this was likely to be another unexpected challenge, I resorted to searching for info on doing this. I found KB article 2777200 entitled "Installing the Microsoft Loopback Adapter in Windows 8 and Windows Server 2012". Aha, I thought that's what I'd need. It describes the symptom as "You are trying to install the Microsoft Loopback Adapter, but are unable to find it." and that certainly sounded like me. There's a certain irony in documenting that something's hard to find instead of making it easier to find. Anyway, you'd hope that in that article, they'd then provide a step by step example of how to do it, but what they supply is this: The Microsoft Loopback Adapter was renamed in Windows 8 and Windows Server 2012. The new name is "Microsoft KM-TEST Loopback Adapter". When using the Add Hardware Wizard to manually add a network adapter, choose Manufacturer "Microsoft" and choose network adapter "Microsoft KM-TEST Loopback Adapter".The trick with this of course is finding the "Add Hardware Wizard". In Control Panel -> Hardware and Sound, there are options to "Add a device" and for "Device Manager". I tried the "Add a device" wizard (seemed logical to me) but after that wizard tries it's best, it just tells you that there isn't any hardware that it thinks it needs to install. It offers a link for when you can't find what you're looking for, but that leads to a generic help page that tells you how to do things like turning on your printer.In Device Manager, I checked the options in the program menus, and nothing useful was present. I even tried right-clicking "Network adapters", hoping that would lead to an option to add one, also to no avail.So back to the search engine I went, to try to find out where the "Add Hardware Wizard" is. Turns out I was in the right place in Device Manager, but I needed to right-click the computer's name, and choose "Add Legacy Hardware". No doubt that hasn't changed location lately but it's a while since I needed to add one so I'd forgotten. Regardless, I'm left wondering why it couldn't be in the menu as well.Anyway, for a step by step list, you need to do the following:1. From Control Panel, select "Device Manager" under the "Devices and Printers" section of the "Hardware and Sound" tab.2. Right-click the name of the computer at the top of the tree, and choose "Add Legacy Hardware".3. In the "Welcome to the Add Hardware Wizard" window, click Next.4. In the "The wizard can help you install other hardware" window, choose "Install the hardware that I manually select from a list" option and click Next.5. In the "The wizard did not find any new hardware on your computer" window, click Next.6. In the "From the list below, select the type of hardware you are installing" window, select "Network Adapters" from the list, and click Next.7. In the "Select Network Adapter" window, from the Manufacturer list, choose Microsoft, then in the Network Adapter window, choose "Microsoft KM-TEST Loopback Adapter", then click Next.8. In the "The wizard is ready to install your hardware" window, click Next.9. In the "Completing the Add Hardware Wizard" window, click Finish.Then you need to continue to set the IP address, etc.10. Back in Control Panel, select the "Network and Internet" tab, click "View Network Status and Tasks".11. In the "View your basic network information and set up connections" window, click "Change adapter settings".12. Right-click the new adapter that has been added (find it in the list by checking the device name of "Microsoft KM-TEST Loopback Adapter"), and click Properties.

• Build 2012, some thoughts..

  - by Dennis Vroegop

  I think you probably read my rant about the logistics at Build 2012, as posted here, so I am not going into that anymore. Instead, let’s look at the content. (BTW If you did read that post and want some more info then read Nia Angelina’s post about Build. I have nothing to add to that.) As usual, there were good speakers and some speakers who could benefit from some speaker training. I find it hard to understand why Microsoft allows certain people on stage, people who speak English with such strong accents it’s hard for people, especially from abroad, to understand. Some basic training might be useful for some of them. However, it is nice to see that most speakers are project managers, program managers or even devs on the teams that build the stuff they talk about: there was a lot of knowledge on stage! And that means when you ask questions you get very relevant information. I realize I am not the average audience member here, I am regular speaker myself so I tend to look for other things when I am in a room than most audience members so my opinion might differ from others. All in all the knowledge of the speakers was above average but the presentation skills were most of the times below what I would describe as adequate. But let us look at the contents. Since the official name of the conference is Build Windows 2012 it is not surprising most of the talks were focused on building Windows 8 apps. Next to that, there was a lot of focus on Azure and of course Windows Phone 8 that launched the day before Build started. Most sessions dealt with C# and JavaScript although I did see a tendency to use C++ more. Touch. Well, that was the focus on a lot of sessions, that goes without saying. Microsoft is really betting on Touch these days and being a Touch oriented developer I can only applaud this. The term NUI is getting a bit outdated but the principles behind it certainly aren’t. The sessions did cover quite a lot on how to make your applications easy to use and easy to understand. However, not all is touch nowadays; still the majority of people use keyboard and mouse to interact with their machines (or, as I do, use keyboard, mouse AND touch at the same time). Microsoft understands this and has spend some serious thoughts on this as well. It was all about making your apps run everywhere on all sorts of devices and in all sorts of scenarios. I have seen a couple of sessions focusing on the portable class library and on sharing code between Windows 8 and Windows Phone 8. You get the feeling Microsoft is enabling us devs to write software that will be ubiquitous. They want your stuff to be all over the place and they do anything they can to help. To achieve that goal they provide us with brilliant SDK’s, great tooling, a very, very good backend in the form of Windows Azure (I was particularly impressed by the Mobility part of Azure) and some fantastic hardware. And speaking of hardware: the partners such as Acer, Lenovo and Dell are making hardware that puts Apple to a shame nowadays. To illustrate: in Bellevue (very close to Redmond where Microsoft HQ is) they have the Microsoft Store located very close to the Apple Store, so it’s easy to compare devices. And I have to say: the Microsoft offerings are much, much more appealing that what the Cupertino guys have to offer. That was very visible by the number of people visiting the stores: even on the day that Apple launched the iPad Mini there were more people in the Microsoft store than in the Apple store. So, the future looks like it’s going to be fun. Great hardware (did I mention the Nokia Lumia 920? No? It’s brilliant), great software (Windows 8 is in a league of its own), the best dev tools (Visual Studio 2012 is still the champion here) and a fantastic backend (Azure.. need I say more?). It’s up to us devs to fill up the stores with applications that matches this. To summarize: it is great to be a Windows developer. PS. Did I mention Surface RT? Man….. People were drooling all over it wherever I went. It is fantastic :-) Technorati Tags: Build,Windows 8,Windows Phone,Lumia,Surface,Microsoft

• A Visual Studio Release Grows in Brooklyn

  - by andrewbrust

  Yesterday, Microsoft held its flagship launch event for Office 2010 in Manhattan.  Today, the Redmond software company is holding a local launch event for Visual Studio (VS) 2010, in Brooklyn.  How come information workers get the 212 treatment and developers are relegated to 718? Well, here’s the thing: the Brooklyn Marriott is actually a great place for an event, but you need some intimate knowledge of New York City to know that.  NBC’s Studio 8H, where the Office launch was held yesterday (and from where SNL is broadcast) is a pretty small venue, but you’d need some inside knowledge to recognize that.  Likewise, while Office 2010 is a product whose value is apparent.  Appreciating VS 2010’s value takes a bit more savvy.  Setting aside its year-based designation, this release of VS, counting the old Visual Basic releases, is the 10th version of the product.  How can a developer audience get excited about an integrated development environment when it reaches double-digit version numbers?  Well, it can be tough.  Luckily, Microsoft sent Jay Schmelzer, a Group Program Manager from the Visual Studio team in Redmond, to come tell the Brooklyn audience why they should be excited. Turns out there’s a lot of reasons.  Support fro SharePoint development is a big one.  In previous versions of VS, that support has been anemic, at best.  Shortage of SharePoint developers is a huge issue in the industry, and this should help.  There’s also built in support for Windows Azure (Microsoft’s cloud platform) and, through a download, support for the forthcoming Windows Phone 7 platform.  ASP.NET MVC, a “close-to-the-metal” Web development option that does away with the Web Forms abstraction layer, has a first-class presence in VS.  So too does jQuery, the Open Source environment that makes JavaScript development a breeze.  The jQuery support is so good that Microsoft now contributes to that Open Source project and offers IntelliSense support for it in the code editor. Speaking of the VS code editor, it now supports multi-monitor setups, zoom-in, and block selection.  If you’re not a developer, this may sound confusing and minute.  I’ll just say that for people who are developers these are little things that really contribute to productivity, and that translates into lower development costs. The really cool demo, though, was around Visual Studio 2010’s new debugging features.  This stuff is hard to showcase, but I believe it’s truly breakthrough technology: imagine being able to step backwards in time to see what might have caused a bug.  Cool?  Now imagine being able to do that, even if you weren’t the tester and weren’t present while the testing was being done.  Then imagine being able to see a video screen capture of what the tester was doing with your app when the bug occurred.  VS 2010 allows all that.  This could be the demise of the IWOMM (“it works on my machine”) syndrome. After the keynote, I asked Schmelzer if any of Microsoft’s competitors have debugging tools that come close to VS 2010’s.  His answer was an earnest “we don’t think so.”  If that’s true, that’s a big deal, and a huge advantage for developer teams who adopt it.  It will make software development much cheaper and more efficient.  Kind of like holding a launch event at the Brooklyn Marriott instead of 30 Rock in Manhattan! VS 2010 (version 10) and Office 2010 (version 14) aren’t the only new product versions Microsoft is releasing right now.  There’s also SQL Server 2008 R2 (version 10.5), Exchange 2010 (version 8, I believe), SharePoint 2010 (version 4) and, of course, Windows 7.  With so many new versions at such levels of maturity, I think it’s fair to say Microsoft has reached middle-age.  How does a company stave off a potential mid-life crisis, especially when with young Turks like Google coming along and competing so fiercely?  Hard to say.  But if focusing on core value, including value that’s hard to play into a sexy demo, is part oft the answer, then Microsoft’s doing OK.  And if some new tricks, like Windows Phone 7, can gain some traction, that might round things out nicely. Are the legacy products old tricks, or are they revised classics?  I honestly don’t know, because it’s the market’s prerogative to pass that judgement.  I can say this though: based on today’s show, I think Microsoft’s been doing its homework.

• SQL SERVER – FIX ERROR – Cannot connect to . Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452)

  - by pinaldave

  Just a day ago, I was doing small attempting to connect to my local SQL Server using IP 127.0.0.1. The IP is of my local machine and SQL Server is installed on the local box as well. However, whenever I try to connect to the server it gave me following strange error. Cannot connect to 127.0.0.1. Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452) The reason was indeed strange as I was trying to connect from local box to local box and it said my login was from an untrusted domain. As my system is not part of any domain, this was really confusing to me. Another thing was that I have been always able to connect always using 127.0.0.1 to SQL Server and this was a bit strange to me. I started to think what did I change since it  last time I connected to SQL Server. Suddenly I remembered that I had modified my computer’s host file for some other purpose. Solution: I opened my host file and immediately added entry like 127.0.0.1 localhost. Once I added it I was able to reconnect to SQL Server as usual. The location of the host file is C:\Windows\System32\drivers\etc. You will find file with the name hosts in it, make sure to open it with notepad. If you are part of a domain and your organization is using active directory, make sure that your account is added properly to active directory as well have proper security permissions to execute the task.

• An observation on .NET loops – foreach, for, while, do-while

  It’s very common that .NET programmers use “foreach” loop for iterating through collections. Following is my observation whilst I was testing simple scenario on loops. “for” loop is 30% faster than “foreach” and “while” loop is 50% faster than “foreach”. “do-while” is bit faster than “while”. Someone may feel that how does it make difference if I’m iterating only 1000 times in a loop. This test case is only for simple iteration. According to the "Data structure" concepts, best and worst cases are completely based on the data we provide to the algorithm. so we can not conclude that a "foreach" algorithm is not good. All I want to tell that we need to be little cautious even choosing the loops. Example:- You might want to chose quick sort when you want to sort more numbers. At the same time bubble sort may be effective than quick sort when you want to sort less numbers. Take a simple scenario, a request of a simple web application fetches the data of 10000 (10K) rows and iterating them for some business logic. Think, this application is being accessed by 1000 (1K) people simultaneously. In this simple scenario you are ending up with 10000000 (10Million or 1 Crore) iterations. below is the test scenario with simple console application to test 100 Million records. using System;using System.Collections.Generic;using System.Diagnostics;namespace ConsoleApplication1{ class Program { static void Main(string[] args) { var sw = new Stopwatch(); var numbers = GetSomeNumbers(); sw.Start(); foreach (var item in numbers) { } sw.Stop(); Console.WriteLine( String.Format("\"foreach\" took {0} milliseconds", sw.ElapsedMilliseconds)); sw.Reset(); sw.Start(); for (int i = 0; i < numbers.Count; i++) { } sw.Stop(); Console.WriteLine( String.Format("\"for\" loop took {0} milliseconds", sw.ElapsedMilliseconds)); sw.Reset(); sw.Start(); var it = 0; while (it++ < numbers.Count) { } sw.Stop(); Console.WriteLine( String.Format("\"while\" loop took {0} milliseconds", sw.ElapsedMilliseconds)); sw.Reset(); sw.Start(); var it2 = 0; do { } while (it2++ < numbers.Count); sw.Stop(); Console.WriteLine( String.Format("\"do-while\" loop took {0} milliseconds", sw.ElapsedMilliseconds)); } #region Get me 10Crore (100 Million) numbers private static List<int> GetSomeNumbers() { var lstNumbers = new List<int>(); var count = 100000000; for (var i = 1; i <= count; i++) { lstNumbers.Add(i); } return lstNumbers; } #endregion Get me some numbers }} In above example, I was just iterating through 100 Million numbers. You can see the time to execute various  loops provided in .NET Output "foreach" took 1108 milliseconds "for" loop took 727 milliseconds "while" loop took 596 milliseconds "do-while" loop took 594 milliseconds   Press any key to continue . . . So I feel we need to be careful while choosing the looping strategy. Please comment your thoughts. span.fullpost {display:none;}

  I can't publish in 2008, I was previously using 2005 and it published just fine. Error 2 An error occurred while signing: SignTool.exe not found. I know there are tons of hits for a search on signtool.exe on google.

• Android- Using DexClassLoader to load apk file.

  - by Craig O Connor

  Hi guys, I've hit a bit of a wall. Any help would be appreciated. I have an app that I want to use DexClassLoader to load another apk file. Here is my code: DexClassLoader dLoader = new DexClassLoader("/sdcard/download/test.apk","/sdcard/download",null,ClassLoader.getSystemClassLoader().getParent()); Class calledClass = dLoader.loadClass("com.test.classname"); Intent it=new Intent(this, calledClass); it.setClassName("com.test", "com.test.classname"); startActivity(it); Now I had already installed test.apk so when I ran the above code it worked fine and launched the application. However I want to be able to run this without test.apk being installed already (as that would defeat the entire point of the application) . So I uninstalled it and when I ran the my app again I get this error: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.test/com.test.classname}; have you declared this activity in your AndroidManifest.xml. So I'm a bit stumped here. This activity is declared in the Manifest of the apk I am trying to run. I can't declare it in my applications Manifest. Any ideas? Thanks, Craig

• MSBuild on TeamCity Server can't find AL.exe

  - by Tim Long

  I'm having a problem on my TeamCity CI build server where during compilation I get the following error: C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(2342, 9): error MSB3086: Task could not find "AL.exe" using the SdkToolsPath "" or the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v7.0A". Make sure the SdkToolsPath is set and the tool exists in the correct processor specific location under the SdkToolsPath and that the Microsoft Windows SDK is installed I've found similar reports from a year ago when people were upgrading to .NET 3.5, for example this one. In that case, installing the latest SDK solved the issue, however I have already installed the latest SDK (Microsoft Windows SDK for Windows 7 and .NET Framework 4) on my build server. The MSBuild tools are all there on the server, in a folder called C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319 and AL.exe exists in C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\NETFX 4.0 Tools However the registry key mentioned in the error message does not exist. So, it seems like there is something wrong with the installation/configuration of MSBuild. This error only happens for projects that have embedded resources, which require AL.exe. Please, anyone solved this issue or have any clues what's wrong?

• Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id.

  - by Irwin

  I'm working in ASP .NET dynamic data. In one of my edit controls I wanted to allow the user to add records from a related table to the current page. (Literally, if you are on the orders page, you would be allowed to add a new customer to the system on this page as well, and then associate it with that order). So, I have a DetailsView set to InsertMode, nested inside of an UpdatePanel, which is shown by a ModalPopupExtender which is invoked when 'add new' is clicked. This doohickey works the first time i execute this process, that is, a customer is added (and i update the dropdown list as well). However, I realized it didn't work (properly) again until I refreshed the entire page. When I attached my debugger, my worst fears were realized (ok, not really). But an exception was being thrown: "Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id." Which seemed to be complaining about a Calendar Extender Control that is part of the details view. Any guidance on what's going on here would be great. Thanks.

• MS Access 2003: Can data disappear from records and how do I test for this and prevent it?

  - by user328960

  Problem and about the database: Data from a record in Access 2003 database has disappeared. This database has 1 backend and 3 frontends, multiple users and is hosted on Citrix. Within this database, we have records of all clients served, ranging in the 1000s. Background info: The form for client data entry is set up with various subforms, including both a "programs enrolled" subform and a "services" subform. A client can be enrolled in multiple programs. Once enrolled in a program, services can be entered for that program area using the services subform. There are multiple fields in the services subform, one of which is a drop-down field allowing you to choose from the programs a client has been enrolled in (the list is updated for that client whenever he is enrolled in a new program). The problem details: For one specific record and one specific program area, the program has disappeared from the "programs enrolled" subform and all of the related services have disappeared from the "services" subform for a period of 3 months of data entry. However, other programs and services for this record did not disappear. Questions: Is the disappearance of data a common Access 2003 problem? Are there tests in place that can be run to see if data is disappearing and catch that data? If so, what are they? If there is specific code involved, what is it? What can be done to prevent the disappearing of data (other than using a different database)?

• iPhone UnitTesting UITextField value and otest error 133

  - by Justin Galzic

  Are UITextFields not meant to be part of the LogicTests and instead part of the ApplicationTest target? I have a factory class that is responsible for creating and returning an (iPhone) UITextField and I'm trying to unit test it. It is part of my Logic Test target and when I try to build and run the tests, I get a build error about: /Developer/Tools/RunPlatformUnitTests.include:451:0 Test rig '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.2.sdk/ 'Developer/usr/bin/otest' exited abnormally with code 133 (it may have crashed). In the build window, this points to the following line in: "RunPlatformUnitTests.include" RPUTIFail ${LINENO} "Test rig '${TEST_RIG}' exited abnormally with code ${TEST_RIG_RESULT} (it may have crashed)."

• Adding tables to a herd in bucardo

  Forgive my ignorance, I am a JS programmer given the task to do DB replication using bucardo. I understand the concept of how bucardo works, but setting it up is a bit confusing. The set-up is: Lubuntu Linux Two databases test_master and test_slave, using PostgreSQL Each DB has a table named test, containing 2 columns: id (PK) and test (int) I use pgAdmin3 I have already added them to bucardo's list of databases and added all tables. Table: public.test DB: test_slave PK: id (int4) Table: public.test DB: test_master PK: id (int4) As you see, due to the fact that the DBs are identical, even the schema names are identical. So when I do: bucardo_ctl add herd sample_herd public.test Ok, so it got added to the herd. But this command gets confused which database public.test comes from. So when I add a sync: $ bucardo_ctl add sync sample_sync source=sample_herd targetdb=test_slave type=fullcopy Failed to add sync: DBD::Pg::st execute failed: ERROR: Source and target databases cannot be the same: test_slave at line 118. at line 30. CONTEXT: PL/Perl function "validate_sync" at /usr/bin/bucardo_ctl line 3362. What does it mean that source and target cannot be the same? If it got confused as to which public.test to use as source, how do I differentiate?

• How can I test blades in MVC Turbine with Rhino Mocks?

  - by Brandon Linton

  I'm trying to set up blade unit tests in an MVC Turbine-derived site. The problem is that I can't seem to mock the IServiceLocator interface without hitting the following exception: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) at System.Reflection.Emit.TypeBuilder._TermCreateClass(Int32 handle, Module module) at System.Reflection.Emit.TypeBuilder.CreateTypeNoLock() at System.Reflection.Emit.TypeBuilder.CreateType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.InterfaceProxyWithTargetGenerator.GenerateCode(Type proxyTargetType, Type[] interfaces, ProxyGenerationOptions options) at Castle.DynamicProxy.DefaultProxyBuilder.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options, IInterceptor[] interceptors) at Rhino.Mocks.MockRepository.MockInterface(CreateMockState mockStateFactory, Type type, Type[] extras) at Rhino.Mocks.MockRepository.CreateMockObject(Type type, CreateMockState factory, Type[] extras, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.Stub(Type type, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.<>c__DisplayClass1`1.<GenerateStub>b__0(MockRepository repo) at Rhino.Mocks.MockRepository.CreateMockInReplay<T>(Func`2 createMock) at Rhino.Mocks.MockRepository.GenerateStub<T>(Object[] argumentsForConstructor) at XXX.BladeTest.SetUp() Everything I search for regarding this error leads me to 32-bit vs. 64-bit DLL compilation issues, but MVC Turbine uses the service locator facade everywhere and we haven't had any other issues, just with using Rhino Mocks to attempt mocking it. It blows up on the second line of this NUnit set up method: IRotorContext _context; IServiceLocator _locator; [SetUp] public void SetUp() { _context = MockRepository.GenerateStub<IRotorContext>(); _locator = MockRepository.GenerateStub<IServiceLocator>(); _context.Expect(x => x.ServiceLocator).Return(_locator); } Just a quick aside; I've tried implementing a fake implementing IServiceLocator, thinking that I could just keep track of calls to the type registration methods. This won't work in our setup, because we extend the service locator's interface in such a way that if the type isn't Unity-based, the registration logic is not invoked.
