  • How does Access 2007's moveNext/moveFirst/, etc., feature work?

    - by Chris M
    I'm not an Access expert, but am an SQL expert. I inherited an Access front-end referencing a SQL 2005 database that worked OK for about 5000 records, but is failing miserably for 800k records... Behind the scenes in the SQL profiler & activity manager I see some kind of Access query like: SELECT "MS1"."id" FROM "dbo"."customer" "MS1" ORDER BY "MS1"."id" The MS prefix doesn't appear in any Access code I can see. I'm suspicious of the built-in Access navigation code: DoCmd.GoToRecord , , acNext The GoToRecord has AcRecord constant, which includes things like acFirst, acLast, acNext, acPrevious and acGoTo. What does it mean in a database context to move to the "next" record? This particular table uses an identity column as the PK, so is it internally grabbing all the IDs and then moving to the one that is the next highest??? If so, how would it work if a table was comprised of three different fields for the PK? Or am I on the wrong track, and something else in Access is calling that statement? Unfortunately I see a ton of prepared statements in the profiler. THanks!

  • In Visual Studio 2010, how do you invoke the "View In Browser" feature on an MVC app?

    - by Chris
    In Visual Studio 2010, you can right-click an aspx page in a web forms app, or on the web forms app itself in the solution explorer, and you get "View in Browser" in your context menu. In ASP.NET MVC projects, this item doesn't seem to be available in the context menu. The only way I know to run the app is to set the MVC app as a startup project and hit CTRL+F5. But, if there are two MVC apps in the solution, this doesn't really work. How do you accomplish this for mvc apps?

  • How can I detect when the .NET Framework feature is "turned off" in Windows 7 / Vista?

    - by John Myczek
    My application requires the .NET Framework version 3.5. I recently ran into a customer that had the .NET Framework installed but turned off on Windows Vista (also applies to Windows 7). In this case, my installer (InstallShield 2009) does not prompt the user to install the Framework (because it is already installed) and when my application runs it crashes immediately. I tried another .NET application and it also crashes immediately. Is there any way to detect this situation and handle it more gracefully? Just detecting this during install is not ideal since the .NET Framework can be turned off at any time. Ideally, the application would be able to check and display a friendly message to the user telling them they need to turn on the .NET Framework. EDIT: "Turning off" the .NET Framework in Windows Vista or Windows 7 is not the same as uninstalling it. The Framework can be simply turned back on without reinstalling: http://windows.microsoft.com/en-US/windows-vista/Turn-Windows-features-on-or-off

  • Android: Maps - Best way to provide 'search for location' feature?

    - by r3mo
    Hello all, I've got an android app that uses a map activity and serves up content based on map location. I'm looking for a way to allow the user to search for a location by name (anything from 'New York' to 'Eiffel Tower') - e.g. have a text input field into which they could type 'Rome' - after pressing a button, the user would be brought to the coordinates of Rome on the map. What would be the best way to go about this? I've looked into the google geocoding api (http://code.google.com/apis/maps/documentation/geocoding/), but it has limitations of 2,500 geolocation requests per day - I'm presuming this is per API key? Or is it per user/source IP? 2,500 requests for one android app woudln't last long. Ideally, I would be able to search for English and foreign names of countries. Thanks in advance! r3mo

  • How to submit an app that uses an iOS6 feature?

    - by Darren
    I'm ready to submit my app to apple, however it says on the iOS Dev portal that xCode 4.5 cannot be used to submit apps yet, use the public release. xCode 4.4 wont compile my project because I am using -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } which is the new way to support orientation changes. It seems strange with iOS6 round the corner that I cannot submit this. Must I remove this and submit, then resubmit to support iOS6 when they allow it, or has anyone successfully submitted from xCode 4.5 beta 4? Thanks

  • Android phones: how does the video out feature work?

    - by confusedKid
    Hi, I'm searching for android phones that can use video out to the tv for a research project. I'm considering the HTC Touch Pro. Is there anything I have to do specifically to get the video out to work (for displaying my app on the tv)? or will the phone just display a running app on the tv without extra work? Thanks, I hope the post made sense =)

  • .NET's double.NaN - how does this counterintuitive feature work?

    - by GeReV
    I stumbled upon the definition of double.NaN in code: public const double NaN = (double)0.0 / (double)0.0; This is done similarly in PositiveInfinity and NegativeInfinity. double.IsNaN (with removing a few #pragmas and comments) is defined as: [Pure] [ReliabilityContract(Consistency.WillNotCorruptState, Cer.Success)] public static bool IsNaN(double d) { if (d != d) { return true; } else { return false; } } This is, by far, the most counterintuitive thing I have ever seen in the .NET framework. How is 0.0 / 0.0 represented "behind the scenes"? How can division by 0 be possible in double, and why does NaN != NaN?

  • Modernizr Rocks HTML5

    - by Laila
    HTML5 is a moving target.  At the moment, we don't know what will be in future versions.  In most circumstances, this really matters to the developer. When you're using Adobe Air, you can be reasonably sure what works, what is there, and what isn't, since you have a version of the browser built-in. With Metro, you can assume that you're going to be using at least IE 10.   If, however,  you are using HTML5 in a web application, then you are going to rely heavily on Feature Detection.  Feature-Detection is a collection of techniques that tell you, via JavaScript, whether the current browser has this feature natively implemented or not Feature Detection isn't just there for the esoteric stuff such as  Geo-location,  progress bars,  <canvas> support,  the new <input> types, Audio, Video, web workers or storage, but is required even for semantic markup, since old browsers make a pigs ear out of rendering this.  Feature detection can't rely just on reading the browser version and inferring from that what works. Instead, you must use JavaScript to check that an HTML5 feature is there before using it.  The problem with relying on the user-agent is that it takes a lot of historical data  to work out what version does what, and, anyway, the user-agent can be, and sometimes is, spoofed. The open-source library Modernizr  is just about the most essential  JavaScript library for anyone using HTML5, because it provides APIs to test for most of the CSS3 and HTML5 features before you use them, and is intelligent enough to alter semantic markup into 'legacy' 'markup  using shims  on page-load  for old browsers. It also allows you to check what video Codecs are installed for playing video. It also provides media queries  and conditional resource-loading (formerly YepNope.js.).  Generally, Modernizr gives you the choice of what you do about browsers that don't support the feature that you want. Often, the best choice is graceful degradation, but the resource-loading feature allows you to dynamically load JavaScript Shims to replace the standard API for missing or defective HTML5 functionality, called 'PolyFills'.  As the Modernizr site says 'Yes, not only can you use HTML5 today, but you can use it in the past, too!' The evolutionary progress of HTML5  requires a more defensive style of JavaScript programming where the programmer adopts a mindset of fearing the worst ( IE 6)  rather than assuming the best, whilst exploiting as many of the new HTML features as possible for the requirements of the site or HTML application.  Why would anyone want the distraction of developing their own techniques to do this when  Modernizr exists to do this for you?

  • Odd company release cycle: Go Distributed Source Control?

    - by MrLane
    sorry about this long post, but I think it is worth it! I have just started with a small .NET shop that operates quite a bit differently to other places that I have worked. Unlike any of my previous positions, the software written here is targetted at multiple customers and not every customer gets the latest release of the software at the same time. As such, there is no "current production version." When a customer does get an update, they also get all of the features added to he software since their last update, which could be a long time ago. The software is highly configurable and features can be turned on and off: so called "feature toggles." Release cycles are very tight here, in fact they are not on a shedule: when a feature is complete the software is deployed to the relevant customer. The team only last year moved from Visual Source Safe to Team Foundation Server. The problem is they still use TFS as if it were VSS and enforce Checkout locks on a single code branch. Whenever a bug fix gets put out into the field (even for a single customer) they simply build whatever is in TFS, test the bug was fixed and deploy to the customer! (Myself coming from a pharma and medical devices software background this is unbeliveable!). The result is that half baked dev code gets put into production without being even tested. Bugs are always slipping into release builds, but often a customer who just got a build will not see these bugs if they don't use the feature the bug is in. The director knows this is a problem as the company is starting to grow all of a sudden with some big clients coming on board and more smaller ones. I have been asked to look at source control options in order to eliminate deploying of buggy or unfinished code but to not sacrifice the somewhat asyncronous nature of the teams releases. I have used VSS, TFS, SVN and Bazaar in my career, but TFS is where most of my experience has been. Previously most teams I have worked with use a two or three branch solution of Dev-Test-Prod, where for a month developers work directly in Dev and then changes are merged to Test then Prod, or promoted "when its done" rather than on a fixed cycle. Automated builds were used, using either Cruise Control or Team Build. In my previous job Bazaar was used sitting on top of SVN: devs worked in their own small feature branches then pushed their changes to SVN (which was tied into TeamCity). This was nice in that it was easy to isolate changes and share them with other peoples branches. With both of these models there was a central dev and prod (and sometimes test) branch through which code was pushed (and labels were used to mark builds in prod from which releases were made...and these were made into branches for bug fixes to releases and merged back to dev). This doesn't really suit the way of working here, however: there is no order to when various features will be released, they get pushed when they are complete. With this requirement the "continuous integration" approach as I see it breaks down. To get a new feature out with continuous integration it has to be pushed via dev-test-prod and that will capture any unfinished work in dev. I am thinking that to overcome this we should go down a heavily feature branched model with NO dev-test-prod branches, rather the source should exist as a series of feature branches which when development work is complete are locked, tested, fixed, locked, tested and then released. Other feature branches can grab changes from other branches when they need/want, so eventually all changes get absorbed into everyone elses. This fits very much down a pure Bazaar model from what I experienced at my last job. As flexible as this sounds it just seems odd to not have a dev trunk or prod branch somewhere, and I am worried about branches forking never to re-integrate, or small late changes made that never get pulled across to other branches and developers complaining about merge disasters... What are peoples thoughts on this? A second final question: I am somewhat confused about the exact definition of distributed source control: some people seem to suggest it is about just not having a central repository like TFS or SVN, some say it is about being disconnected (SVN is 90% disconnected and TFS has a perfectly functional offline mode) and others say it is about Feature Branching and ease of merging between branches with no parent-child relationship (TFS also has baseless merging!). Perhaps this is a second question!

  • How to Reduce the Size of Your WinSXS Folder on Windows 7 or 8

    - by Chris Hoffman
    The WinSXS folder at C:\Windows\WinSXS is massive and continues to grow the longer you have Windows installed. This folder builds up unnecessary files over time, such as old versions of system components. This folder also contains files for uninstalled, disabled Windows components. Even if you don’t have a Windows component installed, it will be present in your WinSXS folder, taking up space. Why the WinSXS Folder Gets to Big The WinSXS folder contains all Windows system components. In fact, component files elsewhere in Windows are just links to files contained in the WinSXS folder. The WinSXS folder contains every operating system file. When Windows installs updates, it drops the new Windows component in the WinSXS folder and keeps the old component in the WinSXS folder. This means that every Windows Update you install increases the size of your WinSXS folder. This allows you to uninstall operating system updates from the Control Panel, which can be useful in the case of a buggy update — but it’s a feature that’s rarely used. Windows 7 dealt with this by including a feature that allows Windows to clean up old Windows update files after you install a new Windows service pack. The idea was that the system could be cleaned up regularly along with service packs. However, Windows 7 only saw one service pack — Service Pack 1 — released in 2010. Microsoft has no intention of launching another. This means that, for more than three years, Windows update uninstallation files have been building up on Windows 7 systems and couldn’t be easily removed. Clean Up Update Files To fix this problem, Microsoft recently backported a feature from Windows 8 to Windows 7. They did this without much fanfare — it was rolled out in a typical minor operating system update, the kind that don’t generally add new features. To clean up such update files, open the Disk Cleanup wizard (tap the Windows key, type “disk cleanup” into the Start menu, and press Enter). Click the Clean up System Files button, enable the Windows Update Cleanup option and click OK. If you’ve been using your Windows 7 system for a few years, you’ll likely be able to free several gigabytes of space. The next time you reboot after doing this, Windows will take a few minutes to clean up system files before you can log in and use your desktop. If you don’t see this feature in the Disk Cleanup window, you’re likely behind on your updates — install the latest updates from Windows Update. Windows 8 and 8.1 include built-in features that do this automatically. In fact, there’s a StartComponentCleanup scheduled task included with Windows that will automatically run in the background, cleaning up components 30 days after you’ve installed them. This 30-day period gives you time to uninstall an update if it causes problems. If you’d like to manually clean up updates, you can also use the Windows Update Cleanup option in the Disk Usage window, just as you can on Windows 7. (To open it, tap the Windows key, type “disk cleanup” to perform a search, and click the “Free up disk space by removing unnecessary files” shortcut that appears.) Windows 8.1 gives you more options, allowing you to forcibly remove all previous versions of uninstalled components, even ones that haven’t been around for more than 30 days. These commands must be run in an elevated Command Prompt — in other words, start the Command Prompt window as Administrator. For example, the following command will uninstall all previous versions of components without the scheduled task’s 30-day grace period: DISM.exe /online /Cleanup-Image /StartComponentCleanup The following command will remove files needed for uninstallation of service packs. You won’t be able to uninstall any currently installed service packs after running this command: DISM.exe /online /Cleanup-Image /SPSuperseded The following command will remove all old versions of every component. You won’t be able to uninstall any currently installed service packs or updates after this completes: DISM.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase Remove Features on Demand Modern versions of Windows allow you to enable or disable Windows features on demand. You’ll find a list of these features in the Windows Features window you can access from the Control Panel. Even features you don’t have installed — that is, the features you see unchecked in this window — are stored on your hard drive in your WinSXS folder. If you choose to install them, they’ll be made available from your WinSXS folder. This means you won’t have to download anything or provide Windows installation media to install these features. However, these features take up space. While this shouldn’t matter on typical computers, users with extremely low amounts of storage or Windows server administrators who want to slim their Windows installs down to the smallest possible set of system files may want to get these files off their hard drives. For this reason, Windows 8 added a new option that allows you to remove these uninstalled components from the WinSXS folder entirely, freeing up space. If you choose to install the removed components later, Windows will prompt you to download the component files from Microsoft. To do this, open a Command Prompt window as Administrator. Use the following command to see the features available to you: DISM.exe /Online /English /Get-Features /Format:Table You’ll see a table of feature names and their states. To remove a feature from your system, you’d use the following command, replacing NAME with the name of the feature you want to remove. You can get the feature name you need from the table above. DISM.exe /Online /Disable-Feature /featurename:NAME /Remove If you run the /GetFeatures command again, you’ll now see that the feature has a status of “Disabled with Payload Removed” instead of just “Disabled.” That’s how you know it’s not taking up space on your computer’s hard drive. If you’re trying to slim down a Windows system as much as possible, be sure to check out our lists of ways to free up disk space on Windows and reduce the space used by system files.

  • Time to stop using &ldquo;Execute Package Task&rdquo;&ndash; a way to execute package in SSIS catalog taking advantage of the new project deployment model ,and the logging and reporting feature

    - by Kevin Shyr
    I set out to find a way to dynamically call package in SSIS 2012.  The following are 2 excellent blogs I found; I used them heavily.  The code below has some addition to parameter types and message types, but was made essentially derived entirely from the blogs. http://sqlblog.com/blogs/jamie_thomson/archive/2011/07/16/ssis-logging-in-denali.aspx http://www.ssistalk.com/2012/07/24/quick-tip-run-ssis-2012-packages-synchronously-and-other-execution-options/   The code: Every package will be called by a PackageController package.  The packageController is initialized with some information on which package to run and what information to pass in.   The following is the stored procedure called from the “Execute SQL Task”.  Here is the highlight of the stored procedure It takes in packageName, project name, and folder name (folder in SSIS project deployment to SSIS catalog) The stored procedure sets the package variables of the upcoming package execution Execute package in SSIS Catalog Get the status of the execution.  Also, if exists, get the error message’s message_id and store them in the management database. Return value to “Execute SQL Task” to manage failure properly CREATE PROCEDURE [AUDIT].[LaunchPackageExecutionInSSISCatalog]        @PackageName NVARCHAR(255)        , @ProjectFolder NVARCHAR(255)        , @ProjectName NVARCHAR(255)        , @AuditKey INT        , @DisableNotification BIT        , @PackageExecutionLogID INT AS BEGIN TRY        DECLARE @execution_id BIGINT = 0;

  • Mark Zuckerberg tops the list of 50 Highest Rated CEOs. 3 Indian CEOs feature in the list.

    - by Gopinath
    Mark Zuckerberg, the CEO of Facebook is rated as the best CEO according to a report released by the popular employee reviews website Glassdoor.com. 50,000 employees reviews submitted to Glassdoor in the past 1 year are considered for preparing the rating list and Zukerberg topped the list with 99 percent approval to the question “Do you approve of the way your CEO is leading the company?”. Wow! That’s an amazing support to Zukergerg from his employees though stock market and share holders are not with him. Coincidently Facebook is also rated as the best company to work by Glassdoor in a recent survey. Here is the list of top 10 CEOs Mark Zuckerberg, Facebook; 99.3% Approval Bill McDermott & Jim Hagemann Snabe, SAP; 99% Approval Dominic Barton, McKinsey & Company; 97% Approval Jim Turley, Ernst & Young; 96% Approval John E. Schlifske, Northwestern Mutual; 96% Approval Frank D’Souza, Cognizant Technology Solutions; 96% Approval Joe Tucci, EMC; 96% Approval Paul E. Jacobs, QUALCOMM; 95% Approval Richard K. Davis, U.S. Bank; 95% Approval Pierre Nanterme, Accenture; 95% Approval 3 Indian CEOs in the top 50 list – TCS, Wipro & MindTree The list featured three Indian CEOs and all the three are leading Software IT Services organizations in India and creating thousands of IT jobs.  Natarajan Chandrasekaran – the CEO of TCS is at 25th position, Krishnakumar Natarajan – the CEO of MindTree is at 28th position and  Wipro’s T.K.Kurien is at 44th position. Glad to see Indian CEO joining the global ranks. Tech Heavy Weights Google, Apple, Amazon & Microsoft aren’t in top 10 Another thing to note from this report is that the CEO’s of technology heavy weights Google, Apple, Amazon and Microsoft are not in the top10 list- looks like their employees are not really happy with their bosses. At least not as happy as their peers at Facebook. Google CEO’s Larry Page is at 11th position, Jeff Bezos of Amazon at 16th position and Tim Cook of Apple is at 18th position. Well the Microsoft CEO is not even in the list of top 50!! You can read the complete list of ratings at Glassdoor.com’s blog. Photo Credit: Andrew Feinberg

  • Does HTML5 have a feature that enables a user to add an icon to the Apps screen when "installing", and if not, when are they planning to add it?

    - by Jason Livesay
    I know that the mobile bookmark bubble might sort of work for iOS, but it isn't going in the same section. And for Android, bookmarking is really not going to cut it for a mobile HTML5 application install since users just don't think to go to their bookmarks and that bookmark process takes two or three steps. To me this issue of getting the application (bookmark) installed pretty much makes the rest of the HTML 5 features aimed at mobile HTML much less useful. I can't realistically expect users to prefer the bookmark install and launch process over regular apps, so I can realistically expect them to ignore my mobile HTML5 application and use a native app. The groups behind mobile HTML 5 features do seem to be pushing for HTML 5 apps adoption with things like Application Cache etc. To me it seems obvious that the bookmark bubble is not going to cut it. Someone please tell me they have addressed this or at least are working on it?
