  • Print raw data to a thermal-printer using c#

    - by blauesocke
    Hi, I'm trying to print out raw ascii data to a thermal printer. I do this by using this code example: http://support.microsoft.com/kb/322091 but my printer prints always only one character and this not until I press the form feed button. If I print something with notepad the printer will do a form feed automatically but without printing any text. The printer is connected via usb over a lpt2usb adapter and Windows 7 uses the "Generic - Generic / Text Only" driver. Anyone knows what is going wrong? How is it possible to print some words and do some form feeds? Are there some control characters I have to send? And if yes: How do I send them? Thanks!

  • How to inject AutoMapper IMappingEngine with StructureMap

    - by Jay Walker
    Most of the examples I've found for Automapper use the static Mapper object for managing type mappings. For my project, I need to inject an IMapperEngine as part of object construction using StructureMap so that we can mock the mapper in unit tests so we can't use the static mapper. I also need to support configuring AutoMapper Profiles. My question is how can I configure the StructureMap registry so that it can supply an instance of IMappingEngine when an instance of MyService is constructed. Here is the Service constructor signature: public MyService(IMappingEngine mapper, IMyRepository myRepository, ILogger logger) And here is the StructureMap Registry public class MyRegistry : StructureMap.Configuration.DSL.Registry { public MyRegistry() { For<IMyRepository>().Use<MyRepository>(); For<ILogger>().Use<Logger>(); //what to do for IMappingEngine? } } And the profile I want to load public class MyAutoMapperProfile : AutoMapper.Profile { protected override void Configure() { this.CreateMap<MyModel, MyDTO>(); } }

  • Visual studio 2008 problem

    - by Thomas Manalil
    i am using visual studio team system 2008 and VSS 2005. I took a latest copy of a project from VSS. Now when i try to open that project, it is showing error "This version of visual studio does not support source control" and " Unexpected error enocountered. Restart the application Error : no such interfaces are supported File : vsee\internal\vscomptr.inl". When i open solution explorer, all projects are showing as unavailable. I tried VS--Tools--options-- source control--plugin selection and set plug in to Microsoft "Visual source safe" and when i open "Environment" tab it is showing "an error occured while loading this property page" Can someone help me???

  • Problems deploying MVC2 - Could not load type 'System.Web.Mvc.UrlParameter'

    - by Evgeny
    Hi Everyone, I have problems deploying MVC2 application to my hosting. It shows the following error: Could not load type 'System.Web.Mvc.UrlParameter' from assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. It looks like it does not understand the new "optional URL parameters" feature of MVC2. This is just a simple test application I created with "New Project" wizard in VWD 2008. It works ok localy both in IIS and Visual Studio web servers. MVC1 web sites are working ok on the hosting server. I've contacted the hosting support and they installed MVC2 but the problem still exists. The web site is working in ASP.NET 2.0 integrated pipeline mode. Does anyone know why it is happening? Thank you!

  • IntelliJ 12 - Grails Distribution in specified path is broken

    - by Prayag Upd
    I am struggling to configure grails 2.3.X in IntelliJ idea 12. Grails 2.2.X is configured successfully. Grails 2.3.2 is working properly from terminal. I can compile, test, run my application. But while trying to configure it in IntelliJ so that dependencies get resolved, I get the IntelliJ shouting straight to me(as pictured below). Looks like Grails Distribution in specified path is broken. Cannot determinate version. What I see is changes in grails-2.3.x/dist/ to earlier version's grails-2.2.x/dist/. Is this because there's no support for newer version(2.3.x) of grails in IntelliJ 12 or what ? I want nothing else but my application (jar) dependencies to be resolved in the IDE.

  • iPhone file extension app association - Reloaded

    - by MihaiD
    On the subject of associating your iPhone app with file types. In this informative question I learned that apps could be associated with custom URL protocols. That was almost one year ago and since then Apple introduced 'Document Support' which goes a step further and allows apps to associate with file types. There is a lot of talk in the documentation about how to set up your app to launch other appropriate apps when it encounters an unknown file type. This means the association doesn't work out of the box for any app, like the URL protocol registering did. This leads me to the question: have system apps like Safari or Mail implemented this system for choosing associated applications, or will they do nothing, as before?

  • Android SlidingDrawer in Eclipse IDE

    - by user295447
    I am trying to design an application for Android that makes use of the SlidingDrawer, but I have not been able to use the form (layout?) designer to add this element without producing an exception "IllegalArgumentException: The handle attribute is required and must refer to a valid child." As of March 17th, I believe I have everything up to date (Eclipse, and the Android SDK). All the SDK components have been installed. I have created two Android virtual devices, One for version 1.0, and one for version 2.1 when I figured out that 1.0 didn't support the SlidingDrawer. I have tried importing the samples provided in the SDK, as well as several other layouts from the web that I have found, all of which produce this same exception. My programming background is mostly C++, and I consider myself to be a novice programmer, so feel free to talk to me as if I were an idiot so that I will understand. ^^;

  • Importing Multiple Schemas to a Model in Oracle SQL Developer Data Modeler

    - by thatjeffsmith
    Your physical data model might stretch across multiple Oracle schemas. Or maybe you just want a single diagram containing tables, views, etc. spanning more than a single user in the database. The process for importing a data dictionary is the same, regardless if you want to suck in objects from one schema, or many schemas. Let’s take a quick look at how to get started with a data dictionary import. I’m using Oracle SQL Developer in this example. The process is nearly identical in Oracle SQL Developer Data Modeler – the only difference being you’ll use the ‘File’ menu to get started versus the ‘File – Data Modeler’ menu in SQL Developer. Remember, the functionality is exactly the same whether you use SQL Developer or SQL Developer Data Modeler when it comes to the data modeling features – you’ll just have a cleaner user interface in SQL Developer Data Modeler. Importing a Data Dictionary to a Model You’ll want to open or create your model first. You can import objects to an existing or new model. The easiest way to get started is to simply open the ‘Browser’ under the View menu. The Browser allows you to navigate your open designs/models You’ll see an ‘Untitled_1′ model by default. I’ve renamed mine to ‘hr_sh_scott_demo.’ Now go back to the File menu, and expand the ‘Data Modeler’ section, and select ‘Import – Data Dictionary.’ This is a fancy way of saying, ‘suck objects out of the database into my model’ Connect! If you haven’t already defined a connection to the database you want to reverse engineer, you’ll need to do that now. I’m going to assume you already have that connection – so select it, and hit the ‘Next’ button. Select the Schema(s) to be imported Select one or more schemas you want to import The schemas selected on this page of the wizard will dictate the lists of tables, views, synonyms, and everything else you can choose from in the next wizard step to import. For brevity, I have selected ALL tables, views, and synonyms from 3 different schemas: HR SCOTT SH Once I hit the ‘Finish’ button in the wizard, SQL Developer will interrogate the database and add the objects to our model. The Big Model and the 3 Little Models I can now see ALL of the objects I just imported in the ‘hr_sh_scott_demo’ relational model in my design tree, and in my relational diagram. Quick Tip: Oracle SQL Developer calls what most folks think of as a ‘Physical Model’ the ‘Relational Model.’ Same difference, mostly. In SQL Developer, a Physical model allows you to define partitioning schemes, advanced storage parameters, and add your PL/SQL code. You can have multiple physical models per relational models. For example I might have a 4 Node RAC in Production that uses partitioning, but in test/dev, only have a single instance with no partitioning. I can have models for both of those physical implementations. The list of tables in my relational model Wouldn’t it be nice if I could segregate the objects based on their schema? Good news, you can! And it’s done by default Several of you might already know where I’m going with this – SUBVIEWS. You can easily create a ‘SubView’ by selecting one or more objects in your model or diagram and add them to a new SubView. SubViews are just mini-models. They contain a subset of objects from the main model. This is very handy when you want to break your model into smaller, more digestible parts. The model information is identical across the model and subviews, so you don’t have to worry about making a change in one place and not having it propagate across your design. SubViews can be used as filters when you create reports and exports as well. So instead of generating a PDF for everything, just show me what’s in my ‘ABC’ subview. But, I don’t want to do any work! Remember, I’m really lazy. More good news – it’s already done by default! The schemas are automatically used to create default SubViews Auto-Navigate to the Object in the Diagram In the subview tree node, right-click on the object you want to navigate to. You can ask to be taken to the main model view or to the SubView location. If you haven’t already opened the SubView in the diagram, it will be automatically opened for you. The SubView diagram only contains the objects from that SubView Your SubView might still be pretty big, many dozens of objects, so don’t forget about the ‘Navigator‘ either! In summary, use the ‘Import’ feature to add existing database objects to your model. If you import from multiple schemas, take advantage of the default schema based SubViews to help you manage your models! Sometimes less is more!

  • How to access the FirstData web service integration WSDL file?

    - by rcampbell
    FirstData has horrendous customer support, but I have to integrate with their Global Gateway web service for a project I'm working on. I'm simply trying to run the Axis2 wsdl2java tool according to the instructions in their manual. This basically consists of adding the keyStore and keyStorePassword JVM parameter. I've done both, but I continue to get Connection reset errors when trying to run: wsdl2java.bat -uri https://www.staging.linkpointcentral.com/fdggwsapi/order.wsdl -S C:\ When I try to access the URL with my browser, I get Error 101 (net::ERR_CONNECTION_RESET): Unknown error. I assume there are developers out there who have completed a FirstData web service integration. What am I doing wrong? I've also tried connecting via cURL: C:\curl-7.19.7-ssl-sspi-zlib-static-bin-w32>curl --cert C:\FDGGWS\WSXXXXXXXXXX._.1.pem --key C:\FDGGWS\WSXXXXXXXXXX._.1.key --insecure https://www.staging.linkpointcentral.com/fdggwsapi/order.wsdl Enter PEM pass phrase: curl: (52) SSL read: error:00000000:lib(0):func(0):reason(0), errno 10054 I know I'm entering the correct key password because when I enter a fake one I get: curl: (58) unable to set private key file: 'C:\FDGGWS\WSXXXXXXXXXX._.1.key' type PEM

  • Sync database with filter using SyncOrchestrator with Sync Framework 2.0

    - by Flo
    Hi, I want to synchronize two SQL databases. But since one of the databases only requires a subset of the data I am looking for a filter option. Is there a possibility to add a Filter to the SyncOrchestrator or do I have to add the filter to the SyncProvider? According to this: http://social.microsoft.com/Forums/en-US/uklaunch2007ado.net/thread/35d4deb8-a861-4fe3-a395-d175e14c353f it is not possible to filter with the DbSyncProvider. Quote: "I understand your scenario, and the hebavior of the DbSyncProvider is due to the current limitation. DbSyncProvider is built on top of the Microsoft Sync Framework that can support filtering. Unfortunately, DbSyncProvider does not yet." But that post is quite old, maybe that has changed now. I am working with this example at the moment: http://msdn.microsoft.com/en-us/library/cc807255.aspx but I can't figure out how to add filtering here.

  • HTML5 video tag in chrome - wmv

    - by elcuco
    Hi Al, I need to make a page which displays a video. Firefox and and Opera support the OGG format, no problem there. Chrome is ... "stupid" and does not recognize OGG. Does Chrome on Windows know how to handle WMV? I already have them encoded, and no I cannot recode new videos since the media is limited in spaced (CDROM). My code currently looks like this (and not working in chrome) <video controls> <source codecs="theora, vorbis" media="video/ogg" src="video.ogv" /> <source media="video/x-ms-wmv" src="video.wmv" /> Please install a new browser, or just get out </video> Note that I am missing a codec entry, does anyone know what I need to put there?

    - by user285037
    Hi I am working on a desktop application which uses Infragistic grids. We need to automate the regression tests for same. QTP alone does not support this, we need to buy new plug in for same which my company is not very much interested in. Do we have any open source tool for automating regression testing of desktop application? Application is in Dot net but i do not think it makes much of a difference. Please suggests, i have zeroed in for test complete but again it is licensed one. I need some open source.

  • C: WinAPI CreateDIBitmap() from byte[] problem

    - by zipcodeman
    I have been working on this problem for a while now. I am trying to add JPEG support to a program with libjpeg. For the most part, it is working fairly well, But for some JPEGs, they show up like the picture on the left. It may not be obvious, but the background shows up with alternating red green and blue rows. If anyone has seen this behavior before and knows a probable cause, I would appreciate any input. I have padded the rows to be multiples of four bytes, and it only slightly helped the issue.

  • JQuery Tools Overlay for modal dialog broken under IE8

    - by Gary McGill
    I've been developing a website that has several modal dialog boxes. I've been using jQuery Tools Overlay for the dialog boxes. However, I've just discovered that it doesn't seem to work properly on IE8. In Chrome (and I presume other browsers), the dialog is highlighted by darkening the rest of the page "below" it, but on IE8 the page "below" is obliterated - all you get is the dialog on a black background. This appears to be nothing to do with the way I've configured it - the same problem is evident on the jQuery Tools website itself. If you click the link above and then click one of the two buttons headed "For User Interactions", then you'll see what I mean. What's the deal? Does it simply not support IE8? If so, (a) grrrr... and (b) what else should I use?

  • Scrum Master Stephen Forte Teaches Agile Development, Silverlight and BI at GIDS 2010

    - by rajesh ahuja
    Great Indian Developer Summit 2010 – Gold Standard for India's Software Developer Ecosystem Bangalore, March 25, 2010: The author of several books on application and database development including Programming SQL Server 2008 and certified Scrum Master Stephen Forte is coming this summer to India's biggest summit for the developer ecosystem - Great Indian Developer Summit. At the summit, Stephen will conduct a workshop guaranteed to give attendees a jump start in taking a certified scrum master exam. Scrum, one of the most popular Agile project management and development methods, which is starting to be adopted at major corporations and on very large projects. After an introduction to the basics of Scrum like project planning and estimation, the Scrum Master, team, product owner and burn down, and of course the daily Scrum, Stephen will show many real world applications of the methodology drawn from his own experience as a Scrum Master. Negotiating with the business, estimation and team dynamics are all discussed as well as how to use Scrum in small organizations, large enterprise environments and consulting environments. Stephen will also discuss using Scrum with virtual teams and an off-shoring environment. He will then take a look at the tools we will use for Agile development, including planning poker, unit testing, and much more. On 20th April at the GIDS.NET Conference, Stephen will also conduct a series of sessions on Microsoft computing technologies. He will teach how to build data driven, n-tier Rich Internet Applications (RIA) with Silverlight 4.0. Line of business applications (LOB) in Silverlight 4.0 are easy by tapping the power of WCF RIA Services, the Silverlight Toolkit, and elevated out of browser support. Stephen's demo centric session will walk you through an example of building a LOB application with Silverlight 4.0. See how Silverlight and WCF RIA Services support domain logic, services, data binding, validation, server based paging, authentication, authorization and much more. Silverlight 4.0 means business. Silverlight runs C# and Visual Basic code, and so it seems natural that a business application might share some code between the Silverlight client and its ASP.NET Web server. You may want to run some code client-side for interactivity, but re-run that code on the server for security or reliability. This is possible, and there are several techniques you can use to accomplish this goal. In Stephen's second talk learn about the various techniques and their pros and cons. Some techniques work better in C#, others in VB. Still others are simpler with a little extra tooling or code-generation. Any serious Silverlight business application will almost certainly face this issue, and this session gets you going fast. In the third talk, Stephen will explain how to properly architect and deploy a BI application using a mix of some exciting new tools and some old familiar ones. He will start with a traditional relational transaction centric database (OLTP) and explore ways to build a data warehouse (OLAP), looking at the star and snowflake schemas. Next he will look at the process of extraction, transformation, and loading (ETL) your OLTP data into your data warehouse. Different techniques for ETL will be described and the various tradeoffs will be discussed. Then he will look at using the warehouse for reporting, drill down, and data analysis in Microsoft Excel's PowerPivot 2010. The session will round off by showing how to properly build a cube and build a data analysis application on top of that cube, and conclude by looking at some tools to help with the data visualization process. Every year, GIDS is a game changer for several thousands of IT professionals, providing them with a competitive edge over their peers, enlightening them with bleeding-edge information most useful in their daily jobs, helping them network with world-class experts and visionaries, and providing them with a much needed thrust in their careers.

  • Image map popup on rollover, with popup text drawn from database

    - by lbholland
    I have a custom map of the USA with about 20 polygonal hot spots. I would like a box to pop up next to each hot spot on hover, with text and links drawn from my DB specific to the location. I would have thought this is a common situation, but I can't find a solution that works. I tried using an asp:imagemap and an ajax popup extender but you can't assign IDs to hotspots and it doesn't support mouseover events. I tried css with an html image map but I can't figure out how to use css solutions with polygonal hot spots, and I also don't know how to link it to get the data from the db without asp targets (I'm not very familiar with jquery, which would work, I am guessing). Anyone know of any simple-ish solutions out there?

  • iphone - How do I add videos to iPad simulator?

    - by Mike
    No, dropping the videos to ~/Library/Application Support/iPhone Simulator/3.2/Media/DCIM/100APPLE does not work totally, because the simulator can see the video on Photos.app, but when I try to pick a video using UIImagePickerController my application crashes. I think this may have some relation to the format the video has to have. I am using QuickTime to generate the video. I am using the settings "for iPhone"... so it is generating a M4V with 480x360 pixels H264. I have tried to create a MOV with the same characteristics and one with 640x480 but nothing works. I have also dropped a movie created with iPhone 3GS and it still crashes. this is the error I see when it crashes * Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (1) beyond bounds (0)' the method didFinishPickingMediaWithInfo is never called, so its some issue on the simulator or on the video. The app crashes as soon as I pick the video. any ideas? thanks.

  • CruiseControl [.Net] vs TeamCity for continuous integration?

    - by zappan
    i would like to ask you which automated build environment you consider better, based on practical experience. i'm planning to do some .Net and some Java development, so i would like to have a tool that supports both these platforms. i've been reading around and found out about CruiseControl.NET, used on stackoverflow development, and TeamCity with its support for build agents on different OS-platforms and based on different programming languages. so, if you have some practical experience on both of those, which one you prefer and why. currently, i'm mostly interested in the ease of use and management of the tool, much less in the fact that CC is open source, and TC is a subject to licensing at some point when you have much projects to run (because, i need it for a small amount of projects). also, if there is some other tool that meets the above-mentioned and you believe it's worth a recommendation - feel free to include it in the discussion.

    - by Matthew Guay
    Want to breathe new life into your netbook?  Here’s a quick look at Jolicloud, a unique new Linux based OS that lets you use your netbook in a whole new way. Netbooks have been an interesting category of computers.  When they were first released, most netbooks came with a stripped down Linux based operating system designed to let you easily access the internet first and foremost.  Consumers wanted more from their netbooks, so full OSes such as Windows XP and Ubuntu became the standard on netbooks.  Microsoft worked hard to get Windows 7 working great on netbooks, and today most netbooks run Windows 7 great.  But the Linux community hasn’t stood still either, and Jolicloud is proof of that.  Jolicloud is a unique OS designed to bring the best of both webapps and standard programs to your netbook.   Keep reading to see if this is the perfect netbook OS for you. Getting Started Installing Jolicloud on your netbook is easy thanks to a the Jolicloud Express installer for Windows.  Since many netbooks run Windows by default, this makes it easy to install Jolicloud.  Plus, your Windows install is left untouched, so you can still easily access all your Windows files and programs. Download and run the roughly 700Mb installer (link below) just as a normal installer in Windows. This will first extract the needed files. Click Get started to install Jolicloud on your netbook. Enter a username, password, and nickname for your computer.  Please note that the username must be all lowercase, and the nickname should not contain spaces or special characters.   Now you can review the default installation settings.  By default it will take up 39Gb and install on your C:\ drive in English.  If you wish to change this, click Change. We chose to install it on the D: drive on this netbook, as its harddrive was already partitioned into two parts.  Click Save when your settings are all correct, and then click Next in the previous window. Jolicloud will prepare for the installation.  This took about 5 minutes in our test.  Click Next when this is finished. Click Restart now to install and run Jolicloud. When your netbook reboots, it will initialize the Jolicloud setup. It will then automatically finish the installation.  Just sit back and wait; there’s nothing for you to do right now.  The installation took about 20 minutes in our test. Jolicloud will automatically reboot when the setup is finished. Once it’s rebooted, you’re ready to go!  Enter the username, then the password, that you chose earlier when you were installing Jolicloud from Windows. Welcome to your Jolicloud desktop! Hardware Support We installed Jolicloud on a Samsung N150 netbook with an Atom N450 processor, 1Gb Ram, 250Gb harddrive, and WiFi b/g/n with Bluetooth.  Amazingly, once Jolicloud was installed, everything was ready to use.  No drivers to install, no settings to hassle with, it was all installed and set up perfectly.  Power settings worked great, and closing the netbook put it to sleep just like in Windows. WiFi drivers have typically been difficult to find and install on Linux, but Jolicloud had our netbook’s wifi working immediately.  To get online, simply click the Wireless icon on the top right, and select the wireless network you want to connect to. Jolicloud will let you know when it is signed on. Wired Lan networking was also seamless; simply connect your cable and you’re ready to go.  The webcam and touchpad also worked perfectly directly.  The only thing missing was multitouch; this touchpad has two finger scroll, pinch zoom, and other nice multitouch features in Windows, but in Julicloud it only functioned as a standard touchpad.  It did have tap to click activated by default, as well as right-side scrolling, which is nice. Jolicloud also supported our video card without any extra work.  The native resolution was already selected, and the only problem we had with the screen was that there was no apparent way to change the brightness.  This is not a major problem, but would be nice to have.  The Samsung N150 has Intel GMA3150 integrated graphics, and Jolicloud promises 1080p HD video on it.  It did playback 720p H.264 video flawlessly without installing anything extra, but it stuttered on full 1080p HD (which is the exact same as this netbook’s video playback in Windows 7 – 720p works great, but it stutters on 1080p).  We would be excited to see full HD on this netbook, but 720p is definitely fine for most stuff.   Jolicloud supports a wide range of netbooks, and based on our experience we would expect it to work as good on any supported hardware.  Check out the list of supported netbooks to see if your netbook is supported; if not, it still may work but you may have to install special drivers. Jolicloud’s performance was very similar to Windows 7 on our netbook.  It boots in about 30 seconds, and apps load fairly quickly.  In general, we couldn’t tell much difference in performance between Jolicloud and Windows 7, though this isn’t a problem since Windows 7 runs great on the current generation of netbooks. Using Jolicloud Ready to start putting Jolicloud to use?  Your fresh Jolicloud install you can run several built-in apps, such as Firefox, a calculator, and the chat client Pidgin.  It also has a media player and file viewer installed, so you can play MP3s or MPG videos, or read PDF ebooks without installing anything extra.  It also has Flash player installed so you can watch videos online easily. You can also directly access all of your files from the right side of your home screen.  You can even access your Windows files; in our test, the 116.9 GB Media was C: from Windows.  Select it to browse and open any file you had saved in Windows. You may need to enter your password to access it. Once you’re authenticated it, you’ll see all of your Windows files and folders.  Your User files (Documents, Music, Videos, etc.) will be in the Users folder. And, you can easily add files from removable media such as USB flash drives and memory cards.  Jolicloud recognized a flash drive we tested with no trouble at all. Add new apps But, the best part about Jolicloud is that it makes it very easy to install new apps.  Click the Get Started button on your homescreen. You’ll first need to create an account.  You can then use this same account on another netbook if you wish, and your settings will automatically be synced between the two. You can either signup using your Facebook account, …or you can sign up the traditional way with your email address, name, and password.  If you sign up this way, you will need to confirm your email address before your account will be finished. Now, choose your netbook model from the list, and enter a name for your computer. And that’s it!  You’ll now see the Jolicloud dashboard, which will show you updates and notifications from friends who also use Jolicloud. Click the App directory to find new apps for your netbook.  Here you will find a variety of webapps, such as Gmail, along with native applications, such as Skype, that you can install on your netbook.  Simply click the Install button on the right to add the app to your netbook. You will be prompted to enter your system password, and then the app will install without any further input.   Once an app is installed, a check mark will appear beside its name.  You can remove it by clicking the Remove button, and it will uninstall seamlessly. Webapps, such as Gmail, actually run in in a Chrome-powered window that lets the webapp run full screen.  This gives the webapps a native feel, but actually they’re just running the same as they would in a standard web browser.   The Jolicloud Interface Most apps run maximized, and there is no way to run them smaller.  This in general works good, since with small screens most apps need to run full-screen anyhow. Smaller apps, such as a calculator or the Pidgin chat client, run in a window just like they do on other operating systems. You can switch to another app that’s running by selecting it’s icon on the top left, or you can go back to the home screen by clicking the home screen.  If you’re finished with an program, simply click the red X button on the top right of the window when you’re running it. Or, you can switch between programs using standard keyboard shortcuts such as Alt-tab. The default page on the home screen is the favorites page, and all of your other programs are orginized in their own sections on the left hand side.  But, if you want to add one of these to your favorites page, simply right-click on it and select Add to Favorites. When you’re done for the day, you can simply close your netbook to put it to sleep.  Or, if you want to shut down, just press the Quit button on the bottom right of the home screen and then select Shut Down. Booting Jolicloud When you install Jolicloud, it will set itself as the default operating system.  Now, when you boot your netbook, it will show you a list of installed operating systems.  You can select either Windows or Jolicloud, but if you don’t make a selection it will boot into Jolicloud after waiting 10 seconds. If you’d perfer to boot into Windows by default, you can easily change this.  First, boot your netbook in to Windows.  Open the start menu, right-click on the Computer button, and select Properties.   Click the “Advanced system settings” link on the left side. Click the Settings button in the Startup and Recovery section. Now, select Windows as the default operating system, and click Ok.  Your netbook will now boot into Windows by default, but will give you 10 seconds to choose to boot into Jolicloud when you start your computer. Or, if you decided you don’t want Jolicloud, you can easily uninstall it from within Windows. Please note that this will also remove any files you may have saved in Jolicloud, so be sure to copy them to your Windows drive before uninstalling. To uninstall Jolicloud from within Windows, open Control Panel, and select Uninstall a Program. Scroll down to select Jolicloud, and click Uninstall/Change. Click Yes to confirm that you want to uninstall Jolicloud. After a few moments, it will let you know that Jolicloud has been uninstalled.  You’re netbook is now back the same as it was before you installed Jolicloud, with only Windows installed. Closing Whether you’re wanting to replace your current OS on your netbook or would simply like to try out a fresh new Linux version on your netbook, Jolicloud is a great option for you.  We were very impressed by it’s solid hardware support and the ease of installing new apps in Jolicloud.  Rather than simply giving us a standard OS, Jolicloud offers a unique way to use your netbook with native programs and webapps.  And whether you’re an IT pro or are a new computer user, Jolicloud was easy enough to use that anyone can do it.  Give it a try, and let us know what your favorite netbook OS is!

  • Proper way to add record to many to many relationship in Django

    - by blcArmadillo
    First off, I'm planning on running my project on google app engine so I'm using djangoappengine which as far as I know doesn't support django's ManyToManyField type. Because of this I've setup my models like this: from django.db import models from django.contrib.auth.models import User class Group(models.Model): name = models.CharField(max_length=200) class UserGroup(models.Model): user = models.ForeignKey(User) group = models.ForeignKey(Group) On a page I have a form field where people can enter a group name. I want the results from this form field to create a UserGroup object for the user - group combination and if the group doesn't yet exist create a new Group object. At first I started putting this logic in the UserGroup class with a add_group method but quickly realized that it doesn't really make sense to put this in the UserGroup class. What would the proper way of doing this be? I saw some stuff about model managers. Is this what those are for?

  • How to keep asm output from Linux kernel module build

    - by fastmonkeywheels
    I'm working on a Linux kernel module for a 2.6.x kernel and I need to view the assembly output, though it's currently being done as a temporary file an deleted afterwords. I'd like to have the assembly output mixed with my C source file so I can easily trace where my problem lies. This is for an ARMv6 core and apparently objdump doesn't support this architecture. I've included my makefile below. ETREP=/xxSourceTreexx/ GNU_BIN=$(ETREP)/arm-none-linux-gnueabi/bin CROSS_COMPILE := $(GNU_BIN)/arm-none-linux-gnueabi- ARCH := arm KDIR=$(ETREP)/linux-2.6.31/ MAKE= CROSS_COMPILE=$(CROSS_COMPILE) ARCH=$(ARCH) make obj-m += xxfile1xx.o all: $(MAKE) -C $(KDIR) M=$(PWD) modules clean: $(MAKE) -C $(KDIR) M=$(PWD) clean

  • Hide/ change width/ change position of UIButton based on device type

    - by Giles Van Gruisen
    I'm using the new in-app SMS features in my iPhone app, but obviously iPod Touches aren't able to send and receive SMS without support of a third party app. I know all well how to detect the device and how to hide a UIButton, but what I do not know is how to change the width of the others. Above are the three icons. The one on the far rights needs to be hidden on an iPod Touch, and the other two need to adjust size/ position to fill the remaining space. Any tips on programatically changing the position and width of a UIButton is greatly appreciated. Thanks!

  • SQL SERVER – Simple Example of Snapshot Isolation – Reduce the Blocking Transactions

    - by pinaldave
    To learn any technology and move to a more advanced level, it is very important to understand the fundamentals of the subject first. Today, we will be talking about something which has been quite introduced a long time ago but not properly explored when it comes to the isolation level. Snapshot Isolation was introduced in SQL Server in 2005. However, the reality is that there are still many software shops which are using the SQL Server 2000, and therefore cannot be able to maintain the Snapshot Isolation. Many software shops have upgraded to the later version of the SQL Server, but their respective developers have not spend enough time to upgrade themselves with the latest technology. “It works!” is a very common answer of many when they are asked about utilizing the new technology, instead of backward compatibility commands. In one of the recent consultation project, I had same experience when developers have “heard about it” but have no idea about snapshot isolation. They were thinking it is the same as Snapshot Replication – which is plain wrong. This is the same demo I am including here which I have created for them. In Snapshot Isolation, the updated row versions for each transaction are maintained in TempDB. Once a transaction has begun, it ignores all the newer rows inserted or updated in the table. Let us examine this example which shows the simple demonstration. This transaction works on optimistic concurrency model. Since reading a certain transaction does not block writing transaction, it also does not block the reading transaction, which reduced the blocking. First, enable database to work with Snapshot Isolation. Additionally, check the existing values in the table from HumanResources.Shift. ALTER DATABASE AdventureWorks SET ALLOW_SNAPSHOT_ISOLATION ON GO SELECT ModifiedDate FROM HumanResources.Shift GO Now, we will need two different sessions to prove this example. First Session: Set Transaction level isolation to snapshot and begin the transaction. Update the column “ModifiedDate” to today’s date. -- Session 1 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN UPDATE HumanResources.Shift SET ModifiedDate = GETDATE() GO Please note that we have not yet been committed to the transaction. Now, open the second session and run the following “SELECT” statement. Then, check the values of the table. Please pay attention on setting the Isolation level for the second one as “Snapshot” at the same time when we already start the transaction using BEGIN TRAN. -- Session 2 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that the values in the table are still original values. They have not been modified yet. Once again, go back to session 1 and begin the transaction. -- Session 1 COMMIT After that, go back to Session 2 and see the values of the table. -- Session 2 SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that the values are yet not changed and they are still the same old values which were there right in the beginning of the session. Now, let us commit the transaction in the session 2. Once committed, run the same SELECT statement once more and see what the result is. -- Session 2 COMMIT SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that it now reflects the new updated value. I hope that this example is clear enough as it would give you good idea how the Snapshot Isolation level works. There is much more to write about an extra level, READ_COMMITTED_SNAPSHOT, which we will be discussing in another post soon. If you wish to use this transaction’s Isolation level in your production database, I would appreciate your comments about their performance on your servers. I have included here the complete script used in this example for your quick reference. ALTER DATABASE AdventureWorks SET ALLOW_SNAPSHOT_ISOLATION ON GO SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 1 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN UPDATE HumanResources.Shift SET ModifiedDate = GETDATE() GO -- Session 2 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 1 COMMIT -- Session 2 SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 2 COMMIT SELECT ModifiedDate FROM HumanResources.Shift GO Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: Pinal Dave, SQL, SQL Authority, SQL Performance, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: Transaction Isolation
