• Virtual machine on ubuntu [closed]

  - by MITHIYA MOIZ

  I have configured virtual machine on ubuntu with the help of below article, https://help.ubuntu.com/9.04/serverguide/C/libvirt.html I managed to finish all the part except the major portion getting virtual host to talk to real network, Which I guess should be done only via bridge interface. Via virtual machine manager I try to choose any interface it gives me interface not bridged When I try to bridge the interceface eth0 as below auto br0 iface br0 inet static address 192.168.0.223 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.1 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off I cannot communicate with this interface to network, host server looses all the communication to network. But when I remote bridge interface from /etc/network/interfaces And configure eth0 as below it works fine The primary network interface auto eth0 iface eth0 inet static address 192.168.0.223 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 dns-nameservers 62.215.6.51 gateway 192.168.0.1 how can i setup bridge interface correctly and how would my /etc/netwrok/interfaces file would look a like.

• Complex jquery selction that also involves custom xml tags

  - by thecoshman

  I want to write a select something like... #window_4 > content > p:eq(0) I think I have this correct, but I have a few selectors that are all similar but I can't test them all at once. Am I right in saying this is selecting an element, who is the fist p tag child of a content tag that is a child of a tag with id 'window_4' If I have gotten this wrong, can you give me some pointers. Would love to be able to simplify this code, I have more code selecting the tag I am after then actually doing stuff with them.

• Drupal email users

  - by msindle

  I'm using Drupal 6.16: When a user creates an account on my site I have them select a category (ie children, youth, adult, etc). This is done with the select list box using the content_profile module. I have a content type that posts an announcement. In this content type is a check box that says 'email group'. Right now it does nothing, but what I would like for it to do is e-mail all the users that are associated with the group they chose when signing up for their account. If this will require extra code please be specific as I am not a strong php programmer. Thanks for the help!! msindle

• Getting field of type bytea in helper table when using GenerationType.IDENTITY

  - by dtrunk

  I'm creating my db scheme using Hibernate. There's a Table called "tbl_articles" and another one called "tbl_categories". To have a n-n relationship a helper table ("tbl_articles_categories") is needed. Here are all necessary Entities: @Entity @Table( name = "tbl_articles" ) public class Article implements Serializable { private static final long serialVersionUID = 1L; @Id @Column( nullable = false ) @GeneratedValue( strategy = GenerationType.IDENTITY ) private Integer id; // other fields... public Integer getId() { return id; } public void setId( Integer id ) { this.id = id; } // other fields... } @Entity @Table( name = "tbl_categories" ) public class Category implements Serializable { private static final long serialVersionUID = 1L; @Id @Column( nullable = false ) @GeneratedValue( strategy = GenerationType.IDENTITY ) private Integer id; // other fields public Integer getId() { return id; } public void setId( Integer id ) { this.id = id; } // other fields... } @Entity @Table( name = "tbl_articles_categories" ) @AssociationOverrides({ @AssociationOverride( name = "pk.article", joinColumns = @JoinColumn( name = "article_id" ) ), @AssociationOverride( name = "pk.category", joinColumns = @JoinColumn( name = "category_id" ) ) }) public class ArticleCategory { private ArticleCategoryPK pk = new ArticleCategoryPK(); public void setPk( ArticleCategoryPK pk ) { this.pk = pk; } @EmbeddedId public ArticleCategoryPK getPk() { return pk; } @Transient public Article getArticle() { return pk.getArticle(); } public void setArticle( Article article ) { pk.setArticle( article ); } @Transient public Category getCategory() { return pk.getCategory(); } public void setCategory( Category category ) { pk.setCategory( category ); } } @Embeddable public class ArticleCategoryPK implements Serializable { private static final long serialVersionUID = 1L; @ManyToOne @ForeignKey( name = "tbl_articles_categories_fkey_article_id" ) private Article article; @ManyToOne @ForeignKey( name = "tbl_articles_categories_fkey_category_id" ) private Category category; public ArticleCategoryPK( Article article, Category category ) { setArticle( article ); setCategory( category ); } public ArticleCategoryPK() { } public Article getArticle() { return article; } public void setArticle( Article article ) { this.article = article; } public Category getCategory() { return category; } public void setCategory( Category category ) { this.category = category; } } Now, I'm getting a serial type what I wanted in my articles table as well as in my categories table. But looking into my helper table, there aren't the expected fields article_id and category_id each of type integer - instead there are article and category of type bytea. What's wrong here? EDIT: Sorry, forgot to mention that I'm using PostgreSQL.

• Changing background image on accordion change - jQuery Ui

  - by Coughlin

  I am using this code: $('.ui-accordion').bind('accordionchange', function(event, ui) { $(this).next().next().css({'background-image':'images/green-bg.jpg'}); //ui.newHeader // jQuery object, activated header //ui.oldHeader // jQuery object, previous header // ui.newContent // jQuery object, activated content // ui.oldContent // jQuery object, previous content }); To try to change the background image of the PREVIOUS header after it changes. I see that the jquery docs supply the object for oldHeader, but I am trying to change the CSS of that element. Any ideas how I would do that? So You go to the next one it goes green, then the current one is going to be red. Thanks, Ryan

• NHibernate unable to create SessionFactory

  - by Tyler

  I'm having a bit of trouble setting up NHibernate, and I'm not too sure what the problem is exactly. I'm attempting to save a domain object to the database (Oracle 10g XE). However, I'm getting a TypeInitializationException while trying to create the ISessionFactory. Here is what my hibernate.cfg.xml looks like: <?xml version="1.0" encoding="utf-8"?> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" > <session-factory name="MyProject.DataAccess"> <property name="connection.driver_class">NHibernate.Driver.OracleClientDriver</property> <property name="connection.connection_string"> User ID=myid;Password=mypassword;Data Source=localhost </property> <property name="show_sql">true</property> <property name="dialect">NHibernate.Dialect.OracleDialect</property> <property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property> <mapping resource="MyProject/Domain/User.hbm.xml"/> </session-factory> </hibernate-configuration> I created a DAO which I will use to persist domain objects to the database. The DAO uses a HibernateUtil class that creates the SessionFactory. Both classes are in the DataAccess namespace along with the Hibernate configuration. This is where the exception is occuring. Here's that class: public class HibernateUtil { private static ISessionFactory SessionFactory = BuildSessionFactory(); private static ISessionFactory BuildSessionFactory() { try { // This seems to be where the problem occurs return new Configuration().Configure().BuildSessionFactory(); } catch (TypeInitializationException ex) { Console.WriteLine("Initial SessionFactory creation failed." + ex); throw new Exception("Unable to create SessionFactory."); } } public static ISessionFactory GetSessionFactory() { return SessionFactory; } } The DataAccess namespace references the NHibernate DLLs. This is virtually the same setup I've used with Hibernate in Java, so I'm not entirely sure what I'm doing wrong here. Any ideas? Edit The innermost exception is the following: "Could not find file 'C:\Users\Tyler\Documents\Visual Studio 2010\Projects\MyProject\MyProject\ConsoleApplication\bin\Debug\hibernate.cfg.xml'." ConsoleApplication contains the entry point where I've created a User object and am trying to persist it with my DAO. Why is it looking for the configuration file there? The actual persisting takes place in the DAO, which is in DataAccess. Also, when I add the configuration file to ConsoleApplication, it still does not find it.

• Implicit array casting in C#

• Wierdness debugging Visual Studio C++ 2008

  - by Jeff Dege

  I have a legacy C++ app, that in its most incarnation we've been building with makefiles and VS2003's command-line tool. I'm trying to get it to build using VS2008 and MsBuild. The build is working OK, but I'm getting errors where I'd never seen errors, before, and stepping through in VS2008's debugger only confuses me. The app links a number of static libraries, which fall into two categories: those that are part of the same application suite, and those that are shared between a number of application suites. Originally, I had a .csproj file for each static library, and two .sln files, one for the application suite (including the suite-specific libraries) and one for the non-suite-specific shared libraries. The shared libraries were included in the link, their projects were not included in the application suite .sln. The application instantiates an object from a class that is defined in one of the shared libraries. The class has a member object of a class that wraps a linked list. The constructor of the linked list class sets its "head" pointer to null. When I run the app, and try to add an element to the linked list, I get an error - the head pointer contains the value 0xCCCCCCCC. So I step through with the debugger. And see weirdness. When the current line in the debugger is in a source file belonging to the static library, the head pointer contains 0x00000000. When I step into the constructor, I can see the pointer being set to that value, and when I'm stepped into any other method of the class, I can see that the head pointer still contains 0x00000000. But when I step out into methods that are defined in the application suite .sln, it contains 0xCCCCCCCC. It's not like it's being overwritten. It changes back and forth depending upon which source file I am currently debugging. So I included the shared library's project in the application suite .sln, and now I see the head pointer containing 0xCCCCCCCC all the time. It looks like the constructor of the linked list class is not being called. So now, I'm entirely confused. Anyone have any ideas?

• IE7 is messing up the z-index property with my subnav (although I've already fixed that!)

  - by JAG2007

  OK, so I had this issue with my jQuery subnav in IE7 where it was scrolling down behind the main content after the header. Did a fair bit of research and found a great fix involving simply applying a z-index value to the header, and one to the main content. All was well. Or so I thought. Turns out IE7 is still messing up the subnav z-index within the header itself. The subnav still drops down behind the tagline, which is also part of the header. Particularly when you hit the subnav on the "Help Now" tab. (again, IE7 only) http://betawww.helpcurenow.org I've applied z-index values to both the subnav and the tagline, but that did not resolve the issue as did adding z-index values for the header and maincontent divs. Any tips? Did I specify my z-index improperly with the subnav? (should I have applied to the parent element?)

• iPhone webapp: my ressources don't get cached

  - by Savageman

  Hello, First of all, I'd like to say I'm not using any off-line feature from HTML5. I have a web-application which runs on the iPhone. When viewing it from safari, everything works quite well. But when I launch the application from the home screen (to remove the navigation bar), it can be really slow. I checked the logs in Apache and it appears that Safari does a good work to cache the resources (css / js / images), with Apache answering "304 Not Modified" when needed. However, when the web app run as a "real" application (navigation bar hidden), those resources doesn't get cached and Apache the content has to be transferred over and over again (response code 200 Ok + content), resulting in a significantly slower page load. How can I prevent this behavior? Do I need to always run my webapp inside Safari, even when it's launched from the home screen? Thank you!

• How do I construct a request for a WCF http post call?

  - by James Hay

  I have a really simple service that I'm messing about with defined by: [OperationContract] [WebInvoke(UriTemplate = "Review/{val}", RequestFormat = WebMessageFormat.Xml, Method = "POST", BodyStyle=WebMessageBodyStyle.Bare)] void SubmitReview(string val, UserReview review); UserReview is, at the moment, a class with no properties. All very basic. When I try and test this in Fiddler I get a bad request status (400) message.

  I have a long text and I'd like to offer the user a reading help: The current line should be highlighted. To make it easier, I'll just use the Y coordinate of the mouse (this way, the mouse pointer isn't going to get in the way). I have a big DIV with the id content which fills the whole width and a small DIV with the class content for the text (see here for an example). I'm using jQuery 1.4.

• Best practice to pass a value from pop up control on iPad.

  - by Tattat

  It is an iPad app based on SDK 3.2. I have a MainUIView, that is subclass from UIView, it have a UIButton and a UILabel. When user press the UIButton, the pop up control will be appeared with a table view. When the user select a cell from the table view, the UILabel changes content base on the user click, and the pop up table view will disappear. The question is, how can I pass the "selected cell" to the UILabel. I am thinking making a "middle man" object. When the user click the UIButton, and the "middle man" will pass to the table. When the cell is selected, the "middle man" will store the idx, and call the UILabel change content from the value of "middle man". But I think it is pretty complex to implement, is there any easier way to implement it? thz u.

• XSLT 1.0: Sorting by concating portions of date string

  - by dscl

  I'm trying to take XML data and sort elements by their data attribute. Unfortunately the dates come over in mm/dd/yyyy format and are not static lengths. (Jan = 1 instead of 01) So I believe the string will have to be parsed into three components and the month padded. The newly concated value (yyyymmdd) then sorted descending. Problem is I have no idea how to do this. Here is an example of the data <content date="1/13/2011 1:21:00 PM"> <collection vo="promotion"> <data vo="promotion" promotionid="64526" code="101P031" startdate="1/7/2011 12:00:00 AM"/> <data vo="promotion" promotionid="64646" code="101P026" startdate="2/19/2011 12:00:00 AM"/> <data vo="promotion" promotionid="64636" code="101P046" startdate="1/9/2011 12:00:00 AM"/> </collection> </content> Also can anyone please recommend a good book on learning XSLT? Thanks!

• C# Image.Clone to byte[] causes EDIT.COM to open on Windows XP

  - by JayDial

  It appears that cloning a Image and converting it to a byte array is causing EDIT.COM to open up on Windows XP machines. This does not happen on a Windows 7 machine. The application is a C# .NET 2.0 application. Does anyone have any idea why this may be happening? Here is my Image conversion code: public static byte[] CovertImageToByteArray(Image imageToConvert) { imageToConvert.Clone() as Image; if(clone == null) return null; imageToConvert.Dispose(); byte[] imageByteArray; using (MemoryStream ms = new MemoryStream()) { clone.Save(ms, clone.RawFormat); imageByteArray = ms.ToArray(); } return imageByteArray; } public static Image ConvertByteArrayToImage(byte[] imageByteArray, ImageFormat formatOfImage) { Image image; using ( MemoryStream ms = new MemoryStream(imageByteArray, 0, imageByteArray.Length)) { ms.Write(imageByteArray, 0, imageByteArray.Length); image = Image.FromStream(ms, true); } return image; } Thanks Justin
