  • How can I cancel Drag and Drop operation in Java/Swing programmatically?

    - by AlexV
    I am just wondering if it's possible to I cancel "Drag and Drop" operation in Java/Swing programmatically? So the effect would be similar to if the user pressed the "ESC" key? I was expecting DragSourceDragEvent or DragSourceContext to have a cancelDrag() method, similar to DropTargetDragEvent which has acceptDrag() and rejectDrag() methods (both of which does not do what I want). I am missing something?

  • Built-in precedence for Expression Trees?

    - by jdk
    I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it, maybe through helper methods or classes? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.

  • Advanced count and join in Rails

    - by trobrock
    I am try to find the top n number of categories as they relate to articles, there is a habtm relationship set up between the two.

  • How to achieve table like rows within container using CSS

    - by Barry
    I'm helping an artist maintain her website and have inherited some pretty outdated code. Have moved lots of redundant common code to include files and am now working on moving from inline styles to more CSS-driven styles. For the gallery pages, e.g. http://artistsatlaketahoe.com/abstract.html, a lot of inline styling is used to force the current layout. My preference would be to replace this entirely with CSS that presents the following table-like layout within the "content" div: [image] [image descriptives and purchase button] [image] [image descriptives and purchase button] [image] [image descriptives and purchase button] I'd like to middle-align the image descriptives & purchase button relative to the image if possible. And then apply some padding above and below each row to stop using tags for vertical spacing. Any ideas how to create a div that I can use to get this kind of layout? Thanks!

  • How can I see the parameters in intellisense in a spark file?

    - by kjm
    Hi, I've got spark intellisense working but when I open the parameters () of the method I can not see what is supposed to go in there and several of the methods have overloads so I can't see what options I have. For example !{Html.Hidden()} once I open the () I can not see what parameters I am to pass any ideas?

  • Use delegate for Projection in Linq to SQL

    - by Redeemed1
    I have code something like this in an IRepository implementation in Linq to Sql: var newlist = from h in list where h.StringProp1 == "1" select new MyBusinessBO{ firstProp = h.StringProp1, secondProp = h.StringProp2 }; The projection into MyBusinessBO is not difificult but when the Business Object has many properties the projection code becomes very lengthy. Also, as the projection can occur in several places in the Repository we break the DRY principle. Is there any way to abstract out the projection or replace it with a delegate? I.e. replace the code firstProp = h.StringProp1, secondProp = h.StringProp2 with something reusable?

If ASP.net is not up to the task, other languages or free scripts/toolkits would be acceptable. Thanks.

  • Does Hibernate always need a setter when there is a getter?

    - by Marcus
    We have some Hibernate getter methods annotated with both @Column and @Basic. We get an exception if we don't have the corresponding setter. Why is this? In our case we are deriving the value returned from the getter (to get stored in the DB) and the setter has no functional purpose. So we just have an empty method to get around the error condition..

  • How can I make a single WCF method ConcurrencyMode.Multiple when service is ConcurencyMode.Single

    - by Michael Hedgpeth
    I have a service which is defined as ConcurrencyMode.Single: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, UseSynchronizationContext = false, InstanceContextMode = InstanceContextMode.PerSession, IncludeExceptionDetailInFaults = true)] public class MyService : IMyService This service provides a method to tell the client what it's currently working on: [OperationContract] string GetCurrentTaskDescription(); Is there a way to make this particular method allowable while another long-running task is running where all other methods still follow the single-threaded concurrency model?

  • UIAlertViewDelegate clickedButtonAtIndex: usefulness?

    - by Ed Marty
    The UIAlertViewDelegate protocol defines two methods, alertView:clickedButtonAtIndex: and alertView:didDismissWithButtonIndex:, which seem to me to be identical in usefulness. Why is there a clickedButtonAtIndex and a didDismissButtonWithIndex when they both do the same thing? I realize there is also a willDismissButtonWithIndex that happens before the alert view is dismissed, but is there any reason to use clickedButtonAtIndex instead of didDismissButtonWithIndex?

    - by William Jockusch
    Suppose we are writing a class (let's call it Class) in an iPhone program. In all the samples out there, the init methods are typically declared like this: -(id) initWithFoo: (Foo *) foo My question is: would it be more logical to do the following? Why or why not? -(Class *) initWithFoo: (Foo *) foo

  • AS3 - Tile image/movieclip along a line

    - by Mim Hufford
    If possible I would like to tile an image or MovieClip along a line using the standard moveTo() and lineTo() methods, The lines are directional so need to show something similar to >>>>>>>>>>>>>. The lines can be at any angle, so using drawRect() with beginBitmapFill() isn't an option. Also if possible I would like to have the lines animated. Is this possible or will it require a custom class?

  • Calling pthread_cond_signal without locking mutex

    - by Maysam
    Hi, I read somewhere that we should lock the mutex before calling pthread_cond_signal and unlock the mutext after calling it: The pthread_cond_signal() routine is used to signal (or wake up) another thread which is waiting on the condition variable. It should be called after mutex is locked, and must unlock mutex in order for pthread_cond_wait() routine to complete. My question is: isn't it OK to call pthread_cond_signal or pthread_cond_broadcast methods without locking the mutex?

  • JavaScript method to write to Microsoft Visual Web Developer Debugger?

    - by Josh
    I generally test my web apps with Firefox and use Firebug. I love Firebug. But when I'm testing JavaScript code in IE I use the debugger in Microsoft's Visual Web Developer 2008 Express Edition. I would love to have an equivalent to Firebug's console.log methods which would allow me to log messages to Visual Web Developer. Any way to log messages to the error list/messages list/output pane using JavaScript?

  • Java/JAXB: Unmarshall Xml to specific subclass based on an attribute

    - by Frothy
    Is it possible to use JAXB to unmarshall xml to a specific Java class based on an attribute of the xml? <shapes> <shape type="square" points="4" square-specific-attribute="foo" /> <shape type="triangle" points="3" triangle-specific-attribute="bar" /> </shapes> I would like to have a List of Shape objects containing a triangle and a square, each with their own shape-specific attribute. IE: abstract class Shape { int points; //...etc } class Square extends Shape { String square-specific-attribute; //...etc } class Triangle extends Shape { String triangle-specific-attribute; //...etc } I'm currently just putting all attributes in one big "Shape" class and it's less than ideal. I could get this to work if the shapes were properly named xml elements, but unfortunately I don't have control of the xml I'm retrieving. Thanks!
