  I am stuck on how to pass data from one control to another. If I have a listbox control and the Contol Item contains a datatemplate which renders out 5 fields ( first name, last name, email, phone and DOB) all of which come from an observable collection. How can I allow the user to select a listbox item and have the valuesbe stored within a new listbox control? Is this done through the creation of a new collection or is there a more simple way to bind these values to a new control? thank you,

• Is passing a struct value to a method by-reference in C# an acceptable optimization?

  - by Arc

  Say I have a struct: struct MyStruct { public int X public int Y } And a method in some class that is iterated over many times elsewhere: public bool MyMethod( MyStruct myStruct ) { return ... } Is changing the MyMethod signature to the following an acceptable optimization? public bool MyMethod( ref MyStruct myStruct ) If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?

• Need help with text animation within UITableViewCell

  - by gdiphone

  I'm trying to implement a simple text animation in a custom UITableViewCell without having to go into editing mode which automatically brings up the delete button on the right. What I'm trying to accomplish is that when the label is updated by a button within the UITableviewcell, the text in the label is updated but with some smooth animation like sliding to the right since the updated text is prepended to the string. Any sample code would be great. thanks

  Do any Silverlight APIs exist to facilitate development of a custom browser-based diagramming app? It seems a shame to build something from scratch with shape primitives (such as this example), but I've searched Google and can't find much.

• What happens on a JMS queue when onMessage() throws a JMSException?

  - by user311121

  Hi, I'm using Spring 2.5 with my custom class that implements MessageListener. If a JmsException is thrown in my onMessage( ) method, what happens to the state of the queue? Is the message considered "delivered" by the queue the moment onMessage is called? Or does the JmsException trigger some kind of rollback and the message is re-entered on the queue? Thanks in advance!

• @Unique doesn't have any effect in DataNucleus w/ NeoDatis

  - by David Parks

  Using JDO / DataNucleus / NeoDatis datastore I added @Unique to a field of a persistable object, however I am allowed to create multiple objects which violate the unique constraint. The docs for DataNucleus/NeoDatis suggest that Unique fields are supported. @PersistenceCapable public class User { @Persistent @Unique private String username; //... } If I add multiple objects to the DB with the same username there's no problem doing so. :(

• When would I want to model a class with a private ctor?

  - by dotnetdev

  Hi, I've seen plenty of classes in .NET which have private constructor (Stream is one of them I think). When would I want to model a class like this? I keep thinking that if my class has no internal state/fields, then I can make it have a private constructor. Am I on the right track with this idea? I can understand the use of a factory (I've run into the tipping point a few times), but not with a private constructor class. Thanks
