• How to identify whether the objects are just reference or just copied? .net Memory Management

  - by NLV

  Hello I'm confused to find whether an object is either copied or the reference of the object is held while equating it to some other objects. Examples int i =5; int j = i; Reference or copy of data? DataSet ds = dsOtherDataSet.Copy(); Reference or copy of data? DataView dvTemp = dsTestDataSet.Copy().DefaultView; What happens here? Regards NLV

• Dojo and unregistering widgets

  - by John Korsnes

  Hi, I am new to the Dojo Toolkit. I'm getting the error Tried to register widget with id=myButton but that id is already registered whenever I try to load dojo content twice (meaning I load HTML content through jQuery.Load into a container div). Is there a way of unregistering already registered widgets in dojo? I've seen some examples, but I don't really get them working. My button: <button dojoType="dijit.form.Button" id="myButton">button</button>

• Has the `message-passing/shared-state' dilemma (concurrency & distribution) taken form of a `Holywar

  - by Bubba88

  I'm not too well-informed about the state of the discussion about which model is better, so I would like to ask a pretty straight question: Does it look like two opposing views having really heatened dispute? E.g. like prototype/class based OOP or dynamic vs. static typing (though these are really not much fitting examples, I just do not know how to express my question more clearly)

• Most inappropriate function or variable names you have encountered?

  - by Andrioid

  I was reading through my daily doze of RSS when I noticed a link to the python compiler documentation where class names like assList, assName and assTuple exist. While starting names with 'ass' is perfectly acceptable to me, it just sparked this idea that there probably exist much better examples of this. Have you personally used or otherwise encountered any inappropriate function or variable names? Personally I have used 'crap' and 'moo' for temporary purposes, forgot them and at a later point they came too integrated for me to bother with fixing them.

• How to get width of button in DateTimePicker-Control/Controls in general?

  - by Inno

  Hello everybody, I implemented a custom DateTimePicker. On the DateTimePicker there is a button. In the examples I've found it's width is set to 16. This is working but I would like to have a dynamic approach. So, is there a way to get the size of this button or is there a general way to get information about .Net-Control sub elements like size etc.? Trying DateTimePicker.Controls didn't help me (it's empty).

• Ruby (and Rails) nested module syntax

  - by brad

  I'm wondering what the difference is between the following two modules # First Example module Parent module Child end end and # Second Example module Parent::Child end Using the 2nd method, it appears as though the Parent module must be previously defined, otherwise I get an 'uninitialized constant' error Given this, what is the preferred way of defining modules such as this and then adding nested children with regards to syntax and file structure (ie. folders etc). Reference to a Rails way would be greatly appreciated. Are these two examples for all intents and purposes equivalent?

• Concatenative language inrepreter in Java

  - by Vojislav Stojkovic

  I'm interested in finding a concatenative language interpreter in Java. Ideally, it should satisfy the following conditions: It has an interpreter, not (only) a bytecode compiler for JVM. The language itself has decent documentation, not only a few examples and a "I'll document the rest someday" notice. The project is not completely abandoned. In short, I'm looking for a reasonably "alive" concatenative language that can be embedded into Java easily.

  I'm putting together a Solution Architecture document for an enhancement we're adding to our site and it occurs to me that I've never formally illustrated a web service call before. Is there a convention for how web service calls are illustrated on your garden-variety network diagram? Can anyone point me to examples or share something on Create.ly (or similar service)?
