• compiling a linq to sql query

  - by frenchie

  Hi, I have queries that are built like this: public static List<MyObjectModel> GetData (int MyParam) { using (DataModel MyModelDC = new DataModel()) { var MyQuery = from.... select MyObjectModel { ...} } return new List<MyObjectModel> (MyQuery) } } It seems that using compiled linq-to-sql queries are about as fast as stored procedures and so the goal is to convert these queries into compiled queries. What's the syntax for this? Thanks.

• Behaviour difference Dim oDialog1 as Dialog1 = New Dialog1 VS Dim oDialog1 as Dialog1 = Dialog1

  - by user472722

  VB.Net 2005 I have a now closed Dialog1. To get information from the Dialog1 from within a module I need to use Dim oDialog1 as Dialog1 = New Dialog1. VB.Net 2008 I have a still open Dialog1. To get information from the Dialog1 from within a module I need to use Dim oDialog1 as Dialog1 = Dialog1. VB.Net 2005 does not compile using Dim oDialog1 as Dialog1 = Dialog1 and insists on NEW What is going on and why do I need the different initialisation syntax?

• How to change aif to be able to access 'it' within the macrocall without making 'it' public in the package

  - by Sim

  If you put the aif code presented in onlisp in a package and try to use it in another you run in the problem that packagename:it is not external. (in-package :packagename) (defmacro aif (test-form then-form &optional else-form) ‘(let ((it ,test-form)) (if it ,then-form ,else-form))) wanted call syntax (in-package :otherpackage) (aif (do-stuff) (FORMAT t "~a~%" it) (FORMAT t "just got nil~%")) How can I fix this behavior in code, without making the variable it external in the package declaration and beeing able to access it just by it instead of packagename:it?

• What programming languages are good for statistics?

  - by Jason Baker

  I'm doing a bit more statistical analysis on some things lately, and I'm curious if there are any programming languages that are particularly good for this purpose. I know about R, but I'd kind of prefer something a bit more general-purpose (or is R pretty general-purpose?). What suggestions do you guys have? Are there any languages out there whose syntax/semantics are particularly oriented towards this? Or are there any languages that have exceptionally good libraries?

• Way to partialy match a Ruby string using Regexp

  - by Fabiano PS

  I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

I could not get let-syntax to provide the same functionality. Currently I use plt scheme, but would like to see answers in different lisp implementations as well.

• Why cast null before checking if object is equal to null?

  - by jacerhea

  I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

  Hi, I have a list of records that all need their individual TTLs modified. I can't seem to find a way with this odd syntax to do so, however. Any recommendations?
