• Why does LINQ-to-Entites recognize my custom method?

  - by BlueRaja The Green Unicorn

  This works: (from o in Entities.WorkOrderSet select o) .Where(MyCustomMethod); This does not: (from o in Entities.WorkOrderSet select new { WorkOrder = o }) .Where(o => MyCustomMethod(o.WorkOrder); I understand why the second doesn't work - but why in the world does the first work!? Shouldn't I get a "custom method not recognized?" For reference, here is MyCustomMethod public bool MyCustomMethod(WorkOrder workOrder) { return !workOrder.WorkOrderNum.StartsWith("A", StringComparison.CurrentCultureIgnoreCase); }

• What is the preferred method of refreshing a combo box when the data changes?

  - by Craig Johnston

  What is the preferred method of refreshing a combo box when the data changes? If a form is open and the combo box data is already loaded, how do you refresh the contents of the combo box without the form having to be closed and reloaded? Do you have to do something on the Click event on the combo box? This would seem to be a potential slow down for the app if there is a hit to the database every time someone clicks on a combo box.

• What is the meaning of method class in the class definition in Ruby?

  - by Steven Xu

  I'm familiar with function definitions and variable declarations being in class definitions: public class MyClass { public int myvar; public void doSomething() { } } But what does it "mean" in Ruby when a method is actually called in the class definition? This happens amply in Rails, for instance: class User < ActiveRecord::Base has_many :posts end What exactly does this do (at a lower level than "it adds some methods to the class")? How would I implement such a function (e.g., one that mixes in some additional methods)?
