This may be more of an OOP concept question, but here's what I'd like to do. I have an application that outputs debug information using System.Diagnostics.Trace.WriteLine so it can be viewed with DebugView. I'd like to override/extend (not sure of the proper terminology) this method to log the text to a file instead, or maybe in additi...

I mean, does time increase as O(1), O(log n), O(n) when n goes to be large, or in some other way? Dim index As New Dictionary(Of String, SomeReferenceType) ' N entries added in a loop ' ... D...
In C#, when writing a function that returns an IEnumerble<>, you can use yield return to return a single item of the enumeration and yield break; to signify no remaining items. What is the VB.NET syntax for doing the same thing? An example from the NerdDinner code: public IEnumerable<RuleViolation> GetRuleViolations() { if (String...

I created an extension method to convert an integer to the corresponding month it is associated with. I tested the extension method in a console application so I know it is working. In my asp.net mvc project I have a view and want to...
Is there any way to select items in a list that aren't contained in another? For example: list1 = From t In list1 Where Not list2.Contains(t.column1) That gives me the error: Value of type 'Integer' cannot be converted to '<anonymous type>' which makes sense, since list2.Contains is expecting the same type as list2. However, the li...

The intent is to block them from accessing "open" or "open with" and only allow them to pick a file from the list. My only other idea is to build my own control instead ...
