Next week I will be speaking at Dev Connections in Las Vegas. I will be running the following sessions VMS02: Future Directions for Visual Basic VMS04: Microsoft Visual Basic IDE Tips and Tricks Both of these talks will spend a bit of time talking

As the owner of the VB.Net portion of the overall debugging experience, I frequently hear the request from customers to add LINQ support into the Watch / Immediate and Locals window. Virtually every other type of expression is available in the debugger

One of the seldom used, and often unknown, features of VB extension methods is that the argument of the extension method (the first parameter) can be passed by reference. This gives extension methods the power to change the reference that was used

The WinForms Timer class allows the user to perform a particular action at a set interval. Timer objects fire a Tick event at the set time which users can easily respond to. This is very useful if a developer wants to check for a particular

The VB Catch syntax has a particular feature not present in C#: When. It allows users to filter expressions based on something other than their type. Any arbitrary code can enter a When block to decide whether or not to handle an Exception Sub Sub1()

The August issue of MSDN magazine will be carrying an article I wrote this spring. In it I toy around with using the deferred execution and lazy evaluation properties of LINQ to create more responsive UI code. You can view the article here

Recently I've done a bit of posting about the difficulties of properly implementing equality in VB (and DotNet in general). While most of the problems can be fixed with a standard snippet the one really hard to implement issue is GetHashCode(). The rules

After my recent postings on the rules of Equality , I thought it would be a good idea to post a simple example of equality. The class in question, Example, has only one field of type Integer name m_field1. Two instances of Example are equal if m_field1

This is a bit of a follow up to a previous post we discussed how to properly implement equality in VB. Several users commented/asked that IEquatable(Of T) could be used in place of overriding Equals(). Since IEquatable(Of T) doesn't define a GetHashCode()

Many developers want to implement equality functions for their objects. DotNet made equality a deep part of the framework and added support all the way up to System.Object with Equals and GetHashCode . In addition to the strongly enforced

Recently we had a good discussion on an internal alias about the use of Me, MyClass and MyBase in VB. Me, MyBase and MyClass are all ways to access instance member data in a VB class or structure. There was a little bit of confusion on the actual workings

Previously I discussed a potential missing API in List(Of T).BinaryInsert. One of the items I mentioned was it had better performance because it was O(Log N) vs Insert and Sort which is O(NLogN). Several users correctly pointed out this was incorrect

IComparable(Of T) is an interface saying "I can compare myself to other objects of the same type". And IComparer(Of T) is an interface saying "I can compare two objects of this type.". Often API's which need to perform

One API that seems to be missing from List(Of T) is a BinaryInsert method. Especially since there is already a BinarySearch method. Binary insert is a method for inserting a value into an already sorted list. Since the list is already sorted

Besides waiting, the another important issue when dealing with Futures is how to deal with exceptions thrown by the user specified code. Option 1: Ignore the Exception Don't take any actions in the future code and force users to write exception
