Hopefully you already know VB has full support for Optional parameters, both declaring them and calling them, but did you know you can use Dates as Optional parameters ? Public Sub AddNewCustomer(customer As Customer , ...
From time to time there’s discussion about the way dates are displayed in the Visual Studio IDE for Visual Basic. Typically dates are shown using VB’s date literal syntax of #MM/dd/yyyy# which is the standard US format. For people outside...
The Silverlight Windows Phone Toolkit August 2011 (7.1 SDK) doesn't contain a working VB sample. If you try to load the VB sample that does ship, you’ll get hundreds of errors. So I put together the VB sample that should have shipped....
In the emulator in the tools SDK that is Still waiting on the actual phone update, but for developers the tools update is now available from: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=49b9d0c5-6597-4313-912a-f0cca9c7d277&displaylang...
This seems so incredibly long overdue, but at last as of .NET 4, IntPtr has + and – operators added to it !! This means you can now easily write code such as : Dim ptr As IntPtr . . . . ptr += 4...
A couple of months ago I blogged about iterators in VB (or the lack there-of), and pointed folks to an article I wrote for Visual Studio magazine that provides snippets and templates to help with iterators in VB . One of the things I talk about in that...
Back in April 2006, I blogged about a nasty JIT compiler optimisation that would cause String.IsNullOrEmpty to throw a null reference exception; ironic really given that is the very thing you’d use the IsNullOrEmpty method to check against. ...
I’ve just uploaded a new screen cast: Snippet Editor Tips and Tricks Enjoy :) (oh and don’t forget the “ buy me a beer ” button)
Snippet Editor 2.1 is now released on codeplex: http://www.codeplex.com/SnippetEditor Apart from the few minor bug fixes, it includes improved search and now support for Visual Studio 2010 as well as 2008 and 2005. I’ve also added a “buy me a beer...
Although VB 10 won’t have a formal syntax for iterators, it will have all the necessary ingredients to easily write iterators. In VB10 you can use a generic template and multi line lambdas to create iterators. This iterator in C# : static public...
I’ve just finished uploading the Snippet Editor to CodePlex http://www.codeplex.com/SnippetEditor It includes some minor bug fixes from the previous release. Enjoy :) And Merry XMas :)
Over the last week I’ve got a sudden influx of emails about the Snippet Editor. I’m figuring this is stemming from Lisa’s recent blog entry and her tips and trips for VS 2008 presentation :) Some of the emails have been really nice praise...
To answer what is in VB 10, have a look at the document on the vb futures site . Basically the list is removal for the need of the line continuation character in many places, collection and array initializers, multi statement lambdas, and generic...
Davy Brion posted about how events can keep object references alive. In C# to rid yourself of this issue you have to manually unwire any event handler you wired. In VB, it is a lot easier, all you have to do is use WithEvents and set the variable...
Lucian has kicked off the conversation on generic variance in VB , so I thought I’d write a few posts outlining my perspectives on the subject… the first of which is this one, and what better place to start than to question whether or not it is really...
It seems apparent that with computers as we currently know them, processors are now set to scale out not up.. that is, clock speeds aren’t rapidly growing, and certainly not doubling every year or two, instead the number of processors on a chip is. ...
I was reading Kathleen’s post about what a C# developer needs to know about VB and thought I should clarify the bit about Booleans converted to numerics. A Boolean in VB when converted to an integer type numeric, will be zero or the bitwise Not...
Does VB need prefix and postfix increment and decrement operators ? Here's an example I posted today for a question on adding an index with LINQ: Sub Main() Dim values() As String = { "aaa" , "bbb" , "ccc" } Dim index...
After my post about the first set of insults from the Windows Live team and the Search API samples, it was nice to see some VB samples released. Sadly though they were just the C# samples run through an automated tool. I mean look at this bullshit code...
Kudos to Charlie Calvert for opening up the discussion of C# future features to the public (sure would be nice if the VB team did likewise). In the first post on future features , Charlie talks about dynamic lookups in C# .... Although the catchy term...
