How do I convert an IEnumerable(Of CheckingAccount) into an IEnumerable(Of Account) ? (where CheckingAccount inherits from Account).Currently this conversion isn't allowed, but we're considering a VB language feature to support it. The topic is called "co- and contravariance", and has been in the CLR since 2005 or so, but no one's yet released a .N...

Today I posted an interview screencast on Channel 9. In this interview, Jared Parsons, a Developer on the Visual Basic IDE, shows us the P/Invoke Interop Assistant available on CodePlex. The tool helps with converting unmanaged C code to managed P/Invoke signatures and vice versa. Say goodbye to digging through random header fil...

Last month when I was in Redmond I was pulled into a photo with some of the people working on Visual Basic. Do you notice something quirky about these pictures (besides me)? Yes, they are all wearing grey shirts! There's apparently a running joke going on with how Jonathan Aneja (top row, 4th from the left in the first picture) only wears grey. So ...

In the July/August issue of CoDe Magazine there's an article I wrote with Avner Aharoni (the Program Manager on XML literals) called Sharpening Your Axis with Visual Basic 9. (They just opened up online access to even non-subscribers today!) I highly recommend this article which shows you from the beginning how XML literals, embedded expressio...

I'm happy to announce that the PInvoke Interop Assistant tool is now available on CodePlex.  This includes the binaries, source code and the dev authored unit tests.  It is hosted on the more general CLR Interop Tools page.  http://www.codeplex.com/clrinterop I will be actively maintaining this tool in the future and (hopefully) addi...

In yesterday’s blog post, I walked through an engine for translating DNA to its amino acid results via messenger RNA.  In today’s blog, we’ll work on the visualization using WPF StackPanels.  (This example requires VS2008, although it could certainly be written in WinForms as well with just a little bit of extra work.)Ca...
