A group blog from members of the VB team
January 26, 2010Jan 26, 201001/26/10One of the overlooked or simply misunderstood features of the VB language is calling a function which has a ByRef parameter. Most languages support only a single method of passing parameters by reference [1], that is the scenarios directly supported by the CLR.
October 15, 2008Oct 15, 200810/15/08Here’s another community interview from our Italian Visual Basic MVP Alessandro Del Sole, this time with Jared Parsons, a Developer on the VB Team. Jared is a great developer and loves the community. You can check out his personal blog here.
October 9, 2008Oct 9, 200810/9/08The VB Catch syntax has a unique feature: 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.
1 2 3 4 5 6 7 8 | <span>Sub </span>Sub1() <span>Try </span>DoSomeAction() <span>Catch </span>ex <span>As </span>Exception <span>When </span>Filter(ex) <span>Stop End Try End Sub </span> |
Newsgroups often ask,
July 28, 2008Jul 28, 200807/28/08Today 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.
June 20, 2008Jun 20, 200806/20/08I’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.

I will be actively maintaining this tool in the future and (hopefully) adding more features.
March 14, 2008Mar 14, 200803/14/08Jared here again.
I very excited to announce we recently released a tool I’ve been working on to MSDN that will greatly help with using PInvoke in managed code. The tool is called the “PInvoke Interop Assistant” and is included as part of a MSDN article on marshalling data for PInvoke and Reverse PInvoke scenarios.
September 28, 2007Sep 28, 200709/28/07We’ve heard feedback from several customers regarding the way certain types are displayed in the Debugger. Many of the displays exist to maintain the user experience between versions of Visual Studio. We constantly evaluate if this is the correct choice for a given version of the product.

Once again sorry for the long delay between posts.
Looping structures can cause unintended consequences when used with Lambda expressions.

Sorry for the long delay between posts here. We’re getting Orcas out the door and getting this series completed takes a back seat to shipping.

Thus far in the series we’ve only lifted variables that are declared in the same block/scope. What happens if we lift variables in different scope?
