The other week, I showed a Get-ProgID function that I used to help someone at Microsoft Research find a good object to talk to images.  A few comments jumped to one of the possible solutions, which is to use the .NET Drawing assembly (which I have to load first).  I wanted to be reasonably sure that the way to get at the image ...

Have you ever created scriptblocks on the fly, say in a foreach loop, and they totally mess up because they all have the same value? This is something sort of advanced, and typically used when you’re proxying an object. The most basic example would be, taken from (http://www.powershellcommunity.org/Forums/tabid/54/aff/1/aft/2506/afv/topic/...

Everyone needs to get good with Advanced Functions – this is the easiest path to the best semantics for everyone.  In previous posts we’ve shown how you can add a few simple attributes and get a TON of stuff for free.  There is a LOT more to advanced functions.  You can go VERY VERY far with advanced functions.  I can...

I started using Twitter and saw a request from Thomas Lee for help about pipelining in CTP3.  The thing about Twitter is that the messages have to be tiny so I wasn’t sure I could answer using it.  It turns out I can solve this problem AND give a usage example in 73 characters.  Here goes: PS> function t{param([Parameter(...

If you're like me, you've got a browser favorites folder that is full of wonderful PowerShell code snippets. Ideally, it would be great to have a way to bring those favorite snippets into PowerShell so that my favorites folder becomes a code library. Doing this presents several challenges. The first (and easiest to solve) is getting the web ...

On my personal blog (Media And Microcode), I've been posting a series called "Scripting the Web", which introduced a function called Get-MarkupTag. Get-MarkupTag is a very handy little function that coerces individual tag elements of a web page into HTML, so you can scrape data from a webpage. I've updated Get-MarkupTag a tiny bit ...

Welcome to CTP3!  There are just an amazing amount of really important features in V2 but the one I want everyone to start using ASAP is Advanced Functions.  In CTP2 we called this cmdlets.  We dropped that term in favor of taking the idea of a FUNCTION and just making it more and more capable.  It is a bit of a misnomer in...

Tyson Kopczynski has just published a great article Fun with PowerShell 2.0 Eventing!  That inspired to to write a script to automatically backup my modules directory.  I'm doing a lot of scripting this week and I don't want to lose my work if I make a mistake.  I thought I would write a scripting using PowerShell 2.0 Eventing ...
