Often I want to store the results of a cmdlet in a variable for additional processing. Usually I do something like this:$myProcesses=get-processAn alternative is to use one of the common paramaters, -OutVariable.
Make-A-Cmdlet: Part 6, Wrapup
Okay, in my cmdlet code, you’ll notice that I used WMI – albeit in a very .NET-esque fashion – to ping a remote computer.

PowerQuest Finds a Home on the Web
PowerQuest (you know, my new hobby of making Windows PowerShell less productive by making a game snap-in) has found a home on Microsoft’s CodePlex. Since this really is just a hobby, I wanted to be able to share the source code and everything, and CodePlex is all set up to do that. Well, mostly; I have the current binary DLL posted …
