re: PowerShell: Threading Enhancements FTW!

Great Article! I am trying to use it.

Inside a [ScriptBlock]:

1. How can I call the cmdlets (e.g Add-Item) without getting "Cannot invoke this function because the current host does not impl

ement it." error?

2. Can I load in assembly (like Microsoft.SqlServer.Smo) and use the objects in that assembly?

Thanks!

You need to use the Invoke-ThreadExpression function to put the function in the new thread (runspace).

Invoke-ThreadExpression $thread { function foo($bar) { echo "$bar!" } }

Set-ThreadVariable $thread "name" "PowerShell Rocks"Start-Thread -thread $thread { $value = foo $name } | Out-Null

How can I run a function asyncly? The code

$thread = Start-Thread {

& Myfunction 5

}

doesn't work. Help!

Yes, and I can't wait for RTM! Unfortunately, I needed threading now and couldn't use a CTP in production. :)

Have you had a look at the new *-PSJob and *-Runspace cmdlets in the V2.0 CTP2 drop?

To build on the threading library I mentioned here , I've added some functionality to make it easier

Try/Catch/Finally в PowerShell

PowerShell очень классный язык, но тем не менее очень молодой. И по этой причине в нём зачастую нет того чего хочется. Пока нет. Но так как он всё же очень классный - то чего нет можно дописать Вот к примеру если кому то не хватает привычной конструкции

You picked up on my, I'm not sure about this feeling, like all new things, gotta try it out, and yes, you could argue a simple one-line IF statement is easier to read. So, one thing I discovered was I moved the IsNullOrEmpty statement to an extension method so it became the above, Validator.ThrowIf(name.IsNullOrEmpty(), () => new ArgumentNullException("name"));

My biggest irk would be the one-line IF, I by standard always have something like that wrapped in squigglies and at minimum on four lines.

The idea was to have something like a WriteIf method but not allocating the object unless it was needed.
