start System.Threading.Thread

[Selko]

Hy group!

I have created a gui form with some functions. When i start a function which
lasts longer the gui freezes and cant write out any text to the gui until the
function has finished

now i need System.Threading.Thread

but how can i start a thread from powershell
i have tried it so:

function test{
do something....
}
$start=new-object Threading.ThreadStart(test)
$thread=new-object System.Threading.Thread($start)

but this doesnt work

can you help me please?
thank you

From what I understand, default PowerShell must run Windows forms in a
single thread, so what you're trying just won't work with v.1 anyways...

I don't *think* that's it... I think the issue is that you're trying to
use this within a Windows form.

I'm going to go quiet on this now because this is beyond what I know
today...

There's some interesting blog posts and scripts out there about creating
job pools and background tasks. I don't know if any of them apply to
what you are trying to do however.

AFAIK you cannot... you can use runspaces as illustrated here

Hi there,

Suffice it to say, given the tools Powershell v1.0 provides you, this
cannot be done in any elegant or practical fashion. In technical
terms, Windows Forms instances demand a COM threading model of STA,
and demand thread affinity. Powershell employs the very opposite
model, it being multithreaded with an MTA apartment model.

Having said this, I'd keep an eye out for some cmdlets or tools that
will let you do this in the future, as it's not impossible,
technically speaking ;-)

After much futzing around I was finally able to start .NET threads in Powershell 2.0. This isn't a Winform script though, but I believe you could get that to work by makeing the new thread STA. Note that write-host (and friends) don't work because the PS host created with the Powershell() method doesn't have support.

# If it works you'll see notepad start
$s= ( notepad from_thread )
$ps_s=$s.GetPowerShell()
$smi=($ps_s.gettype().getmethods()| ? {
$_.name -eq "Invoke"})[0]
$fp = $smi.methodhandle.getfunctionpointer()
$ts=new threading.threadstart $ps_s,$fp
$thr = new threading.thread $ts
$thr.start()
