Hide console and capture output from script?

I'm trying to figure out how to go about launching a command-line exe
from a Powershell script while capturing its output and not showing
the command window.

I currently have:

$result = (Invoke-Expression "c:\myconsoleapp.exe -param $myparam")
"The result is: $result"


While this works, a new window pops up for myconsoleapp.exe. Is there
a way to prevent this and just capture the out?

Not sure you can - you are invoking cmd.exe to run your console app & I can't
see a way to run it without the window

Maybe you could create a runspace and run the exe from it and get the
output.

Unless myconsoleapp.exe explicitly creates a new console window, it should
just inherit the current console window. Does this behavior happen only
from PowerShell?

If I just launch a shell and type in the program name and parameters
neither CMD nor Powershell launch a new window. It only occurs when
launched via Invoke-Expression in my script that it launches a new
window.
