Useful Scripting objects

$psUnsupportedConsoleApplications

There are some limitations on how Windows PowerShell ISE interacts with console applications. A command or an automation script that requires user intervention might not work the way it works from the Windows PowerShell console. You might want to block these commands or scripts from running in the Windows PowerShell ISE Command pane. The $psUnsupportedConsoleApplications object keeps a list of such commands. If you try to run the commands in this list, you get a message that they are not supported. The following script adds an entry to the list.

# List the unsupported commands
psUnsupportedConsoleApplications
# Add a command to this list
psUnsupportedConsoleApplications.Add(“Mycommand”)
#Show the augmented list of commands
psUnsupportedConsoleApplications
