Powershell and COM objects

The code below stops service. 

$comAdmin = New-Object -com ("COMAdmin.COMAdminCatalog.1")
$comAdmin.ShutdownApplication("US Business Objects")

Open in new window


What would the code be to check status of COM object before and after I stop service?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The specific COM object implements status members. Aside from "does the object exist" (the result not being $null or an empty object), there is nothing generic you can check.
Leo TorresSQL DeveloperAuthor Commented:
OK so there is no way to check is COM object is running or not?
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
No. If you get an object, the process hosting the object is running - necessarily. If the object can check for the status of other processes, it is different, and that might be what you are after. I'll check the COM object you use to see if I can find out more.

Mind you the "US Business Objects" i am using is an internal object your going to have to use another Object.
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
In a quick glance, going thru all COM app instances, and checking for the GUID matching, is the only way to check if all instances are shut down (see http://www.31a2ba2a-b718-11dc-8314-0800200c9a66.com/2008/11/shutting-down-running-com-instance_9879.html for non-PS example code).
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
Can't test, as I don't have any COM object available in the factory, so I'll have to provide something for you to test:
$comAdmin = New-Object -com ("COMAdmin.COMAdminCatalog.1")
# $comAdmin.ShutdownApplication("US Business Objects")

$instances = $comAdmin.GetCollection("ApplicationInstances")
$instances.Populate()

foreach ($instance in $instances)
{
  $instance.Name | Write-Host
}

Open in new window

I expect you to see "US Business Objects", if the COM service is running. $instance is a COMAdmin.COMAdminCatalogObject, described here https://msdn.microsoft.com/en-us/library/windows/desktop/ms679228(v=vs.85).aspx, but that doesn't help much ;-).
