Hello guys!
Sorry for noob question.
How can I get all available values of the object property? My english is bad, so i append my question with an example
we have cmdlet get-service. Object cmdlets returns has a property Status.
PS C:\Users\lopyeg> (get-service)[2] |get-member

TypeName: System.ServiceProcess.ServiceController

Name MemberType Definition
---- ---------- ----------
Name AliasProperty Name = ServiceName
...
Status Property System.ServiceProcess.ServiceControllerStatus Status {get;}

Question: How can I see all available values of Status (running| stopped| paused maybe)?

is it important for discovering powershell and selecting...

thank you for response

Get-Service[2] | Format-List *

it returns only
Status : Stopped
but not all vailable values of Status

Get-Service | Group status

So sorry, I misunderstood your question and thought you wanted all properties from a single service.

no i want to get all possible values from some property

i want to know does Status be equal "paused", for example

(Get-Service)[2].status |get-smthmagic
StatusCanBe Value
————— ———
stopped
running
hanging
paused

You can only retrieve the status values that are actually in use on a system (Use Klaas's method to achieve this). In order to find all the possible status values, whether they actually exist on a server or not, you'll need to find it in MSDN. It looks to me like the values are in the ServiceControllerStatus enumeration. You can find it at
http://msdn.microsoft.com/en-US/library/system.serviceprocess.servicecontrollerstatus(v=vs.80).aspx
The values are]
ContinuePending
Paused
PausePending
Running
StartPending
Stopped
StopPending
[/list]

Thank you for response

the Service status was an example)
is it some cmdlet to get values of any property?
for AD objects for example?

Hi,
to be able to retrieve all of the available values they must be taken from a final set, in case of .net it is usually enum. To learn if the property you are interested in is enum look at its base type.
$statusValue = Get-service | select -First 1 | select -ExpandProperty status
$statusValue.getType()

IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True ServiceControllerStatus System.Enum

If the base type is enum you can use static methods of the enum class to list the available values of the type:
[Enum]]
Stopped
StartPending
StopPending
Running
ContinuePending
PausePending
Paused

it seems, i am to young in PoSh)))
i could not write a function...

if your run 'get-service|gm'
Status Property System.ServiceProcess.ServiceControllerStatus Status {get;}

And if you look up the System.ServiceProcess.ServiceControllerStatus Status .NET in Powershell:
[enum]::GetValues("System.ServiceProcess.ServiceControllerStatus")
You'll get the values mentioned above

(Credit for this goes to Claus Nielsen)

Give it some time, I am sure you'll figure it out once you get bit more into PowerShell. 🙂

There are lots of ways by which we can increase our property values. Koh samui has already high rated properties.
