Call Windows Runtime Classes from PowerShell - powershell

Is there a way to call Windows Runtime (WinRT) classes (or objects) from a PowerShell script? I know that you can call COM objects, which WinRT classes are supposed to be "exposed" as ... but so far my attempts have failed...
This is my code I'm trying:
$lockscreen = New-Object -comObject Windows.System.UserProfile.LockScreen
Which gives me the following error:
New-Object : Retrieving the COM class factory for component with CLSID {00000000-0000-0000-0000-000000000000} failed
due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
Does anyone know the correct "COM Class" that I should be using for WinRT classes?

just reference the type, to "load" the assembly...
[Windows.System.UserProfile.LockScreen,Windows.System.UserProfile,ContentType=WindowsRuntime]
[Windows.System.UserProfile.LockScreen]::OriginalImageFile
if you don't want the type to be returned in your powershell results then
$null = [Windows.System.UserProfile.LockScreen,Windows.System.UserProfile,ContentType=WindowsRuntime]

Here is something hacky that seems to work:
PS> new-object "Windows.System.UserProfile.LockScreen,Windows.System.UserProfile,ContentType=WindowsRuntime"
new-object : Constructor not found. Cannot find an appropriate constructor for type
Windows.System.UserProfile.LockScreen,Windows.System.UserProfile,ContentType=WindowsRuntime.

Note that the first call fails because LockScreen has no constructor but that call does something to pull in the WinRT projection/metadata such that you can now call the static methods/properties on the LockScreen class.
DISCLAIMER: there isn't any documentation that I can find on this New-Object syntax so it is entirely possible that Microsoft could change it considering it is essentially a "hidden" and probably not fully developed feature.

Unable to modify value of a nested property in PS custom object

I have a PS custom object:
TourCode : s
TournamentNumber : 524
TournamentName : Mitsubishi Electric Championship at Hualalai
EnvironmentType : PGA Tour
TournamentRootPath : /mitsubishi-electric-championship-at-hualalai
SValues : {#{S1=championstour; S2=tournaments; S3=mitsubishi-electric-championship-at; S4=}}
I can easily modify values of the top level properties like TourCode or TournamentName:
PS C:\Users\yuriy> $testTournament.TourCode = 'r'
PS C:\Users\yuriy> $testTournament
TourCode : r
TournamentNumber : 524
TournamentName : Mitsubishi Electric Championship at Hualalai
EnvironmentType : PGA Tour
TournamentRootPath : /mitsubishi-electric-championship-at-hualalai
SValues : {#{S1=championstour; S2=tournaments; S3=mitsubishi-electric-championship-at; S4=}}
But I'm stuck getting strange error message when trying to modify properties S1, S2, S4, or S4 within SValues property:
PS C:\Users\yuriy> $testTournament.SValues.S3 = 'newvalue'
The property 'S3' cannot be found on this object. Verify that the property exists and can be set.
At line:1 char:1
+ $testTournament.SValues.S3 = 'newvalue'
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : PropertyAssignmentException
Why is it saying it cannot find the property? I can get its value easily by referring to it like this:
PS C:\Users\yuriy> $testTournament.SValues.S3
mitsubishi-electric-championship-at
What am I doing wrong?
UPD: Output of gm -i $testTournament.SValues is on screenshot: http://i.imgur.com/BeRr2aJ.png
JSON fragment is on screenshot: http://i.imgur.com/BBK2nsi.png (similar data)
The JSON file is read and converted using this code:
$testData = Get-Content -Raw -Path "Test Data.json" | ConvertFrom-Json
Then $testTournament is created:
$testTournament = $testData.Tournaments | Get-Random

Override Creation for Monitors and Rules

I want to create PowerShell scripts to override some parameter of my monitor and rule. I used the below code, but I have some errors. I want override my overidable parameter not enabled or something else. How can I doe this?
$mps = Get-SCOMManagementPack | ? {$_.Name -like "test"}
$overrideMp = Get-SCOMManagementPack -DisplayName "Overrides"
$overridename = "testmonitor.Overrides"
$monitor = 'testmonitor'
$override = New-Object Microsoft.EnterpriseManagement.Configuration.ManagementPackMonitorPropertyOverride($overrideMp,$overridename)
$override.Monitor = $monitor
$override.Property = 'WarningThreshold'
$override.Value = 80
$override.DisplayName = "Overrides"
$overrideMp.Verify()
$overrideMp.AcceptChanges()
Errors:
error1: Exception setting "Property": "Cannot convert value "WarningThreshold" to
type "Microsoft.EnterpriseManagement.Configuration.ManagementPackMonitorProperty".

The error message looks rather clear to me. There is no property WarningThreshold in the ManagementPackMonitorProperty enumeration. I don't have much experience with SCOM, but you probably need to override the property AlertOnState for monitors where the property AlertSeverity has the value Warning.
Try something along the lines of this:
$mps | Get-SCOMMonitor | Where-Object {
# (other selection criteria) -and
$_.AlertSettings.AlertSeverity -eq 'Warning'
} | ForEach-Object {
$ctx = Get-SCOMClass -Id $_.Target.Id
# ...
$override = New-Object ...
$override.Monitor = $_
$override.Property = 'AlertOnState'
$override.Value = 80
$override.Context = $ctx
# ...
}
Code adopted from here (probably the same place where you found it). Not sure if this works, though. Like I said, I have very little experience with SCOM, and I don't have a SCOM server available for testing.
I'll try to debug it tomorrow in the office.
BTW, there is a third-party tool for override management called MPTuner: http://mpwiki.viacode.com/default.aspx?g=mptuner
It's free so you should try.
Roman.
It's quite confusing, but there are two different type of overrides for each workflow type. For a monitor there are:
MonitorPropertyOverride
MonitorConfigurationOverride
You are using the first one, wgich is for standard parameters only, like Enabled, for example. For any custom parameters use Configuration Override.

PowerShell and VB6 COM+ modules: Object variable or With block variable not set

I´m trying to use powershell to do automatic tests in my system, but 30% of this system is VB6 modules used thru COM. Some os these modules uses private variables that are globals inside the module. With VB6 functions that don´t use these variables, everything works fine, but with the functions that rely on these "private globals", I´m getting the error "Object variable or With block variable not set". Unfortunately, migrate this VB6 code will not occur in short term.
This is a piece of this legacy code:
VERSION 1.0 CLASS

Persistable = 0 'NotPersistable
DataBindingBehavior = 0 'vbNone
DataSourceBehavior = 0 'vbNone
MTSTransactionMode = 1 'NoTransaction

Dim sSql As String
sSql = "select * from operator"
Call Connect(sUser, sPassword, sSystem, sModule, sIP)
oRs.CursorType = adOpenStatic
oRs.CursorLocation = adUseClient
oRs.Open sSql, oConn, , adLockBatchOptimistic
oRs.ActiveConnection = Nothing
Set rsOperadora = oRs
Set oConn = Nothing
End Function

In this example, the function Connect open a database connection using ADO, assigning to the variable oConn.
I think my problem is the variable oRs.
Inside ASP Classic this module works.

PowerShell InvokeGet the directory property cannot be found

We needed to retrieve the information in active directory concerning 'Terminal Services'. For this I've created a function that works fine most of the time. However, with some users we have issues.
The code:
Function Get-ADTSProfile {
[CmdletBinding()]
Param(
[Parameter(Mandatory=$true,Position=0)]
[String] $DistinguishedName,
[parameter(Mandatory=$true,Position=1)]
[ValidateNotNullOrEmpty()]
[ValidateSet('UserProfile','AllowLogon','HomeDirectory','HomeDrive')]
[String]$Property
)
Begin {
$User = [ADSI]"LDAP://$DistinguishedName"
}
Process {
Switch ($Property) {
'AllowLogon' {if ($($User.psbase.InvokeGet('allowLogon')) -eq '1'){$True}else{$False}}
'HomeDirectory' {$User.psbase.InvokeGet('TerminalServicesHomeDirectory')}
'HomeDrive' {$User.psbase.InvokeGet('TerminalServicesHomeDrive')}
'UserProfile' {$User.psbase.InvokeGet('TerminalServicesProfilePath')}
}
}
}
The error:
Get-ADTSProfile -DistinguishedName 'CN=test\, test (Den Bosch) NLD,OU=Users,OU=Disabled,OU=NLD,OU=EU,DC=domain,DC=net' -Property 'UserProfile'
Exception calling "InvokeGet" with "1" argument(s): "The directory property cannot be fo

I can't really figure out why it works on some and not on all..
I've been working on a recent project that uses ADSI to set and read Terminal Services attributes. From my testing anytime you perform a "InvokeGet({TS Attribute})" a COM exception will be thrown with the message "The directory property cannot be found in cache"
This seems to occur only when the "userParameters" attribute is not set in AD. Maybe the attribute internally checks the ADSI cache for userParameters? So i'm thinking logically you could check the DirectoryEntry for userParameters first, then try and read the properties, or else set it to construct the blob
if ($user.Properties.Contains("userParameters"))
{
#Read the Property from ADSI
Write-Host $user.InvokeGet("TerminalServicesProfilePath")
} else {
#Set the property to construct the userParameter blob
$user.InvokeSet("TerminalServicesProfilePath", "\\somepath")
$user.CommitChanges()
}
Even if the userParameters attribute is not set, you can still perform an InvokeSet to have it constructed

Multiple parameter in powershell

I have a powershell script to call the SP which is shown below
$sqlTableConnection = New-Object [System.Data.SqlClient.SqlConnection]("Server=1xx.xx.xxx; Database=dbName; Integrated Security= True");
$sqlTableCmd = New-Object [System.Data.SqlClient.SqlCommand]
$sqlTableCmd.CommandText = "[System_Control].[usp_Check_system]"
$sqlTableCmd.Connection = $sqlTableConnection;
$jobName1 = "MASTER_JOB";
$sqlTableCmd.Parameters.AddWithValue("#JobName", $jobName1) ;
$outParameter = new-object System.Data.SqlClient.SqlParameter;
$outParameter.ParameterName = "#JobSatatus";
$outParameter.Direction = [System.Data.ParameterDirection]'Output';
$outParameter.DbType = [System.Data.DbType]'Boolean';
$sqlTableCmd.Parameters.Add($outParameter) ;
$sqlTableCmd.Connection = $sqlTableConnection
$sqlTableConnection.Open();
$sqlTableCmd.ExecuteNonQuery();
$truth = $sqlTableCmd.Parameters["#JobSatatus"].Value;
$sqlTableConnection.Close();
$truth;
but when I am running this I am getting below error
Exception calling "ExecuteNonQuery" with "0" argument(s): "The variable name '#
JobName' has already been declared. Variable names must be unique within a quer
y batch or stored procedure."
At line:15 char:33
+ $sqlTableCmd.ExecuteNonQuery <<<< ();
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException
Where I am doing mistake?
You should only be getting that error if you aren't re-initializing the SqlCommand object and so it has #JobName already defined.
I suspect you are getting this when you run it manually, not when you execute the script as a whole..
OR, if you are seeing it all the time, then maybe you moved this code into a function but the original $sqlTableCmd was initialized in the main code and now when this executes, it is in a different scope, but is getting confused by the one that was defined in the higher scope?
As I understand it, this line here is the one that should be setting things up fresh for you:
$sqlTableCmd = New-Object [System.Data.SqlClient.SqlCommand]
