function Get-CCMClientVersion { <# .SYNOPSIS Returns the current MEMCM client version .DESCRIPTION This function will return the current version for the MEMCM client using CIM. .PARAMETER CimSession Provides CimSessions to gather the version from .PARAMETER ComputerName Provides computer names to gather the version from .PARAMETER PSSession Provides PSSessions to gather the version from .PARAMETER ConnectionPreference Determines if the 'Get-CCMConnection' function should check for a PSSession, or a CIMSession first when a ComputerName is passed to the function. This is ultimately going to result in the function running faster. The typical use case is when you are using the pipeline. In the pipeline scenario, the 'ComputerName' parameter is what is passed along the pipeline. The 'Get-CCMConnection' function is used to find the available connections, falling back from the preference specified in this parameter, to the the alternative (eg. you specify, PSSession, it falls back to CIMSession), and then falling back to ComputerName. Keep in mind that the 'ConnectionPreference' also determines what type of connection / command the ComputerName parameter is passed to. .EXAMPLE C:\PS> Get-CCMClientVersion Returns the MEMCM client version from local computer .EXAMPLE C:\PS> Get-CCMClientVersion -ComputerName 'Workstation1234','Workstation4321' Returns the MEMCM client version from Workstation1234, and Workstation4321 .NOTES FileName: Get-CCMClientVersion.ps1 Author: Cody Mathis Contact: @CodyMathis123 Created: 2020-01-24 Updated: 2020-02-27 #> [CmdletBinding(DefaultParameterSetName = 'ComputerName')] param ( [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'CimSession')] [Microsoft.Management.Infrastructure.CimSession[]]$CimSession, [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'ComputerName')] [Alias('Connection', 'PSComputerName', 'PSConnectionName', 'IPAddress', 'ServerName', 'HostName', 'DNSHostName')] [string[]]$ComputerName = $env:ComputerName, [Parameter(Mandatory = $false, ParameterSetName = 'PSSession')] [Alias('Session')] [System.Management.Automation.Runspaces.PSSession[]]$PSSession, [Parameter(Mandatory = $false, ParameterSetName = 'ComputerName')] [ValidateSet('CimSession', 'PSSession')] [string]$ConnectionPreference ) begin { $getClientVersionSplat = @{ Namespace = 'root\CCM' Query = 'SELECT ClientVersion FROM SMS_Client' } } process { foreach ($Connection in (Get-Variable -Name $PSCmdlet.ParameterSetName -ValueOnly)) { $getConnectionInfoSplat = @{ $PSCmdlet.ParameterSetName = $Connection } switch ($PSBoundParameters.ContainsKey('ConnectionPreference')) { $true { $getConnectionInfoSplat['Prefer'] = $ConnectionPreference } } $ConnectionInfo = Get-CCMConnection @getConnectionInfoSplat $Computer = $ConnectionInfo.ComputerName $connectionSplat = $ConnectionInfo.connectionSplat $Result = [ordered]@{ } $Result['ComputerName'] = $Computer try { [ciminstance[]]$Currentversion = switch ($Computer -eq $env:ComputerName) { $true { Get-CimInstance @getClientVersionSplat @connectionSplat } $false { Get-CCMCimInstance @getClientVersionSplat @connectionSplat } } if ($Currentversion -is [Object] -and $Currentversion.Count -gt 0) { foreach ($SMSClient in $Currentversion) { $Result['ClientVersion'] = $SMSClient.ClientVersion [PSCustomObject]$Result } } else { Write-Warning "No client version found for $Computer" } } catch { $ErrorMessage = $_.Exception.Message Write-Error $ErrorMessage } } } } |
