CT-Standard

1.13.20

CT-Standard.psm1

<#
--------------------------------------------------------------------------------------------------
 
This is a standard module with a set of standard functions used across multiple scripts within CT.
 
Any changes to this module need to be published using the powershell script "Build_CT_Module.ps1"
 
--------------------------------------------------------------------------------------------------
HOW TO IMPORT INTO SCRIPT:
--------------------------------------------------------------------------------------------------
This module should be imported using the commands below (do not copy the asterix's, just whats between).
This will import this module if the latest version isn't already on the device AND initialise the
script with all the standard features required by scripts, including all the log files for each transaction
Add any other modules that need to be imported to the array of ModuleNames AFTER this module
*****************
 
$ModuleNames = @("CT-Standard")
foreach($ModuleName in $ModuleNames) {
    if((Get-InstalledModule -Name $ModuleName -ErrorAction SilentlyContinue) -eq $null) { Install-Module -Name $ModuleName -Force -AllowClobber -Repository PSGallery -Verbose:$VerbosePreference -ErrorAction Stop } else { if((Get-InstalledModule -Name $ModuleName).version -ne (Find-Module -Name $ModuleName).version) { Update-Module -Name $ModuleName -Force -ErrorAction Stop }}
    Import-Module -Name $ModuleName -Force -Verbose:$VerbosePreference -ErrorAction Stop
}
 
*****************
If this does not work or fails (often because of issues with PowerShell default settings or PSGallery or NuGet are corrupted), use the code below.
*****************
 
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Register-PSRepository -Default -Verbose:$VerbosePreference -ErrorAction SilentlyContinue
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.208 -Force -ErrorAction Continue -Verbose:$VerbosePreference
Install-Module -Name "CT-PS-Standard" -Force -AllowClobber -Verbose:$VerbosePreference -ErrorAction Stop

LOG FILES
--------------------------------------------------------------------------------------------------
There are four log files initialised by this module that can be used for output.
You can write to each of these logs accordingly.
 
$Output_Log: This is the standard console output.
$Transcript_log: This is where the transcript is written to. You will need to start and stop the transcript inside your script by using the command "Start-Transcript -Path $Transcript_log -append | Out-Null"
$API_log: This is where the output from API posts should be sent.
$Install_log: This is where output from MSIEXEC commands should be logged

Function Set-WMIValue {
<#
This function is used to set a WMI property using CIM. If the namespace or class do not exist, it will be created.
 
All parameters can be pipelined by their respective propertyname
 
PARAMETERS:
-Namespace: Specifies the namespace where to search for the WMI class. Default is: 'ROOT\cimv2'.
-ClassName: Specifies the class where to create the new WMI instance.
-KeyID: (Optional) Specifies the property within the $Property hashtable that is used as the key. If an instance with the key exists, it will be updated. If it does not, it will be created as a new instance.
            If omitted, the current datetime and calling script will be used as the key value for creating a new instance using the key property "CT_Key"
-Property: Specifies the class instance Properties or Values.
            Example of hashtable:
            [hashtable]$Property = @{
                'ServerPort' = '89'
                'ServerIP' = '11.11.11.11'
                'Source' = 'File1'
