Don´t Display Notification when Deployment is already installed about toast-notification-script

[imabdk]

Thank you for the suggestion.

I usually suggest using the collections in configmgr for this purpose, but I see how collection refreshes combined with how often hardware inventory is run can results in unwanted toast notifications. Added to my 'might do-list'. Another possibility is that I add the option to only allow the toast notification to run once a day regardless of how the deployment schedule in configmgr may be configured.

It should be easy modification. Just add this code at start of function Display-ToastNotification:

if ($RunApplicationIDValue -and $RunApplicationIDEnabled -eq "True") {
    $TestApplicationID = Get-CimInstance -ClassName CCM_Application -Namespace ROOT\ccm\ClientSDK -ea SilentlyContinue | Where-Object { $_.Id -eq $RunApplicationIDValue }

    if ($TestApplicationID -and $TestApplicationID.InstallState -eq "Installed") {
        Write-Log -Message "Application $RunApplicationID is already installed. Toast notification won't be displayed"
        return
    }
}

So in case, that you define RunApplicationID XML tag, and such application will be already installed, notification won't show.
Of course this code can be placed earlier in the New-ToastNotification script, for sake of better effeciency..

I went a slightly different route and added the following code towards the end of the script, just before it defaults to the fallback toast notification.

# Toast used for Application installation
if ($RunApplicationIDValue -and $RunApplicationIDEnabled -eq "True") {
    $TestApplicationID = Get-CimInstance -ClassName CCM_Application -Namespace ROOT\ccm\ClientSDK -ErrorAction SilentlyContinue | Where-Object { $_.Id -eq $RunApplicationIDValue }

    if ($TestApplicationID -and $TestApplicationID.InstallState -eq "Installed") {
        Write-Log -Message "Application $RunApplicationIDValue is already installed. Toast notification won't be displayed"
    }
    else {
        Write-Log -Message "Application $RunApplicationIDValue is not installed. Displaying toast notification"
        Display-ToastNotification
    }
    # Stopping script. No need to accidently run further toasts
    break
}
