Standard and Advanced PowerShell functions

This post is part of the PowerShell Blogging Week (#PSBlogWeek), a series of coordinated posts designed to provide a comprehensive view of a particular topic.

This week topic will be focused on Windows PowerShell Advanced Functions.


In this post, we'll discuss Standard and Advanced Functions and why you should write advanced functions.


When you have been working with PowerShell for some time, creating reusable tools is an obvious evolution to avoid writing the same code over and over again. You will want to have modular pieces of code that only do one job and do it well - that’s the role of functions.

Let's suppose you have to accomplish a task that requires multiple lines of code, for example:

# Computer System
Get-WmiObject -Class Win32_ComputerSystem
# Operating System
Get-WmiObject -class win32_OperatingSystem
# BIOS
Get-WmiObject -class Win32_BIOS

Update: LazyTS v1.1

I found some time over the week-end to fix some bugs and add a few things to LazyTS. You'll now be able to quickly search though the displayed data using the small highlight util and open a Remote Desktop connection using the Shadow feature (View and Control)

See this link for more information about RDP Shadow.

What is LazyTS ?

LazyTS is a PowerShell script to manage Sessions and Processes on local or remote machines. It also allows you to Disconnect/Stop sessions and Send Interactive message to one or more sessions.

This tool is using the module PSTerminalService which relies on the Cassia .NET Library.I used Sapien PowerShell Studio 2014 to which make life easier if you want to start building WinForms tools and add PowerShell code.


Feature requests and Bugs report
I also want to thank those who are sending me features request and reporting bugs ! This is greatly helpful !!! Merci!! You can contact me using info (at) lazywinadmin.com

2015/03/04 Update: Fixed issue when using RDP Shadow and getting the error "This computer name is invalid"
2015/03/02 Update: Fixed a small issue where you got the following message : Exception setting "Item": "Exception calling "Set_Item" with "2" argument(s): "Cannot set Column 'CurrentTime' to be null. Please use DBNull instead."" This was related to an issue with ConvertTo-DataTable
