PowerShell creating Windows Forms

From this Technet blog (link below), it shows how to add a Form and a Label control using PowerShell.
http://blogs.technet.com/b/stephap/archive/2012/04/23/building-forms-with-powershell-part-1-the-form.aspx
The PowerShell script below is a modification from above link.
Here, I will add a Button to the form, and also add an event click listener to the button.
And also add the simple but very useful "Msgbox".
Unlike VB.Net where you can just drag and drop your control on the form and VB.Net will do the necessary things on the background. For PowerShell you have to code the controls and location.
For the script below, location control for x and y coordinates is set.
If the location is not set, the control will be overlapping with each other and other controls cannot be seen.
To dig more about MSDN System Windows Forms, check out link below:

Here's the script below, with comments above the codes:

Outlook VBA Get Contacts on Public Folders

Below is a screen shot of Outlook contact folder:

Above screen shot show the structure of Outlook contact folder, as a developer it's also good to know that the text or the string after the "-" sign is actually the default folder path.
