Working with a login script for my lab active directory.
100% PowerShell using .NET classes and WMI.

This is VBScript login scripts with HTA on steroids

The GUI part was done in 10-15 min with Primal Forms.

I made this function back in 2007.
But I did only published It in Swedish then. This function helps me a lot when I’m working
with PowerShell and Dot Net classes.

When I have the Dot Net Class that I want
to use but not much information. Then I just
call this function with the Dot Net Class
and IE opens with the information.

This will be my first post in a long series of
posts, screencasts and other things related to
PowerShell and .net forms with one of my favorite
tools, Primal Forms (Community Version).

I love this tool because of that It’s so easy to take
a old PowerShell script or a function and make a forms
for It in 5 minutes.

Windows forms tools will draw a bigger audiences to It
then ordinary PowerShell scripts will.

In this first example I will only do a simple form with
a close button and a label that will show the Internet
IP Address.

And then we export the form to PowerShell and get this code:

If we run this code we will get this dumb form.

No information and the close button will not work.

To incorporate my Get-MyInternetIP function

we just add the code for the Get-MyInternetIP code

above the form code.

Function Get-MyInternetIP {

if ($WebClient -eq $null) {$Global:WebClient=new-object System.Net.WebClient  }

$url="http://ip-address.domaintools.com/myip.xml"

$myInternetIP=([xml]($WebClient.DownloadString($url))).dnstools.ip_address

$myInternetIP

}

And then add

$form1.close()

to the

$btnClose_OnClick=

section

And at the en add

$lblIPAddress.Text = Get-MyInternetIP

Thats It!

All the code:

Function Get-MyInternetIP {
if ($WebClient -eq $null) {$Global:WebClient=new-object System.Net.WebClient  }
$url="http://ip-address.domaintools.com/myip.xml"
$myInternetIP=([xml]($WebClient.DownloadString($url))).dnstools.ip_address
$myInternetIP
}
