Removing dynamic text from a temp file in a script - powershell

Question

Ok, I know this is going to end up being basic but I cant seem to figure it out. I am trying to build a tool that will allow us to get the full AD group name for a user. The current problem we have is that the names of our AD groups are long, so a net user MrSmith /domain ends up truncating the full AD group name. I tried using a gpresult -user MrSmith /r but this doesnt return all of the AD groups for some reason.
So I decided that I would create something new that will also have other applications later on. I want to do this by first: doing a net group /domain to pull all of the AD groups in the DC. Second run a net group $ADGroup /domain for each of the ADGroups in the domain and use that output to search for the specified user ID and create a new output that displays the full name of each AD group that user ID is a part of. I am putting this in a drop down GUI for some of the future features I want to add.
Now I have got a good chunk of the first step done, but obviously I am running into an issue. When I do the net group /domain i get output looking like
The request will be processed at a domain controller for domain MyComapny.com.
Group Accounts for \\Server.MyComapny.com
-------------------------------------------------------------------------------
*AD_Group_1
*AD_Group_2
*AD_Group_3
*AD_Group_4
.....
And I add this to a temp .txt file for use.
The Issue I am having is that its not performing the net group $Choice /domain on the AD group selected from the drop down and I dont know why.
Any advice is welcome, I know I am not the best at this so my format and style may not be standard.
Clear-Variable DropDownList
$RawADGroups = Net Group /domain >> 'C:\script_out\RawADList1.txt'
(get-content -path 'C:\script_out\RawADList1.txt') | ForEach-Object {$_ -replace '\*',''} >> 'C:\script_out\RawADList2.txt'
[string[]]$DropDownList = Get-Content -Path 'C:\script_out\RawADList2.txt'
Remove-Item 'C:\script_out\RawADList1.txt'
Remove-Item 'C:\script_out\RawADList2.txt'
function Return-DropDown {
$Choice = $DropDown.SelectedItem.ToString()
if ($Choice)
{net group $Choice /domain
}
}
[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
$Form = New-Object System.Windows.Forms.Form
$Form.width = 340
$Form.height = 150
$Form.Text = "ADGroup"
$DropDown = new-object System.Windows.Forms.ComboBox
$DropDown.Location = new-object System.Drawing.Size(10,10)
$DropDown.Size = new-object System.Drawing.Size(300,30)
ForEach ($Line in $DropDownList) {
$DropDown.Items.Add($Line)
}
$Form.Controls.Add($DropDown)
$DropDownLabel = new-object System.Windows.Forms.Label
$DropDownLabel.Location = new-object System.Drawing.Size(10,10)
$DropDownLabel.size = new-object System.Drawing.Size(200,20)
$Form.Controls.Add($DropDownLabel)
$Button = new-object System.Windows.Forms.Button
$Button.Location = new-object System.Drawing.Size(100,50)
$Button.Size = new-object System.Drawing.Size(100,20)
$Button.Text = "Pick One"
$Button.Add_Click({Return-DropDown})
$form.Controls.Add($Button)
$Form.Add_Shown({$Form.Activate()})
$Form.ShowDialog()
When I click the Pick One button nothing happens, it doesnt reflect anything.

I Figured this out, it was as I thought VERY simple, I was just forgetting to have the command do anything with the output. Hope this might help someone else.
