Add Array Items to Listbox

Hello. I'm relatively new to PowerShell and have only been working with it for a few weeks. I am trying to add the items in an array to a listbox. I am working with Active Directory. I would like to allow the user to select an account after searching by last name in Active Directory. Once they enter the name, I would like to populate a listbox with all the names found in the search results. The code that I have currently returns the names, but it does not put them into the listbox.

Here is the code that I have so far:

Import-Module ActiveDirectory

$nameForm = New-Object System.Windows.Forms.Form 
$nameForm.Text = "Name Entry"
$nameForm.Size = New-Object System.Drawing.Size(300,200) 
$nameForm.StartPosition = "CenterScreen"

$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(75,120)
$OKButton.Size = New-Object System.Drawing.Size(75,23)
$OKButton.Text = "OK"
$OKButton.Add_Click({$nameForm.Close()})
$nameForm.Controls.Add($OKButton)

$CancelButton = New-Object System.Windows.Forms.Button
$CancelButton.Location = New-Object System.Drawing.Size(150,120)
$CancelButton.Size = New-Object System.Drawing.Size(75,23)
$CancelButton.Text = "Cancel"
$CancelButton.Add_Click({$nameForm.Close()})
$nameForm.Controls.Add($CancelButton)

$nameLabel = New-Object System.Windows.Forms.Label
$nameLabel.Location = New-Object System.Drawing.Size(10,20) 
$nameLabel.Size = New-Object System.Drawing.Size(280,20) 
$nameLabel.Text = "Please enter the last name in the space below:"
$nameForm.Controls.Add($nameLabel) 

$nameTextBox = New-Object System.Windows.Forms.TextBox 
$nameTextBox.Location = New-Object System.Drawing.Size(10,40) 
$nameTextBox.Size = New-Object System.Drawing.Size(260,20) 
$nameForm.Controls.Add($nameTextBox) 

$nameForm.Add_Shown({$nameForm.Activate()})
[void] $nameForm.ShowDialog()

$name = $objTextBox.Text

$strFilter = "(&(objectCategory=User)(sn=$name))" 
$objDomain = New-Object System.DirectoryServices.DirectoryEntry 
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher 
$objSearcher.SearchRoot = $objDomain 
$objSearcher.PageSize = 1000 
$objSearcher.Filter = $strFilter
$colProplist = "name" 
foreach ($i in $colPropList){$objSearcher.PropertiesToLoad.Add($i)} 
$colResults = $objSearcher.FindAll() 

foreach ($objResult in $colResults) 
{
    $names = $objResult.Properties; $names.name
}

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")  

$nameListBox = New-Object System.Windows.Forms.ListBox 
$nameListBox.Location = New-Object System.Drawing.Size(10,40) 
$nameListBox.Size = New-Object System.Drawing.Size(260,20) 
$nameListBox.Height = 80

[void] $nameListBox.Items.Add("$names")

$lbForm = New-Object System.Windows.Forms.Form 
$lbForm.Text = "Name Entry"
$lbForm.Size = New-Object System.Drawing.Size(300,200) 
$lbForm.StartPosition = "CenterScreen"

$lbForm.Controls.Add($nameListBox) 

$lbForm.Topmost = $True

$lbForm.Add_Shown({$lbForm.Activate()})
[void] $lbForm.ShowDialog()
