Build Checkbox list programmatically using powershell - powershell

Question

I am trying to populate checkbox from value return in $domain = Get-MsolDomain which return domains available then generate the checkbox based on the value return and excluding the value from #mail. Thank you
Here is the code that i have so far:
$snapin = Get-PSSnapin | Where-Object {$_.Name -eq 'Microsoft.SharePoint.Powershell'}
if ($snapin -eq $null)
{
Write-Host -foregroundcolor Green "Loading SharePoint PowerShell Snapin"
Add-PSSnapin "Microsoft.SharePoint.Powershell"
}
Import-Module MSOnline
$credentials = Get-Credential
Connect-MsolService -Credential $credentials
$unlicensedUsersBatch500 = Get-MsolUser -UnlicensedUsersOnly -MaxResults 500
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$Form = New-Object System.Windows.Forms.Form
$Form.Size = New-Object System.Drawing.Size(600,700)
$Form.text ="Office 365 Licence Activation"
############################################## Start group boxes
$groupBox = New-Object System.Windows.Forms.GroupBox
$groupBox.Location = New-Object System.Drawing.Size(240,20)
$groupBox.size = New-Object System.Drawing.Size(200,100)
$groupBox.text = "Availabe Office 365 Domains:"
$Form.Controls.Add($groupBox)
$Checkboxes += New-Object System.Windows.Forms.CheckBox
$Checkboxes.Location = New-Object System.Drawing.Size(10,20)
$domain = Get-MsolDomain
foreach ($a in $domain)
{
for ($i=1;$i -lt 6; $i++)
{
$Checkboxes.Text = $a.Name
}
}
$groupBox.Controls.Add($Checkboxes)

I would do it as follows. Note that I created and populated $domain for the sake of testing, so you will need to replace that with your call to Get-MsolDomain.
Small plus, the size of the groupbox will grow automatically, based on the number of elements in $domain.

$Checkboxes = #()
$y = 20
foreach ($a in $domain)
{
$Checkbox = New-Object System.Windows.Forms.CheckBox
$Checkbox.Text = $a.Name
$Checkbox.Location = New-Object System.Drawing.Size(10,$y)
$y += 30
$groupBox.Controls.Add($Checkbox)
$Checkboxes += $Checkbox
}
$groupBox.size = New-Object System.Drawing.Size(200,(40*$checkboxes.Count))
$form.ShowDialog()| Out-Null
