Powershell listbox item different value from item text? - winforms

Question

I have found ways of doing this in C#, HTML, and Xojo, but not Powershell/Windows Forms...
I have created a Listbox for users to select a location code for software we use...while the software installation requires the specific code (01-07), I would like to show the users the actual location in the Listbox UI. Is this possible? Something like $listBox.Items.Add(Value="01" Text="NYC")?
See below for code:
$label = New-Object System.Windows.Forms.Label
$label.Location = New-Object System.Drawing.Point(10,20)
$label.Size = New-Object System.Drawing.Size(280,20)
$label.Text = "Please select a Location Code:"
$form.Controls.Add($label)
$listBox = New-Object System.Windows.Forms.ListBox
$listBox.Location = New-Object System.Drawing.Point(10,40)
$listBox.Size = New-Object System.Drawing.Size(150,20)
$listBox.Height = 140
[void] $listBox.Items.Add("01")
[void] $listBox.Items.Add("02")
[void] $listBox.Items.Add("03")
[void] $listBox.Items.Add("04")
[void] $listBox.Items.Add("06")
[void] $listBox.Items.Add("07")
$form1.Controls.Add($listBox)
$form1.Topmost = $True
$result1 = $form1.ShowDialog()
if ($result1 -eq [System.Windows.Forms.DialogResult]::OK)
{
$Server = $listBox.SelectedItem
$Server
}

Answer 1

Short of looking into the inner workings of how a listbox functions, you could just make a hashtable to convert friendly names to numbers for the software installation.
$locHash = #{
'NYC' = '01'
'Chicago' = '02'
'LA' = '03'
'Seattle' = '04'
'Orlando' = '05'
'Dallas' = '06'
}
Then you can add the friendly names to the listbox, and just reference the hashtable when you go to install the software.
[void] $listBox.Items.Add("NYC")
[void] $listBox.Items.Add("Chicago")
[void] $listBox.Items.Add("LA")
[void] $listBox.Items.Add("Seattle")
[void] $listBox.Items.Add("Orlando")
[void] $listBox.Items.Add("Dallas")
$form1.Controls.Add($listBox)
$form1.Topmost = $True
$result1 = $form1.ShowDialog()
if ($result1 -eq [System.Windows.Forms.DialogResult]::OK)
{
$Server = $locHash[$listBox.SelectedItem]
$Server
}
