Modify this Powershell custom input box to store multiple variables? - powershell

Question

This textbox was a powershell tip of the week and i really like it.
But I didn't manage to work with it to have 2 variables or even 3 in one input window.
Does anyone know how to do this ? Any help is upvoted immediately.
The Code of the Textbox is here : Input Textbox
The full code is here :
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$objForm = New-Object System.Windows.Forms.Form
$objForm.Text = "Data Entry Form"
$objForm.Size = New-Object System.Drawing.Size(300,200)
$objForm.StartPosition = "CenterScreen"
$objForm.KeyPreview = $True
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Enter")
{$x=$objTextBox.Text;$objForm.Close()}})
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape")
{$objForm.Close()}})
$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"
$OKButton.Add_Click({$x=$objTextBox.Text;$objForm.Close()})
$objForm.Controls.Add($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"
$CancelButton.Add_Click({$objForm.Close()})
$objForm.Controls.Add($CancelButton)
$objLabel = New-Object System.Windows.Forms.Label
$objLabel.Location = New-Object System.Drawing.Size(10,20)
$objLabel.Size = New-Object System.Drawing.Size(280,20)
$objLabel.Text = "Please enter the information in the space below:"
$objForm.Controls.Add($objLabel)
$objTextBox = New-Object System.Windows.Forms.TextBox
$objTextBox.Location = New-Object System.Drawing.Size(10,40)
$objTextBox.Size = New-Object System.Drawing.Size(260,20)
$objForm.Controls.Add($objTextBox)
$objForm.Topmost = $True
$objForm.Add_Shown({$objForm.Activate()})
[void] $objForm.ShowDialog()
$x

You need to repeat adding a few more text boxes:
$OKButton.Add_Click({
$x=$objTextBox.Text
$y=$objTextBox2.Text
$z=$objTextBox3.Text
$objForm.Close()})
...
$objTextBox2 = New-Object System.Windows.Forms.TextBox
$objTextBox2.Location = New-Object System.Drawing.Size(10,65)
$objTextBox2.Size = New-Object System.Drawing.Size(260,20)
$objForm.Controls.Add($objTextBox2)
$objTextBox3 = New-Object System.Windows.Forms.TextBox
$objTextBox3.Location = New-Object System.Drawing.Size(10,90)
$objTextBox3.Size = New-Object System.Drawing.Size(260,20)
$objForm.Controls.Add($objTextBox3)
...
$x,$y,$z
You might need to adjust the Y locations of the OK & Close buttons.
