title: Variable Expansion within another Variable (Powershell)
body: <p>So I've an array-variable of servers that is dynamically created from an external script.
  I now need to populate my GUI form with a list of check-boxes for each server.  This will work as a selection mechanism when doing deployments to said servers.</p>
  
  <p>As I don't know how many servers are going to be in my list, this form will have to have the check-boxes created dynamically.  The issue I'm having is setting parameters of these new variables, and adding to the form.  I just don't get how I can force PS to expand my iterator variable within the checkbox variable name.
  Here's what I have currently, which will create my variables but not apply the updates to the parameters:</p>
  
  <pre><code>$form1.Text = "Server Selection"
  $form1.Name = "form1"
  $form1.DataBindings.DefaultDataSourceUpdateMode = 0
  $System_Drawing_Size = New-Object System.Drawing.Size
  $System_Drawing_Size.Width = 235
  $System_Drawing_Size.Height = 500
  $form1.ClientSize = $System_Drawing_Size
  $i = 0
  $y = 0
  $serverList | %{
      New-Variable -Name "Checkbox$i" -value (New-Object System.Windows.Forms.CheckBox)
      set-variable -name "Checkbox$i.VisualStyleBackColor" -value $true
      $System_Drawing_Size = New-Object System.Drawing.Size
      $System_Drawing_Size.Width = 104
      $System_Drawing_Size.Height = 24
      $Checkbox{i}.Size = $System_Drawing_Size
      $Checkbox{i}.TabIndex = $i
      $Checkbox{i}.text = $_
      $System_Drawing_Point = New-Object System.Drawing.Point
      $System_Drawing_Point.X = 60
      $System_Drawing_Point.Y = 21 + $y
      $Checkbox{i}.Location = $System_Drawing_Point
      $Checkbox{i}.DataBindings.DefaultDataSourceUpdateMode = 0
      $Checkbox{i}.name = "server"
      $y = $y + 20
      $i++
      $form1.Controls.Add($Checkbox{i})
  
  
  }
  </code></pre>
  
  <p>Anyone know how I can do this expansion or assignment correctly?</p>
