Check an Array Field is Empty when Type = Form

[Formby]

I have an array set up to receive the names of forms when they open. The form name is sent as a Form not a String therefore when I run my code I cannot check for whether the field is empty in the normal way (ie. array(1) = "") as the "" are only usable with strings!

Dim Forms(24) As Form
Dim i As Integer
Dim Free As Integer = -1

Do
  If Forms(i) =  Then
    Free = CInt(i)
  End If
Loop Until Free <> -1

I only need a solution to do the same as array(1)="" but for windows forms.

Thanks for the help!
