'duplicating' forms

k, im duplicating a form in runtime but im having trouble trying to reference to it???

VB Code:

Dim f As Form1
Set f = New Form1

using that method, how could i easily reference to each of my duplicate forms? say for instance, add text to a textbox control on one of the forms?

Set the project to start in Sub Main;

Code:

---

Public f As Form1

Sub Main()

 Set f = New Form1
 f.Text1.Text = "Hello"
 f.Show

End Sub

---

You could also use an array eg:
Public f(5) as Form1
