Close one form, Show the other! [resolved... blah]

[mendhak]

I know this has to be the world's easiest VB.NET question!

Here's what I want: Show form1. Press the button on Form1, and form2 should show up. Form1 should then close.

Here's what I did

In a module:

Module Module1
    Public f1 As New Form1
    Public f2 As New Form2
 
    Sub Main()
        f1.ShowDialog()
    End Sub
 
  
End Module

In form1's button:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        f1.Close()
        f2.Show()
 
 
 
    End Sub

And that's it!

Now when I click the button, form2 appears briefly and then disappears.

Surely it has to be something simple. What am I missing?
