VB.Net IsDisposed

I found the simple solution for my VB6 habits.
Open and closing a Form multiple time didn't require any special in VB6,
in VB.Net when you close the Form2 it will be disposed, so check if it IsDisposed
to recreate it. See some coding below


Public Class Form1
Dim frm2 As New Form2

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If frm2.IsDisposed Then
' Create it again
frm2 = New Form2
End If
frm2.Show()
End Sub
End Class
