What's wrong with this code?

[vvenk]

Hello:

I have two forms, Form1 and Form2. Form1 has a command button that will open
Form2. There can only be one Form2 open at any time.

Here's my code:

Public Class Form1
Inherits System.Windows. Forms.Form
Private formForm2 As New Form2
+ Windows Form Designer generated code "

Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click

If formForm2 Is Nothing Then
formForm2 = New Form2
End If
formForm2.Show( )
formForm2.Activ ate()
End Sub
End Class
This works fine except when I close Form2 and click on the command button. I
get an exception:

An unhandled exception of type 'System.ObjectD isposedExceptio n' occurred in
system.windows. forms.dll

Additional information: Cannot access a disposed object named "Form2".

How do I solve this issue?

Thanks for your help.

If formForm2 Is Nothing OrElse formForm2.IsDis posed Then
formForm2 = New Form2
End If
formForm2.Show( )
formForm2.Activ ate()

Of course, there is more than one way to skin the cat. But your solution is
by far the most elegant.

Thanks a lot.
