forms

[Simon Morris]

If I click Button1, form2 show, then I click Button2 I get.



"An unhandled exception of type 'System.NullRef erenceException ' occurred in
WindowsApplicat ion13.exe


Additional information: Object reference not set to an instance of an
object."





Why does ff = Nothing



Code on Form 1



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

Dim myfrom As New Form2

myfrom.Show()

End Sub



Private Sub Button2_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button2.Click

Dim ff As Form2

Select Case ff.Visible

Case True

ff.Label1.Text = "This is form 2"

End Select

End Sub

Re: forms

You did not instantiate form in Button2_Click. Check how you do declare form
there.
