Is it possible only create form once and active the form second time?

[foxchan]

A Newbie question. Is it possible?

Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
Dim oNewForm As Form1
'if already create a form for form.text="Just One" then
JustOne.show()
'else
oNewForm = New Form()
oNewForm.Text = "JustOne"
oNewForm.Show()
end if
End Sub
