[2008] Open and Close(all but first) with modal or zorder forms

[jamezbob]

I'm trying to get multiple forms to open/close in a certain way. I want them to either be modal, stay on top with zorder, or something similar...so, the user will have to: a) give input, b) can ask for help in that form with another button, or LogOut. It needs to be able to close all other forms back to the first (form1) with a LogOut button at other point. So, right off I was playing with modal and couldn't get Form2 to close. I'm not sure if this is the better way to approach it though or the details of how. If anyone has any better ways, I'd be glad to hear, thanks. (VS 2008)

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim form2Active As New Form2
        form2Active.ShowDialog()
    End Sub
End Class

Public Class Form2
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim form3Active As New Form3
        form3Active.ShowDialog()
    End Sub
End Class

Public Class Form3
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Form2.Close()
        Me.Close()
    End Sub
End Class
