Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim frm2 As New Form2
    AddHandler frm2.FormClosed, AddressOf Form2Closing
    frm2.Show()
    Me.Hide()

End Sub

Private Sub Form2Closing(sender As Object, e As FormClosedEventArgs)
    Me.Show()
    RemoveHandler DirectCast(sender, Form2).FormClosed, AddressOf Form2Closing
End Sub

You better not close your form after opening another one from it, unless you want that other one also closed. Otherwise it will cause ownership and visibility side effects, which you really don't want to deal with in the long run.

This is exactly why me.close() on your main form stops your project. You just have consider paradigms Microsoft put into a Winforms application. If you don't, you are guaranteed to get in trouble.

Instead, a wizard control is what you are probably looking for.

If you just want Form2 to be Visible you can hide Form1 when you show Form2, then show it Form1 again when you close Form2. What is happening is that once you close Form1 your program will exit see below edit.

Something like this.

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim frm2 As New Form2
    AddHandler frm2.FormClosed, AddressOf Form2Closing
    frm2.Show()
    Me.Hide()

End Sub

Private Sub Form2Closing(sender As Object, e As FormClosedEventArgs)
    Me.Show()
    RemoveHandler DirectCast(sender, Form2).FormClosed, AddressOf Form2Closing
End Sub

If you just are wanting to Close Form1 and not go back to it once Form2 is open, you can change your project settings from When startup form closes(which is the default) to When last form closes then you can close your first form without closing your application.

You have to specify what to close: 

  Form1.Close()
