Show Form2 7seconds delayed after Form1 close - vb.net

Question

I have two forms in my application, form2 is shown on clicking a button in the form1. but i need a delay of 7 seconds between form1's close and form2's show for that i wrote the following code:
Public Class Form1
Dim i As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
i = 0
Me.Close()
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
i += 1
If i = 7 Then
Form1.Show()
End If
End Sub
End Class
But it does not give me the result. form2 not shown at all. what was the mistake i had made in the code? can anyone help me?
Thanks in advance.

Answer 1

When there's no active form left in a Windows Forms application, the application will quit. Therefore, you might want to hide the main form instead of closing it:
Me.Hide()

Answer 2

i think no need of unnecessary declaration for time delay because you can simply set it on your timer control itself
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Interval = 7000
Timer1.Start()
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Form2.Show()
Me.Close()
End Sub
End Class
or
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Interval = 7000
Timer1.Start()
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Me.Close()
End Sub
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Form2.Show()
End Sub
