Close previous form

I need a quick fix piece of code that closes a window/form in a vb.net app.  when  the user clicks on the "save" button, the code passes parameters to the new form.  I  want the previous form to close at that point.

Thanks in advance.

We need  more info TimSweet220...

What version VB.Net?     2005?     2003 (or below)?

What is the "owner" of the previous form?  If the previous form was the "startup" form then closing it usually causes the app to close as well.

Are these standalone forms or Mdi Children?.

etc...

2003.  Separate forms.

And is the "startup form" one of the forms that needs to be closed?

You can simply hide the current form and show the next one using ShowDialog().

If you want to actually close (dispose) of the current form then you have to go thru alot of shenanigans...

Do you need to go in both directions?...or only "forward"?

no it's not a start up form.   I have a form  (form A) that the user fills out.  He clicks the "save" button and the data is saved then in the save function it makes a call the a second form.(Form B)  Form A stays open (behind Form B), I want to add something to the save function in Form that closes that form after it makes the call to Form B. Basically, I don't want the user to be able to go back to Form A with out opening it again from the menu.

I think you've overcomplicated it...

In your main form, show FormA with ShowDialog().
When FormA closes, show FormB with ShowDialog().
You won't be able to interact with the main form until both forms are closed.

Something like...

Public Class YourMainForm

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim fa As New FormA
        fa.ShowDialog()
        Dim fb As New FormB
        fb.ShowDialog()
    End Sub

End Class

If you need to, you can create FormB and show it via ShowDialog() from the Closing() event of FormA:

Public Class FormA

    Private Sub FormA_Closing(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
        Me.Hide()
        Dim fb As New FormB
        fb.ShowDialog()
   End Sub

End Class

Form.ShowDialog() prevents interaction with anything else until that form is closed:

        '-------Code to save data
        Dim FrmFormB As New FormB
        '-------If you want to pass any value to FormB
        '-------Store them on a public variable which is in FormB.
        '-------ex: FrmFormB.PassValue = 10
        FrmFormB.Show()
        Me.Close()

    End Sub
End Class
