Program Wont Close

I have a program starting with FormA, and opens to Forms B, C, D, E, etc... When I close forms B, C, D, E, it doesn't close the program. So I added this tidbit of code:

Code:

---

Private Sub AnalysisMain_Closing(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.FormClosing
        Me.Close()
    End Sub

---

This just causes the program to freeze. :(

Im sure theres a simple solution here :)

Well something's obviously causing the program not to close. What you should do is first take the Me.Close out of your FormClosing. Next, set up a breakpoint at your form closing just to make sure your form is indeed trying to close. Some info that may be useful: A)How are you closing the program?(Clicking the red x or in code?) B)What do you expect to happen when you close a form?(Just close that single form or the whole application?) C)Is there perhaps some long running process going on that we don't know about?

you have 5 forms. when exactly should the app. exit?
when all forms are closed, or something different?

A) Pressing red X
B) Close the whole application
C) Not on this application, I have one on another form, but it isnt running in this case. Ill tackle that problem when I get there :)

Code:

---

Private Sub AnalysisMain_Closing(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.FormClosing
    Application.Exit
End Sub

The very first thing I see is that you're calling the form's Close method in the FormClosing event, the funny thing about this is that the only way the FormClosing event fires is if the Close method is called, when your form is already closing there's no need to call its close method.

That being said, I *think* I understand what you're wanting to do, so correct me if I'm wrong.
I think you have two forms open: the "base" form (the one that when closed will end the program) and a secondary form, of which you want to end the program if this form is closed, correct?

If the above is correct, then this should work nicely for you:

vb Code:

Public Class Form1
 
    Private WithEvents frm2 As New Form2
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        frm2.Show(Me)
    End Sub
 
    Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
        If frm2 IsNot Nothing Then
            frm2.Dispose()
        End If
    End Sub
 
    Private Sub Frm2_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles frm2.FormClosed
        Me.Close()
    End Sub
 
End Class

You should avoid calling 'End' and 'Application.Exit' in applications as that causes a hard-stop of your app. None of the Closing and cleanup events are fired and it doesn't allow your apps forms to clean up the objects on them (fonts, labels, textboxes, things in the form's dispose event).
