Change the Shutdown Mode in your project properties.

Are you using Visual Studio 2.0? If not, then just add Form1.close() to your close button on form2.

i am using VS 2003. and about form1.close() i have already used this one, its not working telling that refernce to non shares members need object refernce... i am ussing me.close, but if i apply it on form2 then this works for form2 2 only , form1 still remains hidden..

It works fine for me. Could you post your full code for the Form2 close button?

there is no such great code involved in close button... i have jst used like... button2_click() me.close() end sub thats it... and if i also write form1.close then its shows the error i told u in previous post.... you do one thing just tell me your way, i'll implement that method... i just want to close all forms whenevr close button is clicked.. whether its on form2 or any other form say next form form3 or form4.

Alright, just to make sure, goto your project properties (Project Name Properties). Click Application, from there, you should have an option that says Shutdown Mode (or something similar). If there's no such option, then try the following: Dim x As Integer For x = 0 To (Me.OwnedForms.Length) - 1 Me.OwnedForms(x).Close() Next x

Give this a try. What I've done is added a handler for the child forms formclosed event. This way we know when the child is closed and can close too.

Public Class Form1

Private Sub Button1\_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim a As New Form1
    'Register our method (ChildClosed) with the new forms FormClosed event
    AddHandler a.FormClosed, AddressOf ChildClosed
    a.Show()
End Sub

'When the child closes this method will run which will close the current form
Private Sub ChildClosed(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosedEventArgs)
    Me.Close()
End Sub

End Class

***EDIT*** Also what are you doing to go back? **EDIT2*** Oh, ya. You can also just use 'End' or 'Application.exit' to shutdown everything. I forgot about the easy answer :)

The right way to do this, is to have the two forms defined as user controls and showing them both on the one form, your button changes which is visible.

yeah this End and application.exit are working... well to go back i am coding like this.. suppose i am on form 2 and button "back" in back_click dim a as new form1 me.close() ' to close the existing form a.show() here thing is a new form1 gets open by this method... what if i want same form1 which is hidden...?? any idea.?

You could use the same code I posted earlier. However, instead of closing form1 when the child is closed you would just show it. Form2 doesn't need to worry about form1 at all in this case. When the back button is clicked just call me.close. Form1's method will then get called because you registered that method with form2's closed event.
