closing MDI Application with a button

[painkiller]

hi,

im developing a mdi application and want to close this application and all its child forms using a button but im not sure how to do it. Please note that this button is NOT in parent form but in one of the child form. here is my sample code. is it correct way to do it??

Private Sub btnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click
        Dim frm As New frmMain 'this is the parent form
        For Each temp As Form In frm.MdiChildren
            temp.Dispose()
        Next
        Application.Exit()
End Sub 

im using .NET 1.1 and VS 2003

Can you get away with doing:

Me.Parent.Close
 

???

yes i can but i dont think it will close all other child forms. what u say???

If you close the parent form (which is MDI type), the child forms attached to it will close too.
If you want to exit the application
Application.Exit does the trick, however you will need to find the equivalent of it in vb .net

Application.Exit actually works in vb.net

so i guess its just Application.Exit and all other child forms will be closed automatically (both hidden and not-hidden) ???

Yes, Application.Exit will shut down the entire application thread. (and its children)

hi
you use following code
Form[] charr= this.MdiChildren;

//For each child form set the window state to Maximized
foreach (Form chform in charr)
chform.Dispose();
