View 9 RepliesVS 2008 Closing All Forms When Program Closes Vs. Closing All But Main Form
Jun 4, 2010Dim frm As Form
For Each frm In Forms
Set frm = Nothing
Next frm
The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?

Prevent MDI Parent FormClosing From Closing MDI Child Before Check?
Oct 9, 2011I'm trying to give the user a chance to cancel FormClosing of MDI Parent by throwing a "Are you sure?" msgbox with an e.cancel however when FormClosing is invoked by MDI Parent, all MDI Children close first, before the msgbox appears.
I was wondering if there's an easier way to prevent MDI Children from closing rather than having to e.cancel every child form's FormClosing until I get a positive response to close and then push all the close events on the children because that seems like too much of a hassle if you have a lot of MDI Children.
EDIT: I guess the only solution I can find is adding If e.CloseReason = CloseReason.MdiFormClosing Then e.Cancel = True to the FormClosing event and using ApplicationExit instead.
Can't Prevent A Form Shown With ShowDialog From Closing When User Clicks OK Button
Jul 18, 2011I have a VB.NET 2010 Forms Application which includes a form with a textbox, and two buttons which I call from the main form using .ShowDialog

View 1 RepliesHow To Prevent Program Being Started Twice
Apr 8, 2010I have a small problem with my application. When the system starts up, the program starts with it, but runs hidden (registry key with paremeter). The program also has a GUI.I want it so that when the user clicks the desktop icon, it does not start a second instance of the executable, but instead reveals the currently running background process. Is that possible?i.e. when the application is started with the "-startup" paremeter, it loads a hidden form2, and closes form1. When the desktop icon is clicked, it loads form1, while form2 remains hidden.
