Forms :: Sub Call To Form Closing Event?
Mar 21, 2011
Going around in circles here. I have an Exit button (Barbuttonitem6) on my form and would like the FormClosing event to handle this. The code works fine for the FormClosing event but when i try to call the Formclosing event from Barbuttonitem6, it does not work (The form does not close if i choose Yes to save or No)
Public Sub BarButtonItem6_ItemClick(ByVal sender As System.Object, ByVal e As DevExpress.XtraBars.ItemClickEventArgs) Handles BarButtonItem6.ItemClick

Dim 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?

Me.Hide()
e.Cancel = True

I want to do something like when click on the close button, a message box will pop up and if yes, close it else remain in the same form. But the following coding seems only consider one side while the other side is ignored.
Style = MsgBoxStyle.DefaultButton2 Or MsgBoxStyle.Question Or MsgBoxStyle.YesNo
Check = MsgBox("Do you want to quit?", Style, "Exit confirmation")
If Check = MsgBoxResult.Yes Then
Application.Exit()
End If

Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?

Based on our tests primarily done in VB.NET in VS2010 it seems that when you close a WinForm the "RowValidating" event of the DataGridView on that form behaves differently depending on whether the form is MODAL or NON-MODAL. What we did was open the form (MODAL and NONMODAL) and changed a value of a cell and then immediately clicked the "X" to close the form. It looks like the "RowValidating" event DOESN'T fire if the grid is on a MODAL form but it DOES fire when the grid is on a NON-MODAL form. We can't figure out why that is... Is this a known bug in .NET?

I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.

I never did custom events and would like to make a sub procedure execute via a custom event from another form that does not have the custom event defined. For example I would like to raise the event from my ok button in one form and have the event in the other form execute. How to set this up using code examples?

I have googled high and low to find an answer to this but I must be searching wrong.I have an application which has a listview displaying some items that are stored in a SQL Compact database. I am using a second form to add new items to this list directly into the database.When the second form closes I want to call the sub in my first form to refresh the list from the database.
How can I get it to fire the form1 sub routine on the close event of form2
