Hi,

I am working on a VB.Net project created by other people. The project is a
window application.

I have the following questions:
(1) What do the following codes mean:
Me.Close()
Me.Dispose()

(2) How do I prevent a window form from being closed?
In VB 6, I will do cancel = false in the form_unload.

(3) How do I determine the application verion at runtime.
In VB 6, I can do app.Major & "." & App.Minor & "." & App.Revision


TIA

Close the window (I'm assuming Me is a Form class).
Me.Dispose()

Dispose the window resources (closing internal Window Handles and suchlike)
(2) How do I prevent a window form from being closed?
In VB 6, I will do cancel = false in the form_unload.

Set e.Cancel = True in the Form.Closing event.

This code means that the form currently executing is closed and disposed.
Disposing is not necessary if the form is shown by calling its 'Show'
method, but it's necessary when calling 'ShowDialog'. In the latter case I
would not call 'Dispose' inside the form. Instead the user of the form
should call 'Dispose':

\\\
Dim f As New FooForm()
f.ShowDialog()
f.Dispose()
///

\\\
Imports System.ComponentModel
..
..
..
Private Sub Form1_Closing( _
ByVal sender As Object, _
ByVal e As CancelEventArgs _
) Handles MyBase.Closing
If...Then
e.Cancel = True
End If
End Sub
