I have an vb.net application that is a module that uses a "application.run"
in the sub main to start. There is no form involved (just a system tray
icon)
How can you detect when the application is being closed? It is easy enough
if the user selects "exit" from this tray icon but how can you detect if
Windows is closing the program down? Normally I would simply do something in
the Form.Closing event but without a form how can you determine that the
application is being closed by Windows? 12 17017
Just call Application.Exit

Application.Exit simply exits the program. I want to know how to detect
that Windows is telling my application to shut down. For example when
Windows is shutting down or restarting it will close all running
applications. I want to know how to detect that event when there is no form
in the application.

a long time ago, fergus suggested this to me...and it works just fine...
somewhere in your initialisation code:
either event will work just fine, but read the differences so you know which
is most appropriate for what you want to accomplish.
AddHandler ( _
SystemEvents.SessionEnding, _
AddressOf ShutDown.OnShuttingDown _
)
AddHandler ( _
SystemEvents.SessionEnded, _
AddressOf ShutDown.OnShutDown _
)
put the following class somewhere
Public Class ShutDown
Public Shared Sub OnShuttingdown( _
sender As Object, _
e As SessionEndingEventArgs _
)
e.Cancel = True 'only set if you turn down the shutdown request
Console.WriteLine ("Shutting down - Reason is " & e.Reason)
' your code here to clean up before exiting
End Sub
Public Shared Sub OnShutdown ( _
sender As Object, _
e As SessionEndedEventArgs _
)
Console.WriteLine ("Shutdown - Reason is " & e.Reason)
' your code here to clean up before exiting
End Sub
End Class
i'll be happy to help you if you can't figure out how to incorporate this
snippet into your application.
hth,
me
That looks good but the "AddHandler" lines simply say "syntax error" in
vb.net. I've added them to the top under the variable declarations and
within the sub main but they always show syntax error.

once again herf, it is you who needs to remove something...your head from
your ass. the syntax is NOT a problem. if you knew what the hell you were
talking about, you know the problem was *where* the op placed this code.
why are you an "mvp" again?

Again wrong. The code cannot be compiled because of the braces. You are
discrediting yourself.
From the VB.NET Language Specification:
| AddHandlerStatement ::=
| AddHandler Expression , Expression StatementTerminator
| RemoveHandlerStatement ::=
| RemoveHandler Expression , Expression StatementTerminator
