VS 2008 Detect Windows Shutdown/Logoff?

Jun 20, 2010

I have an application that starts from Sub Main and I need to run a sub when the system is about to shut down, restart or logoff so it can save it's settings. I found some code on google:

Imports Microsoft.Win32
Public Sub Main
AddHandler SystemEvents.SessionEnding, AddressOf OnShuttingdown

[Code]....

But it doesn't seem to work, Windows shuts down yes but when I re-start the vm and run the app it opens with the old settings, not the ones that I changed before I shut down the vm. Anyone know of a way to do this or to fix the code above, I don't think my OnShuttingdown event is being handled.

Detecting Shutdown, Logoff, Restart, Sleep

Dec 25, 2007

What i wish to find is a message or the like that I can use to detect between specific 'shutdown' like events, ie: I wish to be able to find the difference between a shutdown, restart, logoff and sleep initiation.

The problem i have found (as displayed below) is using oClosingEvent.CloseReason the return types provide no further information other then the WindowsShutDown constant (the others are obviously irrelevant in this case).

Private Sub frmMain_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Dim oClosingEvent As System.Windows.Forms.FormClosingEventArgs

Control Ordering Of Shutdown In Windows

Sep 7, 2011

My main Application A starts a 3rd party Application B that runs as a console application. So I don't have access to the Application B source code. When specific things happen in Application A, I can properly launch a vb.net Application C that I built, which properly shuts down Application B, by sending a Ctrl-C signal to it, the same as hitting Ctrl-C in a console window. But I cannot have this occur on Windows shutdown because Application B shuts down on its own before I even have the chance to launch Application C to shut it down. Is there a way to keep some kind of control over Application B when I launch it, or any way to have it be last in the shut down of programs in Windows?

Trigger Program Action During Windows Shutdown?

Feb 10, 2009

I am designing a program that will show a reminder form when the computer is shutting down. (The reminder is to go outside and get the Bluetooth gps aerial.) I have tried using the formclosing event, (triggered by windows shutting down) to flash the form up on the screen using windowstate = normal. (At loading, the form windowstate = minimised). This did not halt windows shut down and the form was only on the screen for a fraction of a second before windows shut down. Can I trap windows shutdown until the form btn_Yes has been selected?

I think this msdn library article is talking about this. [URL]

I have looked at the enumprocess api, but this is quite a bit outside my current knowledge level. From what I have read, enumprocess would be suitable as we all run the same program on our laptops and I could check for the change of state of that program. Eg. �OK, program A is closing, the computer must be about to shutdown, so flash up the reminder form.�

I am developing a vb.net media application using Windows Media Player which is working fairly well. However, I am having problems where the Function key handler will stop working after doing anything on the media control panel, i.e. mute, move the slider etc. So long as I don't touch the panel everything continues to work. I'm using the function keys to pull up menus for selecting other media and if I do anything with the control panel I can no longer display the menus.
