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

Detect An Unexpected Shutdown Within A Program And React To It In A VB Program?

Aug 14, 2009

I'm working on a web browser named Hyvar.NET and i'd like to integrate a form of shutdown detection into it.

Currently, it simply uses a tri-option setting to decide how it opens - like this

If My.Settings.LoadLastOnStart = True Then
frm.wbTab.Navigate(My.Settings.LastOpenedPage.ToString)
ElseIf My.Settings.HomeOnStart = True Then

[Code]....

Each variable is appropriately named for its job as you can see.

However, i want to change this to react to correct and incorrect shutdowns - unexpected and user instigated ones for example. I.E: if the settings variable for the detection contained 0x000000, it could indicate a clean exit and continue as normal with a new session, but 0x000001 would indicate an unclean shutdown and present the user with an option of reopening the last session or continueing as normal, like in IE 7/8

Im 100% sure this will require a windows API call

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.�

Logoff A Remote Session?

Aug 9, 2011

I have a distributed print control application that is done in a combination VB6 and Visual C++. The application launches at startup on a workstation and waits for a user to login. Once that happens, we track time in the session, along with how many print jobs the guy performs.

We have separate session SW that allows a person to add money to their accounts. The problem is that if there's an active session, typically due to the individual being logged into one of the above mentioned workstations, I can no longer ensure updates to the DB will be atomic.

I would like to have the money terminal send a log off command to the remote workstation session if it detects a user is currently logged in elsewhere. But I'm not sure if there's an existing API for this.

Detect When PDA (Windows Mobile) Is In Flight Mode

Aug 1, 2011

I need to produce an error display message when the Windows Mobile PDA is in flight mode. The user will need to pull and push data from a SQL Server server; however when in flight mode this is not doable and a message needs to be displayed. Currently the message that is displayed is:

A request to send information the the computer using IIS has failed. For more results please see HRESULT.

I am programming using VB.Net and I am fairly new to it. I have searched for the past week on the Internet and come across information suggesting that I use TAPI, however I do not know what to import, or where the "flight mode detection" code would go in my application.
