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

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.
I am trying to capture SHUTDOWN and LOGOFF Events, so that I can be alerted when my process stops. The below code works in detecting these events. I am trying to get it to release the monitoring of the system events after the email has been sent, Being newer to VB, I am not sure how to do this. I copied this code from another google forum.

I'm making a screensaver with the added option of shutting down/oggingoff/hibernating/sleeping at a user-defined time. Now, I'm fine for all my code except for the scripts for these events.
View 1 RepliesWhat 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

View 1 RepliesMy 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?

View 2 RepliesI 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 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 working on moving applications from Windows 2000 to new server Windows 2003 R2(64 Bit). I noticed that there are some VB programs and config files for those programs have been placed in Windows 2000 Registry. Some other applications are using them from different servers.Why do we use registry here? How can i move these to registry in windows 2003? Can I just move these or do I have to write VB programs to place them in 2003 registry?
