I want to detect when employees in our company are shutting down or restarting their computers. Is there a Windows API Call that will do that which I can hook onto? I found WindowsExitEX but it actually restarts the computer!

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 making a program that takes a time input from the user or a countdown amount and when that time comes it will shutdown or restart or log off the computer. I know how to make the timing code and everything else but i don't know how to shutdown or restart or log off.
View 1 RepliesI'm trying to create a way for the User of my application to Log Off, Shutdown, or Restart the PC.
The idea is that User can more quickly access these options from my application and if they choose, force these actions instead of waiting for the OS to respond.
Here's how I'm trying to do it:
CODE:
Log Off works just fine. It's shutdown and restart that doesn't work. From the research that I've done, the Consts seem fine and the function obviously works correctly because Log Off works. I am running the application as an administrator, so that should affect it.

View 5 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).

My app is having problems shutting down in a WinXP environment. I thus want to simulate a Windows shutdown in the VB.Net IDE and then debug my code but is this possible?
View 1 RepliesI'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
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?

View 5 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.�

In an app I am writing I need to be able to display the current settings of the following:- Windows "automatically restart on error" setting from advanced, startup and recovery section Paging file size and whether it is custom size or set to system managed Is this at all possible? perhaps VB has a function to do so I cannot find, or perhaps I can do by querying a registry value?
View 6 RepliesI spent some time with data modems till I realized it's a voice modem that I'm going to need in my application. I see that there are some other commands for a voice modem, although nothing very elaborate. I would imagine you make the call as you would in a data modem ATDT etc and it looks like there is really just one command to send audio...
AT+VTX
AT#VTX
Not sure what this is all about except maybe just different standards? Still not sure about how to detect when the call is answered though. I won't be talking to another modem. Maybe the serial port itself has a pin change or something? You would think there would be a bit "somewhere" that the modem would generate when it quits ringing. I may have build my own outboard box to do this. (easy enough -- probably more reliable too -- modems sure need rebooting a lot it seems).
Here is the goal though --Voice modem calls out, call is answered, and I inject my audio from the PC sound card for a minute or so and then tell the modem to hangup.

I know you can do it with an WMI event or overriding WndProc and looking for the right messages, but i was wondering if there wasn't something hidden in the net framework that makes this task easyer.
