How do you log off of Windows XP using VB.NET?

The ExitWindowsEx API Still works in .NET as far as I know.

Those examples don't seem to be working in vb.net

Does anyone know of any other examples?

An unhandled exception of type 'System.IO.FileNotFoundException' occurred in microsoft.visualbasic.dll

Additional information: File not found.

VB Code:

Shell("C:\WINDOWS\system32\RUNDLL32.EXE user.exe,Exit,Windows")

It dosn't do anything now.

Note: I changed "C:\WINDOWS..." to "C:\WINNT" because WINNT is my system directory. (I have Windows 2000 pro)

Well it acutly dose do SOMETHING but it doesn't log off, the progress indicator just goes for a seconnd.

this wouldnt happen to be for a virus or hack would it? it just sounds wierd if not what would you need that for?

the API Should still work...Make sure you changed the LONGS to Integers...

VB Code:

Declare Function ExitWindowsEx Lib "user32" Alias "ExitWindowsEx" (ByVal uFlags As Integer, ByVal dwReserved As Integer) As Integer

I was planning on writing a program that would log off my account if someone else was using it. The reason why I wanted a program for this is because I frequently leave my computer logged on to my user and my dad dosn't want other people on my login because I have higher security privalges then the other people who use this computer.

How would you know if someone was logged on as you?

I was going to use the filesystemwatcher.

oh...

little note , it's better you run it from bin dir so it wouldn't ask you whether you want to stop debugging the code or not !

thanks a lot for all the help. THe changing the Long's to Integers fixed it. Thanks a lot. I will let you all know when my program is finished.

do this

VB Code:

'in a module 
Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Integer, ByVal dwReserved As Integer) As Integer
Public Const EWX_LOGOFF As Short = 0
 
'in your form
Dim lresult As Object
lresult = ExitWindowsEx(EWX_LOGOFF, 0)  'close all programs and log on as a different user

Thanks,
It works now.
