I want to logout the user from a remote session when the desktop is

There seem to be various ways of catching these events:
- WTS API
- ISensLogon Interface (SENS)
- Using Service Control Manager (SCM) Notifications (only for services?)
- Winlogon Notification Packages (deprecated and removed from Vista)
I currently am trying the following (using WTS API):
if "wxMSW" in wx.PlatformInfo:
import win32ts
win32ts.WTSRegisterSessionNotification(self.GetHandle(),
win32ts.NOTIFY_FOR_THIS_SESSION)
This does not throw errors at me, but now I am baffled as how I can
catch the WTS events.
Your window will now receive WM_WTSSESSION_CHANGE messages. There's a
sample at http://wiki.wxpython.org/MonitoringWindowsUsb that provides a
wxPython mixin class that allows you to capture arbitrary window
messages. When using this, you'd just say:
self.addMsgHandler( WM_WTSSESSION_CHANGE, self.onSessionChange )
self.hookWndProc()
def onSessionChange( self, wParam, lParam ):
...
WM_WTSSESSION_CHANGE is 0x02b1.
Also, is this the appropriate method as the docs state that it
requires Windows Terminal
Services loaded (which I don't have running).
Starting with XP, all systems run with Windows Terminal Services
enabled. That's how fast user switching is implemented, among other things.
Tim,
that's great, it works like a charm.
Thanks a lot!
Ron
