I'me developing and application where I need to detect logons and then display something when somebody has actually logged on. Note that the customer has specified 'logon' as any time a user goes through a signon screen (thus a workstation unlock counts as a logon here).
This is going to be used in Vista in the future, so Winlogon Notification Packages seem to be out, as does the GINA approach.
My readings imply that I have two ways to go:
- Service Control Manager Notifications (which seem to provide lock/unlock/logoff/logon states)
- the System Events Notification Service (which provides ISensLogon methods for the four above, plus others such as StartShell and StopScreenSaver).
Has anybody used or played with the above, and can they give comments on which is the best way to go? Note that the application will have to be able to look across different logons, so I suspect it will end up as a service. On the other hand, I'm still at the thinking stage so nothing's cast in stone.
Any and all comments welcome!
