Detecting if application was started on login from startup folder

[Guest amohr]

Basically I need some way for my application to be able to detect if

explorer launched it in response to it being in the startup folder and

the user logging in. I would like to be able to distinguish between

explorer launching my application at startup, and the user clicking

the link in the startup folder (this precludes using a simple command-

line parameter).

 

I'd like something similar to keyAELaunchedAsLogInItem

kAEOpenApplication AppleEvent (http://developer.apple.com/

documentation/Carbon/Reference/Apple_Event_Manager/Reference/

reference.html#//apple_ref/doc/c_ref/keyAELaunchedAsLogInItem).

 

The only thing I saw close to this was the WM_WTSSESSION_CHANGE window

message, however it seems apps launched from the startup folder don't

receive the WTS_SESSION_LOGON in time, and it doesn't seem like it

would work reliably anyway.

 

ideas?
