I built myself a .Net 2.0 application to use the ActiveS COM Wrapper from KhaosLabs. Support for ActiveS seems to be on hold, so I rebuilt my application to use Skype4COM (to educate myself).

Using ActiveS, my event handler for oSkype.APIStatusChanged automatically fires when Skype is shutdown or restarted.

Using Skype4COM, my event handler for oSkype.AttachmentStatus fires when Skype is shutdown, but does not appear to fire when Skype is restarted.

Am I wrong to use .AttachmentStatus?
What is the correct way to handle the event?

I found the problem.

Skype4COM returns .apiAttachSuccess on the initial connection, but returns .apiAttachAvailable if Skype is restarted.

ActiveS returns .apiAttachSuccess each time it attaches to Skype.
