Listen For The 'End Sub Event'?

This is my first post, so hopefully I'm asking it in the correct place.

Currently I have two subs where the first calls the second.

Sub Sub1()
'some code
Call Sub2(x)
End Sub
Sub Sub2()
'some code
End Sub

This means that Sub1 does not end until after Sub2 is complete.I need to have Sub2 run after Sub1 has ended. In my case Sub1 is triggered from an application event, so calling the two subs from another 'parent' sub would not work.Is there a way that I can listen for the 'End Sub Event' of a sub?I am currently working in VBA but will be heading to .net shortly so I'll take whatever flavour of code people can help with.
