• Visual Studio What does VBProjectProperties3.MyApplication return?

I'd like to add code to a couple of application events (startup and shutdown) so I need to generate code as if the user has clicked "View Assembly Events" button on the project properties ...Show All

I have checked sp_lock myprocessid and I've noticed there are a lot of exclusive locks on different objects. Using sp_who I could not see any deadloc ...Show All
