ByVal, ByRef

[ccc]

Okay, I know what byVal and byRef do, ByVal passes a copy of an object, and ByRef passes the actual object, but lets say I have this code:

 

Class myTest
Event myEvent(ByVal sender as myTest)
sub FireEvent()
RaiseEvent myEvent(me)
end sub
End Class

sub RunTest()
dim mTest as new myTest
addhandler mTest.myEvent, addressof del_myEvent
mTest.FireEvent
end sub

sub del_myEvent(byval sender as myTest)
RemoveHandler sender.myEvent,addressof del_myevent
end sub

 

Will the object mTest's handler be unassigned correctly? Or since i've passed a copy of the object, the original will still fire again? Should I just stick to writing everything byref instead? My application seems to eat up alot of memory, because something is getting stuck and not used. It uses a similar structure to the code above. Any tips?

 

Any help would be appreciated. Thanks. :confused:

Your class is a reference type, so it'll always be passed by reference. Only value types (structures and the primitives) can actually be passed by value.

Thank you, that really cleared everything up for me.
