When I execute a statement such as
Set MyObject = Nothing
is there a particular function inside the class that is invoked (i.e. that I can use as a destructor), to do things like clean up arrays, disconnect开发者_StackOverflow from databases, and so forth?
Analogous to Class_Initialize
, the constructor, there's also a destructor:
Sub Class_Terminate
... ' Put your destructor code here '
End Sub
This method is executed as soon as the reference count of this object reaches zero, i.e., when all variables that reference this object have gone out of scope or have been set to set to something else (e.g. Nothing
). Thus, Set MyObject = Nothing
will only call the destructor if MyObject
is the last variable referencing this object.
No. VB6 does not provide any mechanism to the programmer to write something explicitly. What a programmer can do is Set MyObject = Nothing
and VB will take care of the rest.
UPDATE:
One can use the Class_Terminate
to handle this
