[python-win32] How to delete a dispatched object

[Mark Hammond]

As soon as the last reference to the PyIDispatch object goes away, the COM
object is released.  Unfortunately, neither Python nor COM offer a way to
actually destroy an object - they are both independently reference counted
so the only option available is to drop all references being held.

 

In Python, this means that:

ob = win32com.client.Dispatch(.)

del ob

 

would cause the object to die (as would assigning 'ob' to something, such as
None), but:

 

ob = win32com.client.Dispatch(.)

ob2 = ob

del ob

 

would not - nothing you can do to 'ob' can help you now - you must also
remove the reference in 'ob2'

Hi

 

I am wondering how could I delete an dispatched object? Do I just delete the
reference to that object? Does python garbage collector take care of
everything after I delete the reference? Is there any method which I could
use to delete a dispatched object?
