Try running this code:
quit && quit Foxpro
DEFINE CLASS MyClass as Custom
CREATE CURSOR DummyCursor (name c(10)) && create a cursor
SELECT DummyCursor && try to select the cursor just created
What happens and why? On my machine, I get an error saying Alias ‘DUMMYCURSOR’ is not found.
You can see this behavior if you run the code in my prior post (Find which DLLs in your system are rebased) and then close VFP
One would expect that when the Quit occurs, the VFP process shuts down. This means releasing the public MyClass instance, which fires the destroy event.
The destroy event tries to find the cursor, but it has already been destroyed.
Apparently, probably for close to 15 years, the database engine shutdown code runs before the object manager shutdown.
Have you run into this issue before? Have you worked around it?
