Order of base class "OnWhatever()" calls

[Jim Matheson]

Hi there,

When overriding form/control functions like "OnLoad()", "OnFormClosed()",
etc., should the base class version be called before or after your own code.
The docs say nothing about this nor give any guidance. It probably depends
on the function itself so are you supposed to determine this. Thanks.

Jim,

etc., should the base class version be called before or after your own code.

Unless the documentation explicitly says something about this, it's up
to you to decide if you want your own code to run before or after the
base class'. Sometimes, for example with painting, it makes a
significant difference (who paints over who), but you can't say that
one way is more correct than the other.

Ok, thanks for the feedback.
