[AccessD] Classes, Recordsets, and problems inbetween

Gustav

With true OO with inheritance, a function that is available in the parent
class can be replaced in the child class so that whatever functionality the
parent's function provided can be overriden.  Overloading is a method of
performing this processing in the class, but further allows the parameters
passed in to the class to be replaced as well.  For example FunctionA in one
child class may accept an integer, in another it may accept a real.  Since
the parameters are different, the correct child class can automatically be
selected by the runtime based on the type of data passed in.  If I am
passing in an integer I must be intending to use that specific child class,
whereas if I pass in a float I must intend to use this other child.

Since Access only has interface inheritance, it doesn't implement any of the
OO stuff of more powerful languages (such as VB.Net), and all discussions of
such capabilities is moot.

Hi John

> Overloading definitely is not supported in Access VBA.

Just thinking logically:
If that was the case it wouldn't be overloading?

(Guess I'm showing that I have no idea of what overloading in VB is
about).
