[AccessD] Two “Related” List Boxes on a Single Form

I have just started to experiment with Parent-Child List Boxes on a single
form.  I have developed a method that works, but I would like to know if I
am on the right track.   Perhaps there is a better method that people with
more experience use.



For experimentation purposes, I am using a simple example.



The Parent List Box is set up for “Country” – Only two countries are in it,
 “Canada” and “US”



The Child list box is set up for Provinces/States





I have set up this function

~~~~~~~~~~~~~~~~~~~~~~

Global Country_Selected



Function Function_Country_Selected()



Function_Country_Selected = Country_Selected



End Function

~~~~~~~~~~~~~~~~~~~~~





In the Parent List Box there is a  “On Click” Event Procedure with this code



Country_Selected = List0



(Plus code to Requery the Child List Box)



~~~~~~~~~~~~~~~~~~~~~

 In the Criteria in the Query for the Child List Box I have this line



Function_Country_Selected()



~~~~~~~~~~~~~~~~~~~~~



Again, this method seems to work.  I am just curious if this is the approach
that others use, or is there perhaps a better method.



Thanks,

Brad
