There is another factor. If one has certain events on the execution
stack, one can not use SetFocus. That will throw an error
2012 ("Cannot call SetFocus from within a When, Valid, RangeHigh or
RangeLow event.")

You can work around this limitation, in VFP 9 at least, by RETURNing
to the control/object that you want to set focus to like so:
<some code that doesn't pass your validation test but you want to
let the user go somewhere else>
RETURN thisform.myControlToSetfocusTo
This is documented in the VFP 9 help
"In Visual FoxPro 9.0, the SetFocus method is not supported in the
When Event, Valid Event, RangeHigh Event and RangeLow Event events.
However, you can include a RETURN Command with an object name
(RETURN <ObjectName>) in these events to set the focus to another
control. If a RETURN command with an object name is included, the
focus is set to the control specified with <ObjectName>."
But what does that do for the validation on that control? You
have bypassed it with that return, right? What if you still need it?
Sincerely,
Gene Wirchenko
