If ALL controls are placed in the form (not in some container)
The you could use this (in Init event of the form):

FOR EACH oControl IN thisform.Controls
    IF PEMSTATUS(oControl, "GotFocus", 5) AND;
       NOT INLIST(UPPER(oControl.Name), PUT THE NAMES OF CONTROLS YOU WANT TO EXCLUDE IN UPPER CASE HERE)
       BINDEVENT(oControl,"GotFocus", thisform,"PopulateListBox", 1)
    ENDIF
NEXT

If you use some container in that form (PageFrame, Container, etc) you should do this as a method in the form and call it recursively for each container.
