Just do not name the array as native property.
The same is valid for Visible, hWnd etc.


In VFP 8 you coud use:

lbIsArray = .t.
TRY
    leDummy = thisform.Visible[1]
CATCH
   lbIsArray = .f.
ENDTRY

NOT TESTED AT ALL!!!

Later:
GRRRR, Even this gives me .T. t the end

Later than previous later::-)))

lbIsArray = .t.
TRY
    leDummy = ALEN(thisform.Visible)
CATCH
   lbIsArray = .f.
ENDTRY
