object.PropertyX(parm1) = value object.PropertyY(parm1, parm2) = valueVFP treates these parameters as array indexes and apparently does not allow for multidimensional arrays: PropertyX can be set inside VFP (I suppose within VFP limits, which could be another problem) but PropertyY doesn't. Is there any way of setting the value of this kind of properties, without resorting to a FLL proxy?
