Hi Walter,

>There is no difference in terms of achieving you're goal. I only was pointing out that domain checking can be done without the access and asign methods.

In that case, the bottom line is, for another developer using your classes or forms wants to change xProp, he sets it. If the value is totally off, you can give himw a property specific detailed message. Otherwise he would try it, find out the properties hidden, perhaps stumble accross the SetXProp method, than have to learn any syntax.
