>>One tiny thing however. I don't agree with Fabio about the use of 'm.this.Value'. It should be 'this.value', so without the mdot. The mdot is complicating things here and does not add quality to the code. Fabio, you are giving a bad example and the risk is that it may become widespread to even specify the mdot when refering to this, thisform and the like. I know you can prove that 'this' could also be the name of a field, but that's really too academic.

The issue is for Alias, not for a Field.
When you write this.xxxx VFP search for a Alias=='this'
into the current datasession.
