Hi, Antonio
I am not sure about this first part.
But as for the grid situation, just before you do the zap, set the grid.recordsource = "". Do what you need to do to the table, then set the recordsource back to the table.
That should preserve your grids column order on the form.

HTH,

>I have one situation that I need to update a table with buffermode = 5 (optimitisc table buffer), but sometimes a I need to do ZAP in this table. So, in this case I need to change do buffer mode to 0 (none). When I change the buffer mode property I receive a messsage number 1739. "Property setting will not take effect until data environment reloaded".
