>This won't work. It isn't stateless. A better way is to have the UI send the data to a Save() method. Save() calls Validate(). Validate() returns a text string that contains the messages to be displayed for all data that fails validation. If empty, all data is valid and Save() calls the appropriate Data objects to save the data and then returns. If data fails validation, the text string is returned from Save() to the UI for display.

One more thing. You could return an ADO recordset that had one row for each validation failure, but you would RETURN that from the Save() method. You don't want to call another method to get it.
