i'm using pdoxw 5.0. Is there a way to update the record if a keyvoilation 
occurs? I'm not using a tcursor, if so I guess I could use tc.updaterecord.
But in pure forms mode, how would I  1) determine a key violation and 2) 
after decising the existing record just needs to be updated, how to 
accomplish the task.
thank you for any help you can offer.
