Returning .F. will display the VFP message and retain focus in the control. Returning 0 will NOT dislpay the VFP message but it will retain focus in the control.

Pablo,

Using LostFocsu to determine whether the user will be allowed to exit a control is misuing the LostFocus event. There is an event for that purpose, Valid.

Your question asked which one I thought is better, not which one will wokr. They both will work, but I find using the events as they were intended is a better way to work.
