FieldByFullName Method
The FieldByFullName method finds a field object that matches a fully specified name:
FieldObject = FrameForm.FieldByFullName(fullname =
varchar(256))
This method checks through the list of fields contained within the frame to find a field with a name that matches the name you specify.
This method has the following parameter:
fullname
Uses dot notation like that used in the FieldObject.FullName attribute (for example, AddressInfo.Street or employees[*].emp_no). This name must include the names of all named composite fields that are the ancestors of the desired field. If no field has a matching name, the method returns null.
