Check the Command pattern in Gof books, MFC almost use it in
the same way:
SubWidget in the dialog will catch it firstly, it will
forward it to Parent window(the dialog) if *request is not
for it or no handler defined.

This procedure runs recursively, until one handle it or pass
it to application object. Application will omit unknown
command by default

write a code for this. serial_number contained in the header of the file will be read , if this serial number is less than a previous serial number within a successfully processed file, or is the same as another serial number within a successfully processed file, or if the field contains anything other than 7 digits, then the file must error with the reason ‘Invalid SERIAL_NUMBER’.
