Hi!

Use GetFLDState function just after INSERT and APPEND BLANK commands. For INSERT it returns 3 for all fields except used in the INSERT command. Despite these fields use default values, they marked as inserted only, not as inserted and modified (4 in GetFLDState). Thus, command for insertion to server contains only thous fields that are marked by '4' -> default values from table are not overwritten.

As opposite, APPEND BLANK marks all fields by '4' (inserted and modified). This cause all fields participated in INSERT underlying command during update of table, that overwrites default values.

If you want to guarantee your field to be updated in new record, user extra replace for it after INSERT command, or just include it into INSERT command for view.

The professional level of programmer could be determined by level of stupidity of his/her bugs

It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
