Edit record before update in query subform Access VBA -


here have:

two tables:

  • tbla: index, date_time, user_name, event, product_serial_number

  • tblb: tbla_index, date_time, user_name, event_tag

the field event_tag used classify different characteristics event see youtube videos, hence, many 1 relation.

i have main form information of tbla displayed such user_name , index. have subform event_tag field displayed in datasheet view control source query filtering index taking tbla.

i know in queries can add records typing in blank record @ bottom (if enabled). want able type in new event_tag record specific index in tbla. wondering possible programmatically edit record being inserted table before updated?

for example, type in blank record @ bottom of subform defective motor , use vba code take date_time computer , index/user_name controls in mainform , add complete record, insert tblb.

i hope enough example show trying do. appreciate feedback if can direct me how solve this, or if there better way.

thanks

use "onbeforeupdate" event subform. within event

txt_date.value = now() txt_username.value = string

and on
