Update main form control from subform
|
| |
I have an Access database with two tables "Main" and "Rafflenumbers", also a main form (for names etc) and a subform (for numbers assigned). I put an unbound control on the Main form which I want to have updated with the last number added to the control on the subform.

Examples of SQL anomalies?
|
| |
Before I waste a big chunk of next week, does anyone know of any docs on the web that attempt to gather together examples of anomolous behaviour in standard SQL?

|
| |

I understand this depends on the application/domain/type of data, but,... more »

Tili- ja vastuuvapaus, tilinpäätöksen vahvistaminen
|
| |
Aika huvittavaa, että tiedotusvälineet ovatr kiinnostuneet vain Kallin taustamaksajista, miksi? Miksi ihmeessä ei oteta esille esim. Anne Holmlundin ja vaikka nyt Paavo Lipposen kaltaisten kiistatta tiedettyjä ydinalan madonlukukytköksiä SDP:n vaalien alla ja noin?
