I have a data control setup on the form with a couple of bounded textboxes. I have two tables in the Access database. The bounded textboxes write directly to one of the tables. But I want to be able to update a record in the other table associated with the current record that was editted.  How do I do this as there seems to be no events for the data control to do this?

hi,
u can write the following code in the Save button of your form.


dim db as database
dim rs as recordset

' write code to open the database containing the other table

set rs = db.openrecordset("select * from OtherTable where relatedfld = '" & txtrelatedfld &"')
rs.edit
rs!fldtoupdate = txtval
....
rs.update
rs.close

The 'normal' (DAO) data control doessn't have those features. The Microsoft Ado Data Control does have events like:

Adodc1_RecordChangeComplete(ByVal adReason As ADODB.EventReasonEnum, ByVal cRecords As Long, ByVal pError As ADODB.Error, adStatus As ADODB.EventStatusEnum, ByVal pRecordset As ADODB.Recordset)
Adodc1_RecordsetChangeComplete(ByVal adReason As ADODB.EventReasonEnum, ByVal pError As ADODB.Error, adStatus As ADODB.EventStatusEnum, ByVal pRecordset As ADODB.Recordset)
Private Sub Adodc1_WillChangeField(ByVal cFields As Long, Fields As Variant, adStatus As ADODB.EventStatusEnum, ByVal pRecordset As ADODB.Recordset)
Private Sub Adodc1_WillChangeRecord(ByVal adReason As ADODB.EventReasonEnum, ByVal cRecords As Long, adStatus As ADODB.EventStatusEnum, ByVal pRecordset As ADODB.Recordset)
Private Sub Adodc1_WillChangeRecordset(ByVal adReason As ADODB.EventReasonEnum, adStatus As ADODB.EventStatusEnum, ByVal pRecordset As ADODB.Recordset)

In other words: using the ADODC will solve your problem.

If the fields you want to update are the same, use "Enforce Referential Integrity".  For example, you have Table1 and Table2, both have a field called Index and the two tables are joined by this field.  In Access, create the relationship, choose Enforce Referential Integrity, and then Cascade Update Related Fields.  That way, when you change Index in Table1 from 1 to 2, it does the same in Table2.  By the way, the fields that would be linked must be part of the primary key of each table to use Referential Integrity.
