Question : Rolling back transactions in Access (using ADO, DAO, Access code, whatever)

I'm a SQL programmer, fairly new to Access...

I have an Access database that I created a form in, within the form, I want to run several action queries (to insert data, update data, and delete other data) over a series of 4 queries.  If any of them fail, I need to roll them all back.  I thought the ability to rollback would be inherent to Access 2000 but apparently not.

I tried to use ADO since I am familiar with that, but two problems:
1. ADO asks for the path of the file - that is really redundant since I am IN the database that I want to interact with, but I provided it the path anyway.
2. When I try to open the database that I am ALREADY IN,  it tells me that (80004005) "database has been placed in a state that prevents it from being open or locked"

Should I be using DAO?  Is there a better way to connect using ADO?  Can I use functions and calls inherent to VBA or A2000 that will allow rollbacks.

Thanks for your time.

Answer : Rolling back transactions in Access (using ADO, DAO, Access code, whatever)

DAO makes it very simple ...

Public Function TRANS()

Dim blnTrans As Boolean
Dim ws As DAO.Workspace

On Error GoTo ERR_TRANS

Set ws = DBEngine(0)

ws.BeginTrans
    blnTrans = True
    DBEngine(0)(0).Execute ...blah your SQL, dbFailOnError
    DBEngine(0)(0).Execute ...blah your SQL, dbFailOnError
    DBEngine(0)(0).Execute ...blah your SQL, dbFailOnError
ws.Committrans

EXIT_TRANS:
   Set ws = Nothing
    Exit Function
ERR_TRANS
   If blnTrans = True Then
      ws.Rollback
  End If
  Resume EXIT_TRANS
End Function
