Question

I have an Microsoft Access 2003 ADP, which uses a bound “main” form with several bound continuous-style subforms. They all utilize disconnected Recordsets via a helper class.

Several users have noticed the same strange behavior: they add/edit a record in the continuous subform, they leave the record (committing the edit to the Recordset), they lock the computer (Ctrl+Alt+Del), they unlock the computer, they go back to the form, after about 5 seconds it flickers and revert to the original unedited state.

I’ve been able to reproduce this following the steps above, further, after making a change in my form, bound to a disconnected Recordset, I went to SQL Server and changed a value. After the lock/unlock computer routine, the form flickers and refreshes, and the NEW value I just entered in SQL Server appears.

It’s as if after about 5 seconds, my disconnected Recordset is reconnecting (on it’s own) and requerying the Recordset.

I realize I’m not giving a lot of information here, but has anyone encountered an issue with disconnected Recordsets reconnecting and requerying? Or at least have an ideas of where I could start debugging?

I have the ADP and SQL script to create the database if someone would like to recreate this in their environment.

Here’s how I’m creating the disconnected Recordset:

Dim cnn                 As ADODB.Connection
Dim stmTest             As ADODB.Stream

Set cnn = New ADODB.Connection
cnn.Open Application.CurrentProject.AccessConnection.ConnectionString

' Create recordset and disconnect it.
Set mrsTest = New ADODB.Recordset
mrsTest.CursorLocation = adUseClient
mrsTest.Open "SELECT * FROM [tblChild] WHERE ParentID = 1" _
    , cnn _
    , adOpenStatic, adLockBatchOptimistic
Set mrsTest.ActiveConnection = Nothing

cnn.Close
Set cnn = Nothing

' Copy recordset to stream in memory.
Set stmTest = New ADODB.Stream
stmTest.Open
mrsTest.Save stmTest, adPersistADTG

' Bind form to disconnected recordset.
Set Me.Recordset = mrsTest

' Open a copy of the recordset from the stream.
Set mrsTest = New ADODB.Recordset
stmTest.Position = 0
mrsTest.Open stmTest

Answer 1

I wanted transaction like processing (Save and Cancel buttons) without
the tables being locked, in my multiple user system. For continuous
forms in Access to work, they must be bound to a Recordset.

You can use forms/subforms bound to temporary tables to achieve just this effect.
