I am using Access as the front end and using a SQL database and some VB 6.0 code.

I have a form that is using a Query that asks the user for a "VehicleID" and a "Date".
Once the record is retrieved the user can add additional info or edit info and then there's an Update Record command button. The values are writing to a db table in SQL. Once the user hits the update button the error message "The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time". I am the only user that is using this right now because it is still in the testing stage. So I don't understand why I'm getting this error. Could it be in my code? My code is below:

Private Sub cmdAddRec_Click()
On Error Go to Err_cmdAddRec_Click


Dim rstTrans As New ADODB.Recordset
Dim fld As ADODB.Field
Dim strField As String
Dim Msg, Response


Msg = "Do you want to update another record?"

Sqlstmt = "SELECT * FROM dbo_tbl_HR_Shuttle WHERE VehicleID = " & Form_Daily_Vehicle_Tic_Sheet_Data_Form!VehicleID

rstTrans.Open Sqlstmt, CurrentProject.Connection, adOpenKeyset, adLockOptimistic

rstTrans!DateModified = Now()
rstTrans!UpdateUser = gUser

Me.Refresh

rstTrans.Update

Response = MsgBox(Msg, vbYesNo)
If Response = vbYes Then
'MsgBox ("result is yes")

DoCmd.Close

DoCmd.OpenForm "Daily_Vehicle_Tic_Sheet_Data_Form"
Else
DoCmd.Close
End If

rstTrans.Close

Set rstTrans = Nothing

Exit_cmdAddRec_Click:
Exit Sub

Err_cmdAddRec_Click:
MsgBox Err.Description
Resume Exit_cmdAddRec_Click

End Sub

Please give any advice that you can.
Thank you:confused:

Do you know what line is causing the error? Also, I don't see why you are using ADO. You coould just as easily time and people stamp the record using controls on the form.
