Microsoft Access Sample Code | How to use ADO | ActiveX Data Objects

Function for using ADO (ActiveX Data Objects)

ADO (ActiveX Data Objects) is a language-neutral object model that expose data raised by an underlying OLE DB Provider. The most commonly used OLE DB Provider is the OLE DB Provider for ODBC Drivers, which exposes ODBC Data sources to ADO. In other words, ADO is a programming interface that allows you to communicate with data objects in your database using VBA code. This type of interaction can be very powerful and provide you some great flexibility in your Access Database. In order to use ADO, you must set a reference to it in your Access Application. The screen show below shows a project that has a properly setup reference to ADO:

After setting the reference, you can than use the ADO objects to interact with Data in your database and other databases depending on your connection setting. Note, the sample code below is just a sample and will not work in your Application unless certain changes are made to work specifically with your data objects.

Public Sub doADO() On Error GoTo doADOErr Dim myData As New ADODB.Recordset Dim conn As New ADODB.Connection Set conn = CurrentProject.Connection myData.Open "SELECT * FROM tblName", conn, adOpenForwardOnly, adLockReadOnly If Not myData.EOF Then With myData Do Until .EOF txtField = !DataBaseField1 .MoveNext Loop End With End If myData.Close conn.Close doADOExit: Exit Sub doADO: MsgBox Err.Description, vbOKOnly, Err.Source & ":" & Err.Number Resume doADOExit End Sub

The Microsoft Access ADO Database is a sample database that shows you a number of ways to use the the above function.

Please note that this is a template database. If it doesn't meet your needs 100% and you're unable to customize it yourself, let us know and we'll provide a quote to develop the customizations you need to get you exactly what you want in your ADO System.
