The following code fragment shows how to use the SubmitChanges method with an RDS.DataControl object.
To test this example, cut and paste this code between the <Body></Body> tags in a normal HTML document and name it ADCapi6.asp. ASP script will identify your server.

The following code fragment shows how to use the SubmitChanges method with an RDSServer.DataFactory object. You may want to submit changes to the DRSServer.DataFactory if you are working on a Visual Basic project where the RDS.DataControl isn't used. To create this project, open a Visual Basic form and place on it a List box (List1), two Text boxes (txtConnect and txtGetRecordset), and two Command buttons (cmdGetRecordset and cmdSubmitChanges).
Dim ads As Object ' RDS.DataSpace object Dim adf As Object ' RDSServer.DataFactory object Private Sub UserDocument_Initialize() Call Form_Load End Sub Private Sub Form_Load() txtConnect.Text = "Dsn=pubs;Uid=sa;Pwd=;" txtGetRecordset.Text = "Select au_lname from authors" End Sub Private Sub cmdGetRecordset_Click() Dim Server As String Server = txtServer.Text ' Create RDS.DataSpace using CreateObject Method of RDS.DataSpace Set ads = CreateObject("RDS.DataSpace") Set adf = ads.CreateObject("RDSServer.DataFactory", Server) ' Populate ListBox with Recordset MousePointer = vbHourglass Dim objADORs As Object Set objADORs = adf.Query(CStr(txtConnect.Text), CStr(txtGetRecordset.Text)) List1.Clear While Not objADORs.EOF List1.AddItem objADORs(0).Value objADORs.MoveNext Wend MousePointer = vbNormal End Sub Sub cmdSubmitChanges_OnClickadf.SubmitChanges " Dsn=pubs;Uid=sa;Pwd=;",_objADORsEnd Sub
