I have written some coding to add a new row to an existing data table. After clicking the submit button I get following error. "Update requires a valid InsertCommand when passed DataRow collection with new rows." Please tell me what the additional code I should add. The "add" method is called after a user clicking the submit button. I didn't include the HTML stuff here. Here is the code, <script runat="server"> sub add(obj as object, e as EventArgs) dim objConn as new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Inetpub\wwwroot\scms\database\scms.mdb") dim objCmd as new OleDbDataAdapter("select * from services", objConn) dim ds as DataSet = new DataSet() objCmd.Fill(ds, "services") dim dr as DataRow = ds.Tables("services").NewRow() dr(1)=txtServiceName.text dr(2)=txtSinhalaShortTag.Text dr(3)=txtTamilShortTag.Text dr(4)=txtEnglishShortTag.Text ds.Tables("services").Rows.Add(dr) objCmd.Update(ds, "services") end sub </script> Please help me. I can't figure out what to do. vbgaya.
