  <% ' Selected constants from adovbs.inc Const adOpenStatic = 3 Const adLockPessimistic = 2 Dim cnnExcel Dim rstExcel Dim I Dim iCols ' This is all standard ADO except for the connection string. ' You can also use a DSN instead, but so it'll run out of the ' box on your machine I'm using the string instead. Set cnnExcel = Server.CreateObject("ADODB.Connection") cnnExcel.Open "DBQ=" & Server.MapPath("xl_data.xls") & ";" & _ "DRIVER={Microsoft Excel Driver (*.xls)};" ' Same as any other data source. ' FYI: TestData is my named range in the Excel file Set rstExcel = Server.CreateObject("ADODB.Recordset") rstExcel.Open "SELECT * FROM TestData;", cnnExcel, _ adOpenStatic, adLockPessimistic ' Get a count of the fields and subtract one since we start ' counting from 0. iCols = rstExcel.Fields.Count %> <table border="1"> <thead> <% ' Show the names that are contained in the first row ' of the named range. Make sure you include them in ' your range when you create it. For I = 0 To iCols - 1 Response.Write "<th>" Response.Write rstExcel.Fields.Item(I).Name Response.Write "</th>" & vbCrLf Next 'I %> </thead> <% rstExcel.MoveFirst ' Loop through the data rows showing data in an HTML table. Do While Not rstExcel.EOF Response.Write "<tr>" & vbCrLf For I = 0 To iCols - 1 Response.Write "<td>" Response.Write rstExcel.Fields.Item(I).Value Response.Write "</td>" & vbCrLf Next 'I Response.Write "</tr>" & vbCrLf rstExcel.MoveNext Loop %> </table> <% rstExcel.Close Set rstExcel = Nothing cnnExcel.Close Set cnnExcel = Nothing %>
