Running a Visual Basic application using the Microsoft RDS Data Factory to access Index Server 2.0 can generate the following errors:

This happens when Running Index Server 2.0 on Windows NT 4.0 with service pack 3.0 (or an older service pack).

To resolve this run Index Server 2.0 with Windows NT 4.0 Service Pack 4 (or beyond).

Index Server 2.0 was shipped (with Windows NT Option Pack 4) before the MDAC 2.0 release. As a result, Index Server 2.0 was not tested with MDAC 2.0 components when it was released. The release of Service Pack 4 for Windows NT 4.0 included some modifications that corrected the way Index Server 2.0 works with RDS 2.0 components (or later versions).

Steps to Reproduce Behavior

1. Start a new Microsoft Visual Basic project. Form1 is created by default.
2. Reference the following libraries from the Project/Reference menu:
   • "Microsoft ActiveX Data Objects 2.0 (or 2.1) library"
   • "Microsoft Remote Data Services 2.0 (or 2.1) library"
3. Insert a Command Button on the form. Command1 is created by default.
4. Insert the following code into the General Declaration section of Form1:

   Option Explicit
   Dim RS As ADODB.Recordset
   
   Private Sub DoQuery(HTTPServer As String)
   
       Dim Scope, QueryText, sSQL As String
   
       Scope = "C:\"                   ' Set the scope of the query
       QueryText = "Index"      ' Set the criteria of the query
       
       sSQL = "SELECT Filename, Path, Size, Write FROM Scope('" + Chr(34) + _
            Scope + Chr(34) + "') WHERE CONTAINS('" + Chr(34) + QueryText + _
            Chr(34) + "') > 0" ' ORDER BY Rank DESC"
   
       ' Create the recordset via the data-factory
       Data_Factory HTTPServer, sSQL
   
       ' Print out column titles
       Debug.Print "Filename", "Path", "Size", "Write"
       Debug.Print "-------------", "------", "------", "----------"
       ' Print out data
       
      Do Until RS.EOF
           Debug.Print RS("Filename"), RS("Path"), RS("Size"), RS("Write")
           RS.MoveNext
       Loop
       
       RS.Close
       Set RS = Nothing
       
   End Sub
   
   Private Sub Command1_Click()
       Dim HTTPServer As String
       Dim WebServer As String
       
       WebServer = InputBox("What is the name of your Web (IIS) Server?")
       HTTPServer = WebServer
       
       ' Execute the query
       DoQuery (HTTPServer)
       
   End Sub
   
   Public Sub Data_Factory(HTTPServer As String, sSQL As String)
       
       Dim DS As New RDS.DataSpace
       Dim DF As Object
       
       Set DF = DS.CreateObject("RDSServer.DataFactory", "http:/" & HTTPServer)
       'next line produces error (not recognizing the provider) with NT4 SP3 or before
       Set RS = DF.Query("Provider=msidxs", sSQL, adOpenDynamic)
      
   End Sub
       
   
   					

5. Press F5 to run your project. Specify the name of your web server when prompted to do so.
