The example is called CustQueP, from Mastering delphi 6, chapter 22, page 970. Made it a CGI-app. Works perfect. Now I try to let it work with Interbase 6.0.1.6. The pageProducer refuse to fill the comboboxes. I tried with BDE (TDatabase) and dbExpress; both give the same problem. I use delphi 6 Pro, WinXP Pro, IIS 5.1. Thanks for your help. Alfred.

However show us please a piece of your code to see what's going on.

The HTML for the Pageproducer is here: <h4>Customer QueryProducer Search Form</h4> <form action="<#script>/search" method="POST"> <table> <tr><td>State:</td><td><select name="State"> <#State> </select> </td></tr> <tr><td>Country:</td><td><select name="Country"> <option> </option> <#Country> </select> </td></tr> <tr><td></td><td><center><input type="Submit"></center></td></tr> </table></form> And here is the Pageproducer's OnHTMLTag-event: procedure TWebModule1.PageProducer1HTMLTag(Sender: TObject; Tag: TTag; const TagString: String; TagParams: TStrings; var ReplaceText: String); begin if TagString = 'script' then ReplaceText := Request.InternalScriptName else begin ReplaceText := ''; Query2.SQL.Clear; Query2.SQL.Add ('select distinct ' + TagString + ' from customer'); try Query2.Open; try Query2.First; while not Query2.EOF do begin ReplaceText := ReplaceText + '<option>' + Query2.Fields[0].AsString + '</option>'#13; Query2.Next; end; finally Query2.Close; end; except ReplaceText := '{wrong field: ' + TagString + '}'; end; end; end; If I link the Query to DBDemos, all works fine. If I link the Query, via a TDatabase, to Mastsql.gdb in the "Borland SharedData" directory it don't. I get the form, but the comboboxes are not filled with data. The same when I use dbExpress to get the info out of Mastsql.gdb. Even if I don't use a Pageproducer, but write all HTML in code, same result. So what is going wrong? I don't grasp it. TIA, Alfred.

Quote: I presume you have an active Transaction in your IB? Chris Sure. BTW if I don't use the PageProducer and put all the (HTML)code in an ActionHandler (still using the IB-query), the effect is the same. If I write the Response.Content-string to a file (say Test.htm) and open the file in IE the form is OK. Alfred.

Can't think why you couldn't get your SQL Query data unless your SQL statement is not qualified correctly?

Chris Thanks Chris, I had the database and IB-Server on the same disk as IIS, so I thought that a local path (without ComputerName) was sufficient. Now I learned that the connectionstring must contain the servername as well. Problem solved. Alfred.
