That means: if using CursorLocation-adUseServer, you need a static, keyset or dynamic cursor If using CursorLocation = adUseClient. you will only get a static cursor which supports bookmarks. so, yes, the problem is in your code.

Hi All:
I have just published the same pages to two different web sites (both running Windows 2000 Server). One works perfectly OK, while the other creates the following error: ADODB.Recordset error '800a0cb3' Current Recordset does not support bookmarks. This may be a limitation of the provider or of the selected cursortype. The offending line is: RS.AbsolutePage = intPageNum RS is my current recordset Had both web servers produced the error, I would think that something is wrong with my code, but as mentioned before, only of them creates problems. I can also run the code without problems on my local IIS (a Windows XP Pro machine). Any advice would greatly appreciated. Thanks. TB
It's what happens before that line that's relevant.
Frankly, I would not be using the cursor to provide this functionality. It requires too much overhead in the web server. If you need to implement paging, you should look at the articles on Ken Schaeffer's (www.adopenstatic.com) and Aaron Bertrand's (www.aspfaq.com) sites to see more efficient solutions. However, in order to support bookmarks you need to set the recordset's CursorLocation or CursorType (or both) properties before opening it. The ADO documentation can be found at msdn.microsoft.com/library (you can either drill down through the table of contents to find it, or do a site search for either of the properties I cited above). You should do a thorough reading of the descriptions of these properties to gain an understanding of the ramifications of using each of the non-default settings. My preference would be to use a static cursor, since that is the cheapest cursor that is likely to support bookmarks. Whether or not a server-side or client-side cursor is called for depends on the amount of data that would be retrieved from the database if ALL the records that passed your sql statement's filter were retrieved all at once. The reason the error occurs on one server but not another is proabably attributable to a) different versions of MDAC on each machine b) corrupted ADO files c) different versions of the OLE DB provider you are using By setting the cursor type/location properties explicitly, you will make you app more server-proof.

Thanks for your prompt reply.
The recordset opening line is: RS.Open msql, Conn, 1,3 How should I change that one to make it work on all web servers?

Thanks a lot. I have studied the issue, and have changed the cursor type. In
a future update, I will follow your advice and simply use another form of paging. Thanks again.
