I've developed a database in Access 2000 on Windows 2000. I have been
asked to put the database on a machine running Windows XP. I copied
the database onto the XP machine with some data already in it.
Everything seemed to be working correctly, until I tried to import new
data.
New data is imported into the database from a floppy disk. To prevent
duplicate entries, I have a boolean function called Exists which uses
the Seek method of Recordset to search for a value already existing in
a table. If the value is in the table, Exists returns True, and False
otherwise.
This function works correctly on my Windows 2000 machine, but on the XP
machine I get the following error message:
Error 3251: Operation is not supported for this type of object
Below is my code for the Exists function with a comment showing where
the error occurs. My references include Microsoft DAO 3.6 Object
Library.
I would greatly appreciate if anyone could tell me why this error is
occurring on the XP machine and how I can correct it. I would even
take suggestions for an alternate way of doing the same thing.

If RS.NoMatch = True Then
Exists = False
Else
Exists = True
End If
RS.Close
End Function

OK, so I thought the problem was a result of the app being developed on
Windows 2000 and then being moved to XP, and there was some version conflict
with somethingorothe r. But I tried this on my XP laptop at home, and it
works fine.
I'm still curious if anyone has any idea about what the problem could be,
but I'm going to use DCount instead of the Recordset methods. I just need
to wait until I'm back in the office to see if DCount gives me any trouble
on the other machine.
Thanks in advance.

DCount() should be fine.
The Seek method (DAO) works only for recordsets of type dbOpenTable.
That type applies only to local tables, not attached tables which open as
dbOpenDynaset by default.

Thank you for the explanation. That makes perfect sense - I split the
application on the XP machine at work, but not on my laptop.

I want the recordset (rs) in the following function to be updateable.
How do I do it?
Even though the code is VBA I will be translating to VBS for a MS SQL

open the Connection and/or Recordset so I can change the SQL WHERE
clause in the loop & then update the resulting recordset.

When you create an ADO Recordset, you should have some idea as to what functionality the Recordset does/does not provide. Some critical questions may, and should, be:
Can I add New Records to the Recordset?
Does the Recordset support Bookmarks?
Can we use the Find and/or Seek Methods with this Recordset?
Does the Recordset support the use of Indexes?
Will the Absoluteposition property be able to be used on this Recordset?
etc....

Hi,
I am having a problem using Dreamweaver CS3 standard recordset paging behavior. It doesn’t seem to work when I pass parameter values from a FORM on my search page, to the recordset on my results page.
- Recordset Paging works if no parameters are used in the recordset sql code (ie. simple sql code):

WHERE (db_field1 LIKE ‘%text1%’ OR db_field2 LIKE ‘%text2%’)
