Brain dissolve - record count [Resolved]

How do I find out the recordcount of a table? I don't know if my brain's dissolving or a problem with Access (help files are disappearing, so maybe...)
I had

VB Code:

dim db as database
dim rs as recordset
set db = currentdb
'error on next line - type mismatch
set rs = db.openrecordset("select * from tablename")
if rs.recordcount > 0 then
....
else
....
end if

I swear this works in at least Access 97, but not in 2000. I know this is simple but I'm blanking out on it. Thanks.

Try this :-

set rs = db.openrecordset("tablename")
rs.MoveLast
if rs.recordcount > 0 then

Sometimes I find problems passing arguments requiring string concatenation to a function. It seems safer to use a string variable. eg.
set rs = db.openrecordset(MyString)

I'm wondering if the problem is with Access 2000 being corrupted. The entire function is below. I keep getting a type mismatch at the Set rs = db.OpenRecordset(...) line. I've substituted strSQL, the actual table name, mstrLogName (the table name in a variable) in the argument, no luck. A watch on CurrentDb and db right before that line shows correct types, but no values. This is a form in a database called Test. This is really confusing.
Thanks for any help.

[edit]
Resolved. There were references to both dao and ado. I'd checked references, but to make sure they were there, not that they weren't. Declaring rs as dao.recordset fixed the problem.

VB Code:

Private Function FindExistingRecords() As Boolean
Dim db As Database
Dim rs As Recordset
Dim strSql As String
 
FindExistingRecords = False
strSql = "SELECT * FROM " & mstrLogName '& ";"
 
Set db = CurrentDb
Set rs = db.OpenRecordset(mstrLogName)
rs.MoveLast
 
If rs.RecordCount > 0 Then
    FindExistingRecords = True
    MsgBox (rs.Fields.Count)
End If
End Function
