编程遇到点问题，求大神指教！！

Private Function checkuser() As Boolean

Dim rs As ADODB.Recordset

Set rs = New ADODB.Recordset

rs.cursortype = adopenkeyset

rs.locktype = adLockOptimistic

sqlconnection = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.Path & "\yyjxc.mdb"

rs.Open "Select * from [user] where name = '" & Trim(suser) & "'and password='" & Trim(spassword) & "'", sqlconnection

If rs.RecordCount = 1 Then

checkuser = True

Else

checkuser = False

End If

End Function

上面代码运行后，无论正确与否，rs.RecordCount 的返回值总不是1，求好心人指教！
