Type Mismatch if not DAO

[Mr.K]

I have a following lines of code:

Dim rs As Recordset

Me.Requery
Set rs = Me.Recordset

However it causes an error "Type Mismatch"

When i change

Dim rs As Recordset

to:

Dim rs As [B]DAO[/B].Recordset

everything works fine. However, I'm not sure why; could somone be so kind as to explain in few sentances the concept of the DAO vs nothing specified?

 

[Mr.K]

Thanks so much; that's exactly the explanation I was hoping for.
