Dim con As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\arima\Documents\Consumer & rooms Database.mdb")

You also need an OleDbCommand associated with the connection. The OleDbCommand.CommandText property is where your SQL statements go. Then you can .Open() the connection, so the command object can execute the SQL statements.
Here's the general idea:
Using con As New OleDbConnection("connection string here"), _
cmd As New OleDbCommand("SELECT * FROM MyTable WHERE MyColumn = ?", con)
cmd.Parameters.Add("?", OleDbType.VarWChar, 25).Value = "SomeValue"
con.Open()
Using rdr As OleDbDataReader = cmd.ExecuteReader()
While rdr.Read()
' Do something with each record
End While
End Using
End Using
Alternatively, you can use an OleDbDataAdapter to fill a DataTable or DataSet:
Dim dt As New DataTable
Using con As New OleDbConnection("connection string here"), _
da As New OleDbDataAdapter("SELECT * FROM MyTable WHERE MyColumn = ?", con)
da.SelectCommand.Parameters.Add("?", OleDbType.VarWChar, 25).Value = "SomeValue"
da.Fill(dt)
End Using
