get data from dataset

[Palmtree]

I want to get the max column value from a table, the following is my code:

Dim dsTemp As DataSet = New DataSet()
            Dim daTemp As OdbcDataAdapter = New OdbcDataAdapter("Select Max(id) as MaxID from teacher", connTeacher)
            daTemp.Fill(dsTemp, "teacher")

How can I get the value of the MaxID?
