How can we populate a combo box with data from database in 3 tier application in vb.net? please help....

Question

I used this in my client server application. However we now have to convert it to 3 tier application. Can someone please help me. I need to populate the combo box from the data layer.


Private Sub loadStudents()
Dim DBConnection As  New MySQLConn
DBConnection.connect()

Dim Query As String
Query= "SELECT StudentID FROM StudentTable"
Dim dreader As OleDbDataReader

dreader = DBConnection.selectQuery(query)
If dreader.HasRows Then
While dreader.Read
cmbStudID.Items.Add(dreader.Item(0))
End While
End If

End Sub


thanks...
