get picture from access db

[bommelding]

I am trying to retrieve a picture that is stored in an access db with the following code:

 

 MyConnection.Open()
       Dim MyCommand As New OleDbCommand("SELECT * FROM tblwater WHERE waterid=" & wateren.waterid, MyConnection)
       MyReader = MyCommand.ExecuteReader()
       MyReader.Read()
       txtnaam.Text = MyReader("water_naam")
       txtplaats.Text = MyReader("water_plaats")
       txttype.Text = MyReader("water_soort")
       txtomschrijving.Text = MyReader("water_omschrijving")
       txtopp.Text = MyReader("water_opp")
       'foto ophalen

       Dim bytBLOBData(MyReader.GetBytes(1, 7, Nothing, 0, Integer.MaxValue) - 1) As Byte
       MyReader.GetBytes(1, 0, bytBLOBData, 0, bytBLOBData.Length)
       Dim stmBLOBData As New MemoryStream(bytBLOBData)
       waterfoto.Image = Image.FromStream(stmBLOBData)
       
       MyConnection.Close()

 

At myreader.getbytes I get an error, does anyone know what I should do to make it work?
