Ah, sorry, I didnt notice that you were using binary access. Thanks VolteFace.
Dim reader As New IO.BinaryReader(New IO.FileStream("Path to the file", IO.FileMode.Open))
'new binary reader, you have to create a filestream as the BinaryReader
'itself doesnt take file paths but streams
'then you can read
reader.ReadChar() 'or other methods like that
reader.Close() 'close the stream
