' Public Sub readFromFile(ByVal strFileName As String, ByRef ms As MemoryStream) Dim fs As FileStream ' open the file stream fs = New FileStream(strFileName, FileMode.Open) Dim br As New BinaryReader(fs) Dim arrByte As Byte() ms.Position = 0 While br.BaseStream.Position < br.BaseStream.Length arrByte = br.ReadBytes(4096) ' read in 4 k at a time ms.Write(arrByte, 0, arrByte.Length) End While br.Close() End Sub
