Converting byte data values in to an Bitmap Image

I need To Read a Image file which is Binary File in to a Byte and then Convert that byte data values in to an Bitmap Image.

Here is my code i get error "File Not Found "when i will call it in my button click

as:- bitmap_image()

---------------------------------------

my function is here to create bitmap image.

Public Sub bitmap_image() '(ByVal sender As Object, ByVal e As System.EventArgs) '(ByVal open_file_name As String)


Dim total_byte As Long
Dim l As Long = 0
Dim n As Integer = 0

Dim image_file As FileStream = New FileStream(open_file_name, FileMode.Open, FileAccess.Read)

total_byte = New System.IO.FileInfo(open_file_name).Length

Dim ms As MemoryStream = New MemoryStream()

Dim i As Integer = 0


image_file.Seek(0, SeekOrigin.Begin)
'Seek(strat)
For i = 0 To total_byte
n = image_file.ReadByte()
ms.WriteByte(n)
's = s + Convert.ToChar(n)

Next
'Return s
Dim bit_map As New Bitmap(ms)
pic.Image = bit_map
image_file.Close()

End Sub

----------------------------------------

Any thing wrong???
