Saving Image into memory stream Error - vb.net

Question

I'm trying to:
1) Scan an image and insert it to a memorystream.
2) Show it in picturebox1.
3) Read picturebox1 image into memorystream and save it to oledb.
here's my code :
1st) Scanning by WIA Dialog and inserting image to memorystream then showing it in picturebox1:
Try
Dim CD As New WIA.CommonDialog
Dim F As WIA.ImageFile = CD.ShowAcquireImage(WIA.WiaDeviceType.ScannerDeviceType)
If F IsNot Nothing Then
Dim MStream As IO.MemoryStream = Nothing
Try
'Convert the raw scanner output into a byte array
Dim ImageBytes() As Byte = DirectCast(F.FileData.BinaryData, Byte())
'Read the image data bytes into a MemoryStream
MStream = New IO.MemoryStream(ImageBytes)
PictureBox1.Image = System.Drawing.Image.FromStream(MStream)
Catch ex As Exception
MsgBox("An error occurred: " & ex.Message, MsgBoxStyle.Critical)
End Try
If MStream IsNot Nothing Then MStream.Dispose()
End If
Catch ex As Exception
MsgBox(ex.message, MsgBoxStyle.Critical)
End Try
This is working perfectly.
The problem is coming,
2nd) Reading image from picturebox1 into new memorystream then save it to oledb:
If conn.State = ConnectionState.Closed Then
conn.ConnectionString = connstring
conn.Open()
'Reading image from picturebox1 and then insert it to a new memorystream.
Dim arrImage() As Byte
Dim myMs As New IO.MemoryStream
PictureBox1.Image.Save(myMs, System.Drawing.Imaging.ImageFormat.Jpeg)
arrImage = myMs.GetBuffer
'Now save image to oledb from the memorystream.
Dim query As String = "INSERT INTO Guestinfo ([IDImage]) VALUES (#IDImage)"
Dim command As New OleDbCommand
With command
.CommandText = query
.Parameters.Add("#IDImage", OleDb.OleDbType.Binary).Value = arrImage
.Connection = conn
.ExecuteNonQuery()
End With
MsgBox("Saved Successfully!", MsgBoxStyle.Information)
conn.Close()
ListView1.Items.Clear()
loadlistview()
Me.Close()
End If
Error is on this line :
PictureBox1.Image.Save(myMs, System.Drawing.Imaging.ImageFormat.Jpeg)
I might see that this error because during the scanning process we were converting the image into byte array to put it into memorystream, but while reading process we were trying to read the picturebox image as Jpeg into memorystream.
I can see it's complicated for me as a beginner in visualbasic any help would be appreciated.

Per the documentation for Image.FromStream, the stream must be kept open for the lifetime of the Image, but you are disposing of the stream in this line:
If MStream IsNot Nothing Then MStream.Dispose()
Try removing that line from your first code block.
I suppose the MemoryStream should be disposed of at some point, but perhaps the PictureBox and Image classes will take care of that for you. Otherwise, you may have to add a Dispose call when the form is closed.
