Default ADO.NET(Retrieve image from databse)

i want to retrieive the photo of employees stored in table employees
of Northeind database.
I have 4 buttons(First,Next,Previous,Last) and one PictureBox on the
form.
Coding of the Last button is as follows:

Dim bm As BindingManagerBase
     bm = Me.BindingContext(DsEmployees1, "employees")
     bm.Position = bm.Count - 1
     Dim c As Integer = DsEmployees1.Tables("employees").Rows.Count
Dim ctr As Integer = DsEmployees1.Tables(0).Rows.Count - 1

Dim bytEmpPhoto() As Byte =

DsEmployees1.Tables("employees").Rows(ctr)("Photo" )
     Dim stmEmpPhoto As New MemoryStream(bytEmpPhoto)
     PictureBox1.Image = Image.FromStream(stmEmpPhoto)

This coding gives me an error:
'System.ArgumentException' occured.
Error: Invalid Parameter Used.

You have posted in the Feedback Forum. This topic would be more appropriate in one of the programming forums, in this case probably an ADO forum.

Thanks.

There are only two stupid questions: the one you don't ask, and the one you ask more than once ;)
