When i try to display an image i get the error:
"Invalid Parameter Used"
This happens at code section:

Dim im As Bitmap = New Bitmap(mem)

Below is the entire code


Try
   Connect()
   jesacmd = New SqlCommand("SELECT PER_SIGN FROM PER_INFO_SIGN WHERE
   PER_NAME = '" & CheqOwnerComboBox.SelectedItem.ToString & "'",
   jesacon)

   jesacon.Open()
   Dim imagedata() As Byte = CType(jesacmd.ExecuteScalar(), Byte())

   Dim mem As MemoryStream = New MemoryStream(imagedata)
   Dim im As Bitmap = New Bitmap(mem)
   DisplaySignPictureBox.Image = im

Catch ex As Exception
   MsgBox(ex.Message)
End Try
   jesacon.Close()

Thanks
