How to select pictures from a database and show in a picture box?
i tried linq to entity worked well for all types of records but problem is to how to select images from a database table?
i tried

using (dbe =new DatabaseEntities())
      {
          var images = from p in dbe.PitureTables
                       select p.Picture;
          foreach (var image in images)
          {
              MessageBox.Show("foreach Run");
              pictureBox2.Image = Image.FromStream(new MemoryStream(image.ToArray()));
          }
      }
there is no any error but the foreach loop wont run, before this block of code i have inserted an image as following
using (dbe = new DatabaseEntities())
           {
              PitureTable record= new PitureTable {PictureName="pic1",Picture=imageToByteArray( pictureBox1.Image)};
                    dbe.StudentRecords.AddObject(record);
                    db.StudentRecords.Attach(record);
                    dbe.SaveChanges();
                    MessageBox.Show("inserted");
                }

Usually I answer most of questions in more or less fine detail, so I'm sorry that I don't do it in this case. The reason is: this question is way, way too popular, and CodeProject keeps many answers to it, answered again and again. Please, just look here:
http://www.codeproject.com/search.aspx?doctypeid=4%3b5&q=database+%28image+OR+picture%29+%28store+OR+get+OR+retrieve%29+PictureBox[^].

You can find more if you remove PictureBox from the query, because it's pretty much irrelevant.

Good luck,
