Default bindings & images

Hello,

How must I do to bind a picture with a picture box?

When I tried it, I get an invalid typecast exception.

Binding ImageBinding;
ImageBinding = new Binding("Image", dsRadiografias, "RADIOGRAFIAS.rad_imagen");
//ImageBinding.Format += new ConvertEventHandler(this.PictureFormat);
picRadiografia.DataBindings.Add(ImageBinding);

I was trying with this conversion routine, with no good results:

void PictureFormat(Object sender, ConvertEventArgs e)
{
   try
   {
      Byte[] img = (Byte[]) e.Value;
      // Perform the conversion
      MemoryStream ms = new MemoryStream();
      int offset = 0; // should be 0
      ms.Write(img, offset, img.Length - offset);
      Bitmap bmp = new Bitmap(ms);
      ms.Close();

      // Writes the new value back
      e.Value = bmp;
   }
   catch(Exception)
   {
   }
}

Sorry, there is no problem. I was fighting with another error, but I got confused for the null values when I tried to insert new records.
