Pixelbox shows error image on valid bitmap


I have a wired probly. I recieve pixel data from a web control (Awesomium). I want to display the bipmap in a PictureBox.

using (System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(viewPortX, viewPortY, System.Drawing.Imaging.PixelFormat.Format32bppArgb))
  {
    BitmapData bmpData = bmp.LockBits(new Rectangle(0, 0, bmp.Width, bmp.Height), ImageLockMode.WriteOnly, bmp.PixelFormat);
    BitmapSurface bmpSurface = (BitmapSurface)htmlHolder.Surface;
    bmpSurface.CopyTo(bmpData.Scan0, bmpSurface.RowSpan, 4, false, false);
    bmp.UnlockBits(bmpData);

    bmp.Save("result.jpg", ImageFormat.Jpeg);
    pictureBox.Load(result.jpg);
  }

This works fine. The bitmap is diaplayed. If I change 

bmp.Save("result.jpg", ImageFormat.Jpeg);
pictureBox.Load(result.jpg);

to

pictureBox.Image = bmp;

then the eror image is shown in the PictureBox.
Any idea what's is wrong?

because you destroy bmp object before it get's loaded into picturebox. using statement dispose image created within it's range.
