  2. {  
  3.     PictureBox imageControl = newPictureBox();  
  4.     imageControl.Width = 400;  
  5.     imageControl.Height = 400;  
  6.     Bitmap image = newBitmap("C:\\Images\\Creek.jpg");  
  7.     imageControl.Dock = DockStyle.Fill;  
  8.     imageControl.Image = (Image) image;  
  9.     Controls.Add(imageControl);  
  10. }
