Answer 1

You can use a Panel, a TextBox and a PictureBox.

The TextBox must be placed in a Panel so you can't write over your search picture.

Answer 2

You can create a new UserControl which will do the required job. You have to extend the TextBox class for that. Look at the code below:

    public class IconTextBox : System.Windows.Forms.TextBox
    {
        public IconTextBox() : base() { SetStyle(System.Windows.Forms.ControlStyles.UserPaint, true); this.Multiline = true; }

        public System.Drawing.Bitmap BitmapImage
        {
            set;
            get;
        }

        protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
        {
            base.OnPaint(e);
            System.Drawing.Image img = BitmapImage as System.Drawing.Image;
            e.Graphics.DrawImage(img, new System.Drawing.Point(this.Width - (img.Width), 0));

        }

    }

And in the OnPaint method you can specify the image. Also you can extend this to have a custom property which can be the image path. Your choice.
