Здравствуйте, Аноним, Вы писали:

А>Всем доброго времени суток,

А>Подскажите пожалуйста какой-то компонент для ASP.NET 1.1, который позволяет генерировать кртинку с цифрами.
А>Для защиты от спам, ботов и т. д.

А>А также может кто-то знает компонентик, который генерирует картинку с email адресом для тех же целей?

А>Заранее блягодарен,
А>Дмитрий.

Привет!

Это не мое.
где-то взял, мелочь какую-ту менял.
Спасибо забытому мной автору!

Использую так

using System.Web.UI.HtmlControls;

public partial class AntiRobotImagePage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        //if (Session["AntiRobotImageKeyword"] == null)
        //{
            Random random = new Random(unchecked((int)DateTime.Now.Ticks));

            Session["AntiRobotImageKeyword"] = random.Next(100000, 999999).ToString();
        //}
        AntiRobotImage ari = new AntiRobotImage(Session["AntiRobotImageKeyword"].ToString(), 150, 50);

        Response.Clear();
        Response.ContentType = "image/jpeg";
        ari.Image.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);

}

Дальше все понятно, надеюсь.
