xHTML | Align center table

After hours of searching and checking, the following code makes your table
to align center of the screen.
This code tested and working on some WAP xHTML (MP) devices.

The first code should set table's margin as the following:
table
{
  margin-left: auto;
  margin-right: auto;
}

now, insert your table in div element:
<div style="text-align: center;">
  <table>
  ...
  </table>
</div>

Enjoy.

Asp.Net - check/validate cookies support

Here is a code for checking/validating that user device (browser) supports cookies. in other words this code checks if cookies are enabled on the browser.

Here the code implemented in the Login page:

    // Constants:
    protected const string QUERYSTRING_CHECK_COOKIE = "checkcookie";
    protected const string TEST_COOKIE_NAME = "check_cookie";
    protected const string TEST_COOKIE_VALUE = "ok";

    // On-load event, at page load:
    protected override void OnLoad(EventArgs p_eventArgs)
    {
        if (IsPostBack == false)
        {
            // Check if browser support cookies
            if (Request[QUERYSTRING_CHECK_COOKIE] == null)
            {
                // try to insert cookie:
                Response.Cookies.Add(new HttpCookie(TEST_COOKIE_NAME, TEST_COOKIE_VALUE));
                string newUrl = string.Format("Login.aspx?{1}=1", QUERYSTRING_CHECK_COOKIE);
                this.Redirect(newUrl, true);
                return;
            }
            else
            {
                // here, client sould contain test cookie:
                HttpCookie cookie = Request.Cookies[TEST_COOKIE_NAME];
                bool isCookieEnabled = cookie != null && cookie.Value == TEST_COOKIE_VALUE;
                if (isCookieEnabled == false)
                {
                    // cookies are disabled!!! show error message
                    Label1.Text = "Device NOT support Cookies!";
                    return;
                }
            }

        }
    }

You can implement this also in other pages than Login page.
