calendar compare date.

[Madeleine]

i want to check if the date selected is before the today date. if yes, i wish to return a message in the label.

if (Convert.ToDateTime(Calendar1.SelectedDate.Date) = (Convert.ToDateTime(Calendar1.SelectedDate.Date)))
{
Label1.Text += "Select date after or today date";
}






another prob is my datediff don't seem to work. anyway MPAnnouncement.date_posted is a column name in my annoncement table.

SELECT MPAnnouncement.announcement, MPAnnouncement.date_posted, MPAnnouncement.subject, MPUser.user_name FROM MPAnnouncement INNER JOIN MPUser ON MPAnnouncement.user_id = MPUser.user_id WHERE (MPAnnouncement.display_to = 'Industry') OR(MPAnnouncement.display_to = 'All') OR (MPAnnouncement.display_to LIKE '%I%') AND (DATEDIFF (d,MPAnnouncement.date_posted,GETDATE())=0)



thanks
