[RESOLVED] date difference

Hi guys, I need help about date differences. See we have a link that I want to expire it after 3 months. So if the user goes to that link, it will say it's expired.

I don't know what is the logic behind it to identify the date that saved in the database and compare it to today's date. If today's date is greater than the date in the db 3 months and more, then the link is expired. Or the year is greater than the year in the db, link expired.

what you can do is something like this:

vb Code:

Dim Today as datetime = system.datetime.now
Dim ExpDate as datetime 
ExpDate = Today.addmonths(3)

I just typed this out and did not check syntax... This will make the ExpDate 3 months from now

Then you can check

vb Code:

If ExpDate > datetime.now then
'Expired
else
'Do whatever you need
End If

When user visits the link, call the database, (you'll undoubtedly have the ID), get all the details that you need out. For example, if it's an article, get the title, body, keywords, published date, etc. out.

Convert the published date to a DateTime. Then compare.

Code:

---

If DateTime.Now.AddMonths(3) >= publishedDate Then
Response.StatusCode = 410
Response.Status = "Expired"
LabelMessage.Text = "This article no longer exists."
End If

---

(Something like that, don't copy paste it)
