Grace Period past expire date

[VB_Starter]

need help creating code for grace period. I have licenses that expire the last day of the month in a specified year(yyyy), and trying to start code on how to extend the grace period of 30 days past the due date (last day of ea. month) that they come due.
truly,
FRAZZED

If Now > DateAdd("m", 1, ExpireDate) Then

End If

TY for the help, much appreciated

If grace period = 30 days, do i declare that as
DIM GracePeriod As Date

GracePeriod=30 days //this is where i need help

How would I write the If statement?

If I read your original post correctly, you want it for 30 days past the expire date, which is at the end of the month. 30 days is roughly 1 month, so why not give then until the end of the next month? What this code does it runs the code if the date is any date past 1 month past the expire date.

Now, if you really and truly want to give them 30 days past the end of the month (which would not give them until the end of the next month,) Change this bit of code:

DateAdd("m", 1, ExpireDate)

to

DateAdd("d", 30, ExpireDate)

If you want to have a variable placeholder, then declare it as a constant at the top of the form/module, and use that instead.

PUBLIC CONST GRACEDAYS = 30

The explanation helps alot. I will use the code:

DateAdd("m",1,ExpireDate)

Its simpler. Im getting it...thanks alot for your help.

Don't use Now() because the user can just set the date back on their computer. There was a good thread a few weeks ago on something along those lines. Some suggestions where storing it in the registery, getting from the web, etc.

I don't remenber how it ended but it had some good tips.

Good point. And, thinking back, I remember doing just that when I was a kid.

Okay, So I reworked that block a bit with some pseudo-code.

If Now > DateAdd("m", 1, ExpireDate) Then
    Add key to registry that will lock the program until something unlocks it. 
End If

And:

key = Getregistrykey

if key = locking value then
    Give message to user describing locked situation and what he/she
    can do about it.

    Only allow access to main, options, and about forms.

     exit sub
end if

Well I tried a few things, Im unable to store in the registry and get from the web. If expire date is end of the month, they cant renew. I want to allow the license renewal within the 30 days. Once they are pass the 30 day grace period, they cannot renew license. I have If now > dateadd("d", 30, Expiredate) Then they cant renew. Can I take the expire date, add (30 days) and then say they cant renew. More help

Here is a link to a thread from a few years ago that contains a module that will allow you to read/write from/to the registry. Be sure to comment where/who you got it from.

Once you have the registry handling worked out, then you can take your approach and deny the renewals.
