Hi,

I want to write a program which will run every day, but show some information to user after 5 days. I am planning to do this by saving in the registry as a date. But can any one tell me the API which will help me getting the date after 5 day from current day???

I mean I want a api which will give the date 6/01/00 if today date is 1/01/00 ( dd/mm/yy)?

Thanks

You need an api to add 5 days to today's date? I'm confused.

What difference would it make? I would say, any time. I basically answered, please see.

What's the difference? No need to complicate things.

Please see:

As you can see, you have two logically equivalent time data structures, with conversion between them:

Now, pay attention that the FILETIME time is measured in 100ns intervals. That said, you need to convert any time you have to this structure and add required value to is. Apparently, one day will be equal to 24 * 60 * 60 * 1000000000/100. If you need, you can then convert this structure to SYSTEMTIME.
