[Dev-C++] OT: week number

[Zodiaq <zo...@ac...>]

Hello Dev-cpp-users,

  yeah, I know this is an off topic question - it is not directly
related to development od Dev-C++ but I also know that this mailing
list reads quite few people so - do you know a good way to check if
two dates are inside one week... dates are in SYSTEMTIME or FILETIME
format... my present idea is not as good as I wish it to be - I start
from first date and try to get to the second one - if I pass sutarday
and still not in second I know that weeks are different... but this
forces some comparisons... know I think that I might check in which
week of the year both dates are - but how to do that? So - if you have
any brilliant ideas share them with me!
