.net date functions

[athar258]

hi all,
i am writing a program for an institute where students pay their fees monthly on different dates for the courses they're registered. for example, if i pay the first fee on 24th of february, my next fee dues on 24th of march, and if you pay your first fee on 05th of december, your next fee dues on 05th of january.
the issue is i need to figure out when the fee is due for a student. my brain is completely choked on this. .net provides a function by which i could figure out the number of days through a time span between two dates, i.e.

dim timeSpan1, timeSpan2 as timeSpan
dim resultTimeSpan as timeSpan

resultTimeSpan = timeSpan2.subtract(timeSpan1)

dim noOfDays as integer = resultTimeSpan.days

the above code is ok to figure out number of days, but i need to have a chunk of code that will tell me whether a month is passed by since the last payment, and if it has, i will flag the student as defaulter.
for some of you, the problem may sound a piece of cake, dont call me a stupid cuz as i said for some reasons my brain is totally choked on that..

a bigg bigg thank in advance for the helper.

.NET provides handy stuff like DateTime.Day, DateTime.Month and DateTime.Year. There is also a method called DateTime.AddMonths(int months). Check it out :-)

thanks steven for your consideration..i thought its gonna take a day or two for the reply..but it was really quick..

about the problem..may be i failed to explain the problem clearly..
see for instance.. suppose you pay your fee on 10th of every month, the last payment you made was on 10th of july.
while running the procedure today (on 11th of august) for determining all the student who have not paid the fee, i will go into the database, get your last payment date (i.e. 10th july) and compare the date with todays.there should be a decent way to find out that as of 11th of august, a month has passed by and you need to make a payment for the next month..

may be thats clear enough.. because dateTime.month only gives me the month of the given date, so do the dateTime.year and dateTime.year functions.

thanks

No problem. Care to post the code you used to solve this (mind the Code-tags!)
