Visual Basic - los dias del mes

does anyone know how I can get the maximum days in a month. e.g.. February = 28 into a variable?

eso me lo pregunto un amigo en ingles, pero basicamente el desea saber cuantos, dias trae el mes, si esta en septiembre sabe que son
30 dias, y si esta en agosto que son 31 dias, algo asi.

Take the actual date, add a month and then substract the same date's day:
25/8/2002 + 1 month = 25/9/2002 - 25 days = 31/8/2002.

I don't remember exactly how it was, but it was something like this:
dt = dateadd(date, "M", 1) '(25/8/2002 + 1 month = 25/9/2002)
dt = dateadd(dt, "d", -(day(dt))) '(25/9/2002 - 25 days = 31/8/2002)
variable = day(dt) '(31)
