如何计算出当前日期属于定义时间段内的第几星期？
Function CalculateWeekNo(BeginDate,EndDate,InputDate)
dim wdate(500,8)
z=0
x=0
strlong=len(CStr(inputdate))-9
inputdate=cdate(left(CStr(inputdate),strlong))
for i=cdate(BeginDate) to cdate(EndDate)
if inputdate=i then
x=z
Exit For
end if
if weekday(i)=7 then
z=z+1
end if
next
CalculateWeekNo=x
end Function
