My favorite functions

In a previous message, I wrote about some functions on time. Here are my favorite functions... much better than the previous ones

function GetLastDayPreviousMonth()
Dim dt
Dim firstDay
Dim lastDay
dt = now()
firstDay = DateSerial(Year(dt), Month(dt), 1)
lastday = DateAdd("d",-1,firstDay)
GetLastDayPreviousMonth = lastDay
end function
function GetFirstDayPreviousMonth()
dim firstDay
firstDay = DateSerial(year(GetLastDayPreviousMonth()),month(GetLastDayPreviousMonth()),1)
GetFirstDayPreviousMonth = firstDay
end function

Sillyness.. absolutely :

=dateadd(“d”, –1, dateadd(“m”, -1, cdate(year(today()) & “/” & month(today()) & “/1”)))

will give you the last day of the previous month.

the first day is easier still :

=dateadd(“m”, -1, cdate(year(today()) & “/” & month(today()) & “/1”))

 

 

 

function convertTime(intMinutes)
dim iTimeInHours, iTimeMinutes,strTimeMinutes, strTimeInHours, strTimeInHoursAndMinutes
iTimeInHours = intMinutes \ 60
iTimeMinutes = intMinutes mod 60
if (iTimeInHours < 10) then
strTimeInHours = "0" & cstr(iTimeInHours)
else
strTimeInHours = cstr(iTimeInHours)
end if
if (iTimeMinutes < 10) then
strTimeMinutes = "0" & cstr(iTimeMinutes)
else
strTimeMinutes = cstr(iTimeMinutes)
end if
strTimeInHoursAndMinutes = strTimeInHours & ":" & strTimeMinutes convertTime = strTimeInHoursAndMinutes
end function
function calculateTime(eDt as datetime, sDt as datetime, eLu as Int32)
dim iTime
iTime = DateDiff("n",eDt,sDt) - eLu calculateTime = iTime
end function
