How do you think AutoIt can calculate a valid result when DD is 2 and you want to go 8 days back?

Terenz,

You said earlier you had "Day/Month/Year". :wacko:

How about explaining what you are actually trying to do. :)

I have found the solution by myself, thanks to Melba and "Date" UDF

#include <Date.au3>

Local $D, $M, $Y, $8DaysAgo = 8

Local $sNowDate_ToDays = _DateToDayValue(@YEAR, @MON, @MDAY)
$sDate = _DayValueToDate($sNowDate_ToDays - $8DaysAgo, $Y, $M, $D)
MsgBox(0, 0, "8 days ago was: " & $D & "/" & $M & "/" & $Y)

You're making your life more complex than it should be:

#include <Date.au3>
ConsoleWrite(StringRegExpReplace(_DateAdd("D", -8, _NowCalcDate()), "(\d+)/(\d+)/(\d+)", "$3/$2/$1") & @LF)

The example code in the Help file deserves some thanks too. I am stumped as to why that function accepts either 3 or 4 parameters. I know I could figure this out myself by looking thru the Date.au3 UDF, but it concerns me not and I need 10 more cups of coffee. </slight hijack>

_DateAdd only accepts 3 parameters.

_NowCalc doesn't accept a parameter.

_DateToDayValue only accepts 3.

...

Which function are you talking about? :huh:

somdcomputerguy,

You do realise that there are 2 complementary functions in that snippet? :huh:

_DateToDayValue - which takes 3 parameters - ($iYear, $iMonth, $iDay)

and

_DayValueToDate - which takes 4 - ($iJulianDate, $iYear, $iMonth, $iDay)

The reasons for the extra parameter in the latter seem pretty obvious. ;)

:oops:

Make that a dozen cups.. I'm so glad that I have an optometrist appointment tomorrow, which according to modified sample code in the Help file is

#include <Date.au3>

Local $sNewDate = _DateAdd('d', 1, _NowCalcDate())
MsgBox(4096, "", "Tomorrow is:" & $sNewDate)

I am not sarcasm's lover. Nowhere, in the _DateAdd example, it says that you can subtract a value, rather:

$iValToAdd = number to be added

And the function is calle DateAdd and not DateSub

I'll set the jchd "mark solved" when he change 8 with -8. Thanks

The examples show exactly that:

; Subtract 2 weeks from today
$sNewDate = _DateAdd('w', -2, _NowCalcDate())
MsgBox(4096, "", "Today minus 2 weeks: " & $sNewDate)

Adding a negative number is effectively a subtraction.

Terenz,

Really? :huh:

The second snippet in the example code reads:

; Subtract 2 weeks from today
$sNewDate = _DateAdd('w', -2, _NowCalcDate())
which seems pretty clear to me. ;)

However, I have now amended the text of the Help file page to make it quite clear in future that you can both add and subtract using this function. :)

I dont' have see the "Example" ( my bad ) i have read the _DateAdd ( $sType, $iValToAdd, $sDate ) and the parameters $iValToAdd = number to be added

On MSDN is more clear:

Number ( $iValToAdd <> $iNumber )

Floating-point expression representing the number of intervals you want to add. Number can be positive (to get date/time values in the future) or negative (to get date/time values in the past) etc...

EDIT: Set jchd like "mark solved"
