@year @Mon @Mday

Hello I have a little big problem.

I made a program that recovers data by ftp from today and back for 2 days;

in practice retrieves the file with date of today, yesterday and the day before yesterday.

So to do this' I used a simple procedure to subtract the days of the date hereof:

$ year = @ YEAR

$ month = @ MON

$ day = @ MDAY

$ date = $ year & $ month & $ day

data_1 $ = $ year & $ month & ($ day - 1)

data_2 $ = $ year & $ month & ($ day - 2)

The procedure has worked for 10-15 days. At any moment when I launch the program (the executable program mean that I have created 15 days ago) the program gives me the variable and the variable $ $ data_1 data_2 are equal to zero, if I debug it tells me that have results for "false".

Because they are ignorant and I was very happy to have done little program and it worked, I explain now you know why 'should not be more'.

Premise that the executable file 'was compiled in both 32-bit and 64 bit (xp and 7) and is used on 4 different pc, and all by the fact that I do not get more' files for the two variables question.

I do not remember if it worked the last time we were still in July. (you know who does not have any control over how many days a month, but since I use it only when I know I can use it )

Aiutooooo!!

Thanks

Your script wont' work at the start of a month and return an invalid date. Let's say 2012-08-01 would result in 2012-08-00 or even 2012-08--1

Use function _DateAdd to add or subtract dates.

The following example takes the current data and subtracts 1 resp. 2 and assigns it to variables:

#include <date.au3>
$date1 = _DateAdd("d", -1, _NowCalcDate())
$date2 = _DateAdd("d", -2, _NowCalcDate())
ConsoleWrite($date1 & @LF)
ConsoleWrite($date2 & @LF)

Properly written (you have spaces where none should be and $s that are out of place) the code you gave works fine. I just added the StringFormat() to set @MDAY to 2 digits.

$year = @YEAR
$month = @MON
$day = @MDAY
$date = $year & $month & $day
$data_1 = $year & $month & StringFormat("%02d",$day - 1)
$data_2 = $year & $month & StringFormat("%02d",$day - 2)
ConsoleWrite("Date: " & $date & @CRLF & "Data_1: " & $data_1 & @CRLF & "Data_2: " & $data_2 & @CRLF)

This however is shorter and does the same thing.

$date = @YEAR & @MON & StringFormat("%02d",@MDAY)
$data_1 = @YEAR & @MON & StringFormat("%02d",@MDAY - 1)
$data_2 = @YEAR & @MON & StringFormat("%02d",@MDAY - 2)
ConsoleWrite("Date: " & $date & @CRLF & "Data_1: " & $data_1 & @CRLF & "Data_2: " & $data_2 & @CRLF)

All that being said; Water is correct in what function to use.
