adding the app's start date in message box

[Shiro]

hi,

i have created a very little script which shows a message box.

in the message box i want to add 30 day trial info.

something like this:

Title: You have been using this program since 1 day!

Message: This program 'll expire in 29 days!

how would i do this?

[Yashied]

MsgBox(64, "You have been using this program since 1 day!", "This program 'll expire in 29 days!")

???

MsgBox(64, "You have been using this program since 1 day!", "This program 'll expire in 29 days!")

???

it's not what i am looking for, i know MsgBox() very well.

the problem is that i want it to be changed every day!

Like if i ran/run the app today then it 'll say!

Title: You have been using this program since 1 day!

Message: This program 'll expire in 29 days!

After 5 days:

Title: You have been using this program since 5 days!

Message: This program 'll expire in 25 days!

after 18 days:

Title: You have been using this program since 18 days!

Message: This program 'll expire in 12 days!

i hope you got my point, in the message box i want to add 30 day trial info.

Keep the starting date in the registry, and every time you start program compare this date with the current date.

[Shiro]

any example?

[CodyBarrett]

im not sure about the registry so i wont post it... but

$startup = ;the registry key you need... or anyfile you wanted to write
$0 = @YDAY
msgbox (0,'',$0 - $startup & ' days left on trial.')

just as an example mind you... use more indepth math operations and string manipulations to do it more efficiently... also get the @YEAR and then compare that as well

[Shiro]

well, i could not understand at all, where in msgbox $0 is @day & $startup is the registry key?

if we store some spesific date in a txt fie or in registry key then how it 'll show them as i want them?

i think in the example mentioned above there is nothing which can help me to write it.

i mean something like "you have passed 1 day(s) running this app and 29 day(s) are left."

can any one post a example of storing date in txt file and do as i asked?

This example should make it clearer for you. It uses the registry rather than a text file to store the date the application was first run.

#include <Date.au3>

MsgBox(0 ,"Days Used", "You have been using this application for " &  _GetNumDaysSinceFirstRun() & " days")

Func _GetNumDaysSinceFirstRun()
Local $NumDaysUsed = 0
Local $InstallDate = ""
Local $TodaysDate = _NowCalcDate()
;To test uncomment the line below to test, Adds 9 days to todays date
;$TodaysDate = _DateAdd("D",9,$TodaysDate)

    $InstallDate = RegRead ("HKEY_LOCAL_MACHINE\SOFTWARE\mytrialapplication", "firstrun" )
    If @error Then
        ; Registry key does not exist so it's probably the
        ; first time application has been run so store todays date in registry
        RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\mytrialapplication", "firstrun", "REG_SZ",  $TodaysDate)
        ;Number of days used is 0
        Return $NumDaysUsed
    Else
        ; Calculate the number of days between install date and today
        $NumDaysUsed = _DateDiff("D", $InstallDate, $TodaysDate)
    EndIf
    Return $NumDaysUsed
EndFunc

thanks a lot "Bowmore" but how can i get the information of days left in expiration?

For example it says: You have been using this application for 0 days.

and i also want to show days left: You have been using this application for 0 days and it will expire in 30 days.

[CodyBarrett]

use math

[Shiro]

any example code?

[CodyBarrett]

use this lol

$started = ;when you started the trial... get this date from however means you wish
$current = @yday
$daysleft = $current - $started

;for example
;$started = 10 (JAN 10TH)
;$Current = 11 (JAN 11TH)
;$Daysleft = $Current - $started

;therefore... $Daysleft = 1

simple as that dont bother running this code it wont work...
