System date validate upon application launch

I have built an applescript based app in Xcode V3.2.6 under OSX 10.6.7. I want to have additional code to my application so when the system launched, it will compare the date I set in the application with the system date. If date within range specified, proceed. If date check is out of range then terminate program immediately.

currently the code looks something like this:

on clicked the Object
    if name of theObject = "One" then
        try
            display dialog "ONE"
        end try

    else开发者_运维知识库 if name of theObject = "two" then
        try
            display dialog "TWO"
        end try
    end if
end clicked

on action theObject

end action

One of the very nice users in this fourm post Chuck has posted something. The code works great under apple scripter but not when I pasted into the Xcode. Can any one tell me what I am doing wrong?

set range to 3 * days 
set targetDate to (date "Saturday, March 19, 2011 12:00:00 AM") 
set currDate to current date 
if abs(targetDate - currDate) > range then 
    display dialog "quit" 
else 
    display dialog "continue" 
end if 

on abs(n) 
    if n < 0 then 
        return -n 
    else 
        return n 
    end if 
end abs 

Thanks so much!

It's been a long time since I worked with the technology formerly known as AppleScript Studio. :) However, I just created a Cocoa-AppleScript application and I see that the file UntitledAppDelegate.applescript has the following by default:

script UntitledAppDelegate
    property parent : class "NSObject"

    on applicationWillFinishLaunching_(aNotification)
        -- Insert code here to initialize your application before any files are opened 
    end applicationWillFinishLaunching_

    on applicationShouldTerminate_(sender)
        -- Insert code here to do any housekeeping before your application quits 
        return current application's NSTerminateNow
    end applicationShouldTerminate_

end script

Note the on applicationWillFinishLaunching_ handler and the comment placed there by Xcode. This is where you want to place code that will execute when the program launches. For example, I placed a beep statement in there and the application beeped when it launched. So I'm guessing you could have something like this:

on applicationWillFinishLaunching_(aNotification)
    -- Insert code here to initialize your application before any files are opened
    set range to 3 * days 
    set targetDate to (date "Saturday, March 19, 2011 12:00:00 AM") 
    set currDate to current date 
    if (currDate - targetDate) > range then 
        display dialog "quit" 
    else 
        display dialog "continue" 
    end if 
end applicationWillFinishLaunching_
