System.GetDate Examples

string System.GetDate (

Example 1

current_date_sortable = System.GetDate(2); -- ISO date format sorts nicely

Get's the current date in ISO format (YYYY-MM-DD) and stores it in the variable "current_date_sortable."

Example 2

days_since_Jan_15_2003 = System.GetDate(3)-2452655; -- 2452655 is the Julian date for Jan 15, 2003

Subtracts the Julian date for Jan 15, 2003 from the current Julian date and stores the result in the variable "days_since_Jan_15_2003". The Julian date format is perfect for date comparisons.

Example 3

nWeekday = System.GetDate(7);

Returns the current day of the week (1-7) in the variable "nWeekday."

Example 4

-- Specify the length of the trial period, in days

time_limit = 30;

-- Initialize days_left

days_left = 0;

-- Retrieve previous value stored

date_installed = Application.LoadValue("My Application", "Date Installed");-- Convert loaded value into a number

date_installed = String.ToNumber(date_installed);

-- If there is no previous value (date_installed == 0), create a value

if date_installed == 0 then

Application.SaveValue("My Application", "Date Installed", System.GetDate(DATE_FMT_JULIAN));

days_left = time_limit;

else

days_left = (date_installed + time_limit) - System.GetDate(DATE_FMT_JULIAN);

end

-- Check if there is time left

if String.ToNumber(days_left) < 1 then

Dialog.Message("Trial Period Over", "This software has expired");

Application.Exit();

else

Dialog.Message("Trial Period", "You have "..days_left.." days left in your trial period.");

end

Notifies the user after thirty days that the installation has expired and exits.
