Scripts > Schedule Task in ASP

Scheduled Task in Active Server Pages

This useful re-usable function enables you to effectively schedule a task in an ASP application. The scheduled task is in the form of any ASP function.

NB: The scheduled function actually runs the first time after the specified time period that a visitor browses to the ASP page. If the Application is restarted, the specified function is also executed immediately.

Using the Schedule Task function

The function definition looks like this: ScheduleTask(task_name, period, qty)

It returns a boolean result of True if the scheduled task is due to be run immediately, otherwise returns False.

task_name
A unique string for the name for your task, e.g, "MyTask1". The timestamp of the last time the task was run is stored in an application variable based on this name.

period
The period parameter specified must be one of the Date constants

qty
The number of intervals between tasks, with the interval as specified by the value of the period parameter.

Schedule Task Example Code

In the code below, the function AnyFunction will run every 6 hours. The timestamp of the last time this task was run, will be stored in an application variable called Sched_MyTaskName

'call AnyFunction() once every 6 hrs
If (ScheduleTask("MyTaskName", "h", 6)) Then
  Call AnyFunction()
end If

FUNCTION ScheduleTask(task_name, period, qty)
  Dim RunNow
  Dim last_date
  Dim diff

  'boolean result
  RunNow = False

  'chcek the value of app setting
  last_date = Trim(Application("Sched_" & task_name))

  'is value empty? maybe app just started
  If (last_date = "") Then
    RunNow = True
  Else
    'is value old?
    diff = DateDiff(period, last_date, Now())
    If (diff>=qty) Then RunNow = True
  End if

  'if scheduled to run now, set the app last run time
  If (RunNow) Then Application("Sched_" & task_name) = Now()

  'return result
  ScheduleTask = RunNow
END FUNCTION

FUNCTION AnyFunction()
'your code here
END FUNCTION
