SiComponents Scheduling Agent is a VCL wrapper for Microsoft Task Scheduler API. The core component TTaskScheduler and attendant classes enable your Delphi or C++ Builder application to:

Enumerate all tasks on a target computer.
Create new scheduled tasks and delete existing ones.
Schedule a task to run at a specific time or when a specific event occurs.
Change the schedule for a task.
Modify other settings for a task, for example, application name, parameter string, working directory, etc.
Run immediately or stop a scheduled task.
TTaskPropertiesDialog allows the standard properties dialog for a task item to be displayed. The component provides the number of properties which help to customize the dialog behavior and appearance.
