A trigger is used to run a task automatically based on a schedule, a key press combination, or an event or condition. You can set triggers for a task when you first create it, or you can add them later through the task properties dialog box.
You can also enable and disable triggers from the Task Administrator window. This affects triggering system-wide. If you want to disable triggering for a specific task, either disable the task (see General Task Properties) or remove the trigger (see below).
From the Task Administrator window, open the Managed Task Properties dialog box by selecting the task and clicking Properties or right-click the task and select Properties from the right-click menu.
Click the Triggers
tab as shown below.
Note: The same dialog box opens when you click Add from the Triggers page of the Add Task Wizard. For more details, see Creating a Task Using the Wizard
Click the Add button. Another dialog appears as shown below:
Select the type of trigger you want to add click OK or simply double-click the trigger.
Enter the trigger properties in the dialog box that appears, and click OK. For more information on specific trigger properties, see All Available Triggers.
If you want to add additional triggers, click Add and repeat the process.
To edit or delete a trigger, select it on the triggers list and click Edit or Remove.
On the Task Administrator System
menu, click Enable Task Triggering.
When triggering is enabled, a check appears next to the menu selection. When triggering is disabled a message is displayed below the toolbar stating Task triggering is disabled. Select "System | Enable Task Triggering" or click here to re-enable.
