Retrieving Task Property Examples

To retrieve the properties of a task, call ITaskScheduler::Activate to get retrieve the interface of the task object, then call the appropriate ITask method to retrieve the task property that you are interested in. The code examples listed at the bottom of the page show how to retrieve the different task properties.

The code examples listed at the bottom of the page show how to retrieve the properties that are unique to task objects. For other work item properties that also apply to tasks, see Retrieving Work Item Examples.

Note  In the following code example, all interfaces are released after they are no longer needed.

Note that if you are retrieving a string property (such as the application name, parameters, or working directory), you must call CoTaskMemFree to free the memory allocated for the returned string.

The following procedure describes how to retrieve a task property.

  1. Call CoInitialize to initialize the COM library and CoCreateInstance to get a Task Scheduler object. (These examples assume that the Task Scheduler service is running.)
  2. Call ITaskScheduler::Activate to get the ITask interface of the task object. (Note that this example gets the "Test Task" task.)
  3. Call the appropriate ITask method to retrieve the property you are interested in.
  4. Process the property as needed. (These examples print the property to the screen.)
  5. If the returned property is a string, call CoTaskMemFree to free the memory allocated for the returned string.
