RemoveScheduledTask is being phased out in favor of TaskRemove, which was introduced experimentally in Version 11.2.

RemoveScheduledTask[obj]

removes obj from the list of currently scheduled local or cloud tasks.

Basic Examples  (7)

Create a task that removes itself:

Wolfram Language code: RunScheduledTask[RemoveScheduledTask[$ScheduledTask]]

Create a task:

Wolfram Language code: n = 0; RunScheduledTask[n++, {1, 3}];
Wolfram Language code: n
Wolfram Language code: ScheduledTasks[]

Remove the task:

Wolfram Language code: RemoveScheduledTask[ScheduledTasks[]]

Remove the task automatically when it is not needed:

Wolfram Language code: RunScheduledTask[x = DateString[]];
Wolfram Language code: ScheduledTasks[]
Wolfram Language code: Dynamic[x]
Wolfram Language code: RunScheduledTask[x = Graphics[{Red, Disk[]}];RemoveScheduledTask[$ScheduledTask], 2];

The second task was automatically removed:

Wolfram Language code: ScheduledTasks[]
Wolfram Language code: RemoveScheduledTask[ScheduledTasks[]];

Non-synchronized tasks:

Wolfram Language code: i = 0; RunScheduledTask[++i, 1]; RunScheduledTask[i = 0, 4]; Dynamic[i]

Better synchronization:

Wolfram Language code: j = 0; StartScheduledTask[{CreateScheduledTask[++j, 1], CreateScheduledTask[j = 0, 4]}]; Dynamic[j]
Wolfram Language code: ScheduledTasks[]
Wolfram Language code: RemoveScheduledTask[ScheduledTasks[]];

Create a task that runs only once and removes itself after finishing:

Wolfram Language code: RunScheduledTask[Print[RandomReal[]];RemoveScheduledTask[$ScheduledTask], 0];
Wolfram Language code: ScheduledTasks[]

Create a task that removes itself once a condition is met:

Wolfram Language code: RunScheduledTask[With[{x = RandomReal[]}, Print[x];If[x > 0.6, RemoveScheduledTask[$ScheduledTask]]], 1];

Create a task that removes itself when an external variable is changed:

Wolfram Language code: x = 0;RunScheduledTask[Print[RandomReal[]];If[x ≥ 1, RemoveScheduledTask[$ScheduledTask]], 1];

Cause the task to be stopped and removed:

Wolfram Language code: x = 1
