UI_E_STORYBOARD_ACTIVE
UI_E_STORYBOARD_ACTIVE belongs to Windows Animation Manager. It marks the requested operation conflicts with a storyboard that is still scheduled. The useful starting point is the exact API, object and state transition that returned 0x802A0101, because a shell or application message can hide that boundary.
Where this result is raised
An active storyboard remains part of the manager schedule even if a visual transition appears complete. Structural reuse or release-sensitive operations must respect its reported status and completion lifecycle.
Evidence worth collecting
- Storyboard status and schedule time.
- Completion callback or abandonment result.
- Attempted operation.
- Manager update time.
A controlled diagnostic sequence
- First: Query status before mutation or reuse.
- Next: Wait for completion or abandon through the supported API.
- Then: Use a new storyboard for overlapping work.
- Finally: Log the update that removes it from the schedule.
How to interpret comparison tests
| Control | Interpretation | Hold constant |
|---|---|---|
| Same operation, controlled environment | If the result follows one machine, account, volume, network, or device, environment matters. | Keep versions and identity explicit rather than comparing only the final message. |
What this code does not justify
UI_E_STORYBOARD_NOT_PLAYING is the opposite lifecycle mismatch for playback-only operations.
Do not infer inactivity solely from the current visual value.
Verification after correction
Treat it as corrected only when the operation is issued only after the storyboard leaves the active schedule, or uses a distinct storyboard; retain the original negative case so fallback cannot be mistaken for repair.
