UI_E_VALUE_NOT_DETERMINED
The scope of UI_E_VALUE_NOT_DETERMINED is Windows Animation Manager: the animation system could not derive the requested value from current state. Preserve 0x802A0006 beside the returning call before cleanup or retry creates a more generic secondary failure.
Wrong turns
UI_E_VALUE_NOT_SET is missing input; NOT_DETERMINED is unresolved evaluation despite an existing object graph.
Do not force evaluation by advancing time with arbitrary constants.
Object and state
A value may depend on unresolved keyframe time, transition duration, current storyboard state, or callback data. The object exists and may have inputs, but the requested result is not yet computable at this lifecycle point.
Capture before retry
- Requested value and evaluation time.
- Dependent keyframes or transitions.
- Storyboard status.
- Last callback output used in the calculation.
Controlled comparisons
| 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. |
Step-by-step investigation
The investigation should change one variable at a time and keep the original failing sample.
- First: Query only after the prerequisite timing state is established.
- Next: Reduce the dependency chain to one transition.
- Then: Record whether the same query succeeds after scheduling or update.
- Finally: Handle indeterminate output as a state, not as zero.
Closure criteria
Closure requires the query succeeds at the documented lifecycle point and remains intentionally unavailable before it; then repeat the next lifecycle operation to detect stale state.
