D2DERR_NO_SUBPROPERTIES
The scope of D2DERR_NO_SUBPROPERTIES is Direct2D effect registration and property metadata. The caller requested a nested Direct2D property where no such subproperty exists. Keep 0x8899002A beside the returning method because a wrapper can replace this distinction with a generic subsystem message.
Start with the returning API
When it is returned, effect registration is scoped to a factory and CLSID, while effect properties form a metadata hierarchy of names, indices, types, and optional subproperties. An unregistered CLSID, absent property, and absent child property occur at different lookup stages and should not share one generic fallback.
Inspect the following boundary: property path traversal after a valid parent property.
Limits of this code
INVALID_PROPERTY rejects the main property; NO_SUBPROPERTIES is narrower and applies after reaching a parent that has no requested child. Do not respond with a universal render-target recreation loop unless the returned status specifically documents device-loss recovery; graph, property, numeric, lifetime, and print-state errors require correcting their contract.
Diagnostic evidence matrix
| Record | Why it matters here |
|---|---|
| Full property path and parent index | In this result diagnostics, recording full property path and parent index ties the HRESULT to the Direct2D effect registration and property metadata boundary rather than to the final visible failure. |
| Parent property type and metadata | Comparing parent property type and metadata shows whether this result follows input, object state, or environment. |
| Effect CLSID and registration XML | Preserving effect CLSID and registration XML provides the evidence needed to test this distinction: iNVALID_PROPERTY rejects the main property; NO_SUBPROPERTIES is narrower and applies after reaching a parent that has no requested child. |
| Lookup method and returned index | Recording lookup method and returned index separates the Direct2D effect registration and property metadata boundary from a later wrapper symptom. |
Reproduce without destructive cleanup
Track successful registration on the same factory, enumerate properties from the exact effect instance, resolve the parent before a child, and use the canonical CLSID and property path in diagnostics.
- When it is returned, resolve the parent property first.
- Enumerate its subproperties before lookup.
- use the direct property if it is scalar.
- When it is returned, test custom registration metadata for nested fields.
Useful comparison axes
| Test | Interpretation | Hold constant |
|---|---|---|
| Same environment, reduced input | If this result disappears with a smaller faithful case, complexity within Direct2D effect registration and property metadata is implicated. | Keep full property path and parent index fixed while simplifying effect CLSID and registration XML. |
| Same input, fresh object generation | If this result changes after rebuilding state, examine ownership across the caller’s object graph, custom effect or renderer, Direct2D validation layer, backing device, and deferred draw boundary. | Place parent property type and metadata on the timeline of the last successful transition. |
| Same operation on a controlled second path | If this result follows one environment, the failure is not explained by source data alone. | Compare adapter and feature level, factory and device generations, target identity, debug-layer output, and thread ownership while preserving lookup method and returned index. |
What success must demonstrate
A correction for it should let the operation at the Direct2D effect registration and property metadata boundary complete repeatedly under the original supported conditions. Repeat the control that begins with “Resolve the parent property first” and confirm that the following lifecycle step also succeeds. Keep the original failing sample and one deliberate negative case so fallback cannot be mistaken for repair.
