TPC_E_NOT_RELEVANT
Meaning and numerical form
TPC_E_NOT_RELEVANT is HRESULT 2147746354 (0x80040232; signed -2147220942). AllStat records its meaning as “TabletPC inking error code. The data required for the operation was not supplied”. In practical terms, it is returned when a Tablet PC operation lacks the particular ink, context or recognition data required for that operation.
The severity bit in 0x80040232 is set, so this result is a failure result rather than a success or informational status. Its facility is 4 (FACILITY_ITF) and its low 16-bit code is 562 (0x0232). Those fields classify the value but do not identify the component instance, call, object or input that produced it.
Evidence to collect
A useful diagnostic record for this result includes the native API or interface method, component or CLSID, process and thread IDs, architecture, apartment where relevant, operation correlation ID, elapsed time, input identity, and the first state-changing event before failure. When diagnosing it, preserve IErrorInfo, an inner HRESULT, Win32 status, device event or provider message when available.
- Capture 1 for this HRESULT: requested operation and exact required data set.
- Capture 2 for this HRESULT: stroke count, packet properties and recognition-context configuration.
- Capture 3 for this HRESULT: context-node type or plug-in stage receiving the call.
Telemetry for this HRESULT should retain types, lengths, hashes, stable opaque identifiers and lifecycle generations while redacting content and credentials. This makes repeated incidents comparable without exposing ink content, packet data, account details or recognizer input.
Where the failure belongs
This result belongs to Tablet PC ink, stylus and recognition. Tablet PC APIs span device enumeration, RealTimeStylus packet queues, ink-object lifetime and recognizer-specific capabilities. The numerical facility does not identify which Tablet PC layer produced the result. The decisive condition is this: a Tablet PC operation lacks the particular ink, context or recognition data required for that operation. Record the first native producer instead of relying only on a framework exception translated several layers later.
Do not infer from this result alone that reinstalling, rebooting or repeating the whole workflow is appropriate. Because it can cross process and language boundaries, its correction depends on the object identity, lifecycle generation, input and state at the first failing call.
Likely causes
- Possible cause 1 for this HRESULT: the selected strokes do not contain the requested property.
- Possible cause 2 for this HRESULT: recognition context was not supplied with ink or guide data.
- Possible cause 3 for this HRESULT: the operation is valid only for another context-node or input type.
Diagnostic sequence
- Capture it at the first native return and identify the exact object and method.
- Confirm that the observed path matches this condition: a Tablet PC operation lacks the particular ink, context or recognition data required for that operation.
- compare the live state with the method contract before changing configuration.
- collect the code-specific evidence listed above and preserve any more specific preceding error.
- change one evidence-backed cause at a time, then repeat the smallest operation that can prove the correction.
- Add a regression check that distinguishes it from the related outcomes described below.
Correction and retry boundary
- Corrective action 1 for this HRESULT: check applicability before invoking the operation.
- Corrective action 2 for this HRESULT: supply the documented data in the required order.
- Corrective action 3 for this HRESULT: treat absence as a branch in the feature contract rather than fabricating placeholder data.
Retry guidance for this HRESULT. Retry only after relevant data has been added or a different applicable operation is selected. A retry must avoid this hazard: replay stale strokes, reorder stylus packets or reuse an invalid recognizer context. It must also preserve the evidence needed to locate the original producer of it.
Difference from nearby HRESULTs
TPC_E_INVALID_PROPERTY identifies a property lookup problem; it says the broader data needed for the operation was not supplied. Keep these outcomes separate in logs, exception mappings, user messages, dashboards and automated retry policy.
Developer and operational guidance
Code handling it should log the failed stage before cleanup, keep ownership and lifecycle transitions explicit, and avoid converting every failure into a generic message. Tests for this HRESULT should cover the primary cause, one adjacent HRESULT and the retry boundary so a future change cannot turn a deterministic contract failure into an uncontrolled loop.
Operational repair for this HRESULT should use supported device, Tablet PC component, recognizer and application lifecycle paths. Avoid unsupported configuration edits or component replacement unless evidence identifies that layer. Retain the original trace and a post-fix trace so the result can be attributed and the change reversed.
Practical scenario
A gesture analysis step runs on an empty stroke collection after filtering removed all ink; skipping analysis prevents it. The result scenario narrows the result to a reproducible contract boundary and supplies a concrete before-and-after test.
