OLEOBJ_S_INVALIDVERB
OLE object rejected an invalid verb without generic failure
OLEOBJ_S_INVALIDVERB is HRESULT 262528 (0x00040180) from winerror.h. AllStat describes this result as “Invalid verb for OLE object.” The high-order severity bit is clear, so this is a success result, but it carries more information than plain S_OK.
The requested OLE verb number is not valid for the object, and the caller must choose a supported verb rather than treating activation as globally broken.
Where the result is encountered
- This result can appear in IOleObject::DoVerb calls; record the producing interface and method rather than inferring behavior from the symbolic name alone.
- This result can appear in container menus built from object verbs; record the producing interface and method rather than inferring behavior from the symbolic name alone.
- It can appear in automation code invoking primary, show, open, hide, or custom verbs; record the producing interface and method rather than inferring behavior from the symbolic name alone.
The same numeric success value can be mishandled when a wrapper exposes only a Boolean. Keep the original HRESULT until the code-specific outputs and state transition have been evaluated.
Diagnostic sequence
- capture the raw HRESULT
0x00040180immediately after the returning method and record whether the caller usedSUCCEEDED,FAILED, equality testing, or exception translation. - Identify the exact owner of it: interface, method, object instance, provider or filter version, thread or apartment, and operation phase.
- Validate the decisive contract boundary for it: the verb identifier exists in the object registration or EnumVerbs result for the current object class and state.
- inspect every output parameter, count, status array, returned interface, or side effect that the method documentation associates with this success-with-information result.
- Compare the observed state before and after it; do not assume that a success severity bit means every optional sub-operation completed.
- reproduce the smallest request with the same object state and then change only the condition identified by the evidence before repeating the operation.
State boundary that must be proved
The central question for it is whether the verb identifier exists in the object registration or EnumVerbs result for the current object class and state. The HRESULT alone confirms neither unrelated work nor the quality of optional outputs.
A reliable interpretation of it names the exact method contract, the object generation, and the outputs that remain valid. This prevents a success-with-information result from being promoted to full success or demoted to a generic error.
Correct handling, retry, and recovery
Refresh the supported verb list and invoke a valid alternative. Do not repeatedly retry the same invalid verb or unregister the class based on this status alone.
Retry it only when the recorded state can change the documented outcome. Repeating the same call is inappropriate for a stable end marker, cancellation, unsupported format, adjusted property, or partial result whose completed side effects have not been reconciled.
Evidence and telemetry to preserve
- preserve requested verb value.
- preserve CLSID and server version.
- preserve enumerated OLEVERB entries.
- preserve object running and in-place-active state.
- preserve container window and client-site information.
Also record oleobj_s_invalidverb_operation, oleobj_s_invalidverb_object, oleobj_s_invalidverb_state_before, oleobj_s_invalidverb_state_after, UTC time, process and thread identifiers, and a correlation ID. Keep secrets out of logs while retaining GUIDs, CLSIDs, media subtypes, property IDs, row identities, and hashes needed to distinguish objects.
Difference from nearby HRESULT values
OLEOBJ_S_CANNOT_DOVERB_NOW means the verb is valid but temporarily unavailable; it means the identifier itself is not accepted.
This distinction determines whether the caller should consume partial outputs, stop iteration, wait, reconfigure, notify the user, or perform no error recovery at all.
Developer and administrator guidance
Application telemetry should separate terminal failure, ordinary success, partial completion, continuation, cancellation, and warning-like success. Support bundles should contain the smallest reproducible call and the effective configuration seen by the owning component.
A support report for it should include decimal 262528, hexadecimal 0x00040180, the AllStat meaning, the owning API, and the first detailed status or output that explains why the method did not return ordinary S_OK.
Practical validation scenario
A toolbar caches a custom verb from an older server version. After upgrade the verb is absent, so the container receives it, rebuilds its menu from EnumVerbs, and uses the primary verb.
The negative test should preserve the condition that produces it; the recovery test should alter only that condition and verify the final state as well as the HRESULT.
