OLE_E_OLEVERB
OLE_E_OLEVERB: exact failure boundary
0x80040000 corresponds to OLE_E_OLEVERB. The platform message is Invalid OLEVERB structure. This result is returned while IOleObject:DoVerb or verb enumeration for an embedded object. The diagnostic question is whether the OLEVERB data or selected verb does not satisfy the object contract.
Evidence to capture
- Record this result, 0x80040000, the native method name, process and thread IDs, operation ID, component build, architecture, and elapsed time.
- Capture object generation, link or storage identity, activation state, advise cookie, window lifetime, and presentation format.
- Keep IErrorInfo, provider extended status, relevant device/storage events, and the first lower-level failure.
- When handling this result, unadvise only active cookies, release server and site interfaces in the documented order, and preserve storage if the user cancelled or output is uncertain.
Likely causes to separate
- The verb identifier is not supported.
- The OLEVERB structure contains invalid fields.
- A container caches verbs from a different server version.
Focused diagnostic test
Reproduce the same native call with the same object identity and change one cause candidate at a time. Preserve the first provider or lower-layer result and compare object state before cleanup. A different HRESULT after one controlled change is a new boundary, not proof that the original operation is fully repaired.
Correction
enumerate current verbs from the live object and invoke only a supported verb with valid window and rectangle data.
Verification
After correction, repeat the operation that returned this result. Verify the intended API operation completes and that any output, ownership transfer or persistent state is valid; do not treat disappearance of the dialog alone as success.
