STG_E_INVALIDHANDLE

Structured-storage object or handle is invalid

STG_E_INVALIDHANDLE is HRESULT 2147680262 (0x80030006) from winerror.h. AllStat describes it as “Attempted an operation on an invalid object.” The result belongs to use of a storage, stream, enumerator, lock-bytes object, or underlying handle. Interpret this result at the native boundary before a wrapper hides the condition that the operation references an object identity that is no longer valid for the requested storage call.

The decisive meaning of this result is that the operation references an object identity that is no longer valid for the requested storage call. The severity bit does not decide handling; the controlling fact is that the operation references an object identity that is no longer valid for the requested storage call. The symbol it is useful only when tied to the method and lifecycle phase where the operation references an object identity that is no longer valid for the requested storage call.

Where the result appears

  • This result can surface in a IStorage, IStream, ILockBytes, property storage, compound-file parsing, or persistence code.
  • map the failure to one concrete operation among StgOpenStorage, StgCreateStorageEx, IStorage, IStream, IPropertyStorage, STATSTG, and the selected STGM mode.
  • Preserve storage path or identity, STGM mode, stream or storage name, transaction generation, file hash, and backing provider before releasing or replacing the object that returned this result.

An incident record for it must distinguish caller, runtime, provider, and backing resource while testing whether the operation references an object identity that is no longer valid for the requested storage call.

Typical causes and interpretation boundary

The immediate contract boundary is specific: the operation references an object identity that is no longer valid for the requested storage call. Common cause branches include the following:

  • The caller retained an interface after its parent storage was reverted or closed.
  • A native handle was closed or replaced before the COM wrapper used it.
  • Memory corruption changed the object or handle value.

Confirm the cause branch that explains why the operation references an object identity that is no longer valid for the requested storage call by using call arguments, object state, metadata, device information, or provider traces.

Correct handling and recovery

The primary recovery is to reacquire the object from the current parent generation and fix lifetime ownership rather than reusing the stale reference. The result failure report should expose enough use of a storage, stream, enumerator, lock-bytes object, or underlying handle state to understand why the operation references an object identity that is no longer valid for the requested storage call without a production debugger.

A UI loop must not repeat it without refreshing the state behind “the operation references an object identity that is no longer valid for the requested storage call” and checking for prior side effects. Reconcile persistent, remote, device, or ownership state before repeating it.

Practical scenario

A background saver keeps an IStream pointer after the document storage is replaced during reload, then attempts to commit through the obsolete stream. Record the decisive state for it and verify recovery on a fresh object or request generation.

Difference from related HRESULTs

STG_E_REVERTED identifies invalidation by a storage revert; it is broader and does not prove that revert caused the invalid object Tests and telemetry should preserve that boundary for it.

Developer and administrator guidance

Developers handling it should make object lifetime and state transitions explicit, preserve the native HRESULT, and keep cleanup paths safe when initialization or output is partial. Exercise direct and transacted modes, read-only and writable paths, cancellation, malformed input, and cleanup after partial output.

Dashboards should keep it distinct and attach dimensions that can prove or disprove: the operation references an object identity that is no longer valid for the requested storage call. Repair for it should target only the evidence-backed component, provider, document, device, or configuration.
