OLE_E_NOCACHE

OLE object has no presentation cache for the operation

OLE_E_NOCACHE is HRESULT 2147745798 (0x80040006) from winerror.h. AllStat describes it as “There is no cache to operate on” The result belongs to IOleCache, IViewObject, or container presentation handling. The important boundary is not merely failure but which object and state transition established: the object does not contain the cache entry or cache object required by the request.

The decisive meaning of this result is that the object does not contain the cache entry or cache object required by the request. The severity bit does not decide handling; the controlling fact is that the object does not contain the cache entry or cache object required by the request. Interpret it at the native boundary before a wrapper hides the condition that the object does not contain the cache entry or cache object required by the request.

Where the result appears

This result can surface in a compound-document containers, embedded or linked objects, OLE activation, advising, caching, conversion, and persistence.
map the failure to one concrete operation among IOleObject, IOleLink, IOleCache, IAdviseSink, IPersistStorage, IOleInPlaceObject, monikers, verbs, and client-site callbacks.
Preserve CLSID, object and client-site identity, storage or moniker, advise cookie, verb, activation state, window generation, and presentation format before releasing or replacing the object that returned this result.

An incident record for this HRESULT must distinguish caller, runtime, provider, and backing resource while testing whether the object does not contain the cache entry or cache object required by the request.

Typical causes and interpretation boundary

The immediate contract boundary is specific: the object does not contain the cache entry or cache object required by the request. Common cause branches include the following:

The requested FORMATETC was never cached.
Cache initialization was skipped.
The cache was discarded during conversion or reload.

Confirm the cause branch that explains why the object does not contain the cache entry or cache object required by the request by using call arguments, object state, metadata, device information, or provider traces.

Correct handling and recovery

The primary recovery is to create the required cache entry or obtain a live presentation from the running server, then persist it if offline display is needed. The result failure report should expose enough IOleCache, IViewObject, or container presentation handling state to understand why the object does not contain the cache entry or cache object required by the request without a production debugger.

Retry this result only when evidence shows the state behind “the object does not contain the cache entry or cache object required by the request” can change and the operation is repeatable. Reconcile persistent, remote, device, or ownership state before repeating it.

Practical scenario

A document tries to draw an embedded object while its server is unavailable, but no metafile presentation was cached during save. Record the decisive state for this HRESULT and verify recovery on a fresh object or request generation.

Difference from related HRESULTs

CACHE_E_NOCACHE_UPDATED concerns failure to update cache entries; it says there is no cache to operate on Tests and telemetry should preserve that boundary for this HRESULT.

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. Build a small container/server fixture that covers loaded, running, in-place active, UI-active, static, linked, and shutdown states.

Administrators should repair the component owning IOleCache, IViewObject, or container presentation handling as a versioned unit instead of copying arbitrary DLLs. Repair for this HRESULT should target only the evidence-backed component, provider, document, device, or configuration.
