NS_E_WMP_UI_OBJECTNOTFOUND
Meaning at the producing boundary
The generated part of the What Is page already shows the standard AllStat description for this HRESULT. The additional test for the UI object not found condition is to record object type/ID, construction order and the first earlier error that prevented creation; that evidence is more useful than reinstalling the Player or changing several unrelated settings at once.
State worth preserving
Capture the UI object not found state before the Player advances, reloads, rescans or destroys the owning object:
- Decisive check: record object type/ID, construction order and the first earlier error that prevented creation.
- Artifact: control type, object ID and parent/child relation for the UI object not found reproduction.
- State: resource path, decoded dimensions and transparency/mapping attributes for the UI object not found reproduction.
- Object identity: event name, first handler and any duplicate handler declaration for the UI object not found reproduction.
- Underlying evidence: skin archive path, member list and selected.wms definition for the UI object not found reproduction.
- Correlation: THEME/version declaration and currentViewID for the UI object not found reproduction.
Reproduce without destroying evidence
- Preserve
0xC00D0FE5, the ErrorItem context and the object generation involved in UI object not found. - Compare the failing UI object not found artifact with a known-good artifact that differs only in the suspected property.
