NS_E_ASX_NOTHING_TO_WRITE
Understanding NS_E_ASX_NOTHING_TO_WRITE in a Windows Media playlist
NS_E_ASX_NOTHING_TO_WRITE (0xC00D106C) is returned when the serializer was asked to save an ASX playlist that contains no serializable entries.
Distinguish in-memory Playlist state, WPL or ASX parsing, nested-list expansion, Media-object resolution and execution of referenced items. Here, the decisive boundary is the serializer was asked to save an ASX playlist that contains no serializable entries. This result is most useful when treated as a Player checkpoint, not as a recommendation to reinstall everything.
Playlist boundary
AllStat already supplies the standard user-facing description for it; this custom block instead isolates the additional technical boundary. Earlier success in file lookup, network connection, parser creation or graph construction does not prove that the later the operation is valid.
Case-specific checkpoint: playlist count, item types, transient entries, unresolved Media objects and output path. The controlled comparison for it is: insert one local Media item into a fresh Playlist object and save to a writable new file.
Closest distinction: NS_E_WMX_PLAYLIST_EMPTY can block an action on an empty runtime list even when no serialization was requested.
Evidence from the list model
| Capture | Why it matters for it |
|---|---|
| Object or resource | playlist count, item types, transient entries, unresolved Media objects and output path |
| State snapshot | Record the Player openState/playState or operation phase, object identity and exact timestamp when this result was returned. |
| First lower result | Keep the earliest Win32, Winsock, COM, parser, codec, DRM or device result that appears before this result. |
| Comparison record | Use one known-good case that follows the same API, protocol and component path while changing only the rejected precondition. |
Minimal playlist experiment
- Record
0xC00D106C, this result, the exact method or command and the first failure time. - Preserve playlist count, item types, transient entries, unresolved Media objects and output path.
- Perform one isolated comparison: insert one local Media item into a fresh Playlist object and save to a writable new file.
- Repeat the original Player path after it and keep any new HRESULT as a downstream result.
- confirm the expected state transition rather than only disappearance of the dialog.
What the result means
| Retest outcome | Interpretation |
|---|---|
| Same it on the same object | The governing state or value is unchanged, or the caller is reusing an object created before the relevant change. |
| Fresh object succeeds | Lifetime, cached configuration or stale playlist/graph state contributed to it. |
| A later HRESULT appears | The rejected condition — the serializer was asked to save an ASX playlist that contains no serializable entries — was cleared for it; diagnose the new code at its own layer. |
| Only one item or endpoint fails for it | The evidence favors resource-specific data, rights, routing or device state rather than a global Player failure. |
Actions that obscure the cause
- creating an empty destination file before calling save.
- Do not discard the first occurrence by repeatedly invoking Play, open, save or retry; later events can replace its original state.
- do not publish credentials, private URLs, license material or complete protected-content headers; retain only redacted identifiers, lengths, hashes and protocol fields.

Close it only when the original operation crosses this boundary and reaches the expected next Player state.
