DRM_LICENSE_STATE_CATEGORY enumeration (Drmexternals.h)

  • Άρθρο

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The DRM_LICENSE_STATE_CATEGORY enumeration type defines the categories for DRM license strings that are displayed to the user.

  WM_DRM_LICENSE_STATE_COUNT,
  WM_DRM_LICENSE_STATE_FROM,
  WM_DRM_LICENSE_STATE_UNTIL,
  WM_DRM_LICENSE_STATE_FROM_UNTIL,
  WM_DRM_LICENSE_STATE_COUNT_FROM,
  WM_DRM_LICENSE_STATE_COUNT_UNTIL,
