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 It has been superseded by MediaPlayer.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

Note This section describes functionality designed for use by online stores. Use of this functionality outside the context of an online store is not supported.

The VerifyPermission method initiates the process of verifying permission for Windows Media Player to perform an action.

HRESULT VerifyPermission(
  [in] BSTR    bstrPermission,
  [in] VARIANT *pContext
);

Parameters

A BSTR that specifies the action for which permission is being requested. See Remarks for a list of possible values.

The VerifyPermission method initiates a permission verification and then returns immediately. When the online store has completed the verification, it calls IWMPContentPartnerCallback::VerifyPermissionComplete to notify Windows Media Player that permission has been granted or denied.

The following list gives the possible values for bstrPermission along with the corresponding meanings of pContext.

g_szVerifyPermissionSync
