IWMPMedia::get_duration

The get_duration method retrieves the duration in seconds of the current media item..

Syntax

Parameters

pDuration

[out]  Pointer to a double containing the duration.

Return Values

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK The method succeeded.

Remarks

If this method is used with a media item other than the one specified in IWMPCore::get_currentMedia, it may not contain a valid value.

To retrieve the duration for files that are not in the user's library, you must wait for Windows Media Player to open the file; that is, the current OpenState must equal MediaOpen. You can verify this by handling the IWMPEvents::OpenStateChange event or by periodically checking the value of IWMPCore::get_openState.

For playlists, the duration of each media item can be retrieved when the individual media item is opened, rather than the when the playlist is opened.

Before calling this method, you must have read access to the library. For more information, see Library Access.

Requirements

Version: Windows Media Player 9 Series or later.

Header: Include wmp.h.

Library: Use wmp.dll.
