IWMPSettings::put_autoStart method (wmp.h)

[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 It has been superseded by MediaPlayer.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.]

The put_autoStart method specifies a value indicating whether the current media item begins playing automatically.

Syntax

HRESULT put_autoStart(
  [in] VARIANT_BOOL fAutoStart
);

Parameters

[in] fAutoStart

VARIANT_BOOL indicating whether the current media item begins playing automatically. The default is TRUE.

Return value

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

The put_autoStart method for the full mode of Windows Media Player can be set globally by external events (such as loading a CD). Therefore, there is no reliable default value for skins and remoted Player controls. This is because the playback engine of the full mode Player is used in both cases.

You should set put_autoStart to FALSE immediately before you set IWMPCore::put_URL, IWMPCore::put_currentPlaylist, or IWMPCore::put_currentMedia in skins and remoted Player controls if you wish to ensure that the media item does not start playing immediately. Also, unless you set put_autostart to TRUE immediately before specifying a media item, you should not rely on this setting as a substitute for using the IWMPControls::play method.

Requirements

Minimum supported client Windows Media Player 9 Series or later.
