IWMPNetwork::get_downloadProgress method (wmp.h)

  • Artikel

[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 It has been superseded by MediaPlayer.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 get_downloadProgress method retrieves the percentage of the download completed.

Syntax

HRESULT get_downloadProgress(
  [out] long *plDownloadProgress
);

When the Windows Media Player control is connected to a digital media file that can be played and downloaded at the same time, the get_downloadProgress method retrieves the percentage of the total file that has been downloaded. This feature is currently supported only for digital media files downloaded from web servers. The following file formats can be downloaded and played simultaneously:

  • Advanced Systems Format (ASF)
  • Windows Media Audio (WMA)
  • Windows Media Video (WMV)

In addition, some AVI files can be downloaded and played simultaneously.
