Starting the Downloads
[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 It has been superseded by MediaPlayer.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 downloading starts when the user clicks Download. This button is named btnDownload in the code and the event handler function for the onClick event is named "OnDownload".
"OnDownload" first creates a new empty DownloadCollection object and assigns it to a local variable.
oDLC = g_oManager.createDownloadCollection();
Next, the function starts each of the five items downloading and stores the returned DownloadItem object in an array.
g_DLI[0] = oDLC.startDownload(g_sFiles[0], g_sDLType);
g_DLI[1] = oDLC.startDownload(g_sFiles[1], g_sDLType);
g_DLI[2] = oDLC.startDownload(g_sFiles[2], g_sDLType);
g_DLI[3] = oDLC.startDownload(g_sFiles[3], g_sDLType);
g_DLI[4] = oDLC.startDownload(g_sFiles[4], g_sDLType);
The code then updates the user interface elements with the information about the download collection and its download items.
