Buffering a media content, while playing the other one in WMP fantom 12/27/2008 1:57:01 AM Hi all, I am developing an application in C# that has a form with Windows Media Player embedded inside. There are several links to some online content in my app. and I want user to change the content from one to another with a button click. Since WMP spent some time while buffering for the next content, I want to continue playing the current content. There is an event called "Buffering" in AXWindowsMediaPlayer class that signals when media player finishes buffering the content. But I could not achieve this with a single AXWindowsMediaPlayer object. Whatever I did, I could not continue to play the first content while buffering the second. Any ideas? Thanks in advance.

WMP can only open 1 media at a time so you need to use 2 players and swap them. Seamless source switching is generically complicated and requires a lower level approach than WMP. Even using DirectShow (which is what WMP uses internally), you would still need multiple graphs, which is complex to begin with, even more so in C#, since DS is designed to be used in C++. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm

You can quite easily hide/show windows using Framework classes. Regards, Vladimir V.
