DirectShow is a member of DirectX, it is used for audio and video data collection, multimedia file playback, and other applications. The most basic functional module in DirectShow is filter (each rectangle block in Figure 6 represents a filter).

Best practices for the search box:
The search box must be available on all pages, not the homepage.
The search box must be long enough (such as Google's) for users to conveniently view and modify.
The search box must be intelligent. When searching, users can provide similar "common search terms" for their reference. In addition, when you enter a word, you can directly provide some "recommendation results" below 」. The search on the Apple official website is a goo
, making the data transmission configuration simpler;
2 queues in the queue Manager can be specified as Cluster shared queues, visible to all queue managers in Cluster, and Cluster shared queues defined in different queue managers automatically implement load balancing for the queue;
3 a master-slave relationship can be specified between broker agents of different queue managers, so that tree-like pub/sub structures can be conveniently implemented in Cluster.
Once you have configured WebSpher
, search is meaningful. In particular, like Wikipedia, which has a large number of different areas of content of the site, "search" function is necessary.

For devices that support mobile storage (such as USB flash drives, SD cards, and CF cards), I think Autorun technology is a very powerful method. Then, it runs. It is very simple but practical, similar to the CD/DVD Autorun technology. Windows Mobile directly supports Autorun. In fact, it is easy to implement on Windows CE: runtime runs.
To implement this function, you must first create a message queue during initialization to wait for the system device plugging time notification:Code
