With the increase of Windows Mobile devices, developers are very concerned about how to make applicationsProgramRun properly on devices with different screen sizes and resolutions.
Msdn has launched a new topic: adapt your app
This center provides the screen size and resolution specifications of existing windows
. The adapter model itself requires us to use the "interface-oriented programming" style as much as possible, so that it can be easily adapted at a later stage. [Cited above from MSDN Webcast]EffectFor class adapters:1. Match adaptee and Taget with a specific adapter class. The result is that when we want to match a class and all of its subclasses, class adapter will not be able to do the job.2. Allows adapter to redefine part of the behavior of Adapt

The development of 3.P2P streaming media broadcasting technology
Using Peer-to-peer technology to achieve large-scale streaming media on demand and live Broadcast system webcast appeared in 1998. Webcast uses a binary multicast tree to transmit
Thanks to all the love, many friends will encounter problems to Lao Zhao for questioning. However, in the process of reading a lot of friends, and in peacetime and other discussions, or in the garden articles often found some misuse of the concept of the situation. If there is no consensus on the concept, there will be many problems in work and communication. So while Lao Zhao has explained in other places (such as webcast or some articles), it still
LIVE555 has four main class libraries:
Libusageenvironment.lib;liblivemedia.lib;libgroupsock.lib;libbasicusageenvironment.lib
After the four class libraries and related header files are imported into vc++2010, the webcast system can be easily implemented.
Here directly affixed to the complete code, paste into the VC inside can be run.
Note: After the program is run, use the Player software (VLC Media player,ffplay, etc.), open url:rtp://239.255.42.42:

Code rate: The code rate indicates the bandwidth consumption of live broadcast, the higher the code rate, the greater the bandwidth consumption. When the bandwidth is insufficient, the live card will change, the net indicator in the live panel will turn red.
Lack of bandwidth tips:
Resolution: For the audience to see the live screen resolution, when the rate is high enough, the higher the resolution of the video clearer, while the CPU occupies higher. When the rate i
Since the project has not really started, but has been in contact with BI for more than half a year, preface, these days to get a simplified version of the BI project. On the one hand to the new bi beginners friend a reference, on the other hand also for their upcoming projects to prepare, so that they can take into account the details of some projects. We also want to provide some advice and experience for bi-research friends. Since our case was developed using Microsoft's sqlserver2005 BI plat

2. Turn off IP direct broadcast (IP directed broadcast)
Your server is very obedient. Let it do what it does, and no matter who sends the instructions. A smurf attack is a denial of service attack. In this attack, an attacker uses a fake source address to send an "ICMP echo" request to your
available/unavailable passwords, as well as a password reliability test.

your server is very obedient. Let it do what it does, and no matter who sends the instructions. A smurf attack is a denial of service attack. In this attack, an attacker uses a fake source address to send an "ICMP echo" request to your webcast address. This requires all hosts to respond to this broadcast request. This s

Compared with the simple way of downloading, this kind of streaming mode is not only shorten the startup delay greatly, but also reduce the demand of the system cache capacity. Another benefit of using streaming is that it makes it possible to transmit media data (such as live webcast, video co

Typically, a network firewall will have a security level option. For this choice, you must not choose. Because, a lot of users because not according to the actual situation of choice, and lead to the use of certain network resources or hackers.
For a fixed IP technical LAN user like me, I think it's set to medium. Because, we do not like some users can change their own IP, so our defense must be higher than the dynamic I
