In the project, we have the need to record the screen, there are several ways to record the screen, can be based on Windows API BitBlt, FFmpeg Avdevice, DirectX and QT, this article explains the QT5-based capture screen. The advantages of QT relative to other kinds of screen-catching are better cross-platform, simple interface, inferior to DirectX capture screen, but DirectX can only be windows. After testing DirectX capture screen speed is the fastest, the other interface speed is basically the

. Because generally speaking, the smaller the office size, the fewer users, the lower the risk faced. As a result, simple packet-filtering firewalls are sufficient for small offices, such as those that are randomly brought by many DSL or cable routers. These include broadband routers from companies such as D-link, 3Com, Netgear and Linksys. In addition, WatchGuard Firebox Soho, Symantec Firewall 100, global technology company Gnat, NetScreen and SonicWALL SOHO and other firewalls are fully appli

Although this may not be the point of positioning it, it is indeed a flaw and exists in the Vista RC2. When using a picture as a desktop wallpaper, Windows Vista is responsible for maintaining the aspect ratio of the image, but when compared to Windows XP, when the image is stretched to fit the screen resolution, Vista does not interpolate the image so that it appears jagged. In the following two graphs, the left is an example of the problem that shows a clear lack of interpolation (that is, com
