[Reprint] different views of an MFC Document

MDI (multipledocument Interface) is a specification of the Windows interface. It establishes multiple windows to browse document data. For example, programmanager in Windows is implemented according to the MDI specification. In actual engineering software development, many programmers regard it as a standard method to implement multiple windows. Microsoft's basic library (MFC) is a powerful general-purpose

1 Basic Knowledge 1.1 MFC Document view structure program structure Overview When we use MFC Appwizard to generate an MFC program, we use all the default settings (of course, also multiple documents. This article mainly discusses the single document based on multiple documents, because the latter and the former have many similarities, but the former is more complex and more commonly used .), Assuming that your program is named A, you will get six classes: cmainframe, cchildframe, caboutdlg, cad

Selection of high-density optical fiber pre-connection system for data centers

or 10-core optical fiber, so the normal 40g and G optical fiber network communication is 8-core optical fiber and 20-core optical fiber. This poses a challenge to the traditional dual-core optical fiber transmission of data communication, that is, the use of high-density multi-core optical fiber, but even so, it is not necessary to use a high-density multi-core optical fiber pre-connection system. Let's look at the third reason, which is more realistic, that is, the familiar Optical Fiber Conn

For example, the two-day closing price of a stock may be the same, but the fluctuation in one day is not large, but the share price on the other day is more than 10%, the analysis significance of the two-day market trend is definitely different, which is hard to show in mo

Jumper Test Adapter

The new stricter TIA standards and Cat 5e/Class D and Cat 6/Class E high-speed data cable systems have higher requirements for jumpers than ever before. Currently, Fluke network provides the most convenient jumper testing method. Simply connect the sturdy and compact patch cord test adapter to the DSP-4X00 cable analyzer and download the test database, you will have a high-speed, fully automated patch cord

Jumper: the main character ignored in Integrated Wiring

in increased costs. In some projects, the construction personnel often use the discarded twisted pair wires during the construction, from the market to buy ordinary crystal head to make their own jumper, but the British Ida news here is not recommended to make their own jumper, there are several main reasons: 1. Self-made cat6 jumpers cannot be tested by components of a single product in TIA/EIA, 2. In the channel test, self-prepared Jumpers are used for testing. In the whole channel, even if o
