IP packet. Isn't it a waste of bandwidth and resources?
Moreover, our network devices cannot identify the authenticity of ARP packets. If we send packets in ARP format, the computer will respond accordingly as long as the information is valid.
Imagine if we refresh the list in our ARP cache based on the corresponding content of the ARP response package, isn't it possible for us to play some ARP packet tricks in a network without security protection? In the subsequent articles, I will teach yo

The following describes the differences between different Ethernet formats through specific data packets.

The Ethernet version 2 is earlier than the IEEE standard Ethernet version.
From the data packet, we can see that EthernetV2 ident

How to connect to the SS database through ODBC
16:52:30 | category:Progress | font size subscription
Odbc ss odbc is not common and requires special ODBC tools and software to connect. The most commonly used tool is merant ODBC. Here we will introduce how to connect to progress database with merant3.7, because there may be different operating systems, of course the connection methods are somewhat different. to use merant3.7, you must install the SS database on the client.

Hello everyone, I'm Qin Yuanpei. Welcome to follow my blog. My blog address is blog.csdn.net/qinyuanpei.
Today, I want to share with you the dynamic shadow in Unity3D. I have relived my favorite game "Gu jianqitan 2" and found that the game has added three free DLC versions after the update. These three DLC types are mainly used to expand the Main Line Plot. the favorite of bloggers here is the seventh day

Traditional stand-alone games are usually sold to game players in the form of a game disc, players can not get more game content after purchasing the game, players only in a limited capacity of the game CD-ROM constantly repeated to find the fun of the game.

Undoubtedly, this mode is not conducive to game developers adding new content to the game. However, today, with the gradual maturity of internet technology, after buying a real game
to ensure that read and write are thread-safe.This is defined in the c++0x draft for bit field:A continuous number of non-0bit bit fields belong to the same memory location, and a bit field with a length of 0bit will take up a separate memory location. Reading and writing to the same memory location is not thread-safe, and reading and writing to different memory location is thread-safe.For example, in the example Bf1 and BF2 are the same memory location,bf3 is a separate memory location,

The gameplay of the entire game, then, relies heavily on the sequence of calls to the module, that is, when, where, what type of enemy is being produced, and what mobile strategy to use.The different call sequences are generally reflected in various levels, mods, and even game DLC, so it makes sense to organize call sequences effectively.

In fact, we have not used real reports here. The reportviewer control in is just a container for report presentation.
Next we need to create a report:
