A Mathematical Expression Calculator developed based on the grammar analyzer GOLD Parser and a parser Expression Calculator
Recently found a grammar analysis artifact, read the official website (http://goldparser.org/) after the introduction of the feeling very sharp look, so it was used to test some, write a Mathematical Expression Analysis of small programs, the supported mathematical operators are as follows:General calculation: +-*/^ sqrt sqrt2 (
LA2132, 32\64 channel G series USB Virtual Logic Analyzer has many advanced triggering functions, but many users do not use these triggering functions, the following describes the use of these features. Timing measurement: The captured data is displayed as a time series.Introduction to LVDS:LVDS is a low-voltage differential signal transmission, is a new technology to meet today's high-performance data transmission applications. Because it enables the

Based on the SQL Server 2000 query analyzer core, the single-file Green Edition tool is virtualized and encapsulated in person, you can quickly access the SQL server instance and execute SQL code scripts without installing SQL query analyzer on your machine or client server.
Tested in person, you can connect to the database instance engine of SQL Server 2000/2005/2008, which is perfectly compatible with
1. Lexical analyzer
Function: Read the input characters of the source program and form them into a word base to generate and output a lexical unit sequence.
Ii. Design Principles
1) symbol classification of c programming language: keywords, identifiers, constants, operators, operators
2) lexical analyzer Dual Output:
3) Regular Expression and state transition diagram
4) program description:

This article introduces a small open-source project: FLV Encapsulation Format analyzer. FLV, short for Flash Video, is a widely used Video encapsulation format on the Internet. Video websites such as Youtube and Youku all use FLV to encapsulate videos. My project is not large and can be used to learn the FLV Encapsulation Format Structure. In addition, it supports separating video streams and audio streams from FLV. Developed Using MFC of VC 2010. Dur
The following table lists all keyboard shortcuts provided by SQL Server Query Analyzer.
Activity shortcuts
Bookmarks: Clears all bookmarks. Ctrl-shift-f2
Bookmarks: Inserting or deleting a bookmark (toggle). Ctrl+f2
Bookmarks: Moves to the next bookmark. F2 function key
Bookmarks: Moves to the previous bookmark. Shift+f2
Cancel the query. Alt+break
Connection: Connection. Ctrl+o
Connect: Disconnect. Ctrl+f4
Connect: Disconnect and close child windows.
PrefaceIn daily development work, we always need to write some syntax analyzers from time to time. The syntax analyzer does not necessarily refer to the front-end of a language compiler, but may also be a read/write program for configuration files designed by itself, or a DSL (domain-specific language) that simplifies our development ). We can choose to use XML, but because XML is too noisy, it is necessary to write a syntax
. Okay. What is shift? When idlist0 jumps to idlist2, it must be moved to idlist. Idlist3 jumps to idlist1 and needs to be moved to ID. Idlist0 jump to idlist1 also needs to be moved to ID. That is to say,When the state transfer passes through a non-terminator edge, it will be moved to another grammar state machine.. Id1 and idlist1 are the final nodes of ID and idlist. They must follow the "removed from there" Rules and then jump to "idlist2 or idlist1 ". That is to say,Once you reach the final
It has been a long time since the previous version.
When V1.0 is used, it is called CYQ. IISLogViewer.
During V2.0, a Chinese name is given, which is:
Website log analyzer V2.0
After upgrading to 3.0, I changed the name:Autumn-style website log analyzer V3.0
Key points of this version upgrade:1: Overall upgrade to avoid the problem of automatic exit of software caused by thread conflicts. 2: analyze the f

To query the reason why analyzer cannot be debugged in one step, take the following steps:
1. set the server authentication attribute to hybrid mode (window and SQL authentication)
2. on the control panel, open service and open properties for the MSSQLSERVER service. on the logon page, set the logon identity to the local account and password of the server, such as administrator and password 123;3. restart the sqlserver service. at this time, the s
[Original] Microsoft baseline security analyzer tool Introduction
As we all know, when conducting security testing, you can start with deployment and infrastructure, input verification, identity verification, authorization, configuration management, sensitive data, session management, encryption, parameter operations, exception management, review, and logging.. Today I would like to recommend a free security leak scanning tool Microsoft Baseline

code. Note that we have set the lexical analyzer to ignore all whitespace characters, line breaks, and comments, which are considered for easy parsing. Readers can try to expand the lexical analyzer on their own, such as adding lexical constants, more keywords and operators, and even more new lexical characters than ever before. I wish you a happy practice! At the beginning of the next chapter, we want to
When I finished the lexical analyzer last week, I had a problem with a trivial but X-ache. After all, it is the first time to completely write the entire language of the compiler (so call it, the interpreter more reliable), due to lack of experience, in the string parsing this piece stopped two genius solved, here recorded for later reference. Oh yes, the reason why I want to own handwriting parser, not I do not know that there are automatic tools can
