Syntax check, constant merging and the new idiom method tree are implemented in reduce normalization functions.

Search engine website indexing check program implemented by Asp. Net and asp, asp.net Search Engine
Use asp.net or asp to check whether an article is indexed by search engines such as Baidu, Google, and sogou.
Implementation principle: directly search for the url address of your article (without the protocol, but the a

Delete the index, delete the documentDelete index name/table/ID delete a specified document in the indexDelete index name deletes a specified index#删除索引里的一个指定文档DELETE jobbole/job/1# Delete a specified index delete jobbo
Use asp.net or ASP to check a URL address, an article is search engine, such as Baidu, Google, Sogou included.
Implementation principle: Direct search your article URL address (without agreement, but the agreement also line, the code will automatically remove protocol content), if the index will return the search results, or will be prompted to find information.

Personal Summary:A JavaScript engine is implemented by a standard interpreter, or by an instant compiler.Interpreter (interpreter): interprets one line and executes one line.Compiler (Compiler): all compiled into machine code, unified execution. (reduces the overhead of switching and scheduling, faster.) )The V8 engine is an instant compiler.Optimization strategy
The template engine xtemplate is an engine similar to the T4 design. It basically functions the same as T4 (the template syntax is fully compatible with T4, And the template header instruction is partially compatible ).
You can design a template engine for multiple scenarios, such as code generators, website templates,
, nothing more than to find and then continue slightly.
Support? Omit some bytes of code omitted, nothing more than change the function.
Code is very messy, indeed, I always do not like to arrange neatly, or how the Bug (funny)
This code is separated from the hexadecimal editor code, because the original control is use
Real-time check of account registration code is a feature that is currently used in WEB applications. This is mainly for user experience, don't wait for the user to submit the data and tell the other party that the data has been registered. This is very good. We can verify it after the user input. Here is a simple example. Real-time check of account registration
The main thing to read these code is to understand the objects that manipulate binary data in ASP adodb.stream! This procedure is mainly used is adodb.stream, if you have this basis, you can further add more features such as adding miscellaneous points, gradient background, the number of dislocation, strokes short points, improve the recognition of the impossible by OCR. There is no good identification engine
Static check:Static tests include code checking, static structure analysis, code quality metrics, and so on. It can be done manually, give full play to people's logical thinking advantages, can also be automated with the help of software tools. Code Inspection Code inspection including
-project.properties under the source code root directory to be analyzed (consistent with the repository URL), at least including:

transaction-safe (acid-compatible) storage engine with Commit, rollback, and crash resiliency.InnoDB locks the row level and also provides an Oracle-style, non-locking read in the SELECT statement, which adds multiuser deployment and performance. There is no need to widen the lock in the InnoDB. Because the row-level lock in InnoDB is suitable for very small spaces.InnoDB also supports foreign key coercion. In the SQL query. You are free to mix table
Template engine xtemplate is an imitation T4 design engine, functionally basic and T4 consistent (template syntax is fully compatible with T4, module masthead instructions are partially compatible).Their own design template engine, is for the code generator, website template, mail template and other occasions, that is,
language, the user function is responsible for the specific execution logic, these two functions can no doubt only be the stdcall calling convention (Easy language compiler also does not support what other conventions). Here we design our callback function structure, which is represented by pseudo-assembly code:Push user function Address push ecxmov EAX, proxy function address call EaxretThese pseudo-assembly code, if written in easy language, is act
Each stack frame contains a reference to the method that the stack frame belongs to in the run-time pool, which is held to support dynamic connections in the method invocation process (linking).④ method return address When a method starts executing, there are only two ways to exit this method.
The first is that the execution engine encounters a bytecode instruction returned by either method, at which point the return value may be passed to t
