Regular expressions are used for string processing, form validation, and so on, practical and efficient, but often not too sure to use, so it is always necessary to search the Internet. I've collected some commonly used expressions here for the purposes of my memo. This post will be updated at any time, please continue to pay attention to this site.
Matching regular expressions for Chinese characters: [\U4E00-\U9FA5]
Match Double-byte
A description of the search for wildcard-wildcardYou can search for wildcard characters. There are two ways to specify characters that are commonly used as wildcards:
Use the Escape keyword to define an escape character. In a pattern, the wildcard is interpreted as a normal character when the escape character is placed before a wildcard. For example, to search for a string containing the string 5% anywhere,
vbscript| Function | The left () function of the Chinese character is VBScript, and VBScript considers 1 characters as 1 characters, so the left () does not get the correct character length.
I wrote the following 3 functions to replace Len (), left () and right () in the hope of solving your problem.

4.5.1 annotation character (Annotation)
Two types of annotation characters can be used in Transact-SQL.
The ANSI standard annotation character "--" is used for single-line annotations;
The same as the C language of the program annotation symbol, that is, "/**/". "/*" is used for the beginning of the annotation text, "*/" for the end of the comment text, you can identify multiple lines of text in the program as comments.
4.5.2 operator (Operator)
In the current project, the length of the string is computed and the fixed-length character is truncated, in which the Chinese character is calculated in 2 characters, the number and the letter are calculated in 1 characters, and no ready-made functions can be used to refer to how to get the exact length of a string of characters and letters (asp.net version) Htt

When searching for related technical documents or paper materials on the Internet, you often encounter some traditional documents. How to convert it quickly into simplified characters? Maybe you will use Third-party conversion software, but we only need Word document can be achieved, the following together with small to see how to use it.
The method of operation is simple:
1. Open the Word document that you want to convert.
2. Select the text you w

Title: Given a string, the length of the oldest string with no repeating character is obtained.
Idea: For loop once, time complexity is O (N). The ASCII value of the character is 32~126. Start represents the initial position of the current non-repeating character string, with an initial value of 0, and a positional array of pos[128] that represents the position of the corresponding character at the current position of the for Loop index. If the current character is S[i] (its ASCII value is Cur
