Whether one supports peace or not should not be judged by a particular country or on the basis of a particular meeting. China sincerely hopes that a peace conference will not turn into a platform used to create bloc confrontation. Not attending it does not mean not supporting peace. For cert...

Regular expressions provide a unique way to search a volume of text for a particular subset of characters within that text. Instead of looking for an exact character match as you would do with a function likestrfind, regular expressions give you the ability to look for a particularpatternof ch...
Function Example \ Defines an escape character. It converts a special or common character next to it into a common character. \* matches *. ^ Matches the start of the string. ^10 matches 10.10.10.1 instead of 172.16.1.1. $ Matches the end of the string. 1$ matches 10.10.10.1 ins...
The RegularExpressionValidator control checks whether the value of an input control matches a pattern defined by a regular expression. This type of validation allows you to check for predictable sequences of characters, such as those in email addresses, telephone numbers, and postal codes....

The search() function takes the pattern and text to scan, and returns a Match object when the pattern is found. If the pattern is not found, search() returns None. Each Match object holds information about the nature of the match, including the original input string, the regular expression...
Alternatively, the character literals 'true' or 'false' (case-sensitive), The default value is 'false'. The valid argument types for arg1, arg2 are CHAR, CLNT, LANG, NUMC, CUKY, UNIT, DATS, TIMS, and SSTRING. If an argument of a string function has the null value, the result of ...
