Web Services Enhancement 3.0

What is Web Services Enhancements? To achieve Web Service interoperability in enterprises, XML Web Service vendors (including Microsoft, IBM, and Verisign) propose new standards, it is used to improve the interoperability of key Web service fields (such as security, message transmission reliability, and attachment sending. To support these new standards, Microsoft released Web Services Enhancements (WSE) 1.0, which includes a group of classes used to implement these new protocols and a group of

Solve Delphi7 built-in UTF-8 encoding conversion Function Bug

Delphi7 and earlier versions of VCL only support ANSI, so... widestring and utf8string (same definition as ansistring) cannot be correctly displayed in VCL The UTF-8 conversion function provided by Delphi7 returns NULL if it encounters a character string that cannot be identified. Use the following conversion function to solve this bug: unit util_utf8; interface uses Windows; type UTF8String = AnsiString; function AnsiToWide(const S: AnsiString): WideString; function WideToUTF8(const

. At the architectural level, we compare some existing service replication middleware with the object replication middleware.The result is that replication middleware in the so system has a lot in common with replication middleware in the distributed object system. Some differences are caused by the granularity of the replicated entity and different transaction models.(2) Existing so replication MiddlewareA) Primary-Backup replication middleware: "Fault Tolerant Web Service"B) active replication

Based on the combination of html5 and nodejs to implement websocket, even if the communication _ node. js

is naturally preferred, second, the node. js event-driven method is very good at maintaining highly concurrent connections with a large number of clients. So we chose NodeJs. The implementation of the server is very simple. First install a nodeJs module named nodejs-websocket, and directly input: npm install nodeJs-websocket in the nodejs command line to install it, then we can start to build the server. Because the nodejs-websocket module is available, we don't need to do much work on our own.

Poj 3693 maximum repetition substring

For the minimum Lexicographic Order condition, I did not think of a very good solution strategy, but the default R [L * I] is in the first loop section, then enumerate the positions of the first character in the first loop section. If the repetition number is equal to Max at this time, record the string. If the repe
