HTML 4.01 supports the ISO 8859-1 (Latin-1) character set.The lower part of the Iso-8859-1 (code from 1 to 127) is the original 7-bit ASCII.The higher parts of Iso-8859-1 (code from 160 to 255) all have entity names.Most of these symbols can be used without an entity referen
Map operation Tools, most of the arcengine have ready-made, but these tools are not easy to use, such as the hint and name are in English, map operation without right button, can not and vs provided the tool bar control or Third-party toolbar control integration, or to achieve more flexible and convenient.
Let's start with the simplest zoom tool to implement the common tools for map manipulation.

The Java servlet, as the preferred server-side data processing technology, is rapidly replacing CGI scripts. One of the advantages of servlet beyond CGI is that not only can multiple requests share common resources, but it can also preserve persistent data between different user requests. This paper introduces a practical technique to give full play to this feature, that is, the database connection pool.
The significance of realizing connection pool

Imagine a 5-tuple r= (X,Y,Z,A,B), which is indexed, for a data pair.
Set R={r}, it forms a multi-indexed data table, which is well designed and implemented in a database system.
If we use the Boost Multi_index_container component, how to design it. The

The array is very important in the JS application, many places have used the array to store the data. Today summarize a small problem, but it is easy to forget the little knowledge points.
Requirement: Store the odd number between 1-100 in the array.
Analysis:
Suppose an array of arrays, looping to determine the initial value of Var i=1.
The first way to think about it should be that we judge the I, then pu
