如何保证智能客户端应用的数据安全-how smart client application data security

INDUCTION MOTOR RUN (Currents and speed as state variables) The motor is running at a specified load. After reaching steady state in an initialization first run, the initial conditions are established for a second run in which the load is pulsating. The dynamic equations are expressed in canonical first-order matrix form adopting currents and speed as state variables, and are solved using ODE45. The user has the choice of selecting one of three common (dq) reference frames: STATOR, ROTOR or SYNCHRONOUS. The torque, speed,and current responses are plotted. -INDUCTION MOTOR RUN (Currents and speed as state variables) The motor is running at a specified load.

数据库应用，在许多软件系统中经常用到，是开发中大型系统不可缺少的辅助。但如果对数据库资源没有很好地管理(如：没有及时回收数据库的游标(ResultSet)、Statement、连接 (Connection)等资源)，往往会直接导致系统的稳定。这类不稳定因素，不单单由数据库或者系统本身一方引起，只有系统正式使用后，随着流量、用户的增加，才会逐步显露。 -database applications, in many software systems often used, is developing large systems indispensable aids. But if the right database resources are not well managed (eg : no timely recovery database cursor (ResultSet), the Statement connect (Connection), and other resources), will often lead directly to the stability of this system. Such factors of instability, not only by the database system itself or caused side, the official use only, as the flow of users increases, will gradually revealed.

对数据库进行方便的操作！-the database to facilitate the operation!

这是一个小型的航空公司的管理系统，是用VB6.0编写的，里面使用DAO建立数据库，用ADO对数据库进行操作-This is a small airline management system, is used to prepare the VB6.0, DAO is used to establish a database with ADO operation of the database

一个车辆管理系统 -A vehicle management system

一款ADO处理数据库的软件,例子处理数据库在源码内,对数据处理后对数据进行树状分类,点击后可以在右边看到数据库信息,是某个项目的一部分-ADO a deal with the database software, for example, deal with the database in the source, the treatment of data after the data classification tree, click on the right can see the database information, is a part of the project

这里给出两个 建立ADO连接字符串对话框 的例子。 datalinks.cpp 建立和编辑ADO连接字符串 linktest.cpp 如果只是建立连接字符串，程序还可以这么写。-here is the establishment of two ADO connection string dialog example. Datalinks.cpp create and edit ADO connection string linktest.cpp if only to connect strings, procedures can also write.

vb+access做的办公系统，没有使用sql server 2-vb+ access office systems do not use sql server 2000

SQLite 3.x的一个C++封装类。基于MFC。SQLite是一种高效的嵌入式数据库。-SQLite 3.x a Class C Packaging. Based on the MFC. SQLite is a high-performance embedded database.
