Alkaline batteries are convenient because they’re easy tofi nd and relatively inexpensive, making them the powersource of choice for portable instruments and devicesused for outdoor recreation. Their long shelf life alsomakes them an excellent choice for emergency equipmentthat may see infrequent use but must be ready to go on amoment’s notice. It is important that the DC/DC convertersin portable devices operate over the widest possiblebattery voltage range to extend battery run time, and thussave the user from frequent battery replacement.

摘要 ? ? ? ? 设计时的自动化加快了编码，并保证所有过程都用相同的命名规范和结构来生成。为了在大型 SQL 项目中尽量提高编码的效率，作者编写了一系列的设计时（design-time）存储过程，用它们来生成运行时（Run-Time）存储过程，并一直在工程中使用。最近，作者更新了其存储过程以便使用 SQL Server 2000 的特性，其中包括用户定义函数。本文所及内容涵盖创建并执行这些动态 T-SQL 脚本以使普通的数据库存储过程编码自动化。

The Gray Watson debugging malloc library is C source code for a drop in replacement for the system malloc & other memory manage ment routines. What is unique about this library is that it contains a number of powerful debugging facilities including very comprehensive heap testing and ex- cellent Run-Time debugging information.

The project KEIL_IODemo shows how to use memory allocation routines (malloc) and char I/O (printf, scanf) via a serial interface with the Keil ARM toolchain. The I/O functions are adapted for the Analog Devices ADuC7000 series using the SERIAL.C module. The example also shows the efficiency of the Keil CA ARM Compiler Run-Time library which is tuned for single chip systems.

本书以4个面向来表现C++的本质：procedural（程序性的）、generic（泛型的）、object-based（个别对象的）、object-oriented（面向对象的）。本书的组织围绕着一系列逐渐繁复的程序问题，以及用以解决这些问题的语言特性。循此方式，你不只学到C++的函数和结构，也会学习到它们的设计目的和基本原理。 你可以由本书发现以下关键主题： ● Generic （泛型）编程风格和Standard Template Library(STL) ● Object-based(个别对象)编程风格和class的设计 ● Object-oriented(面向对象)编程风格和classes阶层体系的设计 ● Function template 和class template 的设计和运用 ● Exception handling(异常处理)与执行期型别鉴定（Run-Time Type Identification）

Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices at startup or when they are plugged in at run time. These devices are broken into various device classes. Each device class defines the common behavior and protocols for devices that serve similar functions. Some examples of USB device classes are shown in the following table

对于单个控件,COMPONET-->INSTALL COMPONENT..-->PAS或DCU文件-->INSTALL。 2.对于带*.DPK文件的控件包,FILE-->OPEN(下拉列表框中选*.DPK)-->INSTALL即可。 3.对于带*.BPL文件的控件包,INSTALL PACKAGES-->ADD-->BPL文件名即可。 4.如果以上INSTALL按钮为失效的话,试试COMPILE按钮。 5.是RUN TIME LIB则在OPTION下的PACKAGES下的RUNTIMEPACKES加之。 如果编译时提示文件找不到的话,一般是控件的安装目录不在DELPHI的LIB目录中, 有两种方法可以解决： 1.反安装的源文件拷入到DELPHI的LIB目录下。 2.或者TOOLS-->ENVIRONMENT OPTIONS中把控件源代码路径加入到DELPHI的LIB目录中即可。
