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 ? ? ? ? 設(shè)計(jì)時(shí)的自動(dòng)化加快了編碼，并保證所有過(guò)程都用相同的命名規(guī)范和結(jié)構(gòu)來(lái)生成。為了在大型 SQL 項(xiàng)目中盡量提高編碼的效率，作者編寫(xiě)了一系列的設(shè)計(jì)時(shí)（design-time）存儲(chǔ)過(guò)程，用它們來(lái)生成運(yùn)行時(shí)（Run-Time）存儲(chǔ)過(guò)程，并一直在工程中使用。最近，作者更新了其存儲(chǔ)過(guò)程以便使用 SQL Server 2000 的特性，其中包括用戶(hù)定義函數(shù)。本文所及內(nèi)容涵蓋創(chuàng)建并執(zhí)行這些動(dòng)態(tài) T-SQL 腳本以使普通的數(shù)據(jù)庫(kù)存儲(chǔ)過(guò)程編碼自動(dòng)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.

本書(shū)以4個(gè)面向來(lái)表現(xiàn)C++的本質(zhì)：procedural（程序性的）、generic（泛型的）、object-based（個(gè)別對(duì)象的）、object-oriented（面向?qū)ο蟮模１緯?shū)的組織圍繞著一系列逐漸繁復(fù)的程序問(wèn)題，以及用以解決這些問(wèn)題的語(yǔ)言特性。循此方式，你不只學(xué)到C++的函數(shù)和結(jié)構(gòu)，也會(huì)學(xué)習(xí)到它們的設(shè)計(jì)目的和基本原理。 你可以由本書(shū)發(fā)現(xiàn)以下關(guān)鍵主題： ● Generic （泛型）編程風(fēng)格和Standard Template Library(STL) ● Object-based(個(gè)別對(duì)象)編程風(fēng)格和class的設(shè)計(jì) ● Object-oriented(面向?qū)ο?編程風(fēng)格和classes階層體系的設(shè)計(jì) ● Function template 和class template 的設(shè)計(jì)和運(yùn)用 ● Exception handling(異常處理)與執(zhí)行期型別鑒定（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

對(duì)于單個(gè)控件,COMPONET-->INSTALL COMPONENT..-->PAS或DCU文件-->INSTALL。 2.對(duì)于帶*.DPK文件的控件包,FILE-->OPEN(下拉列表框中選*.DPK)-->INSTALL即可。 3.對(duì)于帶*.BPL文件的控件包,INSTALL PACKAGES-->ADD-->BPL文件名即可。 4.如果以上INSTALL按鈕為失效的話(huà),試試COMPILE按鈕。 5.是RUN TIME LIB則在OPTION下的PACKAGES下的RUNTIMEPACKES加之。 如果編譯時(shí)提示文件找不到的話(huà),一般是控件的安裝目錄不在DELPHI的LIB目錄中, 有兩種方法可以解決： 1.反安裝的源文件拷入到DELPHI的LIB目錄下。 2.或者TOOLS-->ENVIRONMENT OPTIONS中把控件源代碼路徑加入到DELPHI的LIB目錄中即可。
