本教程舉例說明了如何使用 ADO 編程模型對數(shù)據(jù)源進行查詢及更新。教程首先講述了完成此項任務(wù)的必要步驟,然后分別通過 Microsoft Visual Basic、以 VC++ Extensions 為特征的 Microsoft Visual C++、Microsoft Visual Basic、Scripting Edition 和以 ADO for Windows Foundation Classes (ADO/WFC) 為特征的 Microsoft Visual J++ 進行更為具體的說明。

Lotus Notes開發(fā)用的在線DHTML編輯器,基于Active X control 1. This rich text editor is based on the editor used in an older sandbox posting I found. The majority of this code was NOT written by me. Credit goes to someone at Lotus (I think) for the original code. I only extended the base code to add more features, such as cut/copy/paste and adding tables. 2. This editor is based on an Active X control, so it will only work in Internet Explorer. I tested this in IE 5.5, but I think it should would in IE 5.x The Active X control is marked "safe for scripting" and should not trigger a warning from your browser about unsafe content.

uCOSII只提供了操作系統(tǒng)內(nèi)核,用戶要自己添加文件處理、人機界面、網(wǎng)絡(luò)接口等重要部分。其中Shell(人機界面)提供了人與機器交互的界面,是機器服務(wù)于人的體現(xiàn),是系統(tǒng)必不可少的重要組成部分?,F(xiàn)代的很多OS如UNIX、DOS、VxWorks都提供了友好的命令行界面。Windows更是提供了GUI。大部分人認(rèn)識OS都是從這里開始的。 由于Skyeye下的仿真串口USART已經(jīng)實現(xiàn)了中斷方式的接收(實際是從鍵盤接收輸入),而且串口輸出(實際上是輸出到終端屏幕)也已經(jīng)實現(xiàn),所以實現(xiàn)一個類似DOS或Bash的簡化版Shell并不困難。其本質(zhì)思想就是:Shell作為一個uC/OSII下的任務(wù),接收用戶輸入的字符,存儲到緩沖區(qū),并回顯在屏幕上,以回車鍵為用戶輸入的結(jié)束信號,隨后解析用戶輸入的命令名稱、參數(shù),調(diào)用相應(yīng)的命令函數(shù)。一直到這個命令函數(shù)運行返回,才繼續(xù)Shell的人機交互界面。Shell作為一個任務(wù)工作于內(nèi)核之外,占用一個任務(wù)號。

Introduction Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.

無論你是新手還是老手,或是使用其他語言的程序員,我能肯定你能在此書用受益。而本書除了介紹BASH的知識之外,也有許多有用的關(guān)于Linux/UNIX的知識和其他shell的介紹。

ccache 是一個快速的編譯器緩存。當(dāng)您編譯一個程序的時候,它會緩存中間的結(jié)果。這樣,不論什么時候您重新編譯同一個程序,編譯所需要得時間將被大大縮短。對于普通的編譯來說,這可以提高編譯速度5到10倍。 這個想法,來自 Erik Thiele 用bash寫的 compilercache 。只不過,ccache用C再實現(xiàn)了一遍。但比前者性能高許多,也有更多的特性。 (注:Linux下運行)

用純C語言編寫的一個Linux下的Shell,包含tch和bash的基本功能(包含重定向和后臺運行),暫時不支持管道。已經(jīng)在cygwin和Ubantu 7.10下測試通過。 主要包含: makefile 編譯生成myshell可執(zhí)行文件 myshell.c 主函數(shù)(涉及程序入口) utility.c 所有功能函數(shù)(將近1000行) myshell.h(包含宏定義、結(jié)構(gòu)體聲明、庫函數(shù)的頭文件,及utility.c中的所有函數(shù)的聲明) readme 用戶手冊(當(dāng)用戶在myshell里輸入help <command> 時,輸出<command>的使用說明)

The many variants of the Unix operating system require use of a mode of thought that s significantly different from the one that s required by simpler operating systems. Think Unix introduces readers to important fundamental and intermediate Unix commands and, in the process, inculcates them in the Unix way of thinking. It s a worthy goal in a world with more Linux users than ever, and author Jon Lasser accomplishes it. He s both a capable writer and a knowledgeable user of Unix shell commands. Lasser uses bash under Red Hat Linux in most examples--which usually apply equally well to other Unix variants--and makes asides about other shells and environments, as needed.
