DataGrid控件在数据库编程中的应用

DataGrid控件是最重要的数据感知(Dataaware)控件,它不仅可以把数据库的记录以表格形式显示出来,而且还可以以表格形式编辑数据库的记录。所以,它在数据库编程中应用非常广泛。几乎所有面向对象的编程语言都有这个控件,在最新的ASP.Net编程中还大力提倡使用该控件,因为它可以简化ASP数据库程序的编写。大多数程序员都使用过这个控件,但很多人没有充分发挥它的功能。下面我们结合实际应用来讲述DataGrid控件在数据库编程中的应用。

Winsock编程框架

Microsoft的WindowsSocketsAPI是Windows下的网络应用程序接口，为了适用于Windows下的消息机制和异步的I/O选择操作，WindowsSocketsAPI在功能上扩充了将近20个函数，其中扩充的部分均冠以前缀WSA（WindowsSocketsAsynchronous）,如WSAStartup、WSAClean等，充分体现了Windows的优越性。此外，WindowsSocketsAPI有16位版和32位版两种,16位版是单进程的，32位版则提供了多线程下的安全保护。MicrosoftVisualBasic提供了用于WindowsSockets编程的可用控件——Winsock控件。该控件为用户提供了访问TCP和UDP网络的极其方便…     

处理多个连接的winsock编程

vb中提供了winsock控件以实现通讯功能。利用这个控件我们可以实现基于tcp和udp的远程通讯。下面我们结合一个实例来讲解处理多链接的编程思路。 1.实现的功能 本例程分为两部分,包括一个server和一个client。首先运行server端来监听某个端口,当发现来自client端的连接请求时便接受请求,建立连接,并且利用控件数组,根据客户端的请求创建服务端的连接控件实例来实现一对多的连接。     

单片机与微机串行通信的多语言编程实现

云计算编程模型在机电企业中的应用

HadoopMapReduce环境为云平台编程人员提供了一个复杂的框架，其中，MapReduce是一种编程模型，用于大规模数据集的并行运算。通过MapReduce这个分布式处理框架，不仅能处理大规模数据，而且能将很多繁琐的细节隐藏起来，伸缩性非常好。本文分析7hadoop架构和MapReduce的工作原理，阐述了在云平台上如何执行一个MapReduce作业，介绍了如何编写Mapper和Reducer类以及如何使reporter对象，提出了基于MapReduce架构实现分布式编程的方案。该方案基于Hadoop实现，利用MapReduce架构简化了分布式程序设计。     

A writing program for accounting courses

The author's premise is that communication skills, as well as technical knowledge, are critical elements for success in accounting. Accounting instructors can provide opportunities for students to hone their writing skills while teaching them technical subject matter. Assignments that require research in the profession's literature are particularly valuable for this purpose. Feed-forward and feed-back strategies can simplify the grading task and alert students to their writing deficiencies. Computer-assisted writing and analysis enhance the learning experience by using the technology students will encounter in the work place.     

Your loyalty program is betraying you

Even as loyalty programs are launched left and right, many are being scuttled. How can that be? These days, everyone knows that an old customer retained is worth more than a new customer won. What is so hard about making a simple loyalty program work? Quite a lot, the authors say. The biggest challenges include clarifying business goals, engineering the reward structure, and creating incentives powerful enough to change buying behavior but not so generous that they erode margins. Additionally, companies have to sort out the puzzles of consumer psychology, which can result, for example, in two rewards of equal economic value inspiring very different levels of purchasing. In their research, the authors have discovered patterns in what the successful loyalty programs get right and in how the others fail. Together, their findings constitute a tool kit for designing something rare indeed: a program that won't do you wrong. To begin with, it's important to know exactly what a loyalty program can do. It can keep customers from defecting, induce them to consolidate certain purchases with one seller (in other words, win a greater share of wallet), prompt customers to make additional purchases, yield insight into their behavior and preferences, and turn a profit. A program can meet these objectives in several ways--for instance, by offering rewards (points, say, or frequent-flier miles) divisible enough to provide many redemption opportunities but not so divisible that they fail to lock in customers. Companies striving to generate customer loyalty should avoid five common mistakes: Don't create a new commodity, which can result in price wars and other tit-for-tat competitive moves; don't cater to the disloyal by making rewards easy for just anyone to reap; don't reward purchasing volume over profitability; don't give away the store; and, finally, don't promise what can't be delivered.

Designing a guideline-based utilization management program

Many public and private organizations are developing and publishing clinical guidelines to assist health care providers and patients in making appropriate medical decisions. Unless clinical guidelines are part of a well-designed managed care program, they have little effect on physician practice styles. This article explores integral components of an effective guideline-based utilization management program. Initial evaluation of this program suggests that, as part of a well-designed utilization management program, clinical guidelines can inform patients and physicians, and create appropriate incentives for effective health care delivery.

Auditing program evaluations: The Canadian case

In 1983, the Canadian Auditor General reported to Parliament on the State of program evaluation in the Federal Government. Nineteen departments and agencies were audited and it was found that, since 1978, the government has made progress in implementing program evaluation.This paper describes the audit on which the opinion was based. The background to the audit is presented, followed by a discussion of the audit methodology developed and the audit standards employed. The findings of the audit are summarized along with a brief discussion of the implications of effectiveness auditing for auditing and public administration.
