介绍(Introduction)

作为网站管理员,我在网络上进行了大量研究.这需要许多不同的工具来管理链接,内容和域(当然,我最喜欢的是<先锋报告>;).搜索引擎研究是一项重要任务.它涉及将一个链接列表与另一个不同列表进行比较.(As a webmaster, I do a lot of research on the web. This requires many different tools to manage links, content, and domains (of course, my favorite is Pioneer Report ;)). One important task is search engine research. It involves comparing one list of links with another, different list.)

很容易找到列出或列出列表的软件.但是,如果要比较两个列表怎么办？如果您想知道每个列表的共同要素是什么？如何知道一个列表中有什么而不​​是另一个列表,并消除所有重复项呢？(It is easy to find software which makes a list or takes a list. But, what if you want to compare two lists? What if you want to know what are the common elements to each list? How about knowing what is in one list but not in another, and eliminating all the duplicates?)

这段代码解决了这个问题.(This code solves this problem.)

背景(Background)

网络上有很多使用数据列表的工具.这包括股票市场研究,网站管理员工具,政府数据,产品信息等.作为网站管理员,我使用许多产生或使用列表的工具.但是,这些工具都不会让您比较它们产生或使用的不同列表.(There are a lot of tools on the web which use lists of data. This includes stock market research, webmaster tools, government data, product info, etc. As a webmaster, I use many tools which produce or use lists. However, none of these tools let you compare the different lists they produce, or use.)

为了解决比较列表的问题,我决定编写以下代码.(To get around the problem of comparing lists, I decided to write the following code.)

使用代码(Using the Code)

除了许多用户界面命令之外,还有三种用于比较列表的基本例程.他们是:(Besides a lot of user interface commands, there are three basic routines for comparing lists. They are:)

• CString AnotB(CString&)
• CString BnotA(CString&)
• void OnResultsAandB() 在比较过程中,例程将所有结果按字母顺序排列.因此,将结果写入"结果"窗口后,它是按字母顺序排列的.(In the process of comparing, the routines alphabetize all results. So, once the result is written in the Results window, it is in alphabetical order.)

这就是(This is what the) AnotB 例程代码如下:(routine code looks like:)

int CBigFinderDlg::AnotB(CString& sBody) 
{
    std::map<CSTRING, int>::iterator <CODE>it;

    int nResultsCount = 0;

    for (it = m_aMap.begin(); it != m_aMap.end(); it++)
    {
        std::map<cstring, />::iterator itb;

        BOOL bSkip = false;

        for (itb = m_bMap.begin(); itb != m_bMap.end(); itb++)
        {
            if (it->first == itb->first)
            {
                bSkip = true;
                break;
            }
        }

        if (!bSkip)
        {
            if (nResultsCount > 0)
                sBody += "\r\n";

            sBody += it->first;

            nResultsCount++;
        }
    }

    return nResultsCount;
}

兴趣点(Points of Interest)

在比较例程之外,大多数代码只是UI内容.但是,它确实使使用该软件进行比较变得更加容易.(Outside of the comparison routines, most of the code is just UI stuff. However, it does make it easier to use the software to do comparisons.)

有很多方法可以改进此工具,我将添加更多功能.要添加的一些新功能是从文件加载列表.此外,对于大型列表,应用程序将锁定直到完成.通过添加线程,如果花费太长时间,它可以使您停止应用程序.(There are many ways to improve this tool and I will add a lot more features. A few new features to add would be loading lists from a file. Also, for large lists, the app locks until it finishes. By adding threads, it lets you stop the app if it is taking too long.)

但是,总的来说,它似乎是一个非常有用的小工具.我期待在整个地方使用它.(However, all in all, it appears to be a very useful little tool. I look forward to using this all over the place.)
