我正在使用下面的代码从文本框中输入一个字符串，然后转换为大写字母，除了像（the，and，an，as，to或on等）之类的单词等。
问题＃1：我希望字符串的第一个单词始终大写，无论单词是什么。
问题＃2：当字符串重新组合在一起时，字间距不正确。
xText = queryForHTML
xTextSplit = split(xText, " ")
for each item in xTextSplit
xWord = item
if lcase(item) = "the" or lcase(item) = "and" or lcase(item) = "an" or lcase(item) = "as" or lcase(item) = "to" or lcase(item) = "is" or lcase(item) = "on" then
xWord = lcase(item)
end if
xCompleteWord = xCompleteWord & " " & xWord
next
queryForHTML = xCompleteWord

基本思想是使用匹配任何序列的正则表达式＆＃34; word＆＃34;字符（[a-zA-Z0-9]），对于每个序列，调用一个函数，它接收字符串匹配的参数，包含单词的捕获组，字符串中找到它的位置以及完整的源字符串。
如果单词位于0位，则为大写。如果这个词是＆＃34;噪音＆＃34;单词，它是小写的，否则，这个词是大写的。

以下代码基于GetStringTypeW() Win32 API函数，该函数提供有关字符串中字符的信息。你只担心可以是大写或小写的字符。您的代码的问题在于它仅适用于空格分解单词的最简单情况。但话语可以通过标点符号来分解。并且有许多Unicode字符没有＆＃34;大写＆＃34;和＆＃34;小写＆＃34;。
我没有编写这个无聊，容易出错的代码来执行此操作，而是利用了GetStringTypeW（）。我遍历数组中的每个元素，其中每个元素对应于相同位置的字符串中的字符。我有一个标志bInWord，用于存储当前位置是否在单词内。如果我们点击大写或小写字符，并且没有设置，我们设置它，并将当前位置保存为单词的开头。另外，如果我们遇到一个大写字符，并且我们已经知道我们在一个单词中，那么我们在那里然后通过写入返回的字符串使字符小写。
当我们点击非字母字符或到达字符串的末尾并设置bInWord时，我们会将最后一个字与＆＃34;非正确字符＆＃34;的列表进行比较。话。如果我们匹配，并且第一个字符是大写，那么我们用小写字符覆盖该字符。如果我们不匹配，并且第一个字符是小写的，我们会用大写字符覆盖该字符。
