汉字拼音的首字符，可以在数据库中作为某一关键字段（如：商品的名称、客户单位的名称等）的辅助查询字段来简化查询过程中的输入问题。也就是说，用户只要输入需要查找的汉字拼音的首字符，就能很快定位到要查找的记录，当要查找的字数在4、5个以上时，其重码率还是很低的。提起将汉字转化为拼音，大家可能以为这是一个复杂的问题，比如将拼音输入法的码表文件进行逆转换，再根据汉字来查询拼音等等。其实我们需要的只是汉字拼音的首字符，其实用 VB6 实现这一功能问题远没有这样复杂。下面把用 VB6 实现这一功能的方法介绍如下。-Pinyin character, as a key field (such as: the product name, the name of the client units, etc.), auxiliary database query field, enter the query process to simplify the problem. That is, the user can enter the first character of the need to find Pinyin, can quickly locate the records you want to find, when you want to find the number of words in more than four or five, the heavy bit rate is still very low. Lift the Chinese characters into pinyin, we may think that this is a complex issue, such as Pinyin input method of inverse conversion code table file, characters to query Pinyin. In fact, we need only the first character of the Pinyin fact, using VB6 to achieve this function far from such a complex problem. The following method to achieve this function with VB6 described below.
