汉字转换为拼音的代码

'***************************************************************************

'* MODULE NAME: HzToPy

'* AUTHOR & DATE: tt.t

'* 03 Apirl 2007

'* DESCRIPTION: 将中文字符串转换为拼音，就这些～

'* 有汉字得到拼音其实并不是我很关心的一个问题，只是发现已经公开

'* 的方法有很大的缺陷，但WORD却做得很好，因此才尝试解决这个问题。

'* 过程比我预期的要曲折的多，主要是VBA实在是一种很受限制的语言。

'* 不过好在有Google和Olldbg，难题也仅仅是如何找到绕过限制的途径，

'* 终于在5个小时内搞定了一切～

'* 时间比我预计的长了很多，因为我实在是不了解VBA，也不很熟悉OLE:"(

'* 不过好在一切都解决了～～终于从VBA小白成长了一些。

'* 其实VBA也是很强大的～

'*

'* Theory： 废话了好多还是说说原理吧，虽然不是每个人都很关心～

'* WORD的拼音向导能够将汉字转成拼音全是倚仗微软拼音的帮助，

'* 微软拼音2.0以上版本都提供了汉字到拼音的转换功能。

'* 微软拼音类中的IFELanguage接口具体实现了转换功能

'* 不过中没有提供IDispatch接口，VBA的CreateObject不支持

'* 调用这样的类，因此我们只好手工调用。CoCreateInstance可以创建类

'* 并获取IFELanguage接口，但我们无法直接调用，因为VBA不知道如何调用

'* IFELanguage接口的Method。这里困扰了我好久，原本希望能向其他语言那样

'* 声明接口结构，但VBA并不支持。万般无奈下只好在OLE相关DLL中寻找，期待能

'* 找到代理函数简介调用接口的Method。呵呵～功夫不负苦心人终于在OLEAUT32中

'* 找到了DispCallfunc。Google了一下，果然是我需要的。接口知道了，如何调用也

'* 清楚了，剩下的问题就是如何取得转换后的结果。phResult会将

'* 转换的结果存在一个叫做tagMORRSLT的结构中，并返回指向tagMORRSLT的指针。

'* 新问题又来了，VBA不支持指针...sigh，为什么其他语言很容易实现的功能VBA用起来

'* 就这么烦呢～幸好VBA读取内存的限制也好突破，只需调用ntdll的RtlMoveMemory。

'* 好了～一切限制都已解除，HzToPy终于正常工作了～～

'* 说起来一切顺理成章，可是寻找解决方法的过程真的很痛苦，不过VBA经验值大涨也算有所收获。

'* 下面就让代码来说话吧。

'*

'* Memo: 改成类了，加入了拼音间加入分隔符和去掉注音的功能，请参照“模

1

块1”中的例子，用起来很简单：）

'* 更正了一个错误，redim时vba数组默认起始搞错了
