Question

delphi 如何获取edit的text中的每个汉字首字母呢？

我需要获取个edit中的text内容里的汉字首字母加在一起组成一个编码赋值给另外一个edit
在网上查询过之前的获取方法，都是一个写出来的GetPYIndexChar函数，用过以后，函数执行时报错，错误主体是'access violation at address 004c4699 in module 'project1.exe',Read of address 00000000. process stopped.
到底是为什么报的错呢？是因为缺少了什么字库还是什么原因呢？
这个函数应该如何写？是否需要汉字字库？
新的问题出来了！经过尝试，书中的源代码是可以直接实现取首字母的功能，最多是有写汉字无法识别，但是我将取首字母的函数考到自己写的代码中用时却会报下面的错误，这是为什么呢？access violation at address 004c4699 in module 'project1.exe',Read of address 00000000. process stopped！
报错时程序停止在‘case WORD(hzchar[1]) shl 8 + WORD(hzchar[2]) of’
不知道WORD(hzchar[1]) shl 8 + WORD(hzchar[2]) 这段代码执行出来的结果是个什么样的呢？有哪位达人有比较全的取首字母的方法呢？很多字都无法取到，很纠结！

追问

我的哥哥哎，这不是一点点长啊！往文本里面一放一看，8KB。鞠躬！先谢谢了！
可以说说这个函数的代码执行机制吗？我希望自己能完全读懂这些代码！

追答

e..其实我也没怎么详细看这个函数。。。我也是在网上找的。。。哈哈哈

你可能是调用了一个无效的参数
