Description: 自己编写的CAD二次开发程序，采用objectARX，功能实现了遍历CAD中所有图层的（也可方便指定图层）的实体的扩展属性（即XData）,利用此程序可方便的提取出你所指定的对象！（本程序在objectARX2002下开发）-prepared by their CAD program, using objectARX. Traversing the realization of all CAD layer (which can also facilitate the designated layer) to the entity Extended Attributes (XDat a), the use of this procedure can be easily extracted your designated target!

Description: 用C51实现的拼音输入法,这是改写的网友 embuffalo、独步上载在www.21ic.com自由发布区的由张凯原作的51上的拼音输入法程序。
原作使用了一个二维数组用以查表，我认为这样比较的浪费空间，而且每个字表的索引地址要手工输入，效率不高。所以我用结构体将其改写了一下。就是大家现在看到的这个。
因为代码比较的大，共有6,000多汉字，这样就得要12,000 byte来存放GB内码，所以也是没办法的 :-(
编译结果约为3000h,因为大部分是索引表，代码优化几乎无效。
在Keil C里仿真芯片选用的是华邦的W77E58，它有32k ROM, 256B on-chip RAM, 1K on-chip SRAM (用DPTR1指针寻址,相当于有1K的片上xdata)。条件有限，没有上片试验，仿真而已。
打算将其移植到AVR上，但CodeAVRC与IAR EC++在结构体、指针的定义使用上似乎与C51不太一样，现在还未搞定。还希望在这方面有经验的网友能给予指导。-C51 with the Pinyin input method, which is rewritten netizens embuffalo. Unrivaled www.21ic.com available in the free publication of the original work by Kai-51 on the Pinyin input method procedures . Appreciate the use of a two-dimensional array for the look-up table, I think this is a waste of space. Each of the characters but the index table to manually input address, efficiency is not high. I use the structure to rewrite a bit. We see now is this. Because the code comparison, a total of 6, more than 000 Chinese characters, this must be 12, byte to store 000 GB code, is not the way to compile results :-( about 3000h. because most of the index table. Code Optimization almost ineffective. Keil in the C simulation uses the chip in W77E58 Winbond, It has 32 k ROM 256B on-chip RAM, 1K on-chi
