一直以来用 AxIcon Workshop 来处理图标，但是 AxIcon Workshop稍微有点问题就是，不支持重复图标过滤，而且，在处理大量图标的时候很容易没有响应！：（
为此，我自己写了一个图标处理工具，可以自动抽取 DLL/EXE/ICL 等文件中的图标，并进行重复图标自动过滤，图标扫描等功能，其中比较困难的是对 ICL 文件的处理，ICL 文件本质上是一个 16 Bit 的 DLL 资源文件，但是在 Windows 2000 下好象没有直接操作它的函数，至少我是不知道，查了 Google 也没查到相关资料，没有办法，只有硬来了，查了 16 Bit 的 EXE 的文件结构资料，结合网上可以找到的一些对16 Bit 的 EXE 的读写代码片段，再经过探索和摸索，终于成功的将从 ICL 中分离出 ICON 。其中的关键代码如下：希望给你有帮助
