以前发布过一个VB解压缩RAR文档的示例,有很多网友提示出错，后来才发现是 UnRar.dll版本太旧的缘故。现在重新发布一个使用 UnRar.dll进行解压缩、压缩文件测试及注释信息提取等功能的源代码。这个 UnRar.dll目前为最新版，版本是 3.80.2.166，可以向下兼容识别所有Winrar格式的压缩文件。这个示例就是利用这个动态链接库进行的一些操作，但目前还没有压缩文件的功能，里面的dll函数接口还需要进一步的解析和查找资料，官方好像也没有提供，希望有知道的网友也可以提供一下。更希望感兴趣的网友继续进行挖掘和开发。

源代码附有详细的注释和文档说明。-　　

Previously released a VB example of extracting RAR documents, there are many tips User error, was later found to be too old version of UnRar.dll reasons. Now re-released a decompressed using UnRar.dll, compressed files, and notes information extraction test functions such as source code.

This example is the use of a dynamic link library for some of the operations, but there is no compressed file function inside the dll function interface also need further analysis and finding information, the official did not seem to offer hope to know User can also provide about. I also hope to continue excavation interested netizens and development.
