To aiirii:您好，谢谢您以上的代码。由于我是才学Delphi编程不久，上面的代码有些地方我还是看不懂。我试了一下，编译的时候有错误。我用的是Delphi6。其中的 TNetResource和TNetResourceArray，我查了帮助，没找到。是不是Delphi6里面没有这两个类？另外，你的那个程序是针对网络环境的，涉及到网络方面的编程，我真的不懂，很茫然。我只是想得到自己本机的共享信息。您能否把程序简化一下，改成只是针对本机的？谢谢！

要加一句：type TNetResourceArray = ^TNetResource;

我努力的在读这段代码，有个问题：
1、找不到TNetResource的帮助，我很想全面了解一下TNetResource，请问在哪里可以找到？
2、我记得在使用类的对象之前都要Create一下，而上面的代码中在使用NetResource之前并没有Create，请问这是怎么回事？

我已经在帮助中找到，不用麻烦各位了，谢谢：typedef struct _NETRESOURCE {  // nr
    DWORD  dwScope;
    DWORD  dwType;
    DWORD  dwDisplayType;
    DWORD  dwUsage;
    LPTSTR lpLocalName;
    LPTSTR lpRemoteName;
    LPTSTR lpComment;
    LPTSTR lpProvider;
} NETRESOURCE;

To liangqingzhi(老之):
您好，您上面推荐的http://www.piecust.jsol.net/jinjohn/program/delphi/wtj/network/net0009.htm
我已经仔细的看过了，基本上读懂了，真是受益匪浅。不过还是有一个细节上的问题，请解释一下，谢谢：代码中有这样一段：TNetResource(NetworkTypeList.Items[J]^)NetworkTypeList.Items[J]^指的是NetworkTypeList.Items[J]所指向的内存块的内容，这已经是TNetResource类型的了，那这里的TNetResource是什么意思呢？
