在c++builder中获取mac地址的源码，使用iphlpapi库，以前的通过netbios,com,以及snmp的方法都有局限性，此程序是最好的获取mac地址的方法。在bcb6中编译通过。注意(需要在project->option->Directories/Conditionals->Library Path中增加iphelpapi.lib的路径，如：C:\\Program Files\\Borland\\CBuilder6\\Lib\\Psdk）-acquired mac addresses of the source, the use of iphlpapi basement, before the adoption netbios, com, and snmp methods have limitations, this procedure is the best mac addresses of the access method. In bcb6 compiled through. Attention (in project-gt; Option-gt; Directories / Conditionals - gt; Library Path increase iphelpapi.lib path, such as : C : \\ Program Files \\ Borland \\ CBuilder6 \\ Lib \\ Psdk)
