在用pb开发信息管理系统时，为了安全期间，我们希望记录每个登录用户的信息，并生成日志，其中最重要的是知道是哪个机器运行程序的？这样，只要获取运行程序的机器ip问题就解决了，然而，pb中没有象delphi 中有现成的函数可以很方便的获的机器的ip，我们只好利用外部函数来实现了。-used pb in the development of information management systems, for the sake of safety, We hope to record each user's login information, and generates log, One of the most important is to know which machine is operational procedures? Thus, as long as the operational procedures for access to the machine ip issue will be solved, but pb not like delphi are ready function can be very convenient machines ip, we can only use external function realized.
