本文论述了WinSock 编,以及在PB 中编写TCP/ IP 程序的实现方法同时指出了PB 通过使用win2
dows 下的sockets 接口及通过访问WinSock. DL 中的函数实现网络通信的原理。并论述了网络消息发送的底层工
作原理,以及实现在企业局域网内点对点的信息转发或点对多的信息广播的方法。
This paper introduces the WinSock program and the way of realization of TCP/ IP program2
ming under the situation of PB. It explains the principle of PB network communication realization through
using the sockets connection under windows and visiting the function in Winsock.DL. The substrate work2
ing principle of network message transmitting and the realization of point- point message sending within
local network or point to multi- points message broadcasting methods are discussed. (2009-02-24, PowerBuilder, 82KB, 下载13次)
