没错!~就三仙大大说的~动态去生成处理连线的物件
比方说你是用Socket去实作连线 就先建一个作监听连线用 一旦有连线进来就LOAD一个新的SOCKET 然后将倾听到的连线转交给新生成的去作处理 然后原来的SOCKET就释放连线继续倾听其他连线 大致上就是 在Form_Load的时候 iWinsocket(0).Protocol = sckTCPProtocol '指定使用TCP协定(比较省事) iWinsocket(0).LocalPort = 9999 '指定Server的请听Port iWinsocket(0).Listen 在iWinsock_ConnectionRequest的时候 使用ReDim Preserve 扩大阵列 (Preserve 是可以保留原阵列资料新增扩大的部分) Load新的iWinsock(counter) 然后iWinsock(counter).Accept requestID '将Listen到的连线转交给其他socket x0

Listen的Socket最好固定在一个index(建议啦)
然后连进来之后的要转交给其他port作处理 不然1001已经被先前连进来的占住了当然没办法再Listen 还有就是最好可以在From_Unload那里加个socket.Close 这样表单关掉的时候才能确保port有释放掉 还有就是建议PORT从1024之后开始用吧!~ 已知标准PORT http://www.chu.edu.tw/~chunpo/solaris/tech/docs/port.html 尽量避开常用的标准PORT 挑一段空的来用 netstat -ano 指令可以查查现在本机哪些被用了 x0

下面是引用overing于2008-09-20 11:33发表的 : 1.所以不同的电脑连进来要用不同的PORT了喔?? 就是说对方使用的都是PORT 1024 而我这边要都不同是吗?? 每一个人连进来我的PORT都要设定不同吗??(如:第1个为1024.第2为1025.....以此类堆) 2.新增后的Winsock元件不要用的该怎么移除?? x0

下面是引用w791212w于2008-09-20 15:55发表的 : 1.没错!~  把port比喻作港口好了Server国家要同时跟其他Client国家进行贸易(资料交换) Client们只须要用一个自己有空闲的港口即可 而Server要"同时"跟各国贸易当然要为每一个国家设立一个专属的入港(port) 除非你不是"同时"要跟各个Client作贸易... 通常Server国会开设一个固定的"入港申请处" (固定的port) 这样每个Client国只需要记住入港申请处的port即可 而不必每次要贸易就须要询问一次Server国家他该从哪个port进入 当有Client连上入港申请处就会配给一个专属的port(将连线转交给其他socket) 而入港申请处就继续恢复到等待下个国家的状态 Java方面的作法是利用ServerSocket.accept()将连线转交给Thread+Socket(Client)的方式 VB的话应该可以在ConnectionRequest的时候将requestID交给不同的socket(Index).Accept来做... 如果你不在乎Client每次执行都须要先向Server询问他该从哪个port进入 或是规划上的Client量本来就不多了 那么你现在的方式就可以了...  2.没有要用(已经Close)的socket有两种方式处理 * 留着给之后的连线用 * 使用 Unload 将之卸载 留着的好处是可以让下次不用在建立新的socket 不过要自己稍微写一下分配socket的演算法 Unload掉是对资源使用量比较健康(?)  不过也是得考虑一下index的排列方式 不然Server开久一点idx一直+++下去也会暴 x0
