PB10如何获得本操作系统的IP地址

怎样使用PB10如何获得本操作系统的IP地址

IP地址与操作系统无关吧

应当叫本机的IP地址
使用Winsock控件，用Winsock1.LocalIP即可得到本机的IP地址

下面是使用API的

window2000 sp4, pb9 下通不过，提示gethost参数错误，何故？

达人帮忙解决一下......

[quote]在使用上述代码时要定义一个structure s_wsadata [/quote:58c06017b2]

注意上面的这句话。
s_wsadata可能是个数据结构,你查看一下你的PBL里是否有这个数据结构.

需要新建立pbw和pbt然后migrate才可以正常使用.
migrate的时候还要将另外一个pbl包含进来!

What is next

You'll decide that your previous conclusions were wrong and change ways?
