各位大侠，在本机通过GetDiskFreeSpace可以获得本机磁盘容量，

是否要对lpRootPathName进行修改啊
怎么修改？（假如你已经知道了IP地址了）

如果硬盘共享，依次盘符会是h:,k:,l:
sdrive="h:\"即可
如果有driver控件，会自动列出所有的盘符
sDrive = Left$(DrvSelect.Drive, 1)
sDrive = sDrive & ":\"

各位，我想知道怎么给sdrive赋值啊，如果赋值为“c:\”，那是在访问本机的c盘剩余空间啊，如果要获得局域网中其它机器的c盘剩余空间，又该怎么做啊？顺便说一下，机器硬盘已经共享了。
麻烦大家详细告知一下啊！！

将机器的硬盘共享即可
