如题。
小弟刚学vb不久。
昨天试着写个 LAN (S/C) 发送文件的程序,
但写了之后才知道,只可以传送 选定更目录下的文件。
今天早上想把这个问题解决了,但研究到现在还没结果,谁帮下小弟。
写段代码,把 d:\sss (例如) 目录下的所以文件及其嵌套目录和文件,以完整单个路径存到个数组中?(例如, d:\sss\cc.exe ; d:\sss\下一目录\ccs.exe ......)等。

原句 If (FileName <> ".") And (FileName <> "..") Then
改为
If (FileName <> ".") And (FileName <> "..") and UBound(Split(FileName, ".")) > 0 Then
但有很些文件是没有扩展名的,这又如何区别呢?
