发帖数: 920 | 1 There is a public link on the sever, and I need to download multiple files
from that link, such as this
http://www.pjm.com/markets-and-operations/energy/real-time/hist
data/unit-bid.aspx
I can do it manually, this time since there are only 50 files,but further
there will possibly be thousands of similar files.
Any suggestion how to create a macro in complete this task? |
