Re: WMI CopyFolder functionality in C++

Hi SSN,

Can you give us a high-level overview of what the code actually does? Like step by step?

Hi,
Can anybody point or tell me how to copy a local folder to a remote
machine? I can do wmi connections, I just need the stuff about setting
the parameter properly and the copy folder call. I need it for c++.

Thanks in advance.
