How to use WMI to copy a file from computer A to computer B using unmanaged VC++

Question

I need to have my unmanaged VC++ program able to copy a file from the computer the application is on to one of 100 other computers.

I have administrator access on each computer, so that won't be a problem.

It seems I need to use WMI to do this, but I am having a hard time getting it to work properly by looking at examples in: http://msdn.microsoft.com/en-us/library/windows/desktop/aa394558(v=vs.85).aspx

I am curious of the CopyFile family of functions should work:

http://msdn.microsoft.com/en-us/library/windows/desktop/aa363851(v=vs.85).aspx

This is a console application that doesn't use MFC and isn't using ATL.

Is there a good example of how to do what I am trying to do that will work on WinXP and Windows 7?

Answer 1

The easiest way is probably to start by creating a network connection with WNetAddConnection2, then copy the file with something like CopyFile or CopyFileEx. When you're done, it would be courteous to use WNetCancelConnection2 to remove the network connection.

Answer 2

The only WMI class designed to manipulate files is the CIM_DataFile class, they include a set of methods (Copy, CopyEx) to copy files but only works in the target machine, this means which you cannot copy a file from one machine to another using the WMI (at least which you use a network drive or shared).
