File Copy

[AdrianMorris]

Hello!

I'm trying to copy a file from another computer on the network that I do not
have permission with my current logon details to access.

If I open the folder using the Windows file manager with the path "\\
192.168.2.2\temp" (where temp is a shared directory on server \\192.168.2.2),
windows prompts for a User Name and password of a user who has permission on
that computer to access that directory. If I enter valid details, the folder
is opened and I can copy files from this machine.

How do I do this programmatically in c++ or c#? Standard file open and/or
directory commands do not have the option to enter a valid Username/password
and they just fails with permission denied (understandably).

Regards....Adrian

Try using WindowsIdentity.Impersonate() to impersonate the user
account you want to use to access files, and invoke File.Copy when
impersonated.

Hello Pavel,

Many thanks for your suggestions.

I used the "LogonUser" followed by the "ImpersonateLoggedOnUser" functions
and all is working well.
