Giving write permission to Users group in Vista?

IS there any API that can give 'User开发者_StackOverflows' write permission to a file in Vista?

You would want to modify the ACL of the file. For example see related Win32 APIs to: SetNamedSecurityInfo.

If all of that seems a little frightening to you, you can consider simply running a process that calls: cacls

For example giving a directory everyone permission:

cacls "directoryPathHere" /e /t /g Everyone:f

For more information on the command line parameters type in a command prompt:

cacls /?
