Detect if running as Administrator with or without elevated privileges?

阅读更多关于 Detect if running as Administrator with or without elevated privileges?

I currently have code set up like this: static bool IsAdministrator() { WindowsIdentity identity = WindowsIdentity.GetCurrent(); WindowsPrincipal principal = new WindowsPrincipal(identity); return principal.IsInRole (WindowsBuiltInRole.Administrator); } This works to detect if a user is an administrator or not, but doesn't work if running as an administrator without elevation. (For example in vshost.exe). How can I determine whether or not elevation is [already in force or] possible ?

Request UAC elevation from within a Python script?

阅读更多关于 Request UAC elevation from within a Python script?

问题 I want my Python script to copy files on Vista. When I run it from a normal cmd.exe window, no errors are generated, yet the files are NOT copied. If I run cmd.exe \"as administator\" and then run my script, it works fine. This makes sense since User Account Control (UAC) normally prevents many file system actions. Is there a way I can, from within a Python script, invoke a UAC elevation request (those dialogs that say something like \"such and such app needs admin access, is this OK?\") If
