My share add-in application have a automatic detect User Acount Control (UAC) state (On/Off) function. I use this method:

static internal bool IsAdmin()
{

WindowsIdentity id = WindowsIdentity.GetCurrent();
WindowsPrincipal p = new WindowsPrincipal(id);
return p.IsInRole(WindowsBuiltInRole.Administrator);
}
Return true if UAc is Disable
Return false if UAC is Enable
when i use Word 2007 on Vista Ultimate, the received result of IsAdmin() method is always correct
But when i use Word 2003 on Windows Vista Ultimate, IsAdmin() always return "true" eventhough I still enable UAC
Help me resolve this problem!!!

Hi Hungnn,

As far as I know, your code sinppet is just for checking whether the current application is running as Administrator, but not checking whether UAC is ON/OFF.

If you enable UAC, the application will run in different levels :User/Adiministrator, you can use Run as Administrator elevating User to Adiministrator, so you will get true or false. But if you disable UAC, it will return one state: User or Administrator.

If you want to check for UAC by application, as far as I know, UAC by design is difficult to check for. We don’t want applications checking for it and acting differently. We want applications to act properly with UAC turned on.

And I highly suggest you post your question in appropriate forum, and you will get better answer.

Best Regards,
Nancy
