For my C# app, I don’t want to always prompt for elevation on application start, but if they choose an output path that is UAC protected then I need to request elevation.
So, how do I check if a path is UAC protected and then how do I request elevation mid-execution?
The best way to detect if they are unable to perform an action is to attempt it and catch the
UnauthorizedAccessException.However as @DannySmurf correctly points out you can only elevate a COM object or separate process.
There is a demonstration application within the Windows SDK Cross Technology Samples called UAC Demo. This demonstration application shows a method of executing actions with an elevated process. It also demonstrates how to find out if a user is currently an administrator.
