uac

I need to use the systemRoot feature of the Preferences API, but it fails due to lack of permissions on Windows if UAC is on. I'm trying to find the technical details of popping the UAC prompt and elevating my permissions to allow the systemRoot updates to succeed. Stephen C According the accepted answer to this SO question , you cannot change the UAC permissions of a running process. According to the answers to this SO question , possible ways to launch a process with elevated permissions are: create a wrapper to launch the JVM (with the appropriate arguments!) with a windows manifest that

I have an application which needs the UAC elevation. I have the code which lets me give that but the application opens twice.. which is the issue.. so here is the code in Form1: public Form1() { InitializeComponent(); WindowsPrincipal pricipal = new WindowsPrincipal(WindowsIdentity.GetCurrent()); bool hasAdministrativeRight = pricipal.IsInRole(WindowsBuiltInRole.Administrator); if (!hasAdministrativeRight) { ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.UseShellExecute = true; startInfo.WorkingDirectory = Environment.CurrentDirectory; startInfo.FileName = Application

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? Adrian Clark 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

I have a program that only requires elevation to Admin on very rare occasions so I do not want to set-up my manifest to require permanent elevation. How can I Programmatically request elevation only when I need it? I am using C# WindowsPrincipal pricipal = new WindowsPrincipal(WindowsIdentity.GetCurrent()); bool hasAdministrativeRight = pricipal.IsInRole(WindowsBuiltInRole.Administrator); if (!hasAdministrativeRight) { RunElevated(Application.ExecutablePath); this.Close(); Application.Exit(); } private static bool RunElevated(string fileName) { //MessageBox.Show("Run: " + fileName);
