Question

RequestedExecutionLevel not worked

Andreas Mazatis 131

I am writing an application that any user, admin or not, can access. At startup an update of the program files under c:\Program files should be performed with Robocopy. Robocopy starts but the permission check does not allow access. I have already experimented process.StartInfo.Verb = "runas"; and in the manifest requestedExecutionLevel. Unfortunately all without success. Is there a way that any user can run this and get access to c:\Program Files via Robocopy?

In order for the runas verb to be effective you must also specify UseShellExecute=true

If I do that, this message comes:

If you cannot use ShellExecute then the your process must already be running with elevated privileges.

A workaround may be to use ShellExecute start a command processor (cmd.exe) with elevated privileges and pass a command line to it that runs robocopy and redirects its output to files. Afterwards you can read the files that robocopy created.

CSMeh.exe just writes its arguments to standard output and error output

namespace CSMeh  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            foreach (string s in args)  
            {  
                Console.Error.WriteLine("Written to error stream : " + s);  
                Console.WriteLine("Written to output stream : " + s);  
            }  
        }  
    }  
}

Use elevated cmd.exe to run CSMeh and redirect its output

            try  
            {  
                Process p = new Process();  
                p.StartInfo.FileName = "cmd";  
                p.StartInfo.UseShellExecute = true;  
                p.StartInfo.Verb = "runas";  
                p.StartInfo.Arguments = "/C C:\\Users\\RLWA32\\source\\repos\\Rlwa32\\RedirMeh\\Debug\\CSMeh.exe parm1 parm2 > C:\\Users\\RLWA32\\Documents\\both.txt 2>&1";  
  
                p.Start();  
                p.WaitForExit();  
            }  
            catch (Exception ex)  
            {  
                Console.Write(ex.Message);  
            }

Can you use any of the logging options for robocopy to achieve your objective instead of redirecting output?
