Run as administrator

[MartinD]

Depending on context, I will need to launch single exe file from Qt application with and without administrator rights on Windows. Is this possible?

@koahnig
The thread you quote is to do with how to run a single instance of a Qt application. How is that connected to the OP's question about ability to run "elevated under Windows"?

Hi
The easy way is just to use a tool.
Like
http://nircmd.nirsoft.net/elevate.html
nircmd elevate notepad.exe C:\Windows\System32\Drivers\etc\HOSTS

and you can just use QProcess to start nircmd.

This assumes i read it right.
From a Qt program, you want to start OTHER app, with and without admin rights

Hmm, again, I (kind of) thought the OP was referring to running a single Qt app elevated & not. But you're interpretation is probably correct :)

@JonB
well the " launch single exe file" made me think App starts other App, but
its not that i would bet beer on it :)

Sorry for confusions. I used this code in my app to elevate privilege when launching an app:

SHELLEXECUTEINFO Shex;
            ZeroMemory( &Shex, sizeof( SHELLEXECUTEINFO ) );
            Shex.cbSize = sizeof( SHELLEXECUTEINFO );
            Shex.fMask = SEE_MASK_FLAG_NO_UI | SEE_MASK_NOCLOSEPROCESS;
            Shex.lpVerb = L"runas";
            Shex.lpFile = f.c_str();
            Shex.lpParameters = args.c_str();
            Shex.nShow = SW_SHOWNORMAL;

            if (!ShellExecuteEx(&Shex)) {
                return;
            }

Hi
Ah, using run as. ( you should have mentioned this from start :)

Im not sure what question is about then.

Are you asking how to use ShellExecuteEx
both as elevated and as not?

As far as i recall, you should replace lpVerb with "open"
to have it NOT ask.
