How to start/stop windows service using Qt? - qt

Question

Lets imagine situation: I have running windows service named "Test". Now I want to stop or start (if it's stopped) this service using Qt app.
How can I do it?
Note:
I don't want to call cmd and use "net start" and "net stop" commands!

Answer 1

You could use the corresponding Qt Solution https://github.com/qtproject/qt-solutions/tree/master/qtservice
Then you can do something like:
QtServiceController controller("Test");
controller.stop();
controller.start();

Answer 2

Unfortunately, Qt does not provide such kind on API.
You need to look into WinAPI solution.
There is an example on MSDN how to stop a service. Im sure you could figure how to use same approach to start it.
Additionally, you could also check a much smaller example how to both start and stop a service.

You can just use the sc command (this page has some usage info or just type sc on the command prompt).
sc stop Test
sc start Test
So:
QProcess::execute("sc", { "stop", "Test" });
QProcess::execute("sc", { "start", "Test" });
Note that you need to be running in an elevated context to control most services.
You could also use net instead of sc if you prefer, same syntax for starting and stopping.
The parameter needs to be the service key name, not the display name; so if you only have the display name you can run sc query or sc GetKeyName "Display Name" and parse the output.
