What the best way to do it?(get the status of process by using the process name, and kill it if it's open).

code example can help me a lot. Thanks!

Answer 1

You can use Qprocess for this purpose. At the start of your application,Do

Qprocess p;
p.start("pkill processname1");
p.waitForFinished();
p.start("pkill processname2");
p.waitForFinished();
p.start("pkill processname2");
p.waitForFinished();

Or you can use system call directly..

system("pkill processname1");
system("pkill processname2");
system("pkill processname3");

In Windows environment, you can use following commands to kill process

process -k “Process ID”
process -k “Process Name”

You can read more of these here.

Answer 2

Under Windows use taskkill command You can call it using

QProcess::execute("taskkill /im <processname> /f");

Or

system("taskkill /im <processname> /f");
