问题 I'm finding it extraordinarily difficult to categorize and account for what events I get (or don't get) when the user swipes my app up in the app switcher on iOS 13. This seems to be because of changes caused by the multiple scene support. What are the events that I get in that situation? 回答1: Let's assume that your app supports window scenes. So what the user is swiping up in the app switcher is really a scene , not your app as a whole. Then the possibilities appear to be as follows. On an

问题 I am using std = subprocess.PIPE and checking a particular term in every line of the output.If I get 'done', I manually kill the subprocess by os.kill : p = subprocess.Popen(['vprobe' ,'/vprobe/myhello.emt'], shell = False, stdout=subprocess.PIPE, preexec_fn=os.setsid) while True: line = p.stdout.readline() logfile.write(line) if re.search("done", line): break print "waiting" os.kill(p.pid, signal.SIGINT) The process does get killed (i checked using the 'ps' command in unix) but at the end I

问题 What happens here is I call the crop image activity and then the camera activity runs in background. When I finish this activity, the camera is still alive at the background. So how can I kill programmatically the camera activity running in background? Intent newIntent = new Intent(); newIntent.setAction("com.android.camera.action.CROP"); newIntent.setClassName("com.android.gallery", "com.android.camera.CropImage"); newIntent.setData(selectedImage); startActivityForResult(newIntent, IMAGE

问题 I'm new to programming. I have a form application that launches a thread. Form there 4 new threads are launched. Each of these threads performs a series of command line processes like the following: ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.WorkingDirectory ="C:\\BLA\\bin_windows"; startInfo.UseShellExecute = false; startInfo.RedirectStandardOutput = true; startInfo.CreateNoWindow = true; startInfo.FileName = "SomeProcess" Process p = Process.Start(startInfo); p

问题 I run my C program on Mac OS. Part of my program is as following. This code runs well on sigint signal but can't work on sigkill signal. void sigkill(int sig){ /*some code neglected*/ exit(0); } void sigint(int sig){ flag=1; } void alive(void) { signal(SIGINT, sigint); signal(SIGKILL, sigkill); alarm(10); while(1){ //printf("%d\n",flag); sleep(1); if(flag==1){ printf("no\n"); flag=0; } } } I have four questions: At first I didn't write sleep(1) , It can enter the function sigint(), and change

问题 I wrote the codes below to close all IE (Internet Explorer) Processes. private void Kill_IE() { Process[] ps = Process.GetProcessesByName("IEXPLORE"); foreach (Process p in ps) { p.Kill(); } } The problem is some opened IE windows show an alert : alert("do not close my web site"); //in JavaScript or a confirm_box("do you really want to exit?" , "YES|NO"); //in JavaScript before exit( Unload_Form ) and my program can't close those windows. How can i ignore those alerts and force close those

问题 Is there a way in Qt to terminate a'la TerminateProcess the current process? QProcess::kill() seem to be only applicable to other, external processes. 回答1: Here's my code for win/mac/linux, though not portable for other OSes. void killMe() { #ifdef Q_OS_WIN enum { ExitCode = 0 }; ::TerminateProcess(::GetCurrentProcess(), ExitCode); #else qint64 pid = QCoreApplication::applicationPid(); QProcess::startDetached("kill -9 " + QString::number(pid)); #endif // Q_OS_WIN } 回答2: Just call

问题 I exec into Docker container with docker exec -it container-name bash Inside container I run command ps aux | grep processName I receive a PID and after that I run: kill processId but receive: -bash: kill: (21456) - No such process Am I missing something or? I know that Docker shows different process IDs from top command inside the host and ps aux inside the container (How to kill process inside container? Docker top command), but I am running this from inside container? 回答1: That response is

问题 I have a program developed in C. I added to this program a sigaction handler inorder to execute some C code before quit the program: void signal_term_handler(int sig) { printf("EXIT :TERM signal Received!\n"); int rc = flock(pid_file, LOCK_UN | LOCK_NB); if(rc) { char *piderr = "PID file unlock failed!"; fprintf(stderr, "%s\n", piderr); printf(piderr); } exit(EXIT_SUCCESS); } int main(int argc, char **argv) { struct sigaction sigint_action; sigint_action.sa_handler = &signal_term_handler;

问题 (Question revised, now that I understand more about what's actually happening) : I have a script that runs in the background, periodically doing some work and then sleeping for 30 seconds: echo "background script PID: $$" trap 'echo "Exiting..."' INT EXIT while true; do # check for stuff to do, do it sleep 30 done & If I try to kill this script via kill or kill INT , it takes 30 seconds to respond to the signal. I will answer this question below, since I found a good explanation online. ( My
