Detect End Process From Task Manager In C#

阅读更多关于 Detect End Process From Task Manager In C#

问题 I have an application in C#, and would like to monitor its current status, i.e. whether its running or closed. So far i am able to track the status if the application exits during a run time error, or any other in application exit codes. But i am unable to log the application status when it is force closed by task manager. Is there a way to monitor End Process events? or do i have to design a separate service to keep a watch on my application (which i find would be a waste of resources)?

I'm trying to get the video to exit fullscreen at the end of the video but it won't. I searched and found ways to do this but for the life of me I can't get it to work. I'm testing in the latest version of Chrome (15) and iOS 5 on the iPad2. Here's the code I'm using: <html> <head> <script src="http://code.jquery.com/jquery-2.1.3.min.js"></script> <script> $(document).ready(function(){ $("#myVideoTag").on('ended', function(){ webkitExitFullScreen(); }); }); </script> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>854x480</title> </head> <body> <video width="854"

Exiting Python Debugger ipdb

阅读更多关于 Exiting Python Debugger ipdb

I use ipdb fairly often in a way to just jump to a piece of code that is isolated i.e. it is hard to write a real script that uses it. Instead I write a minimal test case with mocking and jump into it. Exemplary for the workflow: def func(): ... import ipdb ipdb.set_trace() ... def test_case(): ... func() ... Then, invoke py.test test_file.py -s -k test_case Now, usually I just check one variable or two, and then want to quit. Change the code and do it over again. How do I quit? The manual says q quits the debugger. It doesn't (really). You have to quit a few times before the debugger actually

Process stuck in exit, shows as zombie but cannot be reaped

阅读更多关于 Process stuck in exit, shows as zombie but cannot be reaped

问题 I have a process that's monitored by its parent. The child encountered an error that caused it to call abort . The process does not tamper with the abort process, so it should proceed as expected (dump core, terminate). The parent is supposed to detect the child's termination and trigger a series of events to respond to the failure. The child is multi-threaded and complex. Here's what I see from ps : F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND 0 1000 4929 1272 20 0 85440 6792

Prompt on exit in PyQt application

阅读更多关于 Prompt on exit in PyQt application

Is there any way to promt user to exit the gui-program written in Python? Something like "Are you sure you want to exit the program?" I'm using PyQt. ire_and_curses Yes. You need to override the default close behaviour of the QWidget representing your application so that it doesn't immediately accept the event. The basic structure you want is something like this: def closeEvent(self, event): quit_msg = "Are you sure you want to exit the program?" reply = QtGui.QMessageBox.question(self, 'Message', quit_msg, QtGui.QMessageBox.Yes, QtGui.QMessageBox.No) if reply == QtGui.QMessageBox.Yes: event

Stopping a JavaScript function when a certain condition is met

阅读更多关于 Stopping a JavaScript function when a certain condition is met

I can't find a recommended way to stop a function part way when a given condition is met. Should I use something like exit or break ? I am currently using this: if ( x >= 10 ) { return; } // other conditions; Return is how you exit out of a function body. You are using the correct approach. I suppose, depending on how your application is structured, you could also use throw. That would typically require that your calls to your function are wrapped in a try / catch block. Starx use return for this if(i==1) { return; //stop the execution of function } //keep on going The return statement exits a

For example consider following code: int main(int argc,char *argv[]) { int *p,*q; p = (int *)malloc(sizeof(int)*10); q = (int *)malloc(sizeof(int)*10); if (p == 0) { printf("ERROR: Out of memory\n"); return 1; } if (q == 0) { printf("ERROR: Out of memory\n"); exit(0); } return 0; } What does return 0 , return 1 , exit(0) do in the above program? exit(0) will exit total program and control comes out of loop but what happens in case of return 0 , return 1 , return -1 . return from main() is equivalent to exit the program terminates immediately execution with exit status set as the value passed

Is it up to the programmer to deallocate on exit()?

阅读更多关于 Is it up to the programmer to deallocate on exit()?

I have a program and when I input wrong data from the keyboard it just exits with exit(1) . I was testing with Valgrind and while this happens there are no errors, but I can see that there are still reachable x bytes. So my question: Is it up to the programmer to free memory before hitting an exit() or is the OS going to take care of it? It's a good idea (and in old enough versions of Windows, it was essential), but when a program exit() s on modern operating systems its entire address space is reclaimed. In the end, the OS will take care of it (on every modern OS, it was not the case with
