How App exit/Quit in C++

I now use exit (0) in c ++ which is called from my exit QML button.  Problem is sometimes the application crashes out, but not always.  Is the best way to do it or should I just remove the button and allow the user to use actions to close the application?

Thank you.

in QML:

Application.Quit ();

in C++:

Application::instance ()-> Exit (0)

    Hello

    You can start the Android device in safe mode to troubleshoot your device.
    For example, if you are affected by plant, crashes or problems of battery life, you can boot into safe mode and see if the problems still occur there. Safe mode, you can uninstall misbehaving third-party applications.

    To exit safe mode, press the power button, select turn off and restart your machine in normal mode

  • How to exit properly ChangeDetection thread?

    I call the function ChangeDetection of the NI USB-6525 with C in a C++ program code:

    DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
    DAQmxErrChk (DAQmxCreateDIChan (taskHandle, "Dev1/port1/$line0", "", DAQmx_Val_ChanPerLine));
    DAQmxErrChk (DAQmxCfgChangeDetectionTiming(taskHandle,"Dev1/port1/line0","Dev1/port1/line0",DAQmx_Val_FiniteSamps,1));
    DAQmxErrChk (DAQmxRegisterSignalEvent(taskHandle,DAQmx_Val_ChangeDetectionEvent,0,ChangeDetectionCallback,));
    DAQmxErrChk (DAQmxGetTaskNumChans (taskHandle, & numLines));

    DAQmxErrChk (DAQmxStartTask (taskHandle));

    As far as I understand, this creates a separate thread that defines the USB box - 6525 ChangeDetection mode. When the unit detects a signal change, the C++ program calls a function (called ChangeDetectionCallback() in this case), which runs in its own thread (or perhaps the same thread, but in any case not the thread used to call the above code). It is explained here and is due to the argument of '0' in DAQmxRegisterSignalEvent().

    What I want to know is: while this thread is running (either one created by one of the above functions or whoever runs ChangeDetectionCallback() in), it is ok to quit the program? It could be any problem resulting from resources unfreed, for example? Are there measures should I take to make sure that everything completes successfully, as making sure always to call DAQmxStopTask() and DAQmxClearTask() before you quit the program?

    Hello

    If you click Exit, you must release all resources and the sons who have served in your program.

    You mentioned the right features, if you work with DAQmx, you must stop and cancel the task. If you work with threads (Thread Safe queue for example), it must be released, too. If you opened the file for playback of /writing, you must close them to provide the means and the free memory again.

  • How to exit the camera application properly

    I start the camera application by doing this

    Invoke.invokeApplication (Invoke.APP_TYPE_CAMERA, new CameraArguments());

    The camera app starts. I take a picture.

    I am on a 9000 "BOLD".

    You use the camera you will find that you can not close the app until you get rid of the image sets that you have just taken.

    For example
    take photo

    Picture is a static view of the screen

    If you press close (close menu) it does ' t go away.

    If you press the ESC key, then press close he disappears.

    now in my application, I need to simulate this but I can't seem to get out

    I want to launch the application.

    Press the trackball to take the picture

    Save the photo.

    Then exit.

    I inject

    EventInjector.invokeEvent (new EventInjector.KeyEvent (EventInjector.KeyEvent.KEY_DOWN, Characters.ESCAPE, 10));

    EventInjector.invokeEvent (new EventInjector.KeyEvent (EventInjector.KeyEvent.KEY_UP, Characters.ESCAPE, 30));

    And it closes ok

    BUT... when I opened the camera (for the second time) the image is on the screen, the last shot.

    So, it didn't really come out. The user must press the ESC key stupid and then take another picture.

    Any ideas?

    Thank you

    You test this in the simulator of BlackBerry or on a real BlackBerry "BOLD"?  What version of BlackBerry device software you are using (beneath Options, about)?  Is that you inject events for all the actions in your list or just the ESC key to exit?

  • BlackBerry smartphones how Apps are real in the BlackBerry App World available?

    HY,

    How many Apps are real in the BlackBerry App World available?

    Greetings,

    Pax

    in July 2009, it has been said that AppWorld hosted 2,000 applications.

    If you consider all the applications in each category, you get an upper limit of the number of applications (since an application can belonf to several categories). Today, when I count them in the online store, I get the upper limit of 5309 including games & themes.

  • 10.1.4 update blocks Acrobat Pro, how past exit Code 6?

    I'm on Mac OS with CS5.5 10.7.5.

  • Apps to quit smoking after upgrade iOS 10

    Loved the new iOS update, but since the update, I was faced with a problem. Whenever I try to use a particular application that I use for games (FIFA 16) it keeps leaving himself. Happened several times and I've tried almost all the options: reboot the phone, deleting app and install again, no problem of storage (23 GB free on iPhone 64 GB), but still without success. Any help would be appreciated.

    Details of phone: iPhone 6 64GB, iOS10

    You should try to contact the developer and report the problem, as this is clearly a problem with this application. There is nothing else, you can try on your end. If an application you have installed unexpectedly closes, unresponsive or won't open - Apple Support

  • How to exit while loop with delay schedule?

    I have a pretty heavy program that iteratively takes a series of measures from a number of channels using a variety OR-Switch and OR-DMM screws that I assembled as a result of various examples and several help pages. Each channel is sampled once during each iteration with data to be saved in a text file for later analysis, after it is imported into Excel. I added to the screen 'real time' indicators and charts to see what looks like running data.

    Each iteration is performed using a While loop with a delay timer, even if a previous version, I used a timed loop. Measures for the series of channels are collected with a loop For inside the While loop. The loop For includes screws which:

    1 cut the channel and wait as debounce.

    2 Initializes the DMM and passes the configuration information.

    3. wait for a while to make sure that the DMM is set.

    4. measure.

    5. close the DMM.

    6 disconnect all the switches.

    The terms of the election of the channels is ends in 15-20 seconds and I am currently collecting data every two minutes, so he spends "wait" time "collection". Each iteration of the loop For initializes and closes the DMM to avoid the hot switch.

    Other components of the program are configuration setting controls, etc. (in front of the While loop), a "current measurement" indicator and a writing-text inside the loop file operation For, several indicators of the iteration (inside the While loop, but outside the loop For) and a bunch of operations related to the grouping and table that provide graphics of groups of time vs measures.

    I don't know there are more elegant ways to perform many functions that I do and I'm not posting the VI here because I want to concentrate on what I know, it's a big problem with my program (for now!) - I can't figure out how to get out of the While loop. I tried the combinations of Boolean control, its conditions of latch and Stop / continuous if true to nothing does not.

    I want a 'Stop' button that ends the While loop, at the next opportunity, but it is not working properly, I think, because the stop button does not play with good timing, because the program runs either the loop For or the time delay at the beginning of the While loop. 'Next opportunity' can mean 'Immediately', 'at the end of the next iteration of the loop,"or"at the end of the next delay schedule." I think that if I get one of these scenarios to work, I can get an any of them to work!

    Help, please!
