RemoveAllEventHandler() could NOT put an end to events

Hello

I met a problem when I debug my C++ program for a data PCIe6361 acquisition card. Could you please help me?

The application that we need is to acquire redeclenchables analog input signals for a specified number of cycles. According to your example available online program, I managed to achieve this goal: the components in good condition worked already pretty normal by reading all the data out in the outStream, which could then be saved.

However, I found that the program is stuck to the 'RemoveAllEventHandlers()' function when I tried to stop the task. The function will not do its job, and the process continues to run forever. I myself remember that this function perfectly worked well when I tested it for a task simple start-triggerred. So, I thought that this is the sequence of my functions 'stop process' which give rise to this problem. I tried the variant of the sequence, but no improvement still. I wonder if it could be a systematic bug in the inner workings of the map, or I missed some important steps during the shutdown process.

The essential parts of the program are displayed as below, please advise me what to do! Thank you very much!

Wei

Thank you very much for your answer!

I tried some of the idea of our days, but still none of them seems to be the case. Fortunately, my colleague mentioned there are a few sections using 'measure studio' talk «InstallEventHandler» I realize that regarding the execution of RemoveEventHandler(), I actually includes the 'RemoveAllEventHandler()' and "-> stop() m_task" insdie the OnEvent(), which seems to violate the rules. I then clear upward and the return to normal program.

Thanks a lot again!

    Hi 1234Tony,

    First of all, I suggest you that you also scan your laptop for infection by the virus. Second, reset TCP/IP stack Winsock settings. This could correct mistakes involving internet connectivity as a result of problems of installation of network software, due to a virus, trojan or malware infection or even due to disinfection of spyware security software.

    To repair and put back the Windows Vista

    1. Click the Start button.
    2. Type Cmd in start it the search text box.
    3. Press Ctrl-Shift-Enter keyboard shortcut to run command as administrator prompt. Allow elevation request.
    4. Type netsh winsock reset in the command line shell, and then press the Enter key.
    5. Restart the computer

    My application has a 'Warning' dialog box which must be indicated when the application is launched. There are two options in this regard. If users do not accept the warning, the app will be closed. I put it in the onCreationCompleted event handler in the first screen, but it could not be shown there. But I tried to click on a button to open it, it can be displayed correctly.

    I also tried with the dialog system, it can be shown correctly in the event of onCreationCompleted. But I couldn't use it cause my warning dialog box has a complex user interface design.

  • Windows connection problems and "Windows could not log in the Windows Event Service.

    September 14, 2014, I installed the hotfix for Windows (KB2590550).

    When I try to log on to a standard user account (not Admin), I would get an error that might say something like "Windows could not connect to the Windows Service Service event".  I click OK and then get a totally blank screen showing on the arrow of the mouse (which can be moved).

    Around this same time, when I was able to connect, I got a "not genuine Windows" pop up.  My windows 7 came factory-installed by Dell (Dec. 2011) and I got no re-imaging, re - install or repair since I got the computer.  I've also been running Symantec Endpoint Protection (version DoD) for 2011 as well.

    When I login as administrator (different account), I get an error "Failed to connect to the Windows Event Service" or something like it in a control bar bubble popup.

    I studied the Knowledge Base, and he said to apply the patch to KB2590550.

    Since then, the question is still common and works (sometimes) when I reset the password for the standard user.  In addition, all updates of the operating system, patches, etc. have failed since then.

    Now, I get occasional blue screens immediately as windows starts to load (just after the initial windows graphics) which triggers a reboot.

    Service Pack 1 is installed.

    Help, please!

    Hello

    Thank you for the update on the issue.

    If the problem still persists I suggest to run the SFC scan to check the integrity of the system and see what it finds.

     

    The sfc/scannow (System File Checker) command analyzes all protected system files and replaces incorrect versions with appropriate Microsoft versions.

    We can check & repair missing and corrupt files by the following article in the Microsoft Knowledge Base.

    1. Go to Start, click all programs and open the Accessories.
    2. Right-click on command prompt in the list programs, and then select run as administrator. If you are prompted for an administrator password or for confirmation, type your password, or click OK.
    3. In the command prompt, type the following command and press ENTER:

  • Equium L40 PSL41E: Wireless not connect host process not put end to

    Recently, I got a blue screen on this laptop crash after that get a message telling me a host process had ended.

    The computer is running Vista, so I expect problems when my parents bought my sister this laptop.
    In any case despite the frequent blue screen stop messages, etc.. When I get the message telling me that the host process put an end to my wireless connection gets messed up.

    The last time I used windows: diagnose why Windows cannot find network option and was quickly informed that my wireless was turned off (despite the fact that he was actually turned on) and that the computer would automatically turn back on.

    After that it worked fine for a few days until I had another stop of host process and the computer crashed once more.

    This time, the computer refuses to connect despite the use of the above method and the ConfigFree(Connectivity Doctor), fix the connection etc.

    I give myself the possible Solutions are:

    Check the communication device for bridged settings you may need to disable the bridge or reconfigure. a 15.

    It is certainly not the problem.

    a-9 Move closer to the wireless router.

    Even once is not the problem, I'm sitting next to.

    a-10 tour of all bluetooth devices or other devices that may interfere.

    There are no such devices near to.

    a-11 Check to check a microwave oven is not in use is close.

    It is not in use.

    a 13 make sure that the maximum number of devices connected to the access point is not exceeded.

    Well, it worked for 6 months before that, so I do not know is not the case.

    a 37 to ensure that filtering by mac address of the access point is configured correctly.

    I don't have any idea what it means. But my cell phone girlfriends works very well with the wireless connection.

    a 19 restart the router/access point

    Done several times.

    Well, good suggestions. Fire now that I'm all ears.

    Hello

    I put t know why a host process has stopped working, but to my knowledge, the process could be svchost.exe.
    However, the issue seems to be related to the Vista OS problem

    I see that you have tried to solve this problem, but without being successful, you also get a BSOD so I think it's a serious problem of software and you must first use the Toshiba Recovery CD to reinstall the operating system on this laptop.

    After the new installation (would take about 15 min) update the operating system to the State.
    Then you can try to reconfigure the wireless network

    It's worth to try ;)

    What has removed the error is "double adjustment" the return to C:\ drive.  Apparently once is not enough.  I put the pagefile on C:\ managed and rebooted system.  Then I noticed the mistake of volmgr came from miroir3 (second player in E:\) still info system showed the swapfile on C:\.   Weird indeed.  I went and be given the C:\ drive as the system swap drive to managed by activation/deactivation/Executive every car out of the current value, and then back to the desired direction.  After having done that and restart once more the error no longer appears in the event viewer at startup.

    The only thing worse than a BSOD, no BSOD.
