high school: when closing the reference?

Hi, just a quick question if anyone can it clearify I thank so much.

I found the secondary example called "Simple Subpanel.vi" and he put an inactive during the loop to "hold" the front of the called vi, here, is the "plugin1.vi". (Sorry I am still not very clear why it must be slowed down while loop here.)

However, if we put the vi 'close' after the while loop, like the one I changed, is there a chance that the vi will overflow from the memory of the PC after the long period of running? What is the difference between these two methods?

Lets say, I load my VI in a secondary, then after it's in high school I want to show or hide the menu bar.  Can I use a node property to show or hide the menu bar of the VI in the secondary, but I can only do this by using the reference to the VI, if it has not yet been closed.  In this case, you don't want to close until you are done with it.

You do not leave open indefinitely in both cases that you have demonstrated, so there is no memory problem with both methods of references.

  • How to configure Firefox 4.01 to save all tabs when closing the browser?

    In the previous version 3.x.y to Firefox, when I closed the browser, he asked me if I wanted to save my open pages / tablets before closing. When I open the browser again, then it rebooted all previously open tabs / pages. In the version 4.01, before avant de fermer close the browser warns me that I'm closing multiple tabs, but when I restart the browser once again, it does not load the already open tabs. How to configure the browser to behave like the old version of 3.x.y, that is perfectly save all open tabs and load these new opening to restart the browser?

    Firefox stores now always the old session, and you can access it by going to the history menu and selecting "restore previous Session."

    If you always open the last set of tabs, another approach is the following:

    1. Click on the orange button Firefox, then select options to open the options window
    2. Go to the general Panel
    3. Change the setting "When Firefox starts" to "show my windows and tabs from last time '.
  • Control arrays disappear when closing the window .uir

    Using LabWindows/CVI 2010, I created a program of simple test with a panel containing a couple of buttons push, three tumbleurs and three control LED. I can create arrays of controls containing the toggle switches and/or LEDs in the .uir editor and access in the program, but when I close the .uir editing window and reopen the .uir file, control arrays are gone from the .uir file and of course when I rebuild the program I can't access it. This happens if I leave LW/CVI entirely or if I just close the editor of .uir. If I explicitly the file .uir after creating tables, everything seems fine, but then when I close the .uir window I see an asterisk briefly appear in the tab of the file name, as if it is modify the file, and then re-register on the goal.

    I can duplicate this just creating one or two control panels and by closing the window. Sets disappear, even though I explicitly save the .uir file after I created them. Is there something I can do to prevent this?

    Thank you

    Brian

    Brian.

    It seems that your UIR may have have been saved for an earlier at some point.  If you open the UIR and look in the lower right corner, you say 'file UIR 2010'?  "Otherwise, you need to click on File ' Save *.uir as and save the UIR under a 2010 UIR.

    If you choose to save the IUR for an earlier version, CVI remembers this decision and always saves the IUR for than the previous version.  You will have to explicitly choose to save them for the current version.

    Let me know if this does not fix things for you-

    Hi logansrun73,

    1. Did you the latest changes on the computer?
    2. You have security software installed on the computer?
    3. You receive an error message when using schedule a task on the computer?
    4. When was the last time it was working fine?

    Method 1

    It is possible that some third-party programs installed on the computer is causing the problem.

    I suggest that you put the computer in a clean boot state and check if it helps.

    To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See section to learn more about how to clean boot.

    Reset the computer to start as usual

    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

    (a) click Start, type msconfig in the search box and press ENTER.

    (b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

    (c) under the general tab, click the Normal startup option, and then click OK.

    (d) when you are prompted to restart the computer, click on restart.

    Method 2

    If the previous step fails then I suggest that scan you SFC on the computer that would be a corrupt system file search.

    The analysis may take some time, so be patient. Windows allows to fix corrupt or missing files it finds. If the information of the installation CD is required to fix the problem, you may be asked to insert your Windows XP installation CD.

    Method 3

    If the previous step fails, you can then restart the Task Scheduler service in the Services snap-in. To do this, follow these steps:

    1. Click Startand then click Control Panel.
    2. Click performance and Maintenanceand then click Administrative Tools.
    3. Double-click Services, click the Task Scheduler service, and then click restart service. Wait for the progress of the Service Control indicator to close.
    4. Close the Services window.

    Thanks in advance!

    Well, I found a solution for the bug here. I was using sockets to communicate between my headless and requests for benefits and in my slot look for disconnect events in my application without a head, I got this code:

    void disconnected()
    {
        ...
        _socket->close();
        delete _socket;
        ...
    }
    

    I then changed this slot to look something like this, that solved my problem:

    void disconnected()
    {
        ...
        _socket->close();
        _socket->deleteLater();
        ...
    }
    

    My guess is that I tried to remove the plug while he was still waiting to be delivered to her events. Using deleteLater(), the event loop is responsible for the removal of the plug once all the events have been delivered, preventing the application from crashing.

  • Security problem in Chrome when closing the browser (4.2.6.00.03)

    Version 4.2.6.00.03

    Hello

    I have just been informed that in Chrome (version 43.0.2357.81 m) and in the settings in the section "getting started", if "Where you stopped to continue" is selected and that the browser is closed by clicking on the 'X' in the top right and then open again the last visited page appears without having to log in again.

    It is of course logical based on the selection in the settings, but the Cache in the browser security is set to disabled.

    Thanks again for your help.

    I could correct this problem. I went into the properties of the Application-> Security-> Session Timeout and entered the Session idle time in the text field instead of depend on the default values of the Skillbuilder Session Timeout of the plug-in.

  • Why Firefox will allow me to have several tabs, but not allow me to switch between tabs and can only watch a new tab when closing the previous?

    Everytime I open a new tab, it appears on the tab bar where it should, but if I click on it nothing happens, the tab does not open, and I can't switch between multiple tabs. The only way to get a new tab is to close one on that I am currently, and even then it will only open the next tab in the order of precedence, so I can't even choose which tab is next to see. This problem makes it impossible to use firefox as a research tool that requires quick change back and forth between pages in multiple tabs at the same time.

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that disables certain parameters, disables most Add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • In Firefox 29,0 and above, click on the menu button

      click Help

      then select restart with disabled modules.

    • In previous versions of Firefox, click on the Firefox button in the upper left of the Firefox window and click help (or click on help in the Menu bar, if you do not have a Firefox button) and click on restart with disabled modules.

    If Firefox is not running, you can start Firefox in Mode safe mode as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. Please follow the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • «.. . handle is invalid': error only when closing the Application, the runtime, everything seems fine...

    Hello

    first of all: I am relatively new to LabWindows, working on it for some practical work as a student

    (Yes and sorry for the bad English, I'm from the Germany)

    The problem:

    The first important Information:

    After searching for a solution, I don't know, what to do,

    My project consists of a Main.uir file with a tab, a 'Main.c' which manages essentially the main .uir-stuff and some stuff-Initiating and in addition to that several Sub-Sourc-files, one for each tab panel of the Main.uir - tab.

    To use the user interface elements on the main tab with secondary Sources, I'm launching tab handles at startup, which can be used by SubSource files, such as:

    GetPanelHandleFromTabPage (PANEL, PANEL_TAB, 2, &BALU);)

    With this controller, I can identify each UI elements when working with secondary sources

    The second important information:

     

    In some of the TabPages in the .uir, there are several ControlArrays. To use them, I create a ControlArrayHandle, such as:

    MWSAverageHandle = GetCtrlArrayFromResourceID (BALU, MWSAverageArray);

    No, I'm able to identify specific paintings, as items:

    SetCtrlVal (BALU, GetCtrlArrayItem (MWSProgressHandle, ActiveBalun), ProgressString);

    Now there is a problem, I am not able to solve:

     

    During execution, everything works fine, I can use all the elements of a ControlArray with this ControlArrayHandle ("MWSProgressHandle"), everything works perfectly, no errors at all. BUT, when you close the program, I get the following error message:

    RUNTIME ERROR NO MORTAL: "Baluns.c", line 313, col 16, id 0x00000AB8 thread:

    Library function error (return value ==-4 [0xfffffffc]). Panel, menu bar or a control table handle is invalid

    But this seems somewhat ridiulous for me, because when executing that each line works perfectly, each element of Array can be used without problem...

    Is it something I'm not able to see?

    Thanks a lot for your help.

    Greeting from Lübeck, Germany!

    Mathias

    In the reminder of your timer, you check for (event == EVENT_TIMER_TICK)? Might get called for various events, not just the one you have in mind...

  • Usually, Firefox closes when closing the last tab on it. Now he doesn't. How can I change to the closure when the last tab is closed?

    I checked my comments: settings beforehand because I hear the setting because it is usually there. It is always the same and has not changed. As far as I know, I have not downloaded Add-ons recently causing this change. None has been installed recently. Here is a screenshot of the subject: config.

    Have you tried Mode safe?

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

    • Put yourself in the DEFAULT theme: Firefox/tools > Modules > appearance
    • Do NOT click on the reset button on the startup window Mode safe
