Loop timed in LabVIEW DLL does not close

Hello!  I have what I think, it is a simple loop timed in LabVIEW that stops after 100 iterations by throwing an error and letting the loop 'stop on error.  It works fine when it is executed in the ordinary LabVIEW environment, however, when compiled as a Dynamic Linked Library (DLL) and called from LabWindows it requires me to put an end to execution, rather than going out nicely.  As well, it seems to leave the real appeal of virtual Instrument very well and go to the next line of code, but when my function main() in LabWindows is completed it must always be something not cleaned which is the cause not come out well.  Any ideas?   I tried to add only a call to QuitLabVIEW and that doesn't seem to do it.

Thanks in advance - hoping you will notice an error really easy. )

A photo of the timed loop is attached.

An excerpt from the code of LabWindows:

int main)
{
CallMyLabVIEWDLL();  This line launches successfully and closed the window for my virtual instrument LabVIEW
MessagePopup ("' My Title:", "That occurs after the call to your LabVIEW DLL" ");    This popup appears - indicating the call to the DLL has finished

But after the code has completed LabWindows always shows "running", rather than close.

return 0;
}

Why do you use a loop timed in the windows environment?  They are best used for real-time environments (not windows) and tend to have more support than the time.

Is there a particular reason, a while loop will not work?

  • VI front panel does not close when it is done executing, when this vi was called by reference.

    I created a simple vi set to indicate the problem I'm having. I run dynamically under vi to leave a main application. Simply the main application is my test exec and the Subvi I call dynamically is different tests. In the example I have write here the criterion vi is called Test electric 1(vi). I configured this electric Test 1 vi to see the front when it is called and close later while initially closed.  Problem is that it doesn't close before.

    Other things to keep in mind

    • I want to be able to run the vi test and do not wait until it is done.

    I'm using LabVIEW 2012 SP1.

    Basically the fence after that call questions only if the VI is called as a Subvi (as if you open you a VI and run it, it does not close when it's done).  Are two ways to work around this or have your app high lvl close the VI when it's done, it's explained here:

    http://digital.NI.com/public.nsf/allkb/987B2026B41BD39786256CF800032E8C

    or having your VI close when it's done.  A reference of the VI and the front panel: Close call node.

    I hope this helps.

  • FP. Closing does not close application.

    When I use FP. Close in my main vi, which is the last step in my code, it stops the program, but does not close the front panel.  Although the program has stopped running, the front remains open.  I would avoid this because operators think it is still ongoing.

    Well, I can not help with you feel, but you have to QUIT LABVIEW in an application.

    No matter HOW you exit you should not do before closing references, files, connections, etc.

    Once you have done all that, then it's time to LABVIEW to quit SMOKING if you are in an application.

    WinHTTP.dll if missing some things just will not start:

    I downloaded a copy of XP Pro SP3 file you need on my SkyDrive (everyone has a SkyDrive for file sharing).

    You can download it and when you do, place a copy of the file in these two folders (assuming that Windows is installed on your C drive):

    c:\Windows\System32
    c:\Windows\System32\dllcache (this is where XP keeps backups of important files).

    Here is the link to my SkyDrive and you can get the file you need here:
    http://CID-6a7e789cab1d6f39.SkyDrive.live.com/redir.aspx?RESID=6A7E789CAB1D6F39! 311

    When you see the files available for download, you can not see the file extension (.exe, .dll, .cpl, .sys, .zip, etc.), but when download you them they will have the right extension.

    When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, your browser is unable to save the file with an extension (by example, .exe, .dll, .cpl, .sys, .zip, etc) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

    You can download the file without the extension, and then rename the file to add the appropriate extension.  You do not want to use a file called winhttp when the name of the file should really be called winhttp.dll (if the downloaded file has no extension, you will need to change the name of the file to add the appropriate extension to make it work.

    You then put the downloaded files in the correct folders on your system.

    To the best of my knowledge iTunes has all of the features that could stop him. What make you believe it's iTunes rather than some other power saving feature? What happens exactly 30 minutes? It's happens during playback video or audio?

  • Firefox does not close completely.

    So since I have updated to the new Firefox it does not completely close when I hit X to close. Then the next time I go to open it it says something like ' Firefox is open but does not close it before trying to open it again. Has not done this before and is getting pretty annoying having to open my task manager everytime I want to open Firefox.

    Is this a new problem with the new update, or something else in conflict?

    In case you use 'Clear history of Firefox closing' and then try to disable this feature.

    • Options > privacy > Firefox will be: "Use the custom settings for history": [] 'clear history of Firefox closing. "

  • roboformtaskbaricon process does not close after that firefox 9 is closed

    Hello

    roboformtaskbaricon.exe (v754) process does not close after that firefox 901 is closed. Even if I'm wrong, my guess is that firefox pushes this process of firefox, forcing him to run on its own. If it's a matter of roboform, then I will contact them.

    Thank you, specialist

    On the next page, scroll down to "RoboForm controls", then scroll down to 4. The taskbar icon under this heading. It seems that maybe the item to which you are referring. Taskbariconroboform .exefile name, it involves the Windows taskbar rather than the Firefox tool bar.

  • App store popup does not close.

    Does not close the pop-up 'Upgrade for os x El Capitan'. It forces me to the app store if I click on it. How can I get rid of him? I am running 10.9.5 on an iMac 2.66 GHz.

    The same window view was on my end 2012 Mini (Server i7) this AM and I first opened the

    App Store, but thought that it won't go away by that alone. There can be no. So I clicked on the button

    in the view of window and he raised point to the App Store of El Capitan. I then read

    through and then rest of the App Store has from here and leave the App Store.

    The notice window went. And I read more than I wanted in the low-score comments

    which have been posted on ElCapitan OS X. My Mini comes with the Mavericks, & is still there.

    No rush to upgrade, since my model has indications (another problem discovered user) when

    updated at ElCapitan regarding material and graphics; This has not been addressed.

    So, if you tried the button in the notice and went to see El Capitan in the App Store, then

    Choose one of the main display options in the App Store before leaving, which can make it go away.

    At least until tomorrow, when you wake up the computer again. Mine is rarely rebooted.

    I hope it will work. Don't know if you need to do anything else that put a piece of

    Black Ribbon on the package insert or create a blind spot in your vision, selectively ignore it.
