Buttons does not return to the early state in the state machine.

Hello

I downloaded a program that is used to back up data. I used a machine to States with different States. State 1 is initialization, where it moves automatically select the State, which allows to select one of the remaining States to copy the data. The selection is made by command buttons. Once u pressed a button, it goes to that respective State and in this state when you press the backup, the backup of data occurs. Once the backup is located the program goes back to the selection state. So far, it works fine. The problem then. Once he returned to the selection state after that copy was made, then none of the buttons are working properly. Then when it goes back to select State and I tried to select a State, nothing happens, not even the stop button works. I don't know why this is happen. Please help me solve this problem. Thanking you in advance.

You have many States where you have the event structures ("All data" "given more older that '" young data that ' 'Defined Data') (worse there are two of them in "Data set")

Each of these event structures are for a "Backup" mouse event down.  A singularity is now why you use a mouse event down on a button.  This really should be a value change event.  But this is not the big problem.

The big problem is that all of these structures events are set to lock the front until the end of the case of the event.  Well, when you click the mouse down on this button, all 4 of these structures tail event this event.  If you are luckly, one of the event will execute and process the event.  Others, that you will never run because the state machine will not get through these cases.)

You have multiple structures of event you VI and certainly not buried in the event.

Reading guard and recommendations when using events in LabVIEW

Then fix your VI architecture.  You must limit the structures of the event or a separate parallel loop, or to a single case of your state machine that your code will frequently return to, without any other user interaction, in order to service the structure of the event.

  • Phone button does not return to the screen of the phone on the Treo 680

    I had a Treo 680 for the past two years. Software is listed as Treo680 - 2.11 - ATT, which I think refers to the update that came out a year ago. But the other day, the phone button (left) brings me to the Favorites screen instead of the phone's screen. I can't understand what I did, assuming that I did anything to make that happen or how do go back. When I check the personal touches, preferences, it lists the phone to phone button, and you can not choose something different.

    Any ideas?

    OaklandRobb,

    Are you sync'ing the new device the same username in Palm Desktop as an older device?
    If you are, this will cause problems on the new device. When you synchronize the device, it records the device settings, applications, 3rd party, preferences, etc. in the backup folder in the folder on the PC username. When you synchronize the new device it copies the content of the backup for the old device folder in the new device. This will cause corruption in the settings of the new device, which causes erratic behavior of the new device.

    Here are the instructions for the hard reset and rename the backup file procedure. This procedure will not be re - install any 3rd party applications. You will need to re - install these applications. If you do not have the applications. on your PC for re-setup, you can take the apps. Copy the renamed backup folder, those in the newly named backup folder. When you synchronize applications will be installed. on the Treo.

    Looks like you may need to reset your device and rename your backup folder. Go to http://www.palm.com/cgi-bin/cso_kbURL.cgi?ID=887 and follow the directions to do a hard reset. Then before of you hotsync your data back you will need to rename your backup folder, to do than go here.

    XP
    C:\Program files\palm or palm one\ [hotsync username]------and rename your backup
    file Backup.Old

    Vista
    Start--> documents\Palm OS Desktop\ [hotsync username]------and rename your backup
    file Backup.Old

    Then hotsync from your current name of hotsync and all your contacts, calendar,
    tasks and memos coming back.

    Show the file extensions for XP or Vista

    XP
    If you cannot view the extensions of file on your PC I would you open a
    folder, go to Tools--> Folder Options--> View (tab) and under Show hidden
    files and folders to uncheck Hide extensions of known file types.

    Vista
    Open control Panel, go to--> View (tab) and under show hidden folder Options

    You can click right back or front button to open the history list.

    You can hold down the left button of the mouse either back or next to the history tab list opens.

    The current active entry has a bullet in front of it.



    If you place an entry in the historic session with the mouse tab, so you see an arrow to the left pointing (rear) left or right (forward) to show the direction.

    You can left click on an item to open it in the tab active or middle-click or Ctrl, click on an entry in this list to open that link in a new tab, just as you can with the other links.

  • Why not Firefox 4.0 back button does not work since the homepage or google search?

    I've just upgraded to firefox 4.0 tonight, and the back button is not working properly of my homepage or certain types of google searches.

    I can reproduce this problem every time by following these steps:

    (1) open a new tab, and I get a blank page.
    (2) select the Home button. I find myself at http://www.google.com/ig
    (3) go to the address bar type in a new URI, and press return

    Now, I leave my home page and go to the new page, but I can't go back to my home page.

    Similar behavior happens if I do a search on google for the address of quick search in the upper right.

    (1) start a new tab.
    (2) enter a search term and press enter
    3) click on one of the links to research and you transition to the new page, but the back button does not work.

    It works fine if I do something like:
    (1) open a new tab.
    (2) enter google.com in the address bar and press to enter.
    (3) do a GOOGLES search arae.
    4) click a search result link.

    This works very well for me.

    In my case, I turn off the Add McAfee SiteAdvisor 3.3.1 and the problem goes away.

  • Download button does not appear for the reader to download

    In 23 Firefox or Chrome 28, the download button does not appear on https://get.Adobe.com/UK/reader/

    I realize there are statements regarding anti-virus software (I have Kaspersky Internet Security 2013) but I seem to be all set parameters that would have an impact on this process (for example the anti-banner).

    I got the drive via another link on the site, but thought it would be interesting to try to solve this problem for others who may be affected by it.

    It seems that it was indeed caused by a parameter in Kaspersky Internet Security - the Web anti-virus setting.

    I put https://get.adobe.com/ * as a trusted URL and the download button is now displayed.

  • Volume up button does not work like the shutter of the camera

    I have an iPhone 5 with iOS 9.2.1 (13D 15). The volume up button does not work on it like a camera shutter. I think that it used for, and iPhone to my wife 6 with the same iOS version works fine. It is a problem, because I am using this phone with a stick of selfie, which triggers photos by simulating the volume press up button, so it doesn't work at all for me. The physical button works - I can control the volume with her settings. And when I try to use the stick selfie, I get the volume until the display on the phone, so I can see that the signal of the selfie stick is received correctly by the phone. And the stick of selfie works with my other phone that is not a problem with the volume up button.

    Work began after restarting the phone. So it's a bug to Apple report, the solution is to reboot the phone.

  • CLOSE first button does not work, but the second is

    Hi, I'm working on a new web site using Flex 3, but I have a weird problem where I got no information yet on the issue. I opened a TitleWindow to display a full-size image where I want to show a close button at the top and bottom of the image, a close button (some images are very huge and it is the purpose of the TitleWindow). The close button in the button works fine, but one upstairs work not at all (but it appears correctly). What I tried to do was to create 2 HBox inside an HBox. The two HBox are called hbox1a and hbox1b. In the hbox1a, I put a tag that contains the title of the image. In the hbox1b, I put the close button. But the "close" button down is not inside an hbox, pay only the next component in the TitleWindow.

    If anyone can help me to understand why the first close the (top) button does not work, I appreciate to understand.

    Thanks for any help!

    Well! It is always good to be able to respond to ourselves, but it was fast! Maybe because to explain on this forum has been a good thing to clean the idea!

    In any case, I decided to create a new function to close the TitleWindow where I decided to pass the ID (name) of the TitleWindow instead of the event.currentTarget.parent and it works! So I think that I can reduce this to a single function and use my second function for the two close button.
