Event number: graphics update, while changing the setting

Hello

Here's the Setup, I am trying to achieve (please, see the scrrenshots below):

  • quadratic equations with 3 parameters a 0 x and l
  • an and x 0 are controlled by sliders whreas l is controlled by the knob, which generates a random value
  • When some of these 3 parameters, graphic changes must be updated

I realize that VI using the structure of the event, which has 3 cases of the event:

  • timeout
  • changes, x 0 or a l
  • the button updated l

When one or x 0 change, the concept works perfectly, while the new value l only change indicator, but graphic only is not updated.

Where I have been deceived.

Thank you

Pavel

When you change by program a front panel control or indicator, it does not generate an event to change the value.  To get an event to change the value of I, you use the Value property (signage) for me in your Generate I change of value.  Right-click the I indicator, choose Create property Node, choose the Value property (signs), he set to Write and connect the new value of I in.  Note that you do not need to wire in I, himself.

    When I change the setting by LabVIEW on my device, I see change on the monitor of the device?

    This question should be addressed to the manufacturer of the device. From your previous posts, I guess you use GPIB or serial. If the unit has received the order, the manufacturer should be able to tell if no indicators on the device to update when the order is received. Based on my experience, however, the device indicators will most likely update on receipt of an order successfully.

    If you want to change the boot order, I recommend pressing the F12 key, immediately after that the laptop was turned on!

    A new start menu should appear, then you can choose the reader of CD/DVD (ODD) and a boot device.

    Also by pressing the C button should allow you to boot from the CD inserted, bootable.

  • How I bounce back without having to change the setting of 'Protection against overload only' amateur off EACH time?

    How I bounce back without having to change the setting of 'Protection against overload only' amateur off EACH time?

    This setting should be preserved, once you set it... so I'm not sure why you have to define every time...

    Then... Make sure that you put on ALL the tools of the art of logic in the preferences of LPX...

    Otherwise... you may need to reset the prefs of LPX... Put all the Tools Advanced again and the other preferences you have set... and see if that fixes things for you...

    You can resolve many issues by restoring Logic Pro X back to its original settings. This will not affect your media files. To reset your settings preferences of the user to Logic Pro X to their original state, do the following:

    1. Logic Pro X to quit smoking
    2. In the Finder, select go to folder menu reach.
    3. Type ~/Library/Preferences in the field 'go to folder '.
    4. Press the Go button.
    5. Delete the com.apple.logic10.plist file from the Preferences folder. Note that if you set custom shortcuts, it will reset to the default values. You can export your custom key as a preset before performing this step. See the Logic Pro X user manual for details on how to do this.
    6. If you are having problems with a control surface in Logic Pro X, you can also delete the com.apple.logic.pro.cs file in the Preferences folder.
    7. Restart the computer.

    Note: If you cannot find the files listed above, you don't follow the instructions properly!

  • Change the setting for the acquisition of IMAQ1394 speed by program

    Hello

    I use a pilot LabWindows/CVI and legacy NOR-IMAQ IEEE1394.

    I want to put the acquisition of speed setting in my program.

    MAX can do (there is a drop down menu to change the speed of 100 MB / 200 MB / 400 MB.)

    How can I apply this in my program? The problem is that I can't find the attribute to modify.

    For example, for the brightness, the attribute IMG1394_ATTR_BRIGHTNESS is?

    But for speed?

    If I take a look at niimaq1394.h I see a data type of enumeration, but nothing else on the speed.

    Any help would be appreciated! Thank you.

    Kind regards

    Change the settings for what?

    If you want to say to these forums as they are supposed to be the language you want to search the forums rather than the region in which you are. So, it is expected that English (UK) you use English (United States) at the top of the page.

    I know there are differences between British and English English American, but for the purpose of these forums its regarded as close enough.

    BTW - I'm in England too.

  • How can I keep windows update to change the location of folders of rediredcted

    My work computer is in a domain.  I am running Windows XP Pro SP3.  Due to the large size of the 'My pictures' folder I redirected it to on of my local readers rather than let him lie on our server (Windows 2003 SBS).  I also redirected "My music" folder on a local drive and the 'My Favorites' folder on the server where the "My Documents" folder is also.  It works very well without any problem, most of the time.  In some way, some, but not all, windows updates will change the location of the "My pictures" folder on the server.  When this happens, I know that as soon as I login after the reboot because it will take about an hour before the computer can be used.  The reason for this is that the folder is moved (not copied) on the server with a connection to ethernet 100 base-T.  My another stay of redirected folders where they are supposed to be, just the 'My pictures' folder is moved.  I tried to find all the registry entries that have to do with the location of this folder and found only two, those who originally, I changed to redirect the folder in the first place.  This has happened for the 4th time, when I greeted Windows Update to install the latest updates last night (13/02/13).  It becomes very boring and time would trust because I have to put the folder on the local drive and reset the folder redirection and the whole process takes about an hour, plus time lost after reboot.  Help please.

    Hey there,

    From the start screen, by scanning the right to appear charms, press 'search', type 'power', press 'settings' touch 'power options', this will open a window in the office. On the left side of this window, you will see an option called 'change when the computer sleeps,' touch this, change the settings you want, touch "save changes" and you're done.

    Hope that helped,

  • I can't change the setting of the blue link at the bottom of the ACR

    I was able to change the setting up a few weeks ago. Apperently at some point this has changed on its own default value and now my pictures are very low compared to how I shot them. The screenshot shows what I see when I click on the blue link. Please, I hope it is easy. I don't want to uninstall and reinstall photoshop CS6.

    Without demotion no cab.

    The new workflow options are actually a lot better, because you are not locked into preset sizes among other things.

    (camera raw 8.1 you can get other sizes other than the settings in the options of workflow using the crop tool in acr)

    Regardless of the changes in the workflow options in what size, can be seen at the bottom of the dialog box camera raw before leaving the workflow options.

    (does the same thing as the old workflow options, just with much more choice about how, without the fixed sizes.)

  • Management while changing the value or by clicking on the button events

    Hi all

    I'm working on Jdeveloper 11.1.1.5.
    I have a necessary requirement where I have a textbox and a button.
    Now, if a user changes the value of the text box then I need to display a dialog to the user for confirmation if he wants to continue or not.
    And when the click on the button that I perform my logic and engage in the database.
    NOTE:-I'm going to open this dialog box on the valueChangeEvent of the text box.

    Case 1: -.

    User displayed on the dialog page and enter a value in the textbox control, and a tab on the ground, the value change occurs. -> OK

    Case 2: -.

    The user enter a value into the textbox control and do not tab on the field and directly click the button. In this case, actually valueChange and button code both runs at the same time. I mean, the user clicks the button, the dialog box get, but my logic is also performed. -> INCORRECT (ISSUE)

    How should I limit the logic of the button should be executed until the dialog box has been established and the user has confirmed.
    Please suggest!
