Can I 'read' a control value that has not been committed?

In short, I would like to specifically to bypass convention of LabVIEW which is a value only committed when the user moves the focus, press the button enter, click on a button to increment, etc..

My specific scenario is I want to respond to button Up/Down/whatever of the events for a given control and enter the value so I can update the graphic interface in real-time as numbers are entered.

I had thought about using the "Selected" the reference FocusObj property to remove the focus temporarily to force the value to be committed, but it seems to do nothing, at least not the way I use it. I also tried to use this property to choose something else entirely before selecting the original order, but once again, nothing.

I imagine that an XControl MIGHT be able to do something like that, but I will abandon the effort before I'm dipping my toe into these waters.

TLDR: Is it possible to cheat and capture the contents of a control, while the user is still typing in there?

In addition to what nathand said, it is perfectly correct.

If you need capture an event in the event structure, instead of 'Change of value' you better to handle the keydown event and take the property Numeric.Text for the property Value will not be changed, but you will have access to what is indicated on the control.

If you do what johnsold says, then the value will be updated after each character, this only applies to controls of the channel.

  • I tried to buy my book - DEFAULT TEXT - your book seems to have default text that has not been modified. Printed books will not include this text. This means all my text will not print?

    Using OSX El captain on a desktop iMac. iPhoto 9.6.1

    I tried to buy my book - this box appears - TEXT by DEFAULT - your book seems to have default text that has not been modified. Printed books will not include this text. Does this mean that all my text will not print?

    I've been twice now and change the text of Bradley Hand to the Blackboard to Helvetica Neue - which seemed to be the default. Message remains displayed. I don't know what else to do. This is my third book over the years, but the first with this problem. Can someone advise please?

    Thank you Davina

    It is not a problem of fonts. It is the problem of the sample text entered by the models.

    The error message means that there is a text field in your book which is still on show at the text included by the model, and you will need to replace this text with your text. This textfield might be hidden behind a picture.

    If you create a preview of the book, such default text is omitted. Have you compared the preview of what you see in iPhoto? Text that shows in iPhoto, but not in the preview will be such default text.

    For example, the section 'Topic of this book' on the flap back in some themes is a default text that should be replaced by your own legend:

  • Update on a laptop that has not been used in almost 1 year

    My husbands cell phone has not been used since last October. He was diagnosed with leukaemia, shortly after he had and has not shown an interest to learn to use it until now. It has Windows 8 and we want to do the free update of Windows 10. The laptop wants to 79 updates before we start download Windows 10. He has been on and downloading these updates for more than 3 hours and the screen still says 0% complete. Is it normal to take so long after being unused for so long? Husband and I went to the challenge of the technology. Any help is greatly appreciated.

    There are many updates and update process may take several hours. You can suddenly find that updates show that almost complete.

    If there is anything on the laptop that you want to keep:

    Download and create a Windows 8.1 installation media and do a clean install of it. See creating installation for Windows 8.1 media. Accepting any offer to install updates during installation. 8.1 Windows installation media last will accept the keys to Windows 8. If your key is in the BIOS of the laptop, it will be detected automatically.

    At the end of the installation, you will be prompted to upgrade to Windows 10 and will be able to do an immediate upgrade Windows 10 without updating the Windows 8.1 installation.

    Visit the support of the manufacturer of your laptop to see if there are model specific drivers you need. Installing Windows 8.1 and 10 will not provide the latest drivers.

    If you want to keep the existing installed applications and files, you can create 8.1 Windows installation media and run the setup.exe on it then in Windows 8.

  • Can I use Windows 7 Upgrade media to upgrade a Vista computer that has not been upgraded to service pack 1? Can I use the option of custom Setup for Windows 7 Upgrade media? I would go from Vista Home Premium to Windows 7 Premium.

    The computer on which I am trying to upgrade is vascular under Vista Premium, but it was never upgraded to Service Pack 1. He has a problem with PIECES that is caused by a defective ntdll.dll module and so the updates do not work. Windows Upgrade Advisor tells me I must update Vista SP1. I really don't want to spend the time to solve the problem of Vista. I would like to just do a clean install using the custom install option on the Win7 upgrade support.

    Wrong forum. This post here instead, questions please: http://social.answers.microsoft.com/Forums/en-US/w7install/threads

  • A new YouTube-Apple TV question that has not been requested here!

    A few years ago, I bought 2 apple TV.   One of them I gave to my daughter and her husband and I kept.   As everyone knows, who has more AppleTV, earlier, YouTube has been removed.   We found that it was because Google has changed the app so that it only worked on the latest AppleTV.   Well, I was resigned to it and decided I would get a new when I had the money for it.  Time passed.

    BUT a few weeks age, my daughter told me that YouTube has suddenly appeared on his Apple TV!  Amazing!  But he did not go back on my own!   I checked my updates and I later.  So what's happening?  Why it come back for her and not me?   And there at - it a setting I can do to bring it back?

    Is is possible that you and your daughter have different generation?  The youtube API supports more generation 2...

    have you updated your software?

    It is now easier to recover a Microsoft Word 2010, Microsoft Excel 2010, or Microsoft PowerPoint 2010 file if you close your file without saving the changes, or you want to review or return to a previous version of the file that you are already working.

    As with previous versions of Office, allowing the AutoRecover in Word 2010, Excel 2010, or PowerPoint 2010 will save versions while you work in your file at the interval you select. Now, you can choose to keep the last saved version of a file automatically if you accidentally close the file without saving the changes, you can restore the next time that you open the file. In addition, while you work in your file, you can access a list files for automatic registration from the Microsoft Office Backstage view.

    Important You must have the AutoRecover information record... and keep the last saved version automatically if I close without saving the changes enabled for these features to work. To learn more about these options and how to configure them, see automatically save and recover Office files.
