Correspond to an expression that VI grey regular

When I place the VI "matches regular expression" in the range of string on a remote system, the VI is grayed out. Move the cursor over them does not help information. Any idea of what is the cause?

Stephen

The 'Match Regular Expression"primitive is implemented as an Xnode object.  I don't know if there are constraints in support for these during the development of code to a remote target.  A person of OR could probably answer.

You told us what is the target system.  It is perhaps useful info.

Just out of curiosity, rather than trying to put "Regular Expression to Match" on your comic, you can click the right button, and then in the functions palette, choose "select a VI...". ' (see note below), then navigate to your LabVIEW installation path (probably C:\Program Files (x 86) \National Instruments\LabVIEW 2013, but can vary), then vi.lib\regexp\Match Expression_Execute.vi regular and place this VI?

If it works, you basically have the "courage" of the primitive/Xnode.  It is not expandable as the XNode, but if you need it, all the submatches are available in the form of an array of string to a lower bound.

I'm guessing that, for some reason, you won't find this record of support 'regexp' under vi.lib, who must confirm at least the 'why' of the primitive in gray.

Note: If the option "select a VI...". ' is not present, pin the palette of functions (upper-left), customize, pallets of Visible change, place a control, click OK, blah blah...

  • Satellite A200 - 1 M 5: sounds from the HARD disk that is not regular

    Dear,

    I bought a new Satellite A200 - 1 M 5 1 week there are, but I have noticed a noise coming from your hard drive that is not regular, whenever the drive is currently in use, there is a noise from him. It's weird, I had Satellite phones precedents and never faced that.
    is this normal in this series of satellites? or damage my hard drive? Although it works very well so far.

    If anyone has an idea about this, please let me know it.

    Appreciate it.

    > Whenever the drive is currently in use, there is a noise from him. It's weird
    Who is normal behavior that the HARD drive makes sounds while working.
    On some disks, the sound is louder and some drives are quieter.

    My laptop comes with a 100 GB HARD drive and I noticed that this HARD drive work harder than the previous 40 GB HARD disk.

    I don t think that there might be a problem with your HARD drive. It of new.
    So, in my opinion you should t be worried.

    and if the HARD drive is going to die your warranty covers the replacement ;)

  • Expression that changes continually position there?

    How can I write an expression that passes my layer constantly within 10 pixels of each axis y?

    You must specify a starting position in one way or another.

    In this example, the layer will be to the value of the key to their inPoint, but you can set the start value to what you want.

    pos = value;
    pos[0] += 10*timeToFrames(time-inPoint, 1.0 / thisComp.frameDuration,true);
    pos;

  • The call for an expression that is stored in a single location (such as a link, or an 'include')

    I would like to make an expression (for use on different layers throughout several compositions) which triggers a primary expression that is stored in a place... (maybe it would be an expression on a layer on some fake computer unused or as a text file, if possible).

    In terms of programming, it's like the use of an include file.

    Is something like this? The goal is to allow editing of all instances of a place.

    Thank you

    If you store your expression in a text layer (named "expression_layer" in this example), you can run it with the function JavaScript eval(), like this:

    eval (thisComp.Layer("expression_layer"). Text.sourceText.value)

  • I have somehow lost my tab bar. It contains tabs that I use regularly. Help.

    With Windows 10, I had a horizontal bar at the top which held in tabs, I want to use regularly. This horizontal bar set of tabs disappeared, as well as the button to reveal the legs of overflow (which had no place on the horizontal bar).

    First of all - what I did to lose who together bar and second why is so amazingly difficult to bring?
    I don't know about groups of tabs. I'm not interested by this at this time.

    Other toolbars are visible?

    If no: Make sure that Firefox is not in his view full screen. The F11 key toggles between normal display and full-screen.

    If Yes: The bookmarks toolbar can be turned off. You can use one of the following methods to display the toolbar list and activate the desired bars it:

    To enable the bookmarks toolbar, bar of menus or other bars, click it in the list.

    Does it work?

  • There is an expression that allows you to switch between the layers of all other images?

    A bit like flicker back between two layers. I'm guessing that add that an expression to the opacity of the top layer would do.

    Thank you

    Josh

    Something like this applies to the opacity of the top layer:

    f = timeToFrames(t = time + thisComp.displayStartTime);
        if (f % 2 == 0){
    0}
    else 100
    

    It's just a simple java test for even numbers

    Hope it's what you want.

    Another variant would be:

    f = time / thisComp.frameDuration;
    s = Math.round(f);
    
    if (s % 2 == 0){
    0}
    else 100

  • A site that I use regularly has buttons that I can use to navigate - but 1 has disappeared since the last update of FireFox - and I can't use it.

    For 2 years, I use a site that I order my products through. One of the buttons is my account, the other is the catalog (many others besides these - but these are the ones I use frequently).

    After the latest update of FireFox (3.6.15)-, the 'catalog' button has suddenly disappeared. I thought it was a problem with the website of the company, but when you can access my account (using an older version of FireFox) - the button catalogue presented themselves.

    I tried to clear my cache and restart firefox - several times. No dice. Unable to get him back.

    I have screenshots to show the problem - with my computer and my computer suppliers.

    I have this problem a lot - just selection boxes do not appear in FF, but they appear in fine opera. It is of a workaround, we need the fix a problem.

  • How can I activate Firefox redirect to another part of the site that I use regularly without asking permission

    I use a site about 2 or 3 times a week. After registration on the site, it should redirect me to another page but always request my permission to allow.
    In tools, Options where it allows me to give automatic approval to be redirected. Otherwise, I'm sitting watching the screen waiting for him to change, having not noticed ther bar at the top of the page, pending!
    Thank you

    Is there a way to allow the page redirect specific areas? For example, by using a trust list?
    There are a few sites that I use always demanding redirect, for example after the connection, but I don't want to allow redirection to any site.
