What is an xnode object?

Okay silly question, but what is an xnode object? I saw them mentioned and I know they have something to do with the scripts. The LabVIEW help search gave nothing of what has been very helpful.

I was playing with these guys a little bit lately and will offer a few thoughts, I won.  XNode is roughly the equivalent of an XControl comics.  It is organized like a normal library, and a .xnode file is basically XML as a file .lvlib.

XNodes have some of the "capabilities" that you control by writing ability live.  They range from the drawing of the image, to specify the terminals to generate the actual code.  There is a lot of flexibility, you can adapt for wire types, resize nodes horizontally and vertically, to have configuration screens, text fields.  The downside is that there are a lot of luggage, IE. all these screws capacity should be around, so a simple VI with a unique XNode may require dozens of subVIs.  No problem when they come with LV, a bit of a brake to home built ones.

I've been a promoter of the end regarding XNodes and I'll soon (I hope) to release my XNode assistant on the community.  It deals with the creation of XNodes and add capacity VIs and SubVIs.  It also simplifies the process for most of the core capabilities.  My favorite part is that it eliminates scripting in many cases.  You write a VI model, use my tool to the terminals of the tag on the comic book by clicking on an image and then simply generate a list of rules of XNode wiring lugs on the terminals of the BD.  I also have simple tools to bundle/unbundle inputs/outputs for expandable nodes very popular.

The old claim was XNodes would be too complex and not the type of the 'customer experience' that LV users want.  I intend to prove them wrong, stay tuned.  Once, they said similar things about scripts...

In the meantime, let me know if you can make sense of this

  • What exactly does Inline object offset 'Y '?

    Hello world

    I'm confused on the subject line y offset. Does that mean exactly? I looked on the help of adobe, here's what it says.

    Inline
    Aligns the object anchored with the baseline of the insertion point. You can adjust the offset Y to position the object above or below the base line. This is the default type of the anchored object. In earlier versions of InDesign, these objects were called graphics.

    Then. the baseline is the insertion point?  If the offset is a negative number, doesn't mean that the base line moves upward? How is the object does not move? assistance from adobe say, 'solve it is offset to position the object above or below the base line', it means not the base line should stay and the object moves as a result?

    Thank you very much!

    The behavior of inlines is also linked to the leadingof of the line in which they find themselves. When the line spacing specified, a line the line begins with the lower edge on the base line and spacing for the whole line is adjusted height of the inserted object. Change the offset y in such cases would appear to make the object appear fixed while moving the base line upwards or downwards. Is happening what is the amount of 'auto' driving is being adjusted to compensate for the offset.

    If the line that the object is inserted using a fixed attack, this attack is in the spotlight, and the inserted object can cover part of the text above. Change the offset will make the Forum appear to move upward or to the low bit at the base, which will be fixed by the assigned key.

  • What should I buy objective 17-40 or the 24-105 Lens Kit?

    Hello again,

    And after the great success of the support team here and advise.

    I'll buy the Canon 6 d this weekend...

    I thought based on my Style (architecture, landscapes, night photography) photography (attached sample of my work)

    to buy the only 6 d body + canon 17-40 F4 as affordable for wide angle type, but i got to know that this cam lens without image stabilizer, which really confused me and return to think again buy the camera with its objective of kit (24-105) as it comes with stabilizer more range and image ,

    So the question, is image stablizer is a must? who advises you to go with?

    Thanks in advance for anything that can advise you in this decision.

    Can you tell me that all of them would be nice to know

    I don't know what you mean.  Those are just different types of files.

    .exe = executable file (a file that contains code that can "launch" to do something, like a program)

    .html = a file that stores the HTML code (the Web site, hypertext markup language code)

    .vbs = a visual basic script file

    .reg = a registry file

  • Anyone know what could be this object?

    I recently bought a windows 7 computer, HP OMNI 220 premium.

    When I opened the packaging, there are not very many regions, but there is one thing I can't understand just what it is about everything.

    Its a very long cord, one end of a form similar to that of a speaker. other end is a red thing (do not know how to describe it) and there papers I can take off (im assuming its meant to stick to something |).

    I thought maybe its some kind of microphone, but it doesn't look like one.

    I thought maybe its used to receive the signal of the remote control that came with the computer, but it fits into the slot of headphone/microphone jack and the remote works fine without it.

    It is the image.

  • Text in Xnodes recovery

    Hello

    Background

    Using Labview 2010, but willing to spend in 2011 if it has the solution.

    I am currently working on a code to go through a VI and check all text for certain keywords. However, I can't catch any Xnodes text. It is my understanding that Xnodes are not supported by NEITHER yet, however, there is text editable in them, and I need to check it out.

    Examples

    I can't get the text to the location of the "open storage" file or the "signals group set up digital" trace the legend.

    Recent attempts

    I tried to use the specific function of class too more but Xnodes is not an option. I also tried to access all other sorts of GObjects by crossing for GObjects function, but none of them were able to recover the text.

    Question is there a way to retrieve pieces of text like this with pragmatism or must it be done by hand?

    Thanks for any help in advance.

    I'm sure you can't do what you want (assuming that I did hear what you want). The whole point of an XNode object is that it can have a custom appearance and behavior. This means that there is no standard way to access things like that, since they would be at different places for different XNodes (or not at all).

  • Paste an object floating in the new doc Pages?

    Exactly, what determines where an object is pasted into a document Pages 09 and is it possible to click and point so a floating image is inserted at a specific time?

    I work with two very large documents (900 inches wide by 11 inches high) containing areas of text and images.

    Document 1 is a rough work space where I assemble images and possible captions for a photo essay. Document 2 is where to place the caption of the image units, while keeping the separate objects. All the objects in the two docs are floating; None of them are online. I scroll back to work on the docs and drag and modify freely.

    I found that when I'm trying to copy and paste an object 1 Doc 2 Doc, if I first click on an object in the Doc 2, element Doc 1 copied will be pasted next to the Doc 2 object (which is usually on the right side of the document, since I work mostly from left to right). But other times it does not work: the object, I'm sticking will appear somewhere in the Middle, or well left of the Doc 2. Which means that I have to drag the path to the right, where I want to. It may take a very long time.

    I know it is not random, but I just can't understand what governs the implementation of an item floating in a document where nothing is online.

    I'm even ready to enter the coordinates of the extreme-right for an object sticking pages left. But Pages don't let me do.

    Can anyone help?

    Thank you!

    This is certainly a very large document.  But try this:

    If there is text after copying the photo and caption in the doc 1, doc 2 (probably your final document), click in the text in the area where you want to paste.  Then the dough, using the command paste in the Edit drop-down list or v on the keyboard command.  That should put the issue in the vicinity where you want.  Then, if it ends up being 'inline', use the Inspector on the right panel and reset the objects "float".  It should work.  However, I, too, find a little strange 5.6.1 Pages.  I prefer Pages ' 09.  He has a lot more flexibility.

    Hello

    I suggest you to follow these steps and check if that helps:

    Method 1:
    If you have installed a security software on the computer, then I suggest you try to disable temporary and check to see if the same problem happens. Make sure that you enable security software back once the diagnosis is made to prevent the computer from virus attacks.

    Method 2:
    Try to perform the clean boot and check if it helps:
    http://support.Microsoft.com/kb/310353

    NOTE: When you are finished troubleshooting, make sure that you reset the computer in start mode normal such as suggested in step 7 of the above article.

    Method 3:
    Try the running System File Checker and see if it helps:
