  1. The context help for the "RemoveXnode" method says "Removes the XNode from the diagram. The contents of the diagram of the XNode are merged with the diagram" However if you try it, it may or may not work. That's because this method just calls the "ReplaceSelf" ability; so if an XNode doesn't have a "ReplaceSelf" ability, the "RemoveXnode" method will do nothing. So if you want your XNode to work with the "RemoveXNode" method, you must create a "ReplaceSelf" ability. Fortunately doing so is very trivial: Your ReplaceSelf ability only has to call the "GenerateCode" Ability; like this: Paul Cardinale P.S. Note that the "ReplaceSelf" ability of some NI Xnodes doesn't work properly. For instance if you call "RemoveXNode" on the "Match Regular Expression" function, it will make a mess, breaking the VI.

    Button text selection start end

    There's a similar (and probably related) bug when setting boolean text attributes manually: If you select a portion of the boolean text, then use the Font menu to change something (e.g. the color), it will change all of the text, not just the selected part. This bug showed up sometime around LV2008; it was fixed in one of the later versions; then it was un-fixed, and we still have it today. You can get around it by making floating text and setting it the way you want, then cut-and-paste into the boolean text. (I haven't tried programmatic cut-and-paste; maybe that would work.)

    Programmatically Set a Property Item

    I found it! Unfortunately it's deprecated. It takes dotted inputs as either names or ID codes.

    Programmatically Set a Property Item

    I want to set a property item in a Property node. For properties that have a single ID, I can get this method to work: For example, setting a property item for a Control property node to "Label" simply requires the ID string "6332005"; yielding: However many properties require more that one ID. For instance: requires "6332005" (Label), and "632d800" (text). I can't find a way to set a property item to a property that has such multiple levels. Does anyone know how to do this? Paul Cardinale

    Unrestricted Invoke Node.xnode

    Version 1.0.0

    13 downloads

    One of the difficulties with editing XNodes without the license is that invoke nodes for the XNode class don't show any methods. This XNode acts pretty much like a real Invoke node, but it allows access to all possible methods. You can also right-click and replace it with a real Invoke node.

    Placing an XNode on the Functions Palette

    I have determined that none of the existing abilities is called when the .xnode is placed on the palette. I'm guessing that either it needs another ability that I haven't got, or more likely, a property of an ability, or of the .xnode needs to be different.

    Convert Greyscale Image to False Color

    Something like this. Grayscale to False Color.vi
  11. I created a handy XNode and placed in on the Functions palette (the same way you place a .VI). The icon on the palette was the XNode's icon, and everything was OK. Later I added the "Help" ability; then the icon on the Functions palette became the icon of the "Help" ability VI. Furthermore, I could no longer place the XNode on a palette. Deleting the "Help" ability returns everything to normal. This happens with both LV 2017 & 2018. I haven't been able to figure out how to correct this. My guess is that there's something about my "Help" ability that's causing errors inside the Functions palette; but what? I thought maybe it was because I had an empty path in the Help cluster, but adding a path to a .html file didn't help. I know it's possible to place an XNode with help on the Functions palette, because you can to that with the Error Ring. I looked inside "Error Ring.xnode" and saw some items in there that weren't in my XNode; I tried adding equivalent items, but that didn't help. Does anyone have any ideas on how to fix this?

    XNode method AddLinkerReference

    Does anybody know how to use the AddLinkerReference method of an XNode? I'm trying to make an app specific XNode that will always live inside a Case Structure, and I want the XNode to be notified when there are changes to the Case Structure (specifically the Selector Label). This method (along with the OnRefeeChange ability) looks like it might be what I need, but I don't know how to use it. Any help would be appreciated.

    [CR] XNode Editor

    While using it, I decided I needed one more feature: Placing the XNode on the cursor so I could drop it on a BD. Here'e the latest version. XNode Editor.zip

    [CR] XNode Editor

    Here is the updated XNode editor. I hadn't logged into LAVA in such a long time that my old account didn't work anymore; so I created a new one. XNode Editor.zip
