The LapDog.Messaging framework has been updated to version 2.1. This release should be fully backwards compatible with version 2.0 while introducing a few new features to support unique developer needs. Improvements include: -Two new native message types supporting Double and Variant types. -A new companion library includes I32Array, DoubleArray, StringArray, 2dStringArray, PathArray, BooleanArray, and LVObjectArray messages. -A new type of queue, PrefixQueue, makes it easy to universally assign a prefix to all messages sent on a specific branch. This is useful when the message receiver needs to distinguish between identical messages from different senders. -The package includes a "Fundamentals" example illustrating some of the core concepts of the LD.M framework. (I have not prepared the example for the Example Finder yet, so use VIPM's info window to get to find it.) -VI documentation has been improved. All VIs on the palettes now include documentation. This package works with Labview 2009-2011. Go here to download the latest release and give it a try. -Dave

A friend pointed me to a website dedicated to restoring rare words to common usage. The site randomly picks a word for each visitor to popularize. I got two, and both of them are excellent choices for me since I have a use for both of them. The one that I encourage LabVIEW users to adopt is: primifluous: that which flows first. As in: "The primifluous wines were excellent." For LabVIEW and dataflow, the usage is obvious: "The primifluous nodes initialize the hardware." "Perhaps you should make that assertion primifluous.""FP Terminals are primifluous unless placed inside a structure node." (The other word, in case you're interested, is "nidifice", and older term for an eagle's nest. Pronounced with "nigh" at the beginning and rhymes with "edifice". Given that NI's mascot is Nigel the Eagle, and that this term begins with "ni", I will henceforth refer to NI headquarters building as The Nidifice.)

I've not come accross Quad-tree but I have come accross R-Tree

Or, as I suggested in the Idea Exchange, simply color your Front Panel black.

The pluginArchitecture.zip posted by Paul earlier in this thread belongs to me; and I admit, I botched it. I recently fixed it up and created a step-by-step presentation on how it is done. Find it all here: https://decibel.ni.com/content/docs/DOC-19176
