Triple buffer
By CharlesB
(initial discussion, with other implementations here)
In the need for displaying large images at a high performance, I wanted to use triple buffering in my program. This type of acquisition allows to acquire large data in buffers, and have it used without copying images back and forth between producer and consumer.
This way consumer thread doesn't wait if a buffer is ready, and producer works at max speed because it never waits or copy any data.
If the consumer makes the request when a buffer is ready, it is atomically turned into a "lock" state. If a buffer isn't ready, it waits for it, atomically lock it when it is ready.
This class allows to have a producer loop running at its own rate, independently from the consumer. It is useful in the case of a fast producer faster than the consumer, where the consumer doesn't need to process all the data (like a display).
How to use
Buffers are provided at initialization, through refnums. They can be DVRs, or IMAQ refnums, or any pointer to some memory area.
Once initialized, consumer gets the refnums with "get latest or wait". The refnum given is locked and guaranteed to stay uncorrupted from the producer loop. If new data has been produced between two consumer calls, the call doesn't wait for new data, and returns the latest one. If not, it waits for the next data.
At each producer iteration, producer starts with a "reserve data", which returns the refnum in which to fill. Once data is ready, it calls "reserved data is ready". These two calls never wait, so producer is always running at a fastest pace.
Implementation details
A condition variable is shared between producer and consumer. This variable is a cluster holding indexes "locked", "grabbing", and "ready". The condition variable has a mechanism that allows to acquire mutex access to the cluster, and atomically release it and wait. When the variable is signaled by the producer, the mutex is re-acquired by the consumer. This guarantees that the consumer that the variable isn't accessed by producer between end of consumer wait and lock by consumer.

SET Localization Toolkit
By Porter
The SET Localization Toolkit provides more convenient edit-time language switching support for LabVIEW 2013 projects.
UI text is extracted from an existing project and stored in a localization file. Additional languages can be added then applied to the project using the apply language wizard.
The idea is to be able to quickly apply a language to a project before distribution. Applying the language at edit-time allows you to fix up the UI in the target language. Change fonts and re-size controls so that it looks right before compiling it.
Features:
- No modification of project's source code required. No additional dependencies.
- Support for switching code pages.
- Ability to define shared resources.
- Resources referenced via UID. Changing labels of control does not break linkage.
- Resources can be exported to CSV file for external translation.
- Resources stored as UTF-16LE text.
- Ability to translate RTM files.
Requirements:
- Unicode support enabled in the LabVIEW.ini file
Installation:
- Download the ".vip" file and install using VI Package Manager 2014
- Make sure that "UseUnicode=True" is set in the "labview.ini" file
Usage:
- From within any LabVIEW window, select "Tools->LAVA->SET Project Editor"

ShapeLib
By SDietrich
This is a package containing LabVIEW bindings to the library ShapeLib for working with shapefiles.
The DLL as of version 1.3.0 is included in the package. This DLL is compiled with Microsoft Visual Studio 2010 Express, so you need the corresponding runtime. But chances are you already have it because other programs on your computer need it, too. So just give it a try.
The library is thread safe, but the objects are not. E.g. you can open two different files in different threads, but you can not operate on the same file from two different threads at the same time.
As of the moment the DLL is 32bit only.

Bluetooth Connect and Event Monitoring
This VI can Discover, Pair, or Remove Bluetooth Device. Can Connect or Disconnect (no data socket enabled yet), Can establish a Comm Port, Open the Comm Port, Close A Comm port.
Has the machinery but needs debugging for the Windows bluetooth Event Monitoring. Any help would be VERY VERY WELCOME.
I'm uploading this because I really wish somebody else had uploaded the necessary code for bluetooth pairing, but at the moment wish somebody else had uploaded code for monitoring bluetooth events (connect or disconnect events)

easy increment
By tylertroy
I have always found it frustrating that I cannot efficiently change numerical values with the mouse only. This is especially true when I'm simultaneously looking at a gauge on the other side of the room and changing values with my wireless mouse.
"easy increment" selects individual decimal place values by moving the mouse across the spacial extent of a numerical control. Mouse wheel scrolling may then be used to to modify these values.
It's easier to use than explain, I promise!

Rubiks Cube Solver
By Neil Pate
This project is a 100% G based Rubiks Cube solver that I coded quite a while ago (2007) and then forgot about. I must have saved it it more recently in LV2011.
The algorithm is based on the 7-step method, which is totally sub-optimal for solving a cube, but relatively simple to understand.
Please note this code is not representative of my current coding ability, I just upload it in case anybody is interested.
If I get time I would like to do a 3D representation of the cube and allow the manipulations to be done in this view.
Run instructions:
set the show boolean to True click randomise! pick a start colour click solve! The buttons on the left hand side can be used to do manual manipulations of the cube.

Wire And Connect Quick Drop Plugin
By bbean
This Quick Drop (QD) plugin complements the functionality of the built-in QD plugin (CTL-Space-CTL-D) by wiring between selected controls, indicators, constants, and SubVIs.
Default Shortcut - [W] Normal Operation Wires selected nodes in left to right order. Attempts to connect any common unwired terminals in between the far left and right nodes by checking the datatype, Name, or Caption. Holding Shift and the Shortuct: Wires controls to unwired far left Node terminals and indicators to unwired far right node terminals. This is just something I put together as my first attempt at a Quick Drop plugin. Something similar has been done previously to wire the corners of subVIs using the right click framework by user JCC_(SK): RCF Plugin - Wire Nodes by Corner - https://decibel.ni.com/content/docs/DOC-8386 . Code for this plugin was developed prior to knowledge of the JCC_(SK) RCF code and probably doesn't function as well since it hasn't been tested thoroughly. However this plugin is for quick drop and has some added capability to wire up all like terminals but can suffer from potential overzealous wiring. Just delete extra wires if necessary. Thanks to the NI guys for creating the QD template with good instructions. Someone may have done this already but I'm putting this out for comment anyway. <a href="http://www.screencast.com/t/PZhMafM2">WireAndConnectVideo</a> http://www.screencast.com/t/PZhMafM2

Data Broadcasting Library for Actor Framework
By Stobber
Use v1.0.0 for LabVIEW 2011-2012.
Use v1.1.0 for LabVIEW 2013+.
The attached library provides extensions to the Actor Framework to facilitate the broadcast of messages from one actor to several others. Listeners subscribe to a message when they want to receive it from the Broadcaster, and they unsubscribe when they want to stop receiving it. The library provides a set of common interfaces that decouple Broadcasters from Listeners so any two actors in a messaging hierarchy can communicate via broadcast without having the same caller.
This library extends the Actor Framework; it does not modify the core framework in any way, so it may be used in existing projects as well as new ones.
Documentation for the library and the included example program is attached.

Toolbar XControl
By gb119
lavag_lib_User_Interface_XControls_Toolbar XControl v1.0.0.3 by University of Leeds
Author: Gavin Burnell
Copyright: Copyright © 2013, University of Leeds
License: BSD
Compatible LabVIEW Versions: >= 2012.
Compatible OS Versions: ALL.
Description:
This is a native toolbar for LabVIEW implemented as an XControl. It supports a single row of square buttons which maybe latching (sticky) or transitory (command) style buttons drawn in one of 4 different styles (system, square, flat or rounded). The toolbar will report button clicks via a value change event, but allows the possibility for further integration into other messaging systems.
The buttons are represented as instances of a button base class that provides methods for drawing the button, updating tooltip text or responding to clicks. Overriding these methods in subclasses allows a greate flexibility of response. Included in the package is a 'vi-button' class that stores a vi reference with each button and executes it when clicked.
This Package depends on these other packages:

GPower toolsets package
This is a submission for the GPower toolsets palette, which will also shortly be available on the NI LabVIEW Tools Network. I submit it to Lava to (of course) share it with everyone, but also to establish an open forum to discuss improvements and to provide support. Much better than hiding all this in private email conversations with each user.
The toolsets are compiled for LV2009 SP1, are provided as VIPs for VIPM, and will mass compile to at least LV2010 and LV 2011 without problems (this happens automagically during the VIP-install process for those of you that don't know VI Package Manager ). The 'gpower_lib_toolsets-1.0.0.6.vip' is an umbrella for the four other VIPs, it doesn't add anything extra by itself.
Currently this consists of 4 toolsets:
Dynamic Dispatch
Open, pass data to (without using the front panel), run, and close dynamic VIs. A cumbersome process using VI Server made easy with this toolset.
Error
Streamline common error wire tasks such as set, filter and clear errors and warnings, and unbundle the error cluster. Adds advanced features such as dynamic setting of custom global errors, that you can invoke from anywhere in your application, and bundling errors into a single error wire. No more need for arrays of error clusters!
Timing
Calculate elapsed and remaining time, and abort a running Wait function for instance.
VIRegister
High performance "global variables" that lets you pass data between any corners of your application. It's based on queues, so a "global" that does not involve using front panel controls, files, or the LV project - it all happens in the block diagram. In most cases you don't even have to pass a refnum around, just drop a VIRegister somewhere and you're done.
If this thread generates too much noise across the different toolsets, we could split this into 4 submissions. But lets see how it goes. More toolsets are awaiting release, but I'll start with these four to get a feel for the process.
Cheers,
Steen

Multiple File Path Control
By David_L
This Multiple File Path Control is similar to the default File Path Control in LabVIEW 2011, however you can select more than one file at a time. The data type on the block diagram is an array of File Path Control.
Right click on the MFPC to have it display the full paths or just the file names.
I'll try to post this in pre-2011 but because it uses silver controls, I'll have to make some significant changes.

HTML Report Embedded images
By Ton Plomp
This class adds a special version for the HTML-report generation VIs.
By using this class you can use the normal report generation functions, however images will be embedded in the HTML file inside the <IMG> tag.
This tool adds a special override class for the Report Generation toolkit. With this class come 3 overrides for the following functions:
Append Control Image to report
Append Image to report (path)
Append Image to report (string)
These functions allow you to embed the added image into the HTML IMG tag. With this functionality it's possible to generate HTML reports that can be shipped without depending on a file-layout or web-server.
The included DEMO VI shows you how to use this class (only the initiate function is required), and loads a sample file into your default web-browser.

Encryption
By Ton Plomp
This package consist of a series of tools in native LabVIEW 2010 code.
For encryption/decription the AES (Rijndael) routine is used with key sizes of 128, 192 and 256 bytes.
The encryption supports the following block modes:
EBC
CBC
CFB128
OFB
For signing of string/packages it performs the SHA-1 and SHA-2 hashing, for MD5 hashing the OpenG functionality is used.
The hash functions return a binary string and a hex-formatted string with the hash.
The following hashes are supported:
MD5 (via OpenG library)
SHA1
SHA-2 224 bit
SHA-2 256 bit
SHA-2 384 bit
SHA-2 512 bit
For Hashed key authentication the HMAC functionality is provided based on the supported hash functions.
The used functions are tested against NIST public test vectors.
The use of these functions is not: secure the code does not try to protect it's memory nor the used keys.

CheckIn.vi
====================
This VI will attempt to checkoutin a ClearCase Object (file or folder).
uses ClearTool --- uncheck/out | unco [ –kee/p | –rm ] { –cact [ pname ... ] | pname ... }
–kee/p
Preserves the contents of the checked-out version under a file-name of the form element-name.keep (or, to prevent name collisions, element-name.keep.1, element-name.keep.2, and so on).
–rm
Does not preserve the contents of the checked-out version. Thus, any edits that had been made to the checked-out version are lost.
NOTE. Error -2904 if files in not checked out

CheckOut.vi
=================
This VI will attempt to checkout a ClearCase object (FIle or Folder).
INPUTS
----------
FileName & Path itme to be checked out can be file or floder
Checkout comment A checkout comment
checkout Type see below
CC Branch A optional branch to checkout on e.g \main \main\dev\ats\111 see below
uses ClearTool

| –nc/omment ][ –q/uery | –nq/uery |–use/hijack ] pname ...
–res/erved
Reserves the branch: no user in another view can perform a reserved checkout of the same branch (but any number of unreserved checkouts can be performed); no new versions can be created on the branch until your checkout is changed to unreserved with unreserve or resolved with checkin or uncheckout. If you specify both –reserved and –unreserved, this command performs a reserved checkout if possible; otherwise, an unreserved checkout.
–unr/eserved [ –nma/ster ]
Leaves the branch unreserved; other users, in other views, can check out the same version (but at most one of the checkouts can be reserved).
CC BRANCH
Default - blank. View Config specifications rules will be applied.
This allows a specific branch to be used to be used to checkout the file. NOTE branch must in this case MUST be the full branch path ie \main\dev-ats-456 not the branch type dev-ats-456. If CC Branch is used the CC warning messages are suppresed as they WILL occurs, but do not indicated we have have a problem, the branch used MUST EXISTS for the objects being checked out
