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]]> Thu, 15 Mar 2012 11:44:22 +0000 207 http://lavag.org/files/file/206-mercurial-provider/ Mercurial repository, from within the LabVIEW project environment.
This toolkit acts as an extension of the supplied LabVIEW SCC interface in LabVIEW professional.

The toolkit allows you to commit, push, tag changesets. Has support for adding Issue tracking IDs.]]> Sat, 25 Feb 2012 14:23:09 +0000 206 http://lavag.org/files/file/204-jgcode-preferences-dialog-library/ Open Source
The Library contains supporting VIs that integrate with the LabVIEW Preferences Dialog to simplify file IO using OpenG VIs.

Thanks to Yair/tst for help with refactoring

Installation locations:
\JGCODE\Preferences Page Dialog.vit - template for creating new pages
\JGCODE\preferences_dialog - example application and instructions

The following VIs are called dynamically so that linking is maintained:

\dialog\PreferencesDialog\PreferenceDialog.vi
\dialog\PreferencesDialog\optionsFrame_GetErrorReportQueue.vi
\dialog\PreferencesDialog\optionsFrame_GetPageReadyNotifier.vi
\dialog\PreferencesDialog\PreferencePages\SharedPrefPage_SubVIs\SetCursorBusy.vi
\dialog\PreferencesDialog\PreferencePages\SharedPrefPage_SubVIs\SetCursorNormal.vi
\dialog\PreferencesDialog\PreferencePages\SharedPrefPage_SubVIs\SetOkDisable.vi
\dialog\PreferencesDialog\PreferencePages\SharedPrefPage_SubVIs\SetOkEnable.vi
\dialog\PreferencesDialog\PreferencePages\SharedPrefPage_SubVIs\SetPanelCloseStateDisable.vi
\dialog\PreferencesDialog\PreferencePages\SharedPrefPage_SubVIs\SetPanelCloseStateEnable.vi

This Package depends on these other packages:
oglib_appcontrol >= 4.1.0.7
oglib_array >= 4.1.0.13
oglib_file >= 4.0.0.20

This package is Open Source

LVOOP Property Popper is a tool that aids in debugging Class Property Nodes.
Instructions:
* Open the LVOOP Property Popper UI
* Select a Class Property Node
* Press 'Get Properties'
* Double-click a property in the listbox to open that properties Block Diagram

Restart LabVIEW to refresh Menus after installation

Tools Menu:
Plugins can be found under Tools>>LAVA>>LVOOP Property Popper
'Run' - opens the LVOOP Property Popper UI
'Open Example' - demonstrates features of this tool

Installation Locations (relative to LabVIEW directory):

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.]]> Sat, 17 Dec 2011 19:06:54 +0000 200 http://lavag.org/files/file/199-state-machine-follower/ never fast enough).

The use-case I wrote this to improve is setting a Breakpoint on the Error wire coming out of the main Case Structure and probing the Case Selector terminal so I can float-probe wires during execution. The problem with this is that I had to manually select the current frame every time. This is boring, so I developed this plugin to automatically set the Visible Frame to the case most recently executed.

Use - Select the String wire connected to the main Case Structure's selector terminal, invoke the JKI RCF and select StateFollower.

Special thanks to - AristosQueue, for his help over here.

LabVIEW versions - tested in 2009 & 2011 - it should work in 2010 as well

Installation - use VIPM to install the VI Package

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.

into a single polymorphic vi which is a thin wrapper around the conventional
open, read, write, close and listener VIs for all the network interfaces.

It removes dependency on the underlying hardware transport protocol and provides
a uniform application interface enabling abstraction of the application from the interface.

Features:
Supports TCPIP, Bluetooth and UDP (p2p, broadcast and multicast) interfaces.
Supports encryption (blowfish).
Supports compression (zlib).

Installation:
Unzip to a directory of your choice.
Add the supplied .mnu file to your palette.

Required Packages:
Labview 9.0 or greater.
labview_blowfish_encryption library (included).

Known Issues.
None.

Versioning:
Current version 1.1.
