View File UI Tools UI Tools v1.4.0 Copyright © 2009-2016, François Normandin All rights reserved. Author:François Normandin Contact Info: Contact via PM on www.lavag.org LabVIEW Versions: Created and tested with LabVIEW 2012 Dependencies: OpenG Application Control Library >= 4.1.0.7 OpenG Array Library >= 4.1.1.14 OpenG File Library >= 4.0.1.22 OpenG LabVIEW Data Library >= 4.2.0.21 OpenG String Library >= 4.1.0.12 LAVA Palette >= 1.0.0.1 Description: This package contains tools for designing user interfaces. A first palette helps create special effects using transparency of front panel. Using them allows to quickly create fade-ins or outs using linear or exponential variation of the intensity. A second palette contains VIs to calculate the position of GObjects for many purposes like alignment, snap, mouse follow, etc. A third palette contains VIs to create dialog boxes based on class instances. "Simple Error Dialog" and "Simple Selection List" are featured with or without backrground blackening effect. A fourth palette includes some VIs to move objects programmatically on the front panel, using a basic deceleration algorithm to provide an impression of a smooth movement. The packaged VIs are all namespaced using a suffix “__lava_lib_ui_tools” which should not conflict with any of your own code. Includes: Front Panel Transparency (Fade In & Fade Out) Utilities (Alignment, Snap) Dialog (OOP based, extensible) Engine (Beta) for object movement Instructions: This package is distributed on the LabVIEW Tools Network (version 1.3) and updates are on LAVA (1.4). It can be installed directly in the addon folder of any LabVIEW version from 2012 to now. The addon installs automatically under the LAVA palette of the addon submenu.

The exclusive access of serial resources in VISA from different applications is not a VISA "feature" but a Windows OS feature. Once an application has a serial port driver open, Windows will under normal conditions not allow another application to open that port again. As to why there is a Lock and Unlock. You can have applications that communicate from different locations through the same communication port. VISA supports that but obviously it can not know about the communication protocol so if location A writes a command and then location B writes another command (to possibly a different subdevice on that communication link) it is random who will read the response to the A command and who will read the response to the B command. Resource locking solves that problem reliably in that A locks the resource, writes the command and receives the response before unlocking. Rolf Kalbermatter
