Type Sensitive Popup

--see readme file for contact information.
Description:
Provides an intuitive interface for tabular controls containing multiple data types. Users can use various controls and datatypes. Users can also use provided functions for registering and looking up type parameters by control (as well as by column, row, or cell).
When you click on a cell, a correctly positioned and sized popup appears allowing for a controlled and intuitive input. Appears like it is a built-in feature, not an annoying popup window.
Features:
- Supports tables, listboxes, multicolumn listboxes, trees, and string controls.
- Implements many data types : string, integer, float, color, ring, boolean, captioned string, etc.
- Can use multiple tabular controls in same program with no programming changes
- Can pre-register controls with certain data types
- Register the entire control, or columns, rows, and cells.
- Can edit the registered data type by registering again at any time
- Allows for different font sizes
- Works even on modal windows
Instructions:
Run the Demo program to see example usage.
To recreate --
1. Drop 'TSPopup.Popup Cluster.ctl' anywhere on your front panel.
2. Create program logic, similar to the demo
MANDATORY elements
a. TSPopup.Initialize.vi (register for the user event in your event structure)
b. TSPopup.Lookup.vi (returns positioning information, looks up any registered controls)
c. TSPopup.Show Popup.vi (called in a Mouse Down? event case)
d. an event case for the user event output from (a.)
e. TSPopup.Close.vi (called at end of program)
OPTIONAL elements
f. TSPopup.Register.vi (register controls with popup type parameters)
g. TSPopup.Update Cell String.vi (provided to show how to change the cell string after popup is completed)
3. Bring the Popup Cluster to the front on the front panel. Otherwise the popup will show up behind some of the other controls on your User Interface.
Limitations:
- Can't programmatically bring popup cluster to front. Must do this manually.
Change Log:
1.0.0: Initial release of the code.
1.0.1: Added another demo using dynamically changing data types in a tree
Removed LV version specific event handling (only dealt with LV 7.1)
Fixed bug where headers defaulted to have same type as their column/row
Fixed cluster scanning from text
Fixed ring to default to index 0 if string unrecognized
Changed the background event monitor to always be hidden

GetClipboardData.vi retrieves image, text or a file/folder selection and puts the data into a corresponding control.
Dependancies:
Labview 8.0.x or higher
Windows operating system (tested with XP)
Uses user32.dll, Kernel32.dll and shell32.dll (usually found in C:\windows\system32 folder)

Get Reference To All Controls
Copyright © 2007, GTech Automation
All rights reserved.
Author:
Dave A. Graybeal
--see readme text for contact information
Instructions:
This code has been tested to run under LabVIEW 8.2.1. Unzip the code into any folder of your choice and open the example called, GetRefExample.vi. This shows how to use the 'Get Reference To All Controls.vi' as well as the 'Get Control Reference by Name.vi' to obtain a reference to all controls and how to search thru those reference to obtain the reference you want.
Features:
Get Reference to All Controls.vi
-Gets the references and labels to All the controls on the front panel of the calling VI.
-Is Able to search thru all Tab Controls recursively to compile a complete list of Controls from the front panel.
Get Control Reference by Name.vi
-Polymorphic VI that allows for searching list for single reference or an array of references.
-Gets a Specific Reference from the List of All Controls by Control Name(Label).
Get Control References By Match Pattern.vi
-Gets an Array of References for all Controls containing the regular expression in the label.
Change Log:
1.0.0: Initial release of the code.
1.1.0: Changed the Class ID of a Tab Control from a constant to a Property Node (To support Future LabVIEW Releases)
1.2.0: Added Get Control References By Match Pattern.vi (Authored By: Justin Goeres) Thanks!
Modified GetRefExample to Include the Get Control References By Match Pattern.vi
Improved some performace by removing unnecessary Items from Loops (Thanks JFM!)
Removed all Dialog boxes from VI's and replaced them with proper error output messages.
Added shift registers where necessary to ensure proper error is passed out of each VI.
Recompiled under LabVIEW 8.2.1.

--see readme file for contact information
Description:
Package to provide smart tree functionality without assumption of type of data (ie, file paths or others)
Gives ability to modify contents, extract information and control the branches.
A good understanding of how the LV tree truly operates as a fancy multi-column listbox is very useful although not required.
An expample program if not present on the forums, will be in place soon.
Dependancies:
LV version above base package
Functions
Add Item
Modify Item
Remove Item
Get All Items
Get Top Level Items
Get Items Parent
Get Selected Item
Get Siblings
Get Children
Get Item Properties
Check Tag Valid
Convert Tag to Text
Find Tag from Text
Outdent at Item
Indent At Item
Expand
Collapse
Empty Tree
Notes
Capable of working w/ LV 7 or later but uploaded version is for LV 8.2. Please request previous version if necessary.
Good to recognize that the tree control is just a fancy multi-column listbox.

Picture Hacks

Author:

--see readme file for contact information
Description:
A couple of Picture datatype hacks to illustrate the structure of the (LV 6.1 - LV 7+ is untested) picture control.
-- Main VIs --
Example - Show How Picture Is Made.vi:
Main example, shows (incrementally) how a specific picture is generated by displaying the picture with each packet
incrementally added. Good way to see how your own pictures display information.
Opcodes.csv:
Comma-delimited file explicitly describing the packet types and their requirements / uses.
Tool - Picture concat.vi:
Given two pictures, concatenates the data to create a single overlapped picture.
Tool - Packets to Picture.vi:
Given an array of picture packets (cluster), generates a picture.
Tool - Picture to Packets.vi:
Given a picture, generates an array of picture packets.
-- Utility subVIs --
sub - 8-Bit string to 32-Bit number.vi:
utility VI to cast a string to a 32-bit number. Typecast might work instead but this is more explicit.
sub - Find Opcode:
Given a picture data string that has the size header removed, this will extract an opcode from the front.
sub - Strip top of and check picture.vi:
Utility VI to strip the header (size) from a picture data string so that it can be scanned for packets.
Change Log:
1.0.1: (11/13/06)
Cleaned up code for LAVA requirements:
- Renamed VIs for clarification of purpose
- Fixed coercion dots
- Added 0ms delays in all loops
- Added error encapsulation in some subvis
- Replaced local variable for cluster to constant in order to limit thread swapping between the user interface and code threads
1.0.0: (11/07/06)
Cleaned up code from 6i 2001 version for submission.

JKI Progress Bar Dialog

All rights reserved.
Author:
Michael Aivaliotis
Instructions:
This code has been tested to run under LabVIEW 7.1.1. It will probably work on any newer versions but it has not been tested. Just unzip the code into any folder of your chosing and open the example called, JKI PBD Example.vi. This shows a typical use case where you want to pop-up a non-blocking dialog within a process loop and display a message and updated text from a parallel running task. In addition, you can pass a max value and updated progress value and the dialog will automatically present a percentage complete progress bar.
Features:
- Contains an abort button on the dialog that can assist in aborting a running process.
- You only need to pass the total number of tasks\items and the dialog automatically calculates percent complete.
- Can specify a limited preset amount of progress images via the "animation" selector
- Can update the status messages and progress in real-time after the dialog has been launched.
- Setting an animation value of 0 disables animation and displays only text.
- Handles being built into an application
- The dialog is not modal when run in the development environment however it becomes modal when built into an executable.

Description:
This library gives similar functionality as Three Button Dialog.vi but with some extra goodies.
It doesn't strictly conform to the guidlines for a dialog box, instead it shows my personal preferences.
CLL (Common LabVIEW Library) is my way of tagging VIs that have made it into my library of reusable code.
Version History:
1.0.0:
Initial release of the code
1.0.1:
Added version info to the description of CLL Dialog.vi
Changed some default values for TEST CLL Dialog.vi
