A collection of packages with useful functions. I am also using these professinally at work for the Belgian company CIT.

Most of these files have been written in or converted back to LabVIEW 6.1 as this version is still in use at a lot of sites and any new version of LabVIEW can open them anyway.

• Split string at delimiter, just like in perl
• Join strings with a delimiter (inverse of above)
• Chop string into equally sized parts
• Split arguments (for example for a Unix-like command line)
• Convert special chars to backslash codes (for example: Carriage return to "\r") and v.v.
• Multiply string, creates a string containing n given characters. (Now made to look like Initialize array)
• Find and replace regular expression
• Extended regular expression match, which understands brackets and pipe symbol
• and some more.

• Select elements from array: DBL, I32, string, path. Why? See this page.
• Delete values from array: DBL, I32, string, path
• Unique values in array: DBL, I32, string, path.
• Duplicate search 1D string array
• Replace string array element and autoresize.
• Duplicate search 1D string array

• Write to file, optionally appending
• Read entire file
• Application root, determines the location of the toplevel VI
• Make absolute path
• Make relative path (if possible)
• Find common part in an array of paths
• Determine if a path is within an other path
• Move and Copy with replace
• Create dirs (given dir and its parents)
• Get hostname
• Standard ini file name (in root of your app, optionally with username and hostname)

• Convert LabVIEW time values to a string
• Scan a string using a given time format (identical to the format strings of Format Date/Time string).
• Interpret a freeform time string.
• Handle time zones. Recognizes timezones like CET, PST etc. LabVIEW's internal time value is UTC (Universal Time Coordinated, an absolute time that uniquely identifies a point in time), but LabVIEW's presentation is dependent on local settings. Use this package to format and scan time values in UTC so that they are independent of regional settings and daylight saving.
• Converts to/from Excel (Note: an earlier version (20041223) was wrong! Fixed)
• Converts to/from Unix/Linux
• Converts to/from Julian day

If you have once programmed filling an NI Tree control, you know how cumbersome that is. This package offers a function to fill the tree with itemstring just like a multicolumn listbox. No more hassle with invoke nodes and property nodes, this is real dataflow, fully in the spirit of LabVIEW. The tree's structure is determined by an array with indentation values. There is an example that shows the use of some available functions, but for normal operation you only need the "set itemstrings" function.

If you find a bug, please let me know. If you like the VI, let me know as well :) When you get error 16, you have run into a bug of the Tree control itself. To get around it, I think you need to fill the tree with something before you run it the first time.

It's called "spring" because it causes leafs to grow on the tree.

CrystalFontz is a company that makes LCD devices. For PCs they have USB and serial LCDs. These devices are ideal for situations where there is no space for a PC monitor and keyboard. The CFontzVIEW driver can control the LCD device by writing text to it, setting the general purpose outputs and leds, and reading keypresses.

This driver supports the 631 and 635 USB displays, and the 633 serial display. These devices use the CrystalFontz packet protocol.

The driver is released under the Lesser GPL 2.1. The license is included in the file "README - licence.txt" and you can also read it online here.

Please inform me of any bugs you may find.
