PW.zip(LV5.1)
This tool can be used when you've forgotten the password of your locked VIs. You can choose what set of characters to use, and even use a dictionary file if you think your password contains real words. A few dictionary files can be found here, or you can supply your own. This tool also remembers it's last state with an INI file. Have fun, and do share your success stories.

Resizable File Manager  Hot Tool (LV 5.1) The File Manager that comes with LabVIEW (found on the Project menu) is useful, but I often find that the listbox controls are too small to show the full filename, especially when Show Dates is turned on. I also wanted to see more files displayed at one time. So I used some tools I had created for other projects to make the window infinitely resizable. This is a good example of how to make your windows resizable. Note that this does NOT use the new LV 5.1 Scale Objects feature. My methods give you much more control. Hint 1: Put this LLB in the Project folder and restart LV. Resizable File Manager will now appear in the Project menu. Hint 2: Since it runs automatically, to examine the code, hit ctrl-<period>. The resizable stuff is at the bottom. Note: If LabVIEW asks you to find Manage User Action.vi or any other VIs in llbedit.llb, this library came with LabVIEW and should already be in your Project folder. Otherwise, you can download it here. |

Find VI Password (LV 5.1) This tool can be used when you've forgotten the password of your locked VIs. You can choose what set of characters to use, and even use a dictionary file if you think your password contains real words. A few dictionary files can be found here, or you can supply your own. This tool also remembers it's last state with an INI file. Have fun, and do share your success stories. |

A Millennium Wish.llb (LV 5.1) A Millennium Wish.zip (LV 5.1) For the New Millennium, Jean-Pierre Drolet has programmed a short animation made mostly with LabVIEW objects. In this gift to the LabVIEW Community, are some neat programming tricks, which can be useful for other projects. Included in Goodies.vi are some controls and decorations that might also be useful. |

Get Flattened Pixmap (LV 5.1) The Picture Control Toolkit is now included with LabVIEW 5.1. It now includes VIs for Reading and Writing JPEG, PNG and BMP files. Also included with LV 5.1 is Draw Flattened Pixmap.vi, which one can connect to Read JPEG File.vi, et al., and get the contents of the file output to a picture indicator. But there's no way I could find for saving the contents of a picture control to a file. Oh sure, there's Write JPEG File.vi. But it wants flattened image data and color table as inputs. That's where Get Flattened Pixmap comes in. It takes a picture control and converts it to the proper data structures to wire to Write JPEG File.vi, et al. |

Picture To File (LV 5.1) Created by Robert Erfling, here's a more complete set of VIs to save a picture created with the Picture Control Toolkit. Just wire this thing up in your VI, and it will put up a file dialog, convert the picture as needed, and save it. |

Scroll Text (LV 5.1) Here's a VI that I created to make text scroll smoothly on my About screen. It repeatedly draws the text to slightly different offsets within a picture indicator. This gives the illusion of movement. Note: Requires Picture Control Toolkit (included in LV 5.1) |

Progress Bar (LV 5.0) This VI and associated subVIs provide a professional looking progress bar complete with elapsed time and estimated time remaining indicators. It runs in parallel with your timed process and acts like the LabVIEW load progress window in that it only shows up after the timed process has been running for more than a second AND there is more than a second remaining. That way it doesn't flash needlessly if the timed process completes quickly. Also includes Number to Time String that formats a quantity of seconds into a hh:mm:ss.s string, including logic to only show required portion. Thus, 3602.34 seconds will show 1:00:02.34 but 101.5 seconds will only show 1:41.5 |

Changed (LV 5.0) This collection of VIs make it easy to detect when a front panel control has changed, without using a lot of diagram real estate. Simply wire your control to the input of one of these VIs, and the output will tell you if the value has changed or not since the last iteration. These VIs are re-entrant so they can be used in multiple locations. Tip: You can make change detection VIs for other types, including clusters and arrays by duplicating one of these VIs, and changing the front panel control. |

Draw Sideways String (LV 3.1) Draw Sideways String (LV 5.0 and Windows NT) This was published in the Winter 1996 issue of the LabVIEW Technical Resource. This VI will draw a string sideways, just like in the icon at left. Read the LTR article here (shift-click on the link to download it). Note: Requires Picture Control Toolkit (included in LV 5.1) |

Increment (LV 5.0) Ever want to change the Data Range (min, max, and increment) of a control programmatically? Unfortunately LabVIEW won't let you do that, but with this little subVI, you can work around that annoying omission. Simply drop the included numeric control with no arrow buttons, and then drop the two included arrow buttons next to it. Wire it all up to the subVI and your users will never know the difference between it and the original. |
