Editing VI Documentation with Icon Editor (for LV12)

With this modified and new VIs, the VI documentation can be edited in a separate tab page in the Icon Editor. I hope this will motivate writing documentation for your VIs.

Known limitations

  • Undo and Redo leave out the documentation elements
    • At least it does this consequently


  • open the LabVIEW directory "%Program%/National Instruments/LabVIEW 2012/resources/plugins"
  • (optional) backup the original file "lv_icon.lvlibp" by moving it into a new directory ("lv_icon_orig/"):
  • extract the file in the zip file "lv_icon packed *.zip" in the directory
  • The modified Icon Editor should pop up now when you edit a VI in LabVIEW 2012

If this does not work do the Installation for Development (see below)

Installation for Development

  • Install the source of the Icon Editor as described here: Icon Editor Source Code for LabVIEW 2012
  • open the LabVIEW directory "%Program%/National Instruments/LabVIEW 2012"
  • (optional) backup the original files by moving this files into a new directory ("lv_icon_orig/"): 
    • "lv_icon.vi", "lv_icon.lvproj", "NIIconEditor/Controls/References Cluster.ctl",  "NIIconEditor/Miscellaneous/Menubar/ShowLayersPalette.vi"
  • extract the files in this zip file in the LabVIEW directory ("%Program%/National Instruments/LabVIEW 2012") 
    • This wil place some files in "resources/plugins/".
    • only the files mentioned to backup are overwritten
  • The LabVIEW Project containing the Icon Editor VIs is this one: "resources/plugins/lv_icon.lvproj"
