XNodes in the Development Environment
XNodes can be added to palettes as if they were plain VIs; however, the icon
that is displayed in the palette is that stored in the .xnode file and not the image created by the Image Ability vi. It is possible to set the icon in the .xnode file by manually editing the xml file. One way of doing this is to create a LabVIEW library (.lvlib, not .llb) from within LabVIEW and edit the icon for this library. Then making sure that all references to the Xnode are closed, open both the .lvlib file and .xnode file in a text editor and copy across the <Property Name="NI.Lib.Icon"... line.
