Creating expandable nodes?

[1984]

Hi,

just for curiosity... is there a way to create VIs with expandable number of inputs such as for example the format into string or the concatenate strings nodes? If so how?

thx!

I've seen this question a few times on the forum, but so far there isn't a solution.  But that was a while ago.  Maybe someone has something new to tell us?

Hi,

Develop your own XNode:

- XNode Wiki: https://labviewwiki.org/wiki/XNodes

- More learning: http://vishots.com/xnodes/

- Example XNodes: https://lavag.org/files/category/10-xnodes/

- XNode Editor by Hooovahh: https://lavag.org/files/file/293-xnode-editor/

However this is very hard to fully develop and test an XNode, so putting one you developed yourself in production code is at your own risk.

Also, you won't get any support from NI as it is an unsupported technology.

There is also a limitation that makes the XNodes not inlineable, meaning you cannot place an XNode directly in a VI marked as "inline", including malleable VIs.

Regards,

Raphaël.

Not only are XNodes challenging to build, but they are dangerous.  Small mistakes can lead to big havoc.
