How to edit/enter the expression in an expression Node via VI scripting?

[Dr.Polz.Photonics]

Hey folks,

I am working on some VI scripting and stumbled upon the following issue. I can create an expression node with VI scripting without any problems, but I am unable to find a proper method/property to supply the actual expression to calculate something. Some hints would be appreciated.

Cheers.

Why are you trying to change the expression on the fly?  Maybe there's an easier way to accomplish what you had in mind.
