I can change the formula in a formula node programmatically !

Just to let you guys now,

You can change the formula in a formula node programmatically.

I was looking into this because the "Eval formula node" is way to limited to do any real calculations.

Just have a look a this VI.

We use VI server to give the name of the VI in which you want the formula node to be changed.

Then VI server makes a link to the first formula node it finds in this Vi, an changes the formula

with the string you attached.

Really cool isn't it ?

cu,

Thomas.

Hi,

A remark : I also found out that you can't build a working executable from your VI if you use this trick...

That was expected. There is no way an executable can modify a VI.
