Subvi with front panel terminal in a loop

[RyanWu]

Hi,

     I want a subVI to refresh a plot on front panel. I know how to do it in one VI, see example. But how do I do it with a main VI and a subVI? For example, I want the 'Microphone signal' and push button on main program.

Thanks,

Ryan

You pass a reference to those controls into the subVI from the main VI.  Inside the subVI, you connect those references to a Value property node.

Ravens,

     Could you give a sample?

Thanks,

Ryan

Here is a simple example on how to use references between a main and a sub vi.  Open the subvi first, then the main so that sub is in memory when main is opened.

hi tbob,

i have the same problem, but i can't open your files since i'm using labview 8.6. can you post them in a 8.6 version or as a screenshot?

I don't have 8.6, but here are the pictures:  Main is on the left, Subvi is on the right.
