programmically entering event structure

[rpolson]

Hi-
I want to use an event stucture to calcuate some things when values on the front panel are changed.  It works well and as expected.

How do I force the calculation to occur when the vi is first run?  I've tried initally setting a value to try and force a change of value, but I can't seem to make it work.
Attached is a very simple example.

Thanks,
Randy

Use the 'value signalling' property.
This will force the event to react as it would be on a 'value change'

Value signalling is incompatible with the latching action of the boolean. To use TonP's suggestion you will need to go back to the standard switch action for the calculate button. If you want to emulate the latching action you could use a local variable to set the value back to false after it was read.

Ah, value signaling property.  I didn't know what that property was before, now I do.
Thanks.

Lynn is right

To my defense, I didn't open the code because I had the feeling Randy was looking for the Value signaling property.

On a side node, why a property and not a method?
