Numeric data change simultaneously when being modified in dll.

[neoelfish]

Hi all.

Numeric data change simultaneously when being modified in dll. Do not have to read it. Just like transmiting reference to subVI.

Any way to achieve this? 

Thanks.

what do you really mean?

change the numeric data in the front panel but not affect the data in the dll?

or other meaning?

I mean how can I achieve this:

    Call dll, data will be modified in dll at sometime(do not know when). When data change, it's new value can show in the front panel without actively query

Depends. LabVIEW is dataflow. There needs to be a wire somewhere getting the data and feeding it to the control or local.

You could post the new value to a shared variable and connect it to the control though.

I agree with the option above~
