object reference invalid

[WeberM]

Hello,

in my application I want to control numeric and string controls. I attached the vi's.

in another application this structure works with boolean controls.

i've got no idea to solve this problem.

thanks

Hi Markus,

only this vi can do nothing because all the references are invalid. Where do you call this vi? You have to insert valid references into you Cluster.

Hello Mike,

thanks for your answer.

I found the problem.

I have no valid refnum connected to the vi.

thanks

This is expected because the references in the cluster are not linked to any control/indicator. They return the default value which is 0. Put a probe to see what's going on. You must initialize every reference in the cluster by wiring the reference of the corresponding control/indicator of the front panel.
