Issue Details

When I place a probe on the output wire of a cluster that contains an IMAQ Image Display Control, although I can create a probe, when I open the Probe Watch Window, it does not show any information and says "No Debug Info".

I am using LabVIEW 2023. Is it an expected behavior? If not, how can I fix it?

Solution

This is a bug in LabVIEW 2023. When you have an IMAQ Image Display Control inside a cluster and you probe this cluster, LabVIEW will not be able to show information in the Probe Watch Window.

As a workaround:
  • You can remove the IMAQ Image Display Control from the cluster and then you will be able to successfully probe the cluster.
  • If you want to probe the IMAQ Image Display Control, you can first unbundle it from the cluster, and then probe it. See below.

Note: "Internal 2" is just the name of my cluster here, your name can be different. Also, "ImageGUI" is the name of my IMAQ Image Display Control, yours can be different.
