Set Busy cursor does not work for a VI that is dynamically run

[Bruno Paillard]

The cursor functions (Set busy and unset busy) usually work well when they are used in a VI that is statically run (either a top VI or a VI called from within a VI).

However, when they are used in a VI that is openned and run dynamically (using the VI server) I get an error message:

LabVIEW:  Null window.
=========================
NI-488:  Wait in progress on specified input handle.

How can I solve this problem?

I'm not sure why that would happen, but if you could post a small set of VIs that demonstrates this, I'd be interested helping figure out why this is happening.

As a workaround, you might try explicitly wiring a VI reference for the VI for whose panel you want the cursor to go busy into the Set Busy VI.

Good luck!

Hello Jeff

I have just talked to the support people. This is a recognized bug and will be corrected in the next release. They said there is no workaround at this time.

Thank you for your help.

Regards

Bruno

G Toolbox ($) can set cursor style, long before NI implemented this feature in LabVIEW.
