Class control greyed out

[Intaris]

Really stupid question: Is the Control disabled on the FP?

Right-click - Advanced - Enabled State   ?

It doesn't like that game

Ah. Because you have data there which isn't the default class data, it may actually be of a child instance which is no longer in memory. But surely that would prompt for loading the child on loading the VI? I dunno. LabVIEW is weird sometimes.

Can you throw a probe on it an run it to see what it's defaulting to? Like Intaris said, maybe it's a child class. Maybe the probe will show some more info?

If you first make the class control a TypeDef then you can enable or disable it from that menu.  If you then immediately Disconnect it from the TypeDef you are stuck in the enabled/disabled state that you set.

I think this is an interesting thought. Looking at the class, this code is extended by a child. In the application it's always the child on the wire (it just does its bit then calls parent).

I wanted to check the theory, but attempting to run it went badly. Complete IDE crash : DAbort 0x0037C03D in MemoryManager.cpp

I'm thinking I should just replace these and move on with my life. Unless anyone else has any further insight.

I had no issue setting child class data as default and then completely nuking the child class.  No errors, no problems.  The data is sliced as expected.

The only way I can get grayed out class controls with an unbroken VI is by disabling.  This can be done by making the control a typedef temporarily, using the Property Node, or using the Properties dialog.  If you right-click the control and select Properties does it show as Disabled and grayed out?

Darin, properties for this one shows enabled.

Edit: Interestingly, if I set it to disabled and grayed, it gets grayer.

Here "in" is disabled and grayed

Kill them all and move on before they corrupt more of your code...

Thanks for all the suggestions. I think I will follow Darin's advice and burn them with fire.
