OO control of sub class front panel controls

[davidpcl]

I'm just working on an application that consists of a top level class that spawns 2 Daemons that inherit from the top level class.

My problem is that I want to kill the daemons from the top level, and previously I've done this (not using LVOOP) by having a stop button on the front panels of the daemons and dynamically setting these to '1' using invoke nodes, however in my current app this isn't working - the child isn't lettting the parent press its buttons and all I kind think of is that is the contraints of LVOOP that are causing this.

Any thoughts or help very gratefully appreciated,

Hi David,

I'm not quite sure what you mean. Could you post your project so I could have a look at it? You can create a zip file of the project from the Build Specifications.

Hi John - I managed to resolve the problem - turned to be a case statement using a default ref value which should have been wired - schoolboy error really but as I'm fairly in-experienced with classes in LabVIEW my first thought was that it might that the class framework was not allowing a parent class access to controls of the front panel of a child class, but have found that is not the case which is consistent to my understanding of how the relationship should work.

I'm really enjoying the class features of 8.20 - has really enhanced LabVIEW a huge amount in my opinion - the only thing I'm worried about si what the sort of overhead the class functionality places on apps - I'm working in an environment where speed is everything - maybe I'll do a post about it or ask someone from NI Newbury about it.

Thanks for your response,
