Checkbox states

[OHE]

Hi everybody,

I would like to use in my software a behavior of the checkboxes and I don't know how to do it using LabWindows/CVI :

I Have a tree of options (the + symbol represents a checkbox):

+opt1

---+opt1.1

---+opt1.2

And if I check *ONLY* the opt1.2 element, I want the checkbox opt1 to be in the "undeterminate" state (you know, the green square on windows).

I could have use the dimmed property, but I also need to represent if my checkbox is interactible or not.

So how could I manage my code to have this behavior ?

I also triied to use the ActiveX control with the Microsoft Checkbox Windows Form (v2 because I'm using CVI9, but I hope I will have CVI2010 by the end of the week) but the "TripleState" property look like the dimmed one...

Any idea ?

Thanx a lot,

Olivier.
