Events on elements of cluster

Question

Hi,
I have a cluster with 500 boolean controls (week-calender).
I want to detect some events on these boolean controls :
- mouse enter
- mouse leave
I could create an 'enter'-event case and a 'leave'-event case,
and then assign the enter- or leave- events of the 500 controls
to these 2 cases.
But that would take hours because I have to assign each event to this
case individually for every control.
Is there a way to do this faster :
Can I assign all 'mouse enter' events on the 500 controls to 1 event case
where the case tells you on which control the mouse has entered using a ref?

Answer 1

You can compare the New value with the Old value with a "Not equal" comparison, convert the resuting booleanc luster to an array and then search for TRUE.  This will give you the index of the cluster elements which has changed.
Now you can use the Controls[] property of the cluster reference with this index value to get a reference to the actual boolean which has changed.
Example included (LV 6.1).
Hope this helps
Shane.
Edit: In hy hectic, I failed to notice you actually want Mouse enter and Mouse leave events.
This is much harder.  I advise solving the problem in another way.  LV 6.1 doesn't actually have Mouseover events......

Using LV 6.1 and 8.2.1 on W2k (SP4) and WXP (SP2)
