How can I use the same event case for different controls dynamically

[kremp@fti-en.com]

OS: Linux 2.6.24-1-686 #1 SMP Sat Apr 19 00:37:55 UTC 2008 i686 GNU/Linux
LabVIEW: Version 8.2

I have a lot of (about 50) controls (numeric, boolean) on my front panel. If a "Value Change" event will be fired by any of them the same event case shall be executed. As I do not want to add all 50 controls to the same event case manually I am looking for a way to do it at run time. Additionally the VI is still under contruction, i.e. controls will be added and removed.

Thanks for any help here.

Regards,
Johannes

Hi Johannes,
collect all your control references (you can use the FP property for it) and create a user event. Connect this user event to your event structure. Now you have one event case for all your controls. See the attached picture.

Thanks Mike. Works as I needed it.

Last thing: I also use "Tab Controls". The controls placed on them are not taken by the your solution. I think I only need to parse the FP array "Controls[]" for "Tab Controls" references and add the correspondent arrays "Controls[]" of the "Tab Controls" to your solution, right?

Hi Johannes,
yes, search for "Tab Controls", use the "to more generic class" function and go through all pages to get the controls on it. The other exception are clusters.

Other exceptions: Individual booleans in radio button controls, numeric displays in graphs, ... I think there may be some others as well, but I do not recall at the moment. Any compound control may have nested parts with their own references.

If you want to change properties other than value, even something like a boolean gets complicated because it has a Caption and the Boolean Strings[4].
