Notify User if Control Data has been changed and allow to save instead of exiting and losing all changes!

[ljmoseley]

When you update a value in a control (specially something as large as a table with hundreds of values changed) on  a VI, LabView doesn’t know or tell or warn you when you exit the VI that there are changes to the values (IT SHOULD AT LEAST WARN YOU)!

If you change the slightest wire/diagram/etc., it warns you to save and has the "*" on the end of the UI/VI title!

WHY NOT do that on the controls? Rather than having to always remember to Right Click, “Save Current Values as Default”…

We LOST HOURS of work/typing (after saving many times, thinking it saved the values – specially in a table)!

It would be nice for Global Variable VI's though. You create a Global Variable VI, add an array of strings. Enter 30 values. Hit save. Close it down (no warnings). Open it up the next day - empty array!

That's because you need to save the values as the default.

Instead of using a Global for this, try using a VI with a constant in it.  Wire up the output from the cosntant and give the VI a nice icon.  Then, any changes you make to the data will be retained when saving the VI.  A Global is designed to be written to and read from, therefore it should NOT save any data changes.

For globals, the idea you're looking for is this one - http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Adding-CONSTs-to-LabVIEW/idi-p/942213
