Unregister from UI events?

[Fedor]

Hello,

I wonder if it is possible to "unregister" the event structure from querying the UI events once the VI is no longer interested in interacting with user? For example, a VI might have to run clean-up code for extended time outside the "while/event" structure combo after the user have pressed "Stop" button. If the user continues to interact with UI objects, it would cause the UI lock-up if the "Lock front panel" was checked for the particular event cases and may cause "user panic" or just feel "unclean".

Good question. Some answers:

• Simple answer: NO, you cannot programmatically unregister a statically registered UI control with the event structure. Once it's statically registered (with the register events dialog) it will always respond to UI events until the VI is done.
  
• You can however dynamically register your UI controls. Then you have the option to either unregister the controls by executing the Register for events node with a null reference (on a per control basis), OR execute the Unregister for events node.
  
• Another option is to disable the front panel controls with the disable property after you click the stop button so you don't have to worry about events firing.
