Accessing user interface

[vivek88]

Hi,

I cant seem to be able to access my user interface while the programme is running. For example, stopping the programme using the end button. Attached is the programme file.

THanks

Hello,

I don't have the fieldpoint vi's installed so I've deleted all instances in other to run and see the problem.

It seems that you've a problem of processing. Because if you run your program and check the CPU performance indicator (ctrl+alt+del), if can see that it's 100%.

Solution:
put a delay on the first case false (you should always do this in a while).

Hi vivek,

you configured your events to "lock front panel until event completes" - this will prevent you from using the UI while the event is executed.

You should rethink the design of your program:
- it's no good idea to have code in the event structure that needs a long time to execute - other events have to wait...
- there's a STOP in the 2nd event - do you want to break your vi instead of a graceful shutdown?
- the stop buttons are located off the screen, should the user always search on a scrollable interface for some buttons to press?
- and as told before: always put some delays in loops to prevent cpu-hogging!
