Control elements are out of control in event structure

[Guo Zhongge]

I have a programm that has 4 cases in Event handler. In third case there is a while loop, after that I can't klick the control elements any more. But I have tried that without this while loop the event handler worked well.Thanks in advance.

It just sounds like your While Loop is not ending. If it is still spinning, nothing on your panel will respond that isn't in a parallel process (separate loop).

Hi!

Posting the vi or an image will help those who want to help you.

What is happening, in my opinion,  is that the Event structure is waiting for the while loop to finish before processing the next event.

As also pointed out by Broken Arrow,

your while loop keeps running, blocking the Event Strucure.

In order to solve the problem you have to split the different tasks of your code in parallel loops.

After control element was klicked, I wanna process the while loop. Until another control element is clicked I can stop this loop and wait for other cases.

How to split?

Look in the LabVIEW New file (File->new...) for the Producer Consumer structure.

Hi!

Try looking here: Application Design Patterns: Master/Slave

I have used that structure. Until now that is only possible to react with first calling. Is there a way to let the occurence react with second, third ... .
