not able to handle events

[TRanjith]

Hi.. 

I am using event structure in main vi. for one of the event i am opening new vi which again handles events. New vi is from template(Top level aplication using events).

Here i have a problem. After opening new window, i am not able to handle events on parent window. but i am able to perform non event based actions. Any help would be great!!..

For the parent VI to be able to continue processing events, its event loop must continue running after the other VI is launched - which it won't do if you are calling it as a subVI or using a call by reference node to run it.

Showing some code would also be helpful.

I only guess...

you can not handle events because to handle another event, the previous must first be completed.

As you open a sub vi, you must close this vi, to end the event, and continue with the other events.

Solution do not call your sub vi inside the event structure, or call it dynamically. I prefer the first.

Hi..

Please see attached files for the code. and for the problem.

Here i sould not allow user to popup multiple "controls" but when it opened he should be able to handle parent window events. which is not happening for me.

Thank you,

Hi Ranjith,

as other said before: other events are processed when the actual has finished!

When you need to process "Controls" in parallel you have to program it that way - see attachment for a (very simple) implementation...
