回复： How to implement a warning before program is stopped?

[automasjon3ea]

Hi.

I have an issue that's probably easy to solve, but which I can't seem to get right.

When the user pushes a Stop-button in the program there should pop up a warning before it is stopped, to confirm that you really want to stop.

What I want is that when the user pushes the stop button - it doesn't change to FALSE before the pup up is confirmed with "yes I want to stop". How can I do this?

The .VI is added, but doesn't solve the problem as it uses a Event Structure based on a value change of the stop-button - but I want the message to come up before the value is changed.

Hope somebody can help me with this 🙂

I would use the two-button dialog function in Dialog and User Interface. It has a true/false output that you could use to end your program.

If you look at the VI you see that I do use a Two-button dialog button, but I want the (true/false) out of it, to control the start/stop-button when the start/stop-button is pressed. Is twanthere any way to do this?

So I don't want to change the value of the start/stop button when it's pushed down. I want the dialog question to be shown when the start/stop-button is pushed, and if the user wishes to end - THEN the start/stop button changes value.

Hope this clear things up.

your vi is the latest, i can't open it. can you change your vi version to 8.2?

i guess your event is in wrong mode.
