Wait untill button is pressed

[Abuzar]

Hi,

Is there any function available in LabVIEW which pause the execution untill the button is pressed?

I mean at a stage, i need my program to wait untill the button is pressed, so is there any function available to achieve this.

Kindly guide.

Use an Event Structure with only a case for the button you want to press. Wire this in the path of your execution, for example using the error wire. You don't need to do anything in the structure.

I do that as well but make sure the "Lock FP ..." option is NOT selected in that event case. If they hit the button twice the FP will lock-up.

What you need is a state machine. One state waits for button presses.

That would misfire nearly 100% of  the time. assuming there are other controls on the front panel. Also, are you sure that the button state is read after the activity is detected. Most likely you read the stale state from when the loop started.

It works fine.  I've used it many times.
