Abort task that has not yet completed writing

[jaberbob]

I am generating some analog signals through DAQmx -- these waveforms can be >10 seconds long by necessity (the sample rate is very low). I would like to be able to stop the output of the waveform when I press a button. What happens now, when I use the Clear Task vi, Labview waits some time and throws an error (Error -200292, Some or all of the samples to write could not be written to the buffer yet. More space will free up as samples currently in the buffer are generated.). The task is subsequently cleared, which is what I want, but I don't want the wait time. Is there some way to interrupt the writing of the task? I know it is theoretically possible, becuase I can stop the vi and the output stops, but that is not really a feasible solution.

Thanks!

Like the DAQmx Stop Task VI?

I tried that, it did the same thing. I also tried the abort task vi ( from https://decibel.ni.com/content/docs/DOC-15815) with no luck.

Can you show us what your vi looks like?

Thanks guys, but I figured it out - there was a timeout input when I started the tasks that I had forgotten to wire, and it was set to 10s. Making it smaller solved my problem.
