I'm using the App Designer to build a small app to use a National Instruments Daq (USB-6343) to do both analog input and output. I have two different "modes" that I use. Mode #1 (button #1) outputs and records for a set period of time. Mode #2 (button #2) outputs continuously until another button press (button #3). In the code for button #3, I reset the daq using "daqreset" and re-establish each of the channels that I want to use for Mode #1 (I use Mode #1 much more frequently, so it is much faster if I don't have to set up the daq every time inside button #1 code). If I wait 5-10 seconds after pressing button #3, then I have no problems pressing button #1. However, if I try to click button #1 too soon after clicking button #3, then the App crashes with various errors related to the daq, I believe because the previous code from the end of button #3, which resets the daq, has not finished running, so the daq settings are not correct for the commands I use in button #1.

I would like to be able to ignore all button clicks / user inputs from the UI until all active code has finished running the daq reset section (button #3), to prevent users from accidentally crashing the App. I have found examples of pausing the matlab code until there is a user input, but I would like to do the opposite. Are there any commands / strategies to accomplish this?
