[NuMetal]

also i want to know whick function to use to make the camera stop by using stop botton

So you want to capture, process, result and continously go on right. Put all the image processing in a sub vi. Bring the subvi inside the while loop. Stop the loop only when u want to quit and cloase labVIEW. Right?

i want just capture , process, result but don't need to continously go on but if i click the OK button again to make the program capture , process, and result the new one

and the stop button is to quit Labview

Simple. Use a case structure inside the while loop. Use two buttons. Select ok to capture image. If you dont select any button the while loop will loop around the default case so make it empty. Connect the stop button to the while termination. Got it?

so which to put in the Case structure ? the whole program or just the function which use to capture the picture ?
