Oops. Just down to the final hurdle on my program to control two devices.

I need the abort button to work which as far as I can tell will only work if I use threading?

My program is fairly simple. Text boxes collect relevant data, Start_Click event runs a few checks then calls my CalculateResult method. Am I going to have to re-write the thing or can I just change the wrapping to cause CalcultateResult to run as a thread that can be interrupted by the Abort button? I haven't used threads before.

Many thanks for all your help so far and in advance for any response.
