How do you get more than one button on a form to be activated at a given time. I have a program performing a simulation which is in a loop and this simulation is started after clicking one of the buttons(start), the other button is a stop button. I want to know how I can stop the simulation despite of it being in a loop therefore how to activate the stop button. I am using delphi 2.0.

Place this line of code in your loop:
Application.ProcessMessages;
