Inform Users of a Long Process

While your code is conquering a long looping process, users might think their system has crashed, unless you provide some visual clue that a process is running.

When a user clicks a button to run a process, and that process takes a while to complete, the user won’t know if the process is still running or if the system has crashed. Just imagine it: you click a button on a form and … nothing. A minute or two later, still nothing. Maybe even 5 or 10 minutes later, the system is still unresponsive.

This is nerve-wracking for the user sitting in front of his computer. He has to weigh whether he should try the break key or let the system continue to look like it is hung up. On the other hand, if he stops a process that was running smoothly after all, he will just have to start it all over again. Ugh!
