thanks all for your responses.

Nice beginning to a follow up message....


But I wanted to ask a couple follow up questions. These are strictly
speaking not VB questions so apologies for that:

A. is it so that (regardless of programming language) the Windows
environment is what provides a way to eliminate loops to wait for user
input?

In a word, yes. For more info see:

Windows UI:

Hooks:

B. in what kind of situations would a loop be required for waiting for
user input?

If at all possible, looping should be avoided in favor of responding to
messages and/or events. One possible situation that may require looping
is when timing is critical, so that your code can continuiously poll an input
or update a display. But, as you may know, Windows itself is not very
well suited for time critical applications.
