Answering prompt boxes automatically with VBA

As in:

==============

"Changes have been made to the document. Do you want to save?"

[Yes] [No] [Cancel]

==============

I believe VBA can just input the answer automatically so my program doesn't pause for such mundane questions. How do I accomplish this? I'm sure it must be basic to any VB programmer.

You may find you can set the Alerts to False for that operation.
