SendKeys() in VB powered basically all of the AOL chat bots in the 90’s.

It’s how I accidentally learned the Win32 API

Me too! With Sendkeys and some Win32 API calls, I wrote an AOL add-on (available through Keyword: addons) called AoLOL!. It was my first software business.

Q: How do you identify the AOL window? A: Look for an app with titlebar = "America[space][space]Online"
