>Is there a way to show the small (16x16) version of an icon on a button? Pulling the icon out and dumping it to a temporary bitmap would be acceptable, but it would have to be handled at runtime. Also, the .ico will be compiled into the app if that makes a difference.

Do you want to convert existing icon to 16x16 version or it's this way already? In the second case, can you just reference it in the Picture property of the commandbutton?
