Some controls will get this for you automatically. For example when ScrollBars join at the lower-right corner of the Form, or you have a StatusBar, etc.
However when you don't have or want these but your Form is sizable you may want the sizing grip because in the post-Win7 world you no longer get fat borders. Actually they still are fat, but the fat part is transparent making them look thin to the user.
It turns out that you can turn a VB6 intrinsic ScrollBar control into a sizing grip fairly easily. It works both with and without Common Controls 6.0 UxTheming, and it is a real sizing grip visible as such to Windows Accessibility unlike funky hacks like sticking a Label or something in the corner and capturing the mouse when hovered over and clicked.

However you do still have to position it in your Resize event handler, because it doesn't get docked/aligned automagically:
Of course the attached demo moves and sizes a few more controls in its Resize handler. ;)
