This message tests a point to determine whether the point is within the bounding rectangle of a specified tool and, if the point is within the rectangle, retrieves information about the tool.
Syntax

lParam = (LPARAM) (LPHITTESTINFO) lphti;
Parameters
- wParam
Not used. Set to 0.

If the point is within the rectangle, the ti member of the TTHITTESTINFO structure, which is a TOOLINFO structure, receives information about the tool that occupies the point. You must set the cbSize member of the TOOLINFO structure before you send this message.
Return Value
