Description

Processes messages received by the drag object.

WndProc is the first method to receive Windows messages that are sent to the drag object. WndProc handles messages about mouse and keyboard events.

When overriding WndProc to provide specialized responses to messages, be sure to call the inherited WndProc at the end, in order to dispatch any unhandled messages.
