Another option would be to install a KeyboardProc and keep
processing the message queue as you draw.
The KeyboardProc hook procedure is an application-defined or
library-defined callback function used with the SetWindowsHookEx
function. The system calls this function whenever an application
calls the GetMessage or PeekMessage function and there is a
keyboard message (WM_KEYUP or WM_KEYDOWN) to be processed.

Hi,
Well, windows32 applications operate in their own protected address
space. So, if your two application processes/windows are existing in
two different address spaces, you will need to use any form of IPC
mechanism to establish communication between them, named pipes
are efficient, easy to use and provide secure access methods, you can
use event objects with named pipes to signal completion and notify
a waiting thread of the occurrence of an event.

How can I capture mouseevents using win32 api over an ownerdrawn
combobox?
need to know which selection the mouse pointer is over at any time?
i know there is the CBN_SELCHANGE message but this only says when a
selection changes not when a mouse is over a selection, hope my
question makes sense - thanks.
