//
// An "In-Place control is a standard Windows control that is used to 
// help editing values.
// These controls send an end-editing message to the parent whenever they 
// think that an action should terminate the editing process.
//
// Currently signaled events are:
//   - VK_RETURN, VK_ESCAPE key press, for edit controls (IPEK_KEY)
//   - CLICK for button (IPEK_ACTION)
//   - WM_KILLFOCUS, for any control (IPEK_FOCUS)
//

// This registered message is used to communicate to the user
// that an event occured so that the editing process should stop.
// User must call RegisterWindowMessage to register this message 
// with the provided string.
//
// wParam: Unused
// lParam: Pointer to a IPEENDEDITINFO structure
// Return Value: TRUE to end editing process, FALSE to continue anyway
//
