Помогите советом плиз.
Есть задачка: MS Excel 97, кропотливо выстроен вид анкеты, предназначенной для последующего сканирования, распознавания, необходимо обработать события нажатия клавиш так, чтобы в текущую ячейку попал 1 й символ и курсор перешел в следующую ячейку, дошел до крайности, не смог решить проще, никак не пойму как обработать event нажатия клавиши е сли нет объекта управления, нашел код управления через API:

'* MODULE NAME: CHECK KEYBOARD BUFFER *

'* AUTHOR & DATE: STEPHEN BULLEN, Stephen@oaltd.co.uk *

'* DESCRIPTION: This module contains an example of using Windows API *
'* calls to check the state of the message buffer. The *
'* example includes a check for "Key down" events, which *
'* are used to stop a loop. The module contains functions*
'* for both 16-bit and 32-bit versions of Windows. *
