Thank you. I got that hint from several sides. I would be happy if I could control Excel at all from within GTA. I don't need to collect data from the game. I fancy an open workbook and worksheet in the background. All I want as a start is to write "1" to a column's last cell. I once was half an expert in Word-VBA and Excel-VBA and am fighting HKA at present. It works in GTA sometimes, meaning I can sent keystrokes to the game in certain situations e.g. if the text-dialogue is open, I can't open nor can I close the dialogue, however.
