Hm, I hadn't expected sendMessage to work based on something I'd found when googling before but that does. Presumably because it uses the child window

Since I'm not sure how atom0s found the number 5 all I can tell you is to test random numbers with your game and see if you can get it to work. While CE does have a "dissect windows" tool accessed from the memory browser for notepad it only shows the main window not the children for notepad so not sure if that'll be any use here...
