This is my bot (image):
Based on memory editing, SendMessage and SendMessageA.
it can be work fully minimized/hidden, there's a "Status-Bar" you can toggle on/off.
this Status-Bar help you to "watch" your char's stats while the game is minimized/hidden.
you can also completely "hide" the client (the game) and the bot will keep on working.
the bot has been made for the CBT about month ago, this version (0.3) is still working*
* tested 1 hour ago
I'm thinking about going on a public-release due to your requests.
I'll update you as soon as I'll finish some stuff over here =)
Have a good and happy new year!
