Help on adding a hack

Ok im going to add a hack for Combat arms and i need a little help on doing that also the hack is a wallhack

1: i need to know how to take a screenie
2:i need to know how to put the hack on here without using ********* thgats the only way i know how
3: My friend is testing the chams,so it might be up to an hour before i can post it in the combat arms hack section



P.S. i did not leach this hack. what i did was take a working injecter that didnt have a workign cham and found a working cham that didnt have a working injector and put them together and walla! i got a working wallhack




EDIT: I dont know how to post a virus scan too so when i post the hack in the combat arms hack folder can someone virus scan it plz?
