hello ,
anybody can help me urgently plz.
i have already complete a code using Turbo C.i'm now doing
the documentation for my project. i'd like to print screens of the output from turbo C and paste it in Paint but the bottom PrintScreen SysRq in the keyboard doesn't do the job i want. so what shall i do?
anybody can help me plz.
THANX A LOT
