Can any one tell me how to open .exe files in binary so i can edit the in vb. I know you "can't" really edit it, but i am trying to make a program that randomly mutates an .exe file's binary code. i want just need to know how you open it so my program can do what i designed it to do (randomly alter some of the binary code) and how to save the binary back into the similar .exe format. lol i can almost imagine my mutated exe files, im sure...
