Good evening! Is it possible to change the value of some variable to another in an already compiled program without recompilation and save it in the same .exe file?

  • I personally do not understand what it means to save in the same .exe file .. <br> Well, yes, the essence of the comment is not in this, the question is different - WHY DO YOU IT? - Zowie
  • You just need to complicate the cipher and I want the value of the variable to change to false after 3 attempts, for example, and the program does not start. - LapinioZX
  • one
    Lazy to write a "ballad", I will write shortly - dig in the wrong direction ... - Zowie
  • Of course, this approach is not entirely successful, but if we add to it the system configuration? I want to do this as an extra protection for not always persistent algorithms. - LapinioZX
  • "save"? What you have described is easily bypassed by creating a copy of a still unlocked version of the program. - Vladimir Gordeev

If we are talking about a constant that is firmly stitched into a binary, then it can be changed by patching the binary to the desired value, determining the place in the exe-file where it is located.

  • Well, it is not constant, but mb is changeable with time. - LapinioZX

Yes. For example, the numeric variable is a.

We change it for example through edit:

a:= StrToInt (edit1.text);

And then save this value using the ini file and unload it when you start the program. I hope how to do ini do not need to write. The Internet is full of tutorials.

The goals of such shnyagi can be different - for example, through such variable cartridges I save in my game.

  • and where is "in the same .exe file"? :) - Zowie
