    Re: changing of exe

    Do you mean change the code inside the exe ? What are you trying to do ? Cracking somebody's work ?

    Re: changing of exe

    OllyDbg is a well-known debugger/disassembler in the reverse engineering community which lets you view/edit the assembly for an executable, among other things, and yes, you can change the code in an exe with it, but as Krishnaa mentioned, cracking is what it is usually used for.

    If the work is yours, why not work in the original code? Editing jumps is one of the base techniques in cracking. Pardon if everyone may have suspicions as to what you are doing, but can you explain more why you need to do this?

    Edit: I read your other post, and what you are wanting to do does make more sense now, although unless you wrote Flash Player, I don't think that counts as your work. Although what you want seems to be a minor no-harm-done change, not a crack of some sort, I'm a little hazy on the exact legality of it. Regardless, this is a visual c++ forum.

    Thumbs up Re: changing of exe

    Hi,

    Instead of changing player exe, why don't you write wrapper around shockwave flash control.

    which will be more powerful...! and easy task. !
