    Anyone know how to log the values of a register while debugging a process in VC++?

    I want to log the EIP register which will basically give me program flow from offsets.

    Yes you could use inline assembler. THis is kind of handy too:

    Code:
    register unsigned long *EIP asm("EIP");
    ...
    printf("%ld", *EIP);

    Since I wasn't familiar with the EIP registers I tried some code...I couldn't get anything to work. Here is a working example though:

    Code:
    //note: use all lowercase in the asm
    register unsigned long *EAX asm("eax");
    ...
    printf("%ld\n", *EAX);
    If someone knows about the EIP thing they can help you but this should give you a step in the right direction. By the way your debugger most likely allows you to dump registers. Try that too.

    Thanks, I cam do a
    mov EAX, EIP
    just before I output. Only thing is I think this will only show me values of EIP in my process. There's something special that VC++ and other debuggers do to attach to another process.
