Hello,

Is there a utility available that will monitor and log changes made to a specific memory area under Windows XP ? I'd like to log changes made to a specific memory region.

Please let me know.

Thx.

Easy, set a guard page at the page you'd like to monitor and you'll be told whenever the address is read from or written to.

In Ollydbg, the target only uses the memory for a brief moment. When I try to set a breakpoint on memory access, ollydbg says there is no memory there. The program has not allocated yet. How do you get around this ?

use a hardware breakpoint when the memory *IS* there, and then restart the program being debugged. As soon as the memory exists, the breakpoint will be valid and active.

sometime may remove by packer.such as asprotect .
