Hi, is it possible to make ollydbg for example break on certain adress and logging a string pointed by EAX to text file?

Would this need a plugin? Is there such a plugin already?

Thx in advance.

RTFM
hint:: conditional breakpoints (SHIFT+F4), expression: [EAX], decode as: pointer to ASCII/UNICODE string

Eh, I'm a bit slow today.

-Where is the logfile? How do I set change/read it?
-Do I need those square brackets around EAX?

i see that you didnt read the help throughly ...

logfile-there is a window called ... "Log window"
[EAX] = address pointed by EAX content
EAX = value of EAX register

Oh, dumb me! I browsed through the site not knowing there was a help file included.
Got it working now.
