Hi!
I want to find a static pointer for an dynamic adress, the problem is: adress holds text value, and that value is a name, that of course doesnt change during program running, so i cant find out what writes to the adress, but i got the assembly code for what seems to print the name, and check if it's less than 30 chars
so, if you have any idea on how could i find this, it would be really helpfull to me, as i spent countless hours trying to figure out what should i do... (if you want assembly code that i found, just tell me, il post it up)

can't you place a write breakpoint on the name in the debugger and check when a function writes to it? or you refer to something else?

when i place it, it wont bump onto it because it is initialized when program starts, and doesnt execute the code that prints name any time else, so i wouldnt get anything (by my logic it wouldnt bump to breakpoint)

Well, i think i managed to get something, but im not sure, as i cant test it
76e32038 - 66 89 47 08 - mov [edi+08],ax
was scanning for what writest ot name adress, and when i was closing the program down, this showed up now, i guess that this would unload the name, or something, but i dont know how to test what would it actually do...
il try to put breakpoint on it and see what acceses it
