Hi!
I have an instruction in my debugger:

Code:
00E51807 - 89 50 08  - mov [eax+08],edx


My task is to get EAX value before the instruction or get EDX value after the instruction.
Is it possible?
I know instruction address and it is static. (00E51807)

rightclick in the disasembler and choose "Find out what addresses this code accesses"
Then you can rightclick the address(es) that show up and choose the option to view the register states.

EDX will be the same before and after the instruction, same for EAX

Hm... i mean outside CE.
Because in several times, the content of EAX and EDX is different.

All i know is the address of instruction - it is static (00E51807).

So I have to get EAX content before the instruction at address 00E51807 in any time not only when I debug in CE.

Like EAX viewer which would display a value which was stored in EAX just before instruction at 00E51807 was executed.
