Beginner question?

I dont think so. If im wrong here, someone correct me.

This...

Code:

---

mov edx, 100082E0
mov ecx, dword ptr [edx + 0x04]

---

And this...

Code:

---

mov ecx, dword ptr [100082E4]

---

Are the same.

Pretty much.

The first takes longer ;)

True, but essentially they do the same thing (muck like LOOP and DEC / JNZ ;) )

Yes, except that one effects two registers.

And for the LOOP / DEC/JNZ, they are also different in that DEC affects the flags.

Which one affects two registers?

mov edx, 100082E0
mov ecx, dword ptr [edx + 0x04]

Affects both edx and ecx, while the other only affects ecx.

Ok. I see. :)
