Hi @ all,

I have a problem with finding a pointer, I actually dont know how to calculate the offset.

esi+ecx*4-04 this is the Offset

-> esi = 0?
-> ecx = 0?
-> *4
-> -04

(esi+ecx-04) * (4)? or what?

can somebody please explain?

thanks

it'll be more easy to help if you put a pic.

[syntex]

cant you just tell me how to calculate it?

cause it takes ages to search that value again

I can't say like that,but i'll post here a pic.

This one is a easy one!

esi+ecx*4-04

my looks like this in red

[Dark Byte]

esi+ecx*4-04

esi=basepointer
ecx=element in array
-4 =adjustment in calculation. (most likely an array starting from index 1 ?)

so, the offset is ecx*4-4
remember it's all in hex, so set your calculator to hex when calculating
ecx=0 -> offset=0*4-4=-4
ecx=1 -> offset=1*4-4=0
ecx=2 -> offset=2*4-4=4
ecx=3 -> offset=3*4-4=8
ecx=4 -> offset=4*4-4=c
ecx=5 -> offset=5*4-4=10

thanks Dark Byte,

Why it is like this?
ecx=5 -> offset=5*

why do you count ecx up to 5? could you explain this part?
and how it comes that you know it counts up to 5?

Thank you so much

@@@@EDIT@@@@

I see its just an example to show what happens when ecx 5*-04 happens

[nog_lorp]

ECX is the "counter register", it is usually used to count place in loops (like "int i" in most languages).

DarkByte was just going up to 5 as an example, 5 doesn't have any special significance.

Also, it is ecx*4 - 4, ecx times 4, minus 4. The multiple (4) signifies the number of bytes in each element of the array.

What you want to do is Find What Accesses This Address, and double click the line with that code ([esi+ecx*4-04]) and see what ECX and ESI are.

[syntex]

what about this?

so esi+ecx*4-04 = c ... im right?
1A487E20 + 00000001 * 4 - 4 = 1A487E20
00000001 * 4 - 4 = 0

this will be a hard one >.<
