Hello,

I was wondering if it's possible to do something like this:

Code:

sMyStruct struct 

   p1 dd 0
   p2 dd 0

ends

struct1 sMyStruct

this EQU struct1 + sMyStruct    ; ERROR HERE!!!

mov [this.p1], 0     ; FAILS!

How can we define "this" to make the above work?

Thanks!

Code:

struct sMyStruct

   p1 dd 0
   p2 dd 0

ends

struct1 sMyStruct

virtual at struct1
  this sMyStruct
end virtual

mov [this.p1], 0     ; WORKS!

But still, I'm not sure this is really useful for you, what are you trying to do exactly?

alorent,

Are you trying to overwrite part of mov [this.p1], 0 instruction with 0? This works:

Code:

struct sMyStruct
   p1 dd 0
   p2 dd 0
ends

struct1 sMyStruct

virtual
  this sMyStruct
end virtual

mov [this.p1], 0

Though mov [$], dword 0 looks simpler.

Thanks guys!

I have tried to make a set of macros to simulate basic OO (Objected Oriented) programming, with the idea of making things more "organized" in assembly and better programming.

I have realized that at the end I will make the code more obscure and dirty as assembly is what it is, assembly Smile

So I was going to get the opposite of my main objective (clarity, better coding).

Well, hopefully someone will make in FASM something that is really OO coding and not something that makes things more obscure Smile

Thanks!
