    I'm used to convert both memory reigsters to hex and binary but when it comes to decimal things become a little more dificult. Can someone land a hand? Thanks

str$()?

[xandaz]

   sorry for this but i'm not used to use macros that much. would it be something like this?

Code Select Expand


invoke SetWindowText,hStatic,WM_SETTEXT,0, str$(eax)
   is this the way you do it? Thanks

[xandaz]

   it gives error can't find  crt__itow. what the hell i'm i doing wrong?

Instead of numerous include statements, use only one:

Code Select Expand

include \masm32\include\masm32rt.inc

.data
HelloW$ db "Hello World", 0

.code
start:
  print str$(eax), " is the current value of eax"
  exit

end start

Have a look at masm32rt.inc, it's a very interesting file.

Check SetDlgItemInt() function.

Code Select Expand

BOOL WINAPI SetDlgItemInt(
  _In_  HWND hDlg,
  _In_  int nIDDlgItem,
  _In_  UINT uValue,
  _In_  BOOL bSigned
);

wsprintf example :

Code Select Expand

.386
.model flat,stdcall
option casemap:none

include     \masm32\include\windows.inc
include     \masm32\include\kernel32.inc
include     \masm32\include\user32.inc
include     \masm32\include\masm32.inc

includelib  \masm32\lib\kernel32.lib
includelib  \masm32\lib\user32.lib
includelib  \masm32\lib\masm32.lib

.data

format1     db '%u',0

.data?

buffer      db 32 dup(?)

.code

start:

    mov     eax,1234

    invoke  wsprintf,ADDR buffer,ADDR format1,eax
    invoke  StdOut,ADDR buffer

    invoke  ExitProcess,0

END start

Two examples I made long ago. The first one is quite simple and write down a unsigned word number, from 65535 to 1, the second one writes signed numbers from -65535 to 65534, a bit more elaborated but easy too. First one with fasm sintax, the second with nasm. Both in DOS format.

xandaz,

Include the following line AFTER all of the include files and get the functionality of all of the macros.

      include \masm32\macros\macros.asm         ; masm32 macro file

[jj2007]

Instead of numerous include statements, use only one:

Code Select Expand

include \masm32\include\masm32rt.in

That includes even macros.asm

(it slows down assembly to have so many includes included; on my Core i5 by about 0.05 seconds)

[xandaz]

   Thanks very much guys. You've been exceedingly helpful. I'll bare that in my heart.

dwtoa from masm32.lib :

dwtoa proc public uses esi edi dwValue:DWORD, lpBuffer:DWORD

Description

dwtoa convert a DWORD value to an ascii string.

Parameters

1. dwValue The DWORD value to convert.
2. lpBuffer The address of the buffer to put the converted DWORD into.

Return Value

There is no return value.

Comments

The buffer for the converted value should be large enough to hold the string including the terminating zero.

dwtoa from masm32.lib :

\masm32\macros\macros.asm (included with masm32rt.inc):

    str$ MACRO DDvalue
      LOCAL rvstring
      .data
        rvstring db 20 dup (0)
        align 4
      .code
      invoke dwtoa,DDvalue,ADDR rvstring
      EXITM <ADDR rvstring>
    ENDM

   Thanks y'all.

   Hi there. I was wondering what macro should i use with str$() to add the word line in the precedence of of the line number. thanks in advance
