I have found a program. . . .

The world smallest win32 program ?
Posted on 2003-05-20 10:02:46 by QS_Ong
It size only 1024 byte !!!!

Nay, the smallest exe i have seen is 300+ bytes.

Smallest one i seen is, 74 bytes, all it does is, Open an MS-DOS window and writes hello

There has been many discussions to this topic.

The smallest is 0 bytes.

The smallest is 0 bytes.

Then it would not be an executable because it does nothing.

It would have to be a single opcode with the least amont of clock cycles to be a exe.

Probably a NOP.

If it's able to be executed, it's executable.

Make a 0 byte COM file and run it in MS-DOS. And if MS-DOS won't run it, write an OS that will. And there you'll have it.

it says win32 program doesn't it? not <insert os here> program.

Privalov's COM demo is only 22 bytes:

; fasm example of writing 16-bit COM program

org 100h ; code starts at offset 100h
use16 ; use 16-bit code

display_text = 9

mov ah,display_text
mov dx,hello
int 21h

int 20h

hello db 'Hello world!',24h

That's still not a Win32 program.

It's only a Win32 exec if it is a valid PE file.

What is C--?

What is C--?

C-- is a combination of C and asm, kinda like C++ but reversed, going smaller and lower.

What I mean is win32 program with functional window & button.

Anyone can make this program smaller than 1024 byte ?

Hutch MASM32 example min program is 1500 byte +

But this one only 1024 byte :eek:

I am working on it, coding in hex.

The same using FASM :) I don't think there is possible to make the program smaller then 1024bytes because of PE file format limitations.
