Hello everyone,

 

This challenge was written by naquadria in at4re forum:

There is a file main.c contains this code:

#include <windows.h>

int iWinMain() {

    MessageBoxW(NULL,
                "PoC",
                "Hello!",
                MB_ICONINFORMATION);

    return 0;

}

1- Is there a mistake in the code ?

2- Is it possible to build it ?

 

Try to answer without testing it.

One more thing... PM me your answer so others can have fun too, I'll post the answer after 3 days :)

it might compile, if you put 'iWinMain' as the EntryPoint. it will definitely compile if you compile it as a .lib

Time is up :)

 

Well, if it was a cpp file "main.cpp" it won't compile... but here it's a c file, so it will compile with no problems. However, it will show a message with unreadable content as A200K indicated.

Why so ?

The unicode version of MessageBox function will treat the string as if it was in UTF-16 encoding which is not the case.
