I should write a Windows32 form, in which I can input Unicode. When I create multiple instances of application.all the form must display some content, and When I change the content, the content in all instances must change according to the changed Unicode.
Now I can get the content of input, but how can I put the value into the variable in commen memory area?

#include "stdafx.h"
#include "windows.h"
#include <memory.h>
#include <TCHAR.h>
//#pragma once

#pragma data_seq("Shared")
volatile wchar_t* content;
#pragma data_seq()
#pragma comment(linker, "/Section:Shared,RWS")
