第1步： 新建控制台工程，主进程代码如下

#include "stdafx.h"#include "windows.h"int _tmain(int argc, _TCHAR* argv[]){    wchar_t MemShareName[] = L"MemShareForTest";    LPVOID pMemShare;    int data = 10;    //HANDLE hMap = ::OpenFileMapping(FILE_MAP_ALL_ACCESS,0,MemShareName);    HANDLE hMap = ::CreateFileMapping(INVALID_HANDLE_VALUE,NULL,PAGE_READWRITE,0,128,MemShareName);  // hu 空间大小为Bytes    pMemShare = ::MapViewOfFile(hMap,FILE_MAP_ALL_ACCESS,0,0,0);    memcpy((int*)pMemShare,&data,sizeof(data));    printf("%x:%d\n",(int*)pMemShare,*(int*)pMemShare);    data++;    memcpy((int*)pMemShare+1,&data,sizeof(data));    printf("%x:%d\n",(int*)pMemShare,*(int*)pMemShare);    printf("%x:%d\n",(int*)pMemShare+1,*((int*)pMemShare+1));    getchar();    ::UnmapViewOfFile(pMemShare);    ::CloseHandle(hMap);    return 0;}

第2步： 新建控制台工程，从进程代码如下

#include "stdafx.h"#include "windows.h"int _tmain(int argc, _TCHAR* argv[]){    wchar_t MemShareName[] = L"MemShareForTest";    LPVOID pMemShare;    HANDLE hMap = ::OpenFileMapping(FILE_MAP_ALL_ACCESS,0,MemShareName);    pMemShare = ::MapViewOfFile(hMap,FILE_MAP_ALL_ACCESS,0,0,0);    printf("%x:%d\n",(int*)pMemShare,*(int*)pMemShare);    printf("%x:%d\n",(int*)pMemShare+1,*((int*)pMemShare+1));    getchar();    return 0;}

第3步： 依次运行主从进程，结果如下
