Answer 1

To understand the win32 api stream, you will need to use the visual name of the SPY ++ studio tool.

After that refer to this link

    LPSECURITY_ATTRIBUTES lpAtt=NULL;

    HANDLE INVALID_FILE_HANDLE=(HANDLE)0xFFFFFFFF; //Memory handle
    hMapFile=::CreateFileMapping(INVALID_FILE_HANDLE,
    lpAtt,PAGE_READWRITE, 0,nSize, SharedMemName);
    if (hMapFile == NULL) 
    { 
        ShowSomeMessageBox("Could not create shared memory");
        return NULL;
    }

    LPTSTR pBuf = (LPTSTR) MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS,0,0,nSize);
