const CString SHARE_NAME="MyShareMem";
HANDLE hMap=CreateFileMapping(INVALID_HANDLE_VALUE,
NULL,PAGE_READWRITE,0,200,SHARE_NAME);
if(hMap!=NULL)
{
if(GetLastError()==ERROR_ALREADY_EXISTS)
CloseHandle(hMap);
else
{
PVOID pView=MapViewOfFile(hMap,FILE_MAP_READ|FILE_MAP_WRITE,
0,0,0);
if(pView!=NULL)
{
....
if(UnmapViewOfFile(pView))
SendMessage(hWnd,WM_AUTOPLAY,0,0);
}
}
}HANDLE hMap=OpenFileMapping(FILE_MAP_READ|FILE_MAP_WRITE,FALSE,SHARE_NAME);
if(hMap!=NULL)
{
PVOID pView=MapViewOfFile(hMap,FILE_MAP_READ|FILE_MAP_WRITE,
0,0,0);
if(pView!=NULL)
{
char szText[100];
memcpy(szText,pView,100);
...
UnmapViewOfFile(pView);
}
CloseHandle(hMap);
