Hi,
can any one tell how to read Windows NT Quota stream through Window NT Quota API. i have used these interfaces

IDiskQuotaControl
IDiskQuotaEvents
IDiskQuotaUser
IDiskQuotaUserBatch
IEnumDiskQuotaUsers

to get any specific information related to quota of user on NTFS. But i want to read Quota Data stream. (Like, to read standard data stream, alternate data stream etc on NTFS, we use BackupRead). Is there any Api through which we can read Quota data stream.

Thanks for ur reply.

Yah I had read this article. This only gives information of how to get any specific information for a quota assigned to a user on a NTFS volume.

I have found that in Windows NT, all the information about the Quota of NTFS volume is presented in $Quota system file.

While making backup of a file which exist on NTFS volume, i m able to read all the other streams like security stream, object id, standard etc through BackupRead api function which gives all the data related to a particular strema. That's what i want to do with quota stream also.

Plz guide me in this case.

Closing a port given a port number

Hello.

I need help. I wanted to close a port using a port number. Is this possible?

If yes, could anyone inform me how?

Thanks.

Alex

Re: Closing a port given a port number

NiceNaidu25-May-06 2:18

Inorder to close the Port, u need to close the handle of the Port,that u get from CreateFile.

hPort = CreateFile(..........);

for closing this,

if(hPort != NULL)<br />
  CloseHandle(hPort);

You cannot close the port by this method, if port is open by another application!

the error is at:

{_Nodeptr _S = _P._Mynode();
--> _Acc::_Prev(_S) = _Buynode(_S, _Acc::_Prev(_S));

_Acc::_Next(_Acc::_Prev(_S)) = _S;
allocator.construct(&_Acc::_Value(_S), _X);
++_Size;
return (iterator(_S)); }

I declare it in a class

class PerIOData : public OVERLAPPED
{
public:

int m_Operation;
SOCKET m_Socket;
WSABUF *m_pBuf;
int m_BufNum;
int m_NextStart; std::list<wsabuf*> m_ListBuf;
};
use like this, in a thread:
PerIOData *p=new PerIOData
...
p->m_pBuf=new WSABUF;
p->m_pBuf->len=128;
p->m_pBuf->buf=new char[128];

when data is received through IOCP:
p->m_ListBuf.push_back(p->m_pBuf);
