if( !FAILED( hr = m_pDP->EnumHosts(&dpAppDesc, // pApplicationDesc m_pHostAddress, // pdpaddrHost m_pDeviceAddress, // pdpaddrDeviceInfo NULL, 0, // pvUserEnumData, size 4, // dwEnumCount 0, // dwRetryInterval 0, // dwTimeOut NULL, // pvUserContext m_pAsyncHandle, // pAsyncHandle DPNENUMHOSTS_SYNC) ) ) // dwFlags
But, as u can see that, there is a DPNENUMHOSTS_SYNC, in the last paramter. So, the operation get sync and if it takes longer time, then the peer enumerating, must have to wait, until it completes.
Now, I wanted to change it, like to cancel the request, if the user want. Then SDK states that use CancelAsyncOperation(...), to cancel the operation.
Now, since I''m new to directplay, I would like to ask a couple of questions about that.
How to make this EnumHost(...) run asynchronously, like I only find 3 possible flags for the the last paramter, but none of them told me how to run it asynchronously.
I tried this, CancelAsyncOpertion(...) with EnumHost(...), along with the DPNENUMHOSTS_SYNC flag in it, it worked, but then it showed another wiered behaviour. Like, if I cancel the the enumeration process, then when I try to close the application, it just froze, no errors, nothing, just froze, when I debug, then I found that the control goes to the IDirectplay8Peer::Close(), but after that, it just stuck there.
Any help in this matter will be highly appricated and thanx in advance.

How to cancel the host enumeration process properly?
Ok, here I go again...
As SDK states, that to enumerate a host, in case of peer2peer case, use the funtion as follows. I did, it work. Fine, no problems.
