I think you will be OK here.  BSD Sockets are the "standard" TCP/IP or UDP/IP socket.  Winsock is a Windows implementation of BSD sockets.  There is no reason a correctly implemented socket application would not be able to communicate across the network and across different systems (barring network failures, firewalls, etc.)    Peace! -=- James Please rate this message - let me know if I helped or not! * * * If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

See Windows Sockets: Blocking[^] CSocket is a high-level wrapper for a socket (SOCKET). To you, it's always blocking. Whether the underlying SOCKET is in blocking mode or not is handled by the CSocket implementation. For a non-blocking socket you can use the CAsyncSocket class or use Winsock APIs directly.

If you are using VC7.0 or later you should use the ATL7.0 conversion macros instead of the ATL3.0 ones. The ATL7.0 macros do not require USES_CONVERSION.

This does make sense to me, as TCP requires an established connection and for broadcasing and multicasting you don't even know to how many recepicients you are talking. Interesting...   I think that makes sense for things like using PING to try to ping a broadcast address, but not for multicast that is supported by the network hardware.  Since one or more routers could handle connetions to multiple clients, and since the connections are one-way, connection or connection-less would not matter - clients would subscribe to the 'cast by subscribing to the multicast server.  But then again, I have not been close to multicast for some time now, so my memory of it may be faulty.    Peace! -=- James Please rate this message - let me know if I helped or not! * * * If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

Yes it is possible as far as ur server contail real IP. Doesn't metter where is the client. regards, Divyang Mithaiwala System Engineer & Software Developer

Hi, Generally I can't remember any perfect function - all techniques are based on check existance an well-known address. You can try to use BOOL InternetCheckConnection( LPCTSTR lpszUrl, DWORD dwFlags, DWORD dwReserved ); ----------- Mila

Port forwording is done by firewall automatically(u have to write rules).So what is ur purpose. never say die

vcforums wrote: sSql = "SELECT Name, Address " "FROM demo " "ORDER BY field_1"; I suspect that this is your problem. I see where you selected into the demo table the Name and Address but there is no mention of a "field_1". If the field that is in your SQL select statement does not exist, then you will get that "too few parameters" error. Make sure that all of the fields exist in the database that you are trying to read. Why is common sense not common? Never argue with an idiot. They will drag you down to their level where they are an expert.

:wtf: This is Visual C++ / MFC forum, how do you expect to get an answer here. C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg
