Because the Winsock or DPlay thread was closed I''ll clarify one point here which isnt related to that question: DirectPlay8 and onwards does not use TCPIP at all. (this in relation to the ''why limit yourself to TCPIP with DPlay?) The MSDN documentation contradicts itself a bit as to whether it uses TCPIP or UDP, but unequivocally it uses UDP, even when using guaranteed messaging (as I am). If you check the ports it opens, and search the docs hard and then speak to MS about it you find out it never uses TCPIP. Strange but true. Robert Swan

hello,

what do you mean it never uses TCP/IP? anyway please clarify what does SetSP() does when you include their the protocol that you''ll be using,

thanks,

DirectPlay ONLY uses UDP for its'' IP Service Provider.

so uh., does that mean it doesn''t guarantee the messages being sent when using TCP/IP on DirectPlay?

Of course not. In DirectPlay 7 there was a DPlay Service Provider that would add functionality to other Service Providers that don't provide it natively. In DirectPlay 8, all of that is transparent to you.

If you think about Direct3D and how the HEL emulates functionality on devices that don't support specific features, DirectPlay is pretty similiar in that it provides code to ensure guaranteed delivery over UDP.
