Hey Magmai (or anyone) I posted this in the Dx forum, and Magmai suggested I try out this one..(thanks dude). I''m just trying to get a simple dplay8 project going..I''m looking for some help creating a basic UDP client/server app going but I''m not sure how to *properly* setup my dplay8 objects.. Yes I''m in the process of reading the sdk docs, and YES I do understand client/server, peer-peer theory (this will be my first mplayer project..) Any samples other than the sdk docs would be helpfull, or even some suggestions as to what I need to remember (ie. any "gotchas").. thanks for any advice/help, Wazoo

Hi wazoo69, here is a snippet of code I use to initialize Direct Play for a peer-to-peer session.

  HRESULT hrInitializeDirectPlay( HWND hWindow ) {	HRESULT	hReturn;	int		i;		// Initialize COM	hReturn = CoInitialize( NULL );	if( FAILED(hReturn) ) {		MessageBox( hWindow, "Error Initializing COM", "DirectPlay Error", MB_ICONERROR );		return hReturn;	}		// Initialize critical sections for multi-threading	InitializeCriticalSection( &g_csModifyPlayer );		// Create IDirectPlay8Peer Object	if( FAILED( hReturn = CoCreateInstance( CLSID_DirectPlay8Peer, 		NULL, 		CLSCTX_INPROC_SERVER, 		IID_IDirectPlay8Peer, 		(LPVOID*) &g_pDP ) ) )        MessageBox( hWindow, "Can't Create DPlayPeer", "DirectPlay Error", MB_ICONERROR );		// Init IDirectPlay8Peer Message Handler	if( FAILED( hReturn = g_pDP->Initialize( NULL, DirectPlayMessageHandler, 0 ) ) ) {		MessageBox( hWindow, "Failed to Message Handler", "DirectPlay Error", MB_ICONERROR );		return -1;	}		// Create a device address	hReturn = CoCreateInstance( CLSID_DirectPlay8Address, NULL,CLSCTX_INPROC_SERVER, IID_IDirectPlay8Address, (LPVOID*) &g_pDeviceAddress );	if( FAILED(hReturn) ) {		MessageBox( hWindow, "Failed to Create Device", "CoCreateInstance()", MB_ICONERROR );		return -1;	}		// Set our service provider to TCP/IP	if( FAILED( hReturn = g_pDeviceAddress->SetSP( &CLSID_DP8SP_TCPIP ) ) ) {		MessageBox( hWindow, "Failed to SetSP() for Device Address", "Invalid Param", MB_ICONERROR );		return -1;	}		// Create a host address	hReturn = CoCreateInstance( CLSID_DirectPlay8Address, NULL,CLSCTX_INPROC_SERVER, IID_IDirectPlay8Address, (LPVOID*) &g_pHostAddress );	if( FAILED(hReturn) ) {		MessageBox( hWindow, "Failed to Create Host Address()", "Invalid Param", MB_ICONERROR );		return -1;	}	// Set the host address to TCP/IP	if( FAILED( hReturn = g_pHostAddress->SetSP( &CLSID_DP8SP_TCPIP ) ) ) {		MessageBox( hWindow, "Failed to SetSP() for Host Address", "Invalid Param", MB_ICONERROR );		return -1;	}	// Create connection complete event for later use	g_hConnectCompleteEvent = CreateEvent( NULL, FALSE, FALSE, NULL );	vShowText(hLB_Output,"<<--TCP INITED-->>");	// Init miscellaneous variables	for( i = 0 ; i < MAX_PLAYERS ; i++ ) {		PlayerInfo[i].bActive = 0;	}		return S_OK;}

Thanks LostLogic!! That''s what I needed to getting started!

(Of course I''ll modify it for client/server, but I get the general idea..)

thanks, and I''ll definitely look at your book when it comes out!
