Hey just wondering how many out there have successfully been using DirectPlay objects inside an OO framework... I''ve got a framework going, but I''m stuck at a problem: DirectPlay8 isn''t working so well within my classes....I''ve got the DirectPlayMessageHandler function declared as a static one, then inside that it reinterprets this into MY NetworkMessageHandler function.. Now the problem is that functions CALLED from this NetworkMessageHandler function aren''t working properly (ie. they don''t even SEE the IDirectPlay8Peer member object anymore) I''m kinda stuck and hoping someone knows wth I''m talking about and can give me a small hand.. thanks!

Hum...

  
HRESULT CNetworkServerDx8::Initialize()
	{
	HRESULT hr;
	
	if(!m_pDPServer)
		{
		TESTHR(m_pDPServer.CoCreateInstance(CLSID_DirectPlay8Server));
		TESTHR(m_pDPServer->Initialize(this, MsgProc, 0));
		}
//...

		if(FAILED(hr=m_pDPServer->Host(&dpnAppDesc, &m_pDP8AddrLocal.p, 1, NULL, NULL, this, 0)))
//...

HRESULT WINAPI CNetworkServerDx8::MsgProc(PVOID pvUserContext, DWORD dwMessageID, PVOID pMsgBuffer)
	{
	CNetworkServerDx8* This = reinterpret_cast<CNetworkServerDx8*>(pvUserContext);
	_ASSERT(This);
	
	switch(dwMessageID)
		{
		case DPN_MSGID_INDICATE_CONNECT:
			return This->IndicateConnect(dwMessageID, reinterpret_cast<DPNMSG_INDICATE_CONNECT*>(pMsgBuffer));

That''s how I hook it up... any help?

YES!!!

I wasn''t reinterpreting the cast correctly in the switch statement within my DirectPlay message handler...argh!

ie. under DPN_MSGID_CREATE_PLAYER I was just calling my
createPlayer(pMsgBuffer)...so inside the createPlayer function
it had no idea/access about the DirectPlay objects already created in my class...

Big thanks!!!
