MFC Message Map Problem

For some reason, the compiler is giving me an error when I try to use a custom message. Here's the problem:

Code:

error C2440: 'static_cast' : cannot convert from 'void (__thiscall CStageZeroNetworkAnalysisView::* )(WPARAM,LPARAM)' to 'LRESULT (__thiscall CWnd::* )(WPARAM,LPARAM)'

And how I implemented it:

Code:

//////// View.h
afx_msg void OnNewPacket(WPARAM wParam, LPARAM lParam);
DECLARE_MESSAGE_MAP()


//////// View.cpp
BEGIN_MESSAGE_MAP(CStageZeroNetworkAnalysisView, CView)

	ON_MESSAGE(MSG_NEW_PACKET, OnNewPacket)
END_MESSAGE_MAP()


///////// The function
void CStageZeroNetworkAnalysisView::OnNewPacket(WPARAM wParam, LPARAM lParam)
{
	ZeroPacket* ZP = new ZeroPacket();
	ZP->SetData((pcap_pkthdr*)wParam, (u_char*)lParam);
	ZP->Serialize(ZData);
}

Any help will be much appreciated. Thanks.

Hi,
the function must return value LRESULT:

afx_msg LRESULT OnNewPacket(WPARAM wParam, LPARAM lParam);

and the similar changes in cpp file.
