    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.

    RE: MFC Message Map Problem

    Hi,
    the function must return value LRESULT:

    afx_msg LRESULT OnNewPacket(WPARAM wParam, LPARAM lParam);

    and the similar changes in cpp file.
