ChatAsyDlg.obj : error LNK2001: unresolved external symbol "protected: long __thiscall CChatAsyDlg::OnSock(unsigned int,long)" (?OnSock@CChatAsyDlg@@IAEJIJ@Z)
fatal error LNK1120: 1 unresolved externals
有2个错误，compiler没问题，build就出错了
前面自定义了消息 #define UMSOCK WM_USER+1
2处代码是： afx_msg LRESULT OnSock(WPARAM wParam,LPARAM lParam);
ON_MESSAGE(UM_SOCK,OnSock)

求解答!
