[MFC]error C2065: 'm_hWnd' : undeclared identifier 해결 ㅠ_ㅠ

error C2065: 'm_hWnd' : undeclared identifier

위와같은 에러가 나오면 m_hWnd멤버를 사용하는 클래스에  "CWnd m_hWnd;" <- 이것을 추가해주면 된다.

사용예제 

class CGrayImageApp : public CWinAppEx

//class CGrayImageApp : public CWnd

{

public:

CGrayImageApp();

CWnd m_hWnd;

위와같이 추가해주면 된다.

hi i getting following error on the 4th line

                             RECEIVERINFO ReceiverInfo;

ReceiverInfo.dwSize = sizeof( ReceiverInfo );
ReceiverInfo.dwFlags = 0;
ReceiverInfo.hWnd = m_hWnd;
ReceiverInfo.uMessage = WM_HCTNOTIFY;

how to fix this?

답변

Put this code into a member function of some class that does have m_hWnd  as its data member.
