在ATL中怎么加上消息映射

[xinyu_78]

在ATL中怎么加上消息映射,我是个ATL新手,按以前MFC的都不好用,请高手帮忙,解决后一定放分!

class CWinHidden:
public CWindowImpl<CWinHidden, CWindow, CNullTraits>
{
BEGIN_MSG_MAP(CWinHidden)
MESSAGE_HANDLER(WM_TIMECHANGE, OnTimeChange)
MESSAGE_HANDLER(WM_TIMER, OnTimer)
MESSAGE_HANDLER(WM_SOCK_EVENT,OnSockEvent)
END_MSG_MAP()
public:
CWinHidden(CSockCtrl* pMyCtl) : m_pMyCtl(pMyCtl){};
LRESULT OnTimeChange(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
// TODO : Add Code for message handler. Call DefWindowProc if necessary.
return 0;
}
public:
LRESULT OnTimer(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
LRESULT OnSockEvent(UINT uMsg,WPARAM wParam,LPARAM lParam,BOOL& bHandled);
private:
CSockCtrl* m_pMyCtl;
};
这是我的一小段程序，里面就有消息映射

我也是要用计时器,只要把你的类里的代码加到我的类里就行了吗

这个就是我的类

ATL中，消息映射的格式：
MESSAGE_HANDLER(WM_TIMER, OnTimer)
你上面所写的消息映射格式不对
处理函数声明为:
LRESULT OnTimer(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);
另外，在你的程序中没有窗口，你可以在New ATL Object时选Full Control
ATL会给你生成窗口，并且程序中会有下列语句：
BEGIN_MSG_MAP(CSockCtrl)
CHAIN_MSG_MAP(CComControl<CSockCtrl>)
DEFAULT_REFLECTION_HANDLER()
END_MSG_MAP()
这就是ATL的消息映射了
或者像我写的那个类那样，生成另一个辅助窗口类，使用它的句柄接收消息，在辅助类的消息处理函数中，调用主类的处理函数
