环境:vs.net + winXP SP3
一般步骤：
定义标识:
#define WM_CALCULATE WM_USER+1
声明消息:
afx_msg LRESULT OnCalculate(WPARAM wParam,LPARAM lParam);
关联：
BEGIN_MESSAGE_MAP(Cxxxclass, Cxxxbaseclass)
//{{AFX_MSG_MAP(Cxxxclass)
ON_MESSAGE(WM_CALCULATE,OnCalculate)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
消息定义:
LRESULT Cxxxclass::OnCalculate(WPARAM wParam,LPARAM lParam)
{
........
}
一般的自定义消息这样做就可以了,今天在搞多线程的一个例子的时发现当你的类派生自一个线程类CWinThread时就行不通了
其中关联的地方写成:
ON_THREAD_MESSAGE(Cxxxclass,Cxxxbasecalss);
MSDN解释：
ON_THREAD_MESSAGE must be used instead of ON_MESSAGE when you have
a CWinThread class. User-defined messages are any messages that are not
standard Windows WM_MESSAGE messages. There should be exactly one
ON_THREAD_MESSAGE macro statement in your message map for every
user-defined message that must be mapped to a message-handler function
我发单改这里还不行说LRESULT不成转成void，我于是把返回类型LRESULT改成void,运行成功，至于能否响应一会之后才知道
