求大侠帮忙：为什么最简单的LButton消息都不能响应?

你要捕获哪个窗口的鼠标消息就在哪个窗口类中添加鼠标消息！！！

受打击是正常的哈。

BOOL CMyApp::InitInstance()
{
CFrameWnd* p=new CFrameWnd;
p->Create(0,"yang");
p->ShowWindow(SW_SHOWDEFAULT);
p->UpdateWindow();
//AfxGetApp()->m_pMainWnd=p;
this->m_pMainWnd=p;
return TRUE;
}
--------------------
不明白你为什么要这样写，这样的　P还有什么用呢？这个函数退出后，指针就失效了，而且你还造成了内存泄漏

而且怎么能够this->m_pMainWnd=p　　？？这样写呢？？真是强
