OnWndMsg是在 Cwnd 中定義的虛函數(shù)；CWnd::OnWndMsg
virtual BOOL OnWndMsg( UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult );
Remarks
This member function is called by WindowProc, or is called during message reflection.
因?yàn)椴还苁鞘裁搭愋偷拇翱诨惖母磶缀醵际荂Wnd(在MFC中)；
所以巧妙的利用這個(gè)函數(shù)可以實(shí)現(xiàn)很多不能正常辦法實(shí)現(xiàn)的問題；
簡(jiǎn)單舉例子就是：
在 ListCttl中 Head的鼠標(biāo)右擊消息；
利用OnWndMsg截取Head的WM_RBUTTONUP消息
然后自定義消息發(fā)送給所需要的窗口中去；
利用OnWndMsg無所不能
BOOL CMainFrame::OnWndMsg( UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult )
{
if(m_bActive)
{
static unsigned long i=0;
i++;
char buf[256];
sprintf(buf,"%08ld:%08X %08X %08X %08X",
i,message, wParam, lParam, pResult);
m_lb.InsertString(0,buf);
}
return CFrameWnd::OnWndMsg(message, wParam, lParam, pResult);
}
