示例1: DlgProc

BOOL bMsgHandled = false;
LRESULT lMsgResult = 0;

pDialog = static_cast<CDialog*>(CWnd::s_WndMap.Find(hWnd));

// Time to initialise?
// NB: We will receive other messages first.
if (iMsg == WM_INITDIALOG)

// This function can be called recursively so we need to use
// the program stack to hold the return values for each
// message whilst it is being precessed.
//
// Push the existing messages' return values onto the stack.
