他是在PreCreateWindow中调用的注册，

// TODO: Modify the Window class or styles here by modifying // the CREATESTRUCT cs return TRUE; }

有几点要说明
（1）m_pMainWnd，头文件里并没有这个变量呀？ 噢，这个在基类里定义的public 类型的变量，所以，他是通过继承得到的。
(2) 你注意过吗，当我们一点运行，会默认出来一个视图窗口，这是谁调用的呢？哦，就是下面这几行，它调用了opendocument() 函数。
CCommandLineInfo cmdInfo; ParseCommandLine(cmdInfo); if (!ProcessShellCommand(cmdInfo)) return FALSE； （3）这个函数有个关键的地方 CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate(IDR_myTYPE, RUNTIME_CLASS(CmyDoc),
RUNTIME_CLASS(CChildFrame), // 自定义 MDI 子框架 RUNTIME_CLASS(CmyView)); if (!pDocTemplate) return FALSE;
AddDocTemplate(pDocTemplate); 通过它，把视图，窗口和文档结合起来。
4:主窗口CMainFrame的创建
(1)通过CMainFrame* pMainFrame = new CMainFrame;
我们得到的是不断调用的基类 CMainFrame::CMainFrame() {
// TODO: 在此添加成员初始化代码 }
CMDIFrameWnd::CMDIFrameWnd() {
m_hWndMDIClient = NULL; }
CFrameWnd::CFrameWnd() {
ASSERT(m_hWnd == NULL);
m_nWindow = -1; m_bAutoMenuEnable = TRUE; m_lpfnCloseProc = NULL; m_hMenuDefault = NULL; m_hAccelTable = NULL; m_nIDHelp = 0; m_nIDTracking = 0; m_nIDLastMessage = 0; m_pViewActive = NULL;
m_cModalStack = 0; m_phWndDisable = NULL; m_pNotifyHook = NULL; m_hMenuAlt = NULL;
m_nIdleFlags = 0; m_rectBorder.SetRectEmpty();
m_bHelpMode = HELP_INACTIVE; m_dwPromptContext = 0;
m_pNextFrameWnd = NULL;
m_bInRecalcLayout = FALSE; m_pFloatingFrameClass = NULL; m_nShowDelay = -1; AddFrameWnd();
// unknown window ID // auto enable on by default // initialize modality support// no idle work at start // not in Shift+F1 help mode // not in list yet // no delay pending
