我想通过360demo的学习，大概就能把握duilib的一般用法，同时引申出一些普遍问题，和普遍解决方法。并在此分享一些链接和更多内容的深入学习。。。。。

原谅我是一个菜鸟，什么都想知道得清清楚楚。。。。god，还有一堆书要看，看完是否就会有豁然开朗的感觉呢？

第1，2,34行：

1 #if !defined(AFX_STDAFX_H__A9DB83DB_A9FD_11D0_BFD1_444553540000__INCLUDED_)

2 #define AFX_STDAFX_H__A9DB83DB_A9FD_11D0_BFD1_444553540000__INCLUDED_

自动生成的吧，大概就是为了避免stdafx.h被重复包含吧。

第4行:#pragma once

这个不多说了，我另一篇随笔有说

第6行:#define WIN32_LEAN_AND_MEAN

参考：更快的生成和更小的头文件

非mfc应用程序可定义这个宏

第7行：#define _CRT_SECURE_NO_DEPRECATE

参考：CRT Security Enhancements (Windows Embedded CE 6.0)

这里说得非常详细，主要是涉及一些旧crt api的安全问题，例如strcpy没有溢出检查等。。。

推荐方法是使用取而代之的strcpy_s等带安全检查的函数，定义上述的宏是为了消除编译警告。。。

第17-29：duilib不同版本的调用方法

参考：这里

参考：Win32 创建控件风格不是Win XP解决方案

主要处理的是产生窗口的样式问题

ControlEx.h:

1 #pragma once

3 class ComputerExamineUI : publicCContainerUI4 {5 public:6 ComputerExamineUI()7 {8 CDialogBuilder builder;9         CContainerUI* pComputerExamine = static_cast<CContainerUI*>(builder.Create(_T("ComputerExamine.xml"), (UINT)0));10         if( pComputerExamine ) {11             this->Add(pComputerExamine);12 }13         else{14             this->RemoveAll();15             return;16 }17 }18 };19

解释1：void OnFinalMessage(HWND /*hWnd*/) { delete this; };

override from CWindowWnd调用来自注册窗体的回调函数:

1 LRESULT CALLBACK CWindowWnd::__WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)2 {3     CWindowWnd* pThis =NULL;4     if( uMsg ==WM_NCCREATE ) {5         LPCREATESTRUCT lpcs = reinterpret_cast<LPCREATESTRUCT>(lParam);6         pThis = static_cast<CWindowWnd*>(lpcs->lpCreateParams);7         pThis->m_hWnd =hWnd;8         ::SetWindowLongPtr(hWnd, GWLP_USERDATA, reinterpret_cast<LPARAM>(pThis));9 }10     else{11         pThis = reinterpret_cast<CWindowWnd*>(::GetWindowLongPtr(hWnd, GWLP_USERDATA));12         if( uMsg == WM_NCDESTROY && pThis !=NULL ) {13             LRESULT lRes = ::CallWindowProc(pThis->m_OldWndProc, hWnd, uMsg, wParam, lParam);14             ::SetWindowLongPtr(pThis->m_hWnd, GWLP_USERDATA, 0L);15             if( pThis->m_bSubclassed ) pThis->Unsubclass();16             pThis->m_hWnd =NULL;17             pThis->OnFinalMessage(hWnd);//这里用到了onFinanlMessage18             returnlRes;19 }20 }21     if( pThis !=NULL ) {22         return pThis->HandleMessage(uMsg, wParam, lParam);23 }24     else{25         return::DefWindowProc(hWnd, uMsg, wParam, lParam);26 }27 }

主要是在接收到WM_NCDESTROY消息的时候，执行最后的一些处理，这里是调用delete this，销毁对象，禁止进一步对对象成员的访问，参考：这里

附：

WM_NCCLIENT 消息在 WM_CREATE 之前，

WM_NCDESTROY 在 WM_DESTROY 之后，

包括标题栏、窗口边框、最大、最小按钮、滚动条等都属于 non-client 区域。

解释2：控件这块，会有后续章节，更深入地去了解

解释3：消息循环，也会有后续章节深入了解

解释4：m_pm.Init(m_hWnd);

1 voidCPaintManagerUI::Init(HWND hWnd)2 {3 ASSERT(::IsWindow(hWnd));4     //Remember the window context we came from
5     m_hWndPaint =hWnd;6     m_hDcPaint =::GetDC(hWnd);7     //We'll want to filter messages globally too
8     m_aPreMessages.Add(this);/*添加当前paintmanager对象指针到类静态成员中，用于一些消息的处理，这部分如果有机会说paintManager应该会说说，各位也可以自己看吧*/9 }

当前窗口句柄保存到paintManager

解释5:ControlUI* pRoot = builder.Create(_T("skin.xml"), (UINT)0, &cb, &m_pm);

如果有时间说builder的xml解析，会深入了解

解释6：pFrame->Create(NULL, _T("360安全卫士"), UI_WNDSTYLE_FRAME, 0L, 0, 0, 800, 572);

内部还是调用windows窗体注册过程

1 HWND CWindowWnd::Create(HWND hwndParent, LPCTSTR pstrName, DWORD dwStyle, DWORD dwExStyle, constRECT rc, HMENU hMenu)2 {3     return Create(hwndParent, pstrName, dwStyle, dwExStyle, rc.left, rc.top, rc.right - rc.left, rc.bottom -rc.top, hMenu);4 }5
6 HWND CWindowWnd::Create(HWND hwndParent, LPCTSTR pstrName, DWORD dwStyle, DWORD dwExStyle, int x, int y, int cx, intcy, HMENU hMenu)7 {8     if( GetSuperClassName() != NULL && !RegisterSuperclass() ) returnNULL;9     if( GetSuperClassName() == NULL && !RegisterWindowClass() ) returnNULL;10     m_hWnd = ::CreateWindowEx(dwExStyle, GetWindowClassName(), pstrName, dwStyle, x, y, cx, cy, hwndParent, hMenu, CPaintManagerUI::GetInstance(), this);11     ASSERT(m_hWnd!=NULL);12     returnm_hWnd;13 }
