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？
stdafx.h:

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
stdafx.cpp:
#include "stdafx.h" #if defined _M_IX86
#pragma comment(linker, "/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_IA64

#pragma comment(linker, "/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
#endif
主要处理的是产生窗口的样式问题
ControlEx.h:
#pragma once class ComputerExamineUI : public CContainerUI
{
public:
ComputerExamineUI()
{
CDialogBuilder builder;
CContainerUI* pComputerExamine = static_cast<CContainerUI*>(builder.Create(_T("ComputerExamine.xml"), (UINT)));
if( pComputerExamine ) {
this->Add(pComputerExamine);
}
else {
this->RemoveAll();
return;
}
}
}; class CDialogBuilderCallbackEx : public IDialogBuilderCallback
{
public:
CControlUI* CreateControl(LPCTSTR pstrClass)
{
if( _tcscmp(pstrClass, _T("ComputerExamine")) == ) return new ComputerExamineUI;
return NULL;
}
};
这里主要演示了自定义控件的使用方法，这部分可以等到分析控件生成过程的时候再详细说一下

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:
LRESULT CALLBACK CWindowWnd::__WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
CWindowWnd* pThis = NULL;
if( uMsg == WM_NCCREATE ) {
LPCREATESTRUCT lpcs = reinterpret_cast<LPCREATESTRUCT>(lParam);
pThis = static_cast<CWindowWnd*>(lpcs->lpCreateParams);
pThis->m_hWnd = hWnd;
::SetWindowLongPtr(hWnd, GWLP_USERDATA, reinterpret_cast<LPARAM>(pThis));
}
else {
pThis = reinterpret_cast<CWindowWnd*>(::GetWindowLongPtr(hWnd, GWLP_USERDATA));
if( uMsg == WM_NCDESTROY && pThis != NULL ) {
LRESULT lRes = ::CallWindowProc(pThis->m_OldWndProc, hWnd, uMsg, wParam, lParam);
::SetWindowLongPtr(pThis->m_hWnd, GWLP_USERDATA, 0L);
if( pThis->m_bSubclassed ) pThis->Unsubclass();
pThis->m_hWnd = NULL;
pThis->OnFinalMessage(hWnd);//这里用到了onFinanlMessage
return lRes;
}
}
if( pThis != NULL ) {
return pThis->HandleMessage(uMsg, wParam, lParam);
}
else {
return ::DefWindowProc(hWnd, uMsg, wParam, lParam);
}
}
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);
void CPaintManagerUI::Init(HWND hWnd)
{
ASSERT(::IsWindow(hWnd));
// Remember the window context we came from
m_hWndPaint = hWnd;
m_hDcPaint = ::GetDC(hWnd);
// We'll want to filter messages globally too
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*/
}
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
HWND CWindowWnd::Create(HWND hwndParent, LPCTSTR pstrName, DWORD dwStyle, DWORD dwExStyle, const RECT rc, HMENU hMenu)
{
return Create(hwndParent, pstrName, dwStyle, dwExStyle, rc.left, rc.top, rc.right - rc.left, rc.bottom - rc.top, hMenu);
} HWND CWindowWnd::Create(HWND hwndParent, LPCTSTR pstrName, DWORD dwStyle, DWORD dwExStyle, int x, int y, int cx, int cy, HMENU hMenu)
{
if( GetSuperClassName() != NULL && !RegisterSuperclass() ) return NULL;
if( GetSuperClassName() == NULL && !RegisterWindowClass() ) return NULL;
m_hWnd = ::CreateWindowEx(dwExStyle, GetWindowClassName(), pstrName, dwStyle, x, y, cx, cy, hwndParent, hMenu, CPaintManagerUI::GetInstance(), this);
ASSERT(m_hWnd!=NULL);
return m_hWnd;
}
