MoveWindow() SetWindowPos()的区别与联系
转自http://www.cnblogs.com/songliquan/p/3359002.html

先看MoveWindow()函数�Q�用于改变窗口的位置和尺寸，对于��层�H�口�Q�按照屏�q�对齐与左上角，对于子窗口，则对齐与父窗口的左上角�?br />
BOOL MoveWindow( HWND hWnd,int x, int y, int nWidth, int nHeight,BOOL bRepaint = TRUE);
参数hWnd表示�H�口句柄�Q?br />参数x,y表示�H�口的左上角��L(f��ng)��Q?br />参数nwidth�Q�nHeight 表示�H�口高度和宽度；
最后一个bRepaint表示是否立即重绘。�ؓ(f��)true时系�l�会(x��)立即发送WM_PAINT到窗口程序（�?x��)调用UpdateWindow()函数�Q�，为false时不�?x��)发生�Q何类型的重绘操作�?br />
MoveWindow�?x��)给�H�口发送WM_WINDOWPOSCHANGING�Q�W(xu��)M_WINDOWPOSCHANGED�Q�W(xu��)M_MOVE�Q�W(xu��)M_SIZE和W(xu��)M_NCCALCSIZE消息�?br />
接下来看SetWindowPos(),�q�个函数同样用来实现�H�口�U�d��操作�Q�只不过功能更多一炏V�?br />
BOOL SetWindowPos(HWND hWnd,const CWnd* pWndInsertAfter, int x, int y,int cx, int cy, UINT nFlags);
�W�一个参数是�H�口句柄�Q?br />�W�二个参数是�H�口的Z order�Q�就是有多个�H�口�Ӟ��本窗口显�C�的��序�Q�最上面或者最下面�Q�可选参数有:HWND_BOTTOM,HWND_NOTOPMOST,HWND_TOP,HWND_TOPMOST.
HWND_BOTTOM�Q�将�H�口�|�于Z序的底部。如果参数hWnd标识�?ji��n)一个顶层窗口，则窗口失去顶�U�位�|�，�q�且被置在其他窗口的底部�?nbsp; 　　
HWND_NOTOPMOST�Q�将�H�口�|�于所有非��层�H�口之上�Q�即在所有顶层窗口之后）(j��)。如果窗口已�l�是非顶层窗口则该标志不起作用�?nbsp; 　　
HWND_TOP:��窗口置于Z序的�剙��?nbsp; 　　
HWND_TOPMOST:��窗口置于所有非��层�H�口之上。即使窗口未被激�zȝ��口也��保持顶�U�位�|��?nbsp;
接下来四个参数是�H�口的位�|�和��寸�?br />最后一个参数nFlags是窗口显�C�方式的标志�Q�这个参数很多，可以�l�合使用�Q�详�l�如下：(x��)
SWP_ASNCWINDOWPOS�Q�如果调用进�E�不拥有�H�口�Q�系�l�会(x��)向拥有窗口的�U�程发出需求。这��防止调用线�E�在其他�U�程处理需求的时候发生死锁�?nbsp; 　　
SWP_DEFERERASE�Q�防止��生WM_SYNCPAINT消息�?nbsp; 　　
SWP_DRAWFRAME�Q�在�H�口周围��M��个边框（定义在窗口类描述中）(j��)�?nbsp; 　　
SWP_FRAMECHANGED�Q�给�H�口发送WM_NCCALCSIZE消息�Q�即使窗口尺寸没有改变也�?x��)发送该消息。如果未指定�q�个标志�Q�只有在改变�?ji��n)窗口尺寸时才发送WM_NCCALCSIZE�?nbsp;
SWP_HIDEWINDOW;隐藏�H�口�?nbsp;
SWP_NOACTIVATE�Q�不�Ȁ�zȝ��口。如果未讄��标志�Q�则�H�口被激�z�，�q�被讄��到其他最高��H�口或非最高��l�的�剙��Q�根据参数hWndlnsertAfter讄��Q��?nbsp;
SWP_NOCOPYBITS�Q�清除客户区的所有内宏V��如果未讄��该标志，客户区的有效内容被保存�ƈ且在�H�口��寸更新和重定位后拷贝回客户区�?nbsp;
SWP_NOMOVE�Q�维持当前位�|�（忽略X和Y参数�Q��?nbsp; 　　
SWP_NOOWNERZORDER�Q�不改变z序中的所有者窗口的位置�?nbsp;
SWP_NOREDRAW:不重��L��变的内容。如果设�|�了(ji��n)�q�个标志�Q�则不发生�Q何重��d��作。适用于客户区和非客户区（包括标题栏和滚动条）(j��)和�Q何由于窗回移动而露出的父窗口的所有部分。如果设�|�了(ji��n)�q�个标志�Q�应用程序必��L��地使窗口无效�ƈ重画�H�口的�Q何部分和父窗口需要重�ȝ��部分�?nbsp;
SWP_NOREPOSITION�Q�与SWP_NOOWNERZORDER标志相同�?nbsp; 　 SWP_NOSENDCHANGING�Q�防止窗口接收WM_WINDOWPOSCHANGING消息�?nbsp;
SWP_NOSIZE�Q�维持当前尺寸（忽略cx和Cy参数�Q��?nbsp;
SWP_NOZORDER�Q�维持当前Z序（忽略hWndlnsertAfter参数�Q��?nbsp;
SWP_SHOWWINDOW�Q�显�C�窗口�?br />注意事项�Q?br />使用SetWindowPos()如果讄��?ji��n)SWP_SHOWWINDOWS或者SWP_HIDEWINDOW�Q�那么窗口将不能被移动和改变大小�Q�我使用时就是设�|�了(ji��n)SWP_SHOWWINDOW,从而导致不能重�l�背景�?br />
两者的比较�Q?br />两者都能实现移动和改变�H�口大小�?br />
MoveWindow()功能比较单一�Q�只能移动和改变�H�口大小�Q�而SetWindowPos()可以讄��更多的参敎ͼ�实现Zorder�?qi��ng)显�C�方式标志�?br />
MoveWindow()发送WM_WINDOWPOSCHANGING�Q�W(xu��)M_WINDOWPOSCHANGED�Q�W(xu��)M_MOVE�Q�W(xu��)M_SIZE和W(xu��)M_NCCALCSIZE�{�消息到�H�口�Q�SetWindowPos()只发送WM_WINDOWPOSCHANGED消息到窗口。所以说如果需要发送更多消息时�q�是使用MoveWindow()的好�?/span>

VC中编�E�对于刚刚开始学�?f��n)的同学�Q�最大的障碍和问题就是消息机制和指针获取与操作。其实这些内容基本上是每本VC学习(f��n)工具书上必讲的内容，而且通过MSDN很多问题都能解决。下面文字主要是个�h在编�E�中指针使用的一些体�?x��)，说的不当的地方请指正。一般我们��用的框架是VC提供的Wizard生成的MFC App Wizard(exe)框架�Q?nbsp;
无论是多文档�q�是单文档，都存在指针获取和操作问题。下面这节内容主要是一般的框架�Q�然后再讲多�U�程中的指针使用。��用到的类需要包含响应的头文件。首先一般获得本�c?视，文档�Q�对话框都支�?实例指针this�Q�用this的目的，主要可以通过�c�M��的函数向其他�c�L��者函��C��发指针，以便于在非本�c�M��操作和��用本�c�M��?nbsp;
功能�?nbsp;

1�Q?nbsp;在View中获得Doc指针 CYouSDIDoc *pDoc=GetDocument();一个视只能有一个文档�?nbsp;
2) 在App中获得MainFrame指针
CWinApp 中的 m_pMainWnd变量��是MainFrame的指�?nbsp;
也可以：(x��) CMainFrame *pMain =(CMainFrame *)AfxGetMainWnd();
3) 在View中获得MainFrame指针 CMainFrame *pMain=(CmaimFrame *)AfxGetApp()->m_pMainWnd;
4) 获得View�Q�已建立�Q�指针CyouView *pView=(CyouView *)pMain->GetActiveView();
5) 获得当前文档指针 CDocument * pCurrentDoc =(CFrameWnd *)m_pMainWnd->GetActiveDocument();
6) 获得状态栏与工��h��指针 CStatusBar * pStatusBar�Q?CStatusBar *)AfxGetMainWnd()->GetDescendantWindow(AFX_IDW_STATUS_BAR);
CToolBar * pToolBar=(CtoolBar *)AfxGetMainWnd()->GetDescendantWindow(AFX_IDW_TOOLBAR);

7) 如果框架中加入工��h��和状态栏变量�q�可以这�?nbsp;
(CMainFrame *)GetParent()->m_wndToolBar;
(CMainFrame *)GetParent()->m_wndStatusBar;

8) 在Mainframe获得菜单指针
CMenu *pMenu=m_pMainWnd->GetMenu();

9) 在�Q何类中获得应用程序类
用MFC全局函数AfxGetApp()获得�?nbsp;

10) 从文档类取得视图�cȝ��指针
CDocument�c�L��供了(ji��n)两个函数用于视图�cȝ��定位�Q?nbsp;
GetFirstViewPosition()和GetNextView()
virtual POSITION GetFirstViewPosition() const;
virtual CView* GetNextView(POSITION& rPosition) const;

注意�Q�GetNextView()括号中的参数用的是引用方式，因此执行后值可能改变�?nbsp;
GetFirstViewPosition()用于�q�回�W�一个视图位�|�（�q�回的�ƈ非视囄��指针�Q�而是一个POSITION�c�d��|��(j��)�Q�GetNextView()有两个功能：(x��)�q�回下一个视囄��的指针以�?qi��ng)用引用调用的方式来改变传入的POSITION�c�d��参数的倹{��很明显�Q�在Test�E�序中，只有一个视囄��Q�因此只需��这两个函数调用一�ơ即可得到CTestView的指针如下（需定义一个POSITION�l�构变量来辅助操作）(j��)�Q?nbsp;
CTestView* pTestView;
POSITION pos=GetFirstViewPosition();
pTestView=GetNextView(pos);

�q�样�Q�便可到�?ji��n)CTestView�cȝ��指针pTestView.执行完几句后�Q�变量pos=NULL,因�ؓ(f��)没有下一个视囄��Q�自然也没有下一个视囄��的POSITION.但是�q�几条语句太��单，不具有太强的通用性和安全特征�Q�当象前面说的那��P��当要在多个视图�ؓ(f��)中返回某个指定类的指针时�Q�我们需要遍历所有视囄��Q�直到找到指定类为止。判断一个类指针指向的是否某个类的实例时�Q�可用IsKindOf()成员函数时行��(g��)查，如：(x��)
pView->IsKindOf(RUNTIME_CLASS(CTestView));
卛_��(g��)查pView所指是否是CTestView�c�R�?nbsp;

有了(ji��n)以上基础�Q�我们已�l�可以从文档�c�d��得�Q何类的指针。�ؓ(f��)�?ji��n)方便，我们��其作��?f��)一个文档类的成员函敎ͼ�它有一个参敎ͼ�表示要获得哪个类的指针。实现如下：(x��)
CView* CTestDoc::GetView(CRuntimeClass* pClass)
{
    CView* pView;
    POSITION pos=GetFirstViewPosition();
    while(pos!=NULL) {
      pView=GetNextView(pos);
      if(!pView->IsKindOf(pClass))
        break;
    }

    if(!pView->IsKindOf(pClass)) {
        AfxMessageBox("Connt Locate the View.\r\n");
        return NULL;
    }
    return pView;
}

其中用了(ji��n)两次视图�cȝ��成员函数IsKindOf()来判断，是因为退出while循环有三�U?nbsp;
可能�Q?nbsp;
1.pos为NULL�Q�即已经不存在下一个视囄��供操作；
2.pView已符合要求�?nbsp;

1�?同是满��。这是因为GetNextView()的功能是��当前视图指针改变成一个视囄��位置同时�q�回当前视图指针�Q�因此pos是pView的下一个视囄��的POSITION,完全有可能既是pos==NULL又是pView�W�合需要。当所需的视图是最后一个视图是最后一个视囄��时就如引。因此需采用两次判断�?nbsp;使用该函数应遵��@如下格式�Q�以取得CTestView指针��Z��Q�：(x��)
CTestView* pTestView=(CTestView*)GetView(RUNTIME_CLASS(CTestView));
RUNTIME_CLASS是一个宏�Q�可以简单地理解它的作用�Q�将�cȝ��名字转化�?nbsp;
CRuntimeClass为指针。至于强制类型�{换也是�ؓ(f��)�?ji��n)安全特性考虑的，因�ؓ(f��)从同一个基�c�M��间的指针�c�d��是互相兼容的。这�U�强制类型�{换也许�ƈ不必要，但能避免一些可能出现的�ȝ��(ch��)�?nbsp;

3.从一个视囄��取得另一视图�cȝ��指针 �l�合1�?�Q�很�Ҏ(gu��)��得出视图�c�M��间互相获得指针的�Ҏ(gu��)��Q�就是用文档�c�M��中�{�Q�先�?的方法得到文档类的指针，再用2的方法，以文档类的视囑֮�位函数取得另一个视囄��。同��P��可以实现成一个函敎ͼ�(x��)
�Q�假设要从CTestAView中取得指向其它视囄��的指针）(j��)
CView* CTestAView::GetView(CRuntimeClass* pClass)
{
CTestDoc* pDoc=(CTestDoc*)GetDocument();
CView* pView;
POSITION pos=pDoc->GetFirstViewPosition();
while(pos!=NULL){
pView=pDoc->GetNextView(pos);
if(!pView->IsKindOf(pClass))
break;
}
if(!pView->IsKindOf(pClass)){
AfxMessageBox("Connt Locate the View.");
return NULL;
}
return pView;
}
�q�个函数�?中的GetView()相比�Q�一是多�?ji��n)第一句以取得文档�c�L��针，二是在GetFirstViewPosition()和GetNextView()前加上了(ji��n)文档�c�L��针，以表�C�它们是文档
�c�L��员函数。有�?ji��n)此函数�Q�当要从CTestAView中取得CTestBView的指针时�Q�只需如下�Q�CTestBView* pTestbView=(CTestView*)GetView(RUNTIME_CLASS(CTestBView));

11�Q�对于单文档中也可以加入多个文档模板�Q�但是一般的开发就使用MDI方式开发多文档模板�Q�其�Ҏ(gu��)��与上�q�视囄��获取�Ҏ(gu��)��很接�q�，�q�里�E�做解释�Q�如果不清楚�Q�请查阅MSDN

可以用CWinApp::GetFirstDocTemplatePostion获得应用�E�序注册的第一个文档模�?nbsp;
的位�|�；利用该值来调用CWinApp::GetNextDocTemplate函数�Q�获得第一个CDocTemplate对象指针�?nbsp;
POSITION GetFirstDocTemplate( ) const;
CDocTemplate *GetNextDocTemplate( POSITION & pos ) const;

�W�二个函数返回由pos 标识的文档模�ѝ��POSITION是MFC定义的一个用于�P代或对象指针��(g��)索的倹{��通过�q�两个函敎ͼ�应用�E�序可以遍历整个文档模板列表。如果被��(g��)索的文档模板是模板列表中的最后一个，则pos参数被置为NULL�?nbsp;

12�Q�一个文档模板可以有多个文档�Q�每个文档模杉K��保留�q�维护了(ji��n)一个所有对应文档的指针列表�?nbsp;
用CDocTemplate::GetFirstDocPosition函数获得与文档模板相关的文档集合中第一个文档的位置�Q��ƈ用POSITION��g��为CDocTemplate::GetNextDoc的参数来重复遍历与模板相关的文档列表。函数原形�ؓ(f��)�Q?nbsp;
viaual POSITION GetFirstDocPosition( ) const = 0;
visual CDocument *GetNextDoc(POSITION & rPos) const = 0;
如果列表为空�Q�则rPos被置为NULL.

13�Q�在文档中可以调用CDocument::GetDocTemplate获得指向该文档模板的指针�?nbsp;
函数原�Ş如下�Q?nbsp;CDocTemplate * GetDocTemplate ( ) const;
如果该文档不属于文档模板��理�Q�则�q�回��gؓ(f��)NULL�?nbsp;

14)一个文档可以有多个视。每一个文档都保留�q�维护一个所有相兌��的列表�?nbsp;
CDocument::AddView��一个视�q�接到文档上�Q�将该视加入到文档相联系的视的列表中�Q��ƈ��视的文档指针指向该文档。当有File/New、File/Open、Windows/New或Window/Split的命令而将一个新创徏的视的对象连接到文档上时�Q?nbsp;MFC�?x��)自动调用该函数�Q�框枉��过文档/视的�l�构��文档和视联�p��v来。当�?d��ng)��E�序员也可以�Ҏ(gu��)��自己的需要调用该函数�?nbsp;
Virtual POSITION GetFirstViewPosition( ) const;
Virtual CView * GetNextView( POSITION &rPosition) cosnt;

应用�E�序可以调用CDocument::GetFirstViewPosition�q�回与调用文档相联系的视的列表中的第一个视的位�|�，�q�调用CDocument::GetNextView�q�回指定位置的视�Q��ƈ��rPositon的值置为列表中下一个视的POSITION倹{��如果找到的视�ؓ(f��)列表中的最后一个视�Q�则��rPosition�|��ؓ(f��)NULL.

15)从一个视囄��取得另一视图�cȝ��指针
�q�个应用在多视的应用�E�序中很多见�Q�一般如果自己在�ȝ��序或者主框架中做好变量记��P��也可以获得，�q�有比较通用的就是用文档�c�M��中�{�Q�以文档�cȝ��视图遍历
定位�Q�取得另一个视囄��。这个功能从本文�W?0��中可以得到�?nbsp;

�H�口销毁的相关函数与消�?/div>

DestroyWindow函数

DestroyWindow销毁窗口的正牌函数�?/div>

DestroyWindows的MSDN说明如下�Q?/div>

The DestroyWindow function destroys the specified window. The function sends WM_DESTROY and WM_NCDESTROY messages to the window to deactivate it and remove the keyboard focus from it. The function also destroys the window's menu, flushes the thread message queue, destroys timers, removes clipboard ownership, and breaks the clipboard viewer chain (if the window is at the top of the viewer chain).

If the specified window is a parent or owner window, DestroyWindow automatically destroys the associated child or owned windows when it destroys the parent or owner window. The function first destroys child or owned windows, and then it destroys the parent or owner window.

DestroyWindow also destroys modeless dialog boxes created by the CreateDialog function.

A thread cannot use DestroyWindow to destroy a window created by a different thread.

If the window being destroyed is a child window that does not have the WS_EX_NOPARENTNOTIFY style, a WM_PARENTNOTIFY message is sent to the parent.

DestroyWindow的处理过�E��ȝ��要点如下�Q?nbsp;

1. 向父�H�口发送WM_PARENTNOTIFY消息�Q�仅当窗口具有WS_EX_NOPARENTNOTIFY样式�Q�；

2. 向窗口发送WM_DESTROY消息�Q?nbsp;

3. 使窗口�{入非�z�d��状态，�U�除键盘焦点�Q?nbsp;

4. 销毁子�H�口�Q�应该是通过递归调用DestroyWindow完成�Q�；

5. 销毁目标窗口资源：(x��)销毁菜单，清空�U�程的消息队列，销毁与�H�口�q�程相关的定时器�Q�解除窗口对剪脓(chu��ng)板的拥有权，打断剪脓(chu��ng)板器的查看链�Q?nbsp;

6. 向窗口发送WM_NCDESTROY消息�Q?/div>

上述条目大致从前往后执行（1�?�?的顺序不一定，5�?的顺序不一定）(j��)。依据是�Q?nbsp;

1. �Ҏ(gu��)��WM_PARENTNOTIFY说明�Q�销毁窗口时�Q�系�l�在��M��销毁窗口的操作执行前发送WM_PARENTNOTIFY至父�H�口�Q?nbsp;

2. �Ҏ(gu��)��WM_DESTROY说明�Q�此消息先被发送至目标�H�口�Q�然后发送给目标�H�口的所有子�H�口�Q�处理此消息�Ӟ��可以假定所有子�H�口�q�存在着�Q?nbsp;

3. �Ҏ(gu��)��DestroyWindow说明�Q�函数先销毁子�H�口�?qi��ng)所拥有的窗口，然后销毁目标窗口；

4. �Ҏ(gu��)��WM_NCDESTROY说明�Q�与WM_DESTROY相反的是�Q�此消息在所有子�H�口销毁之后发送；没有�ȝ��汇编代码�Q�只是根据各个MSDN说明来大致推��的�Q�基本够用了(ji��n)吧�?/div>

�Ҏ(gu��)��MSDN说明�Q�不能在非创建线�E�上调用DestroyWindow�Q�若要在其它�U�程上关闭窗口，不可以直接调用DestroyWindow�Q�错�?拒绝讉K��"�Q�，也不可以只发送WM_DESTROY�Q�因为DestroyWindow才能完整的关闭窗口，W(xu��)M_DESTROY消息只是关闭��程的一部分�Q�甚��x��最"无用"的一部分--WM_DESTROY只是用户响应的接口，而真正清理窗口的工作由DestroyWindow的其它部分完成�?nbsp;

要在其它�U�程上关闭窗口，可以向窗口发送WM_CLOSE消息�Q�若�H�口�q�程未在WM_CLOSE的处理中取消关闭操作�Q�则DefWindowProc�?x��)默认调用DestroyWindow�Q�彼时自然是在窗口的创徏�U�程上）(j��)�?/div>

WM_CLOSE消息

WM_CLOSE的MSDN说明如下�Q?/div>

An application can prompt the user for confirmation, prior to destroying a window, by processing the WM_CLOSE message and calling the

DestroyWindow function only if the user confirms the choice.

By default, the DefWindowProc function calls the DestroyWindow function to destroy the window.

WM_CLOSE消息提供取消关闭�H�口操作的接口，也可以作为窗口关闭的兌��处理的统一入口。点�ȝ��口右上角的关闭按钮将��D��H�口收到WM_CLOSE消息�Q�一般情况下�Q�菜单中的Exit��的处理代码中也应向�H�口发送WM_CLOSE消息�Q�这样可以��无论何种方式触发的窗口关闭操作，其程序流均会(x��)��入WM_CLOSE消息的处理过�E�。在WM_CLOSE中可以对�E�序状态进行确认，自动或由用户��认是否取消关闭操作�?nbsp;

与接下来的其它消息相比，W(xu��)M_CLOSE的特�D�之处在于它发生在销毁过�E�启动之前。用户处理完W(xu��)M_CLOSE消息后，如未取消�Q�则DefWindowProc��调用DestroyWindow来关闭窗口，一旦进入DestroyWindow�Q�则关闭�q�程��不可逆�{�?/div>

WM_DESTROY消息

WM_DESTROY的MSDN说明如下�Q?/div>

The WM_DESTROY message is sent when a window is being destroyed. It is sent to the window procedure of the window being destroyed after the window is removed from the screen.

This message is sent first to the window being destroyed and then to the child windows (if any) as they are destroyed. During the processing of the message, it can be assumed that all child windows still exist.

A window receives this message through its WindowProc function.

If the window being destroyed is part of the clipboard viewer chain (set by calling the SetClipboardViewer function), the window must remove itself from the chain by processing the ChangeClipboardChain function before returning from the WM_DESTROY message.

最后一句值得注意�Q�不�q�对剪脓(chu��ng)板涉猎不多，暂且不究�?/div>

WM_PARENTNOTIFY消息

WM_PARENTNOTIFY的MSDN说明如下�Q?/div>

The WM_PARENTNOTIFY message is sent to the parent of a child window when the child window is created or destroyed, or when the user clicks a mouse button while the cursor is over the child window. When the child window is being created, the system sends WM_PARENTNOTIFY just before the CreateWindow or CreateWindowEx function that creates the window returns. When the child window is being destroyed, the system sends the message before any processing to destroy the window takes place.

A window receives this message through its WindowProc function.

WM_NCDESTROY消息

WM_NCDESTROY的MSDN说明如下�Q?/div>

The WM_NCDESTROY message informs a window that its nonclient area is being destroyed. The DestroyWindow function sends the WM_NCDESTROY message to the window following the WM_DESTROY message. WM_DESTROY is used to free the allocated memory object associated with the window. The WM_NCDESTROY message is sent after the child windows have been destroyed. In contrast, WM_DESTROY is sent before the child windows are destroyed. A window receives this message through its WindowProc function. This message frees any memory internally allocated for the window.

关于WM_DESTROY与WM_NCDESTROY�Q�从各种说明可以看出�Q�一个大�U�充当关闭操作启动时的通知接口�Q�一个大�U�充当关闭操作完成时的通知接口。这也是我认为在DestroyWindow的处理流�E�中�Q�第6条在�W?条之后的原因�?nbsp;

另外�Q�说明中有个值得一提的地方在于�Q�WM_DESTROY用于释放兌��刎ͼ�associated to�Q�窗口的已分配内存对象，W(xu��)M_NCDESTROY用于释放内部为窗口分配的�Q�internally allocated for�Q�内存�?可以惌��Q�后者应当指�H�口的内核数据，但前者则有各�U�可能，菜单资源�Q�GDI资源�Q�异或是子窗口资源？�q�个��׃��好说�?ji��n)�?而且�Q�根据这两句话的表述�Q�似乎这两个清理操作是在消息的处理过�E�中发生的，然而显然又不是��q��h��完成的工作，那么��应当是在DefWindowProc中完成的�?ji��n)。�ؓ(f��)什么不直接拿到Destroywindow中来执行呢？

ActiveX控�g的销�?/div>

销毁控件的最好方法是销毁宿�ȝ��口。可以通过调用 CWindow::DestroyWindow �?DestroyWindow API 昑ּ�地进行销毁，或者让宿主�H�口的父�U�窗口的毁坏��D��其死亡，从而隐式地�q�行销毁。这些方法的��M��一�U�都��安全地销毁寄宿的控�g。请注意�Q�CAxWindow 对象的毁�?不会(x��)"��D��基础"AtlAxWin7"�H�口的毁坏�?nbsp;

Win32讑֤�上下�?Device Contexts)

天下 — Tue, 04 Jun 2013 01:08:00 GMT

讑֤�上下�?讑֤�内容)

Device Contexts

A device context is a structure that defines a set of graphic objects and their associated attributes, as well as the graphic modes that affect output. The graphic objects include a pen for line drawing, a brush for painting and filling, a bitmap for copying or scrolling parts of the screen, a palette for defining the set of available colors, a region for clipping and other operations, and a path for painting and drawing operations. The remainder of this section is divided into the following three areas.

About Device Contexts

Device independence is one of the chief features of Microsoft Windows. Applications can draw and print output on a variety of devices. The software that supports this device independence is contained in two dynamic-link libraries. The first, Gdi.dll, is referred to as the graphics device interface (GDI); the second is referred to as a device driver. The name of the second depends on the device where the application draws output. For example, if the application draws output in the client area of its window on a VGA display, this library is Vga.dll; if the application prints output on an Epson FX-80 printer, this library is Epson9.dll.

An application must inform GDI to load a particular device driver and, once the driver is loaded, to prepare the device for drawing operations (such as selecting a line color and width, a brush pattern and color, a font typeface, a clipping region, and so on). These tasks are accomplished by creating and maintaining a device context (DC). A DC is a structure that defines a set of graphic objects and their associated attributes, and the graphic modes that affect output. The graphic objects include a pen for line drawing, a brush for painting and filling, a bitmap for copying or scrolling parts of the screen, a palette for defining the set of available colors, a region for clipping and other operations, and a path for painting and drawing operations. Unlike most of the structures, an application never has direct access to the DC; instead, it operates on the structure indirectly by calling various functions.

This overview provides information on the following topics:

Graphic Objects

Graphic Modes

Device Context Types

Device Context Operations

ICM-Enabled Device Context Functions

An important concept is the layout of a DC or a window, which describes the order in which GDI objects and text are revealed (either left-to-right or right-to-left). For more information, see "Window Layout and Mirroring" in Window Features and the GetLayout and SetLayout functions.

Device Context Types

There are four types of DCs: display, printer, memory (or compatible), and information. Each type serves a specific purpose, as described in the following table.

Device context Description

Display Supports drawing operations on a video display.

Printer Supports drawing operations on a printer or plotter.

Memory Supports drawing operations on a bitmap.

Information Supports the retrieval of device data.

讑֤�上下文是windows�~�程中最重要的概念之一。widnows下的所有绘��N��是通过讑֤�上下文进行的�?nbsp;

讑֤�上下文是一�U�包含有��x��个设备（如显�C�器或打印机�Q�的�l�制属性信息的 Windows 数据�l�构。所有绘制调用都通过讑֤�上下文对象进行，�q�些对象��装�?ji��n)用于绘制线条、�Ş状和文本�?Windows API。设备上下文允许�?Windows 中进行与讑֤�无关的绘制。设备上下文可用于绘制到屏幕、打印机或者图元文件�?/div>

DC与特定的昄��讑֤��Q�如昄��器或打印机）(j��)相关�?/div>

对于昄��器，DC��L��与显�C�器上的特定视窗相关�?/div>

DC中的有些值是囑�Ş「属性」，�q�些属性定义了(ji��n)GDI�l�图函数工作的细节�?/div>

例如�Q�对於TextOut�Q�DC的属性确定了(ji��n)文字的颜艌Ӏ�文字的背景艌Ӏ�x坐标和y坐标映射到视�H�的昄��区域的方式，以及(qi��ng)昄��文字时Windows使用的字体�?/div>

MSDN的解�? 一个DC是一个结构，它定义了(ji��n)一�p�d��囑�Ş对象的集合以�?qi��ng)它们相关的属性，以及(qi��ng)影响输出效果的一些图形模式。这些图形对象包括一个画�U�的�W�，一个填充和painting的画��P��一个用来向屏幕拯��的位图，一个定义了(ji��n)一�p�d��颜色集合的调色板�Q�一个用来剪裁等操作的区域，一个做painting和drawing操作的�\径�?/div>

最常用的取得�ƈ释放讑֤�上下文句柄的�Ҏ(gu��)��是，在处理WM_PAINT消息�Ӟ��使用BeginPaint和EndPaint呼叫�Q?/div>

hdc = BeginPaint (hwnd, &ps) ;

//do something

Windows�E�序�q�可以在处理非WM_PAINT消息时取得设备上下文句柄�Q?/div>

hdc = GetDC (hwnd) ;

//do something

ReleaseDC (hwnd, hdc) ;

Windows�E�序�q�可以取得适用于整个窗口（而不仅限于窗口的昄��区域�Q�的讑֤�上下文句柄：(x��)

hdc = GetWindowDC (hwnd) ;

//do something

ReleaseDC (hwnd, hdc) ;

�q�个讑֤�上下文除�?ji��n)显�C�区域之外，�q�包括窗口的标题列、菜单、滚动条和框�Ӟ��frame�Q�。GetWindowDC函数很少使用�Q�如果想��试用一用它�Q�则必须拦截处理WM_NCPAINT消息�Q�W(xu��)indows使用该消息在�H�口的非昄��区域上绘图�?/div>

BeginPaint、GetDC和GetWindowDC获得的设备上下文都与视讯昄��器上的某个特定窗口相兟뀂取得设备上下文句柄的另一个更通用的函数是CreateDC�Q?/div>

hdc = CreateDC (pszDriver, pszDevice, pszOutput, pData) ;

//do something

DeleteDC (hdc) ;

讑֤�上下文就是一个windows对象,即DC的句柄，而windows则是一�U�图形环境，其图形系�l��o(h��)人难以自信地灉|��和强大。而实质上�Q�widnows下的所有绘��N��是通过讑֤�上下文进行的�Q�而不是直接对�H�口和设备本�w�进行�?/div>

不带�~�存的I/O和标准I/O

天下 — Thu, 10 May 2012 08:53:00 GMT

不带�~�存的I/O和标准I/O

首先说说不带�~�存的I/O�Q�UNIX的文件I/O read、write是不带缓存的。不带缓存是指每个read、write都调用内核的一个系�l�调用，它们是POSIX.1的组成部分�?br />二者的原型为：(x��)
ssize_t read( int fd, void* buf, size_t nbytes ); // 若成功返回读到的字节�?/span>
ssize_t write( int fd, const void* buf, size_t nbytes ); // 若成功返回已写的字节�?/span>

注意�Q�上面的buf不是指read、write带缓存，而是当read时用来存放读出的字节�Q�write时存攑־�写的字节。对于read�Q�nbytes表示每次最多读的字节数。但�q�个块的大小��媄(ji��ng)响I/O的效率，其值和具体�pȝ��有关�?br />
补充一下，不带�~�存的I/O�Ҏ(gu��)��件描�q�符操作�Q�下面带�~�存的I/O是针�Ҏ(gu��)��的�?br />
标准I/O库就是带�~�存的I/O�Q�它由ANSI C标准说明。当�?d��ng)��标准I/O最�l�都�?x��)调用上面的I/O例程。标准I/O库代替用户处理很多细节，比如�~�存分配、以优化长度执行I/O�{��?br />
标准I/O提供�~�存的目的就是减��调用read和write的次敎ͼ�它对每个I/O��自动进行缓存管理（标准I/O函数通常调用malloc来分配缓存）(j��)。它提供�?ji��n)三�U�类型的�~�存�Q?br />
1) 全缓存。当填满标准I/O�~�存后才执行I/O操作。磁盘上的文仉��常是全�~�存的�?br />
2) 行缓存。当输入输出遇到新行�W�或�~�存满时�Q�才由标准I/O库执行实际I/O操作。stdin、stdout通常是行�~�存的�?br />
3) 无缓存。相当于read、write�?ji��n)。stderr通常是无�~�存的，因�ؓ(f��)它必��d��快输出�?br />
一般而言�Q�由�pȝ��选择�~�存的长度，�q�自动分配。标准I/O库在关闭��的时候自动释攄��存�?br />
在标准I/O库中�Q�一个效率不高的不��之处是需要复制的数据量。当每次使用行函数fgets和fputs�Ӟ��通常需要复制两�ơ数据：(x��)一�ơ是在内核和标准I/O�~�存之间�Q�当调用read和write�Ӟ��(j��)�Q�第二次是在标准I/O�~�存�Q�通常�pȝ��分配和管理）(j��)和用��L(f��ng)��序中的行�~�存�Q�fgets的参数就需要一个用戯��~�存指针�Q�之间�?br />
不管上面讲的到底懂没懂，��C��一点：(x��)

使用标准I/O例程的一个优�Ҏ(gu��)��无需考虑�~�存�?qi��ng)最佳I/O长度的选择�Q��ƈ且它�q�不比直接调用read、write慢多��?br />
带缓存的文�g操作是标准C 库的实现�Q�第一�ơ调用带�~�存的文件操作函数时标准库会(x��)自动分配内存�q�且��d��一�D�固定大��的内容存储在缓存中。所以以后每�ơ的��d��操作�q�不是针对硬盘上的文件直接进行的�Q�而是针对内存中的�~�存的。何时从��盘中读取文件或者向��盘中写入文件有标准库的机制控制。不带缓存的文�g操作通常都是�pȝ��提供的系�l�调用，更加低��Q�直接从��盘中读取和写入文�g�Q�由于IO瓉��的原因，速度�q�不如意�Q�而且原子操作需要程序员自己保证�Q�但使用得当的话效率�q�不差�?br />另外标准库中的带�~�存文�gIO 是调用系�l�提供的不带�~�存I(y��)O实现的�?br />
“术语不带�~�冲指的是每个read和write都调用内�怸�的一个系�l�调用。所有的��盘I(y��)/O都要�l�过内核的块�~�冲�Q�也�U�内核的�~�冲区高速缓存）(j��)�Q�唯一例外的是对原始磁盘设备的I/O。既然read或write的数据都要被内核�~�冲�Q�那么术�?#8220;不带�~�冲的I/O“指的是在用户的进�E�中对这两个函数不会(x��)自动�~�冲�Q�每�ơread或write��p��q�行一�ơ系�l�调用�?#8220;

How to move a dialog which does not have a caption(非标题栏�U�d��对话�?

天下 — Thu, 16 Feb 2012 02:24:00 GMT

How to move a dialog which does not have a caption

Introduction

This article is aimed at beginners, and presents two ways to move a dialog which does not have a caption by dragging its client area.

1. WM_SYSCOMMAND message

Sending the WM_SYSCOMMAND message starts the move operation. Add the following code to handle the mouse down event:

BEGIN_MSG_MAP(CMainDlg)
    //...
    MESSAGE_HANDLER(WM_LBUTTONDOWN, OnLButtonDown)
END_MSG_MAP()

LRESULT OnLButtonDown(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
    SendMessage(WM_SYSCOMMAND, SC_MOVE|HTCAPTION);
    return 0;
}

2. WM_NCHITTEST message

The idea is to handle the WM_NCHITTEST message to return HTCAPTION instead of HTCLIENT when the mouse is in the client area, to trick Windows to start moving the dialog.

BEGIN_MSG_MAP(CMainDlg)
    //...
    MESSAGE_HANDLER(WM_NCHITTEST, OnNcHitTest)
END_MSG_MAP()

LRESULT OnNcHitTest(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
    if (::DefWindowProc(m_hWnd, uMsg, wParam, lParam) ==
        HTCLIENT && ::GetAsyncKeyState(MK_LBUTTON) < 0)
      return HTCAPTION;

    return 0;
}

//For MFC
//Devil for ever supplied the MFC solution that is shown below (thanks!). The idea is the same - to handle the WM_NCHITTEST message.
UINT OnNcHitTest(CPoint point)
{
    UINT nHit = CDialog::OnNcHitTest(point);
    return (nHit == HTCLIENT ? HTCAPTION : nHit);
}
