Q 求救!!! 取ie浏览器文字乱码问题,高分相赠!!! 
T 我所写的一个程序中有这样一个功能:用户选取了ie浏览器中的一段文字copy到剪贴板,我的程序从剪贴板中取出文字并显示在edit框中,这在中文系统下没有任何问题,而当程序运行在英文日文98下时,ie中的中文字符从剪贴板中取后在edit框中显示为
乱码,edit框已设了MS Song体,能正确显示gb2312编码的汉字,估计ie中的中文为unicode什么的,我就想把它转为ascii码,但试了很多方法都不行.

if(OpenClipboard())
{
   if(IsClipboardFormatAvailable (CF_UNICODETEXT))
  {
    WCHAR *s;
    CString string;
    HANDLE handle=GetClipboardData(CF_UNICODETEXT);
    s=(WCHAR*)handle;
    string=s;
    string.TrimLeft();
    string.TrimRight();
    if(string!="")
   {
     char dest[256];
     len=string.GetLength();
     int len = WideCharToMultiByte(CP_ACP,0,s,len,dest,256,NULL,NULL);
     GetDlgItem(IDC_EDIT1)->SetWindowText(dest);//显示乱码
   }
   EmptyClipboard();
   CloseClipboard();
}

到底ie中的中文字符是什么编码,怎样转成gb2312,请各位高人指点,一定高分相赠!!!
A IMultiLanguage::ConvertStringFromUnicode Method

--------------------------------------------------------------------------------

Translates the source Unicode string to the specified multibyte code page.

Syntax

HRESULT ConvertStringFromUnicode(
    DWORD *pdwMode,
    DWORD dwEncoding,
    WCHAR *pSrcStr,
    UINT *pcSrcSize,
    CHAR *pDstStr,
    UINT *pcDstSize
);

Parameters

pdwMode
[in, out] Storage for conversion context. A calling function should only provide storage that is initialized with zero at the first call to the method. The caller should not modify the value.
dwEncoding
[in] Code page identifier value for the destination multibyte string. This value is equivalent to the uiCodePage member of the MIMECPINFO structure assigned to dwEncoding.
pSrcStr
[in] Address of the Unicode string that is to be converted.
pcSrcSize
[in, out] Address of the buffer that stores the length of the source string, in character counts. If this is NULL, or if -1 is specified as the length, the API assumes pSrcStr is null-terminated. When conversion is successful, the method returns the number of characters processed to this buffer.
pDstStr
[in] Address of the string buffer where the conversion result will be stored.
pcDstSize
[in, out] Address of the buffer that stores the length of pDstStr, in byte counts. When conversion is successful, the method returns the number of bytes copied to pDstStr to this buffer.
Return Value

Returns one of the following values:

S_OK Success. 
S_FALSE The specified conversion is not supported on the system. 
E_FAIL An error occurred. 

Remarks

Note that the size of the Unicode string to be converted is specified with a character count, while the size of the multibyte string returned is given in bytes.

Using IMultiLanguage2
 

To access the methods provided by IMultiLanguage2, a program must instantiate a MultiLanguage object and request the IMultiLanguage2 interface. This is can be done via the COM API CoCreateInstance. For example:

 

   hr = CoCreateInstance(

                           CLSID_CMultiLanguage, //Class identifier (CLSID) of the object

                           NULL,                                              //Pointer to controlling IUnknown

                           CLSCTX_INPROC_SERVER,   //Context for running executable code

                           IID_IMultiLanguage2 ,                  //Reference to the identifier of the interface

                           (void**) &pMultiLanguage2               //Address of output variable that receives

                                                                              // the interface pointer requested in riid

                           );

 

This call will return the address of the IMultiLanguage2 interface in pMultiLanguage2.

 

Note that if you are using Microsoft Visual C++ (MSVC) to create an IMultiLanguage2 client you will need to install a recent version of the Microsoft Platform SDK (the April 2000 version is sufficient). The Mlang.h and UUID.LIB that are supplied with MSVC itself do not support IMultiLanguage2.

 

Once the program has retrieved the interface pointer, it can then make calls into the IMultiLanguage2 API methods. For example:

 

    pMultiLanguage2->ConvertString(            pdwMode,

                                                            1252,

                                                            437,

                                                            pSrcStr,

                                                            pcSrcSize,

                                                            pDstStr,

                                                            pcDstSize

                                                            );

 

This call copies characters from the source buffer to the destination buffer while doing an encoding conversion from code page 1252 to code page 437.

 

One might wonder why Microsoft created this API when there’s a pair of perfectly good Win32 APIs that can be used to do the same thing: MultibyteToWideChar and WideCharToMultibyte. Not only can this pair of calls do what IMultiLanguage2::ConvertString can do, but also you can supply a number of additional options in the Win32 APIs to control the conversion more completely. In addition, the Win32 APIs return more useful error codes.

 

One reason might be the apparent inability of MultibyteToWideChar and WideCharToMultibyte to support popular Internet encodings like EUC‑KR and ISO‑2022‑JP on Windows NT 4 and Windows 95/98 even with the appropriate language pack installed. (There is no such limitation on Windows 2000.) Perhaps the Windows and IE development teams are finally in synch in this respect. However, at this writing, there are some useful options available via the MLang Converter object that are not available via the Win32 APIs (see below).

Q 关于网址过滤 
T 似乎用BHO可以控制IE,但是对ATL,COM还没怎么接触,哪位用过BHO的给讲解一下吧。111222的那篇我看过了,还是感觉不知道怎么开始。。。。
A BHO只对IE有效,除非你规定用户只能用IE或者你自己编写的浏览器,否则用户用其他浏览器可以绕过你的限制
另外一种方法是写一个防火墙……但是防火墙也是可以被绕过去的
要想真正屏蔽一个站点,可以使用屏蔽某搜索引擎时使用的方法

是从中国电信的出国网关那里做文章……你的办法可能只对基于IE的浏览器有效,但是你怎么禁止用户使用Netscape?

Browser Helper Objects: The Browser the Way You Want It

在函数
Invoke(DISPID dispidMember, REFIID riid, LCID lcid, WORD wFlags,
 DISPPARAMS* pDispParams, VARIANT* pvarResult,
    EXCEPINFO*  pExcepInfo,  UINT* puArgErr)
中捕获DISPID_BEFORENAVIGATE2事件,如果需要过滤网址的话,pDispParams取得第五个参数并判断(参见BEFORENAVIGATE2事件的文档)并适当设置第一个参数(参见BEFORENAVIGATE2事件的文档)

注意看Browser Helper Objects: The Browser the Way You Want It的这一段

By calling the IConnectionPoint's Advise() method, the BHO lets the browser know that it is interested in receiving notifications about events. Due to the COM event-handling mechanism, all this actually means that the BHO provides the browser with a pointer to its IDispatch interface. The browser will then call back the IDispatch's Invoke() method, passing the ID of the event as the first argument.

HRESULT CViewSource::Invoke(DISPID dispidMember, REFIID riid,
   LCID lcid, WORD wFlags, DISPPARAMS* pDispParams,
   VARIANT* pvarResult, EXCEPINFO* pExcepInfo, UINT* puArgErr)
{
  if (dispidMember == DISPID_DOCUMENTCOMPLETE) {
      OnDocumentComplete();
      m_bDocumentCompleted = true;
  }
  :
}

It's important to remember to disconnect from the browser when events are no longer needed. If you forget to do this, the BHO will remain locked even after you close the browser's window. (Among other things, this means you can't recompile or delete the object.) A good time to disconnect is when you receive the OnQuit event.

Extending the Dynamic HTML Object Model
It is possible for the hosting application to extend the Dynamic HTML Object Model so that scripts can refer to functionality implemented by the host. Such scripts refer to the host by specifying the external object that is available from the window object. For example, a reference to "window.external.speech" will call the host to resolve the name "speech." All standard script within the document will be executed normally.

This extension mechanism is implemented in the host by providing an IDispatch interface for the object model extension that will have IDispatch::GetIDsOfNames and IDispatch::Invoke called on it to resolve any references to the external object. The IDispatch that the host provides is obtained by the WebBrowser Control or MSHTML component by calling the host's IDocHostUIHandler::GetExternal method.

For an example of how to extend the Dynamic HTML Object Model, see the Driller Sample Source Page

Q 急!!!!!关于IE控件 500分相送!!! 
T 请问我已经得到IHTMLDocument2 如何把它显示到CWebBrowser2控件中呢?
A query IPersistStream for HtmlDocument object,and then call IPersistStream::Load from a memory stream created by CreateStreamOnHGlobal.

1 Create a WebBrowser host in Microsoft Visual C++ 6.0 or 7.0. For a sample implementation that uses the Active Template Library (ATL), see the following Microsoft Developer Network (MSDN) Web site:

Web and Internet Samples: ATLBrowser
http://msdn.microsoft.com/downloads/samples/internet/default.asp?url=/Downloads/samples/Internet/browser/atlbrowser/Default.asp

2 Sink DWebBrowserEvents2 on the WebBrowser control. For more information about sinking WebBrowser events, see the following MSDN Web site:


Reusing the WebBrowser Control: Working with WebBrowser Events
http://msdn.microsoft.com/library/default.asp?url=/workshop/browser/webbrowser/webbrowser.asp

3 When your application is created, call the IWebBrowser2 Navigate() method to move the WebBrowser to "about:blank".


4 Add code to your DWebBrowserEvents2::DocumentComplete() event handler to load a file from memory:


    If (m_bInitial)  //m_bInitial is used to prevent the DocumentComplete event from being fired recursively, set it to TRUE
after the Navigate() call.
    {
        HRESULT hr = E_FAIL;

        CComPtr spStream;
        DWORD dwWritten = 0;
        DWORD dwBytes = 0;

        HANDLE handle = CreateFile("c://temp//test.htm", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
        if (handle != INVALID_HANDLE_VALUE)
        {
                TCHAR szBuffer[10240];
                DWORD dwBytesRead;

                if (ReadFile(handle, szBuffer, sizeof(szBuffer) - 1, &dwBytesRead, NULL))
                {
                    szBuffer[dwBytesRead] = '/0';
                    CloseHandle(handle);
       
                    if (SUCCEEDED(CreateStreamOnHGlobal(NULL, TRUE, &spStream))) {
                        dwBytes = lstrlenA(szBuffer) + 1;
                        dwWritten = 0;
                        hr = spStream->Write(szBuffer, dwBytes, &dwWritten);
                        LARGE_INTEGER li = {0, 0};
                        spStream->Seek(li, STREAM_SEEK_SET, NULL);

                        CComPtr spDispatch;
                        hr = m_pWebBrowser->get_Document(&spDispatch);
       
                        if (SUCCEEDED(hr)) {
                            CComQIPtr spPersistStreamInit(spDispatch);
                            if (spPersistStreamInit != NULL) {
                                hr = spPersistStreamInit->InitNew();
                                if (SUCCEEDED(hr)) {
                                    hr = spPersistStreamInit->Load(spStream);
                                }
                           }
                      }
                 }
             }
         } 
    }
    m_bInitial = FALSE;

#include "mshtml.h"
//在SourceView中填写HtmlView中网页的源程序
void CMainFrame::OnMethod2()
{
    IHTMLDocument2 *pHTMLDocument=NULL;
    IPersistStreamInit *pPSI=NULL;

    IStream *pStream=NULL;
    HGLOBAL  hHTMLText;

    if  (!(pHTMLDocument = (IHTMLDocument2*)m_pHtmlView->m_browser.GetDocument()))
 return;
 
    if  (FAILED(pHTMLDocument->QueryInterface(&pPSI)))
    {
//   pHTMLDocument->Release();
 return;
    }

    hHTMLText = GlobalAlloc(GMEM_FIXED, MAX_SIZE);
    CreateStreamOnHGlobal(hHTMLText, TRUE, &pStream);
    pPSI->Save(pStream, FALSE);

//   m_pSourceView->SetWindowText((char*)hHTMLText);

    long nEditLength = m_pSourceView->GetEditCtrl().GetWindowTextLength();
    m_pSourceView->GetEditCtrl().SetSel(0, nEditLength);
    m_pSourceView->GetEditCtrl().ReplaceSel("");
    char *pText = (char*)hHTMLText;
    long lHtmlLength = strlen(pText);
    CString str("");
    long n = 0;
    for (long i=0; i < lHtmlLength; i++)
    {
     if  (*pText != 0x0d && *pText != 0x0a)
     {
      str += *pText;
      pText++;
     }
     else
     {
      pText++;
      if  (*pText == 0x0a)
   pText++;
      str += "/r/n";
      nEditLength = m_pSourceView->GetEditCtrl().GetWindowTextLength();
      m_pSourceView->GetEditCtrl().SetSel(nEditLength, nEditLength);
      m_pSourceView->GetEditCtrl().ReplaceSel(str);
      str.Empty();
     }
    }

    pStream->Release();
    pPSI->Release();
//   pHTMLDocument->Release();
}

三、修改HTML源代码以改变网页的显示

    这部分比较有意思,可以当作是一个小的HTML编辑器,看看预演效果。特别的不是显示一个新文件,而是修改原来的HTML文件。
关键代码:

//根据SourceView里的HTML文本改变HtmlView里的显示
void CMainFrame::OnChangehtml()
{
 IHTMLDocument2 *pHTMLDocument=NULL;
 IPersistStreamInit *pPSI=NULL;

 IStream *pStream=NULL;
 HGLOBAL  hHTMLText;

 if (!(pHTMLDocument = (IHTMLDocument2*)m_pHtmlView->m_browser.GetDocument()))
  return;
 
 if (FAILED(pHTMLDocument->QueryInterface(&pPSI)))
 {
//  pHTMLDocument->Release();
  return;
 }

 pHTMLDocument->clear();
 pPSI->InitNew();

 LPCTSTR strText = m_pSourceView->LockBuffer();
 DWORD dwLength = strlen(strText);
 hHTMLText = GlobalAlloc(GMEM_FIXED, dwLength);
 memset(hHTMLText, 0, dwLength);
 memcpy(hHTMLText, strText, dwLength);
 m_pSourceView->UnlockBuffer();
 CreateStreamOnHGlobal(hHTMLText, TRUE, &pStream);
 ULARGE_INTEGER libNewSize;
 libNewSize.QuadPart = dwLength;
 pStream->SetSize(libNewSize);这一步必须要,否则显示时会有多余字符出现
 pPSI->Load(pStream);

 pStream->Release();
 pPSI->Release();
// pHTMLDocument->Release();
}
Q 请问 ie如何实现复制文字到剪贴板中?

Q    包含IE控件的问题(如何得到IE页面输入值) 
T 我想做一个包含IE控件的程序,然后在这个控件的页面上有几个文本框。

请问:当这个页面提交时,我如何得到文本框中输入的值?
A BOOL CDlgEdit::SaveData()
{
 _variant_t varVal;
 try{
  //given id?
  if(m_varItemID.vt!=VT_CLSID){
   //new record,add new
   m_rst->AddNew();
  }
  FieldsPtr pFields=m_rst->Fields;
  FieldPtr pItem;
  CString strFieldName;
  long lFields=pFields->Count;
  //for each field
  for(long i=0;i   pItem=pFields->Item[i];
   strFieldName=(LPCTSTR)pItem->Name;
   IHTMLInputTextElementPtr pElement;
   //get html element by id
   GetElementInterface(strFieldName,IID_IHTMLInputTextElement,reinterpret_cast (&pElement));
   if(pElement){
    CComBSTR bstrFieldValue;
    pElement->get_value(&bstrFieldValue);
    //if natural data type
    CString strDataType=DataTypeGetFieldProperty(m_strDataType,strFieldName,"FieldType");
    //clear before use
    varVal=g_varEmpty;

    if(strDataType.IsEmpty()){//default translate
     g_SetValueString(varVal,_bstr_t(bstrFieldValue),g_AdoType2VARTYPE(pItem->Type));
    }
    else{//find alias or name
     g_SetValueString(varVal,_bstr_t(bstrFieldValue),strDataType,TRUE);
    }
    pItem->Value=varVal;
   }
  }  
  m_rst->Update();
 }
 catch(_com_error &e){
  ESErrPrintProviderError(g_connection);
  ESErrPrintComError(e); 
  return FALSE;
 }
 return TRUE;
}

说明
m_strDataType 编辑对象的数据类型
m_varItemID 编辑对象的ID(VT_CLSID或者VT_NULL类型)
m_rst 编辑对象的记录集
GetElementInterface 获得HTML元素的函数,定义可以在我的文章http://www.csdn.net/Develop/read_article.asp?id=14752中找到
DataTypeGetFieldProperty 获得字段的数据类型
g_SetValueString 根据数据类型设置字段的值
g_AdoType2VARTYPE ADO数据类型和VARIANT数据类型的转换
ESErrPrintProviderError和ESErrPrintComError是从MSDN ADO的示例中的函数g_PrintProviderError和g_PrintComError改编而来

T 3Q!
A 8过以后这种问题还是直接贴出来让大家回答吧,一个人的意见不一定准确,大家一起来讨论比较好
你这个问题偶还想收藏的说,说不定什么时候还有用(主要是下次抢分的时候直接贴链接用)
1 .  能否通过挂接事件连接点拦截脚本运行。如果可以是挂接哪一个接口。
    在IE对脚本进行解释运行前,IE插件能够得到通知,并能够阻止它运行。
    就像实现IShellExecuteHook接口拦截外壳程序运行一样。
2.  通过调用IHTMLElement的get_innerText,可以得到嵌入元素的整个文本。
   那么怎么得到该文本中鼠标下的那个单词呢?
Q 关于web控件在使用时的一个小问题,如何过滤掉提示信息对话框? 
T 使用web控件,通过该控件浏览已经保存在硬盘上的网页内容。有的时候浏览器会提示“出现了运行时错误,是否需要调试?”或者“你查看的网页正在试图关闭窗口,是否关闭窗口?”。有谁知道答案,谢谢

Q DHTML应用于windows Applicatoin界面?!讨论! 
T
开发过基于MFC的windows程序设计的朋友都知道,MFC提供的窗体效果和windows本身一样,无法提供很丰富的表现形式,也没有办法随便更改,
虽然有一些界面组件和界面控件,例如cj60,activeSkin之类的,我觉得也不够灵活。

有没有直接用HTML做界面,利用DHTML内部元素与应用程序交互的可能性呢?我已经看到一些程序使用了这些技术,通过IHTMLDocument接口,通过HTML hook技术来进行交互。

可我很难在网上找到比较详尽的技术介绍,请问大家有什么自己的想法吗?!

Q 怎么得到IE容器包含的对象的服务的接口指针
T
我的IE页面:
CLASSID="CLSID:1546B217-B1B4-42A9-B954-003CEA26E0FC">




我页面上有一个我的p1控件,还有一个word服务器
我想用我的p1去操作11.doc的Word服务器。

我得到IE的IOleContainer容器接口,然后用IOleContainer::EnumObjects来枚举包含的对象。可以得到两个对象,一个是我自p1对象(可以得到IOleObject),一个却是iframe对象(能访问到IHTMLIFrameElement),但得到IHTMLIFrameElement后怎么也得到对应word的IOleObject或理Word对象_Documnet这些接口。

我又用另一种方式,我先得到页面的IHTMLDocument2,再得到p2的IHTMLElement,但还是不能进而得到Word对象。

有哪们大虾告诉我怎么才得到到IE容器内的Word对象接口?我500分谢。
A 使用Frame对象的IWebbrowser2接口(可以从IHTMLElement或者IHTMLIFrameElement查询)的document属性可以获得word.appacation对象的IDispatch接口

The hyperlink object
A hyperlink object implements the IHlink interface and encapsulates four pieces of reference information: a moniker to the hyperlink target; a string for the location within the target; a friendly name for the target; and additional parameters.

The hyperlink object completely encapsulates the behavior of navigating to a referenced location. It also supports the ability to save and load itself through the IPersistStream interface, and the ability to be transferred through the clipboard or through drag-and-drop operations by means of IDataObject. A standard hyperlink object implementation is provided with the system, and it is not advisable to implement another version. A document can use the standard hyperlink object to represent hyperlinks within itself, thus encapsulating the work of navigating, saving, loading, dragging, dropping, cutting, and pasting hyperlinks. Standard hyperlink objects are created through the HlinkCreateFromData, HlinkCreateFromMoniker, HlinkCreateFromString, and OleLoadFromStream functions. The standard hyperlink object implements the IHlink, IPersistStream, and IDataObject interfaces.

IHlink::GetHlinkSite Method

The hyperlink container
A hyperlink container is a document or application that contains hyperlinks. The container supports hyperlinks by implementing the IHlinkSite interface and, if the container's objects can be targets of other hyperlinks, the IHlinkTarget interface.

Note   Generally, an object that acts as a hyperlink container can also act as a hyperlink target. An HTML page, for example, can contain a number of hyperlinks to other pages, while at the same time it can be the target of hyperlinks from other HTML pages.
The hyperlink site
A hyperlink site is a COM object that implements the IHlinkSite interface and supplies either the moniker or interface identifier of its hyperlink container. One hyperlink site can serve multiple hyperlinks. The moniker supplied by the hyperlink site is used to evaluate relative monikers to the hyperlink target. If the relative moniker is NULL, the target of the link is in the same container object, and IHlink::Navigate can result in an efficient internal jump

Note   The standard hyperlink object performs internal jumps by retrieving the container's IHlinkTarget moniker using IHlinkTarget::GetMoniker (which avoids an unnecessary moniker bind). The object then asks the container to navigate directly through the IHlinkTarget::Navigate method

anchors Property (IHTMLDocument2)

--------------------------------------------------------------------------------

Retrieves an interface pointer to a zero-based collection of all the A objects in an HTML document. The elements are in the same order as they appear in the document.

Syntax

HRESULT IHTMLDocument2::get_anchors(IHTMLElementCollection **p);
activeElement Property (IHTMLDocument2)

--------------------------------------------------------------------------------

Retrieves the object that has the focus when the parent document has focus.

Syntax

HRESULT IHTMLDocument2::get_activeElement(IHTMLElement **p);
Parameters

p
Address of a pointer to an IHTMLElement interface that receives the element that has the focus.
Return Value

Returns S_OK if successful, or an error value otherwise.
Remarks

Set the active element with the setActive or focus methods. Using the setActive method has no effect on document focus. Using the focus method on an individual element causes the element to gain focus and become the active element.

The active element remains the active element even when focus has been placed outside the parent document. If no particular object is given focus when focus returns to the parent document, then the active element will gain focus. Select the title bar of a different application and then select the initial browser title bar to confirm this. Focus is shifted to the other application initially, but returns to the same active element as before the selection

HOWTO: Get IHTMLDocument2 from a HWND

Q249232


--------------------------------------------------------------------------------
The information in this article applies to:

Microsoft Internet Explorer (Programming) versions 4.0, 4.01, 4.01 SP1, 4.01 SP2, 5, 5.5


Q
I use the Active Accessibility SDK to obtain an IHTMLDoc-ument2 pointer from a window handle (HWND). Is there any way to obtain an IWebBrowser2 pointer from the IHTMLDocument2 pointer? I抳e tried QueryInterface on both the document pointer as well as the IHTMLWindow2 pointer without results. I also tried the IOmNavigator * from get_navigator on the HTMLWindow2 pointer. Any ideas?

A
This is a common cause for COM consternation. You have the window, document, or browser and you know you should be able to get the others, but everywhere you turn, QueryInterface delivers a big fat NULL. The answer lies in the mysterious IServiceProvider whose job it is, well, to provide services. IServiceProvider is a great interface: it has only one method, QueryService. If you抮e using ATL smart pointers, it looks like this. First, you have to get the IServiceProvider.

CComQIPtr isp = pIHTMLDocument2;

This does a QueryInterface on the document for IServiceProvider. Once you have it, you can get the browser like so.

CComQIPtr iwb2;
isp->QueryService(IID_IWebBrowserApp,
    IID_IWebBrowser2, (void**)&iwb2);

      If all this seems confusing, there抯 a good reason for it. A cardinal rule of COM is that QueryInterface must always return an interface to the object queried. But the document doesn抰 implement IWebBrowser2; it only knows how to get the object that does. The document, browser, and window are all separate objects. In general, IServiceProvider is used whenever a bunch of separate but related COM objects together implement some kind of service. QueryInterface asks an object, do you implement this interface? QueryService tells a service provider, "get me whatever object implements this interface, please." With QueryService, the interface pointer returned may or may not be the same object as the one queried. Figure 6 illustrates the system. All the objects implement their various interfaces and store internal pointers to one another; IServiceProvider is your way to get whichever object implements a particular interface. IServiceProvider::QueryService chases the internal pointers to retrieve the object that implements the interface you want.


Figure 6 Many Objects, One IServiceProvider

      IServiceProvider is essential for navigating the DHTML object hierarchy. Say you抮e writing an ActiveX® control and you want to navigate the object model. How do you do it? First, query your IOleClientSite for IServiceProvider like so:

CComQIPtr isp = pSite;

then, once you have IServiceProvider, you can QueryService it for the application object.

CComQIPtr iwba;
isp->QueryService(IID_IWebBrowserApp,
    IID_IWebBrowserApp, (void **)&iwba);

Now you can navigate the object hierarchy (the app object is at the top). If you want the Web browser, it抯 the same as before.

CComQIPtr iwb2;
isp->QueryService(IID_IWebBrowserApp,
 IID_IWebBrowser2, (void **)&iwb2));

      In all these examples, SID_SWebBrowserApp identifies the service, but you抣l often see code that uses IID_IWebBrowserApp as the service ID. Either will work, since #defines SID_SWebBrowserApp to IID_IWebBrowserApp, but for programming pedants SID_SWebBrowserApp is technically more correct, and more clear to anyone reading your code.
      By the way, if you抮e brave enough to implement some far-reaching colossal object system such as the DHTML object model (Lord help you!), then you should implement IServiceProvider too.

Q 如何获得对网页上按钮之类控制的消息?(在VC里)
T 如在里使用IE控件作浏览网站的东东时,如何得到对网页按钮的点击消息呢?
A
Receiving Element Events
Each element in the DHTML Object Model supports an outgoing HTMLElementEvents2 interface. This interface defines the events that an HTML element can fire. You implement this interface to provide an event sink, which is a Component Object Model (COM) object that implements an outgoing interface and is used as the mechanism for firing events.

Note  Interfaces implemented by a server usually have their methods called by the client, but to fire an event, the server calls the respective method on the client event sink. These interface are called outgoing interfaces. A COM object that implements an outgoing interface is also known as a connectable object.
The following steps are required to receive events from an outgoing interface:

Implement the event sink.

The event sink implements the appropriate outgoing interface and methods. Internet Explorer event interfaces are dispinterfaces, so calls to event methods are made through IDispatch::Invoke . This means that you only need to implement the IDispatch interface to handle events.

Determine if the server is a connectable object.

Call QueryInterface  to retrieve a pointer to the IConnectionPointContainer  interface.

Find the appropriate connection point.

Call the IConnectionPointContainer::FindConnectionPoint  method to find the connection point you need. For Internet Explorer WebBrowser Control events, such as DWebBrowserEvents2::DocumentComplete, this is DWebBrowserEvents2. For element events, this is HTMLElementEvents2. You can also call the IConnectionPointContainer::EnumConnectionPoints  to enumerate through all the connection points a server supports.

Advise the connection point that you want to receive events.

Using the IConnectionPoint  interface pointer returned in the previous step, call IConnectionPoint::Advise , passing the IUnknown  interface pointer of your event sink.

 
Note  The connectable object will use the IUnknown interface pointer to query the client for the event sink interface. If the event sink does not support the outgoing interface, Internet Explorer will query the client for the IDispatch interface.
When you no longer want to receive events, you can call the IConnectionPoint::Unadvise  method, passing the cookie you received from the call to IConnectionPoint::Advise

The following sample code demonstrates how to begin receiving HTML element events for an element on an HTML page.
void CMyClass::ConnectEvents(IHTMLElement* pElem)
{
    HRESULT hr;
    IConnectionPointContainer* pCPC = NULL;
    IConnectionPoint* pCP = NULL;
    DWORD dwCookie;

    // Check that this is a connectable object.
    hr = pElem->QueryInterface(IID_IConnectionPointContainer, (void**)&pCPC);

    if (SUCCEEDED(hr))
    {
        // Find the connection point.
        hr = pCPC->FindConnectionPoint(DIID_HTMLElementEvents2, &pCP);

        if (SUCCEEDED(hr))
        {
            // Advise the connection point.
            // pUnk is the IUnknown interface pointer for your event sink
            hr = pCP->Advise(pUnk, &dwCookie);

            if (SUCCEEDED(hr))
            {
                // Successfully advised
            }

            pCP->Release();
        }

        pCPC->Release();
    }
}
The following sample code demonstrates how you would detect the firing of an HTMLElementEvents2::onclick event in your implementation of IDispatch::Invoke.

Hide Example

STDMETHODIMP CEventSink::Invoke(DISPID dispidMember,
                                REFIID riid,
                                LCID lcid,
                                WORD wFlags,
                                DISPPARAMS* pdispparams,
                                VARIANT* pvarResult,
                                EXCEPINFO* pexcepinfo,
                                UINT* puArgErr)
{
    switch (dispidMember)
    {
        case DISPID_HTMLELEMENTEVENTS2_ONCLICK:
        OnClick();
        break;

        default:
        break;
    }

    return S_OK;
}
