This tutorial assumes that you already know how to program in C++ and know some information about ATL and COM. To work through this tutorial, you will need the following installed on your development machine:
1、Visual C++6 installed
2、RBDeskBand ATL Object Wizard (Version 2.0):http://www.codeproject.com/KB/atl/rbdeskband.aspx
3、CWindowImpl ATL Object Wizard:http://www.codeproject.com/KB/atl/rbcwindowimpl.aspx

引:免费教你开发IE插件Toolbar的文章可真是少见。还好我在codeproject里找到一篇。不过还是花了一天的时间才自己编写一个Google Search Toolbar。

  如果你下载了Internet Explorer Toolbar (Deskband) Tutorial的源代码后编译不通过,也不用奇怪,我就是耽搁在这些地方。先说说都有哪些编译问题。

  1.编译的问题
 
  如果遇到下面的问题,就说明commctrl.h的版本低。我们完全可以不用TBSTYLE_EX_MIXEDBUTTONS,用 TBSTYLE_EX_DRAWDDARROWS就行。另外的三个删掉,换成TBSTYLE_BUTTON | TBSTYLE_AUTOSIZE,这个问题就解决了。

error C2065: 'TBSTYLE_EX_MIXEDBUTTONS' : undeclared identifier
error C2065: 'BTNS_BUTTON' : undeclared identifier
error C2065: 'BTNS_AUTOSIZE' : undeclared identifier
error C2065: 'BTNS_SHOWTEXT' : undeclared identifier
  如果遇到下面问题,把工程文件(dsp)里面的/D _ATL_MIN_CRT删掉。

  如果你自己重新编写一个新的项目实现IE Toolbar的话,注意一下2个地方。

  1.注意CMFToolbar的消息映射顺序。CHAIN_MSG_MAP_MEMBER一定要在WM_CREATE的前面。

BEGIN_MSG_MAP(CToolbarWnd)
CHAIN_MSG_MAP_MEMBER(m_EditWnd)
MESSAGE_HANDLER(WM_CREATE, OnCreate)

END_MSG_MAP()
  2.注意CReflectionWnd的消息映射顺序。WM_CREATE一定要在CHAIN_MSG_MAP_MEMBER的前面。

BEGIN_MSG_MAP(CReflectWnd)
MESSAGE_HANDLER(WM_CREATE, OnCreate)
CHAIN_MSG_MAP_MEMBER(m_ToolbarWnd)
END_MSG_MAP()
  3.Google Search Toolbar


  codeproject有非常详细的开发步骤,在这里就不重复了。本节的目的是实现Google Search功能。创建ColimasBar工程,创建CColimasBar类,IE Plugin接口:

public CComObjectRootEx<CComSingleThreadModel>,
public CComCoClass<CColimasBar, &CLSID_ColimasBar>,
public IDeskBand,
public IInputObject,
public IObjectWithSite,
public IDispatchImpl<IColimasBar, &IID_IColimasBar, &LIBID_IEBASELib>
  创建CEditWnd类,输入栏控件,继承

public CWindowImpl<CEditWnd>
  创建CReflectWnd类,消息传递空间,继承

public CWindowImpl<CEditWnd>
  创建CToolbarWnd类,Toolbar控件,继承

public CWindowImpl<CEditWnd>
  修改Toolbar的Title:

const WCHAR TITLE_CColimasBar[] = L"Google";
  修改Button的Title:

TCHAR* pCaption = _T("Search!");
  增加Button点击事件的Google Search处理函数GetValue

void CToolbarWnd::GetValue()
{
 // if we have a web browser pointer then try to navigate to google site to retrieve search
 if (m_pBrowser)
 {
  VARIANT vEmpty;
  VariantInit(&vEmpty);
  m_pBrowser->Stop();
  _bstr_t bsSite;
  // if the user has entered url then append them to the edit
  if (m_EditWnd.GetWindowTextLength())
  {
   WCHAR *bstr = NULL;
   m_EditWnd.GetWindowText(&bstr);

   UINT i= WideCharToMultiByte(CP_UTF8,0,bstr,-1,NULL,0,NULL,NULL); //双字节转换
   char *strB=new char[i];
   WideCharToMultiByte (CP_UTF8,0,bstr,-1,strB,i,NULL,NULL); //转换为ASCII
   UINT len=i;
   char* tmp=new char[len*3];
   tmp[0]='/0';

   for(i=0;i<len-1;i++)
   {
    byte j= (unsigned char)strB[i]; sprintf(tmp,"%s%%%x",tmp,j); //转换为16进制。

   }

   bsSite = L"http://www.google.com/search?hl=zh-CN&q=";
   //Google Search字符串
   bsSite += tmp;
   bsSite += "&rls=com.microsoft:en-US&ie=utf8&oe=utf8";
   SysFreeString(bstr);
   delete[] strB;
  }
  else
   bsSite = "http://www.google.com/";
   // have the webrowser navigate to the site URL requested depending on user input.
   m_pBrowser->Navigate(bsSite, &vEmpty, &vEmpty, &vEmpty, &vEmpty);
 }
}
