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 ．编译的问题 如果遇到下面的问题就说明commctrlh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 C: TBSTYLE_EX_MIXEDBUTTONS : undeclared identifier error C: BTNS_BUTTON : undeclared identifier error C: BTNS_AUTOSIZE : undeclared identifier error C: 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 Linking Creating library ReleaseUMinDependency/MotleyFoollib and object ReleaseUMinDependency/MotleyFoolexp LIBCMTlib(crtobj) : error LNK: unresolved external symbol _main ReleaseUMinDependency/MotleyFooldll : fatal error LNK: unresolved externals Error executing linkexe MotleyFooldll error(s) warning(s) 如果你自己重新编写一个新的项目实现IE Toolbar的话注意一下个地方 ．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() ．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() ．Google Search Toolbar 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接口继承 public CComObjectRootEx public CComCoClass public IDeskBand public IInputObject public IObjectWithSite public IDispatchImpl 创建CEditWnd类输入栏控件继承 public CWindowImpl 创建CReflectWnd类消息传递空间继承 public CWindowImpl 创建CToolbarWnd类Toolbar控件继承 public CWindowImpl 修改Toolbar的Title const WCHAR TITLE_CColimasBar[] = LGoogle; 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_EditWndGetWindowTextLength()) { WCHAR *bstr = NULL; m_EditWndGetWindowText(&bstr); UINT i= WideCharToMultiByte(CP_UTFbstrNULLNULLNULL); //双字节转换 char *strB=new char[i]; WideCharToMultiByte (CP_UTFbstrstrBiNULLNULL); //转换为ASCII UINT len=i; char* tmp=new char[len*]; tmp[]=\; for(i=;i { byte j= (unsigned char)strB[i]; sprintf(tmp,"%s%%%x",tmp,j); //转换为16进制。Tw.wINgWiT.coM } bsSite = L"-CNq="; //Google Search字符串 bsSite += tmp; bsSite += "rls=com.microsoft:en-USie=utf8oe=utf8"; SysFreeString(bstr); delete[] strB; } else bsSite = ""; // have the webrowser navigate to the site URL requested depending on user input. m_pBrowser->Navigate(bsSite, &vEmpty, &vEmpty, &vEmpty, &vEmpty); } } 本文涉及到的所有知识请参照 |
