以上为控件实现代码；

IID_AudioOleCtrl为控件GUID，可以自己生成。

接口说明：

InitOleWindow：初始化Ole窗口

GetAudioState：获取Audio状态

GetAudioPath：获取Audio文件路径

GetAudioDuration：获取Audio文件播放时长

GetAudioId：获取元素ID

AudioPlayFinish：Audio播放完成时调用

OnAudioPlayClick：静态状态点击事件

OnAudioPlayingClick：播放状态点击事件

以下是控件布局相关XML：

<root><window pos="0,0,-0,-0" skin="skin.empty"><image name="play" cursor="hand" pos="0,0"/><image name="playing" cursor="hand" pos="0,0" /><text name="audio_duration" pos="[5,22" align="center" colorText="#000000" dotted="1" font="size:12"/><image name="isplayed" pos="110,15" skin="skin.richaudio_reddot" show="1" /></window>
</root>

控件需要在uires.idx文件中添加相关映射关系

注意：

在使用时还需要在以下文件的接口中添加相关代码：

RichEditObjFactory.cpp文件的RichEditObjFactory接口中添加_creaters[RichEditAudioOle::GetClassName()] = RichEditAudioOle::CreateObject;

如下所示：

    RichEditObjFactory::RichEditObjFactory(){_creaters[RichEditText::GetClassName()] = RichEditText::CreateObject;_creaters[RichEditBkElement::GetClassName()] = RichEditBkElement::CreateObject;_creaters[RichEditPara::GetClassName()] = RichEditPara::CreateObject;_creaters[RichEditContent::GetClassName()] = RichEditContent::CreateObject;_creaters[RichEditFetchMoreOle::GetClassName()] = RichEditFetchMoreOle::CreateObject;_creaters[RichEditImageOle::GetClassName()] = RichEditImageOle::CreateObject;_creaters[RichEditFileOle::GetClassName()] = RichEditFileOle::CreateObject;_creaters[RichEditSeparatorBar::GetClassName()] = RichEditSeparatorBar::CreateObject;_creaters[RichEditMetaFileOle::GetClassName()] = RichEditMetaFileOle::CreateObject;_creaters[RichEditReminderOle::GetClassName()] = RichEditReminderOle::CreateObject;_creaters[RichEditAudioOle::GetClassName()] = RichEditAudioOle::CreateObject;}

RichEditOleCallback.cpp文件的QueryInsertObject接口中添加相关代码，如下所示：

    HRESULT RichEditOleCallback::QueryInsertObject(LPCLSID lpclsid,LPSTORAGE lpstg,LONG cp){if (lpclsid == NULL){return E_INVALIDARG;}if (*lpclsid == IID_ImageOleCtrl ||*lpclsid == IID_FileOleCtrl ||*lpclsid == IID_FetchMoreOleCtrl ||*lpclsid == IID_SeparatorBarCtrl ||*lpclsid == IID_RichMetaFileOle ||*lpclsid == IID_RemainderOleCtrl ||*lpclsid == IID_AudioOleCtrl){return S_OK;}return E_FAIL;}

以上为OLE控件相关代码；

下边我们看看新控件的使用：

SStringW strAudio;
std::string strAudioId = KfUtility::GenerateUUID();
std::wstring wstrAudioId;
KfUtility::ConvertUtf8ToUtf16(strAudioId, wstrAudioId);
strAudio.Format(L"<audio id=\"%s\" audio_duration=\"12\" audio_path=\"D:\\imrepose\\trunk\\KFClient6\\output\\Debug_Unicode\\default_res\\test.amr\"/>", wstrAudioId.c_str());
SStringW strContent;
strContent.Format(L"<RichEditContent  type=\"ContentLeft\" align=\"left\">"L"<para>"L"</para>"L"<bkele data=\"avatar\" id=\"%s\" skin=\"%s\" pos=\"0,]-2,@40,@40\" cursor=\"hand\" interactive=\"1\"/>"L"<para id=\"msgbody\" margin=\"50,0,0,0\" break=\"1\" simulate-align=\"1\">"      L"%s"L"</para>"L"%s"L"</RichEditContent>",wstrId.c_str(), wstrFaceId.c_str(), strAudio, pEmpty);
pRecvRichEdit->InsertContent(strContent, RECONTENT_LAST);
