执行步骤的示例
创建名为 OffCntrDisp 的新 MFC ActiveX 控件向导应用程序。
COleControl 派生类中添加下面的成员变量:
char m_szDocName[512];
IDispatch *m_pDocDisp;
注: m_szDocName 保存包含我们的控制的文档的名称并且 m_pDocDisp 是该文档的 IDispatch 接口。
COleControl 派生类定义中的末尾添加以下项:
// Interface Maps.
protected:
// IoleObject.
BEGIN_INTERFACE_PART(MyOleObject, IOleObject)
INIT_INTERFACE_PART(COffCtlDispCtrl, MyOleObject)
STDMETHOD(SetClientSite)(LPOLECLIENTSITE);
STDMETHOD(GetClientSite)(LPOLECLIENTSITE*);
STDMETHOD(SetHostNames)(LPCOLESTR, LPCOLESTR);
STDMETHOD(Close)(DWORD);
STDMETHOD(SetMoniker)(DWORD, LPMONIKER);
STDMETHOD(GetMoniker)(DWORD, DWORD, LPMONIKER*);
STDMETHOD(InitFromData)(LPDATAOBJECT, BOOL, DWORD);
STDMETHOD(GetClipboardData)(DWORD, LPDATAOBJECT*);
STDMETHOD(DoVerb)(LONG, LPMSG, LPOLECLIENTSITE, LONG, HWND,
LPCRECT);
STDMETHOD(EnumVerbs)(IEnumOLEVERB**);
STDMETHOD(Update)();
STDMETHOD(IsUpToDate)();
STDMETHOD(GetUserClassID)(CLSID*);
STDMETHOD(GetUserType)(DWORD, LPOLESTR*);
STDMETHOD(SetExtent)(DWORD, LPSIZEL);
STDMETHOD(GetExtent)(DWORD, LPSIZEL);
STDMETHOD(Advise)(LPADVISESINK, LPDWORD);
STDMETHOD(Unadvise)(DWORD);
STDMETHOD(EnumAdvise)(LPENUMSTATDATA*);
STDMETHOD(GetMiscStatus)(DWORD, LPDWORD);
STDMETHOD(SetColorScheme)(LPLOGPALETTE);
END_INTERFACE_PART(MyOleObject)
DECLARE_INTERFACE_MAP();
这将重写您的自定义 MyOleObject 与 IOleObject COleControl 的默认实现。
COleControl 派生类的构造函数中添加以下代码:
m_pDocDisp = NULL;
紧随其后 OffCntrDispCtl.cpp 中的以下行:
IMPLEMENT_OLECTLTYPE(COffCntrDispCtrl, IDS_OFFCNTRDISP,
_dwOffCntrDispOleMisc)
添加以下代码:
BEGIN_INTERFACE_MAP(COffCntrDispCtrl, COleControl)
INTERFACE_PART(COffCntrDispCtrl, IID_IOleObject, MyOleObject)
END_INTERFACE_MAP()
此操作,请在步骤 3 中所做的修改以及覆盖 COleControl 的 IOleObject。
第 5 步中添加的代码,下面添加以下代码:
static char buf[8192];
static void DoMsg(char *msg) {
::MessageBox(NULL, msg, "Message", MB_SETFOREGROUND);
}
static void DoErr(char *msg, long err) {
static char errBuf[8192];
sprintf(errBuf, "%s, Error: %ld (%08lx)", msg, err,err);
::MessageBox(NULL, errBuf, "Error", MB_SETFOREGROUND);
}
这些都是以后用于显示邮件的有用例程。
将粘贴的所有以下代码在您的 OffCntrDispCtl.cpp 文件的末尾:
STDMETHODIMP COffCntrDispCtrl::XMyOleObject::SetHostNames(LPCOLESTR
pwApp, LPCOLESTR pwObj)
{
METHOD_MANAGE_STATE(COffCntrDispCtrl, MyOleObject)
ASSERT_VALID(pThis);
// Convert OLESTR into ASCII string.
WideCharToMultiByte(CP_ACP, 0, pwObj, -1, pThis->m_szDocName,
512, NULL, NULL);
// Get IDispatch.
pThis->GetDocDispatch();
// Test it out by getting the document name.
pThis->TestDispatch();
return S_OK;

这是您的 IOleObject,通常将委托其调用默认 COleControl 的 IOleObject 实现,除 SetHostNames() 之外的所有实现。补漏白,SetHostNames(),并存储该文档的名称插入控件的位置。
遗憾的是,Microsoft PowerPoint 不能调用此方法,因此,此示例将不会使用该产品。但是,Microsoft Powerpoint 是单个服务器,因此您可以使用 GetActiveObject() 来唯一获得 IDispatch 指针。
