Determining URL from ActiveX Control

Introduction

I used GetMoniker method of IOleClientSite Interface.The IMoniker interface has GetDisplayName() method,
which returns a user-readable representation of the moniker.

Code:

 HRESULT hrResult	= S_FALSE;
 IOleClientSite *pClientSite = NULL;
 IMoniker* pMoniker	= NULL;
 LPOLESTR sDisplayName;

 // If using ATL to develop, use the m_spClientSite data
 // member of CComControl class.

 // If using MFC, use the following code: 
 // (member function of COleControl class 
 // - don't forget to call release)
 // pClientSite = GetClientSite();

 hrResult = m_spClientSite->GetMoniker(OLEGETMONIKER_TEMPFORUSER,
                                       OLEWHICHMK_CONTAINER,
                                       &pMoniker);
 if(SUCCEEDED(hrResult))
 {
  hrResult = pMoniker->GetDisplayName(NULL,
                                      NULL,
                                      &sDisplayName);
  pMoniker->Release();
 }

 //TODO : relevant processing with sDisplayName and
 //free sDisplayName using SysFreeString()
