HOWTO: Getting IHlinkFrame from Within a Hyperlink Target

 Last reviewed: January 19, 1998

The information in this article applies to:
  • Microsoft ActiveX SDK, version 1.0
  • Internet Client SDK, versions 4.0, 4.01
  • Microsoft Internet Explorer (Programming), versions 3.0, 3.01, 3.02, 4.0, 4.01

SUMMARY

In an example in the Hyperlinking section of the documentation, the Internet Client SDK indicates that an Active Document application can retrieve the IHlinkFrame interface from its container by calling QueryInterface on the container's IOleInPlaceFrame object and asking for IID_IHlinkFrame.

For Internet Explorer (IE), this will fail. The correct way to retrieve IHlinkFrame is through the IServiceProvider interface.

MORE INFORMATION

Here is sample code that demonstrates the correct method for retrieving Internet Explorer's IHlinkFrame interface: 

   IHlinkFramePtr pHLFrame;
   IOleClientSitePtr pCS = m_lpClientSite;
   IServiceProviderPtr pSP = pCS;
   pSP->QueryService(SID_SHlinkFrame, IID_IHlinkFrame,
      (void**)&pHLFrame);
In an MFC Active Document server, the IOleClientSite interface can be retrieved from within the document class using the m_lpClientSite protected member of COleServerDoc.
