COM Signature
From oleipc.idl:
HRESULT IOleComponentUIManager::ShowHelp(
[in] DWORD dwCompRole,
[in] REFCLSID rclsidComp,
[in] POINT posMouse,
[in] DWORD dwHelpCmd,
[in] LPOLESTR pszHelpFile,

ShowHelp calls the legacy SVsHelpService service. VSPackages can access a newer service for help by calling QueryService and requesting SID_SVsHelp and IID_Help.
