I am lost and I do not know how to deal with that.

I tried to define a new type of help viewer (in fact tried to interface the 
HTMLHelp with C++ Builder).
I have defined a class THtmlHelpViewer to deal with the problem... Here is 
the snipet of relevant information for the class itself

HEADER:
class THtmlHelpViewer : public TInterfacedObject
{
(...)
protected:
    IHelpManager* fiHelpManager;
(...)
public:
    __property IHelpManager* iHelpManager = {read = fiHelpManager, write = 
fiHelpManager};
(...)
};

SOURCE:
(...)
void InitServices()
{
  IHtmlHelpViewer = 
dynamic_cast<ICustomHelpViewer*>((ICustomHelpViewer*)HtmlHelpViewer);
  IHtmlHelpViewer->AddRef();
  Helpintfs::RegisterViewer(IHtmlHelpViewer, ????);
  Application->HelpSystem->AssignHelpSelector((IHelpSelector*) 
HtmlHelpViewer);
}
#pragma startup InitServices
(...)

I am lost because I do not know how to pass the second parameter for 
RegisterViewer.
The online help says that the paramater is a reference to a 
_di_IHelpManager, but the developper's guide (7-32) says that the second 
parameter is an IHelpManager...

So if I try to call RegisterViewer(IHtmlHelpViewer, 
HtmlHelpViewer->iHelpManager) I have the two following errors:
 [C++ Warning] UnitHTMLHelp.cpp(19): W8030 Temporary used for parameter 
'Manager' in call to '_fastcall 
RegisterViewer(_di_ICustomHelpViewer,_di_IHelpManager &)'
 [C++ Error] systobj.h(256): E2193 Too few parameters in call to '_fastcall 
IHelpManager::Release(const int)'

If I try on the other hand to call RegisterViewer(IHTMLHelpViewer, 
*(HtmlHelpViewer->iHelpManager)) I have then the following errors
  [C++ Warning] UnitHTMLHelp.cpp(19): W8030 Temporary used for parameter 
'Manager' in call to '_fastcall 
RegisterViewer(_di_ICustomHelpViewer,_di_IHelpManager &)'
 [C++ Error] UnitHTMLHelp.cpp(19): E2064 Cannot initialize '_di_IHelpManager 
&' with 'IHelpManager'
 [C++ Error] UnitHTMLHelp.cpp(19): E2342 Type mismatch in parameter 
'Manager' (wanted '_di_IHelpManager &', got 'IHelpManager')

and if I try the following call Helpintfs::RegisterViewer(IHtmlHelpViewer, 
(_di_IHelpManager&)(HtmlHelpViewer->iHelpManager)) I have of course no error 
at the compilation, who would with a "dirty cast" like this, but the system 
just go ballistic at the execution.



Notice I do not want to have a temporary parameter for 'Manager' as I need 
to get that value...I do not know how to deal with that situation... please 
someone help me! ;)

Thanks for your comments...
