Hello,

You may find information here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/htmlhelp/html/vsconHowcallingthehtmlhelpapi.asp


You can get the htmlhelp.h file from OWLNext site:
http://owlnext.sourceforge.net/add_ons/add_fil.zip
It works with Borland C++ 5, try to see if it works
with 4.5 ... if not, then probably you will not be abel to use HTMLHelp


Afterwards you can load htmlhelp.ocx dynamicaly and call it's methods, 
like this:

typedef HWND WINAPI (*HtmlHelpFunc)( HWND hwndCaller, LPCSTR pszFile,
UINT uCommand, DWORD dwData );

const char pszHelpOCXCtrl [] = "hhctrl.ocx";

hHelpOCX = ::LoadLibrary(pszHelpOCXCtrl);
if (!hHelpOCX) {
    ::MessageBox(hwndCaller, "Cannot use the html help!", "Error", MB_OK);
   return;
}

HTMLHelp = (HtmlHelpFunc)::GetProcAddress(hHelpOCX, ATOM_HTMLHELP_API_ANSI);

// Now call HTMLHelp functions:

HTMLHelp(hWnd, "myhelp.chm", HH_DISPLAY_TOPIC, 0);
HTMLHelp(hWnd, "myhelp.chm", HH_HELP_CONTEXT, id);
