Hi,

I'm a new developer on ActiveX technology. I made a component inherit from ActiveForm (in C++ Builder4) to test this technology. If I import the control in C++ Builder it work fine, but if I import the control in a HTML page, I can't read or write any property.

The sentence that I still using is:

<p><object classid="clsid:CFCDAA03-8BE4-11CF-B84B-0020AFBBCCFA"
border="0" width="274" height="223"><param name="Visible"
value="0"></object></p>

Some body knows what is wrong?

Thanks in advance, Lucio

Alex,

  You need to add support for the IPersistPropertyBag.
  Here is a small sample

  file://---------------------------------------------------------------------------
  class ATL_NO_VTABLE TActiveEFXImpl:
     VCLCONTROL_IMPL( TActiveEFXImpl, ActiveEFX, TActiveEFX, IActiveEFX,
     DIID_IActiveEFXEvents ),
     public IPersistPropertyBagImpl<TActiveEFXImpl>
            ^^^^^^^^^^^^^^^^ notice this

  ...

     AnsiString FileName; // this is data to hold the FileName property

    COM_INTERFACE_ENTRY_IMPL( IPersistPropertyBag )
     ^^^^^^^^^ add this to the BEGIN_COM_MAP

    PROP_ENTRY( "FileName", 15, CLSID_ActiveEFX)
    ^^^^^^^^^^^^^ add this to the BEGIN_PROPERTY_MAP

    STDMETHOD(get_FileName(BSTR* Value));
    STDMETHOD(set_FileName(BSTR Value));
    ^^^ add these to the methods implemented in your app ( this is
  actually done by the type library editor when you add a property.
