Etc..

//--------------------------------------------------------------------------
----
void __fastcall TMainForm::get_I (IHTMLDocument2 *HTMLDoc)
{
    Mshtml_tlb::IHTMLWindow2 *HTMLWindow = NULL;
    HTMLDoc->get_parentWindow(&HTMLWindow);

    IOleObject         *pOleObject      = NULL;
    IOleClientSite     *pOleClientSite  = NULL;
    IOleDocumentSite   *pOleDocumentSite= NULL;

    IDocHostUIHandler  *pHostUIHandler  = NULL;
    IDocHostShowUI     *pHostShowUI     = NULL;
    ICustomDoc         *pCustomDoc      = NULL;

    //HTMLWindow->navigate((WideString)"http://www.yahoo.co.kr"); <-- it
works good.
    //HTMLWindow->alert((WideString)"test message"); <-- it works good.

    if ( SUCCEEDED( HTMLWindow->QueryInterface(IID_IOleObject,
(LPVOID*)&pOleObject )) )
    {
        ShowMessage("OK-0"); // <-- not visible
    }

    if ( SUCCEEDED( HTMLWindow->QueryInterface(IID_IOleDocumentSite,
(LPVOID*)&pOleDocumentSite )) )
    {
        ShowMessage("OK-a"); // <-- not visible

    }

    if ( SUCCEEDED( HTMLWindow->QueryInterface(IID_IOleClientSite,
(LPVOID*)&pOleClientSite )) )
    {
        ShowMessage("OK-1"); // <-- not visible

    }

    if ( SUCCEEDED( HTMLWindow->QueryInterface(IID_IDocHostUIHandler,
(LPVOID*)&pHostUIHandler )) )
    {
        ShowMessage("OK-2"); // <-- not visible

    }

    if ( SUCCEEDED( HTMLWindow->QueryInterface(IID_IDocHostShowUI,
(LPVOID*)&pHostShowUI )) )
    {
        ShowMessage("OK-3"); // <-- not visible

    }

    if ( SUCCEEDED( HTMLWindow->QueryInterface(IID_ICustomDoc,
(LPVOID*)&pCustomDoc )) )
    {
        ShowMessage("OK-4"); // <-- not visible

    }

ShowMessage("DONE!");

How get pOleObject, pOleDocumentSite, pOleClientSite, pCustomDoc,
pHostUIHandler, pHostShowUI, pCustomDoc.. Etc ??

MSDN say < The mechanism for WebBrowser Control customization is designed to
be automated when a container provides support for ActiveX controls.
Whenever the WebBrowser Control is instantiated, it attempts to find
IDocHostUIHandler, IDocHostUIHandler2 and IDocHostShowUI implementations
from the host, if they are available. The WebBrowser Control does this by a
QueryInterface call on the host's IOleClientSite interface.>
I guss if sucess to get IOleClientSite or IOleObject then it is possible to
get IDocHostUIHandler, IDocHostUIHandler2, IDocHostShowUI...

like this


    if ( SUCCEEDED( pOleObject ->QueryInterface(IID_ICustomDoc,
(LPVOID*)&pCustomDoc )) )
    {
        // to do...
    }


Please help me..................... thanks.
