Hello,

I have folling code inside one of my projects:

IHTMLElement       *pElement = (IHTMLElement *) NULL;
IHTMLElementRender *pRender = (IHTMLElementRender *) NULL; // <-- causes
linker error


After compilation I got an linker error:

[Linker Error] Unresolved external '_IID_IHTMLElementRender' referenced from
D:\TTEST\UNIT1.OBJ

I found out, that IHTMLElement is declared in mshtml.h which I included, but
IHTMLElementRender is not!

If I look into the mshtml.h which comes with C++ BuilderX the
IHTMLElementRender is declared inside, but I do need the implementation of
the IHTMLElementRender also such as mshtml.lib, or mshtml.pas or something
like that. How can I make now my CppBuilder6 access the IHTMLElementRender
interface???

Is there an update available? Or can I extract from a DLL?

Thanks for any help!

IID_IHTMLElementRender doesn't even exist in BCB6 at all.  It is not even
declared in any of the header files.  Did you add it to your code manually?

You will have to add it to your code manually:

    --- IHTMLElementRender.h ---

    #include <mshtml.h>

    #ifndef __IHTMLElementRender_FWD_DEFINED__
    #define __IHTMLElementRender_FWD_DEFINED__
    typedef interface IHTMLElementRender IHTMLElementRender;
    #endif  /* __IHTMLElementRender_FWD_DEFINED__ */

    #ifndef __IHTMLElementRender_INTERFACE_DEFINED__
    #define __IHTMLElementRender_INTERFACE_DEFINED__

    /* interface IHTMLElementRender */
    /* [uuid][unique][object] */

    EXTERN_C const IID IID_IHTMLElementRender;

    MIDL_INTERFACE("3050f669-98b5-11cf-bb82-00aa00bdce0b")
    IHTMLElementRender : public IUnknown
    {
    public:
        virtual HRESULT STDMETHODCALLTYPE DrawToDC(
            /* [in] */ HDC hDC) = 0;

        virtual HRESULT STDMETHODCALLTYPE SetDocumentPrinter(
            /* [in] */ BSTR bstrPrinterName,
            /* [in] */ HDC hDC) = 0;
    };

    #endif  /* __IHTMLElementRender_INTERFACE_DEFINED__ */


    --- IHTMLElementRender.cpp ---

    #include "IHTMLElementRender.h"

    const IID IID_IHTMLElementRender = {0x3050F669, 0x98B5, 0x11Cf, {0xBB,
0x82, 0x00, 0xAA, 0x00, 0xBD, 0xCE, 0x0B}};


Add IHTMLElementRender.cpp to your project, and then include
IHTMLElementRender.h into your code where needed.

No, and no.
