   IPropertyPage **ppPP
);

Return value

Remarks

To use CreateHTMLPropertyPage, which is implemented in Mshtml.dll, you must dynamically load and call this function by using the LoadLibrary function and the GetProcAddress function.

Security Warning: Using LoadLibrary incorrectly can compromise the security of your application by loading the wrong DLL. Refer to the LoadLibrary documentation for information on how to correctly load DLLs with different versions of Windows.

Examples

The following example shows the basic steps to load Mshtml.dll, obtain the address of CreateHTMLPropertyPage using GetProcAddress, create a URL moniker, and call CreateHTMLPropertyPage.

    typedef HRESULT STDAPICALLTYPE CREATEHTMLPROPERTYPAGEFN (IMoniker *pmk, IPropertyPage **ppPP);

    HINSTANCE hinstMSHTML = LoadLibrary(TEXT("MSHTML.DLL"));

    if (hinstMSHTML == NULL)
    {
        //Error loading module -- fail as securely as possible
        return;
    }   
        
    CREATEHTMLPROPERTYPAGEFN* pfnCreateHTMLPropertyPage;
    pfnCreateHTMLPropertyPage = 
        (CREATEHTMLPROPERTYPAGEFN*)GetProcAddress( hinstMSHTML,
                                TEXT("CreateHTMLPropertyPage"));
    if (pfnCreateHTMLPropertyPage)
    {
        IMoniker *pURLMoniker;
        BSTR bstrURL = 
           SysAllocString(L"http://www.example.com/dialogsource.htm");
        CreateURLMoniker(NULL, bstrURL, &pURLMoniker);

        if (pURLMoniker)
        {
            IPropertyPage *pPropertyPage;
            (*pfnCreateHTMLPropertyPage)(pURLMoniker, &pPropertyPage);
    
            pURLMoniker->Release();
        }

        SysFreeString(bstrURL);
    }

    FreeLibrary(hinstMSHTML);
