you can get a demo of the library at the following link:

I'm not doing ad or marketing, but this is one of the best MFC library with Stingray Studio.

Hi,

you can find what you seek with the "BCGPOutlookDemo.exe" which is a demo that shows an outlook 2003 interface and "BCGPIEDemo.exe" in the "Time controls" panel.

Best regards.

Isn't CDateMonthPicker or something exactly what you want? It's one of the common controls. Anything more complicated can't be free...

I've created a pipe. I wish to read from the pipe only when data is available. What should I use. Can I use an Overlap Structure? Or, maybe a ComWaitEvent? What is generally done when reading pipes. I don't want to create a thread which constantly reads a pipe regradless of the data available. Thanks.

Yes, you can use overlapped IO, or overlapped IO completion ports, or loop on a sync read in a separate thread that will block while there is no data.

Regardless of the method, you are likely going to want to create thread(s) to read from the pipe if you don't want your main thread to block.

The most robust solution is to use IOCP. IOCP can be used to service overlapped requests for any handle returned by CreateFile or WSASocket/socket.

Thanks very much.

Handle WM_NCPAINT to change appearance. Then perform hittest to determine what elements of new title bar are clicked and ensure they respond the way you need them to.

A site for mshtml interface

Can anybody tell me a site that explains mshtml interface(IHtmlTxtRange,IHtmlBodyElement). THanx

First step should always be MSDN

IHtmlTxtRange

IHtmlBodyElement

If you need help in using these from within C++ I'd be happy to help

Hope this helps,
Andy

Thank you Andy, Iam virtually new to vc++ . I got a DHTMLED sample from msdn and wanted to set background sound using IHTMLBGsound and i tried but could't get it.

Hi,

Are the HTML pages yours (or public sites)?

If they are yours then the easiest thing to do is the following:

In your pages include the <bgsound> tag (with the src attr empty) and an ID, e.g.

<html>
...
<bgsound src='' id='idSound1'>
...
</html>

Then in your OnDocumentComplete event in VC++ you can run the following code:

MSHTML::IHTMLDocument2Ptr spDoc(m_ctlWeb1.GetDocument());
if (spDoc)
{
    // Find the BGSOUND tag...
    MSHTML::IHTMLDocument3Ptr spDoc3 = spDoc;
    if (spDoc3)
    {
        // you could also use getElementByTagName but for simplicity...
        MSHTML::IHTMLElementPtr spElem2 = spDoc3->getElementById(_bstr_t("idSound1"));
        if (spElem2)
        {
            MSHTML::IHTMLBGsoundPtr spBG = spElem2;
            if (spBG)
            {
                CString strURL = _T("http://server/eg/alert.wav");
                spBG->put_src(_bstr_t(strURL));
            }
        }
    }
}

If they are public sites and you are trying to inject a <bgsound> into them - this will be a little bit more work...

Firstly, we need to get DOM to create us an <bgsound> element, and then insert it into the document. As before, we do this in the OnDocumentComplete event...

MSHTML::IHTMLElementPtr spElem = spDoc->createElement(_T("BGSOUND"));
if (spElem)
{
    MSHTML::IHTMLBGsoundPtr spBG = spElem;
    if (spBG)
    {
        CString strURL = _T("http://server/eg/alert.wav");
        spBG->put_src((bstr_t)strURL);

        // get the DOMNode interface for the BODY...
        MSHTML::IHTMLDOMNodePtr spBody = spDoc->body;
        // get the DOMNode interface for the element we wish to add...
        MSHTML::IHTMLDOMNodePtr spNode2Add = spBG;

        if (spBody != NULL && spNode2Add != NULL)
        {
            // append new element to BODY
            spBody->appendChild(spNode2Add);
        }
    }
}

And that's it Smile | :)

Hope this helps,
Andy

Thank you Andy,but My view is not derived from CHTMLView my view is derived from CView,IOleInPlaceFrame and IOleCommandTarget and iam using my own html pages.I think IHTMLBGsound is not supported in it ( I tried to paste it using pasteHTML).

Hi again,

Neither was my test app. I created a test app and inserted the WebBrowser ActiveX Control into the dialog. Then used the Event sinking (through class wizard) to handle the DocumentComplete event, e.g.

BEGIN_EVENTSINK_MAP(CWebTest1Dlg, CDialog)
    //{{AFX_EVENTSINK_MAP(CWebTest1Dlg)
	ON_EVENT(CWebTest1Dlg, IDC_EXPLORER1, 259 /* DocumentComplete */, OnDocumentCompleteExplorer1, VTS_DISPATCH VTS_PVARIANT)
	//}}AFX_EVENTSINK_MAP
END_EVENTSINK_MAP()

The BGSOUND element was available from IE3, and available in script from IE4 so I can't see that it's not supported. How are you using the Web Control in your app?

Cheers,
Andy

I got a DHTMLED sample from msdn (just enter DHTMLED in search).Run the exe and You will find a folder sample/Edit/. I want IhtmlBGsound implemented in it. Thank you for following it up.

Hi lokesh,

I've had no luck finding this sample project. Do you have a link to it?

I tried online MSDN as well as the MSDN Library Disks (Jan 2003)

or just type "DHTMLED" in google and click the first one.

Hi lokesh,

Right I found the project you are on about. Just to clarify - it was the CEdit project was it not?

Anyway I've had a look and have got it to insert the BGSOUND element.

This project must have been written way way back and is a very verbose way of doing things. Anyway I digress.

This is what I did:

Firstly, we what to inject the element on the Document Complete event but because this is an old application we have to do it the old way. Events from the HTMLDOMDocument are handled by the CImpIDispatch class in DOCEVENT.cpp, we can tell this because in the crtview.cpp you see the following line:

hr = m_pConnectionPoint->Advise( m_pDocEvents, &m_dwConnectCookie );

So we are setting the object for the DOMDocument to call us back on.

Then in the CImpIDispatch class, we need to look for the ::Invoke method, this is what will get called whenever any events take place - dispIdMember parameter will hold what event it actually is (see MSDN for all the events)

The event we are interested in is: DISPID_HTMLDOCUMENTEVENTS_ONREADYSTATECHANGE

readyState is a property of the document that tells you what the state of it is - we want to wait for it to be "complete"

So here is the code I used in the ::Invoke method:

USES_CONVERSION;

if ( dispIdMember == DISPID_HTMLDOCUMENTEVENTS_ONREADYSTATECHANGE )
{
    MSHTML::IHTMLDocument2Ptr spDoc(m_pView->m_pSite->GetObjectUnknown());
    if (spDoc)
    {
        CString strState = OLE2T(spDoc->readyState);
        if (strState == _T("complete"))
        {
            MSHTML::IHTMLElementPtr spElem = spDoc->createElement(_T("BGSOUND"));
            if (spElem)
            {
                MSHTML::IHTMLBGsoundPtr spBG = spElem;
                if (spBG)
                {
                    CString strURL = _T("http://www.htmlcodetutorial.com/sounds/hazy_shade_of_winter.mid");
                    spBG->put_src(T2OLE(strURL));

                    // get the BODY element
                    MSHTML::IHTMLDOMNodePtr spBody = spDoc->body;
                    // and the IHTMLDOMNode interface of the new element
                    MSHTML::IHTMLDOMNodePtr spNode2Add = spBG;
                    // append new element to BODY
                    spBody->appendChild(spNode2Add);
                }

            }
        }
    }
}

Now you may notice that above I'm using the smart pointer implementation for COM calling - I did start doing in the traditional way but I got so bored with doing QueryInterface all the time. So add the following to the top of the cpp file:

#import "C:\Windows\system32\mshtml.tlb" no_auto_exclude

Actually there is another reason - the mshtml.h file that is already included in the file points to a version in your VC install directory - and this is woefully out of date (i.e. doesn't include the IHTMLDOMNode interface that we require)

Ok, no also don't forget to include:

#include <AFXPRIV.H>

In your stdafx.h as we are using the USES_CONVERSION macro to help us with string conversion.

I'm going to end it now, rather than babble on and on. I hope I've got the right end of the stick of what you wanted to achieve ?? Any questions just ask

Andy
