how to add hyperlink in word2003 automation using VC++?

I am using visual studio 2008 and world 2003. In my MFC DLL project, i need to use word 2003 automation api to create a new word document. But i want to know how to add a hyperlink to a text?

int CDOCXRun::InstantiateInOLE(COLERange &OLERange, CDOCXContext& Context)
{
    int lastEnd = OLERange.get_End();
    // Firstly we insert contents by iterating through all child elements and check their name.
    for (CXMLElement *ElementIterator = m_lpElement->FirstChildElement(); ElementIterator != NULL; ElementIterator = ElementIterator->NextSiblingElement())
    {
        DOCX_IGNORE_EXCEPTIONS_BEGIN
        CString strName = ElementIterator->GetName(); // Get the name of the current child element

        // if the name equales to <w:t>, this run is a small piece of text and its text is stored just in thr following format: 
        // <w:t> Text </w:t>
        if (strName == DOCX_XML_TAG_TEXT) 
        {
            CString lpText = ElementIterator->GetValue(); // Get text string from xml
            if (lpText.IsEmpty())
                lpText = _T(" ");
            else
                nTextCount ++;

            CString strText = lpText; // OLE uses unicode for inserting data, conver the multibyte string into CString using UTF-8 codeset
            OLERange.put_Text(strText); // Set text in rang

        }

        // If the name equals to <w:tab>, just insert a tab charactor
        if (strName == DOCX_XML_TAG_TAB) 
        {
            OLERange.put_Text(_T("\t"));
        }

        // If the name equals to <w:drawing>, it may be a picture.
        // Although picture is only the special case of drawing, we consider only the circumstances of pictures.
        if (strName == DOCX_XML_TAG_DRAWING)
        {
            CDOCXPicture Picture(ElementIterator); // Create a CDOCXPicture object on the child element.
            // Check whether the picture is valid
            if (Picture.IsValid())
            {
                Picture.InstantiateInOLE(OLERange,Context); // Call the InstantiateInOLE method to insert this picture into word
                nPicCount ++;
            }

        }
        DOCX_IGNORE_EXCEPTIONS_END
    }

    // Apply run property
    DOCX_IGNORE_EXCEPTIONS_BEGIN
    CXMLElement *rPr = m_lpElement->FirstDescendantElement(DOCX_XML_TAG_RUN_PROPERTY); // Get the xml node with <w:rPr> name, which stores formats of this run
    if (rPr != NULL)
    {
        CDOCXRunProperty RunProperty(rPr); // Create an CDOCXRunProperty object on the <w:rPr> xml element.
        RunProperty.InstantiateInOLE(OLERange, Context); // Call the InstantiateInOLE method to apply the formats specified in <w:rPr> elements into current run
    }
    DOCX_IGNORE_EXCEPTIONS_END

    int nowEnd = OLERange.get_End();
    return nowEnd;
}

we know that word is actually composed of xml files and a hyperlink is represented like this"

<w:hyperlink r:id="rId9" w:history="1">
<w:r w:rsidR="00BF5AA1" w:rsidRPr="00A16638">
<w:rPr>
<w:rStyle w:val="Hyperlink"/>
<w:rFonts w:hint="eastAsia"/>
</w:rPr>
<w:t>检查文件</w:t>
</w:r>
<w:r w:rsidR="00FE551D" w:rsidRPr="00A16638">
<w:rPr>
<w:rStyle w:val="Hyperlink"/>
<w:rFonts w:hint="eastAsia"/>
</w:rPr>
<w:t>是否包含文件头注释</w:t>
</w:r>
<w:r w:rsidR="00BF5AA1" w:rsidRPr="00A16638">
<w:rPr>
<w:rStyle w:val="Hyperlink"/>
<w:rFonts w:hint="eastAsia"/>
</w:rPr>
<w:t>。</w:t>
</w:r>
</w:hyperlink>

my problem is that i can use OLERange.put_Text(strText); to generate text such as http://www.google.com, but i don't know how to make a hyperlink. when you push CTRL and click, it will open your web browser and jump into google.com from word document.
