CHtmlView printing in CDialog?

Hi, all:

I tried to load an html file into a CHtmlView control on CDialog and
print it out. I dynamic create the CHtmlView in the OnInitDialog
event and the CHtmlView load the htm file successfully. But I has
problems to print the html to a printer?

I tried :
pView->ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DODEFAULT, NULL, NULL); it
does nothing.

pView->OnFilePrint(); it print an empty page. (The html should print 9
pages)

I also tried:

    LPOLECOMMANDTARGET lpTarget = NULL;
    LPDISPATCH lpDisp = pView->GetHtmlDocument();

    if (lpDisp != NULL)
    {
              // the control will handle all printing UI

         if (SUCCEEDED(lpDisp->QueryInterface(IID_IOleCommandTarget,
                   (LPVOID*) &lpTarget)))
         {
              lpTarget->Exec(NULL, OLECMDID_PRINT, 0, NULL, NULL);
              lpTarget->Release();
         }
         lpDisp->Release();
    }

It print an empty page.

But if I added pView->OnFilePrint(); 2 printer dialog popup and it
will print an empty page plus the 9 pages of html.

Anyone can help me with this problem?

Following is the code

BOOL CHtmlViewDlg::OnInitDialog()
{

    CString strAppPath = AfxGetApp()->m_pszHelpFilePath;
    strAppPath = strAppPath.Left(strAppPath.ReverseFind('\\'));
    RECT rc;
    GetClientRect(&rc);
    CFrameWnd * pfrm = (CFrameWnd*) RUNTIME_CLASS(CFrameWnd)-
    
pfrm->Create(NULL, NULL, WS_CHILD | WS_VISIBLE, rc, this);
    CCreateContext pContext;
    pContext.m_pNewViewClass = RUNTIME_CLASS(CHtmlView);
    CHtmlView *pView = (CHtmlView *) pfrm->CreateView(&pContext);
    if(!pView)
    {
        //IE4 probably not installed, view couldn't be created
        //Just open the HTML document with the standard HTML viewer
        ShellExecute(m_hWnd, _T("open"), strAppPath + _T("\\print.htm"),
        NULL, NULL, SW_MAXIMIZE);
        EndDialog(IDCANCEL);//without HTML page the dialog is useless,
destroy it
        return FALSE;
    }
    pView->Navigate(strAppPath + _T("\\print.htm"));

    //pView->ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DODEFAULT, NULL, NULL);

    LPOLECOMMANDTARGET lpTarget = NULL;
    LPDISPATCH lpDisp = pView->GetHtmlDocument();

    if (lpDisp != NULL)
    {
         if (SUCCEEDED(lpDisp->QueryInterface(IID_IOleCommandTarget,
                   (LPVOID*) &lpTarget)))
         {
              lpTarget->Exec(NULL, OLECMDID_PRINT, 0, NULL, NULL);
              lpTarget->Release();
         }
         lpDisp->Release();
    }

// pView->OnFilePrint();
    return TRUE;
}
