Answer 1

Hi you can make it hidden at start in
OnInitDialog()
DWORD dwStyle = GetWindowLong(GetSafeHwnd(), GWL_STYLE);
dwStyle -= WS_VISIBLE;
SetWindowLong(GetSafeHwnd(), GWL_STYLE, dwStyle);
and then in OnNavigateComplete make it visible.
But if your page will load slow it will seems like your app hangup

//CYourDialog.cpp
void CYourDialog::OnWindowPosChanging(WINDOWPOS* lpwndpos)
{
//allow to hide dialog at the startup of dialog,
//delay the show of dialog until m_bVisible is set
if(!m_bVisible)
{
lpwndpos->flags &= ~SWP_SHOWWINDOW;
}
CDialog::OnWindowPosChanging(lpwndpos);
}
//CYourHtmlView.cpp
void CYourHtmlView::OnDocumentComplete()
{
m_pYourDlg->m_bVisible=TRUE;
m_pYourDlg->ShowWindow(SW_SHOW);
}

BOOL CYourDialog::OnInitDialog()
{
DWORD dwStyle = GetWindowLong(GetSafeHwnd(), GWL_STYLE);
dwStyle -= WS_VISIBLE;
SetWindowLong(GetSafeHwnd(), GWL_STYLE, dwStyle);
Invalidate();
CDHtmlDialog::OnInitDialog();
...
Navigate(_T("www.google.com"));
return TRUE; // return TRUE unless you set the focus to a control
}
void CYourDialog::OnNavigateComplete(LPDISPATCH pDisp, LPCTSTR szUrl)
{
DWORD dwStyle = GetWindowLong(GetSafeHwnd(), GWL_STYLE);
dwStyle += WS_VISIBLE;
SetWindowLong(GetSafeHwnd(), GWL_STYLE, dwStyle);
Invalidate();
}
