如何在加载页面之前隐藏CDHTMLDialog？

Question

调用DoModal方法后，对话框将立即显示。但是我需要在页面加载之前使它不可见。那可能吗？

Answer 1

嗨，你可以把它隐藏在开局

OnInitDialog() 
    DWORD dwStyle = GetWindowLong(GetSafeHwnd(), GWL_STYLE); 
    dwStyle -= WS_VISIBLE; 
    SetWindowLong(GetSafeHwnd(), GWL_STYLE, dwStyle); 

，然后在OnNavigateComplete使其可见。 但是，如果页面加载缓慢它会看起来像你的应用挂断

//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(); 
}
