How to disable all possible popup messages in CDHtmlDialog?

I use CDHtmlDialog to work with DOM of some HTML content from given URLs. I need to disable all possible popup messages (e.g Security alerts) that can appear as in case of InternetExplorer Browser. In JScript I can set property Silen开发者_JAVA技巧t to true

var oIE = WScript.CreateObject("InternetExplorer.Application","EventIE_");
oIE.Silent = true;

and that's work! How to get same behaviour in CDHtmlDialog?

Thanks

I found the solution!

m_pBrowserApp->put_Silent(VARIANT_TRUE);
