ow I'm trying to make IE Security prompt dialog diaplayed. I followed this MSDN article: http://msdn.microsoft.com/library/default.asp?url=/workshop/security/szone/overview/overview.asp I set IE Security setting for "Submit nonencrypted form data" to be Prompt then set pPolicy to be URLPOLICY_QUERY in process of action URLACTION_HTML_SUBMIT_FORMS/URLACTION_HTML_SUBMIT_FORMS_FROM/URLACTION_HTML_SUBMIT_FORMS_TO in method IInternetSecurityManage::ProcessUrlAction. As my expectation, this will make prompt dialog "When you send information to the Internet, it might be possible for others to see that information. Do you want to continue?" displayed. But the prompt dialog didn't show up. If I set pPolicy to be URLPOLICY_ALLOW and URLPOLICY_DISALLOW, both works well. My IE version is 6.0.2800.1106.xpsp2.050301-1526. I'd like to know how to make this prompt dialog popup? Thank you!
