When an end-user clicks a link/button to connect to a URL, the security dialog automatically appears giving them the options of "Allow," "Block" or "Cancel". Should they select "Block" or "Cancel," can we trigger a message box informing them they blocked or cancelled the connection?
With traditional message boxes, we're causing them, ie
var rtnFromBox = xfa.host.messageBox("Information is missing.\n\n Are you sure you want to continue?", "Missing Information",1,2);
