htmlviewer.zip from FAQ

Hello. There are very interesting example in the FAQ, htmlviewer.zip (29.1 question), especially in part of using shdocvw without wrapper. It works fine, but I need an ExecWB sub in interface IWebBrowser2. If I declare it, for example: void ExecWB(int cmdID, int cmdexecopt, [System.Runtime.InteropServices.Optional()] ref object pvaIn, [System.Runtime.InteropServices.Optional()] ref object pvaOut); program isn't working without errors - drawns only a white rectangle in place of webbrowser. Please help, where is my mistake? Thanks, Dmitry
