c# - How to obtain the Document Interface when Hosting the WebBrowser Control? -
please have @ following excellent article available on msdn
i in process of creating ie toolbar of bandobjects
i have access webbrowser control not able instantiate htmldocument require modify dom.
here excerpt of code:
// registering documentcomplete envent explorer.documentcomplete += new shdocvw.dwebbrowserevents2_documentcompleteeventhandler(explorer_documentcomplete); // not sure following function. // trying suggested in msdn article - // http://msdn.microsoft.com/en-us/library/aa752047%28v=vs.85%29.aspx#document void explorer_documentcomplete(object pdisp, ref object url) { ipersiststream pstream; string htmltext = "<html><h1>stream test</h1><p>this html content being loaded stream.</html>"; htmldocumentclass document = (htmldocumentclass)this.explorer.iwebbrowser_document; document.clear(); document.write(htmltext); ihtmldocument2 document2 = (ihtmldocument2)pdisp; pstream = (ipersiststream)document2.querycommandvalue("iid_ihtmldocument2"); htmldocument objdec = webbroswer.document; objdec.write(htmltext); }
you got bit lost in native ie object model. indeed makes bit painful load own html browser.
that's not problem if use webbrowser control. glue hidden in .net wrapper. super-simple, assign documenttext property. property setter takes care of hoopla. don't need documentcompleted event handler, collapses single line of code can put anywhere:
webbrowser1.documenttext = "<h1>hello world</h1>";
