PRB: Events Not Firing When IE4 WebBrowser Placed On Web Page

MORE INFORMATION

You cannot write Script event handlers for WebBrowser control events, such as DocumentComplete, BeforeNavigate2, and other events, when you host the WebBrowser control in an HTML page by using the OBJECT tag. These events are not fired. These events are not fired even if the WebBrowser control is wrapped in another ActiveX control and then embedded in HTML.

If the reason for hosting the WebBrowser control in an HTML page is to display documents within your Web page, Microsoft recommends that you use the IFRAME tag.

Steps to Reproduce the Behavior

1. Type and then save the following HTML as C:\Page1.htm:

   <HTML>
   <HEAD>
      <TITLE>WebBrowser Control in HTML</TITLE>
   </HEAD>
   <BODY>
   
   <SCRIPT LANGUAGE="VBScript">
   Sub WebBrowser1_BeforeNavigate2(pDisp, URL, Flags, _
         TargetFrameName,  PostData, Headers, Cancel)
      MsgBox "BeforeNavigate2"
   end sub
   
   Sub WebBrowser1_DocumentComplete(pDisp, URL)
      MsgBox "DocumentComplete"
   end sub
   
   Sub Window_OnLoad()
      WebBrowser1.Navigate "http://www.microsoft.com"
   End Sub
   </SCRIPT>
   					

2. Navigate to C:\Page1.htm from Internet Explorer 4.0.

DocumentComplete and BeforeNavigate2 events are not fired.
