MORE INFORMATION

Steps to reproduce behavior

1. Create a new user control project in Visual Basic.
2. Add two command buttons to the default form for the control.
3. Add the following code:

         Private Sub Command1_Click()
            Parent.bgcolor = vbRed
         End Sub
   
         Private Sub Command2_Click()
            Parent.bgcolor = vbBlue
         End Sub
   
         Private Sub UserControl_AmbientChanged(PropertyName As String)
            MsgBox "ambient changed"
         End Sub
   					

4. Make the control.
5. Place the control on a Web page (make sure you replace the CLSID in the code below):

   <HTML>
   <HEAD><TITLE>Repro of DISPID_UNKNOWN AmbientChanged
   Bug</TITLE></HEAD>
   <BODY>
   <OBJECT ID="AmbientBugTest1" WIDTH=320 HEIGHT=240
      CLASSID="CLSID:<Insert User Control's Class ID here.>">
     <PARAM NAME="_ExtentX" VALUE="8467">
     <PARAM NAME="_ExtentY" VALUE="6350"></OBJECT>
   </BODY>
   </HTML>
   					

6. Click on both command buttons.
