when running the following code in the VS 2005 environment
(AxWebBrowser1 is a microsoft web browser):

Public Class Form1

Dim WB As Microsoft.Office.Interop.Excel.Workbook

Private Sub AxWebBrowser1_NavigateComplete2(ByVal sender As Object,
ByVal e As AxSHDocVw.DWebBrowserEvents2_NavigateComplete2Event) Handles
AxWebBrowser1.NavigateComplete2
WB = e.pDisp.Document
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
AxWebBrowser1.Navigate("c:\test.xls")
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button2.Click
WB.Worksheets(1).Range("b4") = "AAA"
End Sub
End Class

I recieve the error :
