You could always use SendKeys and CTRL+F to display the Find(on this page) dialogue box. Or try something like this:
VB Code:
Private Sub Form_Load()
WebBrowser1.Navigate "http://www.yahoo.com"
End Sub
Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Dim strFind As String, strHtml As String
strFind = "Calendar"
If pDisp Is WebBrowser1.Object Then
strHtml = WebBrowser1.Document.documentelement.innerHTML
If InStr(strHtml, strFind) Then
MsgBox "Word Found"
End If
End If
End Sub
