WPF WebBrowser invoke a VBScript and retrieve its return value

Question

Hi

I have a WPF WebBrowser which loads a HTML page with vbScript functions on it from intranet I want to execute one of these functions and retrieve the return value.

Unfortunately I have no ability to change the the intranet page

The function returns a boolean value and is as follows

Function IsAltered(strMode)

' This procedure checks to see if Changes have been made without saving.
Dim objItem, blnIsAltered
IsAltered = False
blnIsAltered = False

For Each objItem In window.document.all
 If (objItem.tagName = "INPUT" And objItem.className <> "Lbl" And objItem.className <> "NAF" And objItem.className <> "PreDispNoChange") Or _
    objItem.tagname = "SELECT" Or objItem.tagname = "TEXTAREA"  Then
  If Left(objItem.Id, 3) <> "hid" And objItem.Type <> "hidden" And objItem.Style.Visibility <> "hidden" Then
   If HasValueChanged(ObjItem.Id, Trim(objItem.Value)) Then
    blnIsAltered = True
    Exit For
   End if
  End If
 End If
Next
IsAltered = blnIsAltered   End Function

Can somebody suggest a way of implementing this

Thanks

System.Windows.Controls.WebBrowser has a method called InvokeScript, which, according to the documentation "Executes a script function that is implemented by the currently loaded document."

You might want to try that.
