''' <returns>
''' A collection of automation elements satisfying 
''' the specified condition(s).
''' </returns>
'''--------------------------------------------------------------------
Private Function FindAutomationElement( _
ByVal targetApp As AutomationElement) As AutomationElementCollection
    If targetApp Is Nothing Then
        Throw New ArgumentException("Root element cannot be null.")
    End If

    Dim conditionIsReadOnly As New PropertyCondition( _
    RangeValuePattern.IsReadOnlyProperty, False)

    Return targetApp.FindAll(TreeScope.Descendants, conditionIsReadOnly)
