    ''' <summary> 
    ''' Find a UI Automation child element by ID. 
    ''' </summary> 
    ''' <param name="controlName">Name of the control, such as "button1"</param> 
    ''' <param name="rootElement">Parent element, such as an application window, or the  
    ''' AutomationElement.RootElement when searching for the application window.</param> 
    ''' <returns>The UI Automation element.</returns> 
    Private Function FindChildElement(ByVal controlName As String, ByVal rootElement As AutomationElement) _
        As AutomationElement
        If controlName = "" OrElse rootElement Is Nothing Then 
            Throw New ArgumentException("Argument cannot be null or empty.")
        End If 
        ' Set a property condition that will be used to find the main form of the 
        ' target application. In the case of a WinForms control, the name of the control 
        ' is also the AutomationId of the element representing the control. 
        Dim propCondition As New PropertyCondition(AutomationElement.AutomationIdProperty, _
            controlName, PropertyConditionFlags.IgnoreCase)

        ' Find the element. 
        Return rootElement.FindFirst(TreeScope.Element Or TreeScope.Children, propCondition)
