Voorbeelden

 private TextPatternRange TextFromSelection(AutomationElement target)
{
    // Specify the control type we're looking for, in this case 'Document'
    PropertyCondition cond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document);

    // target --> The root AutomationElement.
    AutomationElement textProvider = target.FindFirst(TreeScope.Descendants, cond);

    TextPattern textpatternPattern = textProvider.GetCurrentPattern(TextPattern.Pattern) as TextPattern;

    if (textpatternPattern == null)
    {
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.");
        return null;
    }
    TextPatternRange[] tprSelection = textpatternPattern.GetSelection();
    // Find 'text' in selection range
    return tprSelection[0].FindText("text", false, true);
}

    Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)

    If (textpatternPattern Is Nothing) Then

        Return Nothing

Opmerkingen

Er is geen onderscheid tussen verborgen en zichtbare tekst. UI Automation clients kunnen IsHiddenAttribute gebruiken om de zichtbaarheid van tekst te controleren.
