Public Function FindText (text As String, backward As Boolean, ignoreCase As Boolean) As TextPatternRange

A text range matching the specified text; otherwise null (Nothing in Visual Basic).

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

        return null;
    }

    // Find 'text' in selection range
    return tprSelection[0].FindText("text", false, true);
}

Private Function TextFromSelection(ByVal target As AutomationElement) As TextPatternRange
    ' Specify the control type we're looking for, in this case 'Document'
    Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)

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

    If (textpatternPattern Is Nothing) Then
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.")
        Return Nothing
    End If
    Dim currentSelection As TextPatternRange() = textpatternPattern.GetSelection()
    ' Find 'text' in selection range
    Return currentSelection(0).FindText("text", False, True)
End Function

There is no differentiation between hidden and visible text. UI Automation clients can use IsHiddenAttribute to check text visibility.
