Public Shared ReadOnly OutlineStylesAttribute As AutomationTextAttribute

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in TextPatternIdentifiers.

UI Automation clients get the value of the attribute by calling GetAttributeValue.

Values for this attribute are of type OutlineStyles. The default value is None.

The following example shows how to obtain an attribute value for a range of text in Microsoft Notepad.

System_CAPS_noteNote

Microsoft Notepad is used as the text provider for example purposes only. Microsoft Notepad is not guaranteed to support the attribute value being requested.

Private Sub GetOutlineStylesAttribute()
    ' Start application.
    Dim p As Process = Process.Start("Notepad.exe", "text.txt")

    ' target --> The root AutomationElement.
    Dim target As AutomationElement = AutomationElement.FromHandle(p.MainWindowHandle)

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

    Dim textProvider As AutomationElement = target.FindFirst(TreeScope.Descendants, cond)

    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
    End If

    Dim oAttribute As Object = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.OutlineStylesAttribute)
    If (oAttribute = TextPattern.MixedAttributeValue) Then
        Console.WriteLine("Mixed outline styles.")
    Else
        Console.WriteLine(oAttribute.ToString())
    End If
End Sub
