Contoh

Contoh berikut menunjukkan cara mendapatkan nilai atribut untuk rentang teks di Microsoft Notepad.

Catatan

Microsoft Notepad digunakan sebagai penyedia teks hanya untuk tujuan contoh. Microsoft Notepad tidak dijamin untuk mendukung nilai atribut yang diminta.

private void GetStrikethroughColorAttribute()
{
    // Start application.
    Process p = Process.Start("Notepad.exe", "text.txt");

    // target --> The root AutomationElement.
    AutomationElement target = AutomationElement.FromHandle(p.MainWindowHandle);

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

    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;
    }

    Object oAttribute = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.StrikethroughColorAttribute);
    if (oAttribute == TextPattern.MixedAttributeValue)
    {
        Console.WriteLine("Mixed strikethrough colors.");
    }
    else
    {
        Console.WriteLine(oAttribute.ToString());
    }
}

Private Sub GetStrikethroughColorAttribute()
    ' 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.StrikethroughColorAttribute)
    If (oAttribute = TextPattern.MixedAttributeValue) Then
        Console.WriteLine("Mixed strikethrough colors.")
    Else
        Console.WriteLine(oAttribute.ToString())
    End If
End Sub

Keterangan

Pengidentifikasi ini digunakan oleh aplikasi klien Automation UI. Penyedia Automation UI harus menggunakan bidang yang setara di TextPatternIdentifiers.

Klien Automation UI mendapatkan nilai atribut dengan memanggil GetAttributeValue.

Nilai untuk atribut ini berjenis Int32. Nilai defaultnya adalah zero.
