Public ReadOnly Property Id As Guid
Property Value
The GUID for the current StylusPointProperty.
Examples
The following example creates the StylusPointDescription from a StylusPointCollection and gets the information for each StylusPointPropertyInfo in the StylusPointDescription.
private void WriteDescriptionInfo(StylusPointCollection points)
{
StylusPointDescription pointsDescription = points.Description;
ReadOnlyCollection<StylusPointPropertyInfo> properties =
pointsDescription.GetStylusPointProperties();
StringWriter descriptionStringWriter = new StringWriter();
descriptionStringWriter.Write("Property Count:{0}", pointsDescription.PropertyCount.ToString());
foreach (StylusPointPropertyInfo property in properties)
{
// GetStylusPointPropertyName is defined below and returns the
// name of the property.
descriptionStringWriter.Write("name = {0}", GetStylusPointPropertyName(property).ToString());
descriptionStringWriter.WriteLine(" Guid = {0}", property.Id.ToString());
descriptionStringWriter.Write(" IsButton = {0}", property.IsButton.ToString());
descriptionStringWriter.Write(" Min = {0}", property.Minimum.ToString());
descriptionStringWriter.Write(" Max = {0}", property.Maximum.ToString());
descriptionStringWriter.Write(" Unit = {0}", property.Unit.ToString());
descriptionStringWriter.WriteLine(" Res {0}", property.Resolution.ToString());
}
descriptionOutput.Text = descriptionStringWriter.ToString();
}
Private Sub WriteDescriptionInfo(ByVal points As StylusPointCollection)
Dim pointsDescription As StylusPointDescription = points.Description
Dim properties As ReadOnlyCollection(Of StylusPointPropertyInfo) = _
pointsDescription.GetStylusPointProperties()

descriptionStringWriter.Write("Property Count:{0}", pointsDescription.PropertyCount.ToString())
Dim pointProperty As StylusPointPropertyInfo
For Each pointProperty In properties
' GetStylusPointPropertyName is defined below and returns the
' name of the property.
descriptionStringWriter.Write("name = {0}", GetStylusPointPropertyName(pointProperty).ToString())
descriptionStringWriter.WriteLine(" Guid = {0}", pointProperty.Id.ToString())
descriptionStringWriter.Write(" IsButton = {0}", pointProperty.IsButton.ToString())

descriptionStringWriter.WriteLine(" Res {0}", pointProperty.Resolution.ToString())
Next pointProperty
descriptionOutput.Text = descriptionStringWriter.ToString()
End Sub
