This property determines whether underlining is applied to text.

In this example we add some underlined text to a document.

Set theDoc = Server.CreateObject("ABCpdf3.Doc")
theText = "Gallia est omnis divisa in partes tres, quarum unam incolunt Belgae, aliam Aquitani, tertiam qui ipsorum lingua Celtae, nostra Galli appellantur."
theDoc.Rect.Inset 20, 40
theDoc.TextStyle.Size = 96
theDoc.TextStyle.Underline = True
theDoc.AddText theText
theDoc.Save "c:\mypdfs\styleunderline.pdf"
