Add button annotation to the current page of the doc.

[C#]
ButtonAnnotation(Doc doc, XRect rect, string caption)

[Visual Basic]
ButtonAnnotation(doc As Doc, rect As XRect, caption As string)


Add button annotation to the current page of the doc.

Note that the annotation created using this constructor is meaningless until it is connected with a Field. For this reason you are likely to want to use Doc.Form.AddButton rather than this call.
