AddXRecord 方法 （ActiveX）
在任何字典中创建 XRecord 对象。 支持的平台：仅限 AutoCAD for Windows;AutoCAD LT for Windows 不支持 言论没有其他评论。 例子VBA： Sub Example_AddXRecord()
' This example creates a new XRecord if one does not exist,
' appends data to the XRecord, and then reads it back. To see data being added,
' run the example more than once.
