沙发，谢谢了，能介绍一下吗？

nxy_918 · 发表于 2004-11-12 16:52:00

可否介绍一下，有哪些功能的增强？

雪山飞狐_lzh · 发表于 2004-11-12 19:30:00

比较一下下面两段代码，功能是一样的 Sub test1()

收下了，仔细研究研究。简化了多。

建议增加一些常用属性的修改，如颜色、线型、图层等。以前象移动、复制等功能。这也是我以前想做的。
因为AX的选择集就这一点和LISP的选择集不同，操作起来也不方便。

按照老大的意见已做更改，见一楼代码，大家看看还有什么要加的？

这是测试代码

Sub test1()
Dim ss As New TlsSel
ss.Init "TlsSel1"
ss.SetFilterType 0, 8
ss.SetFilterData "Line", "0"
ss.SelectObjectOnScreen
ss.GetBoundingBox p1, p2
' OutputPoint p1
' OutputPoint p2
ss.Move p1, p2
End Sub
