我定义了一个动态数组

约翰乔

请问如何将一系列相互连接的PL生成面域啊?

我定义了一个动态数组

Dim polylineobj() as Acadpolyline

..................

do

.......

set polylineobj() =thisdrawing...........addpolyline(points)

.......

loop

生成的最后一条PL与第一条的起点相连

再生成面域addregion(polylineobj)

运行的时候提示addregion方法错误,是不是不能这样生成面域啊,

你看看帮助文件就行了

从来没有见过给数组赋值的，VB不是VC，VC倒可以给它一个指针！
